While many users need the functionality of a database management system like MySQL, they may not feel comfortable interacting with the system solely from the MySQL prompt.
phpMyAdmin was created so that users can interact with MySQL through a web interface. In this guide, we’ll discuss how to install and secure phpMyAdmin so that you can safely use it to manage your databases from an Ubuntu 16.04 system.
Before you get started with this guide, you need to have some basic steps completed.
First, we’ll assume that you are using a non-root user with sudo privileges, as described in steps 1-4 in the initial server setup of Ubuntu 16.04.
We’re also going to assume that you’ve completed a LAMP (Linux, Apache, MySQL, and PHP) installation on your Ubuntu 16.04 server. If this is not completed yet, you can follow this guide on installing a LAMP stack on Ubuntu 16.04.
Finally, there are important security considerations when using software like phpMyAdmin, since it:
For these reasons, and because it is a widely-deployed PHP application which is frequently targeted for attack, you should never run phpMyAdmin on remote systems over a plain HTTP connection. If you do not have an existing domain configured with an SSL/TLS certificate, you can follow this guide on securing Apache with Let’s Encrypt on Ubuntu 16.04.
Once you are finished with these steps, you’re ready to get started with this guide.
To get started, we will install phpMyAdmin from the default Ubuntu repositories.
We can do this by updating our local package index and then using the
apt packaging system to pull down the files and install them on our system:
- sudo apt-get update
- sudo apt-get install phpmyadmin php-mbstring php-gettext
This will ask you a few questions in order to configure your installation correctly.
Warning: When the first prompt appears, apache2 is highlighted, but not selected. If you do not hit Space to select Apache, the installer will not move the necessary files during installation. Hit Space, Tab, and then Enter to select Apache.

The installation process actually adds the phpMyAdmin Apache configuration file into the
/etc/apache2/conf-enabled/ directory, where it is automatically read.
The only thing we need to do is explicitly enable the PHP
mbstring extensions, which we can do by typing:
- sudo phpenmod mcrypt
- sudo phpenmod mbstring
Afterwards, you’ll need to restart Apache for your changes to be recognized:
- sudo systemctl restart apache2
You can now access the web interface by visiting your server’s domain name or public IP address followed by
You can now log into the interface using the
root username and the administrative password you set up during the MySQL installation.
When you log in, you’ll see the user interface, which will look something like this:
We were able to get our phpMyAdmin interface up and running fairly easily. However, we are not done yet. Because of its ubiquity, phpMyAdmin is a popular target for attackers. We should take extra steps to prevent unauthorized access.
One of the easiest way of doing this is to place a gateway in front of the entire application. We can do this using Apache’s built-in
.htaccess authentication and authorization functionalities.
First, we need to enable the use of
.htaccess file overrides by editing our Apache configuration file.
We will edit the linked file that has been placed in our Apache configuration directory:
- sudo nano /etc/apache2/conf-available/phpmyadmin.conf
We need to add an
AllowOverride All directive within the
<Directory /usr/share/phpmyadmin> section of the configuration file, like this:
<Directory /usr/share/phpmyadmin> Options FollowSymLinks DirectoryIndex index.php AllowOverride All . . .
When you have added this line, save and close the file.
To implement the changes you made, restart Apache:
- sudo systemctl restart apache2
Now that we have enabled
.htaccess use for our application, we need to create one to actually implement some security.
In order for this to be successful, the file must be created within the application directory. We can create the necessary file and open it in our text editor with root privileges by typing:
- sudo nano /usr/share/phpmyadmin/.htaccess
Within this file, we need to enter the following information:
AuthType Basic AuthName "Restricted Files" AuthUserFile /etc/phpmyadmin/.htpasswd Require valid-user
Let’s go over what each of these lines mean:
AuthType Basic: This line specifies the authentication type that we are implementing. This type will implement password authentication using a password file.
AuthName: This sets the message for the authentication dialog box. You should keep this generic so that unauthorized users won’t gain any information about what is being protected.
AuthUserFile: This sets the location of the password file that will be used for authentication. This should be outside of the directories that are being served. We will create this file shortly.
Require valid-user: This specifies that only authenticated users should be given access to this resource. This is what actually stops unauthorized users from entering.
When you are finished, save and close the file.
The location that we selected for our password file was “
/etc/phpmyadmin/.htpasswd”. We can now create this file and pass it an initial user with the
- sudo htpasswd -c /etc/phpmyadmin/.htpasswd username
You will be prompted to select and confirm a password for the user you are creating. Afterwards, the file is created with the hashed password that you entered.
If you want to enter an additional user, you need to do so without the
-c flag, like this:
- sudo htpasswd /etc/phpmyadmin/.htpasswd additionaluser
Now, when you access your phpMyAdmin subdirectory, you will be prompted for the additional account name and password that you just configured:
After entering the Apache authentication, you’ll be taken to the regular phpMyAdmin authentication page to enter your other credentials. This will add an additional layer of security since phpMyAdmin has suffered from vulnerabilities in the past.
You should now have phpMyAdmin configured and ready to use on your Ubuntu 16.04 server. Using this interface, you can easily create databases, users, tables, etc., and perform the usual operations like deleting and modifying structures and data.

Add the following to the bottom of the file:
I used this tutorial for installing phpmyadmin; but didn’t work after executing all instructions in step 01 I had this error message when trying to access phpmyadmin:
After some research in the Internet I found the solution: I had to add the following instruction in /etc/apache2/apache2.conf
then restart my apache2.
I dont know what’s happend… but I cant log in phpmyadmin. I tried with user and my pass, root and pass of phpmyadmin. Display this message: #1045 - Access denied for user ‘root’@‘localhost’ (using password: YES)
Recently MySQL changed their code so that you could not leave a blank port when installing phpmyadmin so I keep getting an error when I try to install PHP my admin.
"An error occurred while installing the database:
mysql: [ERROR] mysql: Empty value for ‘port’ specified"
you should make it bigger the part where you mentioned Hit Space, Tab, and then Enter to select Apache. it’s a critical one
Thanks for this - really helpful!
Great Tutorial, it’s very clear and to the point. After I have installed phpmyadmin, when clicking on the Databases tab at the top I see No Permission, when I try to create ( New User / Database ), update or grant privileges, I get Access Denied for the user “phpmyadmin”. Turns out I should have been using the root user and the password DO creates automatically, which is found by using sudo cat /root/.digitalocean_password. Thanks to the article https://www.digitalocean.com/community/questions/mysql-root-password my 3 days of suffering has ended.
I needed to add
after installing phpmyadmin
For those of you who didn’t select apache2 in the first step, you may want to re-install.
Then start the installation process again.
I couldn’t load phpmyadmin because I didn’t select apache2 from the beginning. If there is a better way, please share.
“The installation process actually adds the phpMyAdmin Apache configuration file into the /etc/apache2/conf-enabled/ directory, where it is automatically read.”
Nope, usually he does not.
U must copy: sudo cp /etc/phpmyadmin/apache.conf /etc/apache2/conf-enabled/phpmyadmin.conf Than open it: sudo nano /etc/apache2/conf-enabled/phpmyadmin.conf Add line after “DirectoryIndex index.php”: AllowOverride All
Example: <Directory /usr/share/phpmyadmin> Options FollowSymLinks DirectoryIndex index.php AllowOverride All
