spring搭建redis集群

在我的虚拟机上安装了三台linux red hat6

版本redis3.0.6

192.168.1.81 redis 的master

192.168.1.82 slave

192.168.1.83 slave

注意配置ip和防火墙的关闭

81上redis的配置

port 6379

82,83上redis的配置

port 6379
slaveof 192.168.1.81 6379

从服务器上就多了个主的配置

sentinel的配置基本是默认的

下面使用spring-data-redis来配置集群

<bean id="jeidsConnectionFactory"

</bean>

<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
<property name="connectionFactory" ref="jeidsConnectionFactory" />
<property name="keySerializer">

<property name="valueSerializer">

<property name="hashKeySerializer">

</property>
<property name="hashValueSerializer">
<bean
class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
</property>
</bean>
</beans>

再看看maven pom.xml的配置

<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>1.6.0.RELEASE</version>
</dependency>
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.8.0</version>
</dependency>

在java中使用缓存

@Autowired
private RedisTemplate redisTemplate;
///////////////////////////////////////
ValueOperations<String, Object> valueOper=redisTemplate.opsForValue();
valueOper.set(key,value);

测试下主从切换

我把master关闭之后，自动切换到83上面

3209:X 19 Jan 12:55:17.432 # +sdown slave 192.168.1.81:6379 192.168.1.81 6379 @ mymaster 192.168.1.83 6379

运行redis-cli

keys *

可以看到ok了
