Re: ubuntu serve - cyrus fails to start

[lowpass <zijn.digital@xxxxxxxxx>]

I backed up:
/etc/imapd.conf
/etc/cyrus.conf
/etc/default/cyrus-imapd

and ...

# apt-get install cyrus-common-2.4 cyrus-imapd-2.4

And everything is just fine now. Spooky.

Bron: after you mentioned creating the dirs in a script before cyrus starts up i remembered there's an "init-helper" script at /usr/lib/cyrus/bin that includes that functionality. It was while looking at that that i realised i was missing an armload of scripts, then also some binaries. Weird, weird day.

And thanks for the replies! I guess i should apologise for the noise. I realise this may seem all "dog ate my homework" but i swear i haven't the faintest idea what happened. If you hear about anyone else having mysterious deinstalls like that do let me know.

I had done an upgrade of some packages. I listed those at the end of my first message. I don't think any of them had anything to do with cyrus, though. But i'd rebooted the server afterwards; i think that's why the problem with cyrus began to appear.

# zgrep cyrus-imapd /var/log/apt/

I had already tried that. Nothing at all.

# sh -x /etc/init.d/cyrus-imapd start
+ LC_ALL=C
+ export LC_ALL
+ PATH=/sbin:/usr/sbin:/bin:/usr/bin
+ PATH=/sbin:/usr/sbin:/bin:/usr/bin
+ NAME=cyrmaster
+ DAEMON=/usr/sbin/cyrmaster
+ PIDFILE=/var/run/cyrmaster.pid
+ DESC=Cyrus IMAPd
+ test -x /usr/sbin/cyrmaster
+ exit 0

Good idea about shell debugging, thanks. In any case, it's failing because cyrmaster no longer exists. :-(

Bron: no, nothing in syslog. I'd checked that first thing.

I'm mystified as to what has happened. I think i'll try to (re)install those packages and see what comes of it. But, realistically, it looks like i should rebuild the server.

You told us that you had run some apt commands prior to this problem, but you haven't told us what they were.  If you tried to install something which "replaces" cyrus-imapd, you may have forced its removal.

What does "zgrep cyrus-imapd /var/og/apt/*" show?

This is saying that the packages have been selected for removal. But, a) I certainly have not done so; and b) they already seem to be gone. And i see nothing at all about them in appt's history logs.

Deep breaths.

Thanks for the quick response, Bron. The symlink is ok.

# ls -l /var/run
lrwxrwxrwx 1 root root 4 Oct 18  2014 /var/run -> /run/

I tried creating the dir myself as you suggested:

# mkdir /run/cyrus
# chown cyrus /run/cyrus/
# service cyrus-imapd start

[nothing]

I tried removing the --quiet flag from the startup script with same (non) results.

What about the pid? As i understand, it's not cyrus that creates that on startrup. In any case, it's NOT being created. From /etc/init.d/cyrus-imapd:

NAME=cyrmaster
PIDFILE="/var/run/${NAME}.pid"

I've posted a message on the Ubuntu forum as well, as i've a feeling the problem is not with cyrus. I was hoping, though, that another cyrus user might have run into this.

I do have socket and lock dirs under /var/lib/cyrus but they were last modified several years ago and seem to be left over from some other config. Other dirs there have seen more recent activity. Everything seems to be pointing towards the socket & lock dirs being created under /run but there's nothing there.

 

/run is a tmpfs which gets created fresh on each reboot.

 

Cyrus starts as user 'cyrus' and has no permission to create the directories it needs.

 

Your init script should create the directories - but if you moved them somewhere other than where the package expects them to be, then it won't create intermediate directories for you.

 

So, here's the thing:

 

1) double check that /var/run and /run are the same place - they're mostly a symlink in recent Debian/Ubuntu systems.  If not, I suggest that you audit your configuration to be all in /var/run or all in /run (probably a good idea anyway for more consistency.

 

2) run these commands as root:

 

mkdir /run/cyrus

chown cyrus /run/cyrus

 

3) either put those commands in a startup script that runs before Cyrus starts, or edit the init script for Cyrus - though note that if you edit the init script, you'll have to re-apply those edits on upgrade.

 

Unfortunately, this isn't something we can fix in the Cyrus binaries.  They try to create the directories, but they just plain don't have permissions to do so at that stage of the process.

 

Regards,

 

Bron.
