很简单，把rpm包转deb包，直接安装就好。如果内存不够的话，最好建立虚拟内存。

# 转换与安装

　1. 先安装 alien 和 fakeroot 这两个工具，其中前者可以将 rpm 包转换为 deb 包。安装命令为：

```

sudo apt-get install alien fakeroot

```

2. 将需要安装的 rpm 包下载备用，假设为 package.rpm。

3. 使用 alien 将 rpm 包转换为 deb 包：

```

fakeroot  alien  oracle-xe-11.2.0-1.0.x86_64

```

4. 一旦转换成功，我们可以即刻使用以下指令来安装：

```

sudo dpkg -i  oracle-xe_11.2.0-2_amd64.deb

```

安装似乎是一个简单的复制包的过程，没见有什么特别的提示。反正是没见报错。

5. 卸载服务

```

sudo dpkg -r packagesrv

```

# 配置

安装成功之后, 进行配置，执行`/etc/init.d/oracle-xe configure`

```bash

root@PC2020:/etc/init.d#  chmod u+x oracle-xe

root@PC2020:/etc/init.d# /etc/init.d/oracle-xe configure

Oracle Database 11g Express Edition Configuration

-------------------------------------------------

This will configure on-boot properties of Oracle Database 11g Express 

Edition.  The following questions will determine whether the database should 

be starting upon system boot, the ports it will use, and the passwords that 

will be used for database accounts.  Press to accept the defaults. 

Ctrl-C will abort.

Specify the HTTP port that will be used for Oracle Application Express [8080]:9090

Specify a port that will be used for the database listener [1521]:1520

Specify a password to be used for database accounts.  Note that the same

password will be used for SYS and SYSTEM.  Oracle recommends the use of 

different passwords for each database account.  This can be done after 

initial configuration:

Confirm the password:
