ubuntu - 如何通过不同端口(80 以外)启动 nginx

Question

嗨，我是 nginx 的新手，我试图在我的服务器(运行 Ubuntu 4)上设置它，它已经运行了 apache。

所以在我 apt-get install 它之后，我尝试启动 nginx。然后我收到这样的消息:

Starting nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
configuration file /etc/nginx/nginx.conf test is successful
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)

这是有道理的，因为 Apache 使用端口 80。

然后我尝试修改nginx.conf，我引用了一些文章，所以我改成这样:

   server {

        listen       8080;

        location / {
         proxy_pass  http://xx.xx.xx.xx:9500;
         proxy_set_header   Host             $host:8080;
         proxy_set_header   X-Real-IP        $remote_addr;
         proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
         proxy_set_header Via    "nginx";
        }
 

保存后再次尝试启动nginx，还是报同样的错误。我真的找不到与此相关的帖子，任何好人都可以提供一些帮助吗？

我应该在这里发布 conf 中的所有内容:

user www-data;
worker_processes  1;

error_log  /var/log/nginx/error.log;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
    # multi_accept on;
}

http {
    include       /etc/nginx/mime.types;

    access_log  /var/log/nginx/access.log;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;
    tcp_nodelay        on;

    gzip  on;
    gzip_disable "MSIE [1-6]\.(?!.*SV1)";

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;

   server {

        listen       81;

        location / {
         proxy_pass  http://94.143.9.34:9500;
         proxy_set_header   Host             $host:81;
         proxy_set_header   X-Real-IP        $remote_addr;
         proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
         proxy_set_header Via    "nginx";
        }


    }
}

 mail {
      See sample authentication script at:
      http://wiki.nginx.org/NginxImapAuthenticateWithApachePhpScript
 
      auth_http localhost/auth.php;
      pop3_capabilities "TOP" "USER";
      imap_capabilities "IMAP4rev1" "UIDPLUS";
 
     server {
         listen     localhost:110;
         protocol   pop3;
         proxy      on;
     }
 
     server {
         listen     localhost:143;
         protocol   imap;
         proxy      on;
     }
 }

基本上，除了添加服务器部分外，我没有做任何更改。

你必须去 /etc/nginx/sites-enabled/ 如果这是默认配置，那么应该有一个文件名:default .

通过定义所需的端口来编辑该文件；在下面的代码片段中，我们在端口 81 上提供 Nginx 实例。

server {
    listen 81;
}

要启动服务器，运行下面的命令行；

sudo service nginx start

您现在可以在端口 81 上访问您的应用程序(对于本地主机，http://localhost:81)。
