Apache 未启动 : (98)Address already in use

Question

昨天我的 WordPress 网站离线显示错误 ERR_CONNECTION_REFUSED .今天我发现我的 VPS 中的 Apache 已关闭。启动 Apache，我的控制面板返回:

Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

我试图发现端口上正在运行哪些服务，以杀死它们，但端口 80 和 443 没有被使用。

通过专门查询这些端口，它们返回:

80/tcp closed http
443/tcp closed https

即使门关闭，尝试启动 apache 服务时也会发生错误。我搜索了 Stack Overflow 的答案，尝试了所有关于这些问题的答案方法，但都没有解决问题。

我正在使用更新的 Webmin在 CentOS 7.7.1908

Answer 1

执行以下命令检查端口 443 是否被其他服务使用:

netstat -tunlp | grep 443

如果没有输出，请确保 Listen 443指令未在您的域的 Apache 虚拟主机目录中设置多次。
