Upgrading mysql questions (CentOS)

[Noturns]

I have Plesk 12 on Centos 6.6 with MySQL version 5.1.x and i'm considering to update our MySQL core to 5.5 or higher. However the Mysql APT repository supports the following Linux Distros:

Debian - 7
Ubuntu - 12.04 LTS
Ubuntu - 14.04 LTS
Ubuntu - 14.10

Has someone found yum equivalents of apt repositories for CentOS ?

Another question. In the plesk dashboard in Tools & Settings > Database Servers
there you can add Local MySQL Servers. (link to Parallels Plesk manual)

After i have upgraded my CentOS would i still be able to assign or switch to different Mysql versions within Plesk?

Last question are the Local MySQL Servers within Plesk always bases on the Linux MySQL version?

Looking forward in someone their reply

Checking if mysql is already installed...

# rpm -q mysql-server
mysql-server-5.1.73-3.el6_5.x86_64

When i do the following command this is the reply i get

# sudo yum localinstall mysql-community-release-el6-5.noarch.rpm
Loaded plugins: fastestmirror, security
Setting up Local Package Process
Cannot open: mysql-community-release-el6-5.noarch.rpm. Skipping.
Nothing to do

Hmmm... What about using this Atomic method - https://www.atomicorp.com/wiki/index.php/Mysql ?

I first tried the official mysql upgrade and this resulted crashing the mysqld service.

Second attemt installed the Atomic method and this also resulted in crashing the mysqld service. -- Thanks any way for the Atomic suggestion as i never heard of that company

# /etc/init.d/mysqld restart
Stopping mysqld: [ OK ]
MySQL Daemon failed to start.
Starting mysqld: [FAILED]

tail /var/log/mysqld.log

It's a pitty i cant read out the InnoDB events.
I will try the official mysql one more time maybe i looked over something
