$ jruby -S gem install trinidad_init_services
When the gem is installed the user must launch the installation process:
$ jruby -S trinidad_init_service
This installer guides you through the configuration process and generates a init.d script if you are on a Unix system or creates the service if you are on a Windows box.
You can optionally provide a YAML configuration file with defaults specified
trinidad_init_service command. An example configuration file :
app_path: "/home/trinidad/myapp/current" ruby_compat_version: RUBY1_9 jruby_home: "/opt/jruby" java_home: "/opt/java" output_path: "/etc/init.d" pid_file: "/home/trinidad/myapp/shared/pids/trinidad.pid" log_file: "/home/trinidad/myapp/shared/log/trinidad.log" jsvc_path: "/usr/bin/jsvc" trinidad_options: "-e production" trinidad_name: Trinidad trinidad_service_id: Trinidad # on Windows (defaults to :trinidad_name) trinidad_service_desc: Trinidad Service Description # on Windows (optional)
You can then run the installer like so:
$ trinidad_init_service --defaults trinidad_init_defaults.yml
If any of the required options are not provided in the configuration file, then the installer will prompt you for them. If you're running this as part of an environment initialization script than use the --no-ask option or provide only the defaults file path on the command line (make sure all required options are there) :
$ jruby -S trinidad_init_service trinidad_init_defaults.yml
NOTE: Do not confuse the defaults.yml "configuration" file with Trinidad's own configuration (config/trinidad.yml) file used when setting up the server !
To run Trinidad as a daemon jsvc is used. Some distributions provide binary packages of JSVC but not all, for these we do bundle JSVC's sources and try to compile the binary during configuration for you. However please note that to build JSVC on Unix you will need :
- an ANSI-C compliant compiler (GCC is good) and GNU Make
- Java SDK installed (a JRE installation is not enough)
When the installation process finishes you can use the script generated to launch the server as a daemon with the options start|stop|restart, i.e:
$ /etc/init.d/trinidad restart
By default, the Trinidad server process will run as the same user that ran the
/etc/init.d/trinidad start command. But the service can be configured to run
as a different user. The preferred method for doing this is the
attribute in the configuration YAML (or it's corresponding value at the prompt).
app_path: "/home/trinidad/myapp/current" # ... run_user: trinidad # ...
This causes the the server to run with non-root privileges (it essentially executes
sudo -u run_user jsvc ...).
On some platforms, however, it may be required that you use the JSVC
This can be configured with the
JSVC_ARGS_EXTRA environment variable, like this:
JSVC_ARGS_EXTRA="-user myuser" /etc/init.d/trinidad start
It not recommended that you mix the
-user flag with the
run_user option !
Manage as every other rc.d, assuming
update-rc.d -f /etc/init.d/trinidad defaults
you can uninstall using :
$ [sudo] trinidad_init_service --uninstall /etc/init.d/trinidad
Open the Services panel under Administrative Tools and look for a service called Trinidad (or whatever name you have chosen).
To remove the service you're going to need the service id (name), than run :
$ trinidad_init_service --uninstall Trinidad
