基本命令

1. 入门

1. 查看nginx进程: ps -ef|grep nginx

   404@40401:~$ ps -ef|grep nginx
   root      7996     1  0 Apr14 ?        00:00:00 nginx: master process nginx
   404     14126  6118  0 11:56 pts/79   00:00:00 more nginx.conf
   404     18278  7635  0 13:16 pts/88   00:00:00 grep --color=auto nginx
   nobody   31455  7996  0 Jun01 ?        00:03:26 nginx: worker process
   nobody   31456  7996  0 Jun01 ?        00:03:35 nginx: worker process
   nobody   31457  7996  0 Jun01 ?        00:03:25 nginx: worker process
   nobody   31458  7996  0 Jun01 ?        00:03:40 nginx: worker process
   

   这里进程的话主要由nobody执行,为什么是4个事因为在ngin.conf中设置了四核

   ## worker_processes的数值设置为cpu的核数
   worker_processes  4;
   ## 绑定每个nginx进程所使用的CPU，使nginx可以利用cpu的多核
   worker_cpu_affinity 0001 0010 0100 1000;
   

2. 检查配置文件的正确性: sudo nginx -t

   404@40401:~/env/nginx/default/conf$ sudo nginx -t
   [sudo] password for work:
   nginx: the configuration file 404/nginx.conf syntax is ok
   nginx: configuration file 404/nginx.conf test is successful
   

3. 检查nginx完整配置信息: sudo nginx -V

    nginx -V
   

4. 启动nginx:

   1. nginx
   2. nginx -s reload: 平滑启动nginx,表示不停止nginx的情况下重启nginx

5. 停止nginx:

   1. 完美停止nginx: kill -QUITcat /var/run/nginx.pid``
   2. 快速停止nginx: kill -INTcat /var/run/nginx.pid``
   3. 完美停止工作进程,只要用作平滑升级: kill -WINCHcat /var/run/nginx.pid``
   4. 强制停止nginx: pkill -9 nginx
   5. 停止ngix: nginx -s stop
