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@H_404_1@

成功安装之后重启MysqL服务@H_404_1@

初次安装MysqL是root账户是没有密码的@H_404_1@

设置密码的方法@H_404_1@

# MysqL -uroot@H_404_1@

MysqL> set password for ‘root’@‘localhost’ = password('mypasswd');@H_404_1@

MysqL> exit@H_404_1@

搞定！@H_404_1@

@H_404_1@

远程授权连接MysqL@H_404_1@

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;@H_404_1@

FLUSH PRIVILEGES;@H_404_1@
