Linux下安装Oracle express

权且记录下来，以备以后查询
安装的是oracle-xe-univ-10.2.0.1-1.0.i386.rpm 软件包，可以从Oracle官网上下载（需要是注册用户才能下载）.

[root@localhost ~]# rpm -ivh oracle-xe-univ-10.2.0.1-1.0.i386.rpm
Preparing... ########################################### [100%]
   1:oracle-xe-univ ########################################### [100%]
Executing Post-install steps...
You must run '/etc/init.d/oracle-xe configure' AS the root user TO
configure the DATABASE.

安装完成之后提示需要配置，配置过程如下

[root@localhost ~]# /etc/init.d/oracle-xe configure

Oracle DATABASE 10g Express Edition Configuration
-------------------------------------------------

This will configure on-boot properties of Oracle DATABASE 10g 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]:8081

Specify a port that will be used FOR the DATABASE listener [1521]:

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:

Do you want Oracle DATABASE 10g Express Edition TO be started ON boot (y/n) [y]:y

Starting Oracle Net Listener...Done
Configuring DATABASE...Done
Starting Oracle DATABASE 10g Express Edition Instance...Done
Installation Completed Successfully.
TO access the DATABASE Home Page go TO ""

以上三处需要配置，分别是web端口，数据库监听端口和system用户密码.
安装完毕之后发现terminal中并没有sqlplus命令，修改环境变量如下

[root@localhost XE]# vim /etc/bashrc ＃在末尾增加如下语句export ORACLE_SID=XEexport ORACLE_OWNER=oracleexport ORACLE_HOME=/usr/lib/oracle/xe/app/oracle/product/10.2.0/serverexport PATH=$PATH:$ORACLE_HOME/bin:/sbin＃source一下生效[root@localhost XE]# source /etc/bashrc
