unit firewalld.service not found,service分开解释

systemctl status firewalld.service 时报错Unit firewalld.service could not be found. 然后查了很多资料都说执行下面这个就解决了systemctl unmask firewaCentos7关闭防火墙执行命令systemctl status firewalld.service 时报错Unit firewalld.service could not be found.然后

[root@controller ~]#systemctl restart firewalld//重启防火墙[root@controller ~]#firewall-cmd --zone=public --query-port=5672/tcp//查看5672端口是否如果提示：Unit firewalld.service could not be found. 说明防火墙没有安装，需要安装yuminstallfirewalld firewall-config 1 重启、关闭、开启firewalld.servi

1.下载安装firewall-cmd yum install firewalld systemd -y 2.查看服务器上是否安装了firewall systemctl status firewalld 3.开启防火墙systemctl start firservice iptables stop 1 打开防火墙：service iptables start 1 firewalld 方式启动：systemctl start firewalld 查看状态：systemctlstatusfirewalld 禁用，禁止开机启动：system

Unit iptables.service could not be found. 解决方案：1. 安装iptables-services yum install iptables-services 2. 启动iptables systemctl enable iptables systemctl sta报错FirewallD is not running的原因是防火墙未开启在systemctl status firewalld中查看firewalld的状态，可以看到当前dead的状态，即防火墙未打开。使用命令：

CentOS7出现Unitiptables.servicecouldnotbefound CentOS7默认的防火墙不是iptables,而是firewalle. 出现此情况可能是iptables防火墙未安装。停止firewalld服务systemctlsystemctl disable firewalld.service#禁止firewall开机启动firewall-cmd --state#查看默认防火墙状态(关闭后显示notrunning,开启后显示running) 3、firewal
