mysql修改默认root用户密码

环境:从官网下载的rpm包:MySQL-server-advanced-5.6.26-1.el6.x86_64.rpmmysql

安装在Linux。sql

安装以后,链接数据库,使用命令:mysql -uroot -p数据库

有的mysql安装后默认密码为空,不用输入密码,直接回车就能够进到数据库中。进去以后再改密码,而后正常使用。spa

可是也有有密码,殊不知道密码是什么的。server

这时候就须要查看一个文件:/root/.mysql_secret。安装mysql数据库以后,密码默认写在这个文件中。blog

登陆时使用这个密码便可。ci

以下图:input


知道密码,就能够链接数据库了:it


[root@MySQL-SQL1 mysqlmedia]# mysql -u root -p
Enter password:

mysql> set password for 'root'@'localhost'=password('root');

记得链接上以后须要当即修改root用户密码才能使用的。
