ELK学习遇到的问题4--Job for nginx.service failed because the control process exited with error code....

遇到的问题：

[root@m01 modules.d]# systemctl start nginx
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.
原因是开启的端口和docker容器里的端口重复了

解决方法：

[root@m01 modules.d]# systemctl stop docker
[root@m01 modules.d]# systemctl disable docker
[root@m01 modules.d]# iptables -F
[root@m01 modules.d]# iptables -X
[root@m01 modules.d]# iptables -Z
[root@m01 modules.d]# iptables -nL
