nginx 26145 0.0 0.0 46348 1636 ? S 10:45 0:00 nginx: worker process
#启动nginx

###平滑启动的意思是在不停止nginx的情况下，重启nginx，重新加载配置文件，启动新的工作线程，完美停止旧的工作线程
#强制停止nginx
[root@aliyun ~]# pkill -9 nginx
[root@aliyun ~]# ps -aux | grep nginx | grep -v grep
#检查对nginx.conf文件的修改是否正确
[root@aliyun ~]# /usr/local/nginx/sbin/nginx -t #如果nginx配置到环境变量中可写相对路径
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
#停止nginx
[root@aliyun nginx]# /usr/local/nginx/sbin/nginx -s stop
[root@aliyun nginx]# ps -aux | grep nginx | grep -v grep
#查看nginx版本信息
[root@aliyun nginx]# /usr/local/nginx/sbin/nginx -v
nginx version: nginx/1.1.18
#查看nginx的完整配置
[root@aliyun nginx]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.1.18
