我使用Perceus Cluster Software(http://perceus.org)为我们的群集进行了共享/家庭设置.节点使用的是CentOS 6.1 x86_64./ home由nfs(NFSv4)从头部共享到节点.
root@head~]$ cat /etc/exports
/var/lib/perceus/ 10.10.10.0/255.255.255.0(ro,no_root_squash,async)
/home/ 10.10.10.0/255.255.255.0(rw,no_root_squash,no_all_squash,async)
这是每个节点上的/ etc/fstab(都是相同的).
...
10.10.10.2:/var/lib/perceus/ /var/lib/perceus/ nfs ro,soft,bg 0 0
10.10.10.2:/home/ /home nfs rw,soft,bg 0 0
节点上的/ etc/fstab是头/主的副本,具有相同的UID:GID.
我使用以下方法创建了密钥对:
$ cd ~
$ rm -rf .ssh
$ mkdir .ssh
$ chmod 700 .ssh
$ ssh-keygen -t dsa -P ""
Generating public/private dsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_dsa):
Your identification has been saved in /home/user/.ssh/id_dsa.
Your public key has been saved …
