CentOS 7.x with firewallcmd
Incoming traffic on port 80 may be blocked by default. If so, we must create a permanent firewall rule to accept incoming traffic to our DokuWiki website.
sudo firewall-cmd --permanent --zone=public --add-service=http sudo firewall-cmd --reload
Ensure apache service always starts on boot.
sudo systemctl enable httpd.service
mod_rewrite must be enabled so the .htaccess file which locks down the /data directory can be executed.
mod_rewrite is enabled by default on CentOS 7.x, if you need to re-enable it add the following line to a new .conf file and restart apache to load the mod_rewrite module
echo LoadModule rewrite_module modules/mod_rewrite.so > /etc/httpd/conf.d/addModule-mod_rewrite.conf sudo systemctl restart httpd.service
The PHP GD module must be installed for image resizing.
sudo yum install php-gd
CentOS comes with SELinux enabled by default which prevents the apache user from writing to the Document Root and sub directories.
Option 1 Switch SELinux to permissive mode, only for the httpd(Apache) service. This will leave SELinux enforcing for the rest of the system. This is the easier solution, but arguably also the less safe, as SELinux does not provide any protection for httpd.
sudo yum install policycoreutils-python sudo semanage permissive -a httpd_t
Option 2 Modify SELinux context (conf & data directories)
sudo semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/html/dokuwiki/conf(/.*)?" (Try adding -h option if it doesn't work) sudo semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/html/dokuwiki/data(/.*)?" sudo restorecon -Rv /var/www/html/dokuwiki/conf sudo restorecon -Rv /var/www/html/dokuwiki/data
For option 2: Using the Wiki Upgrade Plugin & the Extension Manager
To use the Wiki Upgrade Plugin & the Extension Manager with option 2 you also have to grant apache access to the network, otherwise you will get the error : Could not connect Permission denied
sudo setsebool -P httpd_can_network_connect on
getsebool -a | grep httpd_can_network_connect
If a HTTP 500 error code is returned, maybe the SELinux context of the files in the /var/www/dokuwiki directory is incorrect. The required context appears to be “httpd_sys_content_t”
