redis cluster

1.建立目录
/opt/redis/redis-cluster
/opt/redis/redis-cluster/redis_node_7379/conf/
/opt/redis/redis-cluster/redis_node_7379/rdb/
/opt/redis/redis-cluster/redis_node_7380/conf/
/opt/redis/redis-cluster/redis_node_7380/rdb/
/opt/redis/redis-cluster/redis_node_7381/conf/
/opt/redis/redis-cluster/redis_node_7381/rdb/
/opt/redis/redis-cluster/redis_node_7382/conf/
/opt/redis/redis-cluster/redis_node_7382/rdb/
/opt/redis/redis-cluster/redis_node_7383/conf/
/opt/redis/redis-cluster/redis_node_7383/rdb/
/opt/redis/redis-cluster/redis_node_7384/conf/
/opt/redis/redis-cluster/redis_node_7384/rdb/

说明:7379、7380、7381、7382、7383、7384，为集群每个节点的端口

2、redis.conf配置
修改redis.conf配置，以节点7379为例，修改以下项:

daemonize yes #守护进程
port 7379 #每个节点的端口
dir /opt/redis/redis-cluster/redis_node_7379/rdb/ #指定数据文件位置
cluster-enabled yes #启用集群模式
cluster-config-file /opt/redis/redis-cluster/redis_node_7379/conf/node_7379.conf #节点的配置文件,集群启动后自动产生
cluster-node-timeout 1500 #节点访问超时时间为1500毫秒
注释bind 127.0.0.1 #去掉bind绑定访问ip信息
protected-mode no #关闭保护模式

说明：不同的节点，配置文件端口改成节点对应的端口

3、分别启动节点
redis-server /opt/redis/redis-cluster/redis_node_7379/conf/redis.conf
redis-server /opt/redis/redis-cluster/redis_node_7380/conf/redis.conf
redis-server /opt/redis/redis-cluster/redis_node_7381/conf/redis.conf
redis-server /opt/redis/redis-cluster/redis_node_7382/conf/redis.conf
redis-server /opt/redis/redis-cluster/redis_node_7383/conf/redis.conf
redis-server /opt/redis/redis-cluster/redis_node_7384/conf/redis.conf

4、检查进程启动情况

5、构建redis集群
redis-cli [-a xxx] --cluster create --cluster-replicas 1 192.168.0.143:7379 192.168.0.143:7380 192.168.0.143:7381 192.168.0.143:7382 192.168.0.143:7383 192.168.0.143:7384

说明:
(1)redis3时使用的是redis-trib.rb （ruby脚本构建集群）
(2)-a xxx 密码，如果设置了密码的话
