Unknown error when installing Ruby Stack

I tried to install Ruby Stack on Ubuntu and I got the following error after 100% of the installation was reached:
########################################
Error: Unknown error while running
/opt/rubystack-2.0-3/mysql/scripts/myscript.sh /opt/rubystack-2.0-3/mysql

After fixing mysql/scripts/myscript.sh (one of the lines had relative path) I’m still getting this:

root@projects:/opt/rubystack# ./ctlscript.sh restart
Syntax OK
/opt/rubystack/apache2/scripts/ctl.sh : apache not running
/opt/rubystack/memcached/scripts/ctl.sh : Memcached stopped
/opt/rubystack/memcached/scripts/ctl.sh : Memcached started
/opt/rubystack/mysql/scripts/ctl.sh : mysql not running
100504 05:00:47 mysqld_safe Logging to ‘/opt/rubystack/mysql/data/mysqld.log’.
chown: invalid user: `mysql’

Why ‘mysql’ user is not found?

Have you installed the stack as root user? Try to create the mysql user if it does not already exist:

/usr/sbin/useradd mysql

I was able to finish the installation by editing and re-running /opt/rubystack/mysql/scripts/myscript.sh:
Just add line “cd /opt/rubystack/mysql” before and after mysql_install_db command in that file, it looks like the current directory is not properly preserved.

Actually RubyStack is non functional as I can’t install any modules on top of it. How can I verify the installation?

To beltran: yes, I’m the root user.

It is possible that the properties.ini file has not been created because of the error during the installation. Is it possible that you have SELinux enabled? Could y ou disable it before running the Stack installer?

I traced it to the low memory issue. All works fine after I added memory and reinstalled.

I’m glad to hear this!
