Jedis叢集測試_李孟_新浪部落格

//建立叢集節點集合

  Set nodes=new HashSet<>();

  nodes.add(new HostAndPort("192.168.193.129", 7001));

  nodes.add(new HostAndPort("192.168.193.129", 7002));

  nodes.add(new HostAndPort("192.168.193.129", 7003));

  nodes.add(new HostAndPort("192.168.193.129", 7004));

  nodes.add(new HostAndPort("192.168.193.129", 7005));

  nodes.add(new HostAndPort("192.168.193.129", 7006));

  //建立叢集對象

  JedisCluster cluster=new JedisCluster(nodes);

  cluster.set("cluster1", "Hello  World!");

  System.out.println(cluster.get("cluster1"));

  cluster.close();

環境:redis.3.0+CentOS-6.4

運作上述程式後報錯:redis.clients.jedis.exceptions.JedisClusterMaxRedirectionsException: Too many Cluster redirections?(大概意思是 連接配接數太多重定向了嗎？！)

解決方案：

第一種：在建立cluster的時候，帶上逾時時間和最大重定向數。

JedisCluster cluster=new JedisCluster(nodes,3000,1000);

第二種：檢視 cluster nodes 資訊

get cluster1

-> Redirected to slot [8483] located at 127.0.0.1:7002

"Hello  World!"

連接配接逾時，配置叢集詳細ip
