Compile and install ipvsadm on the server Load balancer.(2) Scheduling Algorithm: The Load balancer of LVS has the following scheduling rules: round-robin (RR); Weighted Round-Robin (WRR; each new connection is assigned to each physical server in turn. Least-connected (LC); weighted least-connected (wlc). Each new connection is assigned

Same big pot dispatch with weights (Weighted round-robin scheduling WRR)WRR-With a weighted polling method. Each request is sequentially dispatched in the real server, but more jobs are assigned to the larger server. 3. Assign who does not work (Least-connection LC)LC-Dispatched according to the minimum number of connections 4. Who does not work wi

LVS Dr Mode
This mode also requires a common IP configuration on the Distributor and all RS, which is the VIP
Unlike IP tunnel, he will change the MAC address of the packet to the MAC address of the RS.
After the RS receives the packet, it restores the original packet so that the target IP is the VIP, because the VIP is configured on all RS, so it will consider itself

Conventions in URLs
The nouns in the URL are in the plural form.
The question of whether the URL name is singular or plural has been controversial for a long time. The nouns in URLs generally correspond to tables in the database. The tables store similar data. In practice, I use the plural form forcibly, which looks more comfortable.
