The following brings you an introduction to the practice of http load balancing, hoping to give you some help in practical application. Load balancing involves many things, and there are not many theories. There are many books on the Internet. Today, we will use the accumulated experience in the industry to do an answer.

F5 http load balancing practice

1, Network Topology

2. Configure the address pool node first.

3. Configure the node pool.

3. Add virtual service policy

4. The client uses LoadRunner streaming test to check the number of real-time connections in F5. The number of connections is about 160.

Summary: this is the simplest http load configuration. Note that according to the lab topology, we have to do the source NAT strategy. Why? The client and the CVM are in the same network segment and are only connected through the switch. The client accesses the VIP. The destination IP is 10.23.22.205 and the source IP is 10.23.22.1. After F5 load, without NAT address translation, the source IP is still 10.23.22.1 and the destination IP is 10.23.58.4. The server needs to reply after receiving the message, that is, the reverse message source IP is 10.23.58.4 and the destination IP is 10.23.22.1, so the reverse message is directly sent to the client through the switch, that is, the reverse message does not pass through the F5 load device will lead to access failure, and the client initially accesses 10.23.22.205, and finally the reverse message becomes the source is 10.23.58.4, which the client must not recognize.
