2. DirectAdmin installation steps for CentOS

Before installing must install add some necessary packages as follows:

yum -y update
yum install -y net-tools vim-enhanced gcc-c++ perl wget psmisc systemd-devel libdb-devel perl-DBI xfsprogs zip unzip bzip2 deltarpm ncurses-devel ncurses ntpdateSau khi đã install các package, bây giờ chỉ chuẩn bị client ID, license ID để cài đặt (Money payment)

– Download the installer

wget http://www.directadmin.com/setup.sh

– chmod to be able run

chmod 755 setup.sh

./setup.sh

– Start installing DA

It will then ask you to enter the client ID, license ID. During the installation process, you should note that when choosing the installation type, you should choose custombuild 1.1. And when filling hostname must be full: server.domain.com yes not just domain.com.
When the installation is complete, because the DA uses port 2222, the default iptables will close this port. So need to stop iptables

# service iptables stop
# chkconfig iptables off

After installation, the DA will be saved in /usr/local/directadmin.

In which the most important folder is /custombuild, you can change the default configuration when installing in this. Custombuild can be found at http://forum.directadmin.com/showthread.php?t=29824
default user and password are: admin and admin;

If it still doesn't work, go to ssh to change the password for the admin user with the following command: passwd admin

– Command to change getLicense to direcadmin

cd /usr/local/directadmin/scripts
./getLicense.sh 123 1234 ( Client ID: 123 and License ID: 1234 )
service directadmin restart
