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

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
