RedHat Enterprise Linux 7关闭防火墙方法

在之前的版本中关闭防火墙等服务的命令是

1 service iptables stop  2   3 /etc/init.d/iptables stop

在RHEL7中,其实没有这个服务

1 [root@rhel7 ~]# cat /etc/redhat-release  2 Red Hat Enterprise Linux Server release 7.0 (Maipo)  3 [root@rhel7 ~]# service iptables stop  4 Redirecting to /bin/systemctl stop  iptables.service  5 [root@rhel7 ~]# /etc/init.d/iptables stop  6 -bash: /etc/init.d/iptables: No such file or directory

原来在RHEL7开始，使用systemctl工具来管理服务程序，包括了service和chkconfig

1 [root@rhel7 ~]# systemctl list-unit-files|grep enabled  2 cups.path                                   enabled  3 abrt-ccpp.service                           enabled  4 abrt-oops.service                           enabled  5 abrt-vmcore.service                         enabled  6 abrt-xorg.service                           enabled  7 abrtd.service                               enabled  8 accounts-daemon.service                     enabled  9 atd.service                                 enabled 10 auditd.service                              enabled 11 avahi-daemon.service                        enabled 12 bluetooth.service                           enabled 13 chronyd.service                             enabled 14 crond.service                               enabled 15 cups.service                                enabled 16 dbus-org.bluez.service                      enabled 17 dbus-org.fedoraproject.FirewallD1.service   enabled 18 dbus-org.freedesktop.Avahi.service          enabled 19 dbus-org.freedesktop.ModemManager1.service  enabled 20 dbus-org.freedesktop.NetworkManager.service enabled 21 dbus-org.freedesktop.nm-dispatcher.service  enabled 22 display-manager.service                     enabled 23 dmraid-activation.service                   enabled 24 firewalld.service                           enabled 25 firstboot-graphical.service                 enabled 26 gdm.service                                 enabled 27 getty@.service                              enabled 28 hypervkvpd.service                          enabled 29 hypervvssd.service                          enabled 30 irqbalance.service                          enabled 31 iscsi.service                               enabled 32 ksm.service                                 enabled 33 ksmtuned.service                            enabled 34 libstoragemgmt.service                      enabled 35 libvirtd.service                            enabled 36 lvm2-monitor.service                        enabled 37 mdmonitor.service                           enabled 38 microcode.service                           enabled 39 ModemManager.service                        enabled 40 multipathd.service                          enabled 41 NetworkManager-dispatcher.service           enabled 42 NetworkManager.service                      enabled 43 nfs-lock.service                            enabled 44 packagekit-offline-update.service           enabled 45 postfix.service                             enabled 46 rhsmcertd.service                           enabled 47 rngd.service                                enabled 48 rpcbind.service                             enabled 49 rsyslog.service                             enabled 50 rtkit-daemon.service                        enabled 51 smartd.service                              enabled 52 spice-vdagentd.service                      enabled 53 sshd.service                                enabled 54 sysstat.service                             enabled 55 systemd-readahead-collect.service           enabled 56 systemd-readahead-drop.service              enabled 57 systemd-readahead-replay.service            enabled 58 tuned.service                               enabled 59 vmtoolsd.service                            enabled 60 avahi-daemon.socket                         enabled 61 cups.socket                                 enabled 62 dm-event.socket                             enabled 63 iscsid.socket                               enabled 64 iscsiuio.socket                             enabled 65 lvm2-lvmetad.socket                         enabled 66 rpcbind.socket                              enabled 67 default.target                              enabled 68 graphical.target                            enabled 69 nfs.target                                  enabled 70 remote-fs.target                            enabled

禁用防火墙

1 [root@rhel7 ~]# systemctl stop firewalld.service  2 [root@rhel7 ~]# systemctl disable firewalld.service  3 [root@rhel7 ~]# systemctl status firewalld.service  4 firewalld.service – firewalld – dynamic firewall daemon  5    Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled)  6    Active: inactive (dead)  7   8 Jul 29 22:25:43 rhel7 systemd[1]: Started firewalld – dynamic firewall daemon.  9 Jul 29 22:43:29 rhel7 systemd[1]: Stopping firewalld – dynamic firewall daemon… 10 Jul 29 22:43:29 rhel7 systemd[1]: Stopped firewalld – dynamic firewall daemon. 11 Jul 29 22:44:14 rhel7 systemd[1]: Stopped firewalld – dynamic firewall daemon. 12 Jul 29 22:44:15 rhel7 systemd[1]: Stopped firewalld – dynamic firewall daemon. 13 Jul 29 22:44:19 rhel7 systemd[1]: Starting firewalld – dynamic firewall daemon… 14 Jul 29 22:44:19 rhel7 systemd[1]: Started firewalld – dynamic firewall daemon. 15 Jul 29 22:44:21 rhel7 systemd[1]: Stopping firewalld – dynamic firewall daemon… 16 Jul 29 22:44:21 rhel7 systemd[1]: Stopped firewalld – dynamic firewall daemon. 17 Jul 29 22:44:32 rhel7 systemd[1]: Stopped firewalld – dynamic firewall daemon.

1 启动一个服务：systemctl start firewalld.service  2 关闭一个服务：systemctl stop firewalld.service  3 重启一个服务：systemctl restart firewalld.service  4 显示一个服务的状态：systemctl status firewalld.service  5 在开机时启用一个服务：systemctl enable firewalld.service  6 在开机时禁用一个服务：systemctl disable firewalld.service  7 查看服务是否开机启动：systemctl is-enabled firewalld.service;echo $?  8 查看已启动的服务列表：systemctl list-unit-files|grep enabled

批注：对于这个文章的提示，我不知道是没有得到操作要领还是怎么回事，反正标题的问题我没有得到解决。
