我正在尝试这样做，而不是输入“www.example.com:8080”，而只需输入“www.example.com”。我正在使用 NGINX，但似乎无法让它工作。我在网上找到了很多有用的文章，它们都说要做同样的事情，我试过了，但没有用。
我在 ubuntu apache2 服务器上运行
这是我所做的：
- 使用 Sudo 进入位于 /etc/nginx/site-enabled/default 的配置文件
- 将 listen 80 改为 listen 8080
- sudo 服务 nginx 重启
但这似乎并没有什么效果。

我对上面的默认配置文件进行了以下编辑并重新启动，但似乎仍然不起作用
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
root /usr/share/nginx/html;
index index.html index.htm;
# Make site accessible from http://localhost/
server_name localhost;
location / {
proxy_pass 127.0.0.1:8080;
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
# try_files $uri $uri/ =404;
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
}
....
}
---已解决的问题---
我的配置文件没有问题。当我查阅 /var/log/nginx/error.log 时，我看到了错误
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
因此我运行了以下命令：
sudo fuser -k 80/tcp
service nginx start
一切正常:)
答案1
你搞反了。
端口 80 是默认的 HTTP 端口，因此输入的www.example.com内容与输入www.example.com:80
将您的 listen 指令改回listen 80;，确保您以 root 身份启动 nginx，并且该端口没有被防火墙阻止，这样就没问题了。
如果您的后端应用程序已经在监听端口 8080，您需要告诉 nginx 将请求路由到该地址。
location / {
proxy_pass http://127.0.0.1:8080;
}
这样，当请求从端口 80 进入时，nginx 会将其发送到端口 8080 上的应用程序，然后 nginx 将响应返回给 nginx - 然后 nginx 将其返回给在任何地方都看不到端口 8080 的用户。
