title: How to connect to redis sentinel and manipulate different dbs
body: <p>I am struggling to connect redis in sentinel mode using redis-cli.</p>
  <p>I've tried:</p>
  <p><code>redis-cli -h my_host -p my_port -a my_password</code></p>
  <p>I randomly picked up one from 3 sentinel nodes to connect.</p>
  <p>However, when logged in, it seems different with single mode redis, where I can manipulate dbs with <code>set</code> or <code>hset</code> commmand.</p>
  <p>For instance, when I am typing:</p>
  <p><code>select 0</code> (trying to select db 0)</p>
  <p>It returns:</p>
  <pre><code>redis_sentinel_node_1_ip:port&gt; select 0
  (error) ERR unknown command `select`, with args beginning with: `0`
  </code></pre>
  <p>Could anyone help ?</p>
