1、查看当前运行的配置文件
[root@syjmw-app-13 ~]# netstat -anop | grep 0.0.0.0:80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 16463/nginx off (0.00/0/0)
tcp 0 0 0.0.0.0:8001 0.0.0.0:* LISTEN 7815/java off (0.00/0/0)
[root@syjmw-app-13 ~]# ll /proc/16463/exe
lrwxrwxrwx. 1 root root 0 4月 26 04:10 /proc/16463/exe -> /hnisi/local/nginx/nginx
[root@syjmw-app-13 ~]# /hnisi/local/nginx/nginx -t
nginx: the configuration file /hnisi/local/nginx/nginx.conf syntax is ok
nginx: configuration file /hnisi/local/nginx/nginx.conf test is successful
2、查看当前运行nginx的进程号
[root@syjmw-app-13 ~]# ps -ef | grep nginx
root 16463 1 0 Apr25 ? 00:00:00 nginx: master process ./nginx
root 20172 19460 0 19:12 pts/0 00:00:00 grep nginx
nobody 24161 16463 0 Apr25 ? 00:00:18 nginx: worker process
nobody 24162 16463 0 Apr25 ? 00:00:24 nginx: worker process
3、nginx启动、重启、停止命令
从容地重启：kill -HUP pid
启动nginx：./nginx
重启nginx：./nginx -s reload
停止nginx：./nginx -s stop
4、查出nginx的PID->通过PID查出端口号
[root@syjmw-app-13 ~]# ps -ef | grep nginx
root 16463 1 0 Apr25 ? 00:00:00 nginx: master process ./nginx
root 20827 19460 0 19:33 pts/0 00:00:00 grep nginx
nobody 24161 16463 0 Apr25 ? 00:00:18 nginx: worker process
nobody 24162 16463 0 Apr25 ? 00:00:24 nginx: worker process
[root@syjmw-app-13 ~]# netstat -antup | grep 16463
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 16463/nginx
