linux设置静态ip,防火墙放行端口

linux设置静态ip

首先找到配置目录

cd /etc/sysconfig/network-scripts

我的是ifcfg-eth0

vi ifcfg-eth0

具体配置

DEVICE="eth0"
BOOTPROTO="static"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
IPADDR=192.168.5.128
NETMASK=255.255.255.0
GATEWAY=192.168.5.1
DNS1=8.8.8.8

reboot重启

防火墙放行端口

vi /etc/sysconfig/iptables

-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 6379 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
