##### 批量部署ssh私钥认证 #####
一、首先安装expect,直接yum即可
二、批量部署ssh私钥脚本
batch_sshkey.sh
============================================================== #!/bin/bash cd /root cat /root/.ssh/id_rsa.pub > /root/.ssh/authorized_keys for i in `cat ip.txt`
do
ip=$(echo "$i"|cut -f1 -d":")
password=$(echo "$i"|cut -f2 -d":")
expect -c "
spawn scp /root/.ssh/authorized_keys /root/remote_operate.sh root@$ip:/tmp/
expect {
\"*yes/no*\" {send \"yes\r\"; exp_continue}
\"*password*\" {send \"$password\r\"; exp_continue}
\"*Password*\" {send \"$password\r\";}
}
" expect -c "
spawn ssh root@$ip "/tmp/remote_operate.sh"
expect {
\"*yes/no*\" {send \"yes\r\"; exp_continue}
\"*password*\" {send \"$password\r\"; exp_continue}
\"*Password*\" {send \"$password\r\";}
}
" done ============================================================ ip.txt(前面是IP,后面是密码,用冒号:分割) 192.168.8.23:123456
192.168.8.24:456789 ============================================================ remote_operate.sh #!/bin/bash if [ ! -d /root/.ssh ];then
mkdir /root/.ssh
fi
cp /tmp/authorized_keys /root/.ssh/
========================================================== 运行batch_sshkey.sh即可。
