搭建redis哨兵模式：Redis——sentinel哨兵模式_FlyLikeButterfly的博客-CSDN博客

ip：192.168.1.31；

主：192.168.1.31:6379；从1：192.168.1.31:6380；从2：192.168.1.31:6381：

哨兵1：192.168.1.31:26379；哨兵2：192.168.1.31:26380；哨兵3：192.168.1.31:26381；

测试Demo：

package testJedisSentinel;

import java.util.HashSet;
import java.util.Set;

import org.apache.commons.pool2.impl.GenericObjectPoolConfig;

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisSentinelPool;

/**

 */
public class TestJedisSentinel {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		Set<String> sentinels = new HashSet<>();
		sentinels.add("192.168.1.31:26379");
		sentinels.add("192.168.1.31:26380");
		sentinels.add("192.168.1.31:26381");
		GenericObjectPoolConfig<Jedis> poolConfig = new GenericObjectPoolConfig<>();
		poolConfig.setMaxIdle(100);
		poolConfig.setMaxWaitMillis(10000);
		poolConfig.setTestOnBorrow(true);
		int connectionTimeout = 5000;
		int soTimeout = 5000;
		String password = "654321";
		int database = 0;
		try (JedisSentinelPool jspool = new JedisSentinelPool("mymaster", sentinels, poolConfig, 
				connectionTimeout, soTimeout, password, database)) {
			Jedis jedis = jspool.getResource();
			jedis.mset("a", "AAA", "b", "BBB");
			System.out.println(jedis.get("a"));
			System.out.println(jedis.get("b"));
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

}

结果：
