如何在CentOS上安装基于Web的控制面板

更新系统并重启；2. 设置完整域名作为主机名；3. 下载并运行CWP安装脚本（CentOS 7/8对应不同版本）；4. 通过浏览器访问http://服务器IP:2030或:2082登录；5. 配置防火墙开放2030和2082端口；6. 完成后修改MySQL默认密码、保护phpMyAdmin、配置域名、启用SSL并创建普通用户账户；7. 注意CWP非活跃维护，仅建议用于学习或测试，生产环境应选用ISPConfig或CyberPanel等更安全的替代方案，且必须加强系统安全措施如更新系统、使用强密码、禁用root登录等，安装完成后务必执行安全加固步骤。

Installing a web-based control panel on CentOS simplifies server management, especially for users who prefer a graphical interface over command-line tools. These panels help manage websites, databases, emails, DNS, and more with minimal effort. Here’s how to install one on CentOS.

Choose the Right Control Panel

Before installing, decide which control panel fits your needs. Popular options include:

• cPanel & WHM – Commercial, feature-rich, widely used, but requires a license.
• Plesk – Also commercial, user-friendly, supports Linux and Windows.
• Webmin – Free, lightweight, open-source, good for basic server tasks.
• ISPConfig – Free, open-source, powerful, supports multiple servers and services.
• CentOS Web Panel (CWP) – Free, designed specifically for CentOS/RHEL, easy setup.

For this guide, we’ll use CentOS Web Panel (CWP) since it's free and built for CentOS.

Install CentOS Web Panel (CWP)

Important: Use a fresh installation of CentOS 7 or CentOS 8. CWP is not recommended for production servers due to limited updates and potential security concerns. Use it for testing or learning unless you're confident in securing it.

1. Update Your System

yum update -y

Reboot if a kernel update was applied:

reboot

2. Set a Proper Hostname

CWP requires a fully qualified hostname.

hostnamectl set-hostname server.yourdomain.com

Replace server.yourdomain.com with your actual domain.

3. Install CWP

For CentOS 7:

cd /tmp
wget http://centos-webpanel.com/cwp-el7-latest
sh cwp-el7-latest

For CentOS 8:

cd /tmp
wget http://centos-webpanel.com/cwp-el8-latest
sh cwp-el8-latest

The installation may take 10–20 minutes. It installs Apache, PHP, MySQL/MariaDB, and other tools.

4. Access the Web Interface

After installation completes, you’ll see login details in the terminal.

• Admin URL: http://your-server-ip:2030
• User URL: http://your-server-ip:2082

Log in with your root credentials.

Note: If you can't access the port, check your firewall.

5. Configure Firewall

Allow ports 2030 (admin panel) and 2082 (user panel):

For firewalld (default on CentOS):

firewall-cmd --permanent --add-port=2030/tcp
firewall-cmd --permanent --add-port=2082/tcp
firewall-cmd --reload

If you’re using a cloud provider (like AWS or DigitalOcean), also open these ports in the security group.

Post-Installation Steps

• Change the default MySQL root password if prompted.
• Secure phpMyAdmin by restricting access via IP or renaming the alias.
• Set up your domain in CWP under “Apache Config”.
• Enable SSL for your sites using Let’s Encrypt (available in CWP).
• Create user accounts for hosting domains instead of using root.

Security Considerations

Web-based control panels expose services to the internet, increasing attack surface.

• Keep the system updated.
• Use strong passwords and SSH key authentication.
• Disable root SSH login.
• Change default panel ports if possible.
• Regularly monitor logs.

CWP is not actively maintained as of recent years. For production environments, consider ISPConfig or CyberPanel (for OpenLiteSpeed) as more secure and updated alternatives.

Final Notes

Installing a web control panel on CentOS is straightforward with CWP, but always weigh usability against security. For beginners, it's a great tool to learn server management. For production, go with more robust and supported options.

Basically, install CWP via their script, open the right ports, and log in through the browser. Just don’t skip the security steps.
