設定時間同步 crontab -e

dev/shm 共享內存不足
解决方法：
例如：为了将/dev/shm的大小增加到1GB，修改/etc/fstab的这行：默认的：
none     /dev/shm       tmpfs   defaults        0 0
改成：
none     /dev/shm       tmpfs   defaults,size=1024m        0 0
size参数也可以用G作单位：size＝1G。
重新mount /dev/shm使之生效：
# mount -o remount /dev/shm
或者：
# umount /dev/shm
# mount -a
马上可以用"df -h"命令检查变化。

配置對等性關係

在node1，node2上執行
mkdir ~/.ssh
chmod 700 ~/.ssh

ssh-keygen -t rsa
ssh-keygen -t dsa

在node1上執行
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

ssh node2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
ssh node2 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
scp ~/.ssh/authorized_keys node2:~/.ssh/authorized_keys
