Dear all,
I developed a small tool to montitor my solar system and write the data
into a database in golang.
The go tool just runs on foreground and log to STDOUT.
I want to run that now on my system using maybe an rc script so it is
started automatically on startup.
Using FreeBSD 14.3.
Starting it work perfectly fine.
But I have problems with the restart command.
If I execute:
service monitorsolar restart
Stopping monitorsolar.
kill: 14894: Operation not permitted
monitorsolar already running? (pid=14894).
But is is running:
ps auxw |grep solar
root 14894 0.0 0.0 13856 1964 - Ss 07:50
0:00.00 daemon: monitorsolar[14895] (daemon)
gitlab_deploy_solar 14895 0.0 0.0 1275980 26404 - S 07:50
0:00.02 ./monitorSolarApi -config /usr/local/etc/monitorsolar
I think it is maybe a problem with how permissions are dropped. I
executed all commands as root.
Maybe someone sees the problem in the rc script and can give me a tip:
#!/bin/sh
# PROVIDE: monitorsolar
# REQUIRE: DAEMON NETWORKING
# KEYWORD: shutdown
#
# Add these lines to /etc/rc.conf.local or /etc/rc.conf
# to enable this service
#
# monitorsolar_enable (bool): Set to NO by default
# Set it to YES to enable monitorSolar.
# monitorsolar_args (string): Custom extra arguments for monitorSolar
# monitorsolar_user (string): Set to gitlab_deploy_solar by default
# The user to run the server (make sure
user exists)
# monitorsolar_group (string): Set to gitlab_deploy_solar by default
# The group to run the server (make
sure group exists)

monitorsolar_precmd()
{
# Ensure log directory exists
install -d -g "${monitorsolar_group}" -o "${monitorsolar_user}"
"$(dirname "${logfile}")"
}
monitorsolar_start()
{
# redirect stdout to logfile and drop root permissions
${command} \
-H \
-o "${logfile}" \
-t "${name}" \
-P "${pidfile}" \
-u "${monitorsolar_user}" \
sh -c "cd '${workingdir}' && ./monitorSolarApi -config

}
