MySQL创建修改登录密码

MySQL创建修改登录密码

MySQL安装完成后,默认情况下,管理员账号root是无密码的,这个必须要设置。

1、MySQL创建密码:

[root@web01 mysql]# mysqladmin -u root password 'ceshi123'   #为mysql设置密码

[root@web01 mysql]# mysql  #直接使用mysq 登录,会报错

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

[root@web01 mysql]# mysql -uroot -pceshi123  #设置密码后的正确登录方式

Welcome to the MySQL monitor.  Commands end with ; or \g.

Your MySQL connection id is 5

2、修改密码:

[root@web01 mysql]# mysqladmin -uroot -pceshi123 password 123456

3、删除配置密码的命令:

history -c 或者 history -d n  #n为指定编号的命令
