Update CentOS / DirectAdmin Server with custombuild 2.0

Here is how to use latest version of custombuild 2.0 . The commands for custombuild 2.0 are basically identical to custombuild 1.1 and 1.2, so all this stuff should look familiar.

Notice: At the time of this writing (2012-03-14) custombuild 2.0 doesn't support upgrading from php 5.2 to 5.4. If you're upgrading from php 5.2 to 5.4 please use custombuild 1.2.

cd /usr/local/directadmin
wget http://files.directadmin.com/services/custombuild/2.0/custombuild.tar.gz
tar xvzf custombuild.tar.gz
cd custombuild
./build

edit options.conf file, selecting whatever you want to upgrade and what version numbers... then run:

./build update_data

to update to latest version

./build update
./build clean

to see what updates are available for your system run:

./build versions

to see what your option.conf file is compiled as:

./build options

or

./build used_configs

to install everything on option.conf:

./build all d

to install a specific app:

./build APPNAME

to update everything possible:

./build update_versions
