Obsolete Info

Some of these things may be actively misleading, proceed with caution. This is being kept around to aid in writing the improved documentation above.

here's the final procedure you should follow (for installing service "SERVICE" (mysql) on host "HOST" (deleuze)):

1. create local user SERVICE in /etc/passwd:

2. create Kerberos principal:

kadmin.local -q "addprinc -policy service -randkey SERVICE/HOST"

3. export user's keys to /etc/keytabs/SERVICE.HOST and chmod the file properly:

kadmin.local -q "ktadd -k /etc/keytabs/SERVICE.HOST SERVICE/HOST"
chown SERVICE:wheel /etc/keytabs/SERVICE.HOST
chmod 440 /etc/keytabs/SERVICE.HOST

4. create OpenAFS user SERVICE.HOST

      pts cu SERVICE.HOST.hcoop.net

5. create OpenAFS group "SERVICE" if it doesn't exist, and add SERVICE.HOST to it:

pts cg SERVICE

6. modify service's init script in /etc/init.d/ in the following way:

start-stop-daemon --start --pidfile $PIDFILE \
 --exec /usr/bin/k5start -- -U -b -f /etc/keytabs/SERVICE.`hostname` \
 -K 300 -t -p $PIDFILE \
 <The original start command>

start-stop-daemon --start --pidfile /var/run/SERVICE/k5start-SERVICE.pid \
  --exec /usr/bin/k5start -- -U -b -K 300 -t -p /var/run/SERVICE/k5start-SERVICE.pid \
  -f /etc/keytabs/SERVICE.`hostname`
sleep 2

start-stop-daemon --stop --pidfile /var/run/SERVICE/k5start-SERVICE.pid
rm -f /var/run/SERVICE/k5start-SERVICE.pid

7. You give permissions in AFS space to group "SERVICE", or to user "SERVICE.HOST" if specific instance is important. (Mostly, you just add permissions to "SERVICE").
