Abstract

The application provides a network resource access method and device. The network resource access method comprises the following steps: receiving a DNS request sent by a client, and the DNS request carries a target domain name to be accessed by the client; determining an IP address corresponding to the target domain name; detecting a state of each service server in a target Web server cluster if the determined IP address is a virtual IP address of the target Web server cluster; and returning the virtual IP address of a backup Web server cluster to the client if each service server is in an abnormal state, so that the client accesses the network resource based on the virtual IP address of the backup Web server cluster. By means of the network resource access method provided by the application, the problem that the network access of the client is interrupted due to abnormalities of the service servers in the target Web server cluster is avoided.

Description

technical field [0001] The present application relates to the field of computer communication, in particular to a method and device for accessing network resources. Background technique [0002] A web server cluster usually includes a load balancing device and at least one service server. Among them, the load balancing device can be used to perform load balancing processing on the network access requests sent by the clients. The service server is mainly used to process the network access requests forwarded by the load balancing device. [0003] The web server cluster is configured with a virtual IP address. The client can access network resources in the Web server cluster based on the virtual IP address of the Web server cluster. [0004] For example, when a client accesses a network resource of the web server cluster, the client may send a network access request to the web server cluster based on the virtual IP address. After receiving the network access request sent by...
