节点分发

#从任意Master节点分发配置到其他所有的节点(包括其他的Master与Node)
#本例中从master-1分发
[root@master-1 ~]# yum install -y expect
[root@master-1 ~]# ssh-keygen -t rsa -P "" -f /root/.ssh/id_rsa
#密码更换
[root@master-1 ~]# export mypass=123456
[root@master-1 ~]# name=(master-1 master-2 master-3 node-1 node-2)
[root@master-1 ~]# for i in ${name[@]};do
expect -c "
spawn ssh-copy-id -i /root/.ssh/id_rsa.pub root@$i
  expect {
    \"*yes/no*\" {send \"yes\r\"; exp_continue}
    \"*password*\" {send \"$mypass\r\"; exp_continue}
    \"*Password*\" {send \"$mypass\r\";}
