How to install the RHEV (Red Hat Enterprise Virtualisation) agent on a RHEL 6 server.
These instructions will provide a fully functional suPHP installation on CentOS 6.
With my new CentOS 6 web server I’ve decided I want to leave SELinux switched on if I can get everything configured correctly. In the past I’ve always switched it off but a little extra protection is always preferable.
Many times I’ve gone to hit CTRL-K, S in a JOE session to save changes to a file but missed the “K” meaning I actually sent CTRL-S to the terminal which sends a “stop flow” signal.
Both my network monitoring servers suffered this condition over the 2wks my company takes holidays for Christmas so I returned to work to find 2 VMs consuming 6ghz of CPU between them. A quick check of top showed mysqld_safe consuming 100% CPU on both VMs for no apparent reason.
I extracted a tarball which had applied 777 (rwx) permissions to all files and directories that it contained. I wanted to set all files to 644 and all directories to 755, but there were too many levels to do it manually so I needed to do it through a shell script.
After upgrading a CentOS 5.5 Hyper-V VM to CentOS 5.9 (or RHEL 5.5 to RHEL 5.9 / 5.10) you get a kernel panic when booting with the new kernel. If you select the old kernel from the GRUB menu, the server boots as expected.
