Embodiment 1
[0039] This embodiment provides a cross-network segment server OS deployment system, such as figure 1 As shown, specifically, the cross-network segment server OS deployment system includes:
[0040] Central node, intermediate nodes and child nodes. Among them, the central node and the intermediate nodes constitute the management layer. A three-layer switch is responsible for the network interconnection between the central node of network segment a and the first network card of each intermediate node with dual cards, and establishes a management layer cluster to realize cross-network segment server network interconnection. The intermediate node with the best performance is selected from the intermediate nodes as the candidate central node, and the data of the candidate central node is synchronized with the central node. Once the central node fails, the candidate central node will immediately take over the work of the central node to avoid the interruption of the deployment tas...
Embodiment 2
[0042] This embodiment provides a cross-network segment server OS deployment system, including:
[0043] Central node, intermediate nodes and child nodes. Among them, the central node and the intermediate nodes constitute the management layer, and a three-layer switch is responsible for the network interconnection between the central server of network segment a and the intermediate nodes each equipped with dual cards, so as to realize the network interconnection of cross-network segment servers. The intermediate node has dual network cards, wherein the first network card is connected to the network of the central node in network segment a, and the second network card is connected to the child nodes of other network segments. Since there are multiple intermediate nodes in the management layer, the second network cards of different intermediate nodes are located in different network segments, and the second network card of an intermediate node is connected to child nodes in one ...
Embodiment 3
[0046] refer to figure 2 , the present embodiment provides a cross-network segment server OS deployment method, comprising the following steps:
[0047] The central node deploys the new version system to the child nodes under a certain network segment, and queries the intermediate node in the same network segment as the target child node, and the intermediate node is the responsible intermediate node. Send execution commands and execution files to the responsible intermediate node, where the execution commands include upgrading to XX (different versions of the operating system are optional), reinstalling the system, resetting the system, snapshot management (generating snapshots, restoring snapshots, deleting snapshots), etc. . In this embodiment, system upgrade is taken as an example for description. Execution files include iso images, configuration files required by the operating system, and automated installation scripts.
[0048]The intermediate node is responsible for...
