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 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
