redis主从,实现类似mysql的读写分离效果。在代码层面需要执行slave host吗?目前是通过jedis客户端JedisSentinelPool连接哨兵集群,查看日志输出应该连接的是master的host读请求会被自动路由到slave吗?
主的配置好ip和端口,从的配置好Slaveof的master地址和端口号,哨兵监控master的ip和端口号,java代码直接master的name和密码就行了。`
public static void main(String[] args) { Set<String> sentinels = new HashSet<String>(); String hostAndPort1 = "127.0.0.1:26379"; String hostAndPort2 = "127.0.0.1:26380"; sentinels.add(hostAndPort1); sentinels.add(hostAndPort2); String clusterName = "mymaster"; String password = "123456"; JedisSentinelPool redisSentinelJedisPool = new JedisSentinelPool(clusterName,sentinels,password); Jedis jedis = null; try { jedis = redisSentinelJedisPool.getResource(); System.out.println(jedis.get("key")); } catch (Exception e) { e.printStackTrace(); } finally { redisSentinelJedisPool.returnBrokenResource(jedis); } redisSentinelJedisPool.close();
