12c和11g环境是一样的，请参考前面
一、设置环境变量
vim /home/oracle/.bashrc ORACLE_BASE=/data/app/oracle ORACLE_HOME=$ORACLE_BASE/product/12.2.0 ORACLE_SID=orcl PATH=$PATH:$ORACLE_HOME/bin export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH source /home/oracle/.bashrc
二、设置hosts中添加主机名
vim /etc/hosts 127.0.0.1 xiaoyuer#自己的主机名 #当时我报了一个这样的错： ACTION: Ensure that the current user has required permissions to access the temporary location. mkdir -p /var/tmp/.oracle mkdir -p /tmp/.oracle 有两个文件 要给777的权限 chown -R oracle:oinstall /tmp/.oracle chown -R oracle:oinstall /var/tmp/.oracle
三、设置应答文件 db_install.rsp
vim /data/database/response/db_install.rsp #ORACLE_HOSTNAM #主机名 oracle.install.option=INSTALL_DB_SWONLY ORACLE_HOSTNAME=xiaoyuer UNIX_GROUP_NAME=oinstall INVENTORY_LOCATION=/data/app/oracle/inventory SELECTED_LANGUAGES=en,zh_CN ORACLE_HOME=/data/app/oracle/product/12.2.0 ORACLE_BASE=/data/app/oracle oracle.install.db.InstallEdition=EE oracle.install.db.OSDBA_GROUP=dba oracle.install.db.OSOPER_GROUP=oper oracle.install.db.OSBACKUPDBA_GROUP=dba oracle.install.db.OSDGDBA_GROUP=dba oracle.install.db.OSKMDBA_GROUP=dba oracle.install.db.OSRACDBA_GROUP=dba oracle.install.db.config.starterdb.type=GENERAL_PURPOSE oracle.install.db.config.starterdb.globalDBName=cdb1 oracle.install.db.config.starterdb.SID=cdb1 oracle.install.db.config.starterdb.characterSet=AL32UTF8 SECURITY_UPDATES_VIA_MYORACLESUPPORT=false DECLINE_SECURITY_UPDATES=true
启动： ./runInstaller -silent -ignorePrereq -ignoreSysPrereqs -responseFile /data/database/response/db_install.rsp
As a root user, execute the following script(s): 1. /data/app/oracle/inventory/orainstRoot.sh 2. /data/app/oracle/product/12.2.0/root.sh 出现这两个说明安装完成；会提示log文件可以监听；在root下执行
四、生成监听文件
#设置DISPLAY变量
export DISPLAY=localhost:0.0
netca -silent -responseFile /data/database/response/netca.rsp
Oracle Net Listener Startup:
Running Listener Control:
/data/app/oracle/product/12.2.0/bin/lsnrctl start LISTENER
Listener Control complete.
Listener started successfully.
Listener configuration complete.
Oracle Net Services configuration successful. The exit code is 0
查看监听状态：stop start
lsnrctl status
netstat -lntup|grep 1521
tcp 0 0 0.0.0.0:1521 0.0.0.0:* LISTEN 28351/tnslsnr
修改端口不对修改（不知道为什么我启动端口不是1521，修改这个文件重启静态就好了）
/data/app/oracle/product/12.2.0/network/admin/listener.ora
五、dbca生成数据库
[oracle@xiaoyuer response]$ cat dbca.rsp|grep -Ev '^#|^$'
