Redis集群 之 Cluster模式Windows篇
1.环境：
a.下载Redis：访问 https://github.com/MicrosoftArchive/redis/releases 下载Windows版Redis，并解压
b.安装Ruby：访问 http://dl.bintray.com/oneclick/rubyinstaller/rubyinstaller-2.3.3-x64.exe 下载Windows版Ruby，并安装
c.配置Ruby：在cmd命令行执行 gem install redis。
2.集群配置
a.复制6份Redis作为6个节点，分别命名为8081、8082、8083、8084、8085 和 8086
b.修改 Redis 各节点中的 redis.windows.conf 配置文件
#端口号改为8081，其他5个端口号分别为 8082、8083、8084、8085、8086 port 8081 #开启集群模式 cluster-enabled yes #保存节点配置,自动创建,自动更新(建议命名时加上端口号) cluster-config-file nodes-8081.conf #集群超时时间，节点超过这个时间没反应就断定是宕机 cluster-node-timeout 15000 #指定是否在每次更新操作后进行日志记录，Redis在默认情况下是异步的把数据写入磁盘，如果不开启，可能会在断电时导致一段时间内的数据丢失。 yes表示：存储方式，aof，将写操作记录保存到日志中 appendonly yes
c.在每个节点目录下创建 start.bat 来启动 redis
title redis-8081
redis-server.exe redis.windows.conf
d.下载redis-trib.rb
1）访问 https://github.com/microsoftarchive/redis/releases/tag/win-3.2.100 下载 Source code(zip) 源码包
2）解压源码包将 src 目录下的 redis-trib.rb 文件复制到 redis集群的目录下
e.配置Redis集群
1）双击各节点文件夹下的 start.bat 文件启动各Redis节点
2）到redis集群目录下执行cmd命令：ruby redis-trib.rb create --replicas 1 127.0.0.1:8081 127.0.0.1:8082 127.0.0.1:8083 127.0.0.1:8084 127.0.0.1:8085 127.0.0.1:8086。
3）在出现 Can I set the above configuration? (type 'yes' to accept): 时输入 yes
f.注意：
1）Ruby集群命令只需要执行一次，以后只需要执行各节点的 start.bat 即可
3.测试
a.连接任意一个节点：redis-cli.exe -c -p 8081
b.设置一个键：set name vettel
c.退出Redis控制台：exit
d.再连接另一个节点：redis-cli.exe -c -p 8083
e.获取这个键：get name
4.使用Jedis操作Cluster模式Redis集群
a.导入maven依赖
<dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.10.0</version> </dependency>
b.使用
public class TestCluster { private static JedisCluster jedis; static { init(); } /** * 初始化redis连接池 */ private static void init(){ JedisPoolConfig config = new JedisPoolConfig(); config.setMaxIdle(5); //最大空闲数 config.setMaxWaitMillis(60000); //连接时最大的等待时间（毫秒） config.setMaxTotal(500); //最大连接数 config.setTestOnBorrow(true); //在提取一个jedis实例时，是否提前进行验证操作；如果为true，则得到的jedis实例均是可用的 Set<HostAndPort> nodes = new HashSet<>(); nodes.add(new HostAndPort("127.0.0.1", 8081)); nodes.add(new HostAndPort("127.0.0.1", 8082)); nodes.add(new HostAndPort("127.0.0.1", 8083)); nodes.add(new HostAndPort("127.0.0.1", 8084)); nodes.add(new HostAndPort("127.0.0.1", 8085)); nodes.add(new HostAndPort("127.0.0.1", 8086)); jedis = new JedisCluster(nodes, config); } public static JedisCluster getJedis() { return jedis; } public static void returnJedis(JedisCluster jedis){ if(jedis != null){ try { jedis.close(); } catch (IOException e) { e.printStackTrace(); } } } /** * 测试 * @param args */ public static void main(String[] args) { JedisCluster jedis = TestCluster.getJedis(); jedis.set("name", "zwin"); jedis.set("age", "29"); jedis = TestCluster.getJedis(); String name = jedis.get("name"); String age = jedis.get("age"); System.out.println("name[" + name + "], age[" + age + "]"); //JedisCluster为单例模式，需最后再关闭 returnJedis(jedis); } }
6.Spring操作Cluster模式Redis集群
a.导入Maven依赖
<properties> ..... <!-- spring --> <spring.version>5.1.1.RELEASE</spring.version> <!-- jackson-json --> <jackson.version>2.9.4</jackson.version> <!-- log4j --> <slf4j.version>1.7.18</slf4j.version> <log4j.version>1.2.17</log4j.version> </properties> <dependencies> <!-- spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- Jackson --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>${jackson.version}</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>${jackson.version}</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>${jackson.version}</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!-- AOP --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.8.6</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.6</version> </dependency> <!-- 日志相关 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- redis --> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-redis</artifactId> <version>2.1.1.RELEASE</version> </dependency> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.10.0</version> </dependency> </dependencies>
b.创建spring.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 自动扫描的包名 --> <context:component-scan base-package="com.wode" /> <!-- 开启AOP代理 --> <aop:aspectj-autoproxy proxy-target-class="true" /> <!--开启注解处理器 --> <context:annotation-config> </context:annotation-config> <context:property-placeholder location="classpath:redis.properties"/> <!-- Spring中引入其他配置文件 --> <import resource="classpath*:/spring-redis.xml" /> </beans>
