[wordpress] [selinux] mkdir(): Permission denied

Can't change configuration: Can't create folder /path/to/www/wp-content/cache/tmp: mkdir(): No such file or directory

  SELinux를 쓰고 있는데 위와 같은 오류 로그가 뜬다면, 보안 컨텍스트(security context)로 쓰기 권한을 주지 않았기 때문일 수 있다.

# chcon -R -t httpd_user_content_rw_t /path/to/www/wp-content/
# chcon -t httpd_user_content_rw_t /path/to/www/wp-content

# ls -lZ  /path/to/www/wp-content
...
drwxr-xr-x. apache  apache  system_u:object_r:httpd_user_rw_content_t:s0 cache
-rw-r--r--. website website unconfined_u:object_r:httpd_user_content_t:s0 index.php
drwxr-xr-x. website website unconfined_u:object_r:httpd_user_content_t:s0 languages

  httpd_user_content_t / httpd_user_content_rw_t 대신에 httpd_sys_content_t / httpd_sys_content_rw_t를 쓸 수도 있다.
