我在服务器上安装了CentOS Linux release 8.0.1905 (Core)，安装了nginx，php，php-fpm，并进行了配置，一切正常。
问题在于，现在我需要安装oci8软件包，而在AppStream / BaseOs上找不到它：
sudo yum install php-oci8
Última verificação de data de vencimento de metadados: 0:22:32 atrás em seg 04 nov 2019 09:55:00 -03.
Nenhuma correspondência para argumento: php-oci8
Erro: Não foi possível encontrar uma correspondência
如何在CentOS8上查找并安装php-oci8？
如果仍然存在此问题，则可以先安装所有oracle软件包：
