【备份配置文件】 CentOS 6.5 默认yum只能安装mysql 5.1
安装前要检查机器原来是否安装过mysql，如有安装需要先进行数据备份、清理。
[root@snails ~]# yum list installed | grep mysql
[root@snails ~]# ps -ef|grep mysql
[root@snails ~]# service mysqld stop
[root@snails ~]# rpm -e mysql-libs --nodeps
[root@snails ~]# yum -y remove mysql mysql-*
设置安装源
[root@snails ~]# wget http://repo.mysql.com/mysql57-community-release-el6-8.noarch.rpm
[root@snails ~]# rpm -ivh mysql57-community-release-el6-.noarch.rpm
[root@snails ~]# ls - /etc/yum.repos.d/mysql-community*
[root@snails ~]# yum repolist all | grep mysql
[root@snails ~]# vi /etc/yum.repos.d/mysql-community.repo
### 将[mysql56-community]的enabled设置为１,[mysql57-community]的enabled设置为0 ###
[root@snails ~]# yum repolist enabled | grep mysql
mysql-connectors-community MySQL Connectors Community
mysql-tools-community MySQL Tools Community
mysql56-community MySQL 5.6 Community Server
注意:
如果不使用5. 或者其他任何版本，只能有一个是 enabled=1的，其他的都得enabled=。
安装MySQL
[root@snails ~]# yum -y install mysql-server mysql
安装完之后直接启动
将之前备份的my.conf配置文件放到/etc/my.conf
service mysqld start
之后分配用户名密码：
mysql> grant all privileges on *.* to daily@'%' identified by 'xxx';
Query OK, rows affected (0.00 sec) mysql> flush privileges;
Query OK, rows affected (0.00 sec)
