我删除了整个日志文件目录。
sudo apachectl start
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

更新：
现在在error_log中我发现信息：
(13)Permission denied: AH00091: httpd: could not open error log file /etc/httpd/logs/ssl_error_log.
当我想启动 mongod 服务时我得到了相同的日志......

我在这里找到了答案： https://unix.stackexchange.com/questions/377903/can-not-restart-the-httpd-service/377932#377932
I saw your environment is development, not production.
So set the selinux permissive model can be help
Follow the steps:
# getenforce
# setenforce 0 // there will print `Permissive`
# systemctl start httpd.service
Check it :
systemctl status httpd.service
但无论如何，您的回答帮助我摆脱了困境。
答案1
你的错误是could not open error log file /etc/httpd/logs/ssl_error_log
你说你删除了整个日志文件夹；问题是虽然 Apache 很乐意创建日志文件在启动时，它不会创建文件夹。
/etc/httpd/logs是指向 的符号链接/var/log/httpd，因此问题是“您删除了什么？”。
执行ls -ld /var/log/httpd /etc/httpd/logs。
您可能只会看到其中一个，而出现错误提示另一个不存在。
创建/etc/httpd/logs执行ln -s /var/log/httpd /etc/httpd/logs
要创建/var/log/httpd执行mkdir -p /var/log/httpd && chmod go= /etc/httpd/logs。这将创建文件夹并为其设置最低权限。
我已将文件夹权限设置为最低，打开日志时 apache 将以 root 身份运行，因此这不是问题。稍后您可能需要或希望放宽权限。
答案2
以 root 身份运行来重新创建它：
touch /var/log/httpd/error_log
然后重新启动 apache。
