I think we need streaming thing for running code from languages other than Java, but it is not present in this hadoop installation. I don’t know what actually the problem is ?
I've installed Wordpress a couple of servers following your best practice tutorials on here. I've got my sites running and now want to secure them. Specifically, I'm trying to hide the Wordpress Admin URL. However, I've tried all kinds of plugins and even modifying the .htaccess directly but nothing work. It hides the wp-admin page but won't redirect to new URL?
I've been trying to set up a WordPress site using these tutorials: [How To Set Up a Host Name](https://www.digitalocean.com/community/tutorials/how-to-set-up-a-host-name-with-digitalocean) [Initial Server Setup](https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-16-04) [How to Install LAMP stack](https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu-16-04) [How to Set Up Apache Virtual Hosts](https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-virtual-hosts-on-ubuntu-16-04) I've completed each tutorial without any error messages and I've restarted the process on multiple droplets, but every time I enter my domain Firefox displays "Unable to connect". I've added the proper exceptions in UFW (allowing traffic on ports 80 and 443, restarting Apache after each change). My ports.conf file confirms ports 80 and 443 are being listened to as well. It might also be worth noting that earlier, before this problem arose, I had the virtual host working, had the site secured via Let's Encrypt, and had WordPress installed. After some frustration in trying to get to the WordPress admin page, I ended up starting from scratch. Any help is appreciated.
I set up an Ubuntu 16.04 droplet to host my client's website (let's call it clientwebsite.com). I also helped him set up G Suite email hosting for his new business email (let's call it client@clientwebsite.com). In his G Suite settings, we set up a catch all so that all emails to @clientwebsite.com addresses are forwarded to client@clientwebsite.com. The Ubuntu server uses exim4 to send emails. I *thought* I configured it to send all server-related emails to me (let's call me developer@studio.com). I ran ```sudo dpkg-reconfigure exim4-config``` which resulted in a ```/etc/exim4/update-exim4.conf.conf``` file like this: ``` dc_eximconfig_configtype='internet' dc_other_hostnames='clientwebsite.clientwebsite.com; clientwebsite; localhost.localdomain; localhost' dc_local_interfaces='127.0.0.1' dc_readhost='' dc_relay_domains='' dc_minimaldns='false' dc_relay_nets='' dc_smarthost='' CFILEMODE='644' dc_use_split_config='false' dc_hide_mailname='' dc_mailname_in_oh='true' dc_localdelivery='mail_spool' ``` And I edited the ```/etc/aliases``` file to look like this: ``` mailer-daemon: developer@studio.com postmaster: developer@studio.com nobody: developer@studio.com hostmaster: developer@studio.com usenet: developer@studio.com news: developer@studio.com webmaster: developer@studio.com www: developer@studio.com ftp: developer@studio.com abuse: developer@studio.com noc: developer@studio.com security: developer@studio.com root: developer@studio.com jessica: developer@studio.com monit: developer@studio.com ``` Then ran the ```newaliases``` command and restarted exim4 with ```sudo service exim4 restart```. All root emails are ending up in my client's inbox (client@clientwebsite.com), due to the catch all we set up in G Suite. I expected the server to read the ```/etc/aliases``` file and send them to me (developer@studio.com) instead... but it seems this file is being completely ignored! How can I make sure all server-related emails are sent to me instead of my client? Thanks!
Hi everyone, I could use a little advise regarding running multiple Wordpress sites on a single server, as multiple users, and making sure the webserver has the proper permissions to make changes while making sure security is in order. *What I like to achieve...* A configuration in which I can use a user per website, and where the webserver can make changes (i.e. uploading media, plugins, etc), without relying on chmod (not having to use chmod at all feels better). Where the user can make changes to it's directory (e.g. a git working directory for automatic deployments). When the users can't change each other files. *I wonder...* Is the configuration described below a proper one? Should I do something differently? Are there better solutions? *Some backstory...* For a while now I have been setting up servers for websites and web apps. Most of the time I run multiple websites from the same server. Could be a staging and production environment, but also different (client) websites. Sometimes I add CI to the mix using CircleCI. Basically CircleCI pushes to a repository on the server, this repo then updates the working directory which could be a web app or Wordpress theme. Everything currently works okay, although I think security, and how things are set up, could be improved. Currently my configuration often looks like... **Users** ``` somewebsite # User on the server with the directory `/var/www/somewebsite` someotherwebsite # Another user on the server with the directory `/var/www/someotherwebsite` ``` When needed I use these users to make changes to the contents. **Directories** ``` /var/www/somewebsite/html # Wordpress website /var/www/somewebsite/somewebsite.git # Git repo with a working dir set to `/var/www/somewebsite/html/wp-content/themes/sometheme` /var/www/someotherwebsite/html # Some other website /var/www/yetanotherwebsite/html # Yet another Wordpress website ``` **Permissions** The contents of `/var/www/somewebsite/html`, `/var/www/someotherwebsite/html`, and `/var/www/yetanotherwebsite/html` belong to the user and group `www-data`. Although, when I would upload something manually later, this upload (logically) belongs to the user I am using for access (not `www-data`). The users `somewebsite`, `someotherwebsite`, and `yetanotherwebsite` have been added to the `www-data` group. I believe this means `someotherwebsite` could make changes to `somewebsite` (and vice versa). Which would be better if it couldn't. **Trivia** * Depending on the requirements I use Apache or nginx. * SSH keys are used for authentication, Password Authentication is disabled. I understand my current configuration isn't the most straightforward one. I do hope I clarified the most of it. I read a lot of information regarding the subject. But It's hard to find something which is applicable to my situation. This tutorial was very useful https://www.digitalocean.com/community/tutorials/how-to-set-up-multiple-wordpress-sites-on-a-single-ubuntu-vps. Any tips, feedback and insights are welcome!
