Redis集群配置和部署 spring整合redisCluster

Redis 集群配置和部署

1.  下载redis3.0

2.  上传服务器，解压，编译（前两步与之前相同）http://blog.csdn.net/liguangyan_neu/article/details/78026932 参考2.1节

3.  创建集群需要的目录

mkdir /usr/local/cluster

cd  /usr/local/cluster

mkdir  7000 7001 7002 7003 7004 7005

4.  修改配置文件redis.conf

cp  /usr/local/redis3.0.5/redis.conf  /usr/local/cluster

vi  redis.conf

修改配置文件中如下选项

port  7000

daemonize  yes

cluster-enabled  yes

cluster-config-file  nodes.conf

cluster-node-timeout  5000

appendonly  yes

修改完配置文件后将redis.conf 文件分别拷贝至 7000 、 7001……7005 目录下

cp  /usr/local/cluster/redis.conf  /usr/local/cluster/7000

cp  /usr/local/cluster/redis.conf  /usr/local/cluster/7001

cp  /usr/local/cluster/redis.conf  /usr/local/cluster/7002

cp  /usr/local/cluster/redis.conf  /usr/local/cluster/7003

cp  /usr/local/cluster/redis.conf  /usr/local/cluster/7004

cp  /usr/local/cluster/redis.conf  /usr/local/cluster/7005

拷贝结束之后分别修改对应的配置文件中的端口port 为对应的端口号

5.  分别启动六个redis 实例

/usr/local/redis-3.0.5/src/redis-server /usr/local/cluster/7000/redis.conf

/usr/local/redis-3.0.5/src/redis-server /usr/local/cluster/7001/redis.conf

/usr/local/redis-3.0.5/src/redis-server /usr/local/cluster/7002/redis.conf

/usr/local/redis-3.0.5/src/redis-server /usr/local/cluster/7003/redis.conf

/usr/local/redis-3.0.5/src/redis-server /usr/local/cluster/7004/redis.conf

/usr/local/redis-3.0.5/src/redis-server /usr/local/cluster/7005/redis.conf

查看启动情况

ps  -ef|grep redis

6.  升级ruby 安装 gem

7. gem 安装 redis ruby 接口

8.  执行redis 创建集群命令创建集群

/usr/local/redis-3.0.5/src/redis-trib.rb create --replicas 1 192.168.1.191:7000 192.168.1.191:7001 192.168.1.191:7002 192.168.1.191:7003  192.168.1.191:7004  192.168.1.191:7005

9.  进入集群环境使用redis-cli

/usr/local/redis-3.0.5/src/redis-cli -c -h 192.168.1.191 -p 7000

 

10. RedisCluster 客户端（ Jedis ）

使用spring 集成 JedisCluster 连接 Redis3.0 集群

Ø  Maven 依赖

redis.clients

jedis

2.7.2

 

Ø  增加spring 配置

"genericObjectPoolConfig"   class = "org.apache.commons.pool2.impl.GenericObjectPoolConfig"  >  

        "maxWaitMillis"  value= "-1"  />  

         "maxTotal"  value= "1000"  />  

        "minIdle"  value= "8"  />  

        "maxIdle"  value= "100"  />  

  

  

"jedisCluster"   class = "xxx.JedisClusterFactory" >  

     "addressConfig" >  

        classpath:connect-redis.properties  

      

     "addressKeyPrefix"  value= "address"  />     

      

     "timeout"  value= "300000"  />  

     "maxRedirections"  value= "6"  />  

     "genericObjectPoolConfig"  ref= "genericObjectPoolConfig"  />  

 

Ø  增加 connect-redis.properties 配置文件

address1= 192.168.1.191:7000   

address2= 1 92.168.1.191:7001  

address3= 1 92.168.1.191:7002   

address4= 1 92.168.1.191:7003    

address5= 1 92.168.1.191:7004    

address6= 1 92.168.1.191:7005   

 

Ø  增加java 类 JedisClusterFactory

1. import  java.util.HashSet;

50.   

51.                  if  (!((String) key).startsWith(addressKeyPrefix)) {  

52.                      continue ;  

53.                 }  

54.   

55.                 String val = (String) prop.get(key);  

56.   

57.                  boolean  isIpPort = p.matcher(val).matches();  

58.   

59.                  if  (!isIpPort) {  

60.                      throw   new  IllegalArgumentException( "ip  或  port  不合法 " );  

61.                 }

63.   

64.                 HostAndPort hap =  new  HostAndPort(ipAndPort[ 0 ], Integer.parseInt(ipAndPort[ 1 ]));  

65.                 haps.add(hap);  

66.             }  

67.   

68.              return  haps;  

69.         }  catch  (IllegalArgumentException ex) {  

70.              throw  ex;
