RAC：Oracle19C数据库一键安装

本文将演示如何使用脚本一键安装 Oracle 19C RAC 3 节点数据库的全过程。

在生产环境中&＃xff0c;Linux 操作系统和网络一般不是由 DBA 来配置&＃xff0c;为了更贴合生产使用&＃xff0c;本脚本仅用于安装 Oracle 数据库&＃xff0c;请提前安装好 Linux 操作系统。

在执行脚本之前&＃xff0c;必须提前配置好 Public 和 Private 地址。

在执行脚本之前&＃xff0c;必须提前挂载好共享存储&＃xff0c;脚本会自动配置多路径和udev。

首先&＃xff0c;使用 ssh 工具连接到节点一 Linux 主机&＃xff0c;创建一个存放安装介质的目录&＃xff0c;比如&＃xff1a;mkdir /soft&＃xff0c;然后上传安装所需的介质&＃xff01;

&＃x1f4e2; 注意&＃xff1a;

• 1、安装介质只需要在节点一上传&＃xff0c;节点二无需上传任何介质&＃xff1b;

[root&＃64;luciferdb03:/soft]# du -sh *
11G CentOS-7-x86_64-Athena-1904.iso ## 操作系统镜像
2.9G LINUX.X64_193000_db_home.zip ## 19C Grid 安装包
2.7G LINUX.X64_193000_grid_home.zip ## 19C Database 安装包
160K OracleShellInstall ## 一键安装脚本
2.5G p33509923_190000_Linux-x86-64.zip ## 19C Grid PSU 补丁
120M p33808367_190000_Linux-x86-64.zip ## 19C DB OJVM 补丁
119M p6880880_190000_Linux-x86-64.zip ## 19C OPatch 补丁
276K rlwrap-0.42.tar.gz ## 优化 sqlplus、rman 的翻页小插件


上传好以上安装介质就完成了第一步☝。

安装 Oracle 数据库需要安装一些 rpm 的依赖包&＃xff0c;需要使用 yum 命令来安装&＃xff0c;这就需要挂载 ISO 镜像来配置本地 YUM 源&＃xff1a;

mount -o loop /soft/CentOS-7-x86_64-Athena-1904.iso /mnt


这里只需要执行 mount 命令挂载到 /mnt 目录下即可&＃xff0c;配置好本地 YUM 源后&＃xff0c;脚本里会自动配置 repo&＃xff0c;执行 df -h | grep mnt 看到如下输出即代表成功挂载&＃xff1a;

[root&＃64;orcl soft]# df -h | grep mnt
/dev/loop0 11G 11G 0 100% /mnt


&＃x1f4e2; 注意&＃xff1a;如果不挂载 ISO 执行脚本&＃xff0c;会提示&＃xff1a;The iso file is not mounted on system&＃xff01;
