Install On The Command Line

We only recommend this method for advanced users who are familiar with database management and the command line.
Configuration and database issues can prevent you from using this method. We recommend that you perform a backup first.
This installation method doesn't perform checks for InnoDB or database setup.

The installation script uses the following syntax:

php -f bin/installer.php –- [options]

Defaults
The script enables non-interactive mode (-n or --non-interactive) and performs an upgrade (-u or --upgrade) by default.

You can use these options with the installation script:

Option	Description
`-c` or `--config`	Provide configuration data in the JSON format. Use this with the `-n` or `--non-interactive` option. For more on how to use this, see Supplying configuration data below. Added in WHMCS 7.10 We added this option in WHMCS version 7.10.
`-h` or `--help`	View help information.
`-i` or `--install`	Perform a new installation.
`-n` or `--non-interactive`	Don't require user input while the script runs.
`-s` or `--status`	Provide status information about the installation's files and databases.
`-u` or `--upgrade`	Upgrade an existing installation.
`-v` or `--verbose`	Run the script with verbose output.

If you use the -c or --config option, you must supply configuration data in the JSON format. For example:

echo '{"admin":{"username":"name","password":"12345luggage"'}} | php -f bin/installer.php – -i -n -c

The script uses your input to create a configuration.php file for the installation.

You can configure two arrays:

Array	Description
`admin`	Provide information for the installation's administrator account using the `username` and `password` parameters. Warning Exercise caution using the `admin` array to supply passwords. It could pose a security risk.
`configuration`	Provide configuration information for the WHMCS installation. For a list of parameters to use, see Restoring WHMCS.
