ERPNext is an Enterprise Resource Planning (ERP) suite that leverages the power and flexibility of open-source technologies. It excels at managing core business processes such as finance, sales, human resources, manufacturing, purchases, services, helpdesk needs, and more. Among the benefits of implementing a system like ERPNext are:
In this tutorial you will install and configure an ERPNext stack on one server running Ubuntu 20.04. This will allow you to configure your stack for various development or production environments depending on your needs, and it will prepare you to build a more complex, fault-tolerant architecture.
sudouser. You can set up your server and user by following our Ubuntu 20.04 initial server setup guide.
Note: When choosing your server’s specifications, keep in mind that ERP systems are resource-intensive. This guide calls for one server with 4 GB of RAM, which is sufficient for basic use cases, but specific hardware requirements may vary depending on the number of users as well as your business size.
Although configuring a firewall for development is optional, for production it is a mandatory security practice.
You will need to open the following ports on your ERPNext server:
443/tcpfor HTTP and HTTPS respectively
3306/tcpfor MariaDB connection (recommended only if you need remote access to database)
25/tcpfor IMAP and STMP respectively
22/tcpfor SSH (if you have not already enabled
OpenSSHin your UFW settings)
8000/tcpfor testing your platform before deploying to production
To open multiple ports at once you can use the following command:
- sudo ufw allow 22,25,143,80,443,3306,8000/tcp
Alternatively, you can allow connections from specific IP addresses on specific ports using this command:
- sudo ufw allow from server_IP to any port port_number
After opening all necessary ports enable the firewall:
- sudo ufw enable
Now confirm the status of your firewall:
- sudo ufw status
UFW will output a list of your enabled rules. Make sure ERPNext’s necessary ports are open:
OutputStatus: active To Action From -- ------ ---- 22,25,80,143,443,3306,8000/tcp ALLOW Anywhere 22,25,80,143,443,3306,8000/tcp (v6) ALLOW Anywhere (v6)
For more information regarding UFW’s configuration, consult our guide on how to set up a firewall with UFW on Ubuntu 20.04.
Setting up a proper firewall is the first of two preliminary steps. Now you will configure keyboard mapping and character encoding on your server.
It’s highly recommended that you configure keyboard mapping for the console as well as the language and the character encoding on your host. This is necessary to avoid possible issues during the ERPNext 12 installation process. Take note that this configuration has nothing to do with the UI language on your actual ERPNext platform, but with the system locale configuration.
First, update your server:
- sudo apt update
Now configure keymap, language, and character encoding:
- sudo localectl set-keymap us && sudo localectl set-locale LANG=en_US.utf8
localectl utility is used by Ubuntu 20.04 and other Linux distributions to control and change system-wide locale and keyboard layout settings before the user logs in, which is exactly what ERPNext 12 requires.
You will also need to add the following lines to your
/etc/environment file. Use
nano or your preferred text editor to open the file:
- sudo nano /etc/environment
Now add the following content:
LC_ALL=en_US.UTF-8 LC_CTYPE=en_US.UTF-8 LANG=en_US.UTF-8
Save and close the file.
Reboot your server to apply all changes:
- sudo reboot
Give your server a few minutes to reboot and then use
ssh to reenter your instance. You are now ready to install your database.
Now you will add MariaDB to your server stack. ERPNext 12 requires MariaDB 10.2+ for proper operation. Because Ubuntu 20.04 includes MariaDB 10.3 in its official repositories you can install this version using the
- sudo apt install mariadb-server
Alternatively, if prefer a newer MariaDB version, you can follow Step 3 of our guide on how to install an ERPNext Stack on Ubuntu 18.04. This will guide you through MariaDB’s online repository wizard, which will help you install the newest version—MariaDB 10.5.
mariadb-server, install the following packages:
- sudo apt install python3-mysqldb libmysqlclient-dev
ERPNext 12 is a Python application and thus it requires the
python3-mysqldb library for database management.
libmysqlclient-dev is required to access certain MariaDB developer features.
Next, add an extra layer of security to the MariaDB server by running the
- sudo mysql_secure_installation
mysql_secure_installation script will prompt you with several questions:
N. Using the default password along with Unix authentication is the recommended setup for Ubuntu-based systems because the root account is closely related to automated system maintenance tasks.
Yto all those questions.