c.创建spring-redis.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd"> <!-- jedis配置 --> <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <!-- 最大空闲数：空闲连接数大于maxIdle时，将进行回收 --> <property name="maxIdle" value="${redis.maxIdle}" /> <!-- 最大连接数：能够同时建立的最大连接个数 --> <property name="maxTotal" value="${redis.maxTotal}" /> <!-- 最大等待时间：单位ms --> <property name="maxWaitMillis" value="${redis.maxWait}" /> <!-- 使用连接时，检测连接是否成功 --> <property name="testOnBorrow" value="${redis.testOnBorrow}" /> </bean> <!--cluster集群 --> <bean id="redisClusterConfiguration" class="org.springframework.data.redis.connection.RedisClusterConfiguration"> <!-- 最大重定向数目 --> <property name="maxRedirects" value="${redis.maxRedirects}"></property> <property name="clusterNodes"> <set> <bean class="org.springframework.data.redis.connection.RedisNode"> <constructor-arg name="host" value="${redis.node1.host}" /> <constructor-arg name="port" value="${redis.node1.port}" /> </bean> <bean class="org.springframework.data.redis.connection.RedisNode"> <constructor-arg name="host" value="${redis.node2.host}" /> <constructor-arg name="port" value="${redis.node2.port}" /> </bean> <bean class="org.springframework.data.redis.connection.RedisNode"> <constructor-arg name="host" value="${redis.node3.host}" /> <constructor-arg name="port" value="${redis.node3.port}" /> </bean> <bean class="org.springframework.data.redis.connection.RedisNode"> <constructor-arg name="host" value="${redis.node4.host}" /> <constructor-arg name="port" value="${redis.node4.port}" /> </bean> <bean class="org.springframework.data.redis.connection.RedisNode"> <constructor-arg name="host" value="${redis.node5.host}" /> <constructor-arg name="port" value="${redis.node5.port}" /> </bean> <bean class="org.springframework.data.redis.connection.RedisNode"> <constructor-arg name="host" value="${redis.node6.host}" /> <constructor-arg name="port" value="${redis.node6.port}" /> </bean> </set> </property> </bean> <bean id="redisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:password="${redis.password}"> <constructor-arg name="clusterConfig" ref="redisClusterConfiguration"></constructor-arg> <constructor-arg name="poolConfig" ref="jedisPoolConfig"></constructor-arg> </bean> <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"> <property name="connectionFactory" ref="redisConnectionFactory" /> <!-- 配置Serializer --> <property name="keySerializer"> <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/> </property> <property name="hashKeySerializer"> <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/> </property> <property name="valueSerializer"> <bean class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer"/> </property> <property name="hashValueSerializer"> <bean class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer"/> </property> </bean> </beans>
d.创建redis.properties
redis.password= redis.maxIdle=5 redis.maxWait=60000 redis.maxTotal=500 redis.testOnBorrow=true redis.maxRedirects=5 redis.node1.host=127.0.0.1 redis.node1.port=8081 redis.node2.host=127.0.0.1 redis.node2.port=8082 redis.node3.host=127.0.0.1 redis.node3.port=8083 redis.node4.host=127.0.0.1 redis.node4.port=8084 redis.node5.host=127.0.0.1 redis.node5.port=8085 redis.node6.host=127.0.0.1 redis.node6.port=8086
e.创建实体类
public class TestBean { private String name; private int age; public TestBean(){} public TestBean(String name, int age) { this.name = name; this.age = age; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } @Override public String toString() { return "[TestBean]: name[" + name + "], age[" + age + "]"; } }
f.使用
@Component public class TestSpringCluster { @Resource private RedisTemplate redisTemplate; public void set(String key, Object value){ // redisTemplate.boundValueOps(key).set(value); redisTemplate.opsForValue().set(key, value); } public Object get(String key){ // return redisTemplate.boundValueOps(key).get(); return redisTemplate.opsForValue().get(key); } public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml"); TestSpringCluster testSpringCluster = (TestSpringCluster) context.getBean("testSpringCluster"); testSpringCluster.set("name", "zwj"); testSpringCluster.set("age", "28"); testSpringCluster.set("bean", new TestBean("xf", 26)); String name = (String) testSpringCluster.get("name"); String age = (String) testSpringCluster.get("age"); System.out.println("name[" + name + "], age[" + age + "]"); TestBean bean = (TestBean) testSpringCluster.get("bean"); System.out.println(bean); } }
