Install gem and redis plugin

Plugin download address: https://rubygems.global.ssl.fastly.net/gems/redis-3.2.1.gem
Then execute:

gem install -l ./redis-3.2.1.gem

I was very tired. I just started the yum installation and found that the ruby ​​version was too low to download the plug-in, which made me delete all the yum installations of ruby ​​and gem. All source code installed, using the latest version.

yum uninstall command

yum -y remove [ruby] #yum安装的应用程序名

The redis high-availability cluster is also completed, and a wave of clusters will be operated with jedis tomorrow.
