Nginx(2) 啟動，停止，訊號控制
一，啟動，停止，檢查配置檔案和重啟
啟動
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
停止
kill -QUIT pid 溫和停止
kill -TERM pid 快速停止
kill -INT pid 快速停止
強制停止
pkill -9 nginx
驗證配置檔案是否沒錯
/usr/local/nginx/sbin/nginx -t
或 /usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
重啟
./nginx -s reload 或者 kill -HUP pid
二，訊號控制
PUB重啟
QUIT溫和關閉
INT溫和關閉
TERM強制關閉
USR1切日誌
USR2平滑升級
WINCH關閉共總程序

[[email protected] nginx-1.10.1]# ps -ef|grep nginx
root 7110 1 0 11:12 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
nobody 7111 7110 0 11:12 ? 00:00:00 nginx: worker process
root 7116 28925 0 11:12 pts/0 00:00:00 grep nginx
可以看到 7110是主程序，7111是工作程序
