Hello.

First of all sorry for my english. I’m a beginner of Percona and Linux administration, and i’ve a problem with upgrade.  
This is the situation.  
VPS with WHM 11.30, php 5.3.8, litespeed and Mysql 5.1.

The upgrade from Mysql 5.1 to Percona 5.1 works great.  
Now i’m trying to remove Percona 5.1 with:

rpm -qa | grep Percona-Server | xargs rpm -e --nodeps

then install 5.5 with:

yum install Percona-Server-server-55 Percona-Server-client-55

and the last step

/usr/sbin/mysqld --skip-grant-tables --user=mysql &

Then CTRL + C, mysql\_upgrade, killall /usr/sbin/mysqld and /sbin/service mysql start.

The problem is that litespeed says: error 503.

My question is: do I need to compile php and apache with Easyapache again?

Thanks for the help 🙂

Nicola
