How to Installation Direct admin on CentOS 5,6

how to install Direct Admin on a clean installation of CentOS 5 and 6. The procedure is exactly the same on both these operating systems and with both 32-bit and 64-bit versions. It is very important to start off with a clean installation, as the DirectAdmin installer will take care of all software components you need.

Do you meet the system requirements?

• A clean and compatible OS install: check the installation requirements to ensure you've got a supported OS.
• At least one external IP address is required (NAT/LAN-based systems will NOT work)
• SSH installed, gcc, g++, openssl-devel installed. Common pre-install commands

If you have purchased your license directly from DirectAdmin.com, sign into your client account at https://www.directadmin.com/clients and click the "view" link next to your license. Verify that the server IP address and operating system is correct. Also make sure that the license is Active and Verified (if it isn't, you need to contact Direct Admin support). If you have problems with a license obtained through Woktron Web Hosting, please contact Woktron Support.

1. update CentOS to the latest version (currently 5.8 or 6.3)

yum update

2. install DirectAdmin

Begin by installing the required dependencies for Directadmin:

yum install wget gcc gcc-c++ flex bison make bind bind-libs bind-utils openssl openssl-devel perl quota libaio libcom_err-devel libcurl-dev gd zlib-devel zip unzip libcap-devel cronie

Continue by downloading the DirectAdmin setup routine using wget, set file permissions to writable with chmod and finally startup the setup routine by issuing the ./setup.sh command:

wget http://www.directadmin.com/setup.sh
chmod 755 setup.sh
./setup.sh

After the setup routine starts you will be presented with a number of options. You should have your license details ready.

When the install routine has completed, you should be ready to login to your newly installed control panel via: http://xx.xx.xx.xx:2222(where xx.xx.xx.xx is your IP address or domain name). 2222 is the port DirectAdmin normally communicates on. It is important to keep this port open in your firewall

In case you forgot your admin password enter the following:

cd /usr/local/directadmin
./directadmin i

3. update custombuild:

After having DirectAdmin succesfully installed it is now time to secure your server. A good first step would be to install the CSF Firewall. It is also important to periodically update your server. This can be done by issuing the following commands:

cd /usr/local/directadmin/custombuild
./build clean 
./build update 
./build update_versions

4. Dealing with RPM errors

When installing RPMs, errors can sometimes occur. Don't panic, solving them is usually easy. If you didn't know what to install during your RedHat installation, you might have installed a few services, such as apache and sendmail. These services must be removed before the rpm will be able to be installed.

For example, lets say you are trying to install exim and you get the following:

rpm -ivh exim-3.36-2.i386.rpm
  Preparing...                         ########################################### [100%]
  file /somefile from install of exim-3.36-2 conflicts with file from package sendmail-8.1
  ...

This would mean that sendmail is already installed on your server and you must remove it. This can easily be accomplished by running the following:

rpm -e --nodeps sendmail

Then you will be able to install your rpm. This follows for other services such as apache, apache-devel, wu-ftp, php, MySQL and so forth. If you need to figure out if you already have a service installed, you can run

rpm -q servicename

or

rpm -qa | grep substring

Where substring is just a word. For example, using "apache" might return:

rpm -qa | grep apache
apache-fp-1.3.27-2
apache-fp-devel-1.3.27-2
apache-fp-manual-1.3.27-2

5. Troubleshooting

If you are having trouble with RPMs hanging, please take a look at:
