Re: [Zotonic-Usr] Cannot add site

[Arjan Scherpenisse]

You might have encountered a bug. The addsite command was change lately
to include a check whether or not zotonic is running.

What does the following command give you:

erl_call -name zotonic09@localhost -a "zotonic status"; echo $?

The output should be: ok0

Hi  Arjan

What does the following command give you:

erl_call -name zotonic09@localhost -a "zotonic status"; echo $?

The output should be: ok0

Somehow changed hostname:

cd bin

./zotonic start

Starting zotonic zoton...@helentana-dev.local

./zotonic addsite

Zotonic is not running. You need to start zotonic first to use this command.

erl_call -name zoton...@helentana-dev.local -a "zotonic status"; echo $?

erl_call: can't get_hostent(helentana-dev.local)

[Amiramix]

It may not be enough to change hostname. It wasn't in my case at least. Zotonic required that the full qualified name is returned, e.g. that both forward and backward dns entries are present.

First of all check what "host YOURIP" returns. It should return the hostname. You can also try "nslookup YOURIP", e.g.:

host 192.168.1.68
or
nslookup 192.168.1.68

Where YOURIP or 192.168.1.68 in the example above is the IP of your server. With dig you could do:

dig youhostname.com
dig -x YOURIP

In Erlang shell, after starting Zotonic, you can try net_adm:localhost(). and inet:gethostname().

Please post outputs of those commands. I don't remember what the values were in my case but I do remember that until I sorted them out to return proper values the Erlang node couldn't resolve the hostname properly and be communicated with by commands like zotonic-addsite.

I think we ought to have some more diagnostics built in to try to pin point the issue when

there's a node we fail to communicate with, as this is rather basic, to be able to do anything else.

Ah, so I went ahead and opened an issue for it:  https://github.com/zotonic/zotonic/issues/423

[Arjan Scherpenisse]

This issue started showing when I started using "erl_call" for certain
checks in the Zotonic scripts (as opposed to starting a node and then
using the rpc functions in zotonic.erl)

Maybe erl_call works differently?

[Grzegorz Junka]

Yes, I think so, because as I said erl_call didn't work for me until my
host had a proper DNS name that could be forward and back resolved. Just
an entry in the host file wasn't enough.

[Alexey Marunin]

Hi, Amiramix!

First of all check what "host YOURIP" returns. It should return the hostname. You can also try "nslookup YOURIP", e.g.:

host 192.168.1.68
or
nslookup 192.168.1.68

$ host 134.0.117.105

105.117.0.134.in-addr.arpa domain name pointer helentana-dev.ru.

 

In Erlang shell, after starting Zotonic, you can try net_adm:localhost(). and inet:gethostname().

HOSTNAME=helentana-dev.ru zotonic debug

1> inet:gethostname().

{ok,"helentana-dev"}

2> net_adm:localhost().

"helentana-dev.ru"

 

[Amiramix]

Could you please start zotonic with the standard starting script WITHOUT setting the HOSTNAME variable:

./start.sh (from the Zotonic main folder)

Then do again inet:gethostname(). and net_adm:localhost().

The command zotonic addsite will in the end call erl_call, which will try to communicate with the node started from ./start.sh to add the new site. When erl_call is run it doesn't have the HOSTNAME environment variable set and this is probably why it can't communicate with the Zotonic node. The hostname must be set properly for the whole system, so it can be visible by erl_call as well, not only when starting the Zotonic site.

Hi Alexey,
I still think this is a problem with the domain name of the Erlang node. Specifically the script says that you started the node on zoton...@helentana-dev.local whereas net_adm:localhost(). returns helentana-dev.ru. Where does the .ru come from?

Could you please do a quick test and run this command:

erl_call -name zoton...@helentana-dev.local

and

erl_call -name zoton...@helentana-dev.ru

If erl_call can connect to the node then it doesn't return anything, and it returns an error if it can't.

And also, can you temporary edit zotonic/src/scripts/helpers/zotonic-debug script and add echo in front of the command, e.g.:

echo $ERL -env (...)

