1. There are not many technical points in this chapter. 2. LVS-NAT cluster. This is a LVS-based load balance cluster architecture. A bunch of servers exit from a NAT server. All requests and returned information must go through the NAT server. Therefore, this Nat Server is a bottleneck and will be detailed later. 3. LVS-DR cluster. dr means "direct routing".

Use of index clusters: Create clusters of tables that are often accessed in connection statements. Do not cluster tables if the tables are only occasionally connected or their public columns are often modified. (It takes more time to modify the record's clustered key than to modify it in a nonclustered table, because Oracle must migrate the modified records to other blocks to maintain the cluster). If yo

Zookeeper practices: Zookeeper cluster mode for Embedded running, zookeeper ClusterMany Zookeeper scenarios require that we embed Zookeeper as part of our distributed application system to provide distributed services. In this case, we need to start Zookeeper through a program.
