关于nginx的小小笔记

不常用，没过一段时间都要去搜一下，干脆自己记下来

重启nginx服务器

/etc/init.d/nginx restart
# or
service nginx restart

在新增/修改配置之后，需要重启服务器

如果遇到问题:

[....] Restarting nginx (via systemctl): nginx.serviceJob for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.
 failed!

按照指示输入systemctl status nginx.service
