OL7.6上RPM方式安装Oracle 19c的教程

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

[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

[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

总结

以上所述是小编给大家介绍的ol7.6上rpm方式安装oracle 19c的教程,希望对大家有所帮助
