这篇文章主要介绍如何在云主机上安装 Oracle Database 19c，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
能不能在免费的 Oracle 云主机上安装最新的 Oracle Database 呢？
答案是肯定的。虽然免费的 Oracle 云主机配置低，只有 1OCPU,1GB 内存，但还是能成功把 19c 的数据库正常跑起来！
首先，我们需要将安装包上传到云主机：
这里我们使用了 rpm 包的安装方式，以方便安装。从这里可以看到上传的速率还可以，能达到 5MB/ s 了。
上传万 rpm 安装包后，就可以着手来安装数据库了！
先安装依赖包及设置必要的系统参数，我们可以使用 oracle-database-preinstall-19c 来简化该步骤：
[root@instance-20200526-2329 ~]# yum install oracle-database-preinstall-19c

[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-19c configure
Verifying : oracle-database-ee-19c-1.0-1.x86_64 1/1
Installed:
oracle-database-ee-19c.x86_64 0:1.0-1
Complete!这一步的安装需要花点时间，大约需要 20-30 分钟。
安装完成 Oracle Database 软件后，我们需要 tmpfs 的大小，因为系统默认的只有 486M，太小了：
[root@instance-20200526-2329 ~]# mount -o size=3072M -o remount /dev/shm
[root@instance-20200526-2329 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 458M 0 458M 0% /dev
tmpfs 3.0G 0 3.0G 0% /dev/shm
tmpfs 486M 31M 455M 7% /run
tmpfs 486M 0 486M 0% /sys/fs/cgroup
/dev/sda3 39G 13G 26G 33% /
/dev/sda1 200M 9.7M 191M 5% /boot/efi
tmpfs 98M 0 98M 0% /run/user/1001然后切换到 Oracle 用户，来创建数据库。注意：
/etc/init.d/oracledb_ORCLCDB-19c configure这里不建议使用，由于系统配置低，使用这个脚本来创建数据库会失败。所以需要手工来创建数据库。
使用 rpm 安装的 ORALCE_HOME 为 /opt/oracle/product/19c/dbhome_1
配置好参数文件：
db_name= ORCL
memory_target=768M
processes = 150
audit_file_dest= /opt/oracle/admin/orcl/adump
audit_trail = db
db_block_size=8192

open_cursors=300
remote_login_passwordfile= EXCLUSIVE
undo_tablespace= UNDOTBS1
control_files = (ora_control1, ora_control2)
compatible = 11.2.0启动并创建数据库：
