You have finished Part 2 - Installing the necessary apps , congratulations! You are now a Linux expert, all the hard work is done. All that is left is to set up your various services.
You have finished Read first: Creating an infinite Plex server using a VPS and Cloud service . That means you have a fresh new Debian or Ubuntu installation and can access your VPS using PuTTY or its equivalent on your OS.
Now that you finished Part 4 - Restoring Rclone and Plexdrive configuration , all that is needed is restore the Plex database - and you won't even notice your server has changed.
You have prepared your backup script in Part 1 - How to restore your VPS in minutes , and your two backups (Plex database and VPS settings) are safely stored in the (Google) cloud.
If you are anything like me, you like to play with your VPS. Perhaps you like to reinstall it occasionally, or change to a new provider, or repair a corrupted server. I personally reinstall my VPS so often, that I can follow the guide almost blindly and be back to the original state in less than an hour.
You finished Part 4 - Installing Wordpress and you have your website, but it's not as safe as it should be - potential hackers could intercept your data.
Now that you finished Part 3 - Prerequisites to setup your domain , you have a working website and sub domain, each with a page you created on your own. But you want more than just a welcome message, right?
You made it up to here, you finished Part 4 - Setting up Rclone and/or Plexdrive and are still with it, congratulations! The hardest parts are done, it'll be downhill from now on. Promise!
Finished Part 2 - Configuring Ubuntu ? Then you can proceed with the installation of Plex itself. Thanks to an awesome script that is available for free, this is going to be a breeze.
