我在centos7(aws的ec2-instance)上安裝了nginx + mysql + nodejs。 一個簡單的節點應用程序工作正常。它可以通過捲曲和通過網絡瀏覽器訪問。但一個簡單的快速應用程序不能通過webbrowser工作(響應502)。它只能通過捲曲http://MY-PRIVATE-IP:8080。 在我本地安裝的服務器上,每個人都認爲沒問題。 注意:我沒有安裝express express。可能是米。錯誤?nginx上的Express.js應用程序
有什麼想法?我會很感激你的想法。感謝名單。
這裏是我的nginx的配置的詳細信息節點的應用程序:
nginx.conf
user nginx;
worker_processes 2;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
#worker_rlimit_nofile 30000;
events {
worker_connections 1024;
}
http {
index index.php index.htm index.html;
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
keepalive_timeout 65;
types_hash_max_size 2048;
gzip on;
#include /etc/nginx/conf.d/*.conf;
upstream node_upstream {
server MY-PRIVATE-IP:8080;
}
server_tokens off;
server {
listen 80;
listen [::]:80;
server_name _;
root /var/www/html;
# Load configuration files for the default server block.
#include /etc/nginx/default.d/*.conf;
location /myapp {
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_http_version 1.1;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_pass http://node_upstream;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
}
應用的NodeJS:hallo.js
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hallo Welt\n');
}).listen(8080, 'MY-PRIVATE-IP');
console.log('Server running at http://MY-PRIVATE-IP:8080/');
expressjs應用:hello.js
var express = require('express');
var app = express();
app.get('/', function (req, res) {
res.send('Hello World!');
});
app.listen(8080, function() {
console.log('Example app listening on port 8080!');
});
更改server_name 52.38.xx.xx後,不幸地訪問失敗,並顯示此日誌: 79.248.x.xx - - [30/Apr/2016:20:15:57 +0000]「GET/myapp HTTP/1.1 「404 19」 - 「」Mozilla/5.0(Windows NT 6.1; WOW64; rv:45.0)Gecko/20100101 Firefox/45.0「」 - 「 – Asman
服務器名稱應該是您的url,而不是服務器的IP地址(除非您使用當試圖訪問您的網站,這是不推薦的IP)。您是否嘗試過將proxy_pass指令指向端口8080,應用程序正在偵聽? –
