salt minion 启动问题
Q & A：
修改minion 的配置文件中master 的值后，启动报错，如下：
Traceback (most recent call last):
File "/usr/lib/python2.6/site-packages/salt/scripts.py", line 81, in minion_process
minion.start()
File "/usr/lib/python2.6/site-packages/salt/cli/daemons.py", line 277, in start

self.future, lambda f: self.run())
File "/usr/lib64/python2.6/site-packages/tornado/gen.py", line 879, in run
yielded = self.gen.send(value)
File "/usr/lib/python2.6/site-packages/salt/crypt.py", line 553, in sign_in
raise SaltSystemExit('Invalid master key')
SaltSystemExit: Invalid master key
引起原因
认证key的错误造成。
解决方案：
1、删除
/etc/salt/pki目录，2、重启 minion，在master端认证即可。
