在之前的版本中关闭防火墙等服务的命令是 `service iptables stop` `/etc/init.d/iptables stop` 在RHEL7中,其实没有这个服务 ``` [root@rhel7 ~]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.0 (Maipo) [root@rhel7 ~]# service iptables stop Redirecting to /bin/systemctl stop iptables.service [root@rhel7 ~]# /etc/init.d/iptables stop -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 ``` [root@rhel7 ~]# systemctl list-unit-files|grep enabled ``` 禁用防火墙 ``` [root@rhel7 ~]# systemctl stop firewalld.service [root@rhel7 ~]# systemctl disable firewalld.service [root@rhel7 ~]# systemctl status firewalld.service firewalld.service – firewalld – dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled) Active: inactive (dead) ``` 启动一个服务：systemctl start firewalld.service 关闭一个服务：systemctl stop firewalld.service 重启一个服务：systemctl restart firewalld.service 显示一个服务的状态：systemctl status firewalld.service 在开机时启用一个服务：systemctl enable firewalld.service 在开机时禁用一个服务：systemctl disable firewalld.service 查看服务是否开机启动：systemctl is-enabled firewalld.service;echo $? 查看已启动的服务列表：systemctl list-unit-files|grep enabled
