停止
查看进程号：
$ ps -ef|grep nginxroot 5747 1 0 May23 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx500 12037 7886 0 10:00 pts/1 00:00:00 grep nginxnobody 25581 5747 0 Sep27 ? 00:01:16 nginx: worker process nobody 25582 5747 0 Sep27 ? 00:01:25 nginx: worker process nobody 25583 5747 0 Sep27 ? 00:02:59 nginx: worker process nobody 25584 5747 0 Sep27 ? 00:02:05 nginx: worker process
杀死进程：
$ kill -9 5747
重启
1. 验证nginx配置文件是否正确
进入nginx安装目录sbin下，输入命令：
$ ./nginx -t …… nginx.conf syntax is ok …… nginx.conf test is successful
看到如上显示，说明配置文件正确！
2. 重启nginx服务
进入nginx安装目录sbin下，输入命令：
# ./nginx -s reload或者# kill -HUP 5747
