Can not write to cache files, please check directory (discuzx)

[mfung]

Can not write to cache files, please check directory ./data/ and ./data/sysdata/ .
相信在discuzx 好多人遇到這問題, 即使把data, 和 /data/sysdata/ 設成777也無法解決, 網上暫時無人提出解決方法

原因是CentOS7的SeLinux, 會block了 php的 fopen指令, 令你完全cache唔到

只要把SELinux關閉就可以, 只需一句command:

sudo setenforce 0

這便立即關了SELinux, 但是開機後又會再開, 因此你可以修改開機文件:

/etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#       enforcing - SELinux security policy is enforced.
#       permissive - SELinux prints warnings instead of enforcing.
#       disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#       targeted - Targeted processes are protected,
#       mls - Multi Level Security protection.
SELINUXTYPE=targeted

SELINUX=disabled

重新開機, 再check status

sestatus

SELinux status: disabled
