1、修改数据库配置database.php文件，将break_reconnect参数设置为true。断线重连。

'break_reconnect' => true,

2、修改 /library/think/db/Connection.php中的isBreak函数，替换为以下最新的isBreak函数。

/**
 * 是否断线
 * @access protected
 * @param \PDOException|\Exception  $e 异常对象
 * @return bool
 */
protected function isBreak($e)
{
    if (!$this->config['break_reconnect']) {
        return false;
    }

    $info = [
        'server has gone away',
        'no connection to the server',
        'Lost connection',
        'is dead or not enabled',
        'Error while sending',
        'decryption failed or bad record mac',
        'server closed the connection unexpectedly',
        'SSL connection has been closed unexpectedly',
        'Error writing data to the connection',
        'Resource deadlock avoided',
        'failed with errno',
    ];

    $error = $e->getMessage();

    foreach ($info as $msg) {
        if (false !== stripos($error, $msg)) {
            return true;
        }
    }
    return false;
}

3、将/library/think/db/connector/Mysql.php中的isBreak函数删除或者注释掉。
