Running Redis in daemonized form and using Upstart to manage it doesn't work
I've written an Upstart script for Redis as follows:
description "Redis Server"
start on runlevel [2345]
stop on shutdown
expect daemon
exec sudo -u redis /usr/local/bin/redis-server /etc/redis/redis.conf
respawn
respawn limit 10 5
I then configure redis via it's redis.conf to:
daemonize yes
All the documentation and my own experimentation says Redis forks twice in daemonized form and "expect daemon" should work, but the Upstart script is always holding on to the PID of the former parent (PID - 1). Has anyone got this working?
Answer
The following upstart config seems to be working for me, with upstart 1.5 on ubuntu 12.04, with redis.conf daemonize set to yes:
description "redis server"
start on (local-filesystems and net-device-up IFACE=eth0)
stop on shutdown
setuid redis
setgid redis
expect fork
exec /opt/redis/redis-server /opt/redis/redis.conf
respawn
