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
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 cronieContinue 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.shAfter the setup routine starts you will be presented with a number of options. You should have your license details ready.
(start installation routine:)when using a Virtual Private Server (VPS) you should select the respective virtual network port:***************************************************** * * Have you run the pre-install commands? CTRL-C if not. * http://help.directadmin.com/item.php?id=354 * ***************************************************** Please enter your Client ID : xxxxx Please enter your License ID : xxxxx Please enter your hostname \(server.domain.com\) It must be a Fully Qualified Domain Name Do *not* use a domain you plan on using for the hostname: eg. don't use domain.com. Use server.domain.com instead. Do not enter http:// or www Enter your hostname (FQDN) : xxxxx.xxxxx.com Client ID: xxxxx License ID: xxxxx Hostname: xxxxx.xxxxx.com Is this correct? (y,n) : y The following ethernet devices/IPs were found. Please enter the name of the device you wish to use: eth0 xxx.xxx.xxx.xxx eth1
venet0:0 (the usual option) venet0:1If unsure enter the following in commandline and see which ETH adapter is using your public IP address:
ifconfig
(installation routine continued:)Enter the device name: xxx Is xxx.xxx.xxx.xxx the IP in your license? (y,n) : y DirectAdmin will now be installed on: Enterprise 5.7 Is this correct? (must match license) (y,n) : y You now have 2 options for your apache/php setup. 1: customapache: end-of-life software. Includes Apache 1.3, php 4 and frontpage. **Not recommended**. Will not work with newer OSs. Limited tech support. 2: custombuild 1.1: newer software (recommended). Includes any Apache version, php 4, 5, or both in cli and/or suphp. Frontpage not available. Post any issues with custombuild to the forum: http://www.directadmin.com/forum/forumdisplay.php?f=61 Enter your choice (1 or 2): 2 You have chosen custombuild 1.1. 2011-11-11 14:47:00 http://files.directadmin.com/services/custombuild/1.1/custombuild/build Resolving files.directadmin.com Connecting to files.directadmin.com|:80 connected.

Below you will find what options you have when selecting a custom setup of DirectAdmin:
In case you forgot your admin password enter the following:
Would you like the default settings of apache 2.2 and php 5 cli? (y/n): N Would you like to have PHP4 or PHP5 as default? (4/5): Would you like to have PHP5? (yes/no): Would you like to have PHP5 as CLI or CGI? (cli/cgi): Would you like to have PHP4? (yes/no): Would you like to have ionCube? (yes/no): Would you like to have Zend Optimizer? (yes/no): Would you like to have an ability to update/instal MySQL using CustomBuild? (yes/no): Which version of MySQL you would like to have? (5.0/5.1): Which version of Apache you would like to have? (1.3/2.0/2.2): Would you like to have an ability to update/instal Exim using CustomBuild? (yes/no): Would you like to have an ability to install Dovecot? (yes/no): Would you like to have an ability to install/update phpMyAdmin using CustomBuild?

(yes/no): Would you like to have an ability to install/update Atmail Open webmail using CustomBuild? (yes/no): Would you like to search for the fastest download mirror? (y/n):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
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 sendmailThen 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 substringWhere 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
