The vts module in nginx is a very useful monitoring module, which allows us to clearly observe the current status of the server

1. Prepare the installation package and decompress it

First, we prepare the installation packages of nginx and vts

 and then unzip it

tar -zxvf nginx-1.22.0.tar.gz

unzip nginx-module-vts-master.zip

mv nginx-module-vts-master /usr/local

 2. Install dependent compilation software

yum -y install gcc gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel make

Here I have installed all

3. Compile and install nginx and modules

useradd -M -s /sbin/nologin nginx

#Creating users is to make nginx more flexible and give more permissions

./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --add-module=/opt/nginx-module-vts-master/   

 make && make install

 This completes the installation

4. Optimizing management

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/

 nginx -V #View nginx installation information

The vts module is also loaded here

nginx -t #Test it

Five, modify the configuration file

vim /usr/local/nginx/conf/nginx.conf #The configuration file is as follows

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;
