ruby-enterprise permission-denied error

[Stanislav]

Hi,

Today I'm trying to install the latest ruby-enterprise version - ruby-
enterprise-1.8.6-20080507 . Well, the initial installation goes,
however I have problems when using it along with passenger 1.9.0 .

- I'm using Fedora 9 x86_64.

- ruby-enterprise-1.8.6-20080507 is installed at /opt/ruby-
enterprise-1.8.6-20080507

- These are the configurations for apache:

LoadModule passenger_module /usr/lib64/ruby/gems/1.8/gems/
passenger-1.9.0/ext/apache2/mod_passenger.so
PassengerRoot /usr/lib64/ruby/gems/1.8/gems/passenger-1.9.0
PassengerRuby /opt/ruby-enterprise-1.8.6-20080507
#PassengerRuby /usr/bin/ruby

After reloading/restarting the apache with the option to use /opt/ruby-
enterprise I get this error:

*** Passenger ERROR: Could not start the spawn server: /opt/ruby-
enterprise-1.8.6-20080507: Permission denied (13)

The file/dir permissions are these:
drwxr-xr-x 13 root root 4096 2008-06-10 12:56 opt
drwxr-xr-x 5 root root 4096 2008-06-10 12:48 ruby-
enterprise-1.8.6-20080507

these permissions are just the same as /usr/lib64/ruby... where the
standard ruby is located.

Any ideas how to fix those problems. 10x in advance.

Stanislav

Hi,

Maybe a wild guess: but could it be a apparmor/selinux error?

Yeah this seems very much like an SELinux error. Try turning SELinux
off, or giving /opt/ruby-enterprise-1.8.6-20080507 the right permissions.

Well, selinux is disabled. Very strange problem.

cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted

# SETLOCALDEFS= Check local definition changes
SETLOCALDEFS=0

I also tied this:
[root@xenium opt]# chmod -R 777 ruby-enterprise-1.8.6-20080507

- again the same error:

*** Passenger ERROR: Could not start the spawn server: /opt/ruby-
enterprise-1.8.6-20080507: Permission denied (13)

Shouldn't this be the following instead?

/opt/ruby-enterprise-1.8.6-20080507/bin/ruby

Please check your RailsRuby config option.

Shame on me :)

It was the problem.

Moreover I read the whole FAQ and found that it's not the best choice
to install ruby-enterprise on x86_64 arch. What's a pity :( .

Anyway, 10x about the help.

You can install it on x86_64. You won't get the speed improvements, but
you still get the memory usage reductions.

ruby-enterprise ot 64bit platform?

It'll result in a raw CPU performance loss of anywhere between 0% and
20%, depending on the application and the workload. Whether that's a
problem depends on the specific application and the number of visitors.

Well, I think it's CPU consumming, however it also needs memory :) .
It has about 40k page views a day.
