ubuntu22.04下搭建iRedMail邮件服务器 - 实践

语言

安装更新包
键盘布局
安装选择
配置网络
代理设置


国内也没有被墙，可以不改。不过，最近感觉越来越慢了，可以改成阿里云的：http://mirrors.aliyun.com/ubuntu/

磁盘

调整LV大小

格式化分区

Your name：是使用在者的名称，没有太多实际意义，但是必须填写。
Your server’s name： 配置服务名
Pick a username：这个用户名为登录系统的用户名
Password：需要输入两次相同密码，建议密码设置相对复杂些，避免被爆破
下载
升级到Ubuntu Pro

默认Install OpenSSH Server未选中，通过上/下箭头移动到 Install OpenSSH Server选项，按键盘空格键可以选中该选项。

如果不选该内容，系统安装上之后无法通过SSH登录服务器。

可以什么都不选，然后直接安装。

当显示Installation complete时，表示安装完成。然后选中Cancel update and reboot进行重启系统。
