[LON-CAPA-admin] Install error

The whole install command thing has fixed all of my errors. I no longer have to worry about changing the permissions of the extracted tarball, and received no errors about missing directories. I emailed our unix team about the package that adds the additional install command and they responded that they use it to maintain the systems. However, I just changed my path to ensure it uses the correct one.  Sorry for all of the troubles.

I have a couple other questions though. I am just installing a machine for internal testing now. I am assuming I should choose stand-alone as the cluster option. Once I do that, does the domain name I use matter? Should I use the purdue domain that is in use in production or create a new one? I would like to clone the data from our production machine to this if possible after the installation.


Thanks,
Richard

Stuart,

Thanks for letting me know you didn't expect the files be moved. This helped me trace down the issue since they were being moved on my system. I found that there was a different install command that was running out of /usr/local/bin instead of the default one in /usr/bin and that one was first in my path. The one in /usr/local/bin was apparently provided by the install_base package. I will reinstall tomorrow using the correct install command. Unfortunately we do not do the Linux installs, there is a separate team that does that and they use a prebuilt image to do the builds. 

It also includes certain groups and such. The admin group is the group for the unix admins. However that should not be a problem since the install.pl script just uses useradd to add the www user and it would never get gid 500 except by chance. 

Richard

The line immediately before the step to run the "commands" script to unzip the fonts file is:

install -p -o www -g www -m 0644 ../../loncom/html/adm/jsMath/*.* /home/httpd/html/adm/jsMath/.

which should copy all files matching *.* from loncom/html/adm/jsMath/ to /home/httpd/html/adm/jsMath/

The files are not moved (i.e., they should all still be there in loncom/html/adm/jsMath/), so the command "cannot find or open jsMath-fonts-1.3.zip" suggests that the change directory command immediately prior to attempting to run the commands script failed, such that unzip is running in the wrong directory context.

You are running ./UPDATE as root, correct?

I would note that LON-CAPA installation process will create all required directories and sub-directories for you, so there should be never be a need to create them manually.

It is possible that all the issues you have encountered originate from the initial error you reported on 5/1:

>         "/bin/bash" > Makefile.build
> install -d ../../doc/man
> install: destination owner 500 doesn't exist
> make: *** [build] Error 67
> **** ERROR **** command "make build" failed

such that ownership/permissions were preventing make build from creating the directories and sub-directories needed later in the installation process.

Apparently, you already had a group (admin) with a GID of 500, whereas the UID and GID of 500 are usually assigned to the www user/group which are created by install.pl (which is run to prepare a Linux server/VM for installation of LON-CAPA).

The LON-CAPA installation instructions (e.g., http://install.loncapa.org/RHEL6_install.html for Red Hat 6) suggest a minimal Red Hat Enterprise Linux 6 Install as the starting point, which in my experience, does not create an "admin" group.

Could you send an e-mail to helpdesk at loncapa.org and, as attachments, include the Makefile.build and Mekfile.install files created when you ran ./UPDATE

If you downloaded the LON-CAPA tarball to <some directory path> you will find those files in: <some directory  
path>/loncapa-2.10.1/loncom/build

-- where <some directory path> is the place where you downloaded (and
extracted) the loncapa-2.10.1.tar.gz tarball.

One other suggestion I have would be to run:
make reallyclean

from within "<some directory path>/loncapa-2.10.1/loncom/build" to remove all files generated during earlier build attempts, and then to start over again by running ./UPDATE (as root).
