cent7.3离线安装oracle19c

需要准备的安装包下载

oracle-database-ee-19c-1.0-1.x86_64.rpm

oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

下载依赖

compat-libstdc -33-3.2.3-72.el7.x86_64.rpm

下载yum镜像包

http://mirrors.163.com/centos-vault/

(CentOS-7-x86_64-DVD-1611.iso)

先配置yum源为本地镜像的CentOS-7-x86_64-DVD-1611.iso文件

参考https://blog.csdn.net/xtaypyvi123456/article/details/124688172

安装compat-libstdc -33-3.2.3-72.el7.x86_64.rpm，iso文件里面有没，需要独立下载安装

然后安装oracle，可能遇到bind版本不匹配，卸载自带了安装新的即可

yum localintstall oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

接着安装

yum localintstall oracle-database-ee-19c-1.0-1.x86_64.rpm

[root@localhost ~]# vi /etc/sysconfig/oracledb_ORCLCDB-19c.conf

如果需要修改端口课编辑这个文件

[root@localhost ~]# vi /etc/init.d/oracledb_ORCLCDB-19c

初始化
