phpmyadmin vs EPEL

Question

I am running Centos 6.0 (Final) , the i386 version.

I am trying my hardest to get a decent LAMP Server running, with phpMyAdmin.

I can get everything installed just fine, MySQL, Apache2 (httpd), PHP 5.x, etc..., but when I get to reading some tutorials on installing phpMyAdmin, I fail miserably. Each tutorial I read mentions enabling the EPEL/REMI repo.. As soon as I add this repo I am not able to use yum anymore.

I continue to get this error message

[root@username tmp]# yum update

It's driving me insane. I am using a VPS so everytime this happens I am easily able to restart from scratch, but after so many times with the same results I have no clue where I am going wrong.

Answer 1

Your (very small, and probably crappy OpenVZ) VPS has run out of memory.

You can try working around this by disabling the (probably strictly unnecessary) yum plugins, to reduce the memory usage:

yum --disableplugin=* update

If that doesn't get you any farther, you'll have to stop some services to free up memory.

If you still can't get anywhere, you'll have to upgrade your VPS package.
