mysql_config_editor是一种存储mysql登录信息的工具。
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
