How to implement Nginx configuration detection service status

1. Check whether the check status module is installed;

[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. If not installed, recompile and install;

Ø Check status module; --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. Edit the nginx configuration file;

[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; ##You can filter visitors to this page#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. Test grammar;

[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. Detailed explanation of output content;

The first line Active connections: 1 - the number of active connections, including waiting clients 0

The second line server accepts handled requests - a total of 1 connection was handled, 1 handshake was successfully created, and a total of 1 request was handled

The third line shows Reading — the number of connections reading from the client, Writing — the number of response data sent to the client, and Waiting — when keep-alive is enabled, this value is equal to active – (reading+writing), which means that Nginx has processed the resident connections that are waiting for the next request instruction.

The above is the full content of this article. I hope it will be helpful for everyone’s study. I also hope that everyone will support 123WORDPRESS.COM.
