今天在服务器中安装好了一个mysql服务器了,起初是配置好的mysql的root密码了,但经过一些软件的优化之后把root密码改成了空了,因为刚安装好的环境没有像mysql管理工具了,所以只有在命令模式下使用mysqladmin进行修改了,下面111cn站长为各位介绍一下mysql命令模式修改mysql root密码方法。

修改mysql密码过程如下

百度搜索一文章看到使用

格式:mysqladmin -u用户名 -p旧密码 password 新密码

修改于时我下看操作

Enter password:

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

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> mysqladmin -u root password 我要设置的密码
    ->
    -> ;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near 'mysql
admin -u root password 我要设置的密码' at line 1
mysql> mysqladmin -u root -password 我要设置的密码
    -> ;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near 'mysql
admin -u root -password 我要设置的密码' at line 1

最后小编使用了 mysqladmin -u root -password 我要设置的密码 无法搞定,突然想到直接更新表即可。

mysql> update mysql.user set password=PASSWORD('我要设置的密码') where User ='root
';
Query OK, 3 rows affected (0.05 sec)
Rows matched: 3  Changed: 3  Warnings: 0

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

mysql>

好了这样就搞定了哦,虽然过程不复杂也不简单。
