篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Oracle 8c数据库最新安装模式相关的知识，希望对你有一定的参考价值。
Oracle史上首次推出的第一个数据库rpm安装包。通过rpm包安装Oracle 18c更简单方便，省去通过vnc等图形化或静默方式安装的繁琐步骤。总之，oracle越来越方便，更加人性化；如下所安装过程。
看oracle 18c安装包的信息

[root@localhost mnt]#

注意：如果要通过rpm包安装oracle 18c数据库，需要预安装oracle-database-preinstall-18c
安装18c rpm安装包
[root@localhost mnt]# id oracle uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54322(dba),54324(oper),54325(backupdba),54326(dgdba),54327(kmdba),54330(racdba) [root@localhost mnt]# rpm -ivh oracle-database-ee-18c-1.0-1.x86_64.rpm Preparing... ########################################### [100%] 1:oracle-database-ee-18c ########################################### [100%] [INFO] Executing post installation scripts... [INFO] Oracle home installed successfully and ready to be configured. To configure a sample Oracle Database you can execute the following service configuration script as root: /etc/init.d/oracledb_ORCLCDB-18c configure [root@localhost mnt]#
查看18c sample配置文件内容
[root@localhost ~]# cat /etc/sysconfig/oracledb_ORCLCDB-18c.conf #This is a configuration file to setup the Oracle Database. #It is used when running '/etc/init.d/oracledb_ORCLCDB configure'. #Please use this file to modify the default listener port and the #Oracle data location. # LISTENER_PORT: Database listener LISTENER_PORT=1521 # ORACLE_DATA_LOCATION: Database oradata location ORACLE_DATA_LOCATION=/opt/oracle/oradata # EM_EXPRESS_PORT: Oracle EM Express listener EM_EXPRESS_PORT=5500 [root@localhost ~]#

Database configuration completed successfully. The passwords were auto generated, you must change them by connecting to the database using 'sqlplus / as sysdba' as the oracle user.

通过下面的图片我们能看到，后台实际上还是通过静默方式安装的。
