redis-cluster 部署的redis集群

1、命令连接redis集群

./src/redis-cli -h 192.168.33.159 -c -p 7001

2、通过java代码 连接redis集群

添加依赖包

<dependency>  
<groupId>redis.clients</groupId>  
<artifactId>jedis</artifactId>

</dependency>

编写测试类

package com.boot.business;  
  
import java.io.IOException;  
import java.util.LinkedHashSet;  
import java.util.Set;  
import redis.clients.jedis.HostAndPort;  
import redis.clients.jedis.JedisCluster;  
import redis.clients.jedis.JedisPoolConfig;  
  
public class AppTest \{  
public static void main(String\[\] args) \{  
JedisPoolConfig poolConfig = new JedisPoolConfig();  
// 最大连接数  
poolConfig.setMaxTotal(1);  
// 最大空闲数  
poolConfig.setMaxIdle(1);  
// 最大允许等待时间，如果超过这个时间还未获取到连接，则会报JedisException异常：  
// Could not get a resource from the pool  
poolConfig.setMaxWaitMillis(1000);  
Set<HostAndPort> nodes = new LinkedHashSet<HostAndPort>();  
nodes.add(new HostAndPort("192.168.33.159", 7001));  
nodes.add(new HostAndPort("192.168.33.159", 7002));  
nodes.add(new HostAndPort("192.168.33.159", 7003));  
nodes.add(new HostAndPort("192.168.33.159", 7004));  
nodes.add(new HostAndPort("192.168.33.159", 7005));  
nodes.add(new HostAndPort("192.168.33.159", 7006));  
JedisCluster cluster = new JedisCluster(nodes, poolConfig);  
String name = cluster.get("name");  
System.out.println(name);  
cluster.set("age", "18");  
System.out.println(cluster.get("age"));  
try \{  
cluster.close();  
\} catch (IOException e) \{  
e.printStackTrace();  
\}  
\}  
\}

运行结果
