apache - CentOS 7 apachectl httpd.service 启动失败

Question

我正在 build https://github.com/devopsgroup-io/catapult-release-management并且每隔一段时间尝试 apachectl start 就会出现以下错误:

httpd.service 的作业失败。有关详细信息，请参阅“systemctl status httpd.service”和“journalctl -xn”。

systemctl status httpd.service 输出:

有什么想法吗？

Answer 1

这是因为/etc/httpd/conf/httpd.conf 被追加了超过 20 行 IncludeOptional sites-enabled/*.conf

这是 apachectl configtest 中的错误，因为它报告正确的配置但不提供可追踪的错误。
