启动Nginx：nginx或nginx -c
[root@ansible sbin]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf #若不用-c指定配置文件，则以默认配置启动

快速停止或关闭Nginx：nginx -s stop
[root@ansible sbin]# /usr/local/nginx/sbin/nginx -s stop

正常停止或关闭Nginx：nginx -s quit
[root@ansible sbin]# /usr/local/nginx/sbin/nginx -s quit

配置文件修改重装载命令：nginx -s reload
[root@ansible sbin]# /usr/local/nginx/sbin/nginx -s reload

重新打开日志文件：nginx -s reopen
[root@ansible sbin]# /usr/local/nginx/sbin/nginx -s reopen

打开帮助信息：nginx -h
[root@ansible sbin]# /usr/local/nginx/sbin/nginx -h
nginx version: nginx/1.8.1
Usage: nginx [-?hvVtq] [-s signal] [-c filename] [-p prefix] [-g directives]

Options:
-?,-h : this help
-v : show version and exit
-V : show version and configure options then exit
-t : test configuration and exit
-q : suppress non-error messages during configuration testing
-s signal : send signal to a master process: stop, quit, reopen, reload
-p prefix : set prefix path (default: /usr/local/nginx/)
-c filename : set configuration file (default: conf/nginx.conf)
