2、然后在下方可以查看得到“active（running）”，此时说明防火墙已经打开了。

3、在命令行中输入systemctlstopfirewalld.service命令，进行关闭防火墙。

4、然后再使用命令systemctlstatusfirewalld.service，在下方出现disavtive（dead），这样就说明防火墙已经关闭。

5、再在命令行中输入命令“systemctldisablefirewalld.service”命令，即可永久关闭防火墙。

Linux如何关闭防火墙

关闭防火墙

零、RHEL 6（CentOS6）

# 临时关闭防火墙

servcie iptables stop

# 永久关闭防火墙

chkconfig iptables off

一、RHEL 7 （CentOS 7）

# 开机不自动启动防火墙

sudo systemctl disable firewalld.service

# 关闭防火墙

sudo systemctl stop firewalld.service

二、 SLES

sudo chkconfig SuSEfirewall2_setup off

sudo chkconfig SuSEfirewall2_init off

sudo rcSuSEfirewall2 stop

三、Unutu

sudo service ufw stop

sudo ufw disable

开启防火墙

零、RHEL 6（CentOS6）

# 临时开启防火墙

servcie iptables start

# 永久开启防火墙

chkconfig iptables on

一、RHEL 7 （CentOS 7）

# 开机自动启动防火墙

sudo systemctl enable firewalld.service

# 关闭防火墙

sudo systemctl start firewalld.service

# 查看防火墙状态

sudo systemctl status firewall.service

# 重新启动防火墙

sudo systemctl restart firewall.service

二、 SLES

sudo chkconfig SuSEfirewall2_setup on

sudo chkconfig SuSEfirewall2_init on

或者

sudo ufw

RHEL7(CentOS7 启动关闭服务命令)

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
