FIG. 1 is a schematic flow diagram of a method of one embodiment of the invention.

and step 120, testing the high-availability service to be tested based on the deployed test environment.

In order to facilitate understanding of the present invention, the principle of the virtualization platform-based high available service testing method of the present invention is combined with the process of testing the high available service of the server in the embodiment to further describe the virtualization platform-based high available service testing method of the present invention.
The high-availability service testing method based on the virtualization platform comprises the following steps:
step K1: and deploying the test environment. The implementation method of the step K1 comprises the following steps:
and step K11, building an ICOS (InCloudOpenStack, which is a virtualization system based on openstack) virtualization platform, wherein the virtualization platform comprises four test hosts, the test hosts are mutually communicated, and highly available services to be tested are deployed in the test hosts. In specific implementation, a person skilled in the art can also set up other common virtualization platforms according to actual situations.
Step K12 is then performed.
And step K12, creating a management network, a storage network and a tenant network on each test host.
The high available service test needs to comprehensively judge the HA execution conditions at three network levels, namely, the management network, the storage network, and the tenant network.
And K13, realizing the three-network separation of the created management network, the created storage network and the created tenant network on each test host.
First, each test host is entered. Then, virtual network cards are respectively set for a management network, a storage network and a tenant network configured in the test host, so that separation of the tenant network, the management network and the storage network is realized. Specifically, the management network, the storage network and the tenant network on the test host correspond to three independent virtual network cards respectively.
The three independent virtual network cards corresponding to the management network, the storage network and the tenant network in each test host are sequentially as follows:
managing the network card: named "api _ interface";
a storage network card: named storage _ interface;
the tenant network card: named "smart _ interface", is the network card used by the virtual machine service network.
Optionally, for a tent _ interface (tenant network card):
when the Virtual machine service network of the test host uses a vxlan (Virtual Extensible LAN) network model, a physical network card is independently allocated to the Virtual machine service network of the test host, which is beneficial to improving the high availability judgment of high available service to a certain extent;
when a Virtual machine service Network of a test host uses a vlan (Virtual Local Area Network) Network model, independently allocating a vlan to a tenant Network, and allocating an ip to the tenant Network in a sub-interface manner; at this time, the uplink switch port of the tenant _ interface network card is in trunk mode, and allows the tenant network vlan and the virtual machine service vlans of other test hosts to pass through.
The content of the network card subinterface configuration file can refer to the following contents:
TYPE＝Eehernet
BOOTPROTO＝static
NAME＝eno2.201
DEVICE＝eno2.201
ONBOOT＝yes
IPADDR＝182.201.13
NETMASK＝233.233.233.0
VLAN＝yes
taking a test host as the node 153 as an example, a virtual network card is set for the management network, the storage network and the tenant network of the node 153, so as to realize separation of the tenant network, the management network and the storage network in the node 153, and configuration can be realized by referring to the following scripts:
Node153 network_interface＝eno1 neutron_exterface
＝eno2 storage_interface＝eno2.201tenant_interface＝eno2.202
similarly, the separate configuration of the management network, the storage network and the tenant network in other test hosts can be realized.
And after the configuration is finished, opening a globals.yml file in the test host, and annotating the storage _ interface and the tenant _ interface, namely adding "#" in the front of the configuration line of the storage _ interface and the tenant _ interface for annotation.
Then, the configuration information enters a deployment node (namely, each test host for performing separate configuration of the management network, the storage network and the tenant network), and the following commands are executed to enable the relevant configuration to take effect:
kola-ansible post-deploy-i/root/multimode-t masakari，consul
at this point, any two virtual network cards between the test hosts are all interconnected through the network.
And K2, testing the high-availability service to be tested based on the deployed test environment.
After the configuration takes effect, the built virtualization platform can be used for testing the related high-availability service.
The test of the high available service to be tested in the step K2 includes a floating vip high available service test of the control node and a high available service test of the computation node.
In this embodiment, the floating vip high available service test of the control node includes the following steps:
firstly, three test hosts are selected from four test hosts and deployed as control nodes, which is beneficial to ensuring the stable operation of the environment to a certain extent. Floating ip will randomly select the control node.
And then, searching the control node where the floating ip is located through the ip a command, and marking the control node as a first control node. The first control node is the control node where the floating ip is currently located.
And then, executing a shutdown now command to close the first control node.
Then, on the other two control nodes (three control nodes are deployed in this embodiment), the control node where the floating ip is located is searched through the ip a command, and if the control node where the floating ip is located is found, the test is passed, that is, the high available service (HA) in the control node functions normally.
In addition, the high available service test of the computing node described in this embodiment includes the following steps:
firstly, two of the four test hosts are selected and deployed as computing nodes.
Each compute node is deployed under a multinode file.
And then, configuring the BMC corresponding to each computing node to ensure that the computing nodes can be started and closed through the background.
Then, a high-availability cluster with an automatic recovery mode is created, and each computing node is added to the high-availability cluster.
And then, opening the HA switch of each computing node in the high-availability cluster.
Then, a corresponding number of virtual machines are created on any one of the computing nodes, and then an ifdown command is executed to disable the computing service of the computing node. The created virtual machines comprise a virtual machine in a running state and a virtual machine in a closed state. In specific implementation, the two computing nodes in this embodiment are denoted as 145 node and 146 node, and a virtual machine in a running state and a virtual machine in a shutdown state are established on the 145 node. And then executing an ifdown command to disable the storage network card of the 145 node, namely closing the computing service of the 145 node, wherein the HA switch of the 145 node is automatically closed.
And then, checking the evacuation condition of the virtual machine created on the corresponding computing node on other computing nodes, and if the virtual machine is evacuated to other computing nodes, passing the test. For example, in this embodiment, the 146 node may be automatically logged in and an evacuation condition of the virtual machine created on the 145 node may be checked, and if the virtual machine is evacuated to the 146 node, the test is passed, that is, there is a high available service (HA) in the computing node that functions normally.
In summary, in the method 100 described in this embodiment, the test host in the built virtualization platform can be configured as a control node for testing and can also be configured as a computing node for testing, so that different hosts are not used for deploying the control node and the computing node, which is helpful for reducing the number of hosts for testing high available services (HA) of the server to a certain extent, and is further helpful for smooth testing to a certain extent.
