mysql-5.7.12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> exit

 

搞定！
