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。
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）

*************************************************************************************
*****使用说明： **
***** 1.由于安全方面root可能无法远程登陆，所以本程序是先登陆普通用户在su到root用户
最后使用root执行login.sh脚本实现无交互批量登陆 **
***** 2.使用普通用户上传须可对/tmp目录读写执行权限 **
***** 3.远程服务器执行检查脚本和输出结果都在/tmp目录下面 **
***** 4.远程服务器执行完脚本后将会上传到本地/tmp目录下 **
***** 5.远程服务器将会自动删除checklinux.sh和输出结果 **
