通过rpm离线安装Oracle 19C

首先配置离线yum源

由于无法联网，因此需要配置本地yum源，才能使用yum安装配置方法见链接CentOS 7 配置本地 YUM源

下载需要的安装包

preinstall

wget http://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

Oracle 的rpm 安装包

https://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html

安装

安装后默认有oracle用户

yum localinstall -y oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
yum localinstall oracle-database-ee-19c-1.0-1.x86_64.rpm

安装结果如下：

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

配置

使用root用户编辑以下文件/etc/init.d/oracledb_ORCLCDB-19c修改内容如下：
以下是我修改的内容（只修改了sid和字符集，其他未做修改）

export ORACLE_SID=test
export CHARSET=ZHS16GBK

对应的要复制一参数文件

cd /etc/sysconfig/
 cp oracledb_ORCLCDB-19c.conf oracledb_test-19c.conf

运行配置命令

/etc/init.d/oracledb_ORCLCDB-19c configure

等待Oracle数据库执行初始化操作即可

/etc/init.d/oracledb_ORCLCDB-19c configure

修改oracle用户环境变量

切换oracle用户，增加环境变量处理，编辑.bash_profile

export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1
export PATH=$PATH:/opt/oracle/product/19c/dbhome_1/bin
export ORACLE_SID=ORA19C

NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"; export NLS_DATE_FORMAT
NLS_LANG=american_america.ZHS16GBK; export NLS_LANG

使环境变量生效

source .bash_profile

使用Oracle登录进行相关的处理

sqlplus / as sysdba

查看pdb信息

show pdbs

创建自动启动pdb的触发器(不设置PDB的开机启动 很多程序无法连接上PDB, 建议使用show pdbs 查看状态, 手工启动也可以. 不能在CDB创建业务数据, 会提示创建的用户名不符合 c###的要求)

REATE TRIGGER open_all_pdbs
   AFTER STARTUP ON DATABASE
BEGIN
   EXECUTE IMMEDIATE 'alter pluggable database all open';
END open_all_pdbs;
/

重启linux服务器. 然后可以工具连接尝试连接该数据库.
