这里演示的是centos6安装mysql5.5 一下方式最后安装会出错！ 1. rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm 2. yum install libmysqlclient15 --enablerepo=webtatic 3. yum remove mysql mysql-* 4. yum install mysql55 mysql55-server --enablerepo=webtatic

这里来个centos6的安装方法

To list Old MySql

yum list installed | grep -i mysql

To remove Old MySql

yum remove mysql mysql-*

Remi Dependency on CentOS 6 and Red Hat (RHEL) 6

rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm  rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

Install MySQL server

yum --enablerepo=remi,remi-test install mysql mysql-server

如果安装不成功就继续执行以下：Download the Remi repo

cd /etc/yum.repos.d wget http://rpms.famillecollet.com/enterprise/remi.repo

Install/Update the mysql version

yum --enablerepo=remi install mysql-server

OR 站长教学网 eduyo.com

yum --enablerepo=remi update mysql-server

安装成功后查看安装列表To list New MySql

yum list installed | grep -i mysql

启动 start MySql server

/etc/init.d/mysqld start ## use restart after update

OR

service mysqld start ## use restart after update

chkconfig --levels 235 mysqld on

Last

mysql_upgrade -u root -p

Now my MySql version is 5.5.32
