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。