After completing the
mysql_secure_installation script, MariaDB will start running using its default configuration. The standard ERPNext installation uses MariaDB’s root user for all database operations. While that approach may be convenient on single server setups, it is not considered a good security practice. Therefore, in the next section you will learn how to avoid this issue by creating a new user with special privileges.
ERPNext expects to use MariaDB’s root user for managing database connections, but this is not always ideal. To overcome this limitation and let a non-root user manage MariaDB you will now manually create a database named after the user. Then you will be able to assign special privileges to the new user to drive ERPNext database operations.
Open up the MariaDB prompt:
- sudo mysql
Now create a new database named after the user you want to assign for MariaDB connections. This tutorial will use
sammy but you can choose a different name:
- CREATE DATABASE sammy;
Confirm that the database was created using this SQL statement:
- SHOW DATABASES;
You will see an output similar to this:
Output+--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | sammy | +--------------------+
Now create the MariaDB user
sammy with privileges similar to root and then give the user a strong password of your choice. Keep the password in a secure place; you will need it later:
- GRANT ALL PRIVILEGES ON *.* TO 'sammy'@'%' IDENTIFIED BY 'mariadb_password' WITH GRANT OPTION;
Now confirm both the user creation and the new user’s privileges:
- SELECT host, user, Super_priv FROM mysql.user;
You will see an output like this:
Output+-----------+-------+------------+ | Host | User | Super_priv | +-----------+-------+------------+ | localhost | root | Y | | localhost | mysql | Y | | % | sammy| Y | +-----------+-------+------------+ 3 rows in set (0.001 sec)
Now flush privileges to apply all changes:
- FLUSH PRIVILEGES;
Once you finish, exit the session:
Now that you have created a database user you only need to fine-tune MariaDB to ensure proper ERPNext 12 operation. Fortunately, the ERPNext team provides an excellent configuration template that you will use as a starting point for your implementation. In the next section, you will learn how to properly configure the MariaDB database using that template.
With MariaDB installed and secured it’s time to fine-tune it for ERPNext connections.
- sudo systemctl stop mariadb
nano or your favorite text editor to create a MariaDB configuration file called
- sudo nano /etc/mysql/mariadb.conf.d/mariadb.cnf
Now add ERPNext’s official configuration template:
[mysqld] # GENERAL # user = mysql default-storage-engine = InnoDB socket = /var/lib/mysql/mysql.sock pid-file = /var/lib/mysql/mysql.pid # MyISAM # key-buffer-size = 32M myisam-recover = FORCE,BACKUP # SAFETY # max-allowed-packet = 256M max-connect-errors = 1000000 innodb = FORCE # DATA STORAGE # datadir = /var/lib/mysql/ # BINARY LOGGING # log-bin = /var/lib/mysql/mysql-bin expire-logs-days = 14 sync-binlog = 1 # REPLICATION # server-id = 1 # CACHES AND LIMITS # tmp-table-size = 32M max-heap-table-size = 32M query-cache-type = 0 query-cache-size = 0 max-connections = 500 thread-cache-size = 50 open-files-limit = 65535 table-definition-cache = 4096 table-open-cache = 10240 # INNODB # innodb-flush-method = O_DIRECT innodb-log-files-in-group = 2 innodb-log-file-size = 512M innodb-flush-log-at-trx-commit = 1 innodb-file-per-table = 1 innodb-buffer-pool-size = 5462M innodb-file-format = barracuda innodb-large-prefix = 1 collation-server = utf8mb4_unicode_ci character-set-server = utf8mb4 character-set-client-handshake = FALSE max_allowed_packet = 256M # LOGGING # log-error = /var/lib/mysql/mysql-error.log log-queries-not-using-indexes = 0 slow-query-log = 1 slow-query-log-file = /var/lib/mysql/mysql-slow.log # CONNECTIONS # pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock bind-address = 0.0.0.0 [mysql] default-character-set = utf8mb4 [mysqldump] max_allowed_packet=256M
Save and close the file. For more detailed information about these configurations, review this template file on ERPNext’s Github repo. This is a useful starting point for exploring these options.
The configuration file,
/etc/mysql/mariadb.conf.d/mariadb.cnf, complements and also overrides a few values included in the default MariaDB configuration located at
/etc/mysql/my.cnf. This file gives you a curated template that greatly enhances database performance for ERPNext. Keep in mind, however, that while this template is a great starting point nothing prevents you from improving MariaDB’s performance even further by adjusting these parameters to fit your needs.
