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。
0x00 主机环境如下
[root@test ~]# cat /etc/redhat-release
CentOS release 6.7 (Final) [root@test ~]# uname -r 2.6.32-573.el6.x86_64
0x01 使用yum安装ruby
[root@web ~]# yum install rubygems ruby-devel
0x02 查看ruby的版本
[root@web ~]# ruby -v ruby 1.8.7 (2013-06-27 patchlevel 374) [x86_64-linux]
0x03 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: key 39499BDB: public key "Piotr Kuczynski <piotr.kuczynski@gmail.com>" imported gpg: no ultimately trusted keys found gpg: Total number processed: 2 gpg: imported: 1 (RSA: 1) gpg: unchanged: 1
b:接着执行如下命令：
[root@web ~]# curl -sSL https://get.rvm.io | bash -s stable

curl: (35) SSL connect error

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
