or

Code: Select all

service mysqld restart

MySQL Daemon failed to start.

here is the result of rpm -qa mysql\* | sort

Code: Select all

rpm -qa mysql\* | sort
mysql-5.1.58-jason.1
mysql-server-5.1.58-jason.1

i got this error when i tried to upgrade mysql apparently i using mixed versions... I am unable to show error logs i don't know if i am doing something wrong or logs have been removed...

You've installed a non-CentOS copy of mysql from the "utterramblings" repo. Uninstall it and use the CentOS supplied version.
CentOS 5 died in March 2017 - migrate NOW!
CentOS 6 goes EOL sooner rather than later, get upgrading!

I'm afraid that kloxo is completely unsupported here. It makes so many changes to the underlying operating system that any advice we might offer that would apply to a CentOS system might break one with kloxo installed more than it already is.

In addition, I have looked at kloxo in the past and found that it is not something that I would have within 1000 miles of any of my servers.

Actually you are right about kloxo... but my only option is to repair it :(

On a system without kloxo you would remove or disable the utterramblings repo by either removing the rpm that installed it or by editing the /etc/yum.repos.d file for it and flipping enabled=1 to 0. Then once that was done you'd make sure that mysqld was stopped and then yum downgrade mysql\* - probably having backed up the contents of /var/lib/mysql beforehand!

You sure you have CentOS 5? The yum downgrade command should be available on CentOS 5 and it needs a package name or pattern that matches multiple packages passed to it - so for example, yum downgrade mysql mysql-server

Well, you have not actually shown us a yum run or the output of 'uname -a'.
Also show the output of 'grep -R exclude /etc/yum*'
