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：
[root@test ~]# cat /etc/redhat-release
CentOS release 6.7 (Final)
[root@test ~]# uname -r
2.6.-.el6.x86_64
2、使用yum安装ruby
[root@web ~]# yum install rubygems ruby-devel
Loaded plugins: fastestmirror, security

3、查看ruby的版本
[root@web ~]# ruby -v
ruby 1.8. (-- patchlevel ) [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 http://rubygems.org/
2）添加aliyun的rubygems仓库
[root@web ~]# gem sources -a http://mirrors.aliyun.com/rubygems/
3）查看rubygems仓库
[root@web ~]# gem sources -l
*** CURRENT SOURCES *** http://mirrors.aliyun.com/rubygems/
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：
[root@web ~]# gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
gpg: requesting key D39DC0E3 from hkp server keys.gnupg.net
gpg: requesting key 39499BDB from hkp server keys.gnupg.net
gpg: key D39DC0E3: "Michal Papis (RVM signing) <mpapis@gmail.com>" not changed

gpg: no ultimately trusted keys found
gpg: Total number processed:

gpg: unchanged:
b:接着执行如下命令：
[root@web ~]# \curl -sSL https://get.rvm.io | bash -s stable
Downloading https://github.com/rvm/rvm/archive/1.29.3.tar.gz
curl: () SSL connect error Could not download 'https://github.com/rvm/rvm/archive/1.29.3.tar.gz'.

curl returned status ''. Creating group 'rvm' Installing RVM to /usr/local/rvm/
Installation of RVM in /usr/local/rvm/ is almost complete: * First you need to add all users that will be using rvm to 'rvm' group,
and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`. * To start using RVM you need to run `source /etc/profile.d/rvm.sh`
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
5、查看RVM可安装的ruby的版本
[root@web ~]# rvm list known

6、安装ruby-1.9.3版本
[root@web ~]# rvm install 1.9.
Searching for binary rubies, this might take some time.
