Question

I trying to deploy rails app in CentOS 6.3 for 3 days, and I had no success until now.
I want to use rbenv, but I am getting these errors:

I created a new user ‘deployer’ and installed rbenv using it. Logout and Login again.
When I log in, I get this error:

-bash: /home/deployer/.rbenv/bin/rbenv: Permission denied

If I install rbenv using root user, It loads rbenv after install, but the error is when I try install ruby:

$ rbenv install 1.9.3-p125

EDIT

Permissions of rbenv installed by deployer:

drwxr-xr-x.  8 deployer  deployer  4096 Dec 14 13:11 .rbenv

Answer 1

I was getting this error because folder was mounted with noexec option.
