1 说明
1.1 前言
本文是Linux系统命令行模式安装Oracle数据库的学习实验记录，根据真实环境操作进行记录。具备较强的可操作性、可重复性。
本次实验在虚拟机环境中完成，Oracle数据库通过在Linux命令行方式安装。
本文主要用实操实验方式探究Linux命令行安装Oracle数据库过程。对虚拟机软件安装、虚拟机下Linux环境搭建不做详细展开。
1.2 资源下载
1、虚拟机软件版本：本文使用VMware Workstation 17 Pro
2、操作系统版本：一键下载
[root@localhost proc]# cat /etc/redhat-release
CentOS Linux release 8.5.2111
3、数据库版本：一键下载
本文使用Oracle 19C,具体版本为
19.3 - Enterprise Edition (also includes Standard Edition 2)
4、预安装包下载：参考2.2章节
5、本文相关资料已上传站内，可通过百度网盘下载全部内容。

2 安装步骤
2.1 上传安装包
创建目录，通过SecureFX将数据库安装包上传至服务器。
大家如果遇到上传相关问题，可留言咨询。看到必回。
//创建目录
[root@localhost proc]# mkdir -p /oracle/install
//对目录赋权
[root@localhost proc]# chmod -R 777 /oracle/install
--说明：此时可将文件上传至/Oracle/install目录。
遗留问题：虚拟网卡传输速度为何限制为100M？
2.2 下载数据库预安装包
命令：
wget http://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
实际操作：
[root@localhost install]# pwd
/oracle/install
[root@localhost install]# ls
oracle-database-ee-19c-1.0-1.x86_64.rpm
[root@localhost install]# wget http://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

2.3 安装数据库预安装包
1、安装命令:
yum -y localinstall oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
2、第一次安装报错：
[root@localhost install]# yum -y localinstall oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
CentOS Linux 8 - AppStream 62 B/s | 38 B 00:00
Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist
3、解决第一次报错，参考：点击跳转。主要操作步骤如下：
//进入yum的repos目录
cd /etc/yum.repos.d/
//修改 centos 文件内容
sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*
//生成缓存更新
yum makecache
//运行yum update（该步骤较慢）
yum update -y
//返回安装目录重新执行命令
[root@localhost yum.repos.d]# cd /oracle/install/
[root@localhost install]# ls
oracle-database-ee-19c-1.0-1.x86_64.rpm oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
[root@localhost install]# yum -y localinstall oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
4、再次执行，出现第二次报错：
[root@localhost install]# yum -y localinstall oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
Last metadata expiration check: 0:06:14 ago on Sat 24 Jun 2023 08:58:15 AM PDT.
Error:
Problem: conflicting requests
- nothing provides compat-libcap1 needed by oracle-database-preinstall-19c-1.0-1.el7.x86_64
- nothing provides compat-libstdc++-33 needed by oracle-database-preinstall-19c-1.0-1.el7.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
5、解决第二次报错：参考文章跳转
//尝试忽略，但是安装未成功。
[root@localhost install]# yum install --skip-broken oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
Last metadata expiration check: 0:04:39 ago on Sat 24 Jun 2023 09:08:19 AM PDT.
Dependencies resolved.
Nothing to do.
Complete!
//根据参考文章执行命令
[root@localhost install]# sudo rpm -ivh oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
warning: oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY
error: Failed dependencies:

//果然如文章所言存在异常，先执行这个，在执行上面步骤
curl -o compat-libcap1-1.10-7.el7.x86_64.rpm http://mirror.centos.org/centos/7/os/x86_64/Packages/compat-libcap1-1.10-7.el7.x86_64.rpm
//并没有用。
sudo rpm -ivh oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm --force --nodeps
6、解决过程存在问题。参考下面文章解决：点击跳转。将命令进行修改，执行成功。
正确命令如下：
[root@localhost install]# sudo rpm -ivh oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm --force --nodeps
warning: oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY

7、进行验证，如下为成功：
[root@localhost install]# id oracle
uid=65535(oracle) gid=65535(oinstall) groups=65535(oinstall),65541(racdba),65536(dba),65537(oper),65538(backupdba),65539(dgdba),65540(kmdba)
[root@localhost install]#
第一日学习结束。。。
