mysql config editor_mysql_config_editor
mysql_config_editor是MySQL5.6.6中引入的，在5.6.10中正式GA。
借助mysql_config_editor工具将登陆MySQL服务的认证信息加密保存在.mylogin.cnf文件(默认位于用户主目录) 。之后，MySQL客户端工具可通过读取该加密文件连接MySQL，避免重复输入登录信息，避免敏感信息暴露。
.mylogin.cnf和默认的my.cnf文件不同，是不能像my.cnf直接查看其中的加密内容的。

3.创建一个login-path/profile

其中--login-path表示指定通过mysql客户端登录时的标识
创建结束就可以在用户主目录下看到该profile文件了：
# ls -a ~ |grep cnf
.mylogin.cnf
可以根据需要创建多个登陆profile
# mysql_config_editor set --login-path=abce1 --user=root -p
# mysql_config_editor set --login-path=abce2 --user=root -p
4.使用profile登陆
# mysql --login-path=abce

5.查看所有的login-path/profiles
# mysql_config_editor print --all
[abce]
user = root
password = *****
[abce1]
user = root
password = *****
[abce2]
user = root
password = *****
6.移除一个login-path/profile
# mysql_config_editor remove --login-path=abce2
# mysql_config_editor print --all
[abce]
user = root
password = *****
[abce1]
user = root
password = *****
也可以某个login-path中的部分信息，比如：
# mysql_config_editor set --login-path=abce3 --host=localhost
# mysql_config_editor print --all
[abce]
user = root
password = *****
[abce1]
user = root
password = *****
[abce3]
host = localhost
# mysql_config_editor remove --login-path=abce3 --host
# mysql_config_editor print --all
[abce]
user = root
password = *****
[abce1]
user = root
password = *****
[abce3]
