tp5实现多个redis连接一种方法(tp5多个redis)

tp5可以使用连接多个redis实现高可用性的开发。本文介绍一种实现多个redis连接的方法。

假设redis服务器的IPs为:127.0.0.1:6379,127.0.0.1:6380,把这两台服务器的redis连接配置参数在tp5的config配置文件中配置 avlable_connections数组:

// config.php

return [

‘redis’ => [

‘default’ => [],

‘options’ => [

‘cluster’ => ‘redis’,

‘prefix’ => ‘tp5_’,

],

// 指定多个redis连接实例

‘avlable_connections’ => [

‘default’ => [

[

‘driver’ => ‘redis’,

‘host’ => ‘127.0.0.1’,

‘port’ => 6379,

‘database’ => 0,

],

[

‘driver’ => ‘redis’,

‘host’ => ‘127.0.0.1’,

‘port’ => 6380,

‘database’ => 0,

],

],

],

],

];

针对两个redis连接实例,可以通过tp5框架提供的封装功能实现对redis数据库的高可用读写操作。可以定义出两个类RedisManager.php,RedisClient.php:

// RedisManager.php类

public static function getRediser($tn)

{

if (count(self::$sessionStorageArray) > 0) {

$maxCount = self::$maxCount;

$count = self::$count % $maxCount;

if (isset(self::$sessionStorageArray[$count])) {

return self::$sessionStorageArray[$count];

}

} else {

$configs = Config::get(‘redis.avlable_connections.’ . $tn);

$sessionStorage = new SessionStorage($tn);

// 遍历可用redis连接,实现多个Redis连接的读写操作

foreach ($configs as $config) {

$sessionStorage->addSingleStorage($config);

}

self::$sessionStorageArray[] = $sessionStorage;

}

return self::$sessionStorageArray[0];

}

定义RedisClient.php类,封装get,set,del等redis操作,并在调用的时候动态切换tp5的redis连接,实现多个redis连接的高可用读写操作:

//RedisClient.php类

public function set($key, $value, $expire = 0)

{

$activeRet = false;

$ret = false;

$Redis = Tp5RedisManager::getRediser(‘default’);

try {

$activeRet =$Redis->getPredis()->set($key, $value, $expire);

$ret = true;

} catch (\Exception $e) {

$ret = false;

$activeRet = ”;

throw new \think\Exception(‘redis set error:’ . $e->getMessage());

} finally {

return [$ret, $activeRet];

}

}

综上,tp5框架可以实现多个redis连接操作,从而提高应用的可用性和性能,实现高可用的开发。
