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 | [root@redis1 ~] # yum install vim wget tree ntp net-tools lsof gcc* -y [root@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 | [root@redis1 ~] # yum install ruby rubygems ruby-devel -y #删除ruby的默认源 [root@redis1 ~] # gem source --remove https://rubygems.org/ https: //rubygems .org/ removed from sources #添加源 [root@redis1 ~] # gem sources -a https://ruby.taobao.org https: //ruby .taobao.org added to sources #安装rails [root@redis1 ~] # gem install rails #安装redis和ruby的接口 [root@redis1 ~] # gem install redis |
四、安装redis
