init.d script and installation folder for production systems

[Iván Martínez]

Hello all,
I have a couple of questions about installing Zotonic in a production
server:

- Where do you install Zotonic in production servers, in "/home/
zotonic"? (I suppose there isn't a single answer, I just want to know
what other administrators do).

- I need Zotonic to start after system reboot. Does anyone have a
"init.d" script, or uses another method to achieve this?.

Thank you,
Ivan

that's what I did.

I wrote a basic init.d-script for debian 6.0 today. Supports start, stop,
status and restart. It's not very polished at the moment, but does the job.
Could mail it to you, if interested.

Hi Ivan,

In theory Zotonic can be installed anywhere. But it is more common to install in /home/.

@Michael,

I would love a copy of your init.d script. I still can't restart server using ./bin/zotonic restart (hosted at Webfaction).

Best,
Daniel

I just use zotonic's native zotonic command with an init header:

arjan@srv1:~$ cat /etc/init.d/zotonic
#!/bin/sh -e

### BEGIN INIT INFO
# Provides: zotonic
# Required-Start: $postgres $local_fs $remote_fs $network $time
# Required-Stop: $postgres $local_fs $remote_fs $network $time
# Should-Start:
# Should-Stop:
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Zotonic default
### END INIT INFO

/usr/bin/sudo -u zotonic /home/zotonic/zotonic/bin/zotonic $1

Thank you Arjan and Michael. I have installed in "/home/zotonic" and
I'm using Arjan's script, but I get the following error:

[root@masterion zotonic]# /etc/init.d/zotonic start
Starting zotonic zoton...@masterion.com
/usr/bin/env: escript: No such file or directory
make[1]: *** [compile] Error 127
make: *** [gen_smtp] Error 2
/home/zotonic/zotonic/src/scripts/zotonic-start: line 24: erl: command
not found

Starting with zotonic.sh works fine.

By the way, there seems to be a problem with file permissions in
Zotonic 0.7.1, the files below don't have execution permission:
zotonic/src/scripts/zotonic-status
zotonic/doc/zotonic.sh
Also, why is "zotonic.sh" in the doc folder?.

Thank you,
Ivan

I think you need to add the path to erlang in your initscript.
I use
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin

My erlang is installed in /usr/local/bin

zotonic.sh sets
ERL="/usr/local/bin/erl"

It seems you have installed erlang, where I have, so this works.

It has in my installation.

Afaik zotonic.sh is deprecated. But I'm not sure about this.

Yes. The idea is that you use the 'bin/zotonic' command, which is a
replacement for the old zotonic.sh. It should probably be removed..

I still would like to make zotonic into a debian package. But I'm not
really sure how this would work, with the sites et cetera..

I've seen this same issue, while being on a windows system. All
src/scripts/* files had x perm, except zotonic-status.

Since it was so easy to fix, I didn't investigate it further...

[Arjan Scherpenisse]

True. I just fixed it and pushed to master.

My PATH seems to be correct, I can run erl with zotonic user:

[root@masterion init.d]# su zotonic
[zotonic@masterion init.d]$ $PATH
bash: /usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/
home/ivanmr/bin: No such file or directory
[zotonic@masterion init.d]$ erl
Erlang R14B04 (erts-5.8.5) [source] [rq:1] [async-threads:0] [hipe]
[kernel-poll:false]

Eshell V5.8.5 (abort with ^G)

The confusing thing is that this doc still refers to zotonic.sh:
http://zotonic.com/documentation/777/deployment#comment-275

May I suggest you first make a "make install" command to install
Zotonic as a system service?. That would be very helpful.

Try setting it in the initscript. The PATH, that's available to these scripts
might be different from your "normal" PATH. Just add the line below to the top
of the script after the LSB-comments. If it does not work, I was wrong. Still
worth a try imo.

Best,
Michael

[Iván Martínez]

Yes, you were right, I had to set the path in bin/zotonic. Now I can
do "/etc/init.d/start" and "/etc/init.d/stop" to start and stop the
service. The problem is it doesn't start on system boot yet. I have
added the service with chkconfig as follows:

[root@masterion bin]# chkconfig --add zotonic
[root@masterion bin]# chkconfig zotonic on
[root@masterion bin]# chkconfig
...
postgresql 0:off 1:off 2:on 3:on 4:on 5:on 6:off
...
zotonic 0:off 1:off 2:on 3:on 4:on 5:on 6:off

PostgreSQL starts but Zotonic doesn't, while both seem to be
configured the same way. I haven't seen any error report, not even in /
access/log (there is an empty "access.log.2011..." file there).

Thank you,
Ivan

Is there anything in priv/sasl? (sasl.log and zotonic.log)

Regards,
Atilla

[Iván Martínez]

Nothing at all. Should I start looking about system services failing
to start, rather than Zotonic issues?.
Ivań

[Atilla Erdődi]

Yes, it's probably a good idea. As far as I know, there is always
*some* information present in the sasl logs, when the erlang runtime
starts up - so it might not even be started at all.

I made it work in my CentOS 6 by modifying the end of Arjan's file as
follows:

...
### END INIT INFO
# chkconfig: 2345 90 10
su - zotonic -c "/home/zotonic/zotonic/bin/zotonic $1"

The chkconfig line is important to make sure it boots after PostgreSQL
and shuts downs before it. "sudo" didn't work for me, I had to replace
it with the "su" command above. At least this is what worked in my
CentOS 6 system.

So let's recapitulate, first you must create zotonic user and group
with its home folder as follows:

groupadd -r zotonic
useradd -r -m -g zotonic zotonic

Become zotonic user ("su zotonic") and as such install Zotonic inside
"/home/zotonic", so Zotonic's root folder is "/home/zotonic/zotonic".

Edit "/home/zotonic/zotonic/bin/zotonic". Add the following line right
after the header comments:

PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin

Make sure Zotonic's scripts have the proper permits, some may not:

chmod 755 /home/zotonic/zotonic/src/scripts/*

Become root and create "/etc/init.d/zotonic" file, which is Arjan's
file (below) with my modifications (above). Make sure it has the right
permits:

chown root.root /etc/init.d/zotonic
chmod 755 /etc/init.d/zotonic

Install the service:

chkconfig --add zotonic

And again, this is what worked in my CentOS 6.

Hi Iván,

thanks a lot for this little how to :)
