Build a ruby on rails development environment under CentOS7, centos7rails

1. Install rvm

Curl-L https://get.rvm.io | bash-s stable

Rvm is a command line tool that provides management and switching of Multi-version ruby environments. You can also manage different gemsets based on projects.

If the ssh key is not generated, this step may fail. directly generate the key using ssh-keygen and then install the key.

Gpg problems may also occur: Execute as prompted:

Gpg2 -- keyserver hkp: // keys.gnupg.net -- recv-keys 409b6b1796c275462a1703111084bb82d39dc0e3

. If it fails, run: command curl-sSL https://rvm.io/mpapis.asc | gpg2 -- import -. Install rvm again and perform some operations as prompted. Then rvm-v can see that rvm is installed.

If the installation fails, try to connect to the vpn before installing.

2. Use rvm to install the ruby version you need

Rvm install 2.1.1

Here I installed ruby 2.1.1.
