本文介绍了如何在RHEL7/CentOS7系统中将firewalld服务停用并替换为传统的iptables服务。内容包括关闭firewalld服务、安装iptables服务包、启动及管理iptables服务、保存防火墙规则等步骤。

With RHEL 7 / CentOS 7, firewalld was introduced to manage iptables.

将firewalld-替换为iptables

1. 关闭防火墙

    1.1 systemctl stop firewalld

    1.2 systemctl mask firewalld

2. 安装iptables-services package:

    2.1 yum install iptables-services

    2.2 Enable the service at boot-time:

        systemctl enable iptables

    2.3 Managing the service

        systemctl [stop|start|restart] iptables

    2.4 Saving your firewall rules can be done as follows:

        or
        /usr/libexec/iptables/iptables.init save