Then try to call ./start.sh as usually. This time instead of starting the node it will print to the terminal the command and its parameters that it's using to start the node.

Then I edited config-file - set hostname as helentana-dev.ru

Now example site successfully load :) But no picture... I think because of old version ImageMagick

Last question - why erl_call not found? 

[Amiramix]

In my case erl_call could be found in this path:

/usr/local/lib/erlang/lib/erl_interface-3.7.5/bin/erl_call

whereas all other erlang binaries are in this path:

/usr/local/bin/

I think location of erl_call may be system specific. Did you compile Erlang yourself or downloaded as a package? I would try something like:

cd /
find . | grep erl_call

You could also try "man erl_call" to see if the system knows anything about it.

[Andreas Stenius]

As Greg pointed out, it's located in the bin dir of erl_interface.

On my system, it's in /usr/lib/erlang/lib/erl_interface-3.7.7/bin so a slightly different version...

Online docs for erl_call is here: http://www.erlang.org/doc/man/erl_call.html

And it was those docs that hinted for me where to look for it ;)

//Andreas

2012/9/27 Amiramix <li...@gjunka.com>

[Arjan Scherpenisse]

Strange, I always assumed erl_call was on the path. I guess we should do
some magic to determine where erl_call is when its not on the path...

I take it It's on your path then... ?

Strange indeed. Perhaps if you installed it using some package manager, that the packager added a symlink or something for erl_call to a bin directory that's in your path.. ?

Yes, I'm using the esl-erlang packages from Erlang solutions..

Seems that erl_call is not always installed…. at least not in the same path when doing a 'make install'
Arjan, how did you install erlang on your machine?

- Marc

[Alexey Marunin]

Hi Amiramix

In my case erl_call could be found in this path:

/usr/local/lib/erlang/lib/erl_interface-3.7.5/bin/erl_call

whereas all other erlang binaries are in this path:

/usr/local/bin/

I think location of erl_call may be system specific. Did you compile Erlang yourself or downloaded as a package? I would try something like:

cd /
find . | grep erl_call

You could also try "man erl_call" to see if the system knows anything about it.

 

I updated my Erlang according by official documentation:

wget http://www.erlang.org/download/otp_src_R15B02.tar.gz 
gunzip -c otp_src_R15B02.tar.gz | tar xvf - 
cd otp_src_R15B02 
export ERL_TOP=$PWD 
./configure 
make 

make install

And I have erl_call in path:

/usr/local/lib/erlang/lib/erl_interface-3.7.8/bin/erl_call


To run erl_call easy I create symlink:
ln -s /usr/local/lib/erlang/lib/erl_interface-3.7.8/bin/erl_call /usr/local/bin/erl_call

Now:

zotonic@helentana-dev:~$ erl_call -name zoton...@helentana-dev.local; echo $?

erl_call: can't ei_gethostbyname(helentana-dev.local)

1

zotonic@helentana-dev:~$ erl_call -name zoton...@helentana-dev.ru; echo $?

0

 

[Amiramix]

So, the hostname is now OK. But as I understood from previous emails addsite does work for you now, doesn't it?

The lack of pictures is probably due to the fact that module Bootstrap isn't enabled by default. At least that was the reason for me.

[Alexey Marunin]

Hi Amiramix

Yes, now all commands work fine. Seems problem was in the incorrect hostname

 

The lack of pictures is probably due to the fact that module Bootstrap isn't enabled by default. At least that was the reason for me.

 

How check status of this module? And how enable it?

I try to build latest ImageMagick on my server - but not enough RAM to do it. I think because of 64bit-architecture (on the same system but x86-architecture ImageMagick successfully built). So may be your advice helps me

 

[Alain O'Dea]

Hi Alexey:

You can enable modules under System | Modules in Admin.  It is also accessible at http://example.com/admin/modules where example.com is your domain name :)

Drop me a line if you need assistance.

