Oracle Database 21c RPM安装体验

考虑在云上和idc机房都可以适配，操作系统可以选择

Red Hat Enterprise Linux 8.2: 4.18.0-193.19.1.el8_2.x86_64 or later

实际选择了兼容的CentOS做测试

cat /etc/redhat-release

CentOS Linux release 8.2.2004 (Core)

uname -r

4.18.0-193.el8.x86_64

网络配置

如果有故障，试着修改配置，然后重启网络

cat /etc/sysconfig/network-scripts/ifcfg-ens33  
cat /etc/resolv.conf  

nmcli c  
nmcli c up ens33  
nmcli device show  

安装基本依赖包

yum install -y telnet unzip wget curl

安装oracle-database-preinstall包

oracle-database-preinstall-21c-1.0-1.el8.x86_64.rpm 没发布，用19c的也可以

wget https://yum.oracle.com/repo/OracleLinux/OL8/appstream/x86_64/getPackage/oracle-database-preinstall-19c-1.0-2.el8.x86_64.rpm

yum -y localinstall oracle-database-preinstall-19c-1.0-2.el8.x86_64.rpm

安装日志见:/var/log/oracle-database-preinstall-19c/results/orakernel.log

用RPM包安装21c数据库

yum装,失败

[root@centos82 tmp]# yum -y localinstall oracle-database-ee-21c-1.0-1.ol8.x86_64.rpm

换rpm装
