升级ruby版本，有时候安装ruby的版本过低，需要进行升级，例如安装在centos6.7安装fpm需要ruby版本在1.9以上。
1、主机环境如下：
1 [root@test ~]# cat /etc/redhat-release
2 CentOS release 6.7 (Final)
3 [root@test ~]# uname -r
4 2.6.32-573.el6.x86_64
2、使用yum安装ruby
1 [root@web ~]# yum install rubygems ruby-devel
2 Loaded plugins: fastestmirror, security

3、查看ruby的版本
1 [root@web ~]# ruby -v
2 ruby 1.8.7 (2013-06-27 patchlevel 374) [x86_64-linux]
4、升级ruby1.9.3版本
1）删除原来的rubygems仓库
[root@web ~]# gem sources --remove https://rubygems.org/
2）添加aliyun的rubygems仓库
[root@web ~]# gem sources -a https://gems.ruby-china.com/
3）查看rubygems仓库
1 [root@web ~]# gem sources -l
2 *** CURRENT SOURCES ***
3
4 https://gems.ruby-china.com/
4）使用RVM进行升级ruby
a:在rvm官方网址：https://rvm.io/执行如下命令：
1 [root@web ~]# gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
2 gpg: requesting key D39DC0E3 from hkp server keys.gnupg.net
3 gpg: requesting key 39499BDB from hkp server keys.gnupg.net

17 Installing RVM to /usr/local/rvm/
18 Installation of RVM in /usr/local/rvm/ is almost complete:
19
20 * First you need to add all users that will be using rvm to 'rvm' group,
21 and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.
22
23 * To start using RVM you need to run `source /etc/profile.d/rvm.sh`
24 in all your open shell windows, in rare cases you need to reopen all shell windows.
c:执行上述命令 * To start using RVM you need to run `source /etc/profile.d/rvm.sh`
[root@web ~]# source /etc/profile.d/rvm.sh
