firewalld防火墙配置

撸了今年阿里、腾讯和美团的面试,我有一个重要发现.......>>

1、管理防火墙

查看状态:systemctl status firewalld
启动:systemctl start firewalld
停止:systemctl stop firewalld
重启:systemctl restart firewalld
开机时启动:systemctl enable firewalld
开机时禁用:systemctl disable firewalld

2、查看防火墙状态

查看防火墙状态:firewall-cmd --state
查看防火墙规则(默认区域public):firewall-cmd --list-all
查看防火墙规则(指定区域work):firewall-cmd --list-all --zone=work
查看防火墙规则(所有区域):firewall-cmd --list-all-zones
重新加载服务(保持状态信息):firewall-cmd --reload
重新加载服务(舍弃状态信息):firewall-cmd --complete-reload

 

       -V, --version
       Print the version string of firewalld. This option is not combinable with other options.

       -q, --quiet
       Do not print status messages.

   Status Options
       --state
       Check whether the firewalld daemon is active (i.e. running). Returns an exit code 0 if it is active, RUNNING_BUT_FAILED if failure occurred on startup, NOT_RUNNING otherwise. See the section
       called “EXIT CODES”. This will also print the state to STDOUT.

       --reload
       Reload firewall rules and keep state information. Current permanent configuration will become new runtime configuration, i.e. all runtime only changes done until reload are lost with reload if
       they have not been also in permanent configuration.

       Note: Runtime changes applied via the direct interface are not affected and will therefore stay in place until firewalld daemon is restarted completely.

       --complete-reload
       Reload firewall completely, even netfilter kernel modules. This will most likely terminate active connections, because state information is lost. This option should only be used in case of
       severe firewall problems. For example if there are state information problems that no connection can be established with correct firewall rules.

       Note: Runtime changes applied via the direct interface are not affected and will therefore stay in place until firewalld daemon is restarted completely.

       --runtime-to-permanent
       Save active runtime configuration and overwrite permanent configuration with it. The way this is supposed to work is that when configuring firewalld you do runtime changes only and once you're
       happy with the configuration and you tested that it works the way you want, you save the configuration to disk.

   Log Denied Options
       --get-log-denied
       Print the log denied setting.

       --set-log-denied=value
       Add logging rules right before reject and drop rules in the INPUT, FORWARD and OUTPUT chains for the default rules and also final reject and drop rules in zones for the configured link-layer
       packet type. The possible values are: all, unicast, broadcast, multicast and off. The default setting is off, which disables the logging.

       This is a runtime and permanent change and will also reload the firewall to be able to add the logging rules.

   Automatic Helpers Options
       --get-automatic-helpers
       Print the automatic helpers setting.

       --set-automatic-helpers=value
       For the secure use of iptables and connection tracking helpers it is recommended to turn AutomaticHelpers off. But this might have side effects on other services using the netfilter helpers as
       the sysctl setting in /proc/sys/net/netfilter/nf_conntrack_helper will be changed. With the system setting, the default value set in the kernel or with sysctl will be used. Possible values are:
       yes, no and system. The default value is system.

       This is a runtime and permanent change and will also reload the firewall to be able to make the helpers usable.

   Permanent Options
       --permanent
       The permanent option --permanent can be used to set options permanently. These changes are not effective immediately, only after service restart/reload or system reboot. Without the --permanent
       option, a change will only be part of the runtime configuration.

       If you want to make a change in runtime and permanent configuration, use the same call with and without the --permanent option.

       The --permanent option can be optionally added to all options further down where it is supported.

   Zone Options
       --get-default-zone
       Print default zone for connections and interfaces.

       --set-default-zone=zone
       Set default zone for connections and interfaces where no zone has been selected. Setting the default zone changes the zone for the connections or interfaces, that are using the default zone.

       This is a runtime and permanent change.

       --get-active-zones
       Print currently active zones altogether with interfaces and sources used in these zones. Active zones are zones, that have a binding to an interface or source. The output format is:

           zone1
         interfaces: interface1 interface2 ..
         sources: source1 ..
           zone2
         interfaces: interface3 ..
           zone3
         sources: source2 ..


       If there are no interfaces or sources bound to the zone, the corresponding line will be omitted.

       [--permanent] --get-zones
       Print predefined zones as a space separated list.

       [--permanent] --get-services
       Print predefined services as a space separated list.

       [--permanent] --get-icmptypes
       Print predefined icmptypes as a space separated list.

       [--permanent] --get-zone-of-interface=interface
       Print the name of the zone the interface is bound to or no zone.

       [--permanent] --get-zone-of-source=source[/mask]|MAC|ipset:ipset
       Print the name of the zone the source is bound to or no zone.

