10、安装cluster集群软件
上传集群软件包：10201_clusterware_linux_x86_64.cpio.gz [oracle@rac1 ~]$ ls
10201_clusterware_linux_x86_64.cpio.gz app 解压
[oracle@rac1 ~]$ gunzip 10201_clusterware_linux_x86_64.cpio.gz [oracle@rac1 ~]$ cpio -idmv < 10201_clusterware_linux_x86_64.cpio [oracle@rac1 ~]$ ls
10201_clusterware_linux_x86_64.cpio app clusterware
赋予clusterware目录执行的权限，执行安装程序runinstaller，使用Xwin-32起图形。 [oracle@rac1 ~]$ chmod +x -R clusterware/ [oracle@rac1 ~]$ cd clusterware/
[oracle@rac1 clusterware]$ export DISPLAY=192.168.10.6:0.0 [oracle@rac1 clusterware]$ ./runInstaller

Please run the script rootpre.sh as root on all machines/nodes. The script can be found at the toplevel of the CD or stage-area. Once you have run the script, please type Y to proceed
Answer 'y' if root has run 'rootpre.sh' so you can proceed with Oracle Clusterware installation. Answer 'n' to abort installation and then ask root to run 'rootpre.sh'.
********************************************************************************
Has 'rootpre.sh' been run by root? [y/n] (n) Y
