一、下载yum源

根据自己需求下载相应的yum源

http://yum.oracle.com/getting-started.html

我的系统是 centos7.3，所以就选择linux7。

# cd /etc/yum.repos.d
# wget http://yum.oracle.com/public-yum-ol7.repo

二、安装RMP-GPG-KEY

wget http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol7 -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle

这个不安装可能会出现yum源验证失败的问题。

三、安装oracle

查看是否有你所需要的安装程序

[root@localhost yum.repos.d]# yum list |grep oracle
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration
oracle-rdbms-server-11gR2-preinstall.x86_64
kmod-oracleasm.x86_64 2.0.8-19.el7 base
oracle-database-server-12cR2-preinstall.x86_64
oracle-logos.noarch 70.0.3-4.0.7.el7 ol7_u0_base
oracleasm-support.x86_64 2.1.8-3.1.el7 ol7_u3_base
oraclelinux-release.x86_64 7:7.3-1.0.4.el7 ol7_u3_base
pcp-pmda-oracle.x86_64 3.11.8-7.el7 base
tuned-profiles-oracle.noarch 2.8.0-5.el7_4.2 updates

我们安装 oracle-rdbms-server-11gR2-preinstall.x86_64

[root@localhost yum.repos.d]# yum install -y oracle-rdbms-server-11gR2-preinstall
