我正在使用Redis的Sentinel模式。我正在使用Redisson客户端版本3.9.1

使用Redisson配置Sentinel:
@EnableCaching
public class RedisCache {
@Autowired
private ObjectMapper objectMapper;
@Bean
public RedissonClient redissonClient() {
Config config = new Config();
config.setCodec(new JsonJacksonCodec(objectMapper));
config.useSentinelServers()
.setMasterName("redis-master")
.addSentinelAddress("redis://localhost:26378")
.addSentinelAddress("redis://localhost:26379");
return Redisson.create(config);
}
@Bean
public RedissonConnectionFactory redissonConnectionFactory(RedissonClient redisson) {
return new RedissonConnectionFactory(redisson);
}
}

我正在运行两个sentinel服务器和一个没有从站的Redis主服务器。这只是我本地环境的一个设置。
一些命令的输出:
redis-cli -p 26379
127.0.0.1:26379> SENTINEL get-master-addr-by-name redis-master
1) "127.0.0.1"
2) "6379"
redis-cli -p 26378
127.0.0.1:26378> SENTINEL get-master-addr-by-name redis-master
1) "127.0.0.1"
2) "6379"

每当我运行Sping Boot 应用程序时,都会收到以下错误:

如何解决此错误?
附言:我也试过主从配置,一个sentinel连接到主机,另一个连接到从机,但错误仍然是一样的。我试过sentinel在不同的本地机器上运行不同的私有IP,但错误仍然是一样的。尝试了3个sentinel服务器,没有好处。

Redisson似乎不能使用localhost地址。当我将sentinel节点地址替换为AWS上托管的地址时,它工作得很好。
在我看来,Redisson是一个非常不成熟的客户,可以考虑使用lettuce或jedis。
请参阅在https://github.com/redisson/redisson/issues/1736中提交的错误,该错误不允许它关闭。
我面临的大部分问题是当我使用哨兵模式。集群模式我没有尝试过。工程罚款在单一模式。
此外,他们不迎合github上提交的bug或问题几个月,这是显而易见的,因为他们有一个专业和付费版本,所以你是在你自己。
我不建议使用Redisson。

确保同时运行
redis-server
和redis-sentinal <config>
。完成后,检查sentinal运行在哪个端口。它也可以是5000,在我的情况下。然后将"redis://localhost:5000"
传递给addSentinelAddress

您需要设置
checkSentinelsList = false
设置。
