rhel 6双网卡绑定(方法2-设置网关)
1、1：编辑ifcfg-bond0
[root@db2 ~]# cd /etc/sysconfig/network-scripts/
[root@db2 network-scripts]# cat ifcfg-bond0
DEVICE="bond0"
BOOTPROTO=none
NM_CONTROLLED=no
ONBOOT=yes
IPADDR=172.17.214.5
NETMASK=255.255.255.0
PREFIX=24
DEFROUTE=yes
GATEWAY=172.17.214.1
TYPE=Ethernet
2、2：编辑ifcfg-eth1和ifcfg-eth2
[root@db2 network-scripts]# cat ifcfg-eth1
DEVICE=eth1
BOOTPROTO=none
HWADDR=90:B1:1C:2F:C9:94
NM_CONTROLLED=no
ONBOOT=yes
TYPE=Ethernet
IPV6INIT=no
USERCTL=no
MASTER=bond0
SLAVE=yes
You have mail in /var/spool/mail/root
[root@db2 network-scripts]# cat ifcfg-eth2
DEVICE=eth2
BOOTPROTO=none
HWADDR=90:B1:1C:2F:C9:96
NM_CONTROLLED=no
ONBOOT=yes
TYPE=Ethernet
IPV6INIT=no
USERCTL=no
MASTER=bond0
SLAVE=yes
[root@db2 network-scripts]#
3、3：编辑/etc/modprobe.d/dist.conf
[root@db1 network-scripts]# vi /etc/modprobe.d/dist.conf
增加两行
alias bond0 bonding
options bond0 miimon=1000 mode=1
4、4：编辑/etc/rc.d/rc.local
[root@db2 modprobe.d]# cd /etc/rc.d/
[root@db2 rc.d]# vi rc.local
增加一行：
ifenslave bond0 eth1 eth2
5、5：关闭NetworkManager 并设置永久关闭
[root@db1 network-scripts]# chkconfig NetworkManager off
[root@db2 rc.d]# chkconfig --list | grep Net
NetworkManager 0:off 1:off 2:off 3:off 4:off 5:off 6:off
6、6：重启服务器
[root@db2 ~]# ifconfig