       [--permanent] --info-zone=zone
       Print information about the zone zone. The output format is:

           zone
         interfaces: interface1 ..
         sources: source1 ..
         services: service1 ..
         ports: port1 ..
         protocols: protocol1 ..
         forward-ports:
               forward-port1
               ..
         source-ports: source-port1 ..
         icmp-blocks: icmp-type1 ..
         rich rules:
               rich-rule1
               ..

       [--permanent] --list-all-zones
       List everything added for or enabled in all zones. The output format is:

           zone1
         interfaces: interface1 ..
         sources: source1 ..
         services: service1 ..
         ports: port1 ..
         protocols: protocol1 ..
         forward-ports:
               forward-port1
               ..
         icmp-blocks: icmp-type1 ..
         rich rules:
               rich-rule1
               ..
           ..

       --permanent --new-zone=zone
       Add a new permanent and empty zone.

       --permanent --new-zone-from-file=filename [--name=zone]
       Add a new permanent zone from a prepared zone file with an optional name override.

       --permanent --delete-zone=zone

       For the rich language rule syntax, please have a look at firewalld.richlanguage(5).

   Options to Handle Bindings of Interfaces
       Binding an interface to a zone means that this zone settings are used to restrict traffic via the interface.

       Options in this section affect only one particular zone. If used with --zone=zone option, they affect the zone zone. If the option is omitted, they affect default zone (see --get-default-zone).

       For a list of predefined zones use firewall-cmd --get-zones.

       An interface name is a string up to 16 characters long, that may not contain ' ', '/', '!' and '*'.

       [--permanent] [--zone=zone] --list-interfaces
       List interfaces that are bound to zone zone as a space separated list. If zone is omitted, default zone will be used.

       [--permanent] [--zone=zone] --add-interface=interface
       Bind interface interface to zone zone. If zone is omitted, default zone will be used.

       If the interface is under control of NetworkManager, it is at first connected to change the zone for the connection that is using the interface. If this fails, the zone binding is created in
       firewalld and the limitations below apply. For interfaces that are not under control of NetworkManager, firewalld tries to change the ZONE setting in the ifcfg file, if the file exists.

       As a end user you don't need this in most cases, because NetworkManager (or legacy network service) adds interfaces into zones automatically (according to ZONE= option from ifcfg-interface file)
       if NM_CONTROLLED=no is not set. You should do it only if there's no /etc/sysconfig/network-scripts/ifcfg-interface file. If there is such file and you add interface to zone with this
       --add-interface option, make sure the zone is the same in both cases, otherwise the behaviour would be undefined. Please also have a look at the firewalld(1) man page in the Concepts section.
       For permanent association of interface with a zone, see also 'How to set or change a zone for a connection?' in firewalld.zones(5).

       [--zone=zone] --change-interface=interface
       If the interface is under control of NetworkManager, it is at first connected to change the zone for the connection that is using the interface. If this fails, the zone binding is created in
       firewalld and the limitations below apply. For interfaces that are not under control of NetworkManager, firewalld tries to change the ZONE setting in the ifcfg file, if the file exists.

       Change zone the interface interface is bound to to zone zone. It's basically --remove-interface followed by --add-interface. If the interface has not been bound to a zone before, it behaves like
       --add-interface. If zone is omitted, default zone will be used.

       [--permanent] [--zone=zone] --query-interface=interface
       Query whether interface interface is bound to zone zone. Returns 0 if true, 1 otherwise.

       [--permanent] --remove-interface=interface
       If the interface is under control of NetworkManager, it is at first connected to change the zone for the connection that is using the interface. If this fails, the zone binding is created in
       firewalld and the limitations below apply.

       For the addion or change of interfaces that are not under control of NetworkManager: firewalld tries to change the ZONE setting in the ifcfg file, if an ifcfg file exists that is using the
       interface.

       Only for the removal of interfaces that are not under control of NetworkManager: firewalld is not trying to change the ZONE setting in the ifcfg file. This is needed to make sure that an ifdown
       of the interface will not result in a reset of the zone setting to the default zone. Only the zone binding is then removed in firewalld then.

       Remove binding of interface interface from zone it was previously added to.

   Options to Handle Bindings of Sources
       Binding a source to a zone means that this zone settings will be used to restrict traffic from this source.

       A source address or address range is either an IP address or a network IP address with a mask for IPv4 or IPv6 or a MAC address or an ipset with the ipset: prefix. For IPv4, the mask can be a
       network mask or a plain number. For IPv6 the mask is a plain number. The use of host names is not supported.

       Options in this section affect only one particular zone. If used with --zone=zone option, they affect the zone zone. If the option is omitted, they affect default zone (see --get-default-zone).

       For a list of predefined zones use firewall-cmd [--permanent] --get-zones.

       [--permanent] [--zone=zone] --list-sources
       List sources that are bound to zone zone as a space separated list. If zone is omitted, default zone will be used.

