RHCE認證學習:RHEL7 網路設定

VMware Workstation 12.0.1 build-3160714

Red Hat Enterprise Linux Server release 7.0 (Maipo)

一 設定網絡卡

1，編輯網絡卡組態檔

# vim /etc/sysconfig/network-scripts/ifcfg-eno16777736

HWADDR=00:0C:29:5D:34:28

TYPE=Ethernet

BOOTPROTO=static  ##dhcp：自動獲取IP，static：靜態IP，none：不用協定

DEFROUTE=yes

PEERDNS=yes

PEERROUTES=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=yes

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_PEERDNS=yes

IPV6_PEERROUTES=yes

IPV6_FAILURE_FATAL=no

NAME=eno16777736

UUID=3af1bda7-d937-4aba-bbdf-e9c7eeef0dd9

ONBOOT=yes   ##啟動network服務時是否啟用該網絡卡，yes為啟用

IPADDR=192.168.16.91

NETMASK=255.255.255.0

GATEWAY=192.168.16.1

DNS1=8.8.8.8

2，重新啟動網路服務

#systemctl restart network

二 修改主機名

#vim /etc/hostname

cnblog.localdomain

三 修改hosts

#vim /etc/hosts

192.168.16.91   cnblog.localdomain cnblog

#hostname -i

192.168.16.91

四 單網絡卡設定雙IP

1，編輯網絡卡組態檔

#cp /etc/sysconfig/network-scripts/ifcfg-eno16777736 /etc/sysconfig/network-scripts/ifcfg-eno16777736:0

# vim /etc/sysconfig/network-scripts/ifcfg-eno16777736:0

DEVICE=eno16777736:0

HWADDR=00:0C:29:5D:34:28

TYPE=Ethernet

BOOTPROTO=static 

DEFROUTE=yes

PEERDNS=yes

PEERROUTES=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=yes

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_PEERDNS=yes

IPV6_PEERROUTES=yes

IPV6_FAILURE_FATAL=no

NAME=eno16777736

UUID=3af1bda7-d937-4aba-bbdf-e9c7eeef0dd9

ONBOOT=yes

IPADDR=192.168.16.92

NETMASK=255.255.255.0

GATEWAY=192.168.16.1

DNS1=8.8.8.8

2，重新啟動網路服務

#systemctl restart network

五 雙網絡卡系結模式

1，確定核心是否制定bonding

# cat /boot/config-3.10.0-123.el7.x86_64 | grep -i bonding

CONFIG_BONDING=m
