CentOS 7.5設定網路

CentOS 7.5設定網路

1、ifconfig命令找不到

解決方法：安裝net-tools.x86_64工具包  yum install net-tools.x86_64

2、iptables無法使用

解決方法：yum install iptables-services

vi /etc/sysconfig/iptables #設定防火牆引數

# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

:wq! #儲存退出

systemctl restart iptables.service #最後重新啟動防火牆使設定生效

systemctl enable iptables.service #設定防火牆開機啟動
