Bonding is a combination of many links of network cards in the server for higher speed as well as a backup plan when a network card has a problem.
Install Bonding
Step 1: install Bonding by command
modprobe –first-time bonding
Step 2: Check the successful installation of Bonding using the command
lsmod | grep “bonding”
Step 3: Create a configuration file for bond0 with the command
vi / etc / sysconfig / network-scripts / ifcfg-bond0
Step 4: Configure the file ifcfg-bond0
+ Mode = 0 : balance-rr
+ mode = 1 : active – backup
+ mode = 2 : balance – xor
+ mode = 3 : broadcast
+ mode = 4 : 802.3ad
+ mode = 5 : balance – tlb
+ mode = 6 : balance – alb
Step 5: There are 2 network cards, respectively ens33 ens36, configure the ens33 network card to enter the configuration file using the command
vi / etc / sysconfig / network-scripts / ifcfg-ens33
Step 6: Configure the ens33 . network card
DEVICE = ens33
TYPE = Ethernet
ONBOOT = yes
BOOTPROTO = none
NM_CONTROLLED = no
MASTER = bond0
SLAVE = yes
Step 7: Go to the ens36 network card configuration file using the command
vi / etc / sysconfig / network-scripts / ifcfg-ens36
Step 8: Configure the ens36 . network card
DEVICE = ens36
TYPE = Ethernet
ONBOOT = yes
BOOTPROTO = yes
NM_CONTROLLED = no
MASTER = bond0
SLAVE = yes
Step 9: Restart the network service with the command
service network restart
Step 10: Check the installed bonding with the command
cat / proc / net / bonding / bond0
Conclusion
We have just completed the basic installation and use of bonding steps, here we can provide network redundancy options for the server, or load balance for the network, depending on usage needs.
