amazon-web-services - Dokku：Nginx 失败，地址已在使用中

问题描述

我正在尝试在 AWS 上托管的全新 Ubuntu 16.04 实例上安装 Dokku。连接是通过 ssh。由于 Nginx 错误，安装脚本反复失败。我不熟悉 Nginx，所以我无法解释问题所在。我最初尝试在 Ubuntu 14 上安装。我在那里遇到了同样的错误。Dokku 文档表明 Ubuntu 14 上的 apt 存储库可能存在问题。我按照步骤使用更新的 Nginx 更新了 apt 存储库，但这不起作用。所以我搬到了一个 Ubuntu 16.04 实例。但是，我仍然有这个问题。问题是什么，我该如何解决？谢谢。

Nginx 版本：

$ nginx -v
nginx version: nginx/1.10.3 (Ubuntu)

根据 Dokku 的命令：

wget https://raw.githubusercontent.com/dokku/dokku/v0.12.12/bootstrap.sh

（没有问题）

sudo DOKKU_TAG=v0.12.12 bash bootstrap.sh

（导致以下错误）

错误日志如下：

解决方案

弄清楚了。一些 apache 服务器正在监听端口 80。这个答案显示了如何改变它。

将 apache 配置为侦听 80 以外的端口
