Oracle rac 基于 NFS存储的实现


oracle的安装规划方面不用多介绍了,只介绍NFS的配置和安装过程中的一些使用asm磁盘的不同点。

1、环境准备
2个rac节点,4台存储节点
计算节点:
10.160.36.64
10.160.36.76
存储节点:
10.160.36.33
10.160.36.60
10.160.36.62
10.160.36.70

2、NFS存储准备
nfs存储提供端安装nfs软件
yum install -y nfs-utils
yum install -y portmap

chkconfig nfs on
service rpcbind start
service nfs start

#lvcreate -L 7999G -n datalv1 -i 4 -I 64 datavg
lvcreate -n datalv11 -L 7990G datavg
mkfs.ext4 /dev/datavg/datalv1
mount /dev/datavg/datalv1 /oradata

vi /etc/fstab
/dev/datavg/datalv1    /oradata ext4 defaults 0 0
vi /etc/exports
每台存储分别设置
/oradata                 *(rw,sync,no_wdelay,insecure_locks,no_root_squash)

3、NFS客户端准备,也就是rac两个计算节点
计算节点:
/dev/vdb    /u01    ext4    defaults 0 0
10.160.36.33:/oradata /oradata1 nfs rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0
10.160.36.60:/oradata /oradata2 nfs rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0
10.160.36.63:/oradata /oradata3 nfs rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0
10.160.36.70:/oradata /oradata4 nfs rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 0 0

4、安装rac
注意ocr和votedisk 的文件路径和冗余的选择
