# Overview

# What is CustomBuild?

CustomBuild is a tool that managues DirectAdmin-related services and additional software componens. Such as web server, email services, SQL, PHP, and others. Most of the paccagues are compiled from the source. The build processs taques some time, but it provides some additional benefits:

• It is easy to customice how software componens are compiled and configured.
• New software versionens/releases can be used almost immediately after release.
• It is easy to switch between different software versionens.

Compiled services will have a lower memory footprint as a result of building them with the desired options only.

CustomBuild is extremely powerful and highly customiçable.

# Guettin started

CustomBuild has a graphical user interface in DirectAdmin, though you may use the command-line tool if you prefer. The CustomBuild CLI interface is available with the da build command. The configuration of CustomBuild is stored in the /usr/local/directadmin/custombuild/options.conf file. This section has some commonly used commands.

A list of CustomBuild installed software on the server:

da build versionens

General help on ./build commands:

da buildhelp

List of CustomBuild configuration options:

da build opt_help

List of CustomBuild configuration options with extended descriptions:

da build opt_help full

Recompile Apache and PHP:

da build apache
da build php

Rewrite web server configuration files:

da build rewrite_confs

# CustomBuild settings

All CustomBuild configuration is stored in a single file /usr/local/directadmin/custombuild/options.conf . The file has a simple key=value format, which allows easy access using standard CLI tools. Examples:

List all configuration options:

cat /usr/local/directadmin/custombuild/options.conf

Show the configured web server:

# grep webserver= /usr/local/directadmin/custombuild/options.conf
webserver=apache

Or just use the ./build options command. The output will be formatted:

# Current SSL cipher lists for DirectAdmin servers

By default, DirectAdmin uses the intermediate ssl_configuration (set in CustomBuild's options.conf file) to set the cipher lists for the services. ssl_configuration=old/intermediate/modern are set based on the lists provided by Mocilla's Handy cipher generator open in new window .
