| [[Image:an-cdb-splash.png|right|thumb|300px|AN!CDB - Cluster Dashboard]] | |
| | |
| This mini tutorial will show you how to install [[AN!CDB]]; The ''AN! Cluster Dashboard''.
| |
| | |
| The easiest way to setup ''AN!CDB'' is to use the <span class="code">[https://alteeve.ca/files/an-cdb-install.sh an-cdb-install.sh]</span> script.
| |
| | |
| Install [[CentOS]] or [[RHEL]] version 6 on your dashboard server. Configure the network interfaces so that the dashboard can connect to the [[IFN]] and [[BCN]].
| |
| | |
| Once the network is setup and the install is complete, download this file;
| |
| | |
| * <span class="code">[https://alteeve.ca/files/an-cdb-install.sh https://alteeve.ca/files/an-cdb-install.sh]</span>
| |
| | |
| <syntaxhighlight lang="bash">
| |
| curl -O https://alteeve.ca/files/an-cdb-install.sh
| |
| chmod 755 an-cdb-install.sh
| |
| # | |
| </syntaxhighlight>

| |
| </syntaxhighlight>
| |
| | |
| Once you have save the install script, edit it with your favourite text editor and change the following;
| |
| | |
| <syntaxhighlight lang="bash">
| |
| vi an-cdb-install.sh
| |
| </syntaxhighlight>
| |
| <syntaxhighlight lang="bash">
| |
| # Change the following variables to suit your setup.
| |
| PASSWORD="secret"
| |
| HOSTNAME="an-m03.alteeve.ca"
| |
| CUSTOMER="Alteeve's Niche!"
| |
| </syntaxhighlight>
| |
| | |
| Once the changes are saved, run the script. It could take quite a while to complete depending on how slow your dashboard machine is, how slow your internet connection is and how much needs to be downloaded.
| |
| | |
| <syntaxhighlight lang="bash">
| |
| ./an-cdb-install.sh
| |
| </syntaxhighlight>
| |
| <syntaxhighlight lang="text">

| # #
| |
| # Dashboard install is complete. #
| |
| # #
| |
| # When you reboot and log in, you should see a file called: #
| |
| # [public_keys.txt] on the desktop. Copy the contents of that file and add #
| |
| # them to: [/root/.ssh/authorized_keys] on each cluster node you wish this #
| |
| # dashboard to access. #
| |
| # #
| |
| # Once the keys are added, switch to the: [apache] user and use ssh to #
| |
| # connect to each node for the first time. This is needed to add the node's #
| |
| # SSH fingerprint to the apache user's: [~/.ssh/known_hosts] file. You only #
| |
| # need to do this once per node. #
| |
| # #
| |
| # Please reboot to ensure the latest kernel is being used. #
| |
| # #
| |
| # Remember to update: [/var/www/home/ricci_pw.txt] and: [/etc/an/an.conf]!! #
| |

| | |
| generally, this will update the kernel and/or install the graphical desktop. Generally you will want to reboot at this point.
| |
| | |
| As it says above, remember to edit the <span class="code">/var/www/home/ricci_pw.txt</span> and <span class="code">/etc/an/an.conf</span> files to add the information for the Anvil!s you want this dashboard to have access to.
| |
| | |
| Also remember to log into the <span class="code">apache</span> user's terminal and [[SSH]] to each node. This will ask you to verify the node's fingerprint and then record it in the <span class="code">apache</span> user's <span class="code">/var/www/home/.ssh/known_hosts</span> file. The dashboard '''will not connect''' to a node until this is done.
