load at bootup
How would I go about starting james on bootup (Linux)?
I'm using Fedora core 1 if that's any help!
Thanks,
Daniel Perry.

Since SysVInit scripts run as root, no password is necessary.
I see that you are using Microsoft Outlook Express for e-mail. You may want
to get some books on linux if you are new to it.

On *nix, root is necessary for privileged ports. There are ways around that
using ip forwarding. If you do so, you can use su in the script to start
James as a non-privileged user.
For SE Linux, one might use roles.

Is it possible to start James service using the startup script on Linux
under some user, created specifically for James mail server?

RE: load at bootup
Posted by Daniel Perry <d....@netcase.co.uk>.
Yep,
But that is what phoenix.sh does after stopping the process (but is failing
to do).
As i said: "service james stop" does delete the file, but "shutdown -r now"
doesnt.
For now it is working with the modified phoenix.sh start section.
I will continue messing with these scripts when i have some spare time, to
try and determine what is going on. My guess is that "shutdown -r now" is
inpatient, and is killing the script somewhere.

phoenix.home -> This is regular expression and the dot means "any
character".
phoenix\.home -> Means the dot character.
So in the first the following will resolve true;
phoenix.home
phoenix/home
phoenix+home
phoenixAhome

It should be listed in /var/log/boot.log
Also, the phoenix script outputs to $PHOENIX_TMPDIR/phoenix.console, but I am
not sure how that relates to James.

I know that there is none during startup, and assume shutdown is the same.
Looking at the phoenix script, it is a two phased shutdown, send a "kill
SIGTERM" first, wait a while and then "kill SIGKILL", and the latter will
just remove the process from memory without necassry letting it shutdown
completely. In any event, the .pid file is removed by the script.
The phoenix script defaults to 5 second delay, prior to the SIGKILL, but can
be set with the $PHOENIX_KILLDELAY variable.

RE: Checking PHOENIX_PID for validity
Posted by Daniel Perry <d....@netcase.co.uk>.
I'm running fedora 1.
I have exactly as you say - a script i put in init.d (which does start, stop
and restart)
I used chkconfig to install and set runlevels for the james script. It
appears to have done it's job, as there are Sxx and Kxx symlinks in the
rcN.d directories.
The script works fine used through the "service" command. "service james
stop" which uses the etc/init.d/james script works fine!
Is there any way of finding out what is happening on shutdown (this is a
remote server, so i dont get any screen output!)
I'm not sure what is happeneing, but i figure it must be calling the stop
script, but for some reason it either isnt running properly, or it's getting
killed before completing (does linux do this? is there a timelimit for stop
calls?)

I am not sure which OS you are running, but the standard mechanism for
startup
and shutdown under System V is that you have a "initi.d" directory
containing
the script itself, which understand "start" and "stop" argument.
Then there is a "rcN.d" containing the symbolic link to the
"init.d/phoenix-server.sh", and is "prepended" with an "Sxx" or a "Kxx".
N stands for the RunLevel, and those are slightly different on each OS. On
my
Linux 3 is for Multiuser text mode, and 5 is for MultiUser X Desktop and 6
for shutdown.
xx is a number to control the order in which things are started or shutdown.
So you look through the existing list and figure out how soon or how late in
the sequence it must start or stop.
So you do something like;
ln -s /etc/init.d/phoenix-server.sh /etc/rc3.d/S95phoenix.sh
ln -s /etc/init.d/phoenix-server.sh /etc/rc5.d/S95phoenix.sh
ln -s /etc/init.d/phoenix-server.sh /etc/rc6.d/K10phoenix.sh
I hope this helps.

RE: Checking PHOENIX_PID for validity
Posted by Daniel Perry <d....@netcase.co.uk>.
I agree. It's making assumptions like this that caused the problem in the
first place (origional assumption being phoenix.pid exists means it's
running....)
I think my assumption of it running if there's a process under the recorded
id (small chance of it being somthing else) and having "phoenix.home" in it
(very very small chance of it being somthing else).
This is the fist bit of shell script i've ever written, and i'm amazed it
works...
>> (should it not be phoenix\.home really)
Why? (i'm new to this!) is it just escaping? or somthing else?
>>Sounds as if you down have it registered to be stopped during shutdown.
Ok, that was my guess...
But again, being new to this, how do you do that? I thought having it
registered as a service, it would be done for me...
[root@p4-7138 root]# chkconfig --list | grep james
james 0:off 1:off 2:off 3:on 4:on 5:on 6:off
I thought that meant it would be be turned off for halt (0) and reboot (6).
Correct me if i'm wrong :)

I only see one problem with the one that is in CVS compared to the one
that was offered. The CVS one does not take in account that linux reuses
the process numbers, and therefore there can be some other process that
use the same pid, the one offered tries to take this into account with
the usage of grep phoenix.home (should it not be phoenix\.home really)
Especially if the main problem is after a unclean shutdown of the james
server and then an reboot of the machine this would be the case.
I have some time ago downloaded a shell script some time ago that was
designed to be used for the init.d (with start,stop,restart,status, etc)
This script has the same problem, and I was baffled before I discovered
it why my servers would not start at a reboot. I ended up having to code
in not just checking that the process was living,but that it was a java
process that had some parameters that identified it as my server.

RE: load at bootup
Posted by Daniel Perry <d....@netcase.co.uk>.
This was not fun to solve. For some reason, the phoenix.pid file is getting
left behind. So when it reboots is doesnt startup - phoenix.sh just says
it's started! i was being fooled by the shell script :(
Anyway, i found a couple of ways round this - simply change
/etc/init.d/james so that the start part deletes the pid file!
but this is sloppy as you could start it twice using service start.
So, the better way is to alter phoenix.sh so it doesnt just look for the
file - it verifies that the pid file is a process! This is my first attempt
at shell coding, so it's a bit unprofessional looking, but it works!
Simply replace the origional code:
if [ -f $PHOENIX_PID ]
then
echo "Already Running!!"
exit 1
fi
With:
if [ -f $PHOENIX_PID ]
then
phpid=`cat $PHOENIX_PID 2>/dev/null`
piddata=`ps $phpid | grep phoenix.home 2>/dev/null`
if [ "$piddata" != "" ]
then
echo "Already Running!!"
exit 1
fi
fi
Not sure wether the phoenix team would be interested in doing somthing
similar so as to avoid this kind of problem!
Daniel.

Ok, i went down this service approach (tried both approaches - symlink to
phoenix, and the script noel sent).
It works a treat with "service james start", "service james stop".
BUT, if i reboot, it doesnt start up properly. (this only if it was running
at reboot).
Phoenix does start because if you try to start james again it says it's
already running! However, it isnt listening on any ports. stop it and start
it and it's fine.
Note, it also doesnt generate any log files.
To clarrify:
if james is running fine, and i do:
# shutdown -r now"
when the server reboots, james is running, but doesnt listen!
if james is running fine, and i do:
# service james stop
# shutdown -r now
when the server reboots, james is running, and is listening!
Any ideas? cos i'm stumped!
Thanks,

I use the attached. Place it, or a symlink, in /etc/rc.d/init.d. Then run
$ chkconfig --add james
to have it installed. See "man chkconfig" for other options. The easy way
to access the scripts is the service command, e.g.,
$ service james [start | stop | restart]
phoenix.sh has some options not yet supported in this script, but doesn't
integrate with the runlevel level scheme.
