Redis集群错误：Caused by: redis.clients.jedis.exceptions.JedisNoReachableClusterNodeException: No reachable node in cluster

使用spring-data-redis练习连接redis集群时出现以下错误信息

Exception in thread "main" org.springframework.data.redis.RedisConnectionFailureException: No reachable node in cluster; nested exception is redis.clients.jedis.exceptions.JedisNoReachableClusterNodeException: No reachable node in cluster at org.springframework.data.redis.connection.jedis.JedisExceptionConverter.convert(JedisExceptionConverter.java:65) at org.springframework.data.redis.connection.jedis.JedisExceptionConverter.convert(JedisExceptionConverter.java:42) at org.springframework.data.redis.PassThroughExceptionTranslationStrategy.translate(PassThroughExceptionTranslationStrategy.java:44) at org.springframework.data.redis.FallbackExceptionTranslationStrategy.translate(FallbackExceptionTranslationStrategy.java:42) at org.springframework.data.redis.connection.jedis.JedisClusterConnection.convertJedisAccessException(JedisClusterConnection.java:777) at org.springframework.data.redis.connection.jedis.JedisClusterStringCommands.convertJedisAccessException(JedisClusterStringCommands.java:525) at org.springframework.data.redis.connection.jedis.JedisClusterStringCommands.set(JedisClusterStringCommands.java:118) at org.springframework.data.redis.connection.DefaultedRedisConnection.set(DefaultedRedisConnection.java:281) at org.springframework.data.redis.core.DefaultValueOperations$3.inRedis(DefaultValueOperations.java:240) at org.springframework.data.redis.core.AbstractOperations$ValueDeserializingRedisCallback.doInRedis(AbstractOperations.java:60) at org.springframework.data.redis.core.RedisTemplate.execute(RedisTemplate.java:228) at org.springframework.data.redis.core.RedisTemplate.execute(RedisTemplate.java:188) at org.springframework.data.redis.core.AbstractOperations.execute(AbstractOperations.java:96) at org.springframework.data.redis.core.DefaultValueOperations.set(DefaultValueOperations.java:236) at com.etoak.ClusterTest.main(ClusterTest.java:15) Caused by: redis.clients.jedis.exceptions.JedisNoReachableClusterNodeException: No reachable node in cluster at redis.clients.jedis.JedisSlotBasedConnectionHandler.getConnection(JedisSlotBasedConnectionHandler.java:69) at redis.clients.jedis.JedisSlotBasedConnectionHandler.getConnectionFromSlot(JedisSlotBasedConnectionHandler.java:86) at redis.clients.jedis.JedisClusterCommand.runWithRetries(JedisClusterCommand.java:102) at redis.clients.jedis.JedisClusterCommand.runBinary(JedisClusterCommand.java:49) at redis.clients.jedis.BinaryJedisCluster.set(BinaryJedisCluster.java:105) at org.springframework.data.redis.connection.jedis.JedisClusterStringCommands.set(JedisClusterStringCommands.java:116) ... 8 more

采用的是java 配置文件的方式来配置redis，配置文件如下

import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.connection.RedisClusterConfiguration; import org.springframework.data.redis.connection.RedisNode; import org.springframework.data.redis.connection.jedis.JedisConnectionFactory; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.core.StringRedisTemplate; import redis.clients.jedis.JedisPoolConfig; import java.util.HashSet; import java.util.Set; @Configuration public class ClusterConfig { @Bean public JedisPoolConfig poolConfig(){ JedisPoolConfig poolConfig = new JedisPoolConfig(); poolConfig.setMaxTotal(50); poolConfig.setMaxIdle(50); poolConfig.setMinIdle(1); return poolConfig; } @Bean public RedisClusterConfiguration clusterConfiguration(){ RedisClusterConfiguration config = new RedisClusterConfiguration(); Set<RedisNode> nodes = new HashSet<>(); for(int port = 6001;port <= 6006;port++){ nodes.add(new RedisNode("192.168.60,128",port)); } config.setClusterNodes(nodes); return config; } @Bean public JedisConnectionFactory connectionFactory(){ return new JedisConnectionFactory(this.clusterConfiguration(),this.poolConfig()); } @Bean("stringRedisTemplate") public StringRedisTemplate stringRedisTemplate(){ return new StringRedisTemplate(this.connectionFactory()); } @Bean("redisTemplate") public RedisTemplate redisTemplate(){ RedisTemplate template = new RedisTemplate(); template.setConnectionFactory(this.connectionFactory()); return template; } }

经过排查是在设置RedisClusterConfiguration设置主机是IP地址写错了 把 192.168.60.128 写成了 192.168.60,128。 修改clusterConfiguration()方法后，代码成功运行

@Bean public RedisClusterConfiguration clusterConfiguration(){ RedisClusterConfiguration config = new RedisClusterConfiguration(); Set<RedisNode> nodes = new HashSet<>(); for(int port = 6001;port <= 6006;port++){ nodes.add(new RedisNode("192.168.60.128",port)); } config.setClusterNodes(nodes); return config; }
