Forum OpenACS Q&A: installation failure of openacs on a server running Ubuntu 8.04

1: installation failure of openacs on a server running Ubuntu 8.04

Posted by Gilmar Sequeira Martins on 06/10/09 11:53 AM

Hi everybody,

As you seem to deal with very accurate points, maybe you could help me. I've installed openacs on a server running Ubuntu 8.04 using the following commands (detailed here => http://openacs.org/xowiki/ubuntu) :

apt-get install postgresql-8.2

then

apt-get install openacsapt-get install openacs

and at the end

dpkg --configure aolserver4

Unfortunately, the connection is impossible (see the result at http://92.243.19.47/) and I don't know what I have to check (nssock section of config.tcl ? but what to change ?). In case it could help, here's the section nssock of config.tcl :

#---------------------------------------------------------------------
#
# Socket driver module (HTTP) -- nssock
#
#---------------------------------------------------------------------
ns_section ns/server/${server}/module/nssock
ns_param timeout 120
ns_param address $address
ns_param hostname $hostname
ns_param port $httpport

Thank you for any suggestions, ideas and clues !

Gilmar

Gilmar,

First, welcome to the community!

Second, i moved the thread over to OpenACS QA, fits better.

Third, as for your problem, there seems to be a more fundamental problem than configuration here.

a) Please, as a first step, verify whether an aolserver process is running (presumably, there are two, a default one fired up by the aolserver4 package and the openacs-specific one) ... and report back:

ps ax | grep nsd

b) Have a look at the /usr/share/openacs/log/error.log file and post what you find (the last 15-20 lines).

Hi Stefan,

It's always good to be welcome ! Thank you.

the command ps ax | grep nsd gives back this :

9932 pts/0 S+ 0:00 grep nsd

The last 20 lines of /usr/share/openacs/log/error.log are the following :

Gilmar,

The good news is, the basics are fine. The problem is that the the nsd process is limited to listening to request on the localhost *alone*:

[10/Jun/2009:09:53:16][9119.3063868304][-nssock:driver-] Notice: nssock: listening on 127.0.0.1:8000

Assuming that you access the machine remotely (e.g. through the 95.*.*.* address), this won't work then ... you must change the configuration accordingly. Edit the following line(s)in /usr/share/openacs/etc/config.tcl:

# The hostname and address should be set to actual values.
# setting the address to 0.0.0.0 means aolserver listens on all interfaces
set hostname localhost
set address 0.0.0.0

After a restart, it should be fine then.

p.s. I won't be able to respond through saturday, in case sth. is unclear, as I am leaving for a hiking trip.

Hallo Stefan,

Vielen Dank für die Hilfe ! Mein Deutsch ist schrecklich so es wird besser auf Englisch sein...

So, I followed your advice. However, I did not find any file "config.tcl" in the folder "/usr/share/openacs/etc" but there was a file named "config.tcl.dpkg-new". I made a copy with a new name ("config.tcl") and I modified and saved it with nano and then, still as root, I typed /etc/init.d/aolserver4 restart. I had the following answer :

gilmar@dotlrn:~$ /etc/init.d/aolserver4 restart
* Stopping web server aolserver4 [ OK ]
* Starting web server aolserver4 [12/Jun/2009:14:59:16][3026.3083183792][-main-] Error: prebind: invalid entry: 127.0.0.1:80: Permission denied [ OK ]

From outside, I tried then http://92.243.19.47/ but no connexion. I connected again with Putty (an ssh utility) and, as the aolserver4 was not running (I saw it with the command ps aux), I typed "/etc/init.d/aolserver4 start".

And then, there was this :

root@dotlrn:/home/gilmar# ps ax | grep nsd
2176 ? Ssl 0:00 /usr/sbin/aolserver4-nsd -u www-data -g www-data -b 127.0.0.1:80 -s main -t /etc/aolserver4/aolserver4.tcl
2273 pts/0 S+ 0:00 grep nsd

And no connexion from outside...

In the folder /etc/aolserver2, there is a file named aolserver4.tcl and it has also a section specifying ports and so on. It says this :

#
# GLOBAL VARIABLES
#

set httpport 80
set httpsport 443
set controlport 9999

set hostname localhost
set address 127.0.0.1

Do I have to change this and replace 127.0.0.1 with 0.0.0.0?

What do you think ?

Thank for your patience (it is a long message, sorry...)

Gilmar

Gilmar,

Sorry, I misguided you, i was confusing the setup variants. The responsible config.tcl in the ubuntu setup is found in:

/etc/openacs/config.tcl

You can learn this also from:

9119 ? Ssl 0:00 /usr/sbin/aolserver4-nsd -u www-data -g www-data -b 127.0.0.1:8000 -t /etc/openacs/config.tcl

You don't have to touch anything related to the aolserver4 package (e.g., /etc/aolserver4/*). This is a bare aolserver installation which is activated by default when installing this package. It is entirely unrelated to the openacs package.
