Installation modes of Talend Installer and Talend Studio Installer

This section provides information about the different installation modes that Talend Installer and Talend Studio Installer can run in.

Note that the log files generated during the installation can be found in /tmp/.

Note also that, once Talend Installer has completed the installation of the products, a directory (called Talend by default) is created with sub-folders for each Talend product.

The following installation modes are available:

Graphical mode: allows full interactivity through a graphical user interface.
Text mode: provides full interactivity with users in the command line. It is equivalent to any GUI mode but the pages are displayed in text mode in a console.
Example of text mode where the user enters the --mode text option from the command line:
```
<TalendInstallerDirectory> ./<TalendInstallerFileName-linux64-installer.run> --mode text
```
Information noteNote: This installation mode is only available on Unix platforms. It is automatically used if no graphical mode is available but it also can be forced using the --mode text command.
Unattended mode: is especially useful for automating the installation processes. This silent mode will perform an unattended installation that will not prompt the user for any information.
For more information about the available options of the unattended mode, see Talend Installer and Talend Studio Installer unattended mode available options.

Procedure

To perform an Unattended installation, write a simple .txt script in which you will define the options values.

Information noteNote: For a complete list of values, use the help command.
```
mode=unattended
debugtrace=/home/user/Talend_install_files/debugInstall.txt
licenseFile=/home/user/Talend_install_files/license
installdir=/home/user/Talend
installType=full
installStyle=easy
```
In this example, the script details the silent installation of the Server type (full type).

The installation directory that will be 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 type installation for example: 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. For more information about the available parameters and their values, enter help in the console.
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>. An unattended installation is performed.
To install Talend products as services via the Installer, you are required to run the application as Administrator OR to disable User Account Control. For more information on these installation modes, please refer to the online Bitrock documentation.
