Read the Linux server double network card double IP and single network card double IP configuration method one, double network card double IP.

Eth0 is China Telecom and eth2 is China Unicom.

# cd / etc/sysconfig/network-scripts/# vi ifcfg-eth0DEVICE=eth0HWADDR=00:e0:b1:07:d5:86ONBOOT=yesBOOTPROTO=noneIPADDR=1.2.3.4NETMASK=255.255.255.0GATEWAY=1.2.3.1TYPE=Ethernet# wq# vi ifcfg-eth2DEVICE=eth2HWADDR=00:e0:b2:09:d5:87ONBOOT=yesBOOTPROTO=noneIPADDR=2.3.4.5NETMASK=255.255.255.0TYPE=Ethernet# wq

Note: eht1 does not add gateway addresses.

Then do policy routing (the policy routing file is provided by the computer room).

Second, single network card and double IP. # cd / etc/sysconfig/network-scripts/# cp ifcfg-eth0 ifcfg-eth0:1# vi ifcfg-eth0DEVICE=eth0ONBOOT=yesBOOTPROTO=noneHWADDR=00:0c:29:7d:dc:03IPADDR=192.168.0.10 / / Telecom IP address. NETMASK=255.255.255.0GATEWAY=192.168.0.1TYPE=Ethernet# vi ifcfg-eth0:1DEVICE=eth0:1ONBOOT=yesBOOTPROTO=noneHWADDR=00:0c:29:7d:dc:03IPADDR=172.16.0.10 / / Unicom IP address. NETMASK=255.255.255.0TYPE=Ethernet

Note: only need to change the device name and IP address, do not add the gateway.

Activate the network card.

# ifup eth0:1 verifies that the IP address is valid. # ifconfig eth0:1# ping 192.168.0.10# ping 172.16.0.10

Then do policy routing.

Third, configure policy routing.

Put the route list file in any directory, give executable permissions, then execute it, and finally add boot autorun in the rc.local file.

# cd / etc/sysconfig/# chmod 775 static-routes / / assume that the route list file named static-routes is placed in the / etc/sysconfig/ directory. #. / static-routes# cd / etc/rc.d/# vi rc.local/etc/sysconfig/static-routes# wq
