Check the current version of apache by running httpd –v
Then execute the following commands:
cd /usr/local/directadmin/customapache
./build clean
./build update
./build apache_mod_ssl
This should update both the configure options and the version of apache to the most recent version. Once the update is completed, restart apache:
RedHat:/sbin/service httpd restart
FreeBSD:/usr/local/etc/rc.d/httpd restart
