Question

我正在使用Redis的Sentinel模式。我正在使用Redisson Client 3.9.1

<dependencies>
    <dependency>
        <groupId>org.redisson</groupId>
        <artifactId>redisson-spring-data-20</artifactId>
        <version>${redisson-version}</version>
    </dependency>
    <dependency>
        <groupId>org.redisson</groupId>
        <artifactId>redisson</artifactId>
        <version>${redisson-version}</version>
    </dependency>
</dependencies>

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);
    }
}

我正在运行两台哨兵服务器和一台Redis主服务器，没有从属服务器。这只是我本地环境中的设置。
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Spring Boot应用程序时，都会出现以下错误：

       Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'redissonClient' defined in class path resource [xxxx/cache/impl/redis/config/RedisCache.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.redisson.api.RedissonClient]: Factory method 'redissonClient' threw exception; nested exception is org.redisson.client.RedisConnectionException: At least two sentinels should be defined in Redis configuration!

如何解决此错误？

PS：我也尝试了主从配置，其中一个哨兵连接到主机，另一个哨兵连接到从属，但是错误仍然相同。我尝试过在具有不同私有IP的不同本地计算机上运行的哨兵，但错误仍然相同。尝试使用3个哨兵服务器，没有任何好处。

Answer 1

确保同时运行 redis-server 和 redis-sentinal <config>。完成后，检查哨兵正在运行的端口。它也可能是 5000，就我而言。然后将 "redis://localhost:5000" 传递给 addSentinelAddress。

Answer 2

Redisson似乎不适用于本地主机地址。当我用AWS托管的地址替换前哨节点地址时，它工作正常。

在我看来，Redisson是一位非常不成熟的客户。考虑使用生菜或吉迪斯。

查看在https://github.com/redisson/redisson/issues/1736处提交的错误不允许它关闭。

我遇到的大多数问题是使用哨兵模式时。我没有尝试过集群模式。在单模式下可以正常工作。

此外，他们几个月都无法满足在github上提交的错误或问题，这很明显，因为它们具有专业版和付费版本，因此您是一个人。

到目前为止，我不建议使用Redisson。

Answer 3

Redisson与本地主机地址完美配合。在您的情况下，SENTINEL SENTINELS命令返回空结果。这意味着Redis安装程序配置不正确。

Spring Redisson Sentinel错误-至少需要两个哨兵
