【redis】redis的bind配置

  在配置檔案redis.conf中，預設的bind 介面是127.0.0.1，也就是本地迴環地址。這樣的話，訪問redis服務只能通過本機的客戶端連線，而無法通過遠端連線，

  這樣可以避免將redis服務暴露於危險的網路環境中，防止一些不安全的人隨隨便便通過遠端
連線到redis服務。
  如果bind選項為空的話，那會接受所有來自於可用網路介面的連線。

在使用redis的時候出現連線不成功；

在專案中匯入jar包jedis-2.7.2.jar,編寫測試類

	@Test
	public void testJedisSingle() throws Exception {
			//建立一個jedis物件
		Jedis jedis = new Jedis("192.168.64.129",6379);
		jedis.set("test", "hello jedis");
		String string = jedis.get("test");
		System.out.println(string);
		jedis.close();
	}

根據redis.conf配置檔案中bind的值的不同，出現不同的提示資訊；但是不影響Linux系統中redis的正常使用;

當不存在bind時

  redis.clients.jedis.exceptions.JedisDataException: DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.

當bind 本機ip地址時

  程式碼可以測試通過，但是Linux系統中出現問題

  [root@root redis]# ./bin/redis-cli -c
  Could not connect to Redis at 127.0.0.1:6379: Connection refused
  Could not connect to Redis at 127.0.0.1:6379: Connection refused

當bind 為預設的127.0.0.1時

  程式碼測試不通過

  redis.clients.jedis.exceptions.JedisConnectionException: java.net.ConnectException: Connection refused: connect

  Linux中操作正常

目前採用的方式，程式碼和Linux中的redis客戶端都可以使用

  1.在bind中配置多個IP地址,bind 192.168.64.129 127.0.0.1

  2.將bind的值配置為bind 0.0.0.0
