VServer
Add Vserver
Operation Steps
After the creation of CLB instance, you can click Details to go to the VServer Management page to add VServer.
-
On the VServer Management page, click Add VServer.
-
Fill in the configuration information to create the VServer. See the detailed configuration instructions below.
Configuration Instructions
The options for creating a VServer listener include the following:
Configuration | Description |
---|---|
VServer Name | The name of the VServer, required. |
Protocol and Port | The protocol and port listened by the listener, including HTTP/HTTPS/TCP/UDP protocols. |
Load Balancing Algorithm | The way the listener load balances data packets. |
Service Node | Usually, adding service nodes is after the creation of the VServer listener. This option provides a way to copy the service node pool configuration from other VServers to quickly create using existing configurations. |
Service Session Persistence | For HTTP/HTTPS protocols, use default/custom keywords to maintain user login status. For TCP (packet forwarding)/UDP, the default connection timeout is 900s. After enabling/disabling session persistence, the current long connection may be interrupted and reconnected. After enabling session persistence, you can set the session persistence time. The session maintenance time and connection timeout are both set. |
Connection Maintenance Time | Under TCP request agent mode, or HTTP, HTTPS protocols, you can select the effective time of the client request connection. The optional time range is [1-86400] seconds. |
Node Health Check | Health check type. UDP protocol supports port check, PING check and UDP check; TCP protocol supports port check; HTTP/HTTPS protocol supports port check and HTTP check. For details on health check principles, rules, and use cases, see Health Check. |
