搭建redis集群

  • 最少6台机器，分别在其中六台机器也部署一套redis

创建集群

  • 找一台机器做master控制集群节点，或者也可以在redis集群中其中一台安装master节点
yum -y install ruby ruby-devel rubygems rpm-build
rvm -v
gem install redis
yum install -y rubygems
redis-cli --cluster create 192.168.13.1:6301 192.168.13.2:6302 192.168.13.3:6303 192.168.13.4:6304 192.168.13.5:6305 192.168.13.6:6306 --cluster-replicas 1
