Munin on an ISPConfig3 server

[Hans]

I try to get munin up and running on a new Debian/Xen ISPConfig3 server.

Munin can write data into the default htmldir, which is /var/www/munin. So that's ok.

However after changing the htmldir within /etc/munin/munin.conf, munin can't write it's data into the directory i've defined. Here is the output of my current /etc/munin/munin.conf:

cat /etc/munin/conf

dbdir /var/lib/munin
htmldir /var/www/www.example.com/web/munin
logdir /var/log/munin
rundir /var/run/munin

After defining the new htmldir, i did:

mkdir -p /var/www/example.com/web/munin
chown munin:munin /var/www/example.com/web/munin
/etc/init.d/munin-node restart

I also did:
chmod 755 /var/www/example.com/web/munin
But no luck.

Is there something i miss here?
Do i need to create a specific setting in ISPConfig3 for the website?

***EDIT *** Here are some outputs of the munin log files:

cat munin.graph.log

Unable to graph /var/lib/munin/localdomain/localhost.localdomain-vmstat-sleep-g.rrd: Could not save png to '/var/www/www.example.com/web/munin/localdomain/localhost.localdomain-vmstat-week.png'

What's the output of

ls -la /var/www/www.example.com/web/munin/

?

Hi Falko,
thanks for your reply.
The output is:

drwxr-xr-x 2 munin munin 4096 2010-01-30 13:33 .
drwx--x--- 6 web2 client1 4096 2010-01-30 14:00 ..

Hans,

Try using the true paths ( /var/client/clients...... )
I have munning up and running, and used the above paths

[Hans]

Thanks for your reply Edge, but i tried that also already.
Munin can only put its data in /var/www/munin which is the default directory on Debian...

This is how my working munin.conf looks like:

dbdir /var/lib/munin
htmldir /var/clients/client1/web1/web/monitoring
logdir /var/log/munin
rundir /var/run/munin

As you can see. For me it's working also working in /var/clients/client1/web1/web/monitoring

[Hans]

Hi Edge, thanks for your help.
I think in principle the true paths are better indeed, so i changed it again.
After changing, my configuration file, i did: /etc/init.d/munin-node restart

Within /etc/munin/munin.conf, now i have:

dbdir /var/lib/munin
htmldir /var/www/clients/client1/web2/web/munin
logdir /var/log/munin
rundir /var/run/munin

Short after that a message appears in /var/mail/root, which says:

The output of:
ls -la /var/www/clients/client1/web2/web/munin is:

drwxr-xr-x 2 munin munin 4096 2010-01-30 13:33 .
drwx--x--- 6 web2 client1 4096 2010-01-30 14:00 ..

I don't understand why munin can't write its data into my htmldir.
As far as i see it has to do something with the permissions, but what can i do?
Maybe it has nothing to do with it, but did you also installed Jailkit or not?

[edge]

Yes I do have Jailkit on my system.

My ls -la /var/clients/client1/web1/web/monitoring

drwxr-xr-x  3 munin munin    4096 2009-03-04 21:40 .
drwxrwxrwx 28 web1  client1  4096 2010-01-30 17:46 ..

-rw-r--r--  1 munin munin    3472 2009-03-04 21:40 style.css

[Hans]

Ok, then both we have Jailkit installed.

For munin:munin we have the same, which is: drwxr-xr-x
For web1:client1 you have drwxrwxrwx (chmod 777), while i have: drwx--x--- which was generated automaticly by ISPConfig 3.

As far as i see, this is the only difference, isn't it ?
I hope there is another solution, because i try to avoid chmod 777.

I also would like to know, which options did you enable for your website in ISPConfig 3?

[edge]

For web1:client1 you have drwxrwxrwx (chmod 777)

No.. It's 755 (created and owned by Munin)

I also would like to know, which options did you enable for your website in ISPConfig 3?

All I have set for that site is PHP to Fast-CGI, and site is Active.
