Nginx的基本信息检查：

检查配置文件的正确性：

[root@ServerCenter www]# /opt/nginx/sbin/nginx -t
nginx: the configuration file /opt/nginx/conf/nginx.conf syntax is ok
nginx: [warn] 65536 worker_connections exceed open file resource limit: 1024
nginx: configuration file /opt/nginx/conf/nginx.conf test is successful
[root@ServerCenter www]#
[root@ServerCenter www]# /opt/nginx/sbin/nginx -t -c /opt/nginx/conf/nginx.conf

nginx: [warn] 65536 worker_connections exceed open file resource limit: 1024
nginx: configuration file /opt/nginx/conf/nginx.conf test is successful
[root@ServerCenter www]#

显示版本信息以及相关的编译信息：

[root@ServerCenter www]# /opt/nginx/sbin/nginx -v
nginx version: nginx/1.2.4
[root@ServerCenter www]# /opt/nginx/sbin/nginx -V
nginx version: nginx/1.2.4

[root@ServerCenter www]#

启动：

[root@ServerCenter www]# ps -ef | grep nginx
root     13422 12848  0 17:31 pts/2    00:00:00 grep nginx
[root@ServerCenter www]#
[root@ServerCenter www]# /opt/nginx/sbin/nginx
nginx: [warn] 65536 worker_connections exceed open file resource limit: 1024
[root@ServerCenter www]#
[root@ServerCenter www]# ps -ef | grep nginx
root     13427     1  0 17:31 ?        00:00:00 nginx: master process /opt/nginx/sbin/nginx
nobody   13428 13427  0 17:31 ?        00:00:00 nginx: worker process
nobody   13429 13427  1 17:31 ?        00:00:00 nginx: worker process

nobody   13431 13427  1 17:31 ?        00:00:00 nginx: worker process
root     13434 12848  0 17:31 pts/2    00:00:00 grep nginx
[root@ServerCenter www]#

获取Nginx的PID信息：

[root@ServerCenter ~]# ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'
4007
[root@ServerCenter ~]#
[root@ServerCenter ~]# cat /opt/nginx/logs/nginx.pid
4007
[root@ServerCenter ~]#

发信号关闭Nginx：

[root@ServerCenter ~]# kill -QUIT 4007
[root@ServerCenter ~]#
[root@ServerCenter ~]# ps -ef | grep --color nginx
root      4042  3958  0 22:08 pts/2    00:00:00 grep --color nginx
[root@ServerCenter ~]#
