1.2台系统为Centos6.5的机器,其中 1台做nfs(硬盘大小至少4T)
2. 每台机器至少2块网卡
3. 准备5个可用的IP地址(一个为scan,二台配置各配置public和private地址)
4. 内存至少2G以下内存,建议使用4G或者更高
第一台主机:rac1 网卡eth0 IP地址:172.16.0.1/24 网卡eth2地址: 192.168.1.192/24
第一台主机:rac1 网卡eth0 IP地址:172.16.0.2/24 网卡eth2: 192.168.1.193/24
虚拟IP地址:192.168.1.200

$ ssh rac2 cat .ssh/id_dsa.pub >>.ssh/authorized_keys
$ scp.ssh/authorized_keys rac2:.ssh/authorized_keys
$ssh rac1 date
$ssh rac2 date
以上操作需要在二台机器都要操作
Rac1上使用fdisk /dev/sdb 分2个区sdb1、sdb2并进行格式化
#mkfs.ext3 /dev/sdb1
#mkfs.ext3 /dev/sdb2
rac1上创建共享目录
#mkdir -p /shared_config
#mkdir -p /shared_data
#vi /etc/fstab 添加以下:
/dev/sdb1 /shared_config ext3 defaults 0 0
/dev/sdb2 /shared_data ext3 defaults 0 0
#vi /etc/exports 设置共享
/shared_config *(rw,sync,no_wdelay,insecure_locks,no_root_squash)
/shared_data *(rw,sync,no_wdelay,insecure_locks,no_root_squash)
#chkconfig nfs on开启nfs服务
#service nfs restart
#vi /etc/fstab添加以下开机挂载共享目录
nas1:/shared_config /u01/shared_config nfs rw,bg,hard,nointr,noac,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0
nas1:/shared_data /u01/oradata nfs rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0
挂载相应的目录
#mount /u01/shared_config
#mount /u01/oradata
#chown grid:oinstall /u01/shared_config
#chown oracle:oinstall /u01/oradata
#chmod 775 /u01/oradata
#chmod 775 /u01/app/11.2.0/grid
unzip grid-XXX.zip
在root下输入xhost +
#su – grid
$cd grid-XXX
$./runcluvfy.sh stage-pre crsinst -n rac1,rac2 -fixup -verbose | tee check_grid.txt
如果最后提示:集群服务设置的预检查成功.可以开始去安装 grid 否则请查看失败在什么地方解决后再次执行该命令行来检查.
运行安装目录下的runInstaller
$./ runInstaller
