这篇文章主要介绍了OL7.6上RPM方式安装Oracle 19c的教程详解，非常不错，具有一定的参考借鉴价值,需要的朋友可以参考下
设置主机名
[root@localhost ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.0.0.11 study1.localdomain study1 [root@localhost ~]# cat /etc/hostname study1.localdomain
安装环境准备工具
其实直接rpm安装即可，它会自动解决依赖问题包括环境准备工具，但是这样oracle用户没有home目录，所以单独先安装环境准备工具
[root@study1 /]# yum -y install oracle-database-preinstall-19c Loaded plugins: langpacks, ulninfo ol7_UEKR5 | 2.5 kB 00:00:00 ol7_latest | 2.7 kB 00:00:00 (1/4): ol7_UEKR5/x86_64/updateinfo | 49 kB 00:00:01 (2/4): ol7_latest/x86_64/updateinfo | 1.1 MB 00:00:05 (3/4): ol7_UEKR5/x86_64/primary_db | 5.7 MB 00:00:27 (4/4): ol7_latest/x86_64/primary_db | 19 MB 00:01:21 Resolving Dependencies (many more lines supressed) Installed: oracle-database-preinstall-19c.x86_64 0:1.0-1.el7 Dependency Installed: compat-libcap1.x86_64 0:1.10-7.el7 compat-libstdc++-33.x86_64 0:3.2.3-72.el7 glibc-devel.x86_64 0:2.17-292.0.1.el7 glibc-headers.x86_64 0:2.17-292.0.1.el7 kernel-headers.x86_64 0:3.10.0-1062.el7 ksh.x86_64 0:20120801-139.0.1.el7 libaio-devel.x86_64 0:0.3.109-13.el7 libstdc++-devel.x86_64 0:4.8.5-39.0.1.el7 Dependency Updated: glibc.x86_64 0:2.17-292.0.1.el7 glibc-common.x86_64 0:2.17-292.0.1.el7 libstdc++.x86_64 0:4.8.5-39.0.1.el7 Complete! [root@study1 /]#
如果是rhel或者centos，就要手工先下载preinstall的rmp包，然后本地安装(或者添加oracle linux的yum源来yum安装)
[root@study1 /]# curl -o oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 18204 100 18204 0 0 18037 0 0:00:01 0:00:01 --:--:-- 18059 [root@study1 /]# yum -y localinstall oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
安装oracle软件
[root@study1 db]# yum -y localinstall oracle-database-ee-19c-1.0-1.x86_64.rpm Loaded plugins: langpacks, ulninfo Examining oracle-database-ee-19c-1.0-1.x86_64.rpm: oracle-database-ee-19c-1.0-1.x86_64 Marking oracle-database-ee-19c-1.0-1.x86_64.rpm to be installed Resolving Dependencies --> Running transaction check ---> Package oracle-database-ee-19c.x86_64 0:1.0-1 will be installed --> Finished Dependency Resolution Dependencies Resolved ======================================================================================================================================================================================================================== Package Arch Version Repository Size ======================================================================================================================================================================================================================== Installing: oracle-database-ee-19c x86_64 1.0-1 /oracle-database-ee-19c-1.0-1.x86_64 6.9 G Transaction Summary ======================================================================================================================================================================================================================== Install 1 Package Total size: 6.9 G Installed size: 6.9 G Downloading packages: Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : oracle-database-ee-19c-1.0-1.x86_64 1/1 [INFO] Executing post installation scripts...

[root@study1 db]# oracle_home目录是/opt/oracle/product/19c/dbhome_1
创建数据库
[root@study1 dbhome_1]# /etc/init.d/oracledb_ORCLCDB-19c configure Configuring Oracle Database ORCLCDB. Prepare for db operation 8% complete Copying database files 31% complete Creating and starting Oracle instance 32% complete 36% complete 40% complete 43% complete 46% complete Completing Database Creation 51% complete 54% complete Creating Pluggable Databases 58% complete 77% complete Executing Post Configuration Actions 100% complete Database creation complete. For details check the logfiles at: /opt/oracle/cfgtoollogs/dbca/ORCLCDB. Database Information: Global Database Name:ORCLCDB System Identifier(SID):ORCLCDB Look at the log file "/opt/oracle/cfgtoollogs/dbca/ORCLCDB/ORCLCDB.log" for further details. 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. [root@study1 dbhome_1]#
这默认创建了名为ORCLCDB且pdb名ORCLPDB1的数据库，当然可以不用这么创建，用传统的dbca方式
优缺点
实际上这个方式并没有什么用，比起来静默安装也并没有显得更容易，只能安装数据库软件，并不能升级数据库，而且不能用于rac，只能用于安装单实例数据库，整个部署没有给予定制空间比如oracle_home目录如果和你公司的磁盘规划不一致呢，不过新手可能认为这样更简单，这个方式仅试试而已体会一下，实际生产中几乎是不能用的
