Detailed Description
The invention is described in further detail below with reference to specific embodiments.
The method for configuring seven-layer load balancing for the OVN architecture is applied to a cloud platform comprising OVN architecture and a plurality of virtual machines, and comprises the following specific steps.
A. Building a virtual machine under the OVN architecture, configuring a network of the virtual machine to connect to OVN private network;
B. installing a HaProxy load balancer on the virtual machine, and accessing the HaProxy load balancer into OVN private networks;
C. the output end of OVN is linked to the HaProxy load balancer through a private network, so that the HaProxy load balancer is used as an external port of OVN, and the virtual machine under the OVN architecture realizes external interaction of an upper layer through the HaProxy load balancer.
Referring to fig. 1, a virtual machine is deployed in an OVN private network environment, and a HaProxy load balancer with seven-layer network capability is installed inside, and a network of the virtual machine is configured and connected to a logical switch in which OVN private network is located, where the virtual machine occupies a private network IP of OVN private network, such as 10. x.x.2. In the OVN private network environment, the original three virtual machines respectively occupy the other three IPs of the private network: 10, x.x.3, 10.x.x.4, 10.x.x.5, at this time, since the HaProxy load balancer is set to be under the same private network as the members of the private network, the HaProxy load balancer as a link intermediary brings its seven-layer network capability into OVN architecture, so that OVN architecture has a load balancer with seven-layer network capability.
After the seven-layer load balancing method is configured on the cloud platform of the OVN architecture, the Haproxy load balancer receives external upper-layer interaction information, and then the load of each virtual machine under the OVN architecture is automatically configured, so that the load balancing of the OVN architecture is controlled.
In the method, each time a new load balancer is added, the virtual machine is manually deployed, the HaProxy is installed in the virtual machine, and the specific OVN logic switch is associated, so that the whole process is complicated. Moreover, it is time consuming to deploy the virtual machine itself, which results in a slow creation process and poor experience of the load balancer. When deploying the virtual machine, a user needs to deploy the virtual machine according to the load conditions of different physical machines, which greatly increases the maintenance cost.
To this end, an adaptation engine with load balancer deployment service is constructed: load Balancer Distribution Engine (LBDE). After the user initiates OVN a load balancer creation request, the load balancer distribution engine LBDE automatically calculates the physical machine with the largest amount of remaining resources on the platform, selects and deploys the load balancer on it. When the load balancer is deleted, the load balancer distribution engine LBDE automatically finds the location of the corresponding virtual machine and performs the deletion.
As shown in fig. 2, the cloud platform management system presets a mirror image of the HaProxy load balancer on each physical machine in advance, generates an external snapshot for the mirror image, and uses the external snapshot as a precondition for deploying the load balancer. After the HaProxy load balancer is deployed on the physical machine manually for the first time, the state and information of the mirror image of the HaProxy load balancer are mapped to the storage of each physical machine from the memory.
Specifically, firstly, creating a virtual machine image qemu-img create-f raw/images/vm1. raw 8G of a Haproxy load balancer; then, starting the virtual machine OVN/images/vm 1.raw, at this time, because there is no content in the image, the running result will prompt that no bootable device can be found, for this purpose, after creating the image qemu-img create-f < fmt > -o < options > < fname > < size >, snapshot processing qemu-img snapshot-c booting vm2.qcow2 is performed to keep it in a fast recoverable state, when a HaProxy load balancer needs to be deployed on the physical machine, then performing fast recovery: qemu-img snapshot-a 1/images/vm2. qcow2, and then starting the virtual machine from OVN, so as to obtain a virtual machine image file of the Haproxy load balancer.
According to the method, the characteristics of the qcow2 disk are utilized, qemu-img is used based on the external snapshot, so that the disk of the virtual machine is quickly created in a second level, and a new virtual machine is constructed based on the disk. The deployment of the virtual machine is automatically realized through a Load Balancer Distribution Engine (LBDE), the maintenance cost is reduced, and the creation of the load balancer virtual machine is realized by adopting an external snapshot recovery method of a mirror image, so that the speed is high.
The above description is only the embodiments of the present invention, and the scope of protection is not limited thereto. The insubstantial changes or substitutions will now be made by those skilled in the art based on the teachings of the present invention, which fall within the scope of the claims.
