一、创建一个目录，用来存放脚本
[root@localhost scripts]# tree
.
├── host
└── ssh.sh
0 directories, 2 files
[root@localhost scripts]#
二、编写脚本
[root@localhost scripts]# cat ssh.sh
#!/bin/bash
set -e
yum -y install expect
if [ ! -f ~/.ssh/id_rsa ];then
ssh-keygen -t rsa -P "" -f ~/.ssh/id_rsa
else
echo "id_rsa already exist "
fi
while read line
do
user=`echo $line | cut -d " " -f 2`
ip=`echo $line | cut -d " " -f 1`
password=`echo $line | cut -d " " -f 3`
expect << EOF
set timeout 10
spawn ssh-copy-id $user@$ip
expect {
"yes/no" { send "yes\n";exp_continue }
"password" { send "$password\n" }
}
expect "password" { send "$password\n"}
EOF
done < host
[root@localhost scripts]# cat host
192.168.91.134 root 1 //本机IP 用户 密码
192.168.91.135 root 1 //对端IP 用户 密码
[root@localhost scripts]#
三、验证效果
[root@localhost opt]# bash -x ssh.sh
+ set -e
+ yum -y install expect
