所以后我apt-get安装它，我试图启动Nginx。然后我得到这样的消息：

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。

然后我试图修改Nginx.conf，我引用了一些文章，所以我改成它这样：

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";
        }

保存此并尝试再次启动Nginx后，我仍然得到与以前相同的错误。我不能真正找到一个相关的帖子这个，可以任何好的人shred一些光？

提前致谢 ：)

================================================== =====================

我应该把所有的内容在conf这里：

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，我没有改变任何东西，除了添加服务器部分。
