Install DirectAdmin on Amazon AWS A-Z Guide

This guide shows you how to install and configure DirectAdmin on Amazon EC2.


  • Active AWS Account.
  • AWS Security Group open on ports 80,995,143,465,53,2222,443,35000-35999,110,1194,993,22,21,25,53,587
  • Basic linux knowledge
  • DirectAdmin Licnese

Lunch EC2 instance

Login to AWS Console.

Go to EC2 Dashboard, and click “Lunch Instance” button:

Lunch EC2 instance

Choose an CentOS 7 (AMI):


Choose any Instance Type that suit your needs, add storage, configure Security Group then lunch your server:

Configure Instance
Add SSDEC2 key


To begin, login to your AWS EC2 serevr via SSH

1. Update your CentOS and install some basic programs

2. Enable SSH for root account

Set PermitRootLogin yes
Set AllowTcpForwarding no

Edit this the authorized_keys to allow login via root account

Then delete the lines at the begining of the file that say “COMMAND….” until you get to the words ssh-rsa

Restart SSH

3. Set your hostname

Assume that I’m using the domain, and you want your server hostname set to

Check if the /etc/hostname shows the hostname

We also edit /etc/hosts to make the hostname point to the server IP

then add at the end where is your server public IP

AWS will reset the hostname everytime the server reboot, so we need to fix this.

and add preserve_hostname: true below the syslog_fix_perms

Then reboot the server

4. Activate Quotas

On CentOS 7, xfs is used by default and Quotas are not activated, so you need to enable them manually

add quota options rootflags=usrquota,grpquota into the end of  GRUB_CMDLINE_LINUX line, it will look like this

Make a backup

Generate a new configuration file:

Restart the server, the root directory will be mounted with required options. We can check by running this command

5. Add network eth0:0
By default, AWS EC2 use private IP for eth0, to install DirectAdmin, we need to use the public IP

Enter the following content

where is your AWS Public IP, then restart the network

If you wish to you IPv6, set your eth0 live below:

6. Setup DirectAdmin

And follow the instructions. Note when you asked for the network, enter eth0:0


Since EC2 runs on a LAN/NAT and behind the firewall, we need to do some config.

Enable LAN

Add this value lan_ip=yyy.yyy.yyy.yyy where yyy.yyy.yyy.yyy is your AWS Private IP
Link the Private IP to your Public IP using the DA Linked IP feature

  • Add the LAN IP to DA’s IP manager. Don’t assign it to any Users or Domains.
  • View the details of the external IP: Admin Level -> IP Manager -> Click the public/external IP.
  • Link the internal IP to the external IP: Select the LAN IP from the drop down.
  • Only select Apache, do not select DNS

Restart DirectAdmin


Open ports for FTP

If you use ProFTPD, edit it’s configure file:

Add after PassivePorts: MasqueradeAddress where is your AWS Public IP

Add rule to the iptables

add $IPTABLES -A INPUT -p tcp –dport 35000:35999 -j ACCEPT below the ftp section, like this
