Linux:在Nginx上设置node.js [英] Linux: Setting up node.js on nginx

问题描述

我刚刚给自己买了一个新的raspberry pi 3，并安装了带有node的nginx. Nginx Web服务器已启动并正在运行.但是不知何故，我无法获得网站工作的JavaScript.我需要为我的Web服务器的每个位置启用javascript吗，还是可以按照我只为服务器上的每个站点工作的方式来设置节点?

I just got myself a new raspberry pi 3 and installed nginx with node onto it. The nginx webserver is up and running. But somehow I don't get the javascripts of my website work. Do I need to enable the javascript for each location of my webserver or is there the possibility to set node up in a way I just works for every site on my server?

在这里您可以看到我网站的目录层次结构:

Here you can see the directory hierarchy of my websites:

#########################################
###            Directories            ###
#########################################
# /www/var/                             #
# | - > index.html (the hub/mainpage)   #

# | | - > index.html (website 1)        #

# | ...                                 #

当您访问我的网站( http://strtpg.xyz )时，主页位于/www/var之外/显示蜂鸣声.这是一个集线器，可以访问服务器上托管的所有其他站点.您可以通过将其文件夹名称附加到链接来访问其他站点: ' http://strtpg.xyz/proj1 '或'

When you go to my website (http://strtpg.xyz) the mainpage out of /www/var/ is beeing shown. It's kind of a hub where I got access to all other sites hosted on the server. And you can access the different sites by appending it's folder name to the link: e.g. 'http://strtpg.xyz/proj1' or 'http://strtpg.xyz/proj5'. Some of the sites got javascript and some don't.

这是我来自/etc/nginx/sites-available/的配置文件:

And this is my config file from /etc/nginx/sites-available/:

# Server configuration
#upstream pnkpnd {
#   server localhost:3420;
#   keepalive 8;
#}

server {
    listen 0.0.0.0:80;
    listen [::]:80;
    server_name localhost;
    index index.html index.htm;

    location / {
        root /var/www;
        try_files $uri $uri/ =404;
        # Default root of site won't exist.
        #return 410;
    }

    location /strtpg {
        root /var/www;
        try_files $uri $uri/ =404;
    }

    location /dshbrd {
        root /var/www;
        try_files $uri $uri/ =404;
    }

    location /pnkpnd {
        root /var/www;
        try_files $uri $uri/ =404;
#       proxy_http_version 1.1;
#       proxy_set_header Upgrade $http_upgrade;
#       proxy_set_header Connection 'upgrade';
#       proxy_set_header X-Real-IP $remote_addr;
#       proxy_set_header X-Forward-For $proxy_add_x_Forwarded_for;
#       proxy_set_header Host $http_host;
#       proxy_set_header X-NginX-Proxy true;
#       proxy_pass http://strtpg.xyz/;
#       proxy_redirect off;
    }

    location ~ /\.ht {
        deny all;
    }
}

我尝试使节点与我的网站一起工作的所有内容都被注释掉了，所以我至少可以看到网站本身.

All the stuff I tried out to get node working with my websites is commented out, so I can at least see the website itself.

推荐答案

Node通常用作侦听端口，提供静态文件并具有将在服务器中运行javascript的API端点的Web服务器.为了实现这一点，开发人员使用ExpressJS之类的应用程序框架.

Node is usually used as a Web server that listens to a port, serves static files and has API endpoints that will run javascript in the server. To achieve that developers use application frameworks like ExpressJS.

将nginx指向类似/var/www的目录是错误的.

Pointing nginx to a directory like /var/www is wrong.

通常，您必须像这样运行您的NodeJS应用

Usually you will have to run your NodeJS app like this

$ node app.js

之后，您的服务器将侦听端口.可以说在这种情况下是3000

After that you server will listen to a port. Lets say that in this case is 3000

，因此使用curl http://localhost:3000/将获得您的根站点.您可以从app.js内部来设置应用程序将要服务的所有静态和动态内容.例如:如果要发送index.html，则必须执行sendfile.

so using curl http://localhost:3000/ will get your root site. Its your job from inside app.js to setup all your static and dynamic content that your application will serve. Example: if you want to send index.html you have to do a sendfile.

在nginx方面，您唯一要做的就是创建反向代理.

In the nginx side the only thing you will have to do is to create a reverse proxy.

现在，nginx将把对example.com的所有请求代理到http://localhost:3000

Now nginx will proxy all requests that are made to example.com to your node application server at http://localhost:3000

server {
    listen 80;

    server_name example.com;

    location / {
        proxy_pass http://localhost:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }

}
