How to set "HOME" env. variable?

[BorisTrnka]

Hello, is there a way to define "HOME" environment variable for the NCPA agent (ncpa_listener service)? I tried few standard ways (default for service, ...), but no luck.

Current ENV:

root@sandbox1:/usr/local/ncpa# /usr/lib/nagios/plugins/nagios_plugins/check_ncpa.py -H localhost -M 'plugins/print-env.sh'
SHLVL=1
TCL_LIBRARY=/usr/local/ncpa/tcl
JOURNAL_STREAM=9:190959
_=/usr/local/ncpa/ncpa_listener
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin
INVOCATION_ID=36d74fe4a26a441283541d6cd8533ca9
LANG=en_US.UTF-8
TK_LIBRARY=/usr/local/ncpa/tk
PWD=/

Thanks.

On a system with systemd you can do it the following way:

1. Create a drop-in config file /etc/systemd/system/ncpa_listener.service.d/ncpa_listener.conf and define your environment file:

   [Service]
   EnvironmentFile=-/etc/sysconfig/ncpa_listener

   Example of the environment file cat /etc/sysconfig/ncpa_listener

   MY_VAR="my value"

2. systemctl daemon-reload
3. You should see your dropin-config with systemctl cat ncpa_listener

   
   # /run/systemd/generator.late/ncpa_listener.service
   # Automatically generated by systemd-sysv-generator

/etc/systemd/system/ncpa_listener.service.d/ncpa_listener.conf

[Service] EnvironmentFile=-/etc/sysconfig/ncpa_listener

3. Restart ncpa_listener service `systemctl restart ncpa_listener`
4. Check if it works
