通过shell脚本实现批量更改密码

如果要调用mkpasswd就得安装expect,使用mkpasswd可以随机产生密码

usage: mkpasswd [args] [user]

where arguments are:

-l # (length of password, default = 10)

-d # (min # of digits, default = 2)

#!/bin/bash
#============== Though ssh remote server ,auto modify ROOT passwd =============#
for IP in `cat /bak/scripts/ip_list.txt` #导入远程要修改主机的IP
do

#========================= 创建远程主机密码 ===================================#
echo "megVjmbpo8tw2zn$nmcgguensluxayCw" > R_PWD.txt # 可以写成自己需要的密码
R_PWD=`cat R_PWD.txt` # 引用变量

#========================= 修改远程主机密码 ===================================#
if [ $? = 0 ] ; then
ssh $IP passwd root --stdin < R_PWD.txt
echo -e "$(date " %Y-%m-%d %H:%M:%S")t${IP}t${R_PWD}t" >> /var/log/R_Server.log
else
echo -e "$(date " %Y-%m-%d %H:%M:%S")t${IP} R_PWD.txt is create failtplease check!t" >> /var/log/M_pass.log
fi
if [ $? = 0 ] ; then
echo -e "$(date " %Y-%m-%d %H:%M:%S")tThe ${IP} passwd is modify OKt" >> M_pass.log
else
echo -e "$(date " %Y-%m-%d %H:%M:%S")tThe ${IP} passwd is modify failtplease check!t" >> /var/log/M_pass.log
fi
done
