vps获取root权限，ssh升级root命令

获取VPS的root权限，随意更改root密码的一键脚本，已测试EUserv德鸡，Hax IPV6，甲骨文oracle、谷歌云gpc、IBM Linux one、亚马逊云azurz等

wget -N https://gitlab.com/rwkgyg/vpsroot/raw/main/root.sh && bash root.sh

脚本具体代码如下：

#!/bin/bash
red='\033[0;31m'
bblue='\033[0;34m'
plain='\033[0m'
red(){ echo -e "\033[31m\033[01m$1\033[0m";}
green(){ echo -e "\033[32m\033[01m$1\033[0m";}
yellow(){ echo -e "\033[33m\033[01m$1\033[0m";}
white(){ echo -e "\033[37m\033[01m$1\033[0m";}
readp(){ read -p "$(yellow "$1")" $2;}
