ubuntn22.04安装iredmail

首先，需要编辑 /etc/hosts 文件，找到含有你的 VPS IP 地址的那一行；如果没有，则添加一行。内容如下：

127.0.0.1 mail.*****.com mail

其中, 127.0.0.1 可换为你的服务器 IP 地址，后面依次填入长主机名和短主机名，切记不可填反。

然后，我们找到 VPS 的 /etc/hostname 文件，编辑里面的内容为 mail （域名的前缀）

这样，就设置好了主机名。重启 VPS后我们检查一下是否设置正确：

执行：hostname

此时我们应该只能看到短主机名 mail. 如果你看到了长主机名 mail.jichang.ml , 说明之前设置错误，请重新检查上述步骤。

执行：hostname -f

此时，我们应该只能看到长主机名 mail.jichang.ml

这样，我们就全部设置好了主机名（hostname）, 可以进行接下来的其他操作了

安装配置iRedMail

安装过程会以交换形式进行，需要注意的地方有

安装完成后查看文件 /root/iRedMail-1.6.2/iRedMail.tips， 这里记录会所有iRedMail相关服务和组件的信息。

(5)配置 SSL 证书

配置前准备：

sudo vim /etc/nginx/sites-enabled/00-default-ssl.conf

修改server_name这一行为：

server_name mail.mydomain.com;

停止nginx

sudo service nginx stop

如果不配置nginx的server_name和停止nginx服务，certbot会安装失败。

使用 Let's Encrypt 提供免费的 SSL 证书，访问https://certbot.eff.org/instructions?ws=nginx\&os=ubuntufocal根据官方文档进行操作

由于Ubuntu22.04自带snap，可以跳过snap的安装，直接更新snap

sudo snap install core; sudo snap refresh core

sudo snap install --classic certbot

sudo certbot --nginx

配置过程中会提示你输入证书域名： mail.mydomain.com

配置结束后启动nginx

sudo service nginx start
