先建好hosts.txt文件

# 格式: ip地址 root密码
python@ubuntu20:/server/scripts/paramiko$ cat hosts.txt

10.0.0.41 123456
10.0.0.51 123456
10.0.0.7 123456

先执行添加随机密码脚本, 生成新文件 newhosts.txt

python@ubuntu20:/server/scripts/paramiko$ python3 add_random_pwd.py ./hosts.txt
10.0.0.202 123456 *#RtV$Ua4Gj83CKW

python@ubuntu20:/server/scripts/paramiko$ cat newhosts.txt
10.0.0.202 123456 *#RtV$Ua4Gj83CKW

10.0.0.51 123456 Y34KGk4*KzD0XfLg
10.0.0.7 123456 ESrRxDO&asvv#Aub

执行修改密码脚本

# 为了之后虚拟机方便还原密码,手动修改了一下newhosts.txt做测试,只修改一台机器
python@ubuntu20:/server/scripts/paramiko$ cat newhosts.txt
10.0.0.41 123456 centos

python@ubuntu20:/server/scripts/paramiko$ python3 modify_server_pwd.py ./newhosts.txt
