使用 EasyApache4 在 CENTOS 6.9 上启用 PDO 模块

Question

我已经使用 EasyApache4 在 Centos 6.9 上运行的 VPS 服务器上安装了 7.1.7-1.1.1.cpanel 和 7.0.21-1.1.1.cpanel。我有一个 laravel API 和一个 angular4 应用程序，我想在服务器上运行，但我无法让 PHP 正常运行。使用 git 安装站点后出现错误；

找不到驱动程序 (SQL: select * from site_menu_placements where active = 1)

我检查了 error_log，发现以下内容对我来说没有多大意义；

我认为该错误对应于 php_pdo_mysql.dll 未正常运行。我检查了 phpinfo() 并看到主 php.ini 文件位于 /opt/cpanel/ea-php71/root/etc 我试图在此文件中加载 PDO 模块，但即使我有也没有效果；

extension=pdo.so
extension=pdo_mysql.so
extension=pdo_sqlite.so
extension=mysql.so

当我查看 phpinfo() 页面时，我可以看到有一个名为“PDO”的部分，但在此部分中，我只看到 PDO 驱动程序行中的 sqlite。我相信我也应该看到mysql。

当我通过 ssh 运行 php artisan migrate 时，出现以下错误；

[Doctrine\DBAL\Driver\PDOException] 找不到驱动程序

[PDOException] 找不到驱动程序

我认为应该包含 pdo mysql 驱动程序的包是ea-php71-php-pdo-7.1.7-1.1.6.cpanel.x86_64 我使用rpm -ql ea-php71-php-pdo-7.1.7-1.1.6.cpanel.x86_64 找出它的安装位置，我得到以下信息；

/opt/cpanel/ea-php71/root/etc/php.d/20-pdo.ini
/opt/cpanel/ea-php71/root/etc/php.d/20-sqlite3.ini
/opt/cpanel/ea-php71/root/etc/php.d/30-pdo_sqlite.ini
/opt/cpanel/ea-php71/root/usr/lib64/php/modules/pdo.so
/opt/cpanel/ea-php71/root/usr/lib64/php/modules/pdo_sqlite.so
/opt/cpanel/ea-php71/root/usr/lib64/php/modules/sqlite3.so

所以 pdo_mysql 丢失了。

Answer 1

按照说明进行操作：

第一步：在命令行运行pecl install pdo

第 2 步： 如果已经安装，只需编辑 /etc/php.ini

第 3 步：添加以下行

; Extension PDO
extension=pdo.so

第二种方式：

先安装php-mysql

sudo apt-get install php7.0-mysql

然后启用模块

sudo phpenmod pdo_mysql

然后重启apache

sudo service apache2 restart 

希望它会有所帮助。
