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
[root@tac html]# systemctl status httpd.service
