1, the scenario described
Because of business development, need to deploy a set of ORACLE 11g RAC achieve the high availability, so the company newly allocated two physical machines, each physical machine to configure four network cards, 2 Zhangqian Zhao, Zhang Wanzhao 2
Now planned as follows:
Zhang Qianzhao card 2, the card do double bindings use standby mode, as a heartbeat
2 Zhang Wanzhao card, the card do double bound using a load balancing mode, as a business
To achieve dual use adapter binding link aggregation service team NetworkManager service group under the rhel7.
2. Preparation
2.1 confirmation card information
Use ifconfig command to see confirmation card information
[root@db1 ~]$ ifconfig
