v1和v2版本的区别：

v1和v2版本实现的功能都是一样的，只是实现的方式不同。

v1	v2
1.Rocky、Almalinux、CentOS系统修改ip地址采用nmcli命令方式；	1.Rocky、Almalinux、CentOS系统修改ip地址采用的是配置文件方式；
2.Rocky、Almalinux、CentOS、Ubuntu和Debian系统修改镜像仓库采用sed直接替换网址方式。	2.Rocky、Almalinux、CentOS、Ubuntu和Debian系统修改镜像仓库采用的是配置文件方式。

版本更新日志：

版本	功能
v9版更新内容	1.由于CentOS Stream 8 已于 2024 年 5 月 31 日到期， CentOS Linux 7 的生命周期结束日期是 2024 年 6 月 30 日，将CentOS Stream 8和CentOS 7的镜像仓库都改成了centos-vault仓库；把CentOS 7的epel仓库改成了epel-archive仓库；
	2.添加了对Ubuntu 24.04系统的支持；（Ubuntu 24.04的变更：网卡配置文件变成了“/etc/netplan/50-cloud-init.yaml”，镜像仓库格式变成了DEB822 格式，ssh服务的服务名变成了ssh；）
	3.添加了对Debian 12系统的支持；
	4.修改了某些bug。
v8版更新内容	1.添加了对AlmaLinux 8和9系统的支持；
	2.添加Ubuntu卸载snap的功能；
	3.修改了某些bug。
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；修复了“优化内核参数”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；

	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。

reset脚本在使用过程中需要注意的事项：

首先说明，脚本必须在root用户下使用。

# Rocky、Almalinux、和CentOS默认可以使用root用户登录不用设置，Ubuntu和Debian必须先设置root用户登录。
# 先安装lrzsz工具，把脚本传上去
raymond@ubuntu2404:~$ sudo apt -y install lrzsz
