node.js - Node : How to connect to multiple redis?

Question

如何用nodejs架设两台redis服务器(master/slave)？
我用 node_redis , 已经尝试过 redis://host:port,host2:port2?db=10&password=bar

var connectionString = 'redis://host:port,host2:port2?db=10&password=bar'
var client = redis.createClient(connectionString);
client.set('key','value',function(err,reply){
   console.log(err);  //the db option is added twice and does not match
   console.log(reply);
});

几个月后我发现ioredis可以帮助使用 nodejs 集群作业!

var Redis = require('ioredis');

var cluster = new Redis.Cluster([{
  port: 6380,
  host: '127.0.0.1'
}, {
  port: 6381,
  host: '127.0.0.1'
}]);

cluster.set('foo', 'bar');
cluster.get('foo', function (err, res) {
  // res === 'bar'
});
