Adding Linode Server

1. Log in to your Linode Manager and click "Add a Linode", select your plan, then click the "Add this Linode!" button

   

2. Next, in the Linode Dashboard, click Deploy an Image:

   

3. Next, Select CentOS 7 64bit image, SwapDisk and choose a password for your root account:

   

4. Finally, Boot your Linode:

DirectAdmin Installation

1. SSH to your Linode server.
2. Install updates for your server:

   yum update -y
   

3. Install DirectAdmin:

   yum install -y perl-DBI
   wget -O setup.sh http://www.directadmin.com/setup.sh
   chmod 755 setup.sh
   ./setup.sh
   

Configuration

1. Fix quotas problem Linode CentOS 7 uses ext4 instead of xfs, so we must fix the problem. Set use_xfs=0 in /usr/local/directadmin/conf/directadmin.conf and restart DirectAdmin, then run the following commands:

   ln -s /dev/sda /dev/root
   

   Edit /etc/rc.d/rc.local and add this line:

   ln -s /dev/sda /dev/root
   

   Then run:

   chmod +x /etc/rc.d/rc.local
   /sbin/quotaoff -a; /sbin/quotacheck -avugm; /sbin/quotaon -a;
   

   Reboot your server.

2. Adding IPv6

   If your server has an IPv6 address, you can add it to DirectAdmin. First, enable ipv6 in directadmin.conf file:

   nano /usr/local/directadmin/conf/directadmin.conf
   

   Set extra_spf_value= ip6:xxxx::xx:xx:xxx:xxxx (Note the space after the = character, and replace xxx with your IPv6 address)

   Set ipv6=1

   Restart DirectAdmin; when restarted, go to IP Management and add your new IPv6:

   Then, link the IPv6 to your IPv4 by clicking on the IPv4 and selecting IPv6 to link.

Conclusion

Now you have your DirectAdmin running in your Linode Server. To optimize performance and improve security, see this guide.
