Have you made any configuration changes? Does just rebooting the system is causing the issue? The error log does not showing any error.Can you enable the 'debug' level logging and try to restart your httpd service? and share the logs.
您是否进行了任何配置更改？重新启动系统是否会导致问题？错误日志未显示任何错误。您是否可以启用“调试”级别日志记录并尝试重新启动httpd服务？并分享日志。
From the logs it seems you apache was started but immediately after few seconds it's shutdown.So,something is causing this shutdown.Have you configured any cron job for such service?
从日志开始，似乎你的apache已经启动，但几秒钟之后立即关闭。所以，有些东西导致了这种关闭。你是否为这样的服务配置了任何cron作业？

Turns out SSLSessionCache was causing the issue
原来SSLSessionCache导致了这个问题
I had to go into /etc/httpd/conf.d ssl.conf
我不得不进入/etc/httpd/conf.d ssl.conf
and comment out
并评论出来
#SSLSessionCache shmcb:/run/httpd/sslcache(512000)
#SSLSessionCache shmcb：/ run / httpd / sslcache（512000）
