Proxmox 3.x to Proxmox 4.x

Share this
I have a very simple Proxmox setup at home. No cluster (anymore), but I did have to convert from 3.x to 4.x to keep current. This means going from OpenVZ to LXC. In reality they are very similar, but it's more or less like changing out the hood on the car (from a sysadmin perspective). The basic theory behind the conversion is not to upgrade the current machine in place, but to do a side-by-side or blue/green deployment in order to retain any information about the old guest VMs and containers as well as keep a back out plan.

Drupal Error 500 With A Correct Server Configuration in VirtualMin

Share this
This past week I migrated some sites that were originally on their own server to a cloud server running VirtualMin. After migrating the sites, everything seemed to be in place including the MySQL database, files, DNS, etc. However, I kept getting a 500 Internal Server Error when loading the site. To fix this, I had to change options in the .htaccess file for both the main site and the files directory (sites/default/files): Change Options +FollowSymLinks to # Options +FollowSymLinks Options +SymLinksIfOwnerMatch

Enabling Clean URLs for Drupal in Ubuntu 14.04 LTS

Share this

Drupal is awesome, but without clean URLs it can make site configuration and menu setup exceedingly annoying.

In the newer versions of Ubuntu, the Apache config has changed just enough to make me re-do a bunch of stuff when setting up a new Drupal install. Here is the way I was able to enable Clean URLs from a base Ubuntu 14.04 LTS LAMP install:

Installing ViMP Part 3: Installing ViMP

Share this

These steps are mostly taken from the ViMP FAQ, with modifications from where I stumbled. I had originally tried to make this one long document, but to avoid a wall of text and getting lost in the middle, I've split it out into three parts: Installing the Web Server, Installing the Transcoding Tools, and Installing ViMP.

Notes:

  • This how-to assumes that you have already installed Ubuntu Server 12.04 LTS, have SSH enabled in order to remotely manage the server, and have followed Part 1 of this tutorial
  • I prefer to use nano as my text editor, because it's stupid simple. Ctrl+W is for search, Ctrl+X is for close/save.
  • I run these commands as sudo. Use sudo su in order to drop into permanent sudo mode.

Installing the Transcoding Tools

  1. First and foremost, you'll have to download the ViMP installer and move it to your server with a program such as FileZilla. Because the download is behind a login, you won't be able to do a wget to download. I recommend putting the download in your home folder and launching the installer from there. I had problems when I uploaded it to the recommended location, /var/www/.
  2. Once ViMP is loaded on the server, make it executable:

    chmod +x vimp.framework---installer.bin

  3. Start the install script:

    ./.framework---installer.bin
