停止操作

[root@ta30-53 nginx]# ps -ef|grep nginx

root 15208 1 0 14:14 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
nobody 16563 15208 0 15:34 ? 00:00:00 nginx: worker process 
root 17086 16288 0 15:50 pts/0 00:00:00 grep nginx

kill -quit 15208

快速停止nginx

kill -term 15208

強制停止nginx

pkill -9 15208

若在nginx.conf配置了pid檔案存放路徑則該檔案存放的就是nginx主程序號，如果沒指定則放在nginx的logs目錄下

kill -訊號型別  '/usr/nginx/logs/nginx.pid'

平滑重啟

如果更改了配置就要重啟nginx，要先關閉nginx再開啟？不是的，可以向nginx 傳送訊號，平滑重啟。

平滑重啟命令

kill -hup 15208

或者使用

nginx -s reload

注意，修改了配置檔案後最好先檢查一下修改過的配置檔案是否正確，以免重啟後nginx出現錯誤影響伺服器穩定執行。判斷nginx配置是否正確命令如下：

nginx -t -c /usr/nginx/conf/nginx.conf 或

nginx -t （推薦） 或

/usr/nginx/sbin/nginx -t
