用外网搭建redis集群总结

用外网搭建redis集群总结

一、在配置文件redis-cluster.conf配置内网

二、在云主机的防火规则开放端口：8000、8001、8002、8003、8004、8005和18000、18001、18002、18003、18004、18005

• 三、用外网ip搭建集群节点的三主三从脚本

for port in {8000..8005};do redis-cli -c -p $port shutdown;done;

rm -rf dump*;

rm -rf appendonly*;

rm -rf nodes*;

for port in {8000..8005};do redis-server $port/redis-cluster.conf;done;

echo yes|./src/redis-trib.rb create --replicas 1 116.75.179.72:8000 116.75.179.72:8001 116.75.179.72:8002 116.75.179.72:8003 116.75.179.72:8004 116.75.179.72:8005;

四、用外网ip连接集群测试

package cn.tedu;

import org.junit.Test;

import redis.clients.jedis.HostAndPort;

import redis.clients.jedis.JedisCluster;

import redis.clients.jedis.JedisPoolConfig;

import java.util.HashSet;

import java.util.Set;

public class JedisClusterTest {

    @Test

    public void test01(){

        //收集集群的节点信息，至少要提供一个可连接的节点

        Set<HostAndPort> set=new HashSet<HostAndPort>();

        set.add(new HostAndPort("116.75.179.72",8001));

        //内部封装连接池，可以提供一个连接池配置对象

        JedisPoolConfig config=new JedisPoolConfig();

        config.setMaxIdle(8);

        config.setMinIdle(3);

        config.setMaxTotal(200);

        //使用上述2个参数构造一个集群连接对象jedisCluster

        JedisCluster cluster=new JedisCluster(set,config);

        //调用cluster方法 底层发送redis命令 set get hset hget lpush..

       cluster.set("name9","王老师9");

       System.out.println(cluster.get("name9"));

    }

}

五、项目的userservice系统配置用外网ip连接：

server.port=10003

server.context-path=/

#datasource

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.datasource.url=jdbc:mysql:///easydb

spring.datasource.username=root

spring.datasource.password=root

#sqlSession classpath:==roottarget/classes src/main/resources/mapper

mybatis.mapper-locations=classpath:mapper/*.xml

mybatis.type-aliases-package=com.jt.common.pojo

#mybatis single config

mybatis.configuration.map-underscore-to-camel-case=true

mybatis.configuration.cache-enabled=false

#eureka config

spring.application.name=userservice

eureka.client.service-url.defaultZone=http://localhost:8888/eureka

#redis config

redis.nodes=116.75.179.73:6379,116.75.179.73:6380,116.75.179.72:6381

redis.maxTotal=200

redis.maxIdle=8

redis.minIdle=5

#cluster config

cluster.nodes=116.75.179.72:8000,116.75.179.72:8001,116.75.179.72:8002

cluster.maxTotal=200

cluster.maxIdle=8

cluster.minIdle=5
