问题
salt-master 执行返回到mysql存储，安装mysql-python 发现yum install MYSQL-python 已经安装
但是执行会报错，如下

[ERROR ] Message timed out
Salt request timed out. The master is not responding. You may need to run your command with --async in order to bypass the congested event bus. With --async, the CLI tool will print the job id (jid) and exit immediately without listening for responses. You can then use salt-run jobs.lookup_jid to look up the results of the job in the job cache later.

  百度谷歌一大堆，好久都没发现。最后无意中发现一个，https://www.cnblogs.com/venicid/p/11958498.html
  废话不多说直接搞，两步搞定

  pip3 install --target=/usr/lib/python3.6/site-packages/ mysqlclient
  systemctl  restart salt-master
