一、前言
本文章通过关于java的jedis(2.6.0)的redis客户端连接驱动包，对配置的redis哨兵+主从读写模式配置进行示例代码验证，详细参见具体配置步骤&示例代码说明部分。
二、配置步骤
1. 安装redis(参考其他文章教程),并配置主从模式(参考其他相关文章，这里分别在本地通过配置进行模拟三台主从服务器，端口分别为6379、7380、6381)
2. 从解压安装文件复制sentinel.conf文件模板(具体操作如下，这边在一台服务器(192.168.1.202)上模拟三个sentinel哨兵服务器配置，分别对应下面的sentinel26379.conf 、sentinel26380.conf、sentinel26381.conf 配置文件)[root@centos6 redis-4.0.2]# cp /home/soft/redis-4.0.2/sentinel.conf /etc/redis/sentinel26379.conf@b@[root@centos6 redis-4.0.2]# cp /home/soft/redis-4.0.2/sentinel.conf /etc/redis/sentinel26380.conf@b@[root@centos6 redis-4.0.2]# cp /home/soft/redis-4.0.2/sentinel.conf /etc/redis/sentinel26381.conf
3. 分别修改sentinel26379.conf 、sentinel26380.conf、sentinel26381.conf配置..@b@#三个配置文件，分别设置为23679、26380、26381@b@port 26379@b@@b@...@b@@b@#三个配置文件相同@b@sentinel monitor mymaster 192.168.1.202 6381 1@b@...@b@#三个配置文件相同,其中密码根据情况进行设置，这边不用密码，另外6380、6379是在本地模拟两台redis的slave备用服务器@b@#sentinel auth-pass mymaster 123456@b@sentinel config-epoch mymaster 2237@b@sentinel leader-epoch mymaster 2237@b@sentinel known-slave mymaster 192.168.1.202 6380@b@sentinel known-slave mymaster 192.168.1.202 6381@b@@b@sentinel failover-timeout mymaster 18000@b@sentinel down-after-milliseconds mymaster 5000@b@@b@#下面redis-sentinel启动自动生成，无需手动配置@b@sentinel known-sentinel mymaster 192.168.1.202 26380 51df014024045d5382a408c4afe1f9c3287bd0e3@b@sentinel known-sentinel mymaster 192.168.1.202 26381 a3b1a33e0d2dbe70b8de78dba808a1e0a6e6fc5c@b@sentinel known-sentinel mymaster 192.168.1.202 26379 3deef21eea5f4a5198f71236bd1d0fc859c28ff7
4. 先启动三台redis主从服务器，再分别启动哨兵服务器，具体启动脚本顺序参考如下[root@centos6 redis]# /usr/local/bin/redis-server /etc/redis/6379.conf@b@[root@centos6 redis]# /usr/local/bin/redis-server /etc/redis/6380.conf@b@[root@centos6 redis]# /usr/local/bin/redis-server /etc/redis/6381.conf[root@centos6 redis]# /usr/local/bin/redis-sentinel /etc/redis/sentinel26379.conf --protected-mode no@b@[root@centos6 redis]# /usr/local/bin/redis-sentinel /etc/redis/sentinel26380.conf --protected-mode no@b@[root@centos6 redis]# /usr/local/bin/redis-sentinel /etc/redis/sentinel26381.conf --protected-mode no
三、代码示例package com.xwood.redis.sentinel;@b@@b@import java.util.HashSet;@b@import java.util.Set;@b@@b@import redis.clients.jedis.Jedis;@b@import redis.clients.jedis.JedisSentinelPool;@b@@b@public class RedisSentinelTest {@b@@b@ private static JedisSentinelPool jSentinelPool;@b@@b@ public static void main(String[] args) throws Exception{ @b@ @b@ Set sentinels = new HashSet(); @b@ sentinels.add("192.168.1.202:26379");@b@ sentinels.add("192.168.1.202:26380");@b@ sentinels.add("192.168.1.202:26381");@b@ @b@ String clusterName = "mymaster" ; @b@ @b@ JedisSentinelPool jsentinelPool = new JedisSentinelPool(clusterName,sentinels); @b@ Jedis jedis = null; @b@ try { @b@ jedis = jsentinelPool.getResource(); @b@ jedis.set("key", "aaa"); @b@ while(true){@b@ @b@ try { @b@ System.out.println(jedis.getClient().getHost()+":"+jedis.getClient().getPort()+"@"+jedis.get("key"));@b@} catch (Exception e) {@b@ System.out.println("getConntion error,waiting 5s,will try again..."+e.getMessage());@b@ Thread.sleep(5000);@b@ try {@b@jedis = jsentinelPool.getResource();@b@} catch (Exception e1) {@b@System.out.println("getResource error2,waiting more,will try again..."+e.getMessage());@b@} @b@} @b@ Thread.sleep(2000);@b@ }@b@ @b@ @b@ } catch (Exception e) { @b@ e.printStackTrace(); @b@ } finally { @b@ jedis.close(); @b@ } @b@ jsentinelPool.close(); @b@ } @b@ @b@@b@}
