Step C: Install the Elemental Live software

About Installer Options

To install Elemental Live, you run the installer. The installer has options that control the way the installer works:

• Action options instruct the installer to perform an action. For example, --cleandb instructs the installer to clean out the database.

• Skip options instruct the installer to omit specific prompts. For example, --skip-tz instructs the installer to skip the timezone prompt.

To display built-in help about all the options, log in with the elemental user credentials, then enter this command at the Linux command line:

[elemental@hostname ~]$ sudo sh ./elemental_live_cpu_2.25.4.12345.run --help

The skip-all Installer Option

The installer has a --skip-all option that skips all the prompts and performs the default choice for all options.

You should only use this option after you have followed the following procedure, and you have read the built-in help carefully.

The --skip-all option means that the installer won't present prompts. It will perform some actions using default information.

Setting up OCR Conversion in Versions 2.22.0 to 2.23.0

The installer for Elemental Live versions 2.22.0 to 2.23.0 includes an option to set up the feature to convert captions using OCR conversion. (For information about the OCR feature, see Support for OCR Conversion in the AWS Elemental Live User Guide.)

To set up this feature

Note

The Elemental Live node must have a connection to the internet. It needs this connection because the installer must download the OCR libraries from the internet. These libraries are language dictionaries used in the conversion.

If the node doesn't have an internet connection, consider upgrading to a version after version 2.23.0. Newer versions of Elemental Live include more options for installing the OCR feature.

Run the installer with these options:

• With the --install-ocr option. You won't be presented with prompts to set up OCR. Instead, the installer will automatically set it up.

• You can include or omit the --skip-all option, depending on whether you want to be presented with prompts for other features.

To omit the feature

If you don't want to set up this feature, run the installer with these options:

• Without the --install-ocr option. The installer won't set up the OCR feature.

• You can include or omit the --skip-all option.

Setting up OCR Conversion in Versions 2.23.1 and later

The installer for Elemental Live version 2.23.1 and later includes several options to set up the feature to convert captions using OCR conversion. (For information about the OCR feature, see Support for OCR Conversion in the AWS Elemental Live User Guide.)

Setting up this feature involves three steps:

• Downloading the OCR libraries from the internet. These libraries are language dictionaries used in the conversion

• Installing the libraries on the node

• Enabling the OCR feature

To set up the feature on a node with access to the internet

Run the installer with these options:

• With the --install-ocr option. The installer will download the libraries from the internet, install them on the node, and enable the OCR feature. You won't be presented with prompts to set up OCR.

• You can include or omit the --skip-all option, depending on whether you want to be presented with prompts for other features.

To set up the feature on a node without internet access

1. Download the OCR libraries file live-ocr-tesseract-data.zip

   Don't unzip the file after you download it.

2. Use SCP to move the zipped file to a location on the Elemental Live node that you are setting up. For example, move to this location:

   /home/live-ocr-tesseract-data.zip

3. Run the installer with these options:

   • With the --install-ocr-zip option. This option includes a parameter for the folder where you copied the libraries file. For example:

     -- install-ocr-zip /home/live-ocr-tesseract-data.zip

     You won't be presented with prompts to set up OCR.

   • You can include or omit the --skip-all option, depending on whether you want to be presented with prompts for other features.

To omit the feature

If you don't want to set up this feature, run the installer with these options:

• Without the --install-ocr option. The installer won't install or enable the OCR feature.

• With the --skip-ocr option. If you don't include this option, you will be presented with prompts to install OCR, even though you didn't include the --install-ocr option.

• You can include or omit the --skip-all option, depending on whether you want to be presented with prompts for other features.

The Install Procedure

1. Use SCP to move each Elemental Live software installer (.run file) to the /home/elemental directory on the appropriate virtual machine. Use the elemental user credentials.

2. From the VMware vSPhere client, choose Open Console and access the VM with the elemental user credentials.

   You are logged in at the home directory (/home/elemental).

3. Decide which options you want to include with the installer. You can include options in the command to automate some of the installation. To display built-in help about all the options, enter this command:

   [elemental@hostname ~]$ sudo sh ./elemental_live_cpu_2.25.4.12345.run --help

4. Run the installer as follows. Use the actual file name of your .run file, rather than the example below.

   [elemental@hostname ~]$ sudo sh ./elemental_production_live_2.25.4.12345.run  options

5. Follow the prompts. This table specifies the prompts that appear when you don't include any options for the installer.

   Prompt	Action
   Do you agree to these terms	This prompt appears after you have paged through the EULA (End User License Agreement). Enter Yes or No. (You must enter Yes to continue.)
   Enter this server's Hostname	Type the hostname of this hardware unit. For example, live-01
   Would you like to configure eth1	If you type No, you can configure eth1 in the next phase of the configuration
   The firewall for this system is currently disabled. Would you like to enable it?	If you type No you can set up the firewall in the next phase of the configuration
   Is this machine a part of or intended to be a part of a Conductor Live 3 cluster?	Type Yes or No
   Will this machine require use of SNMP alerts?	Type Yes or No
   Will this machine be ingesting RTMP?	Type Yes or No
   Will this machine ingest MPEG-TS over UDP (ports 5000-5100)	Type Yes or No
   Will this machine serve files using Windows file-sharing (Samba/CIFS)?	Type Yes or No
   Will this machine be an NTP server?	Type Yes or No
   Enable conversion of eligible captions using OCR technology?	Type Yes or No. For information about requirements for this feature, see Setting up OCR Conversion in Versions 2.23.1 and later.
   Select time zone ('n' for more)	Enter the time zone you want to show on the web interface of the nodes. This setting does not affect activity via SSH or via the REST API.
   Do you wish to enable authentication?	Type Yes or No if you want to set up so that users must log in to use Elemental Live
   For security purposes, we require that you change the default password.	This prompt is shown if you are still using the default password. We recommend that you create a strong password: Minimum 8 characters At least one uppercase letter, at least one lowercase letter, at least one number, and at least one symbol.
   Would you like to start the Elemental service now?	Type Yes

   The software is installed. Finally, this message appears:

   Installation and configuration complete!

6. Take a snapshot of the VM, as described in the CentOS 7 Virtual Manager online help.

7. Start a web browser and start the Elemental Live web interface by typing the following:

   https://<hostname>

   Make sure the web interface displays.
