boot.sh：配置SSH遠程免密登錄挨决，并將install.sh拷貝到遠程主機執(zhí)行
#!/bin/bash
SERVERS="mini3"
PASSWORD=huachao
BASE_SERVER=mini
auto_ssh_copy_id() {
expect -c "set timeout -1;
spawn ssh-copy-id $1;
expect {
*(yes/no)* {send -- yes\r;exp_continue;}

install.sh：下載解壓jdk-7u45-linux-x64.tar.gz掸绞，并配置java環(huán)境變量
#!/bin/bash
BASE_SERVER=mini1
yum install -y wget
wget $BASE_SERVER/soft/jdk-7u45-linux-x64.tar.gz
tar -zxvf jdk-7u45-linux-x64.tar.gz -C /usr/local
cat >> /etc/profile << EOF
export JAVA_HOME=/usr/local/jdk1.7.0_45
export PATH=\$PATH:\$JAVA_HOME/bin

執(zhí)行上面腳本的環(huán)境和條件
在主機和每一臺從機上安裝expectyum -y install expect
在主機和每一臺從機上安裝ssh_client(scp命令依賴ssh客戶端)yum -y install openssh-clients.x86_64
在主機上要先生成ssh的keyssh-keygen
問題
問題1：expect:command not foundyum -y install expect
問題2： WARNING: POSSIBLE DNS SPOOFING DETECTED!ssh-copy-id對要遠程連接的主機腐碱，現(xiàn)在該主機的IP發(fā)生了變化vi /root/.ssh/known_hosts, 刪除掉那個主機對應(yīng)的公鑰梯啤，保存退出再連接就可以了
問題3：spawn ssh-copy-id mini1/usr/bin/ssh-copy-id: ERROR: No identities foundssh-keygen
