[英]How to configure ElastiCache Redis for Spring Data Access
I am trying to setup ElastiCache to use with a Java Application.我正在尝试设置 ElastiCache 以与 Java 应用程序一起使用。 I have based my setup based on this documentation: https://docs.aws.amazon.com/AmazonElastiCache/latest/UserGuide/BestPractices.html
我的设置基于此文档: https : //docs.aws.amazon.com/AmazonElastiCache/latest/UserGuide/BestPractices.html
The EC2 instance where the Java (8) App runs is in a VPC. Java (8) 应用程序运行所在的 EC2 实例位于 VPC 中。 I have tried an ElastiCache instance both in VPC and no VPC.
我在 VPC 和非 VPC 中都尝试过 ElastiCache 实例。 However, I always got,
然而,我总是得到,
redis.clients.jedis.exceptions.JedisConnectionException: java.net.ConnectException: Connection refused
If I install Redis myself on an EC2 instance and connect to it, the app is able to connect to the Redis Cache!如果我自己在 EC2 实例上安装 Redis 并连接到它,应用程序就能够连接到 Redis 缓存!
I have setup proper authorization with Security-group from EC2 to Cache-Security but no luck.我已经设置了从 EC2 到缓存安全的安全组的正确授权,但没有运气。 I just can't make the 'connection'.
我只是无法建立“连接”。 Any sample connection snippet would be really helpful.
任何示例连接片段都会非常有帮助。
Redis is setup this way in the APP Config: Redis 在 APP Config 中是这样设置的:
@Bean
public JedisConnectionFactory redisConnectionFactory() {
JedisConnectionFactory redisConnectionFactory = new JedisConnectionFactory();
redisConnectionFactory.setHostName(<cache-node>);
redisConnectionFactory.setPort(6397);
redisConnectionFactory.setUsePool(true);
redisConnectionFactory.setTimeout(3600);
return redisConnectionFactory;
}
The various versions:各种版本:
Jedis- 2.6.2, Spring- 4.1.6, Spring-data-> 1.5.0
telnet redis-ip 6397
判断redis是否可以连接
redisConnectionFactory.setPort(6397);
应该是
redisConnectionFactory.setPort(6379); //default redis port
