一、环境
系统    CentOS7.0 64位最小化安装
redis1    172.16.1.46    6379,6380
redis2    172.16.1.47    6379,6380
redis3    172.16.1.47    6379,6380
二、基础软件安装

1 2	[iyunv@redis1 ~]# yum install vim wget tree ntp net-tools lsof gcc* -y [iyunv@redis1 ~]# yum -y install gcc openssl-devel libyaml-devel libffi-devel readline-devel zlib-devel gdbm-devel ncurses-devel gcc-c++ automake autoconf libxml2* rubygem-nokogiri

三、安装ruby

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

[iyunv@redis1 ~]# yum install ruby rubygems ruby-devel -y #删除ruby的默认源 [iyunv@redis1 ~]# gem source --remove https://rubygems.org/ https://rubygems.org/ removed from sources #添加源 [iyunv@redis1 ~]# gem sources -a https://ruby.taobao.org https://ruby.taobao.org added to sources #安装rails [iyunv@redis1 ~]# gem install rails #安装redis和ruby的接口 [iyunv@redis1 ~]# gem install redis

四、安装redis
