Fatal error: $CFG->dataroot is not writable, moodle

Fatal error: $CFG->dataroot is not writable Today I ran into the same error. After a while i got the idea. On any linux box such as Red Hat, Cent OS, fedora and Co there is a pretty good likelihood that SELinux is enabled and enforced. First of all you should check the directory and file permissions. Being at least accessible and readable to the web server - most often apache. Dirs and files should be owned by apache:apache. The SELinux is quite consequent. I therefore ran into this issue after relabelling the system. In case that after permission setting the web server still does complain about „$CFG->dataroot not writable“ look at the SELinux labels of the dirs and files in $CFG->dataroot. They are displayed with the CLI ls -lZ /full_path_of_dataroot All labels should be apache apache unconfined_u:object_r:httpd_sys_rw_content_t:s0 4096 1. Dez 14:21 cache The httpd_sys_rw_content shows that the dir or file is writeable. In case this is not given execute sudo chcon -R -t httpd_sys_rw_content_t /full_path_of_dataroot This will change the file context recursively to the type httpd read/write. Reload the webpage.
