使用composer require 引入predis，宝塔上安装php的redis扩展。 配置密码：requirepass redis密码

application/extra下新建redis.php配置文件。内容如下：

/*

* Redis配置

*/

return [

'host' => '127.0.0.1', // redis 主机ip

'port' => 6379, // redis 端口

'prefix' => 'rdb_', // redis 前缀

'auth' => 'root', // redis 账号

'password' => 'redispwd', // redis 密码

'select' => 0, // 使用哪一个 db，默认为 db0

'timeout' => 0,// redis连接的超时时间

'expire' => 0,//缓存时间

'persistent' => false,// 是否是长连接

];

redis.php配置文件同级目录有队列配置文件queue.php引用了redis配置，如下：

/*

* 消息队列配置

*/

return [

'connector' => 'Redis', // Redis 驱动

'expire' => 60, // 任务的过期时间，默认为60秒; 若要禁用，则设置为 null

'default' => 'paijinhua', // 默认的队列名称

'host' => \think\Config::get("redis.host"), // redis 主机ip

'port' => \think\Config::get("redis.port"), // redis 端口

'password' => \think\Config::get("redis.password"), // redis 密码

'select' => 0, // 使用哪一个 db，默认为 db0

'timeout' => 0, // redis连接的超时时间

'persistent' => false, // 是否是长连接

];

控制器中调用redis方法：

namespace app\admin\controller;

use think\controller;

use Predis\Client;

class Index extends Controller

{

//redis 简单使用

public function index(){

$client = new Client(config('redis'));//实例化

$client->lpush('username', ['lucy','lily']);

$array = $client->get('username');

dump($array);die;

}

}
