以前安装总结的，现把它贴出来，虽然10g现在慢慢越少了，但也有不少生产库跑10g的。

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
ssh orcldb2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
ssh orcldb2 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
scp ~/.ssh/authorized_keys orcldb2:~/.ssh/authorized_keys
两机相互执行，看看是否还需要输入密码
ssh orcldb1 date
ssh orcldb2 date
ssh orcldb1-priv date
ssh orcldb2-priv date
住：创建oracle用户尽量别-d 指定路径。要不权限问题ssh怎么都不通。
切换至node2 执行
ssh orcldb1 date
ssh orcldb2 date
ssh orcldb1-priv date
ssh orcldb2-priv date
安装集群软件
./runInstaller -ignoreSysPrereqs
接着图形化界面略过，到最后执行root.sh之前安装补丁p4679769，linux 下使用多路径时，需要安装该补丁。
clsfmt.bin这个文件覆盖到两个节点$CRS_HOME/bin下
执行./clsfmt ocr /dev/raw/raw1 测试
具体也可参考http://blog.csdn.net/tianlesoft/article/details/6039210
执行root.sh之前两个节点修改vipca和srvctl
if [ "$arch" = "i686" -o "$arch" = "ia64" ]
then
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
fi
#End workaround
在fi 后新添加一行：
unset LD_ASSUME_KERNEL
找到如下内容：
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
同样在其后新增加一行：
unset LD_ASSUME_KERNEL
CSS is active on all nodes.
