我已经在服务器上设置了Node.js和Nginx。现在我想用它,但是在我开始之前有两个问题:

How should they work together? How should I handle the requests? There are 2 concepts for a Node.js server, which one is better: a. Create a separate HTTP server for each website that needs it. Then load all JavaScript code at the start of the program, so the code is interpreted once. b. Create one single Node.js server which handles all Node.js requests. This reads the requested files and evals their contents. So the files are interpreted on each request, but the server logic is much simpler.

我不清楚如何正确使用Node.js。

带有Nginx配置的Node.js。

$ sudo nano /etc/nginx/sites-available/subdomain.your-domain.example

添加以下配置,这样当我们从subdomain.your_domain.example来的时候,Nginx作为代理将流量重定向到端口3000

upstream subdomain.your-domain.example {
  server 127.0.0.1:3000;
}
server {
  listen 80;
  listen [::]:80;
  server_name subdomain.your-domain.example;
  access_log /var/log/nginx/subdomain.your-domain.access.log;
  error_log /var/log/nginx/subdomain.your-domain.error.log debug;
  location / {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarder-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-NginX-Proxy true;
    proxy_pass http://subdomain.your-domain.example;
    proxy_redirect off;
  }
}

你也可以使用node.js生成静态文件到nginx提供的目录中。当然,站点的一些动态部分可以由node提供,而另一些则由nginx提供(静态)。

使用nginx提供的一些服务可以提高你的性能。

我通过Nginx代理独立的Node Express应用程序。

因此,新的应用程序可以很容易地安装,我也可以在同一服务器上的不同位置运行其他东西。

以下是关于我的Nginx配置示例设置的更多详细信息:

Deploy multiple Node applications on one web server in subfolders with Nginx Things get tricky with Node when you need to move your application from from localhost to the internet. There is no common approach for Node deployment. Google can find tons of articles on this topic, but I was struggling to find the proper solution for the setup I need. Basically, I have a web server and I want Node applications to be mounted to subfolders (i.e. http://myhost/demo/pet-project/) without introducing any configuration dependency to the application code. At the same time I want other stuff like blog to run on the same web server. Sounds simple huh? Apparently not. In many examples on the web Node applications either run on port 80 or proxied by Nginx to the root. Even though both approaches are valid for certain use cases, they do not meet my simple yet a little bit exotic criteria. That is why I created my own Nginx configuration and here is an extract: upstream pet_project { server localhost:3000; } server { listen 80; listen [::]:80; server_name frontend; location /demo/pet-project { alias /opt/demo/pet-project/public/; try_files $uri $uri/ @pet-project; } location @pet-project { rewrite /demo/pet-project(.*) $1 break; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $proxy_host; proxy_set_header X-NginX-Proxy true; proxy_pass http://pet_project; proxy_redirect http://pet_project/ /demo/pet-project/; } } From this example you can notice that I mount my Pet Project Node application running on port 3000 to http://myhost/demo/pet-project. First Nginx checks if whether the requested resource is a static file available at /opt/demo/pet-project/public/ and if so it serves it as is that is highly efficient, so we do not need to have a redundant layer like Connect static middleware. Then all other requests are overwritten and proxied to Pet Project Node application, so the Node application does not need to know where it is actually mounted and thus can be moved anywhere purely by configuration. proxy_redirect is a must to handle Location header properly. This is extremely important if you use res.redirect() in your Node application. You can easily replicate this setup for multiple Node applications running on different ports and add more location handlers for other purposes.

你也可以用Nginx设置多个域,转发到多个node.js进程。

例如实现这些:

domain1。example ->到本地运行的Node.js进程http://127.0.0.1:4000 domain2。example ->到本地运行的Node.js进程http://127.0.0.1:5000

这些端口(4000和5000)应该用来监听应用程序代码中的应用程序请求。

/etc/nginx/sites-enabled / domain1

server {
    listen 80;
    listen [::]:80;
    server_name domain1.example;
    access_log /var/log/nginx/domain1.access.log;
    location / {
        proxy_pass    http://127.0.0.1:4000/;
    }
}

在/etc/nginx/sites-enabled / domain2

server {
    listen 80;
    listen [::]:80;
    server_name domain2.example;
    access_log /var/log/nginx/domain2.access.log;
    location / {
        proxy_pass    http://127.0.0.1:5000/;
    }
}

如果你想管理并运行每个微服务,你可以使用pm2运行nodejs。节点将运行在一个端口上,只需在Nginx中配置该端口(/etc/ Nginx /sites-enabled/domain.example)

server{
    listen 80;
    server_name domain.example www.domain.example;

  location / {
     return 403;
  }
    location /url {
        proxy_pass http://localhost:51967/info;
    }
}

使用ping检查本地主机是否运行。

And

Create one single Node.js server which handles all Node.js requests. This reads the requested files and evals their contents. So the files are interpreted on each request, but the server logic is much simpler.

这是最好的,正如你说的,也更容易

我们可以通过Nginx作为反向代理来轻松地设置一个Nodejs应用程序。 以下配置假设NodeJS应用程序运行在127.0.0.1:8080上,

  server{
     server_name domain.example sub.domain.example; # multiple domains

     location /{
      proxy_pass http://127.0.0.1:8080;
      proxy_set_header Host $host;
      proxy_pass_request_headers on;
     }

     location /static/{
       alias /absolute/path/to/static/files; # nginx will handle js/css
     }
   }

在上面的设置中,你的Nodejs应用程序将

get HTTP_HOST头,在那里你可以应用域特定的逻辑来服务响应。 你的应用程序必须由一个进程管理器管理,比如pm2或supervisor来处理情况/重用套接字或资源等。 设置一个错误报告服务来获取生产错误,如哨兵或滚动条

注意:你可以设置处理域特定请求路由的逻辑,为expressjs应用程序创建一个中间件
