如何通过不同的端口启动nginx（80以外）

嗨，我是nginx的新手，我试图设置它在我的服务器（运行Ubuntu 4），已经有Apache运行。

所以，我apt-get install后，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 ，我参考了一些文章，所以我改变了它：

• Nginx负载均衡基于URL而不是IP地址？
• 在哪里把项目文件与nginx
• 命令/方法查找SSH服务器守护进程＆Nginx的运行时间
• 哪个php5-fpm设置为高并发连接数+ nginx
• nginx正在削减dynamic页面的结束并caching它们

  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"; } 

保存这个之后，再次尝试启动nginx，我仍然得到和以前一样的错误。 我真的不能find相关的post，有没有好的人可以点亮一下？

我应该在这里发布所有的内容：

 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，我什么也没有改变。

 listen [::]:80
