Configuration centos7 next card

Usually by modifying the configuration file to modify the way:

  NIC configuration file location / etc / sysconfig / network-scripts / ifcfg-ens33  

  DNS configuration file /etc/resolv.conf location

     Static hostname configuration file location / etc / hosts

Profiles order to take effect:

  1. hosts
  2. NIC configuration file / etc / sysconfig / network-scripts / ifcfg-ens33
  3. DNS configuration file resolv.conf

Configure a static ip

example:

vi    /etc/sysconfig/network-scripts/ifcfg-ens33

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=ens33
UUID=10d6dd25-6383-480f-8c74-3cc4ca3dd78b
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.1.88
BROADCAST=192.168.1.255
"ifcfg-ens33" 19L, 370C

Example of the configuration parameters, see below

Parameter values ​​are not case sensitive, single and double quotes, even without the quotes

  • TYPE:Ethernet、IPsec
  • DEVICE: Network Interface Name
  • BOOTPROTO : boot protocol address

    none: do not use the startup protocol address

    BOOTP : Use BOOTP protocol

    dhcp : dhcp Use Agreement

    static : Static address protocol

  • ONBOOT: whether to activate when the system starts

    yes : activated

    NO : not activated (this is the default value)

  • IPADDR : IP address
  • NETMASK : Subnet Mask
  • GATEWAY : Gateway address
  • BROADCAST : Broadcast address
  • The HWADDR / the MACADDR: the MAC address, only a set, can not conflict with each other simultaneously provided
  • PEERDNS : Specifies whether the DNS . If you eat DHCP protocol, the default is yes

      yes : If the DNS settings, modify /etc/resolv.confg in DNS

      NO : /etc/resolv.confg does not modify the DNS

  •  DNS1 / DNS2: When PEERDNS to yes when /etc/resolv.conf will be written in
  • NM_CONTROLLED : whether by the Network Manager to control the network interface, the changes take effect immediately after saving, usually no recommendations

      yes : by the Network Manager control

      NO : Network Manager help control

  • USERCTL : user access control

      yes: non- root user to allow control of the network interface

      no: non- root user is not allowed to control the network interface

  • IPV6INIT : whether IPv6

      yes : Support IPv6

      NO : do not support IPv6

  • IPV6ADDR : the IPv6 address / prefix length

   If you need to access external networks through the domain name, you need to add dns, modify /etc/resolv.conf configuration reference

; generated by /usr/sbin/dhclient-script
nameserver 202.101.172.35             
nameserver 114.114.114.114
search localdomain
  • Address nameserver dns server
