centos 7 mysql 安装

CentOS 7的yum源中貌似没有正常安装mysql时的mysql-sever文件，需要去官网上下载
 
# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
# rpm -ivh mysql-community-release-el7-5.noarch.rpm
# yum install mysql-community-server
成功安装之后重启mysql服务
 
# service mysqld restart
初次安装mysql是root账户是没有密码的
设置密码的方法
 
# mysql -uroot
mysql> set password for ‘root’@‘localhost’ = password('mypasswd');


mysql> grant all privileges on *.* to 'root'@'%' with grant option;
Query OK, 0 rows affected (0.00 sec)


mysql> flush privileges;


mysql> exit




搞定！
