Shell批量登陆和执行安全基线检查脚本

*本文原创作者:nothing100,

前言

由于没有相关自动化安全检查基线设备,为了方便自己工作,写了个shell脚本,批量登陆、执行、提取远程服务器数据。

脚本说明

1.将本目录所有文件都放入到一台自己的本地linux主机同一目录下

2.将服务器IP、普通账号、普通账号密码、root密码依次按以下格式写入到hosts.txt中(注意“~”作为hosts.txt的分隔符):

192.168.1.81~user~123456~nothing

192.168.1.10~user~123456~nothing

192.168.1.11~user~123456~nothing

3.执行sh login.sh,脚本将自动批量上传checklinux.sh到服务器/tmp目录下,并且自动执行和自动上传结果到本地linux主机上

4.最后将服务器上传的脚本和结果自动删除

(注意:本脚本适用于linux系统)

主脚本login.sh(用于批量调用put.exp、sh.exp、get.exp、del.exp无交互脚本)
