CentOS防火墙状态查询方法详解

在使用CentOS操作系统时,了解防火墙的状态是确保系统安全的重要环节。本文将为您详细介绍如何查询CentOS防火墙的状态,包括命令行和图形用户界面两种方法,让您能够轻松掌握这一技能。

通过命令行查询防火墙状态

CentOS防火墙状态查询方法详解

使用命令行是最直接且高效的方法之一。在终端中输入以下命令:

systemctl status firewalld

执行该命令后,您将看到类似于以下输出的信息:

  • Active: 防火墙正在运行。
  • Inactive: 防火墙已停止。
  • Failed: 防火墙启动失败。

This method is particularly useful for server administrators who prefer working in a terminal environment. 【燎元跃动小编】建议定期检查防火墙的状态,以确保没有潜在的安全隐患。

通过图形用户界面(GUI)查看防火墙状态

If you are more comfortable using a graphical interface, CentOS also provides an easy way to check the firewall status through its GUI.

  • CENTOS 7:

    1. Navigating to “系统设置” > “安全” > “防火墙”。
    2. You will find the firewall status displayed on the "状态" tab.
  • CENTOS 8:

    Navigating to “设置” > “安全和隐私” > “防火墙”。 The firewall status will be visible at the top bar of this section.

This method is user-friendly and suitable for those who may not be familiar with command-line operations. 【燎元跃动小编】提醒大家,无论采用哪种方式,都应定期监控并维护您的网络安全策略,以保护您的数据不受威胁。

总结与建议

Totaling up, whether you choose to use command line or GUI methods, regularly checking your CentOS firewall's state is crucial for maintaining system security. Make it a habit to verify your settings and stay informed about potential vulnerabilities that could affect your server or workstation.
