linux deb系 rpm系 配置永久IP

rpm：

1.IP a 查看网卡名 ens256

2.uuidgen ens256 生成UUID

3./etc/sysconfig/network-scripts add ifcfg-ens256 

4.sudo vim ifcfg -ens256 

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens256#NAME
UUID=4e3c8350-6e7f-47e2-8b9d-b64ba0531d79#UUID
DEVICE=ens256#deviceName
ONBOOT=yes
IPADDR=8.47.221.183
NETMASK=255.255.224.0
#GATEWAY=8.47.192.1
#DNS1=8.47.192.1

8.47.0.0/19 via 8.47.192.1#onboot route

4.重启网络服务：systemctl restart network.service

deb:

1.sudo vim /etc/network/interfaces

2.add 

alfred@vm:~$ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto ens160
iface ens160 inet static
address 10.150.56.62
gateway 10.150.56.1
netmask 255.255.254.0
dns-nameservers 10.129.0.220
up route add -net 10.0.0.0 netmask 255.255.0.0 gw 10.150.56.1

auto ens192
iface ens192 inet static
address 8.46.221.73
#gateway 8.46.192.1　　#can not add two gateway other network use route 
netmask 255.255.224.0
up route add -net 8.46.0.0 netmask 255.255.0.0 gw 8.46.192.1

auto ens224
iface ens224 inet static
address 8.47.221.73
netmask 255.255.224.0
up route add -net 8.47.0.0 netmask 255.255.0.0 gw 8.47.192.1

3.重启网络服务：systemctl restart network.service

RHEL:

十分原始

1.路径同rpm 内容：

重点是这几个配置
TYPE=Ethernet
BOOTPROTO=static
NAME=enp0s3
ONBOOT=yes
IPADDR=地址
NETMASK=掩码
GATEWAY=网关
DNS1=你的DNS

#临时ip ifconfig eth0 x.x.x.x netmask 255.255.x.0 up

使用ethtool检查端口是否up
