The scl Utility

Overview

To manage software packages in a Software Collection Library (SCL) environment via the command line, use the scl utility.

EasyApache 4 (EA4) uses SCLs for PHP versions. SCLs allow multiple concurrent software packages to reside on your file system. You can use this utility if you run multiple websites that require different PHP versions.

For more information about SCLs, read our Introduction to EasyApache 4 documentation.

The scl Utility

The scl utility uses the following syntax:

scl option action library 'command'
Variable Description Possible values Example
option The desired option.
  • -l, --list — List the server’s available software package collections.
  • -h, -help — Display the scl utility’s help output.
 -l
action The action to perform.
  • enable
  • register
  • deregister
 enable
library The SCL.
  • A valid PHP software collection.
  • An absolute filepath to the software collection.
    Important:
    If you use the register or deregister variable, you must pass the SCL’s absolute filepath. The SCLs reside in the /opt/cpanel/ea-phpxx/root/usr/bin directory, where xx represents the ea-php version.
 ea-php70
'command' The command to run in the SCL environment. For a list of valid commands, run the php --help or pecl --help commands. 'php -m'

Example

To view the ea-php70 SCL modules, run the following command:

scl enable ea-php70 'php -m'

The output will resemble the following example:
