bonding

主力鯖のネットワークを増強するのだ。EXPI9402PTBLK(amazon:\6100)でbonding。まあ、気休めかも。

CentOS 6.6での設定。

[/etc/modprobe.d/bonding]

alias bond0 bonding

[/etc/sysconfig/network-scripts/ifcfg-bond0]

DEVICE=bond0
BOOTPROTO=static
IPADDR=x.y.z.100
NETMASK=255.255.255.0
GATEWAY=x.y.z.1
DNS1=x.y.z.1
ONBOOT=yes

[/etc/sysconfig/network-scripts/ifcfg-eth0]

DEVICE=eth0
BOOTPROTO=none
