node.js - nodejs ioredis All sentinels are unreachable

如题, 在使用 ioredis 链接 redis的哨兵是,报错 All sentinels are unreachable, 代码示例如下:

const Redis = require('ioredis');

let redis = new Redis({
    sentinels: [
        { host: 'XXX', port: XX },
        { host: 'XXX', port: XX },
        { host: 'XX', port: XX },
    ],
    name: 'mymaster',
    connectTimeout: 1000,
});

redis.select(1);
// console.log(redis);
redis.set('foo', 'hello world');

redis.get('foo', (err, result) => {
    console.log(result);
})
