解决方案-不需要证书，只需在客户端启用TLS（例如，ioredis只需具有tls: {}

下面是我使用Predis的工作演示代码。

$servers = ['tls://master.my-test-redis.8juowe.euw2.cache.amazonaws.com:6379']; // your endpoint
$options = ['parameters' => ['password' =>   $password ]]; // put your password here
$redis   = new Predis\Client($servers, $options ); // Instance your client