Since ERPNext relies on the database connection for almost all of its internal operations, it is a good idea to test the connection before continuing.
- sudo systemctl start mariadb
To test the connection you can use the following command. Remember to replace
mariadb_password with your credentials:
- mysql --user sammy --password mariadb_password --host=localhost --protocol=tcp --port=3306 test
You will see an output showing MariaDB’s basic help content and several parameters. This means your connection was successful:
Outputmysql Ver 15.1 Distrib 10.4.13-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2 Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

If you need to make any adjustments to MariaDB’s settings or fix any errors, remember to reload the service using the following command:
- sudo systemctl restart mariadb
Once you are done, enable MariaDB:
- sudo systemctl enable mariadb
Now that you have tested the database connection, you can continue with the installation of your ERPNext application.
Now that your database backend is ready you can continue setting up your ERPNext web application. In this section, you will learn how to install and configure all components required by ERPNext 12 and then install the application itself.
Start by preparing the server with all the system packages required by ERPNext 12. Install system-wide dependencies using the following command:
- sudo DEBIAN_FRONTEND=noninteractive apt install -y curl build-essential python3-testresources python3-setuptools python3-dev libffi-dev python3-pip libcurl4 dnsmasq fontconfig git htop libcrypto++-dev libfreetype6-dev liblcms2-dev libwebp-dev libxext6 libxrender1 libxslt1-dev libxslt1.1 libffi-dev ntpdate postfix python3-dev python-tk screen vim xfonts-75dpi xfonts-base zlib1g-dev apt-transport-https libsasl2-dev libldap2-dev libcups2-dev pv libjpeg8-dev libtiff5-dev tcl8.6-dev tk8.6-dev libdate-manip-perl logwatch
DEBIAN_FRONTEND=noninteractive variable has been passed to the installation command in order to avoid Postfix prompts. For detailed information regarding Postfix configuration please read our guide on How To Install and Configure Postfix on Ubuntu 20.04
pip3, which is Python’s standard package manager, and then install the latest versions of three additional Python modules:
- sudo -H python3 -m pip install --upgrade setuptools cryptography psutil
setuptools facilitates the installation and upgrading of Python packages,
cryptography adds encryption capabilities to your stack, and
psutil aids with system monitoring. Now that you have installed all necessary global dependencies, you will now install all the services and libraries required by ERPNext 12.
ERPNext 12 can work with version 8+ of the Node.js server environment. In fact, at the time of this writing, the official ERPNext
easy_install script uses Node 8. But from a security perspective, it’s advisable to install a newer version because Node 8 reached its End Of Life (EOL) in 2020 and thus will not receive any more security patches. At the time of this writing, Ubuntu 20.04 contains version 10.19 of Node.js. Although this version is still maintained, for similar reasons (EOL in less than a year) it’s highly advisable to avoid using it. For this guide, Node.js version 12 LTS will be installed along with the corresponding
yarn package managers. Please note that the Frappe framework uses
yarn to install dependencies. If you decide to use an alternative installation method then make sure that you end up with version 1.12+ of
yarn running in your system.
Add the NodeSource repository to your system:
- curl -sL https://deb.nodesource.com/setup_12.x -o nodesource_setup.sh
Now you can inspect the contents of the downloaded script:
- sudo nano nodesurce_setup.sh
Once you are satisfied with the script’s contents you can run the script:
- sudo bash nodesource_setup.sh
This script will automatically update the
apt list. Now you can install
nodejs on your server:
- sudo apt install nodejs
yarn globally using the
npm package manager:
- sudo npm install -g yarn
Now that you have installed Node you can continue to configure
wkhtmltopdf for your platform.
ERPNext uses the
wkhtmltopdf open source tool to convert HTML content into PDF using the Qt WebKit rendering engine. This feature is mostly used for printing invoices, quotations, and other reports. In the case of ERPNext 12, a specific version of
wkhtmltopdf is required,
0.12.5 with patched Qt.
wkhtmltopdf, start by switching to a suitable directory to download the package, in this case
- cd /tmp
Download the appropriate
wkhtmltopdf version and package for Ubuntu 20.04 from the project’s page:
- wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.bionic_amd64.deb
Now install the package using the
- sudo dpkg -i wkhtmltox_0.12.5-1.bionic_amd64.deb
Next, copy all relevant executables to your
- sudo cp /usr/local/bin/wkhtmlto* /usr/bin/
Once the files are in place, change their permissions to make them executable:
- sudo chmod a+x /usr/bin/wk*
wkhtmltopdf is properly installed we will add Redis to our database stack.
