ubuntu – 如何通过不同的端口启动nginx(80以外的端口)

嗨我是nginx上的新手,我试图在我的服务器上运行它(运行Ubuntu 4),它已经运行了apache.

所以在我apt-get安装之后,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正在使用端口80.

然后我尝试修改nginx.conf,我引用了一些文章,所以我改变了它：

   server {

        listen       8080;

        location / {
         proxy_pass  http://94.143.9.34:9500;
         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";
        }

保存后再尝试再次启动nginx,我仍然得到与以前相同的错误.我真的找不到关于这个的相关帖子,任何好人都可以粉碎一些光吗？

我应该在conf中发布所有内容：

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,我什么也没做.
