23rfe

                      

系统环境：CentOS release 6.7_x86_64

软件环境:redis-3.0.5

1、yum install ruby rubygems  #安装ruby环境依赖
2、gem install redis #安装redis集群管理器

1 2 3 4

Successfully installed redis-3.2.2 1 gem installed Installing ri documentation for redis-3.2.2... Installing RDoc documentation for redis-3.2.2...

3、cp redis源码包/src/redis-trib.rb /usr/local/bin/redis-trib
4、在配置文件中添加

cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000

5、启动服务
6、ps -aux | grep redis #查看服务是否是以集群方式启动

注：redis集群必须要有3个主节点
1、创建集群

1	[iyunv@localhost /]# redis-trib create --replicas 1 192.168.2.105:6379 192.168.2.105:6380 192.168.2.105:6381 192.168.2.105:6382 192.168.2.105:6383 192.168.2.105:6384

  2、redis-cli -c -h 192.168.2.105 -p 6382 #进入节点

  3、192.168.2.105:6383> cluster info #查看集群的状态

1 2 3 4 5 6 7 8 9 10 11

cluster_state:ok cluster_slots_assigned:16384 cluster_slots_ok:16384 cluster_slots_pfail:0 cluster_slots_fail:0 cluster_known_nodes:6 cluster_size:3 cluster_current_epoch:6 cluster_my_epoch:1 cluster_stats_messages_sent:353048 cluster_stats_messages_received:353048

  4、192.168.2.105:6383> cluster nodes #查看各节点的状态
