CentOS6.5多网卡绑定

分类:CentOS教程 阅读:63940 次

CentOS6.5与以前的Redhat Linux版本在网络配置方面略有不同,本文详述CentOS6.5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。
