UOS服务器版1050E安装ORACLE19C

1.拷贝rpm文件

oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

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

2.安装环境所需

compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm

compat-libcap1-1.10-7.el7.x86_64.rpm

2.1如果yum仓库不含阿里云则需要手工修改

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

在打开配置文件

sudo vi /etc/yum.repos.d/CentOS-Base.repo

将文件中所有行的 $releasever 改为 7

:1,$s/$releasever/7/g

:wq

保存并退出

2.2安装环境包

sudo yum install compat-libstdc*

sudo yum install compat-libcap1*

还需要安装

sudo yum install ksh* -y

sudo yum install libnsl* -y

sudo yum install file -y

sudo yum install file-libs* -y

sudo yum install net-tools -y

3.修改当前yum中引用python版本-确保在python3

查看当前python版本号

python -V

sudo vi /usr/bin/yum

把第一行改为

#! /usr/bin/python3

4.预安装

sudo rpm -ivh oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm --nodeps

5.创建所需文件夹 并授权

sudo mkdir -p /opt/oracle/product/19c/dbhome_1

sudo mkdir -p /opt/app/oracle/oradata

sudo mkdir -p /opt/oracle/oraInventory

sudo chown -R oracle:oinstall /opt/oracle

sudo chmod -R 775 /opt/oracle

6.开始安装

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

7.初始化配置(比较漫长的等待)

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

注意接下来的操作需要切换到oralce账户

8.启动

切换以oracle身份，启动侦听服务

su - oracle

配置环境变量

vi ~/.bash_profile

export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1

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

export ORACLE_SID=ORCLCDB

export NLS_LANG="AMERICAN_AMERICA.UTF8"

保存之后

source ~/.bash_profile

9.以dba身份登入sqlplus，并启动服务

sqlplus / as sysdba

startup

设置system账户密码

alter user system identified by "test123@6";

10.防火墙firewalld添加端口

开放oracle端口1521

firewall-cmd --zone=public --add-port=1521/tcp --permanent

重载firewalld

firewall-cmd --reload
