linux - 自从安装了 Docker/Discourse 之后，GitLab 就不再工作了

Question

我曾经在我的硬件服务器 (Ubuntu 14.04) 上有一个始终保持最新的 GitLab 实例。

但是，我最近决定安装 Discourse(或 Docker)，现在 GitLab 无法正常启动。

当我运行该服务时，sidekiq 进程启动但 Unicorn worker 未启动:

不，Docker 不会尝试绑定(bind) GitLab 使用的端口:

Nginx 正在运行，但只显示:

“502 - GitLab 没有响应。”

有人可以帮帮我吗？

提前致谢。

Answer 1

我刚发现问题。

我以某种方式忽略了 bash 调试输出中的消息:

master 启动失败，查看 stderr 日志获取详细信息

所以我打开了/home/git/gitlab/log/unicorn.stderr.log.1，我看到了以下内容:

/home/git/gitlab/vendor/bundle/ruby/2.1.0/gems/unicorn-4.6.3/lib/unicorn/socket_helper.rb:147:in `initialize': Address already in use - bind(2) for "127.0.0.1" port 8080 (Errno::EADDRINUSE)

然后我突然想到:Discourse 的 Nginx 使用与 GitLab 的 unicorn workers - 8080 相同的端口

我调整了那个端口，瞧，一切都恢复正常了。