       [--permanent] [--zone=zone] --add-source=source[/mask]|MAC|ipset:ipset
       Bind the source to zone zone. If zone is omitted, default zone will be used.

       [--zone=zone] --change-source=source[/mask]|MAC|ipset:ipset
       Change zone the source is bound to to zone zone. It's basically --remove-source followed by --add-source. If the source has not been bound to a zone before, it behaves like --add-source. If zone
       is omitted, default zone will be used.

       [--permanent] [--zone=zone] --query-source=source[/mask]|MAC|ipset:ipset
       Query whether the source is bound to the zone zone. Returns 0 if true, 1 otherwise.

       [--permanent] --remove-source=source[/mask]|MAC|ipset:ipset
       Remove binding of the source from zone it was previously added to.

       --permanent --path-icmptype=icmptype
       Print path of the icmptype configuration file.

   Direct Options
       The direct options give a more direct access to the firewall. These options require user to know basic iptables concepts, i.e.  table (filter/mangle/nat/...), chain (INPUT/OUTPUT/FORWARD/...),
       commands (-A/-D/-I/...), parameters (-p/-s/-d/-j/...) and targets (ACCEPT/DROP/REJECT/...).

       Direct options should be used only as a last resort when it's not possible to use for example --add-service=service or --add-rich-rule='rule'.

       The first argument of each option has to be ipv4 or ipv6 or eb. With ipv4 it will be for IPv4 (iptables(8)), with ipv6 for IPv6 (ip6tables(8)) and with eb for ethernet bridges (ebtables(8)).

       [--permanent] --direct --get-all-chains
       Get all chains added to all tables. This option concerns only chains previously added with --direct --add-chain.

       [--permanent] --direct --get-chains { ipv4 | ipv6 | eb } table
       Get all chains added to table table as a space separated list. This option concerns only chains previously added with --direct --add-chain.

       [--permanent] --direct --add-chain { ipv4 | ipv6 | eb } table chain
       Add a new chain with name chain to table table. Make sure there's no other chain with this name already.

       There already exist basic chains to use with direct options, for example INPUT_direct chain (see iptables-save | grep direct output for all of them). These chains are jumped into before chains
       for zones, i.e. every rule put into INPUT_direct will be checked before rules in zones.

       [--permanent] --direct --remove-chain { ipv4 | ipv6 | eb } table chain
       Remove chain with name chain from table table. Only chains previously added with --direct --add-chain can be removed this way.

       [--permanent] --direct --query-chain { ipv4 | ipv6 | eb } table chain
       Return whether a chain with name chain exists in table table. Returns 0 if true, 1 otherwise. This option concerns only chains previously added with --direct --add-chain.

       [--permanent] --direct --get-all-rules
       Get all rules added to all chains in all tables as a newline separated list of the priority and arguments. This option concerns only rules previously added with --direct --add-rule.

       [--permanent] --direct --get-rules { ipv4 | ipv6 | eb } table chain
       Get all rules added to chain chain in table table as a newline separated list of the priority and arguments. This option concerns only rules previously added with --direct --add-rule.

       [--permanent] --direct --add-rule { ipv4 | ipv6 | eb } table chain priority args
       Add a rule with the arguments args to chain chain in table table with priority priority.

       The priority is used to order rules. Priority 0 means add rule on top of the chain, with a higher priority the rule will be added further down. Rules with the same priority are on the same level
       and the order of these rules is not fixed and may change. If you want to make sure that a rule will be added after another one, use a low priority for the first and a higher for the following.

       [--permanent] --direct --remove-rule { ipv4 | ipv6 | eb } table chain priority args
       Remove a rule with priority and the arguments args from chain chain in table table. Only rules previously added with --direct --add-rule can be removed this way.

       [--permanent] --direct --remove-rules { ipv4 | ipv6 | eb } table chain
       Remove all rules in the chain with name chain exists in table table. This option concerns only rules previously added with --direct --add-rule in this chain.

       [--permanent] --direct --query-rule { ipv4 | ipv6 | eb } table chain priority args
       Return whether a rule with priority and the arguments args exists in chain chain in table table. Returns 0 if true, 1 otherwise. This option concerns only rules previously added with --direct
       --add-rule.

       --direct --passthrough { ipv4 | ipv6 | eb } args
       Pass a command through to the firewall.  args can be all iptables, ip6tables and ebtables command line arguments. This command is untracked, which means that firewalld is not able to provide
       information about this command later on, also not a listing of the untracked passthoughs.

       [--permanent] --direct --get-all-passthroughs
       Get all passthrough rules as a newline separated list of the ipv value and arguments.

       [--permanent] --direct --get-passthroughs { ipv4 | ipv6 | eb }
       Get all passthrough rules for the ipv value as a newline separated list of the priority and arguments.

       [--permanent] --direct --add-passthrough { ipv4 | ipv6 | eb } args
       Add a passthrough rule with the arguments args for the ipv value.

