目录

之前下载centos8.2 来安装oracle12c 发现怎么都装不成功，最后发现
oracle官方Linux7 系列之支持oracle 最高版本到18c linux8系列 只有oracle 19c支持。故果断下载oracle linux 7.8（跟centos7.8安装类似 ）
安装oracle12c

脚本为一键静默安装，因为考虑到服务器不能联网的特点，连同必须的rpm包一起打包，真正做到了【一键静默离线安装oracle12c！】

安装前的准备

最小安装OracleLinux7.8（centos7.8一样）

（文末附下载）
安装详细过程不做介绍，一步一步即可
主要选择软件包的时候,选择基本的开发环境包和兼容包即可。

在这里插入图片描述

安装oracle需要的依赖包

这些依赖包下载后打包成oracle_pkg.tar 并放入/Data/soft文件夹下
本文已经将rmp打包完毕 直接下载即可使用。
oracle12c所需要的库文件下载

准备Oracle安装包

把Oracle12C原安装包"linuxx64_12201_database.zip" 放入 /Data/soft
这个linuxx64_12201_database.zip需要去oracle 官网下载即可
或者在网盘里下载
两个链接下载哪个都可以
下载链接1
下载链接2

准备一键安装脚本 并执行

一键安装脚本借鉴spdir大神的 https://github.com/spdir/oracle-single-install
并进行了修改，可以灵活自定义安装oracle的路径和源文件位置并支持不联网的情况下安装oracle12c

脚本使用安装前配置

root用户执行(尽量系统为纯净环境)

  1. 安装前请将Oracle 12C安装包放置在/Data/soft目录下,如果是其他目录修改脚本中的softdir变量
  2. 系统需要具备512MB的交换分区
  3. 并配置以下信息
    本机IP地址 HostIP 设置改成自己的IP
    脚本是通过
HostIP=`ip a | grep ens32 | grep inet |awk '{print $2}'|cut -d / -f 1`

注意上面的ens32 是自己电脑的网卡名称，如果是eth0 或者其他名字请更换为正确的网卡名称。

  • Oracle用户密码 OracleUserPasswd 默认为oracle
  • Oracle数据库管理员密码 ORACLE_DB_PASSWD 默认为 Oracle#123
  • Oracle SID/ServerName SID 默认为 orcl12c
  • 是否安装实例 IS_INSTANCE
    • 0-不安装实例
    • 1-安装单实例（默认）
    • 2-安装cdb : 因为CDB在初始化过程中需要输入参数，需要手动初始化,具体步骤会在最后进行提示
  • 设置单实例默认字符编码SINGLE_CHARSET
    • 1-AL32UTF8
    • 2-ZHS16GBK默认
  • 选择配置静默安装配置文件的获取方式Get_Config_Method
    • 0-远程
    • 2-本地获取(默认)(脚本执行根目录下需要有conf目录存放配置文件)
      • db_install.rsp 数据库安装配置文件
      • dbca_single.rsp 数据库单实例初始化配置文件
      • initcdb.ora CDB初始化配置文件

上面文件如果都下载好
服务器/Data/soft 目录完整文件应该为
在这里插入图片描述

cd /Data/soft
tar xvf oracleLinux7_install_oracle12c.tar
chmod +x oracleLinux7_install_oracle12c.sh
sh oracleLinux7_install_oracle12c.sh

脚本默认安装目录/Data

oracle安装包位置 /Data/soft

如果修改请修改 datadir和softdir的变量值。

脚本提示输入oracle 用户密码 默认Oracle#123

脚本提示输入SID 默认 orcl12c

本脚本在oracle linux 7.8 上验证通过。

附：

oracle Linux 7.8 下载地址：

oracle Linux 7.8 下载地址

问题及解决方法：

PLSQL无法链接的错误：

错误码ORA-28040

修改 $ORACLE_HOME\NETWORK\ADMIN\sqlnet.ora 文件，网上提供了两种版本的修改：

a、增加一行配置如下

SQLNET.ALLOWED_LOGON_VERSION=8

b、增加两行配置如下“

SQLNET.ALLOWED_LOGON_SERVER=8

SQLNET.ALLOWED_LOGON_CLIENT=8

错误码ORA-01017

#在 错误码ORA-28040之前创建的用户需要修改密码
sqlplus / as sysdba
alter user dbuserbasic identified by 123456;
