通过mysql_config_editor设置了登录信息后，在用mysql命令登录数据库时就可以只用加一个--login-path=name的参数，

而不用再输入host,user,password等信息登陆。

举例如下:

正常登陆为:

# mysql -uroot -p'123456' --socket=/tmp/mysql.sock

配置config_editor:

#mysql_config_editor set --login-path=9527 --socket=/tmp/mysql.sock --user=root --password

Enter password:      --此时输入123456

 

打印config_editor信息:

#mysql_config_editor print --all

[9527]

user = root

password = *****

socket = /tmp/mysql.sock

用mysql --login-path登陆:

#mysql --login-path=9527
