1、把各个服务服务器的ip 用户名，用户密码，写入如下文件中

vim hostname.txt

47.100.47.180 root  ZHj1203110904!47.102.201.136 root  55555

 

2、运行下面的localtoremote.sh脚本。hostname.txt文件中的每一行，继而把公钥添加

vim localtoremote.sh

#!/bin/bash #by zhangjia#2019.07.29add_pub() {    yum install -y sshpass    [ -f ~/.ssh/id_rsa ] || ssh-keygen -t rsa -f ~/.ssh/id_rsa -P '' &> /dev/null    cat hostname | while read ips users pwds; do    sshpass -p $pwds ssh-copy-id -i ~/.ssh/id_rsa.pub ${users}@$ips -o StrictHostKeyChecking=no    done}del_pub() {    ansible all -u root  -m lineinfile -a "path=/root/.ssh/authorized_keys regexp=\"zhj5551@zhj5551$\" state=absent"}#add_p
