今天无法打开站点, 猜测 httpd.service 服务肯定又停止了, 可能是受到外部攻击 (也可能是来自自己的攻击)
首先查看 httpd.service 状态 , 结果如下, 果然在一周以前的时候就停止了, 换算成北京时间应该是 9 月 20 日下午, 那时可能是我在测试. 但是我查阅当日工作日志并没有发现相关的信息, 不太确定是不是遭遇了外部攻击, 或者是服务器资源不足导致 Apache 自己运行出现了问题. 具体问题暂时不想再纠结了, 自己水平目前真的太菜, 还有很多东西要学习, 暂时无精力去调查了, 以后测试时做好记录, 便于分析攻击来源.

我的服务器肯定也没有重启过, 我还是顺手添加开机启动 (因为之前就是开机启动的)
- [root@tac HTML]# systemctl enable httpd.service
- Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
重启 httpd.service 服务
[root@tac HTML]# systemctl restart httpd.service
再查看 httpd.service 的状态
