MySQLi 未找到 dockerized php
我正在尝试对我的网站进行 dockerize.我已经启动并运行了 Nginx 和 PHP，它正在工作，但我无法连接到数据库.加载页面时出现错误:
I'm trying to dockerize my website. I've got Nginx and PHP up and running and it's working find except I can't connect to a db. When the page is loaded I get the error:
Fatal error: Uncaught Error: Class 'MySQLi' not found in /private/conn.php:8 Stack trace: #0 /public_html/index.php(2): require() #1 {main} thrown in /private/conn.php on line 8
我在第 8 行的连接线是:
My connection line on line 8 is:
$db = new mysqli("$host", "$user", "$pass", "$db", "$port");
现在这曾经在我的旧设置上运行良好，但自从转移到新设置并安装 php7.1.5 后，我无法运行它.现在，我没有使用过 mysqlnd，所以这可能是我的一个误解，但 mysqlnd 包含 mysqli 驱动程序.
Now this used to work fine on my old set up but since moving to a new one and installing php7.1.5 I can't get it running. Now, I haven't used the mysqlnd so this may be a misunderstanding on my part but the mysqlnd includes the mysqli driver.
phpinfo 的输出:
Output of phpinfo:
我怎样才能让它运行?还是我现在应该使用不同的驱动程序?
How can I get this running? Or should I be using a different driver now?
推荐答案
您需要在 Dockerfile 中启用 php 扩展:
You need to enable the php extension in your Dockerfile:
FROM php:7
RUN docker-php-ext-install mysqli
无需触摸php.ini.
