本文详细介绍了在CentOS 7上安装Oracle 12cR2的步骤，包括解决yum安装预装包时的错误，创建Oracle安装目录，设置环境变量，创建启动脚本，并编写systemd服务脚本以实现开机启动。

1，安装oracle-database-server-12cR2-preinstall

wget http://public-yum.oracle.com/public-yum-ol7.repo -O /etc/yum.repos.d/public-yum-ol7.repo
wget http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol7 -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
yum -y install oracle-database-server-12cR2-preinstall

yum -y install oracle-database-server-12cR2-preinstall 这一步一般会报如下错误：
