安装mysql 5.6

检查系统是否自带安装mysql

[[email protected] ~]# yum list installed | grep mysql 
mysql.x86_64            5.1.73-5.el6_6  @anaconda-CentOS-201508042137.x86_64/6.7
mysql-devel.x86_64      5.1.73-5.el6_6  @anaconda-CentOS-201508042137.x86_64/6.7
mysql-libs.x86_64       5.1.73-5.el6_6  @anaconda-CentOS-201508042137.x86_64/6.7

发现有系统自带mysql，将其删除

[[email protected] ~]#  yum -y remove mysql-libs.x86_64 

删除后可以再次检查是否还存在mysql

由于mysql的yum源服务器在国外，所以下载速度会比较慢，还好mysql5.6只有79M大，而mysql5.7就有182M了，所以这里想安装mysql5.6

[[email protected] ~]# wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm

解压rpm 包（这个rpm还不是mysql的安装文件，只是两个yum源文件，执行后，在/etc/yum.repos.d/ 这个目录下多出mysql-community-source.repo和mysql-community.repo ）

[[email protected] ~]# rpm -ivh mysql-community-release-el6-5.noarch.rpm 

用yum repolist mysql这个命令查看一下是否已经有mysql可安装文件 

[[email protected] ~]# yum repolist all | grep mysql

mysql-connectors-community-source MySQL Connectors Community - S disabled

安装mysql 服务器

[[email protected] ~]# yum install -y mysql-community-server