ERPNext 12 uses Redis to enhance MariaDB’s performance. Specifically, Redis assists with caching.
First, install Redis from the official Ubuntu 20.04 repository:
- sudo apt install redis-server
Then enable Redis on startup:
- sudo systemctl enable redis-server
Now that you have added Redis to your stack let’s take a moment to summarize what you have accomplished so far. Up to this point, you have installed all the major components required by ERPNext 12, which include:
wkhtmltopdfPDF documents generator
Whether you are installing the ERP system for development or for production, you are now ready for the next step, which is installing the Frappe full-stack framework and the actual ERPNext 12 web application.
Now that you have installed all of ERPNext’s stack requirements you can unleash the flexibility of Frappe’s
bench command-line utility. The
bench CLI was designed with the purpose of assisting users in the process of installing, setting up, and managing applications like ERPNext that are based on the Frappe Framework. In the coming sections, you will install the
bench CLI and then use it to complete the process of setting up ERPNext 12.
Make sure that the Frappe user (in this case
sammy) has the proper rights on its
- sudo chown sammy -R /home/sammy
Now clone the
frappe/bench repository to your home directory. Remember to replace
sammy with your system username:
- git clone https://github.com/frappe/bench /home/sammy/.bench --depth 1 --branch master
- sudo pip3 install -e /home/sammy/.bench
This guide is assuming that you are installing ERPNext 12 for testing/production scenarios and thus that you are using the
master branch. But if your intention is to develop applications or custom ERPNext modules, then the
develop branch might be a better option. In either case, you are now prepared to install the Frappe Framework. This will be your final step before installing ERPNext itself.
In this section, you will create a Frappe environment using the
During Frappe’s installation you may exceed Ubuntu’s file watch limit, which by default is set to 8192. To avoid this issue set a higher limit using the following command:
- echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
tee command will append the contents of your
echo command to the called file while also printing the output to your console.
Next, initialize Frappe Framework 12. Replace Sammy with your system username:
- bench init /home/sammy/frappe-bench --frappe-path https://github.com/frappe/frappe --frappe-branch version-12 --python python3
During execution you may see one error about your path, along with several warnings. Let the process continue until the end. Once it’s finished, you will see an output similar to the following one, indicating that your environment was successfully created:
Output... Done in 82.23s. INFO:bench.utils:setting up backups no crontab for sammy SUCCESS: Bench /home/sammy/frappe-bench initialized
bench init process could halt if a
spawn ENOMEM error is encountered. This error is caused when your system runs out of memory. You must fix the issue before continuing, either by installing more physical memory or allocating SWAP space.
Let’s take a closer look at the command used to create the environment:
/home/sammy/frappe-benchis the path where the Frappe Framework, the websites, and associated applications will be installed. A new directory, called
frappe-benchin this example, will be created to accommodate all necessary files.
--frappe-pathpoints to Frappe repository, which in this case is the official Github repository.
--frappe-branchis the Frappe version to be installed. Because you want to install ERPNext 12, the chosen version is Frappe 12.
--pythonis the Python version that will be used. ERPNext 12 requires Python 3.6+. Prior versions, however, still use Python 2.7.
For more information regarding
bench CLI commands please refer to the Bench Commands Cheatsheet.
The flexibility offered by the Frappe framework goes way beyond using isolated environments. You can also create different websites and install applications into them.
In this section, you will set up a Frappe-based site and then install the ERPNext 12 application on it.
Change to the directory where Frappe was initialized.
- cd /home/sammy/frappe-bench
Before continuing, you will need to install specific versions of Python libraries
pandas into the Frappe virtual environment. Install these packages using the following command:
- ./env/bin/pip install numpy==1.18.5 && ./env/bin/pip install pandas==0.24.2
At this point the installation might halt for about 10 to 20 minutes while displaying this message:
Output... Building wheel for pandas (setup.py) ... -
This has to do with a bug related to
pandas and Ubuntu 20.04, which, at the time of writing, is still rather new. Nevertheless the packages will build, and once they complete you will see an output like this:
Output... Successfully built pandas Installing collected packages: pandas Successfully installed pandas-0.24.2
Now, you can continue with the installation. Download ERPNext 12 from its repository using the
- bench get-app erpnext https://github.com/frappe/erpnext --branch version-12
Next, create the new site, replacing
your_domain with the domain that you have associated with this server’s IP:
- bench new-site your_domain --admin-password 'erpnext_admin_password' --mariadb-root-username sammy --mariadb-root-password 'mariadb_password'
Let’s take a moment to review the options used in the command above:
bench new-sitecreates a new site based on the Frappe Framework.
