1: (Error: can't read "address": no such variable) after Install OpenACS with NaviServer from Scratch

Posted by Kenneth Wyrick on 08/25/16 11:24 PM

Congratulations, you have installed OpenACS with NaviServer on your machine.
You might start the server manually with

sudo /usr/local/ns/bin/nsd -t /usr/local/ns/config-oacs-5-9.tcl -u nsadmin -g nsadmin

or you can manage your installation with upstart (Ubuntu/Debian). In this case, you might use the following commands

status oacs-5-9
start oacs-5-9
stop oacs-5-9

To use OpenACS, point your browser to http://localhost:8000/
The configuration file is /usr/local/ns/config-oacs-5-9.tcl
and might be tailored to your needs. The access.log and error.log of this instance are in /var/www/oacs-5-9/log
---------------------------------------------
I changed the 127.0.0.1 to 0.0.0.0 tried it and it did not work then to the specific ip address and i still get the following:

kmw@lrn-ubuntu-16-0-4:/var/www/oacs-5-9/log$ sudo /usr/local/ns/bin/nsd -t /usr/local/ns/config-oacs-5-9.tcl -u nsadmin -g nsadmin -b (used the ip address:8000)

what am i not doing?

should it work after editing the ip address in the /usr/local/ns/config-oacs-5-9.tcl ?
or are there other files that need to be edited?

Hi Kenneth,

It looks like you hit a small glitch with Naviserver 4.99.11 release that is corrected for the next (now recent) release (naviserver-4.99.12).

What version of Naviserver are you using?

3: Re: (Error: can't read "address": no such variable) after Install OpenACS with NaviServer from Scratch (response to 2)

Posted by Antonio Pisano on 08/26/16 10:12 AM

Yep, looks like so, the fix is super easy, is really just a missing var in the conf, but as the new version is out there I'd say Kenneth could just upgrade his Naviserver

Posted by Kenneth Wyrick on 08/26/16 04:36 PM

ok i've downloaded https://sourceforge.net/projects/naviserver/files/latest/download?source=files
and what do i need to do to update it? I've done several searches everything comes up with upgrade.

how is it that the script does not pull in the new version?
thank you for helping me. i need to install .lrn several times

Posted by Gustaf Neumann on 08/26/16 05:31 PM

you are probably referring to the install-ns.sh file. This install script "knows" the version numbers from the configuration section at the begin of the script [1]. change the version number of naviserver and the modules from 4.99.11 to 4.99.12 in your downloaded version of the script, and the will get that newest version. i am currently at vacation in greece and can't update the installation script.

-gn
PS: don't run scripts on your machine without looking first, what these are doing.

6: Re: Installing NaviServer-4.99.11 from bitbucket.org (response to 1)

Posted by Kenneth Wyrick on 08/26/16 09:36 PM

ok to install the newer version of naviserver I worked through the instructions at: https://bitbucket.org/naviserver/naviserver/
which instructed me to run:
sudo gunzip < naviserver-4.99.12.tar.gz | tar xvf -

It returned MANY lines i.e. the following:
tar: naviserver-4.99.11/doc/html/naviserver/files/ns_write.html: Cannot open: No such file or directory
naviserver-4.99.11/doc/html/naviserver/files/ns_writecontent.html
tar: naviserver-4.99.11: Cannot mkdir: Permission denied

so now i am trying to figure out how to un-install naviserver-4.99.11. any direction would be greatly appreciated.

thanks.

can i change naviserver version from 11 to 10 on line 210 of the:
https://github.com/gustafn/install-ns/blob/master/install-ns.sh#L210
?
210 version_ns=${version_ns}

Posted by Kenneth Wyrick on 08/26/16 10:29 PM

correction not line 210 but on
line 29 version_ns=4.99.11
change line 29 to version ns=4.99.12

Almost.

$ grep -n 4.99.11 install-ns.sh
29:version_ns=4.99.11
31:version_modules=4.99.11

Lines 29 and 31 should be changed to same: 4.99.12

For clarity, you replaced with "0.0.0.0" not "0.0.0." right?

I have recently upgraded from 4.99.11 to 4.99.12 as you are doing without encountering issues. I run current Debian testing. What kind of distro/version are you running?

What I did was just:
- donwload again install-ns.sh from here to ensure I didn't miss any recent change in the script https://raw.githubusercontent.com/gustafn/install-ns/master/install-ns.sh
- made it executable using chmod
- opened the script looking for any line about naviserver version 4.99.11 and changed it to 4.99.12 (lines about version are at the beginning of the script)
- run the script

My dev istance could run ok without any fiddling, just changing the web server underneath.

Maybe you just need to "clear the room" a bit

i'm using ubuntu 16.0.4.4 server which install postgresql 9.5. I did edit the install-ns.sh and it seem to work but the nsd loaded before the postgres which i think, postgres needs to load before the nsd.

i like that you did it with debian testing. i prefer to use the https://www.turnkeylinux.org/postgresql but ran into compression file setting problems.

Posted by Benjamin Brink on 08/27/16 06:18 PM

Looks like an nsd or other service is already using the port:

"Error: nssock_v4: failed to listen on [0.0.0.0]:8000: Address already in use"

The script sets up an autostart. You can check and control by issuing one of these from root (or sudo):

oacs-5-9 status
oacs-5-9 stop
oacs-5-9 start

It worked using debian testing netinstall. it actually may have been working before but when i ctrl c out of the terminal it stopped the naviserver from running. so now on to using systemctl to start it as a service... next i need to figure out what the it is so i can run the command.

thank you all for your help and support with me working through this install. it really does mean a lot to me.

cheers!

Hi Kenneth,

FYI, if you run nsd from the terminal, it's normal for it to quit with ctrl-c.

Since you've already installed on ubuntu using the install-ns.sh script, you should be able to control starting, stopping the server with:

sudo status oacs-5-9
sudo start oacs-5-9
sudo stop oacs-5-9

There should be no need to do something else.
cheers,
Ben

22: steps to install oacs/lrn (response to 1)

Posted by Kenneth Wyrick on 08/28/16 02:27 AM

1. Installed debian testing netinstall

2. apt-get install postgres

3. cd /usr/local/src/

4. download the two install scripts:
https://raw.githubusercontent.com/gustafn/install-ns/master/install-ns.sh
https://raw.githubusercontent.com/gustafn/install-ns/master/install-oacs.sh

5. edit the install-ns.sh under settings: #ns_install_dir=/usr/local/oo2
version_ns=4.99.12
#version_ns=HEAD
version_modules=4.99.12
*changed from 4.99.11 to 4.99.12
