以下环境使用云服务器 CentOS 7.6 ,4C8G进行安装配置

参考文档

https://docs.oracle.com/en/database/oracle/oracle-database/19/ladbi/operating-system-checklist-for-oracle-database-installation-on-linux.html#GUID-E5C0A90E-7750-45D9-A8BC-C7319ED934F0

一、下载安装介质

访问 https://edelivery.oracle.com/并获取下载地址

同意许可后

将wget.sh放到服务器上，并将

$WGET  --secure-protocol=auto --save-cookies="$COOKIE_FILE" --keep-session-cookies --http-user "$SSO_USERNAME" --ask-password  "https://edelivery.oracle.com/osdc/cliauth" -O /dev/null 2>> "$LOGFILE"

修改为

$WGET  --secure-protocol=auto --save-cookies="$COOKIE_FILE" --keep-session-cookies --http-user "$SSO_USERNAME" --ask-password  "https://edelivery.oracle.com/osdc/cliauth"

否则会有错误。

二、安装oracle-database-preinstall-19c

参考文档

https://docs.oracle.com/en/database/oracle/oracle-database/19/ladbi/installing-oracle-linux-with-public-yum-repository-support.html

三、配置环境准备安装

1、Oracle目录

mkdir -p /u01/app/oraInventory
mkdir -p /u01/app/oracle/product/19.3.0/dbhome_1
chown -R oracle:oinstall /u01/app/oracle
#解压
unzip -q V982063-01.zip -d /u01/app/oracle/product/19.3.0/dbhome_1

2、修改用户环境变量

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/19.3.0/dbhome_1
export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib

3、swap分区

dd if=/dev/zero of=/root/swapfile bs=1M count=8192
mkswap /root/swapfile 
swapon /root/swapfile 

#添加开机自动挂载
vim /etc/fstab 
/root/swapfile  swap    swap    defaults        0 0

4、修改响应文件

vim /u01/app/oracle/product/19.3.0/dbhome_1/install/response/db_install.rsp
oracle.install.option=INSTALL_DB_SWONLY 
UNIX_GROUP_NAME=oinstall 
INVENTORY_LOCATION=/u01/app/oraInventory 
ORACLE_HOME=/u01/app/oracle/product/19.3.0/dbhome_1
ORACLE_BASE=/u01/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.OSDBA_GROUP=dba
oracle.install.db.OSBACKUPDBA_GROUP=dba
oracle.install.db.OSDGDBA_GROUP=dba
oracle.install.db.OSKMDBA_GROUP=dba
oracle.install.db.OSRACDBA_GROUP=dba

5、安装

./runInstaller -ignorePrereq -waitforcompletion -silent  -responseFile  /u01/app/oracle/product/19.3.0/dbhome_1/install/response/db_install.rsp
