Using the installers unattended installation mode

Use the unattended installation mode to automate the installation processes. Instead of prompting the user for information at each step of the process, you provide the full installation details in a text script.

Before you begin

Make sure you complete the prerequisites listed in Talend Installers specific prerequisites.

Procedure

To perform an unattended installation, write a simple .txt script in which you will define the options values.
Example
The following script details an unattended installation using the server installation mode of Talend Installer:
```
mode=unattended
debugtrace=/home/user/Talend_install_files/debugInstall.txt
licenseFile=/home/user/Talend_install_files/license
prefix=/home/user/Talend
installMode=server
```
The following script details an unattended installation using the Talend Studio Installer:
```
mode=unattended
debugtrace=/home/user/Talend_install_files/debugInstall.txt
licenseFile=/home/user/Talend_install_files/license
prefix=/home/user/Talend
```
Information noteTip: For a complete list of options, use the help command. For more information about these options, see Talend Installer Unattended mode available options for Linuxfor Windows andTalend Studio Installer Unattended mode available options for Linuxfor Windows.

The installation directory created is called Talend and the license file used is located in the /home/user/Talend_install_files directory.

You can also create a script for a custom installation mode for Talend Installer. In this case, specify in your script the products and modules to install as well as the configuration information of these products. For example, the enable-components parameter allows you to do a comma-separated list of these products, while the tacPort parameter allows you to specify the port to use for Talend Administration Center.
Launch the silent installation using the --optionfile <filename> command, where <filename> is the name of the script which contains the list of pairs <key>=<value>.
To install Talend products as services using an installer, you must run the application as Administrator or disable User Account Control. For more information on these installation modes, see the Bitrock documentation.
