Question

最近在Ubuntu 16 x64盒子上安装了php7.0-fpm + Nginx + MySQL。

当将PDO安装程序发送到数据库以便添加文件时，它会执行以下操作：

There seems to be an error. Please try again.
PDOException: SQLSTATE[42000]: Syntax error or access violation: 1067 Invalid default value for 'expiry_date' in /var/www/mcdospace/install/index.php:31 Stack trace: #0 /var/www/mcdospace/install/index.php(31):

我在设置中遗漏了什么吗？它在Ubuntu 14 php5系统上运行良好。

下面是一些表插入以帮助评估：

'0' => array(
                'table' => TABLE_FILES,
                'query' => 'CREATE TABLE IF NOT EXISTS `'.TABLE_FILES.'` (
                              `id` int(11) NOT NULL AUTO_INCREMENT,
                              `url` text NOT NULL,
                              `filename` text NOT NULL,
                              `description` text NOT NULL,
                              `timestamp` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP(),
                              `uploader` varchar('.MAX_USER_CHARS.') NOT NULL,
                              `expires` INT(1) NOT NULL default \'0\',
                              `expiry_date` TIMESTAMP NOT NULL,
                              `public_allow` INT(1) NOT NULL default \'0\',
                              `public_token` varchar(32) NULL,
                              PRIMARY KEY (`id`)
                            ) ENGINE=InnoDB  DEFAULT CHARSET=utf8 COLLATE=utf8_general_ci;
                            ',
                'params' => array(),
    ),

对于expiry_date列，not null约束没有任何默认值会导致默认设置为0，这在MySQL中不作为时间戳的默认值接受。

使用expiry_date字段的默认时间戳。

您可以查看有关此问题的以下主题的讨论。