Best,
Alain

[Alexey Marunin]

Hi Alain

This module activated in my admin. But pictures still don`t display correctly

 

 

[Alain O'Dea]

Hi Alexey:

I have run into this a few times.

Do you have the module for your site activated?  For me it is simply called "blog zotonic site".  If this is deactivated, you will not get a functional site.

Do you also have Zotonic Base activated?

I hope you don't mind the trial and error approach.  It can be quite difficult to know the specific issue sometimes :)

Best,
Alain

[Alexey Marunin]

Yes, green light :)

I know sometimes difficult questions have a simple solution :)

[Dawid Figiel]

OK, I found the reason...

sudo su
echo "127.0.0.1 yoursite.local" >> /etc/hosts

This '.local' is confusing ;)

Good night!

[Arjan Scherpenisse]

I just committed some changes which deal with the issues in this thread:

- Zotonic now uses code:priv_dir to locate the erl_call binary within the distribution, so that should always work (famous last words)
- Zotonic now runs using -sname by default; which prevents these hostname issues people were getting.  No more need to add foo.local to your hosts file!

Hopefully this makes everybody's life easier.

There was a change recently regarding this ( https://github.com/zotonic/zotonic/commit/62b80da1d712ce1b91802450a5642870ad5d7f40 )

Commit message was:

core: Make configurable whether we run with -name or with -sname

This fixes the fact that Zotonic always required a FQDN and the
"zotonic shell" command was not working reliably.

Zotonic now defaults to running with "-sname". To use "-name", set the
envirnoment variable ZOTONIC_DISTRIBUTED=true. Distributed
mode *really* requires a proper FQDN as returned by "hostname -f".

A better way to determine if Zotonic is running has also been added,
using "erl_call", and we determine more reliably where the "erl_call"
binary is located.

[Arjan Scherpenisse]

This is an interesting one.

Do you start with "zotonic start" or "zotonic debug"?

With either of those, can you open src/scripts/zotonic-start (or zotonic-debug) and, on the last line of the file add an "echo" in frond of the call to $ERL?

so the line becomes something like:

echo $ERL -env ERL_MAX_PORTS $MAX_PORTS +P $MAX_PROCESSES +K $KERNEL_POLL -pa $PA $NAME_ARG $NODENAME@$HOSTNAME -boot start_sasl -config $ZOTONIC/priv/erlang.config -heart -detached -s zotonic

and then run zotonic start, copypaste that line here.

Hmm, come to think of it, does the -sname part need a hostname (-sname foo@bar) at all, or without? (just -sname foo)
Erlang gurus, are you listening? :)

From: http://erlang.org/doc/man/erl.html

-sname Name

Makes the Erlang runtime system into a distributed node, similar to -name, but the host name portion of the node name Name@Host will be the short name, not fully qualified.

This is sometimes the only way to run distributed Erlang if the DNS (Domain Name System) is not running. There can be no communication between nodes running with the -sname flag and those running with the -name flag, as node names must be unique in distributed Erlang systems.

-name Name

Makes the Erlang runtime system into a distributed node. This flag invokes all network servers necessary for a node to become distributed. See net_kernel(3). It is also ensured that epmd runs on the current host before Erlang is started. See epmd(1).

The name of the node will be Name@Host, where Host is the fully qualified host name of the current host. For short names, use the -sname flag instead.

Thanks!

In the chatroom we figured out what's wrong. I pushed a fix.

Hello all,
What is the proper way of setting ZOTONIC_DISTRIBUTED to true in a file, so one doesn't have to do it when starting the server?
Thank you,
Ivan

This has to be part of the shell's environment that is starting zotonic.

You can do it in a few ways:

.profile or .bashrc of the user running zotonic:
export ZOTONIC_DISTRIBUTED=true

or when you use sudo when starting zotonic: (e.g. from an init script)

/usr/bin/sudo -u zotonic ZOTONIC_DISTRIBUTED=true -i /home/zotonic/zotonic-0.9/zotonic/bin/zotonic $@
