HRM daemon with System-V-like init systems#

Warning

Please make sure to only follow EITHER the instructions given in this chapter here for installing the daemon on System-V or upstart based systems, OR the ones for systemd, but NEVER BOTH.

If unsure, use the instructions here!

Install the init script#

To launch the HRM daemon at boot, we are providing an init script in $HRM_RESRC/sysv-init-lsb/hrmd which can be placed in /etc/init.d/. The script makes use of the LSB init functions and therefore requires /lib/lsb/init-functions to be available in your distribution (which is true for Ubuntu and RHEL systems, as well as most other major up-to-date Linux distributions).

For installing the init script, type the following commands in a shell:

sudo cp -v $HRM_RESRC/sysv-init-lsb/hrmd /etc/init.d/hrmd
sudo chmod +x /etc/init.d/hrmd

Start / stop the daemon at boot / shutdown#

ubuntu Ubuntu: To set up the appropriate run-level links for starting and stopping the daemon during boot and shutdown, use this command:

sudo update-rc.d hrmd defaults

This will configure your system to run the init script in the default run-levels. Please note that issuing this command does NOT actually start the daemon until the next reboot. To start it right now follow the steps in the section below.

RHEL

Recent versions of RHEL-based sysmtems do not install the Linux Standard Base (LSB) specification by default, as they are using systemd init. Therefore we recommend using the systemd unit file, described in HRM daemon with systemd.

Note

If you want to use the classical init script approach nevertheless, please make sure the package redhat-lsb.x86_64 is installed, i.e. by running:

sudo dnf install redhat-lsb.x86_64

Start manually#

Make sure to set the proper value of SUSER in /etc/hrm.conf (see Server).

Start a shell and type:

sudo /etc/init.d/hrmd start

If the queue manager started correctly, you should see:

Forking background process...
Reporting stdout to '/var/log/hrm/log.txt' and stderr to '/var/log/hrm/error_log.txt'.

To check if the queue manager daemon is running, use the status argument. In case the service is operational, it will show a message like this:

[ ok ] HRM is running (/var/www/hrm/bin/hrm_queuemanager), PID: 1234.

The queue manager can be started, stopped and restarted by using:

sudo /etc/init.d/hrmd start
sudo /etc/init.d/hrmd stop
sudo /etc/init.d/hrmd restart
