【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

将之前备份的my.conf配置文件放到/etc/my.conf
service mysqld start

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)
