Oracle 10g官方文档上写对于红帽linux只能装在rhel4以下的操作系统版本上，当然装在rhel5上也没有什么问题，但需要oracle公司的特别授权，否则将来无法联系oracle公司进行support。在rhel6上装oracle，如果采用传统的./runInstall.sh方式，则会遇到错误，需要用点特殊的手段，才能搞定！而且需要使用tar打包在rhel5上装好的oracle软件（关闭oracle后打包），软件体系架构要相符合；同样可以使用这种方式在PXE装机的时候，直接把oracle软件和数据库一起装上，但需要精心编写PXE post%节脚本！
1：创建oracle用户和oinstall,dba组
[root@rhel6 ~]# groupadd oinstall
[root@rhel6 ~]# groupadd dba
[root@rhel6 ~]# useradd -g oinstall -G dba oracle
[root@rhel6 ~]# echo 'oracle' |passwd --stdin oracle
Changing password for user oracle.
passwd: all authentication tokens updated successfully.
2：修改相应的环境变量
[root@rhel6 /]# su - oracle
[oracle@rhel6 ~]$ cat .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
ORACLE_BASE=/u01/app
ORACLE_HOME=/u01/app/oracle
ORACLE_SID=ora10g
LD_LIBRARY_PATH=$ORACLE_HOME/lib
PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
alias sqlplus='/usr/local/rlwrap/bin/rlwrap sqlplus'
alias rman='/usr/local/rlwrap/bin/rlwrap rman'
NLS_DATE_FORMAT='YYYY-MM-DD HH24:MI:SS'
NLS_LANG=american_america.UTF8
EDITOR=vim
export PATH ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH DISPLAY NLS_DATE_FORMAT NLS_LANG EDITOR
3：将rhel5上打包过的oracle解压到rhel6上
[root@rhel6 ~]# chown -R oracle.oinstall /u01/
[root@rhel6 /]# tar -zxvpf /u01/ora10g.tar.gz
4: 启动数据库报错如下，需要将oracle用户加入root组
[root@rhel6 /]# su - oracle
[oracle@rhel6 ~]$ sqlplus /nolog

5：启动isqlplus和listener
[oracle@rhel6 ~]$ lsnrctl start
[oracle@rhel6 ~]$ isqlplusctl start
[oracle@rhel6 ~]$ netstat -ntpl |egrep '1521|5560'
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)

6：重新配置dbconsole,配置前保证在rhel6上可以打开dbca和netca图形界面
