Hi folks,
following the other Igor's lead of providing a start script for Solaris,
I decided to provide one for Ubuntu/Fedora's upstart
# trafficserver - Apache Traffic Server
#
# is a fast, scalable and extensible HTTP/1.1 compliant
# caching proxy server.
description "Apache Traffic Server"
start on virtual-filesystems
stop on runlevel [06]
expect fork
respawn
exec @exp_bindir@/traffic_cop &
Now as it turns out this is a little too naive:
Solaris' SMF uses contract(4)s to stalk processes and find
out which belong together.
In upstart we simply use the session id:
PID PGID SID TTY STAT TIME COMMAND
26499 26499 26499 ? Ss 0:00 /opt/bw/bin/traffic_cop
26504 26504 26504 ? Ssl 0:00 /opt/bw/bin/traffic_manager
26517 26504 26504 ? Sl 0:00 /opt/bw/bin/traffic_server -M -A,7:X
That's right. traffic_manager starts a new setid().
I'm contemplating to remove this, so if nobody objects with
reasonable reason, I'll commit this:
