概述
This module allows for addition or deletion of services and ports (either TCP or UDP) in either running or permanent firewalld rules.
firewalld模块用来添加、删除防火墙规则。
常用变量
service
: Name of a service to add/remove to/from firewalld.The service must be listed in output of firewall-cmd --get-services.
指定放行的服务,此服务必须要在firewall-cmd --get-services查询的到。
permanent
: Should this configuration be in the running firewalld configuration or persist across reboots. As of Ansible 2.3, permanent operations can operate on firewalld configs when it is not running.
Note that if this is no’, immediate is assumed yes’.
保存策略,下次启动的时候自动加载。
state
: Enable or disable a setting.For ports: Should this port accept (enabled) or reject (disabled) connections.The states present’ and absent’ can only be used in zone level operations (i.e. when no other parameters but zone and state are set).
(Choices: absent, disabled, enabled, present)
指定防火墙策略状态,enable表示策略生效,disable表示策略禁用,present新建策略,absent删除策略。
port
: Name of a port or port range to add/remove to/from firewalld. Must be in the form PORT/PROTOCOL or PORT-PORT/PROTOCOL for port ranges.
指定放行的端口/协议。
zone
: The firewalld zone to add/remove to/from.
Note that the default zone can be configured per system but public’ is default from upstream.Available choices can be extended based on per-system configs, listed here are “out of the box” defaults.Possible values include block’, dmz’, drop’, external’, home’, internal’, `public’, trusted’, work’.
指定防火墙信任级别。
drop: 丢弃所有进入的包,而不给出任何响应
block: 拒绝所有外部发起的连接,允许内部发起的连接
public: 允许指定的进入连接
external: 同上,对伪装的进入连接,一般用于路由转发
dmz: 允许受限制的进入连接
work: 允许受信任的计算机被限制的进入连接,类似 workgroup
home: 同上,类似 homegroup
internal: 同上,范围针对所有互联网用户
trusted: 信任所有连接
interface
: The interface you would like to add/remove to/from a zone in firewalld.
指定接口属于哪个信任级别。
source
: The source/network you would like to add/remove to/from firewalld.
指定网段。
immediate
: Should this configuration be applied immediately, if set as permanent
防火墙策略立即生效。
示例
案例1:在默认信任级别新增放行https协议数据的策略,下次重启的时候策略自动加载
- firewalld:
service: https
permanent: yes
state: enabled
原先的状态,public信任级别中没有https
[root@control ~]# ansible node1 -a 'firewall-cmd --zone=public --list-all'
node1 | CHANGED | rc=0 >>
public (active)
target: default
icmp-block-inversion: no
interfaces: eth0
sources:
services: cockpit dhcpv6-client ssh
ports:
protocols:
masquerade: no
forward-ports:
source-ports:
icmp-blocks:
rich rules:
新增放行https协议数据的策略,下次重启的时候策略自动加载
[root@control ~]# ansible node1 -m firewalld -a 'service=https permanent=yes state=enabled'
node1 | CHANGED => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": true,
"msg": "Permanent operation, Changed service https to enabled"
}
策略没有立马生效
