通过rpm或apt安装Cpanel：

sudo apt update
sudo apt install cpanel
sudo /etc/cpanel/cpanel.conf

3 配置 Cpanel

设置基本选项：

[mail]
    server = mail.example.com
    port = 53
    startd = yes
    startm = yes
    startt = yes
    startx = yes
    startu = yes
    startv = yes
    startz = yes

管理 Cpanel

1 访问控制面板

登录到主机后,输入以下命令启动Cpanel：

sudo /etc/init.d/cpanel start

访问控制面板：

http://localhost:8080

2 配置网站与邮件

配置邮件服务器：

    www Rewrite = on

3 添加用户与组

创建用户：

sudo useradd -m -d "Webmaster" -g webmaster example.com user@example.com
sudo chown -R user:webmaster /var/www/html

创建组：

sudo groupadd -m webmaster
sudo chown -R webmaster /var/www/html

4 优化与安全

4.1 资源管理

限制资源使用：

sudo cpanel /etc/cpanel/cpanel.conf
[web]
