Question

我已将我的项目从AWS迁移到Google Cloud。我之前有一个工作应用程序，但现在迁移到GCP后， mysqli_connect 似乎不再起作用。到目前为止，我已经安装了以下内容：

PHP-MySQL的-5.4.16-42.el7.x86_64
PHP-PDO-5.4.16-42.el7.x86_64
PHP-5.4.16-42.el7.x86_64
php-common-5.4.16-42.el7.x86_64
PHP-CLI-5.4.16-42.el7.x86_64
MariaDB的-库-5.5.52-1.el7.x86_64
MariaDB的-5.5.52-1.el7.x86_64

我可以使用终端访问MySQL但无法使用PHP连接到远程数据库（在AWS RDS上）。 RDS数据库对IP连接没有任何限制，并向全世界开放。我已经尝试完全删除PHP，MySQL，MariaDB，但是没有成功。迁移后，连接到数据库的脚本保持不变。其他功能，如 mysqli_fetch_assoc 和 mysqli_query 不会引发任何错误。以下是 mysqld_log ：

Answer 1

你写的是你使用了mysqli_connect，但是你已经安装了php-mysql-5.4.16-42.el7.x86_64（注意：没有＆＃39; i＆＃39;）。您需要mysqli的包才能连接PHP。

MySQL适用于终端但不适用于PHP
