版本	功能
v7版更新内容	1.由于v6版修改的比较仓促，其中设置镜像仓库有bug，修复了其中的bug，而且设置镜像仓库可以重复修改；修复了设置ip不能成功的bug；优化了设置系统别名的bug；
	2.分别有reset_v7_1版本（镜像仓库采用sed直接替换网址方式；修改ip地址采用nmcli命令方式）和reset_v7_2版本（镜像仓库和修改ip地址采用配置文件方式）。
v6版更新内容	1.由于CentOS 6和8官方已经停止支持，也就移除了其相关内容；
	2.分别有reset_v6_1版本（镜像仓库采用sed直接替换网址方式；修改ip地址采用nmcli命令方式）和reset_v6_2版本（镜像仓库和修改ip地址采用配置文件方式）；
	3.reset_v6_1添加了CentOS Stream 9用Perl语言更改镜像源的方法，优化了某些镜像仓库失效的bug，修改了某些bug。
v5版更新内容	1.优化了某些镜像仓库失效的bug；
	2.CentOS stream 9和Rocky 9修改ip的方式更改，做了相应的修改；
	3.分别有reset_v5_1版本（镜像仓库采用sed直接替换网址方式；修改ip地址采用nmcli命令方式）和reset_v5_2版本（镜像仓库和修改ip地址采用配置文件方式）；
	4.把设置PS1、设置默认文本编辑器为vim和设置history格式单独分开；
	5.修改了某些bug。
v4版更新内容	1.添加对CentOS stream 9、Rocky 9和Ubuntu 22.04系统的支持；
	2.添加Ubuntu 22.04修改IP地址和网关地址、双网卡更改IP地址；
	3.添加禁用ctrl+alt+del重启功能；
	4.修改了某些bug。
v3版更新内容	1.添加双网卡更改IP地址；
	2.添加设置系统时区。
v2版更新内容	1.添加对CentOS stream 8系统支持，添加了CentOS stream 8镜像仓库；
	2.由于CentOS 8已被废弃，修改成centos-vault的历史镜像仓库；
	3.优化Ubuntu 20.04禁用swap不生效的问题。
v1版支持功能	1.支持CentOS 6/7/8、Ubuntu 18.04/20.04、Rocky 8系统；
	2.支持功能禁用SELinux、关闭防火墙、优化SSH、设置系统别名、设置vimrc配置文件、设置软件包仓库、Minimal安装建议安装软件、安装邮件服务并配置邮件、更改SSH端口号、修改网卡名、修改IP地址和网关地址、设置主机名、设置PS1和系统环境变量、禁用SWAP、优化内核参数、优化资源限制参数、Ubuntu设置root用户登录、Ubuntu卸载无用软件包。
