Apache2 地址已在使用中...无法绑定到地址 0.0.0.0:80（无法启动 apache）

尝试了其他答案中针对同一问题的一些方法。仍然无法解决。需要注意的一点是：我正在运行 gitlab-ctl。

有用信息：

如果你以超级用户身份运行“netstat”：

sudo netstat -tulpn | grep 80

这应该会显示正在使用端口 80 的进程，这可能会对您有所帮助。如果没有进一步的信息，听起来 Gitlab 可能已经在使用端口 80，在我的 Gitlab 安装中，它默认在端口 80 上使用 nginx。

您是否曾经重新安装过 Gitlab？查看 grep 输出中的“gitlab.conf.bac”文件，我猜您先使用 Apache 安装了 Gitlab，然后可能使用 nginx 重新安装了？

因此以 sudo 身份检查 netstat，我想这就是你的答案。
