Linux bond 安装
1. 察看linux内核是否已安装了bonding模块？
# cat/boot/config-2.6.18-194.el5 |grep -ibonding如显示：CONFIG_BONDING=m则表示已安装。（注：config-2.6.18-128.el5是/boot下的一个文件，与内核的版本相关）
然后新建备份目录：# mkdir -p/opt/soft/bak2.将modprobe.conf文件进行备份
# cp/etc/modprobe.conf /opt/soft/bak/modprobe.conf然后对modprobe.conf 进行修改：
# vi /etc/modprobe.conf==================================scdb1服务器需做网卡绑定，所以加入scdb1的代码……==================================以scdb1为例：———————————————————install bond0 /sbin/modprobe -a eth0 eth1&& /sbin/modprobe bonding
–（bond0是私网，先要找出私网卡，这里是eth0,eth1）alias bond0 bondinginstall bond1 /sbin/modprobe -a eth2 eth3&& /sbin/modprobe bonding
–（bond1是公网，先要找出公网卡，这里是eth2,eth3）alias bond1 bondingoptions bonding mode=1 miimon=100 max_bonds=2——————————————————————-3. # vi/etc/sysconfig/network-scripts/ifcfg-bond0（编辑bond0，这是新建的文件）———————————————————–网卡绑定后，只有bond0一个IP，此处是在给bond0设私网IP（10.10.10.x）
DEVICE=bond0ONBOOT=yesBOOTPROTO=staticBROADCAST=10.10.10.255（根据实际情况填写）IPADDR=10.10.10.171（根据实际情况填写）NETMASK=255.255.255.0USERCTL=noIPV6INIT=no———————————————————
4. # vi/etc/sysconfig/network-scripts/ifcfg-bond1（编辑bond1，这是新建的文件）———————————————————DEVICE=bond1ONBOOT=yesBOOTPROTO=staticBROADCAST=153.16.16.255（根据实际情况填写）IPADDR=153.16.16.171（根据实际情况填写）NETMASK=255.255.255.0GATEWAY=153.16.16.29（bond1比bond0多一个网关，根据实际情况填写）USERCTL=noIPV6INIT=no
—————————————————————5. 备份以下文件（以实际网卡为准，这里是eth0~3）cp /etc/sysconfig/network-scripts/ifcfg-eth0 /opt/soft/bakcp /etc/sysconfig/network-scripts/ifcfg-eth1 /opt/soft/bakcp /etc/sysconfig/network-scripts/ifcfg-eth2 /opt/soft/bakcp /etc/sysconfig/network-scripts/ifcfg-eth3 /opt/soft/bak
—————————————————————-
然后依次修改以上文件，以eth0为例：# vi/etc/sysconfig/network-scripts/ifcfg-eth0———————————————————
vi 文件时，保留原有的HWADDR=xx:xx:xx:xx:xx:xx一栏，其余清空，然后添加DEVICE、ONBOOT、BOOTPROTO、MASTER、SLAVE选项。DEVICE=eth0（根据实际情况填写）ONBOOT=yesBOOTPROTO=staticMASTER=bond0（根据实际情况填写）SLAVE=yesHWADDR=00:1A:64:DC:AA:14(网卡对应的MAC地址)———————————————————此步为虚拟网卡bond0、bond1绑定了哪些实际的物理网卡（bond0：eth0与eth1；scdb1的bond1：eth4与eth5、scdb2的bond1：eth3与eth5）。
6.重启linux，或是重新启动网络服务# service network restart
7.察看看目前 Bonding 的狀态# ifconfig
以下为部分为ifconfig结果————————————————————————————————–[root@dbweb2 ~]# ifconfigbond0Link encap:Ethernet HWaddr00:22:19:B6:4D:35inet addr:100.100.100.4Bcast:100.100.100.255 Mask:255.255.255.0inet6 addr: fe80::222:19ff:feb6:4d35/64 Scope:LinkUP BROADCAST RUNNING MASTER MULTICASTMTU:1500 Metric:1RX packets:63 errors:0 dropped:0 overruns:0 frame:0TX packets:53 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:0RX bytes:17715 (17.2 KiB) TX bytes:13515 (13.1KiB)
