03_已解决 [salt.master :2195][ERROR ][6219] Failed to allocate a jid. The requested returner 'mysql' could not be loaded.

总结：

对于python2.7环境下的salt来说，要安装pip install mysql-python

对于python3环境下的salt来说，pip install mysqlclient的时候要和salt在同一个目录下

1、生产环境3.6的，这个怎么整呢

1、2019.2 的salt

3、原因：

又是提示我，未加载mysqlpy，这次我是真的装了

mysql环境也是3.6的。

salt也是3.6的

难道是 位置不在一起？？？

4、解决1：

卸载重装

[root@IP ~]# pip3 uninstall mysqlclient
[root@IP salt]# pip3 install  mysql-client

依旧问题存在

5、解决2：完成

也许真的是没在一个目录

pip安装指定目录  https://blog.csdn.net/guotong1988/article/details/61196363

[root@IP salt]# pip3 install --target=/usr/lib/python3.6/site-packages/ mysql-client

6、结果：成了
