MYSQL5.6版本详细安装步骤

1、查看系统中是否自带安装mysql

yum list installed | grep mysql

2、删除系统自带的mysql及其依赖（防止冲突）

yum -y remove mysql-libs.x86_64

wget dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm

5、安装下载好的rpm文件

 yum install mysql-community-release-el6-5.noarch.rpm -y

6、安装成功之后，会在/etc/yum.repos.d/文件夹下增加两个文件

cd /etc/yum.repos.d/

7、修改mysql-community.repo文件

vi mysql-community.repo
//修改配置文件
