### 锁

[](#锁)

加锁是访问临界资源时对资源的保护机制，加锁的目的是对并发访问和并发请求进行保护，未获取到锁的请求将无权操作资源。

> 临界区域指的是一块对公共资源进行访问的代码，并非一种机制或是算法。一个程序、进程、线程可以拥有多个临界区域

### 安装

[](#安装)

```
composer require happysir/distributed-lock
```

### 配置

[](#配置)

```
use Happysir\Lock\RedisLock;
use Swoft\Redis\Pool;
use Swoft\Redis\RedisDb;

        'class'    => RedisDb::class,
        'host'     => '127.0.0.1',
