批量分发公钥脚本


使用脚本的方式批量分发公钥信息!

一、定义需要管理的主机

[root@localhost ~]# cat ip.txt 
192.168.1.2 root 123.com
192.168.1.3 root 123456

二、编写批量分发公钥的脚本

[root@localhost ~]# cat auto_ssh.sh 
#!/usr/bin/env bash
set -e
[ -f /root/.ssh/id_rsa ] || ssh-keygen -t rsa -f /root/.ssh/id_rsa -P "" &>/dev/null

[ -f /usr/bin/sshpass ] || yum -y install sshpass &> /dev/null

while read line
do
    ip=`echo $line | cut -d  " " -f1`
    user_name=`echo $line | cut -d  " " -f2`
    pass_word=`echo $line | cut -d  " " -f3`
echo "=============host $ip  pub-key start fenfa============="
    sshpass -p ${pass_word} ssh-copy-id -i /root/.ssh/id_rsa.pub ${user_name}@${ip} -o "StrictHostKeyChecking=no"  &> /dev/null
echo "host $ip fenfa success."
echo "=============host $ip  pub-key fenfa end============="
echo ""
done < /root/ip.txt
