【CPU】:Intel(R) Core(TM) i9-8950HK
【问题描述】*：用PHP 8.0.30版本（Zend Engine v4.0.30）分别调用达梦在安装包中提供的libphp80_dm.so和php80_pdo_dm.so，相应的PHP组件php-fpm不能启动，分别报如下错误：

PHP Fatal error: Unable to start dm module in Unknown on line 0
php-fpm.service: Main process exited, code=exited, status=254/n/a
php-fpm.service: Failed with result 'exit-code'.
Failed to start The PHP FastCGI Process Manager.

PHP Fatal error: Unable to start PDO_DM module in Unknown on line 0
php-fpm.service: Main process exited, code=exited, status=254/n/a
php-fpm.service: Failed with result 'exit-code'.
Failed to start The PHP FastCGI Process Manager.

同时，在php -info中：
PDO_DM（php80_pdo_dm.so）
PDO Driver for DM (Unknown) => enabled
DM Connection Pooling => Not supported in this build

libphp80_dm.so未报类似信息

[root@uosdms system]# more /usr/lib/systemd/system/php-fpm.service
It's not recommended to modify this file in-place, because it
will be overwritten during upgrades. If you want to customize,
the best way is to use the "systemctl edit" command.
