             Summary: Solr installer: Make check for used tool "service" compatible with SuSE Linux like OpenSuse or SLES
                 Key: SOLR-11853
                 URL: https://issues.apache.org/jira/browse/SOLR-11853
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
    Affects Versions: 7.2
         Environment: SuSE Linux (SLES & OpenSuSE)
            Reporter: Markus Mandalka
            Priority: Minor
             Fix For: master (8.0), 7.3, 7.2.2


On current SuSE Linux releases like SLES or OpenSuSE the Solr installer stops with the error message "Script requires the 'service' command".

This happens because before installation the installer checks if the used command "service" exists by its option "service --version".

The command line option "--version" doesn't exist for "service" on current SuSE Linux stable releases.

Since the command "service" is there and has an option "--help", this option can be used as additional fallback.

So in the pull request i extended the check with "service --help" as second check / fallback before printing this error and exiting.
