Although installations of Proxmox usually go smoothly, sometimes you may have problems detecting storage arrays or other hardware. By default the installer doesn’t give much away about any problems, so in the event of a problem you need to enable debugging.

To enable debugging, you will need to type debug at the installation boot menu.

Proxmox boot install screen debug

You can mix this with other arguments to over ride the defaults. See Advanced install settings for more information.

You will then be taken to a console where you can run any pre diagnostic commands. Press CTRL + D to continue the installation once you have finished with the terminal. If the installer errors, click Abort to return to a console.

proxmox logo gradInstalling Proxmox is quick and easy – the installer GUI takes care of everything, such as installing the correct packages and partitioning the root hard disk.

You can download Proxmox from the Proxmox download page as an ISO which you will need to boot your server from.

See my  Install guide blog post for the basics on installing Proxmox.

On more advanced installs, there may be a need to override some of these options. For example, you may want to specify how much swap space is created, or the size of the root partition. On one of my installs using a 120GB disk as the install device, 28GB is used for my root (/) partition on a default install. As I only run the basic, required packages on the host this size is far too large. With larger disks the problem gets worse.

When installing proxmox, the first screen of the installer is the Boot menu. At this prompt, we can specify arguments to override the defaults.

Proxmox boot install screen

The above example linux ext4 maxroot=10 swapsize=20 sets the partition format to ext4 (ext3 is the default), creates a root partition of 10GB providing the disk is large enough and swapsize of 20GB.

The options available at the boot menu are:

  • linux ext4 – sets the partition format to ext4. The default is ext3.
  • hdsize=nGB – this sets the total amount of hard disk to use for the Proxmox installation. This should be smaller than your disk size.
  • maxroot=nGB – sets the maximum size to use for the root partition. This is the max size so if the disk is too small, the partition may be smaller than this.
  • swapsize=nGB – sets the swap partition size in gigabytes.
  • maxvz-nGB – sets the maximum size in gigabytes that the data partition will be. Again, this is similar to maxroot and the final partition size may be smaller.
  • minfree=nGB – sets the amount of free space to remain on the disk after the Proxmox instillation.

proxmox_logoVersion 1.x of Proxmox VE is now end of life. This means that Proxmox will no longer be supported, bugs will not be fixed and security fixes will not be released. You will still receive the standard rift of Debian 6 patches and updates from the Debian repositories.

If you are still on version 1.x of Proxmox VE you should upgrade to Proxmox 2.2 as soon as possible. See the official Proxmox wiki on upgrading.

http://pve.proxmox.com/wiki/Upgrade_from_1.9_to_2.0

See our blog post on installing Proxmox 2 – Yes, I know it’s version 2.1 but, the steps are the same for Proxmox 2.2.

OpenSearchServer is an open source website crawler and query engine to provide advanced search capabilities to your website.

Onced you have installed OpenSearchServer you simply add an index, specify a URL to begin crawling and you website will be indexed and available to search.

WordPress has a pluginwhich integrates OpenSearchServer and replaces the existing search box to serve search queries directly to your OpenSearchServer instance. The pluginsite is available here.

Configure OpenSearchServer Search plugin

Login to your WordPress admin site and click Add New under Plugins. Search for opensearchserver and click Install Now.

Once you have the plugin installed, click Activate to enable the plugin.

You will then need to configure the OpenSearchServer plugin. The configuration page is under Plugins, then OpenSearchServer. Under Instance settings fill in your OpenSearchServer details.

  • : is the URL which points to your OpenSearchServer installation. Example: http://search.jamescoyle.net:8080/
  • : The index name you created on your OpenSearchServer to hold the search database for your WordPress site.
  • : Authentication username for your OpenSearchServer.
  • : Authentication API key for your OpenSearchServer.
Click Update Settings once you have entered the details.

For better search results, I would recommend using the following code under :

title:($$)^10 OR title:("$$")^10 OR
titleExact:($$)^10 OR titleExact:("$$")^10 OR
titlePhonetic:($$)^10 OR titlePhonetic:("$$")^10 OR
url:($$)^5 OR url:("$$")^5 OR
urlSplit:($$)^5 OR urlSplit:("$$")^5 OR
urlExact:($$)^5 OR urlExact:("$$")^5 OR
urlPhonetic:($$)^5 OR urlPhonetic:("$$")^5 OR
content:($$) OR content:("$$") OR
contentExact:($$) OR contentExact:("$$") OR
contentPhonetic:($$) OR contentPhonetic:("$$")

Click Update Options once you have finished.

Your Search box is replaced as soon as you activate the OpenSearchServer plugin. You will need to make sure your Search box is available on your site.

Your search queries will now be served from your local search server!
