| + | |||
| + | Using **mdadm**, I have the following running from **/ | ||
| + | < | ||
| + | mdadm --monitor --daemonise --mail MY.EMAIL@MY.SERVER --test /dev/md0 | ||
| + | </ | ||
| ====== Daemon Configurations ====== | ====== Daemon Configurations ====== | ||
| + | ===== apcupsd ===== | ||
| + | - Download from the website the **apcupsd-3.14.4-1.el5.x86_64.rpm | ||
| + | ** package and install it: < | ||
| + | cd /root/down | ||
| + | yum localinstall apcupsd-3.14.4-1.el5.x86_64.rpm | ||
| + | </ | ||
| + | - Checked over the defaults, and they look perfect to me. The other machines in the house will use this daemon to signal whether they should turn off or not. | ||
| + | |||
| + | **NOTE:** I pulled the plug on this to test if they all at least saw the power going down. Now that I think about it, archon is going to need to go down first, so I'll need to modify the battery time left on the slave so it goes first. | ||
| + | |||
| + | Test run by pulling the plug (I saw this same message on both slaves (archon and mythtv): | ||
| + | |||
| + | Thu Nov 13 07:21:22 EST 2008 Power failure. | ||
| + | Thu Nov 13 07:21:28 EST 2008 Running on UPS batteries. | ||
| + | Thu Nov 13 07:23:15 EST 2008 Mains returned. No longer on UPS batteries. | ||
| + | Thu Nov 13 07:23:15 EST 2008 Power is back. UPS running on mains. | ||
| + | |||
| + | ===== dhcpd ===== | ||
| + | |||

| ==== Raid5 Build ==== | ==== Raid5 Build ==== | ||
| + | === My Notes Take II === | ||
| + | |||
| + | I had the old Hitachi 500gb drive that used to be my MST3k repository die, so I think I'm going to go with a clean and unencrypted raid this time around (now that I know how to do it, I'd rather have the speed). | ||
| + | |||
| + | Creation Date: --- // | ||
| + | |||
| + | - Turned off the server, and swapped out the Hitachi with the new Seagate ES.2 500gb drive. | ||
| + | - Create a partition on the new drive (just take up the entire disk) with **fdisk** on each as the primary partition. | ||
| + | - Use **mdadm** to create the array < | ||
| + | mdadm --create /dev/md0 --chunk=64 --level=5 | ||
| + | </ | ||
| + | - Format the device as ext3: < | ||
| + | mkfs.ext3 -m 0 /dev/md0 -L /space # I am not leaving any reserve since this is a data drive only | ||
| + | </ | ||
| + | - Mount the raid < | ||
| + | mount /dev/md0 / | ||

| + | ==== Update PHP ==== | ||

| + | baseurl=http:// | ||
| + | enabled=0 | ||
| + | gpgcheck=1 | ||

| + | </ | ||
| + | - Restart the webserver once PHP is installed: | ||
| + | service httpd restart | ||
| + | </ | ||
| + | |||
| + | ==== Gallery 3 Beta 2 Install ==== | ||
| + | |||
| + | - Download the .zip file | ||
| + | - I made a virtual host to: [[http:// | ||
| + | - Modified the named configuration files and added **gallery.rabine.org** | ||
| + | - Added **/ | ||
| + | - Created a directory on the raid to store all the data | ||
| + | - Had to disable SELinux (probably a rule I could have used to allow it... but I'm being lazy) for apache to see the raid drive directory!? | ||
