Use nginx to deploy multiple Web Servers on one server

This article mainly introduces the use of nginx to deploy multiple Web Servers on one server. It has certain reference value. Now I share it with you. Friends in need can refer to it.

Have you been tinkering recently? It took me a little time. I first thought of doing this because the way node directly starts the server is a bit violent, because if the 80 port is occupied, it is really occupied. It is difficult to use one 80 port to hang multiple WebServers. You can only mount it on multiple ports, and you have to add another port later to access it, which is too ugly, so I fumbled around and configured a multi-service structure using Nginx. In this way, different applications can be accessed through different subdomain names!

Rough structure

##Essentially, nginx is responsible for forwarding incoming requests, so the basis for forwarding is to determine different subdomain names

STEP 1 Install Nginx

The first step is of course to install nginx. Each platform is different and cannot be shared. My own ubuntu environment

apt-get isntall nginx

STEP 2 Set DNS AND PORT

Go to your domain name manager to allocate the subdomain name you want. Of course, they are all A records and are all resolved to your VPS public IP.

Another preparation is to modify the ports of all your NodeWebServers. You can set them according to your preferences, but do not occupy ports 80 and 443

STEP 3 nginx config Node.js

Switch to your

nginx configuration directory

My directory location

/etc/ nginx/

It should be noted here that nginx has an Include mechanism. It will automatically load all _.conf_ in the conf.d directory (under the default configuration), so we do not need to modify the nginx.conf file. We next need to create a series of configuration files in the conf.d directory. Please use your corresponding project name for the file name, such as

project1.conf

If not, please add it manually

        include /etc/nginx/conf.d/*.conf;
        # include /etc/nginx/sites-enabled/*; // 最好给他注释了 默认页面没啥用

Start writing project configuration

cd conf.d

touch project1.conf

vim project1.conf

Let’s write the detailed forwarding Rule

// 这是一个NODE Web Server
// 我已经将这个服务的端口改成了8000端口
// 当nginx捕获到访问域名为api.yinode.tech的时候
// 就会转发到本地的8000端口
server{
    server_name api.yinode.tech;
    listen 80;
    location / {
        # proxy_http_version 1.1;
        proxy_set_header Connection "";
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;
        proxy_pass http://127.0.0.1:8000$request_uri;
        proxy_redirect off;
    }
}

If you need to forward HTTPS, please copy the above content and paste it below, change the listening port to 443, and the forwarding port is the https port you are listening on!

STEP 4 nginx config PHP

The forwarding settings of php will be slightly different, (by default you have already installed PHP)

server {
  listen 80;
  root /var/www/longqiyoutian/wordpress; // 你的根目录
  index index.php;
  server_name dragon.yinode.tech;
  error_page 404 /404.html;
  location ~ \.php$ {
    try_files $uri = 404;
    fastcgi_pass unix:/var/run/php/php7.0-fpm.sock; // 你的fpm地址
    fastcgi_index index.php;
    include fastcgi_params;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name; // 必须填写，注意顺序
  }
}

Explain one by one, first our Root The directory will become important. Nginx will forward this directory to FPM to run the PHP code, so don’t write it wrong. Secondly, the subsequent forwarding must be added

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;This can Guide fpm to perform correct address splicing

TIPS: Reminder

The default startup user of nginx and FPM is www-data, so be sure to change the owner of your website root directory to www-data , and do not place this directory under /root/, as permission problems will occur. It is best to copy it to the /var/www directory and set the owner!

STEP 5 Repeat

Repeat 3 and 4 steps to create all the project configurations you need

STEP 6 Restart nginx

service nginx restart

If an error occurs, check the information carefully and search online. It is usually because the configuration file format is incorrect.

STEP 7 Run

Open your website, it should run normally! In fact, if you add a new server in the future, you only need to add a corresponding conf file, which can be easily expanded horizontally, and the entire website will be more beautiful to visit!
