02_已解决 [salt.minion :1758][ERROR ][52886] Returner mysql.returner could not be loaded: 'mysql' __virtual__ returned False: Could not import mysql returner; mysql python client is not installed.

总结：python2.7下的salt，要把 mysql-python也安装，并不是python3环境，看清，看清

Returners组件，master自动把值写入mysql数据库中，出现的问题

提示我未安装pymsql，但是我记得我安装l

3、原因：

用到的命令

# 查找文件
比如我要查看elasticsearch安装在哪了:
# sudo find / -name elasticsearch -type d

难道是我的pymsql装错地方了

　　python第三方包位置

　　pymysql位置

位置不一样，会影响吗？  （很重要，欲哭无泪）

salt位置。怎么是2.7的，难道说。。。

查看return.py源码位置

就是这样的

4、解决掉它

现在本地python2.7装mysqlpy测试

[root@localhost ~]# pip2 install mysql-python

重新来一次配置master ok

哈哈哈哈哈
