redis 集群出现的错误

1

 

解决方法：  

不用
Jedis jed =new jedis("192.168.56.101");
jed.set(key,value);
用
Set<HostAndPort> jedisClusterNodes = new HashSet<HostAndPort>();
  //Jedis Cluster will attempt to discover cluster nodes automatically
jedisClusterNodes.add(new HostAndPort("192.168.56.101", 6379));
jedisClusterNodes.add(new HostAndPort("192.168.56.101", 6380));
jedisClusterNodes.add(new HostAndPort("192.168.56.101", 6381));
JedisCluster jc = new JedisCluster(jedisClusterNodes);
jc.set(key,value);

解决方法：   初始化JedisCluster时，设定JedisCluster的maxRedirections 

 

JedisCluster(Set<HostAndPort> jedisClusterNode, int timeout, int maxRedirections) ;
JedisCluster jc = new JedisCluster(jedisClusterNodes,5000,1000);

无法读取 节点信息

解决办法： 用root身份启动各个节点 sudo su

无法存入redis集群

解决办法： 用redis-cli -c -p 6381  方式连接集群
