Temos um trabalho do Upstart em /etc/init/private-api.conf , contendo:
# start when server starts
start on runlevel [23456]
# Stop when server shuts down/reboots
stop on shutdown
#Respawn the process if it crashes
#If it respawns more than 10 times in 5 seconds stop
respawn
respawn limit 10 5
#expect fork
script
cd /home/ubuntu/private-api && exec java -jar -Dspring.profiles.active=stage private-api-SNAPSHOT.jar > private-api.log 2>&1
end script
O próximo comando que eu preciso disparar é:
sudo initctl reload-configuration
Depois disso, devo executar o serviço usando o seguinte comando:
service private-api start/stop/restart/status
Recebo o seguinte erro quando faço :
initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused
Descobri que no Ubuntu 16.04 o Upstart não é usado e agora mudei para o Systemd , e que o arquivo Systemd precisa estar no local - /etc/systemd/system , com a extensão do arquivo .service . Após o qual executar o serviço systemd após 2 comandos precisam ser disparados:
sudo systemctl daemon-reload
sudo systemctl start xyz.service
Estou me referindo aos seguintes links:

Aqui está o que consegui até agora usando as referências acima:

Eu recarreguei meu serviço Systemd:
sudo systemctl daemon-reload
Mas quando eu verifico o status do serviço, recebo erros absolutos de caminho:

Alguém pode me ajudar a converter meu atual script .conf de upstart?
