MySQL MHA /usr/share/perl5/vendor_perl/MHA/ServerManager.pm, ln301] install

在公司随便找3台测试机搭个MHA，下面这个问题折腾了三天，之前没遇到过，查了OS版本发现一致，可能是不同人弄的OS吧，知道是cpan的问题就是搞不定，郁闷。。。

MySQL Replication Health is NOT OK!

参考下面帖子发现结果还有异常
https://www.cnblogs.com/fangyuan303687320/p/9475279.html

yum install -y cpan
cpan -D DBI
# [yes---sudo]
--上面这不执行了好几分钟，输入了很多次yes
cpan DBD::mysql
还是出现下面的异常

--异常

最后发现需要先执行下这个才可以，需要回答几次yes

database user 'root' can connect to your MySQL server
and has the proper privileges that these tests require such
as 'drop table', 'create table', 'drop procedure', 'create procedure'
as well as others.

mysql> grant all privileges on test.* to 'root'@'localhost' identified by 's3kr1t';

You can also optionally set the user to run 'make test' with:
