我正在使用nginx和haproxy，我希望haproxy绑定到端口80，所以我将nginx更改为端口81。但是当我将端口nginx更改为81然后启动nginx时仍然绑定在端口80并出现错误。对我来说有什么解决方案。
这是我的 nginx 配置默认在 /etc/nginx/sites-enabled

# In most cases, administrators will remove this file from sites-enabled/ and

# This file will automatically load configuration files provided by other
# applications, such as Drupal or Wordpress. These applications will be made
# available underneath a path with that package name, such as /drupal8.

# Default server configuration

# SSL configuration

我想同时使用 nginx 和 haproxy 有什么解决方案
您可能想在此处检查 nginx.conf 和 conf/*.conf 的内容。就我而言，它是conf/目录中的默认文件，正在侦听端口80。希望答案有帮助。
