Linux网络管理—配置静态IP地址

1. CentOS7

编辑配置文件:/etc/sysconfig/network-scripts/ifcfg-ens33(ens33 为网卡名)

TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="static"			# 1
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="ens33"
UUID="c85c107e-c186-4c5f-bfab-431e8a3ffd32"
DEVICE="ens33"
ONBOOT="yes"				# 2
IPADDR="192.168.1.152"		# 3
NETMASK="255.255.255.0"		# 4
GATEWAY="192.168.1.2"		# 5
DNS1="222.201.130.30"		# 6
DNS2="222.201.130.33"		# 7
$ sudo service network restart

2. CentOS8

网络接口配置文件同 CentOS7,但重启接口配置需使用如下方式:

$ sudo nmcli c reload
$ sudo nmcli c up ens33

3. Ubuntu16

编辑配置文件:/etc/network/interfaces

auto lo
iface lo inet loopback

auto ens33
iface ens33 inet static
address 192.168.1.153
netmask 255.255.255.0
gateway 192.168.1.2
dns-nameservers 222.201.130.30 222.201.130.33
$ sudo ip addr flush dev ens33
$ sudo /etc/init.d/networking restart

4. Ubuntu18

编辑配置文件:/etc/netplan/01-network-manager-all.yaml

network:
  version: 2
  renderer: NetworkManager
  ethernets:
    ens33:
      dhcp4: no
      dhcp6: no
      addresses: [192.168.1.200/24]
      gateway4: 192.168.1.2
      nameservers:
        addresses: [222.201.130.30, 222.201.130.33]
$ sudo netplan apply
