centos多网卡绑定,centos网卡绑定1. 创建绑定接口b
RHEL6与以前的Redhat Linux版本在网络配置方面略有不同,本文详述RHEL6下多网卡绑定的配置操作过程。
1. 创建绑定接口bond0
[root@Hostname ~]#touch /etc/sysconfig/network-scripts/ifcfg-bond0
[root@Hostname ~]#cat /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
ONBOOT=yes
IPADDR=172.24.254.13
BOOTPROTO=none
NETMASK=255.255.255.0
TYPE=Ethernet
GATEWAY=172.24.254.91
BONDING_OPTS="MODE=0 MIIMON=1000"
2. 配置物理接口eth2,eth3,eth4,eth5
[root@Hostname ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth2
DEVICE=eth2
ONBOOT=yes
BOOTPROTO=none
TYPE=Ethernet
[root@Hostname ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth3
DEVICE=eth3
ONBOOT=yes
BOOTPROTO=none
TYPE=Ethernet
[root@Hostname ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth4
DEVICE=eth4
ONBOOT=yes
BOOTPROTO=none
TYPE=Ethernet
[root@Hostname ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth5
DEVICE=eth5
ONBOOT=yes
BOOTPROTO=none
TYPE=Ethernet
3.配置Bonding配置文件/etc/modprobe.d/bond0.conf
[root@Hostname ~]# cat /etc/modprobe.d/bond0.conf
alias bond0 bonding
4.修改系统配置文件/etc/rc.local,在文件末尾增加如下内容
ifenslave bond0 eth2 eth3 eth4 eth5
5.重启系统,让配置生效

另外:如果在RHEL6下执行:
service network restart
时,报如下错误:
Bringing up interface bond0: Error: Connection activation failed: Device not managed by NetworkManager
此错误是因为系统中默认由NetworkManager服务管理网络,可以将其停止:
[root@Hostname ~]#chkconfig NetworkManager off
[root@Hostname ~]#service NetworkManager stop
[root@Hostname ~]#chkconfig network on
[root@Hostname ~]#service network restart
注意NetworkManager区分大小写。
