Невозможно установить сервер MySQL на CentOS 6.6

Я пробовал эту следующую команду

[root@n yum.repos.d]# rpm -qa | grep mysql  
mysql-libs-5.1.73-3.el6_5.x86_64  
mysql-community-release-fc21-5.noarch  
[root@n yum.repos.d]# 

Но я даю следующую команду

[root@n yum.repos.d]# yum remove mysql   
Setting up Remove Process   
No Match for argument: mysql       
Package(s) mysql available, but not installed.      
No Packages marked for removal        
[root@n yum.repos.d]#

Я попытался установить mysql, но он показывает следующую ошибку

[root@n yum.repos.d]# rpm -ivh http://repo.mysql.com/mysql-community-release-el5-5.noarch.rpm
