Jedis连接报错

Jedis jedis = new Jedis("10.2.8.166", 6379);//操作redis服务器jedis.set("address", "beijing's sunyi");
Caused by: 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.

这时候需要为redis设置密码
127.0.0.1:6379> config get requirepass1) "requirepass"2) ""127.0.0.1:6379> config set requirepass "123456"OK

config get requirepass: 这是查询redis是否配置密码,如果返回为空，则表明未配置密码。 
config set requirepass “123456”这是将redis的密码设置为“123456”

设置好密码后，通过jedis.auth()方法连接redis服务器
Jedis jedis = new Jedis("10.2.8.166", 6379);//操作redis服务器jedis.auth("123456");jedis.set("address", "beijing's sunyi");

另外，如果设置了密码，在redis客户端操作时需要输入密码，命令为：
127.0.0.1:6379> auth "123456"
OK
不然会报错
(error) NOAUTH Authentication required.
