centos 6 單網絡卡繫結雙ip

os:cnetos 6.8

初始網絡卡配置檔案

[root@localhost /]# vim /etc/sysconfig/network-scripts/ifcfg-eth0

device=eth0

type=ethernet

uuid=d3fde489-9b67-453c-84df-4827f3becf1a

onboot=yes

nm_controlled=yes

bootproto=none

ipaddr=192.168.1.110

prefix=24

gateway=192.168.1.1

dns1=114.114.114.114

defroute=yes

ipv4_failure_fatal=yes

ipv6init=no

name="system eth0"

hwaddr=00:0c:29:f6:f8:a8

last_connect=1489157101

方法一:在原網絡卡配置檔案直接增加新ip

[root@localhost /]# vim /etc/sysconfig/network-scripts/ifcfg-eth0

device=eth0

type=ethernet

uuid=d3fde489-9b67-453c-84df-4827f3becf1a

onboot=yes

nm_controlled=yes

bootproto=none

ipaddr=192.168.1.110

prefix=24

gateway=192.168.1.1

dns1=114.114.114.114

defroute=yes

ipv4_failure_fatal=yes

ipv6init=no

name="system eth0"

ipaddr2=192.168.1.111

prefix2=24

hwaddr=00:0c:29:f6:f8:a8

last_connect=1489129249

方法二:新增網絡卡配置檔案:

[root@localhost /]# cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0:0

[root@localhost /]# vim /etc/sysconfig/network-scripts/ifcfg-eth0:0

device=eth0:0

type=ethernet

uuid=d3fde489-9b67-453c-84df-4827f3becf1a

onboot=yes

nm_controlled=yes

bootproto=none

ipaddr=192.168.1.111

prefix=24

gateway=192.168.1.1

dns1=114.114.114.114

defroute=yes

ipv4_failure_fatal=yes

ipv6init=no

name="system eth0"

hwaddr=00:0c:29:f6:f8:a8

last_connect=1489130355

修改網絡卡配置檔案後,需要重啟網路服務才會生效:

[root@localhost /]# service network restart

centos6實現雙網絡卡繫結

首先確保主機上已經有涼快網絡卡並且網絡卡都已生效 然後分別編寫eth0 eth1的網絡卡配置檔案,如下圖所示 在 etc sysconfig network scripts目錄下新建ifcfg bond0檔案,檔案內容如下圖 在 etc modprobe.d目錄下新建modprobe.conf檔案,...