       [--permanent] --direct --remove-passthrough { ipv4 | ipv6 | eb } args
       Remove a passthrough rule with the arguments args for the ipv value.

       [--permanent] --direct --query-passthrough { ipv4 | ipv6 | eb } args
       Return whether a passthrough rule with the arguments args exists for the ipv value. Returns 0 if true, 1 otherwise.

   Lockdown Options
       Local applications or services are able to change the firewall configuration if they are running as root (example: libvirt) or are authenticated using PolicyKit. With this feature administrators can
       lock the firewall configuration so that only applications on lockdown whitelist are able to request firewall changes.

       The lockdown access check limits D-Bus methods that are changing firewall rules. Query, list and get methods are not limited.

       The lockdown feature is a very light version of user and application policies for firewalld and is turned off by default.

       --lockdown-on
       Enable lockdown. Be careful - if firewall-cmd is not on lockdown whitelist when you enable lockdown you won't be able to disable it again with firewall-cmd, you would need to edit
       firewalld.conf.

       This is a runtime and permanent change.

       --lockdown-off
       Disable lockdown.

       This is a runtime and permanent change.

       --query-lockdown
       Query whether lockdown is enabled. Returns 0 if lockdown is enabled, 1 otherwise.

   Lockdown Whitelist Options
       The lockdown whitelist can contain commands, contexts, users and user ids.

       If a command entry on the whitelist ends with an asterisk '*', then all command lines starting with the command will match. If the '*' is not there the absolute command inclusive arguments must
       match.

       Commands for user root and others is not always the same. Example: As root /bin/firewall-cmd is used, as a normal user /usr/bin/firewall-cmd is be used on Fedora.

       The context is the security (SELinux) context of a running application or service. To get the context of a running application use ps -e --context.

       Warning: If the context is unconfined, then this will open access for more than the desired application.

       The lockdown whitelist entries are checked in the following order:
       1. context
       2. uid
       3. user
       4. command

       [--permanent] --list-lockdown-whitelist-commands
       List all command lines that are on the whitelist.

       [--permanent] --add-lockdown-whitelist-command=command
       Add the command to the whitelist.

       [--permanent] --remove-lockdown-whitelist-command=command
       Remove the command from the whitelist.

       [--permanent] --query-lockdown-whitelist-command=command
       Query whether the command is on the whitelist. Returns 0 if true, 1 otherwise.

       [--permanent] --list-lockdown-whitelist-contexts
       List all contexts that are on the whitelist.

       [--permanent] --add-lockdown-whitelist-context=context
       Add the context context to the whitelist.

       [--permanent] --remove-lockdown-whitelist-context=context
       Remove the context from the whitelist.

       [--permanent] --query-lockdown-whitelist-context=context
       Query whether the context is on the whitelist. Returns 0 if true, 1 otherwise.

       [--permanent] --list-lockdown-whitelist-uids
       List all user ids that are on the whitelist.

       [--permanent] --add-lockdown-whitelist-uid=uid
       Add the user id uid to the whitelist.

       [--permanent] --remove-lockdown-whitelist-uid=uid
       Remove the user id uid from the whitelist.

       [--permanent] --query-lockdown-whitelist-uid=uid
       Query whether the user id uid is on the whitelist. Returns 0 if true, 1 otherwise.

       [--permanent] --list-lockdown-whitelist-users
       List all user names that are on the whitelist.

       [--permanent] --add-lockdown-whitelist-user=user
       Add the user name user to the whitelist.

       [--permanent] --remove-lockdown-whitelist-user=user
       Remove the user name user from the whitelist.

       [--permanent] --query-lockdown-whitelist-user=user
       Query whether the user name user is on the whitelist. Returns 0 if true, 1 otherwise.

   Panic Options
       --panic-on
       Enable panic mode. All incoming and outgoing packets are dropped, active connections will expire. Enable this only if there are serious problems with your network environment. For example if the
       machine is getting hacked in.

       This is a runtime only change.

       --panic-off
       Disable panic mode. After disabling panic mode established connections might work again, if panic mode was enabled for a short period of time.

       This is a runtime only change.

       --query-panic
       Returns 0 if panic mode is enabled, 1 otherwise.

EXAMPLES
       For more examples see http://fedoraproject.org/wiki/FirewallD

   Example 1
       Enable http service in default zone. This is runtime only change, i.e. effective until restart.

       firewall-cmd --add-service=http

   Example 2
       Enable port 443/tcp immediately and permanently in default zone. To make the change effective immediately and also after restart we need two commands. The first command makes the change in runtime
       configuration, i.e. makes it effective immediately, until restart. The second command makes the change in permanent configuration, i.e. makes it effective after restart.

       firewall-cmd --add-port=443/tcp
       firewall-cmd --permanent --add-port=443/tcp
