Centos安装mysql

一、检查系统是否安装老版本，有的话干掉

#yum list installed | grep mysql
mysql-libs.x86_64      5.1.73-5.el6_6   @anaconda-CentOS-201508042137.x86_64/6.7


// 卸载某一个
#yum -y remove mysql-libs.x86_64

二、安装及配置

# wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm
# rpm -ivh mysql-community-release-el6-5.noarch.rpm
# yum install mysql-community-server -y

检查MySQL状态

service mysqld status

开启MySQL服务

service mysqld start 

重启MySQL服务

# service mysqld restart

设置为开机启动

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

设置MySQL密码，第一次登陆不需要密码回车进入；设置本机MySQL密码及远程登录密码：

# mysql; 
mysql> use mysql;
mysql> update user set password=password(\'你设置的密码\') where user=\'root\' and host=\'localhost\';  
mysql> GRANT ALL PRIVILEGES ON *.* TO \'root\'@\'%\' IDENTIFIED BY \'你设置的密码\' WITH GRANT OPTION;
mysql> flush privileges;
mysql> quit
