1. 查看是否安装检查状态模块；
[root@localhost ~]# nginx -V nginx version: nginx/1.12.2 built 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；
Ø 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.conf
server {
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 -t
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
[root@localhost ~]# nginx -s reload
4. 测试语法；
[root@localhost ~]# curl http://192.168.10.110:80/nginx_status Active connections: 1 server accepts handled requests 1 1 1 Reading: 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. |
