Plesk >= 12.0 multi lsphps configuration for LSWS

You can create lsphp5x one by one from LSWS Admin console. If you prefer using the command line instead of the GUI tool, you can edit the LSWS configuration file (usually /usr/local/lsws/conf/httpd_config.xml) by adding the following to the <extProcessorList>… </extProcessorList> section:
