NAME

Footprintless::Service - Performs an action on a service.

VERSION

version 1.19

SYNOPSIS

# Standard way of getting a service
use Footprintless;
my $service = Footprintless->new()->service();

$service->stop();

$service->start();

$service->status();

$service->kill();

DESCRIPTION

Manages services. Allows you to start, stop, check the status of, and kill services. Additional actions can be configured as well.

ENTITIES

A simple service (the most common case) can be defined:

service => {
    command => '/opt/foo/bar.sh',
    pid_file => '/var/run/bar/bar.pid'
}

A more complex service might be defined:

service => {
    actions => {
        debug => {command_args => "jpda start"},
        kill => {command_args => "stop -kill"},
        status => {use_pid => 1, command_name => 'tomcat'},
    },
    command => '/opt/tomcat/catalina.sh',
    hostname => 'tomcat.pastdev.com',
    pid_command => 'ps -aef|grep "/opt/tomcat/"|grep -v grep|awk \'{print \$2}\'',
    sudo_username => 'tomcat',
}

In this case, an additional action, debug, was added, kill was redefined as a special case of stop, and status was redefined to use the pid (ex: kill -0 $pid). Also, the pid is found via command rather than a file.
