各位大大好
我在伺服器(os:centos7)啟動selinux後，開啟httpd出現了問題，(selinux關閉，可以正常啟動httpd)
錯誤訊息如下

[root@localhost ~]# systemctl status httpd -l
● httpd.service - The Apache HTTP Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since 四 2022-03-10 14:29:02 CST; 43s ago
     Docs: man:httpd.service(8)

httpd error_log 如下

[root@localhost ~]# tail /var/log/httpd/error_log

看起來問題好像是

Permission denied: AH00023: Couldn't create the ssl-cache mutex
AH00016: Configuration Failed

不曉得是哪個目錄或檔案的安全性本文或rwd權限沒有設定好?或是要修改selinux policy? 才能成功啟動httpd
再麻煩各位大大協助，謝謝!
