Nginx配置检测服务状态的实现方法

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 C (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.
