从别人哪儿考到的mysql安装过程

Step1: 检测系统是否自带安装mysql

# yum list installed | grep mysql
Step2: 删除系统自带的mysql及其依赖
命令：

# yum -y remove mysql-libs.x86_64
Step3: 给CentOS添加rpm源，而且选择较新的源
命令：

# wget dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm
# yum localinstall mysql-community-release-el6-5.noarch.rpm
# yum repolist all | grep mysql
# yum-config-manager --disable mysql55-community
# yum-config-manager --disable mysql56-community
# yum-config-manager --enable mysql57-community-dmr
# yum repolist enabled | grep mysql
Step4:安装mysql 服务器
命令：

# yum install mysql-community-server
Step5: 启动mysql
命令:

# service mysqld start
Step6: 查看mysql是否自启动,而且设置开启自启动
命令:

# chkconfig --list | grep mysqld
# chkconfig mysqld on
