INSTALL DIRECTADMIN ON CENTOS SERVER

DirectAdmin VPS / Server

Login to your server as root
and run

Code:
yum -y update

Before installing DirectAdmin, there are some basic programs that you’ll need. The following are the typical commands used before we install DirectAdmin.

On Rehat/Fedora/CentOS:

Code:
yum install wget gcc gcc-c++ flex bison make bind bind-libs bind-utils openssl openssl-devel perl quota libaio libcom_err-devel libcurl-devel gd zlib-devel zip unzip libcap-devel cronie bzip2 db4-devel cyrus-sasl-devel perl-ExtUtils-Embed

Once its complete

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

you will be prompted for a client ID number, license ID number, and hostname.

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

Important: The hostname should not be the same as the primary domain name. e.g. server9x.com is not a valid hostname, where myserver.server9x.com is. Having the same host/main domain name will cause e-mail and FTP problems. Also, please make sure the hostname resolves once you setup DNS.

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:

Code:
/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:

Code:
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:

Code:
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:

Code:
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

Code:
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
