CentOS 7下安装MySQL

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！

远程授权连接mysql

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

FLUSH  PRIVILEGES;
