Nginx作为前端服务器工作,在这种情况下,它将请求代理到node.js服务器。因此,您需要为节点设置一个Nginx配置文件。
这是我在Ubuntu盒子里所做的:
创建文件yourdomain。例如/etc/nginx/sites-available/:
vim /etc/nginx/sites-available/yourdomain.example
你应该有如下内容:
# the IP(s) on which your node server is running. I chose port 3000.
upstream app_yourdomain {
server 127.0.0.1:3000;
keepalive 8;
}
# the nginx server instance
server {
listen 80;
listen [::]:80;
server_name yourdomain.example www.yourdomain.example;
access_log /var/log/nginx/yourdomain.example.log;
# pass the request to the node.js server with the correct headers
# and much more can be added, see nginx config options
location / {
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://app_yourdomain/;
proxy_redirect off;
}
}
如果你想让Nginx(>= 1.3.13)也能处理websocket请求,在location / section中添加以下行:
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
一旦你有了这个设置,你必须启用上面配置文件中定义的站点:
cd /etc/nginx/sites-enabled/
ln -s /etc/nginx/sites-available/yourdomain.example yourdomain.example
在/var/www/yourdomain/app.js上创建你的节点服务器应用程序,并在localhost:3000上运行它
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(3000, "127.0.0.1");
console.log('Server running at http://127.0.0.1:3000/');
测试语法错误:
nginx -t
重启Nginx:
sudo /etc/init.d/nginx restart
最后启动节点服务器:
cd /var/www/yourdomain/ && node app.js
现在你应该在你的域名中看到“Hello World”
关于启动节点服务器的最后一点注意事项:您应该为节点守护进程使用某种监视系统。有一个很棒的教程关于节点与upstart和monit。
