Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings by way of specific examples, which are illustrative of the present invention and are not limited to the following embodiments.
Example one
As shown in fig. 1, the present embodiment provides a method for supporting automatic configuration in a high availability environment, which includes the following steps:
s1, configuring the network resource weight information of any service to be deployed;
s2, generating a configuration file by the configuration and sending the configuration file to a node to be configured;
and S3, the node to be configured configures the node for the service to be deployed configured with the network resource weight according to the network resource weight information in the configuration file.
Generally, different services have different requirements on a network, for example, certain services that need to be downloaded or uploaded have higher requirements on downlink bandwidth and uplink bandwidth of the network, and when configuring the network resource weight information, one or more pieces of network resource configuration information of the services to be partially configured may be configured according to the requirements. The network resource weight information of the service to be deployed configured in this embodiment includes a name of the service to be deployed, to which the network resource weight needs to be configured, and a corresponding upload weight, download weight, and network delay weight. For the service to be deployed configured with the network resource weight, allocating an execution node for the service to be deployed according to the configured weight, specifically:
calculating the execution weight of each configuration node aiming at the service to be deployed according to the network resource weight;
and for any service to be deployed, selecting the configuration node corresponding to the maximum execution weight as the node to be deployed.
Wherein the execution weight omega of the node i to be configured for the service j to be deployediThe calculation formula is as follows:
in the formula, ai、bi、ciRespectively the uploading rate, the downloading rate and the network delay of the node i to be configured; n is the number of nodes to be configured; lambda [ alpha ]j、μj、νjRespectively representing the uploading weight, the downloading weight and the network delay weight of the service j to be deployed.
It should be noted that, for a service to be deployed that is not configured with network resource weight information, the service to be deployed is randomly allocated to a certain node for execution.
In addition, the configuration of the service to be deployed also includes a network configuration and a program mapping configuration, and when the method configures the network resource weight information of any service to be deployed in step S1, the method also configures the network configuration information of the service to be deployed and the program mapping information of the service to be deployed. The two configurations are also generated in a configuration file, and the node to be configured performs network and program mapping configuration of the service to be deployed according to the network configuration information and the program mapping information in the configuration file.
The configured network configuration information of the service to be deployed comprises the name of each service to be deployed, the configured virtual IP address, the bound network card and the subnet mask. The program mapping information for configuring the service to be deployed is specifically a name of the service to be deployed corresponding to the defined program. It should be noted that, in some cases, the same program module may be called by multiple services, that is, one program may correspond to at least one service to be deployed.
An example is provided below to illustrate the present invention.
In this example, a highly available environment with three nodes is to be deployed, and nine services, namely mysql, bmc, influx, etc., need to be deployed highly available on the three nodes. The three nodes are respectively provided with four network cards eth0, eht1, eth2 and eth3 which are respectively connected with four mutually isolated networks.
(1) Configuring network configuration information for a service to be deployed
The network configuration information for the nine services to be deployed is shown in table 1 below.
TABLE 1 network configuration of a service to be deployed
| eth0 | eth1 | eth2 | eth3 | |
| Subnet mask | 20 | 20 | 20 | 24 |
| ISPIM | 100.7.32.83 | |||
| mysql | 100.7.32.85 | |||
| influx | 100.7.32.83 | |||
| bmc | 100.7.32.96 | |||
| gui | 192.168.11.182 | |||
| dsm | 192.168.13.77 | |||
| host | 192.168.13.77 | |||
| north1 | 192.168.11.183 | |||
| north2 | 192.168.12.18 |
(2) Configuring program mapping information for a service to be deployed
The program mapping information for configuring the service to be deployed is specifically a name of the service to be deployed corresponding to the defined program, and codes of the program mapping information are as follows, wherein the worker and normal program modules provide services for a plurality of networks.
When the service needs to be added or deleted, the corresponding relation of the service only needs to be added or deleted in the network configuration of the service and the corresponding relation of the service and the program. For example, when the north2 service needs to be deleted, the network configuration information is as shown in table 2 below.
Table 2 network configuration of service to be deployed after deleting normal 2 service
The correspondence between the service and the program when deleting the normal 2 service is as follows:
(3) configuring network resource weight information for a service to be deployed
In this example, the gui, mysql, infilux services have higher requirements on network delay, the bmc service has higher requirements on network download, and the network resource weight configuration of the services is shown in the following codes. The key value represents the name of the service, and the corresponding value is an array containing three numerical values which respectively represent the weight of downloading, uploading and network delay.
In a highly available environment, nine services are configured at each node, but not every node runs nine services, but each service is performed by a specific node. For services configured with network resource weight information (such as the above gui, mysql, influx, and bmc services), which node is to execute is determined by calculating the execution service weight of each node. And for the service which is not configured with the weight information of the network resource, allocating the service to a certain node for execution.
For the service configured with the network resource weight, the node executes the weight calculation process as follows: and testing the network information of each node by using a network testing module, calculating the testing result through a calculation rule, uploading and downloading, testing the uploading and downloading rates of the nodes respectively, and then carrying out normalization processing. The uploading rate, the downloading rate and the network delay of a certain node are respectively ai、bi、ciFor any service j (a service configured with network resource weight), the upload weight, download weight, and network delay weight of the service are λj、μj、νj(e.g., gui service with three values of 1,1,9), the weight ω of the execution of the service by the node i is giveniThe node with the largest execution weight is taken to execute the service as follows:
in this example, n is 3, that is, three nodes are provided.
After all the configuration is completed, generating a configuration file and sending the configuration file to the node to be configured, analyzing the network configuration information of the service to be deployed and the program mapping information of the service to be deployed from the configuration file by the node to be configured, judging whether network resource weight information exists or not, analyzing the network resource weight information if the network resource weight information exists, and completing automatic environment configuration according to the information.
