Install Ruby Version Manager (RVM) On CentOS 5.5(转)

 

RVM, or Ruby Version Manager is a popular and effective way to manage running multiple Ruby environments. Here is how you set it up on CentOS 5.5:

1) Add the Webtatic respository and install Git.

1 2	rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm yum install --enablerepo=webtatic git

(Note that this command will also install the perl-Error and perl-Git dependencies)

2) Create an rvm user and group.

1 2	groupadd rvm useradd -g rvm rvm

3) Add the root user to the rvm group (required for installation)

1	usermod -a -G rvm root

4) Install RVM as root.
