First, technical terms mentioned in the present application are explained:
bare metal server (Bare Metal Server, BMS): the physical server on the cloud can be seamlessly integrated with the existing cloud computing, network and other services, so that the extremely-high-performance and stable physical computing resources are provided for the service, and the physical server on the cloud can be matched with cloud products such as a cloud server (CVM), a private network (VPC) and the like for use, and the advantages of stability of the traditional host and high elasticity of resources on the cloud are integrated.
EVPN: the EVPN technique can be used to dynamically transfer MAC information, support MAC migration, and ARP suppression.
BGP EVPN: the EVPN defines a series of new BGP EVPN route types based on MP-BGP, so that different stations in the EVPN network can mutually learn MAC address information.
Underway network: the cloud service based on the bearer network is composed of various physical devices, and the bearer network ensures IP connectivity among the devices by using a routing protocol, and all the cloud services run in an underley network.
Overlay network: refers to one or more virtual logical networks constructed on the same underway network through a network virtualization technology.
The embodiment of the application provides a method for realizing high-availability bare metal service, which specifically comprises the following steps as shown in fig. 1:
s101, receiving a creation request of high-availability bare metal service of a tenant.
S102, analyzing the creation request to obtain an analyzed creation request.
The parsed creation request comprises user requirements, a subnet, a machine type, an operating system, a high-availability identifier and the like.
Specifically, after receiving a creation request of a high-availability bare metal service of a tenant, performing basic parameter verification on the creation request, and then analyzing to obtain the data.
S103, calling a private cloud network component according to the analyzed creation request, and applying for three available Overlay network IPs under the subnet corresponding to the tenant.
The two available Overlay network IPs are used as the true IPs of the two bare metals and are directly bound on a bond0 network card of the physical machine, and the other Overlay network IP is used as a floating IP of the high-availability bare metal for external service.
It should be noted that, eventually, in the overlay network, two bare metal servers and three overlay ips will be used. The reaip is that two bare metals each configure a fixed reaip, the floating IP is configured on the main server by default, and when the main server fails, the floating IP is switched to the standby server. Floating IP will be the IP for external services.
S104, installing the system of the two bare metal servers through the pre-starting execution environment according to the user requirements.
S105, logging in the bare metal service through a secure shell protocol after the bare metal server is installed, carrying out the initialization configuration of the password and the network of the bare metal, and simultaneously pulling out the high-availability agent for installation and deployment.
S106, the control plane issues configuration to the uplink switch, and the bare metal is mapped into the Overlay network through a network virtualization technology.
It should be noted that, the network virtualization technology includes, but is not limited to, VXLAN, BGP EVPN, and the like, which are not limited herein.
Optionally, in another embodiment of the present application, an implementation method of the high available bare metal service, as shown in fig. 2, further includes:
s201, continuously receiving the reported health state of the agent.
And S202, if the health state indicates that the health is abnormal, performing active-standby switching.
Wherein, the standby node newly adds a network subinterface and configures a floating IP; after the standby node agent receives the configuration, the standby node agent automatically completes the floating IP configuration.
It should be noted that, only one realpp is configured at the beginning of the standby server, and when the main fault occurs, the floating IP address is configured by means of the network subinterface. Since the external always accesses the address that is the floating IP, the switching traffic is not interrupted and no additional action is required by the accessing party.
Because of the limitation of network security on public cloud, the service of the underlay is forbidden to directly access the service of the overlay, so that the bare metal of the overlay is designed to access the high-availability control module of the underlay through the proxy, and corresponding control instructions are issued through corresponding messages, so that the automatic configuration of the high-availability bare metal is realized.
Optionally, in another embodiment of the present application, the manner of automatically completing the floating IP configuration is by configuring a sub-interface of the bond0 network card.
It should be noted that, under the same cloud region, the uplink switch of the bare metal will make a fully connected BGP neighbor, and the arp information of the bare metal under the same VPN INSTANCE will be synchronized automatically by BGP EVPN, so that even if the active and standby bare metals are distributed across the switch, after the floating IP is migrated, the synchronization of the arp information can be completed automatically.
Specifically, EVPN (Ethernet Virtual Private Network) is a VPN technology for two-layer network interconnection. The EVPN technology adopts a mechanism similar to BGP/MPLS IP VPN, defines a new network layer reachable information NLRI (Network Layer Reachability Information), namely EVPN NLRI, on the basis of BGP protocol, and defines several new BGP EVPN route types for MAC address learning and release between different sites of a two-layer network.
The original VXLAN implementation scheme has no control plane, is used for VTEP discovery and host information (including IP address, MAC address, VNI and gateway VTEP IP address) learning through traffic flooding of a data plane, and causes the VXLAN network to have a lot of flooding traffic. In order to solve the problem, VXLAN introduces EVPN as a control plane, and realizes functions of automatic discovery of VTEP, mutual notification of host information, etc. by exchanging BGP EVPN routes between VTEPs, thereby avoiding unnecessary data traffic flooding.
In summary, the EVPN newly defines several BGP EVPN routes by extending BGP protocol, and these BGP EVPN routes can be used to transfer VTEP addresses and host information, so that the EVPN is applied in VXLAN network, and VTEP discovery and host information learning can be transferred from the data plane to the control plane.
Optionally, in another embodiment of the present application, if the CPU or the memory in the health state exceeds the threshold, determining that the health is abnormal; or if the agent does not report the health state beyond the preset time interval, determining that the health is abnormal.
As shown in fig. 3, an overall framework diagram of a method for implementing a high-availability bare metal service provided in the present application includes a bare metal management and control device, a bare metal resource pool, a public cloud service, and an installed service. The bare metal management device includes an interface (API) access layer, a bare metal management module (IRONIC), and a high availability module. The bare metal resource pool comprises a proxy server.
The bare metal management module interface layer analyzes the request of creating high-availability bare metal service by the tenant and forwards the request to the high-availability module;
the high-availability module calls the VCP network component through the IRONIC module, applies for three available Overlay network IPs under the corresponding tenant subnets, wherein two REALIPs serving as two bare metals are directly bound on a bond0 network card of the physical machine, and the other IP is used as a floating IP of the high-availability bare metal for external service;
calling an installation component, and performing system installation on two bare metals through PXE (pre-start execution environment) according to user requirements;
after the bare metal system is installed (the bare metal is still on an underley network at the moment), logging in to a bare metal service through SSH, carrying out password and network initialization configuration of the bare metal, and simultaneously, pulling high-availability agents for installation and deployment;
the control plane issues configuration to the uplink switch, and the bare metal is mapped into the overlay network through network virtualization technologies such as VXLAN, BGP EVPN and the like.
After the bare metal is switched to the overlay network, the agent can automatically report the health information of the bare metal to the high-availability module. After receiving the health report request, the high-availability module randomly selects one device and issues a configuration task of the floating IP in a response message of the request. After the Agent receives the configuration, the floating IP configuration is automatically completed, and the sub-interface of the bond0 network card is configured at present. To this end, the client can access the service provided by the bare metal through the floating IP.
