[root@TA30-53 nginx]# ./sbin/nginx -s quit
-s都是采用向 Nginx 发送信号的方式
Nginx 重载配置
[root@TA30-53 nginx]# ./sbin/nginx -s reload
上述是采用向 Nginx 发送信号的方式，或者使用：service nginx reload
指定配置文件
[root@TA30-53 nginx]# ./sbin/nginx -c /usr/local/nginx/conf/nginx.conf
-c表示configuration，指定配置文件
查看 Nginx 版本
[root@TA30-53 nginx]# ./sbin/nginx -vnginx version: nginx/1.8.0
[root@TA30-53 nginx]# ./sbin/nginx -Vnginx version: nginx/1.8.0built by gcc 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC) configure arguments:
检查配置文件是否正确
[root@TA30-53 nginx]# ./sbin/nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

在Linux下通过master发送信号的相关命令
停止操作
[root@TA30-53 nginx]# ps -ef|grep nginxroot 15208 1 0 14:14 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginxnobody 16563 15208 0 15:34 ? 00:00:00 nginx: worker process root 17086 16288 0 15:50 pts/0 00:00:00 grep nginx
从容停止Nginx
kill -QUIT 15208
快速停止Nginx
kill -TERM 15208
强制停止Nginx
pkill -9 15208
若在nginx.conf配置了pid文件存放路径则该文件存放的就是Nginx主进程号，如果没指定则放在nginx的logs目录下
有了pid文 件，就不用先查询Nginx的主进程号，而直接向Nginx发送信号了，命令如下（推荐）：
kill -信号类型 '/usr/nginx/logs/nginx.pid'
平滑重启
如果更改了配置就要重启Nginx，要先关闭Nginx再打开？不是的，可以向Nginx 发送信号，平滑重启。
平滑重启命令 kill -HUP 15208
或者使用 nginx -s reload
注意，修改了配置文件后最好先检查一下修改过的配置文件是否正确，以免重启后Nginx出现错误影响服务器稳定运行。判断Nginx配置是否正确命令如下：
nginx -t -c /usr/nginx/conf/nginx.conf
或
nginx -t （推荐）
或
/usr/nginx/sbin/nginx -t
