redis主從,實現類似mysql的讀寫分離效果。在程式碼層面需要執行slave host嗎? 目前是透過jedis客戶端JedisSentinelPool連接哨兵集群,查看日誌輸出應該連接的是master的host讀取請求會自動路由到slave嗎?
主的配置好ip和端口,從的配置好Slaveof的master地址和端口號,哨兵監控master的ip和端口號,java代碼直接master的name和密碼就行了。 `
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();
