CentOS更新ruby版本

安装redis启动集群时发现这样的报错，

./redis-trib.rb create 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7001 127.0.0.1:7002

查一些资料大概意思是ruby 和gem 版本太低，安装新版本。

# If you already installed ruby and ruby-devel packages with yum before, remove them first before upgrading Ruby

sudo yum remove ruby ruby-devel

# Build and install the latest Ruby from the source as follows

sudo yum groupinstall "Development Tools"
sudo yum install openssl-devel
wget http://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.2.tar.gz
tar xvfvz ruby-2.1.2.tar.gz
cd ruby-2.1.2
./configure
make
sudo make install
