背景提要
由于要做APP审查，网站证明书过期，请同事更新下证明书， 更新完证明书，apache 不能重启了
重启所报错误
[root@xxx ~]# systemctl start httpd.service
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.
[root@xxx ~]# systemctl restart httpd
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.
用 systemctl status httpd 命令查看，结果如下：
[root@xxx conf.d]# systemctl status httpd

通过 搜索 【apache 再启动 kill[21919]: kill: cannot find process 】关键字，找到下面这篇文章：``
最终通过查看 apache error_log 和 ssl 的 error_log 找到原因：
tail -n 20 /var/log/httpd/error_log：

同事把证明书恢复成之前的之后，apache 就可以启动起来了
