Redis集群密码设置

在网上查到一种方式，修改所有Redis集群中的redis.conf文件，加入：

masterauth <yourpassword>
requirepass <yourpassword>

这种方式需要重新启动各节点,比较麻烦
另一种方式我们可以进入每一个节点，输入如下指令：

./redis-cli -c -h bigdata24 -p 8000 
config set masterauth <yourpassword>
config set requirepass <yourpassword>
config rewrite 

这种方式rewrite不知道有没有意义，因为在执行config set requirepass yourpassword该指令之后运行config rewrite会提示错误
(error) NOAUTH Authentication required.
原因，没有是没有进行密码认证，输入auth <yourpassword>就可以啦

使用JedisCluster访问Redis集群

public class JedisClusterUtil {

        private static volatile JedisCluster cluster;

        private JedisClusterUtil() {}

        public static JedisCluster getInstance() {
            if (cluster == null) {
                synchronized (JedisClusterUtil.class) {
                    if (cluster == null) {
                        Set<HostAndPort> nodes = new LinkedHashSet<>();
                        nodes.add(new HostAndPort("bigdata24", 8000));
                        nodes.add(new HostAndPort("bigdata24", 8001));
                        nodes.add(new HostAndPort("bigdata24", 8002));
                        nodes.add(new HostAndPort("bigdata24", 8003));
                        nodes.add(new HostAndPort("bigdata24", 8004));
                        nodes.add(new HostAndPort("bigdata24", 8005));
                        cluster = new JedisCluster(nodes,5000,3000,10,"cltest", new JedisPoolConfig());
                        return cluster;
                    }
                }
            }
            return cluster;
        }
}

JedisCluster参数

public JedisCluster(Set<HostAndPort> jedisClusterNode, int connectionTimeout, int soTimeout,int maxAttempts, String password, final GenericObjectPoolConfig poolConfig) {
    super(jedisClusterNode, connectionTimeout, soTimeout, maxAttempts, password, poolConfig);
  }