your_domainis the name for the new site. Make sure that your domain’s DNS has an A record pointing at your server’s IP.
erpnext_admin_passwordis the desired password for ERPNext’s Administrator user. Keep this password in a safe place—you will need it shortly.
mariadb_passwordis the password that you created at the beginning of the guide for the MariaDB user
Following this, install the ERPNext application onto the site:
- bench --site your_domain install-app erpnext
Once the installation completes, you will have a working ERPNext 12 application. Now let’s test it using a
- bench start
The above will initiate a real-time monitoring console showing you various messages regarding the webserver and other services. Open a web browser and navigate to
localhost:8000 (for local installations) or
your_domain:8000 (if you are using a remote server). You will see the ERPNext login screen (we will proceed with login and setup in a later step, once we have made our site production-ready).
After visiting your test deployment, return to your terminal and press
CTRL+C. This will stop ERPNext and exit the monitoring console.
If your main goal is creating modules or modifying ERPNext 12, then you could stop at this point. No more components are needed for development purposes. However, if what you need is a production-ready system that does not require a manual initialization, then you will need to install and configure a few additional components. This is your next step.
Although your ERPNext 12 application is ready, the system as a whole is not yet prepared for production. To ensure ERPNext’s reliability and security you will need to enable a few additional services:
80(HTTP) or port
Up to this point, you have installed and configured ERPNext 12 manually, which has allowed you to customize the process to match any particular use case. Nevertheless, for the rest of the production setup, you can leverage the convenience of the
bench CLI and let it automate the installation and configuration of these remaining services.
Ensure you are in the Frappe working directory:
- cd /home/sammy/frappe-bench
Now use the following command to finish setting up ERPNext 12 for production:
- sudo bench setup production sammy --yes
The above will install and configure Nginx, Supervisor, and Fail2Ban and set
sammy as the production environment owner.
The configuration files created by the
bench command are:
/etc/fail2ban/jail.d/nginx-proxy.confand one filter located at
These default configurations will suffice for this tutorial, but you should feel free to explore and adjust these files to match your requirements. You can stop all services by running:
- sudo supervisorctl stop all
And then, once you are ready, you can restart your services:
- sudo supervisorctl start all
Now you are ready to test your installation.
First of all, verify that key production services are running. Use the following
systemctl command and then pipe it to
- systemctl list-unit-files | grep 'fail2ban\|nginx\|supervisor'
You will see an output like this:
Outputfail2ban.service enabled nginx.service enabled supervisor.service enabled
After confirming that everything is working as expected, you can test ERPNext 12 live on your server. Open your favorite browser and navigate your_domain, or whereever you are hosting your ERPNext 12 application.
After a few seconds, you should see the ERPNext 12 login screen. Use Administrator for the username (email) and the
erpnext_admin_password you created previously for the password.
In the next screen you will see a dropdown menu where you can select the UI language for the application:
Following language selection, ERPNext will prompt you about your country, timezone, and currency:
Once you complete your region information, you will be able to create your first ERPNext user. The information you provide will be used as the user’s login credentials.
In the next screen, you will be asked about what ERPNext calls Domains. If you are not sure what your domain is, then select Distribution and click the Next button.
Next, you will need to provide a company name and abbreviation.
On the last screen, ERPNext will ask you what your company does, its bank name, the type of charts of accounts, and the fiscal year period. You will be able to enter additional banks later. For now, fill in all the fields as you like and then click the Complete Setup button.
Next, you will see a progress bar.
Once the setup process completes, the ERPNext 12 main Dashboard will appear.
You now have fully installed and configured an ERPNext 12 application.
Now that you have properly installed your ERPNext 12 application, you might want to start implementing the system for your business needs. A good starting point is clicking the Getting Started button on the ERPNext Dashboard. ERPNext will then help you configure the platform for all your business and e-commerce needs.
You may also wish to enhance ERPNext’s speed. If that is the case, then you can read about ERPNext performance tuning, which will guide you through best practices and how to debug performance-related issues.
