1.查看是否安装检查状态模块；
[root@localhost ~]# nginx -Vnginx version: nginx/1.12.2built by gcc 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)configure arguments: --prefix=/usr/local/nginx --with-http_sub_module
2.如未安装，重新编译安装；
检查状态模块；--with-http_stub_status_module
[root@localhost ~]# cd /usr/local/src/nginx-1.12.2/ [root@localhost ~]# ./configure --prefix=/usr/local/nginx --with-http_stub_status_module[root@localhost ~]# make && make install
3.编辑nginx 的配置文件；
[root@localhost ~]# vim /usr/local/nginx/conf/nginx.confserver { listen 80; server_name localhost; #access_log logs/host.access.log main; location /nginx_status { stub_status on; access_log off; #allow 127.0.0.1; ##可对该页面的访问者进行过滤 #deny all; } }[root@localhost ~]# nginx -tnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful[root@localhost ~]# nginx -s reload
4.测试语法；
[root@localhost ~]# curl http://192.168.10.110:80/nginx_statusActive connections: 1server accepts handled requests 1 1 1Reading: 0 Writing: 1 Waiting: 0
5.输出内容详解；
第一行 Active connections: 1 ――活跃的连接数量，包括等待客户端数0
第二行 server accepts handled requests ―― 总共处理了1个连接 , 成功创建1次握手, 总共处理了1个请求
第三行 Reading ― 读取客户端的连接数，Writing ― 响应数据到客户端的数量，Waiting ― 开启 keep-alive 的情况下,这个值等于 active (reading+writing), 意思就是 Nginx 已经处理完正在等候下一次请求指令的驻留连接
