1，下载oracle11g11.2.0.4.0安装包，解压

2，配置安装环境

1，下载配置环境文件-------------------------------------------------------------------------------------------------------------------------------------cd /etc/yum.repos.d  wget http://public-yum.oracle.com/public-yum-ol7.repo   wget http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol7 -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracleyum install oracle-rdbms-server-11gR2-preinstall -y  ##安装Oracle环境配置程序，安装后环境自动配置

2，配置用户环境变量-------------------------------------------------------------------------------------------------------------------------------------cat >>  /home/oracle/.bash_profile   <<  EOF   #添加oracle用户的环境变量export ORACLE_BASE=/opt/oracleexport ORACLE_HOME=/opt/oracle/product/11.2.0/db_1export ORACLE_SID=orclexport PATH=$ORACLE_HOME/bin:/usr/sbin:$PATHexport LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/libexport TNS_ADMIN=$ORACLE_HOME/network/adminEOF3，修改配置文件-------------------------------------------------------------------------------------------------------------------------------------修改解压后database目录下的 dbca.rsp db_install.rsp 这两个文件[root@yktmbsvcpt opt]# cd database/[root@yktmbsvcpt database]# lsinstall readme.html response rpm runInstaller sshsetup stage welcome.html[root@yktmbsvcpt database]# cd response/[root@yktmbsvcpt response]# lsdbca.rsp db_install.rsp netca.rsp

#################################################dbca.rsp 文件需要修改的地方GDBNAME = "orcl"SID = "orcl"CHARACTERSET = "ZHS16GBK"NATIONALCHARACTERSET= "UTF8"

#################################################

4，创建目录赋予权限-------------------------------------------------------------------------------------------------------------------------------------

(资料图)

mkdir /opt/oraclechown oracle:oinstall -R /opt/oraclechown oracle:oinstall -R database ##oracle解压后的目录

chmod 755 -R /opt/oracle

chmod 755 -R database

5，执行脚本，安装数据库程序-------------------------------------------------------------------------------------------------------------------------------------

su - oracle #切换用户

cd database

./runInstaller -silent -force -ignorePrereq -responseFile /opt/database/response/db_install.rsp

##执行后出现

Oracle Database 11g 的 安装 已成功。请查看 "/opt/oracle/oraInventory/logs/silentInstall2023-05-05_10-46-59AM.log" 以获取详细资料。以 root 用户的身份执行以下脚本: 1. /opt/oracle/oraInventory/orainstRoot.sh 2. /opt/oracle/product/11.2.0/db_1/root.shSuccessfully Setup Software.###以上文字，表示安装成功，然后切换root用户执行脚本

###以 root 用户的身份执行以下脚本:

su - root sh /opt/oracle/oraInventory/orainstRoot.shsh /opt/oracle/product/11.2.0/db_1/root.sh

6，执行脚本，安装监听程序-------------------------------------------------------------------------------------------------------------------------------------

su - oracle

netca /silent /responseFile /opt/database/response/netca.rsp

7，执行脚本，安装数据库-------------------------------------------------------------------------------------------------------------------------------------

dbca -silent -responseFile /opt/database/response/dbca.rsp ##执行后需要输入密码，输入配置文件密码即可

到此完成安装，开放防火墙，远程数据库即可。。。。
