#修改/usr/bin/yum
#!/usr/bin/python-->#!/usr/bin/python2.6
#建立python2.7软链接

ln -s /usr/local/bin/python2.7 /usr/bin/python

ssh-key-geg -t rsa -P ''
#任意一台机子
cp /root/.ssh/id_rsa.pub /root/.ssh/authorized_keys
chmod 600 /root/.ssh/authorized_keys
#将其他机子的id_rsa.pub追加到authorized_keys，然后再将该文件传送到/root/.ssh/
scp /root/.ssh/authorized_keys root@ip:/root/.ssh/
#修改/etc/ssh/sshd_config，取消以下注释并重启sshd服务
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
#更改所有主机/etc/hosts
#设置完成后效果
#设置完成后效果，master、node1、node2、node3可以相互ssh免密码登录
