命令行直接连：
redis-cli -h host -a 6379:password
php扩展：
$redis = new Redis();
$redis->connect(host,6379);
$res = $redis->auth(password);
<?php
//Connecting to Redis server on localhost
$redis = new Redis();
$redis->connect('host', 6379);
echo "Connection to server sucessfully";
//check whether server is running or not echo "Server is running: "+ $redis->ping();
?>
