saltstack操作远程执行命令报错：“is running as PID 113257 and was started at”的解决

　　执行命令没有成功：

[root@linux-node1 base]# salt '*' state.sls web.apache

　　怀疑是虚拟机里的连接有点问题。
#测试和minion的连接，发现没有问题

　　在百度上搜索报错信息：“is running as PID 113257 and was started at”，找到一篇文档：http://blog.csdn.net/baidu_25506889/article/details/48050619——The function "state.highstate" is running as PID 4417的解决方法
　　根据文章的内容，停掉node1的salt服务：

[root@linux-node1 base]# systemctl stop salt-master
[root@linux-node1 base]# systemctl stop salt-minion
[root@linux-node1 base]# ps -ef|grep salt
root     114208 110544  0 00:03 pts/1    00:00:00 grep --color=auto salt

　　重新启动salt服务：

[root@linux-node1 base]# systemctl start salt-master
[root@linux-node1 base]# systemctl start salt-minion

　　报错信息变了：

[root@linux-node1 base]# salt '*' state.sls web.apache

　　突然领悟到可能是“linux-node1”已经运行有80端口。检查后发现，果然如此。

　　停掉之前运行的nginx服务：

[root@linux-node1 base]# systemctl stop nginx

　　这次就成功了：

[root@linux-node1 base]# salt '*' state.sls web.apache
