步骤1.安装构建自定义PHP 7模块所需的devel包
# yum install plesk-php70-devel gcc glibc-devel libmemcached-devel zlib-devel make libaio.x86_64
步骤2.下载oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm和oracle-instantclient12.1-devel-12.1.0.2.0-1.x86_64.rpm（来自Oracle OTN），并将其上传到服务器上。、

步骤3.安装oracle-instantclient12 *包:
# rpm -Uhv oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm oracle-instantclient12.1-devel-12.1.0.2.0-1.x86_64.rpm
步骤4.用pecl安装oci8包
# /opt/plesk/php/7.0/bin/pecl install oci8
步骤5.在php.ini中启用oci8模块
# echo "extension=oci8.so" > /opt/plesk/php/7.0/etc/php.d/oci.ini
要为通过Plesk安装的其他PHP引擎安装oci8扩展，请为相应的PHP版本安装PHP devel包。
例如，对于PHP 7.2:
# yum install plesk-php72-devel
重复上面的步骤4,5，确保路径是当前PHP版本的:
# /opt/plesk/php/7.2/bin/pecl install oci8 # echo "extension=oci8.so" > /opt/plesk/php/7.2/etc/php.d/oci.ini
检查扩展是否已启用:
# /opt/plesk/php/7.2/bin/php -m | grep oci oci8
