nginx常用命令

进入nginx目录

[root@TA30-53 nginx]# pwd /usr/local/nginx

启动 Nginx

[root@TA30-53 nginx]# ./sbin/nginx

停止 Nginx

[root@TA30-53 nginx]# ./sbin/nginx -s stop [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 -v nginx version: nginx/1.8.0 [root@TA30-53 nginx]# ./sbin/nginx -V nginx version: nginx/1.8.0 built 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 ok nginx: 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 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
