Fig. 3 shows a flowchart of a server cluster deployment method 300 according to an exemplary embodiment of the present invention. The instruction execution method 300 in the present invention is suitable for being executed in a server, and is further suitable for being executed in the server 140 shown in fig. 1, wherein the server 140 includes a server component library, and the server component library includes a plurality of server version server component sets. As the server cluster environment is continuously updated, the server components included in the server cluster environment are continuously enriched and updated. Therefore, the server 140 is pre-constructed with a server component library, which includes different versions of server component sets, each including one or more server components, and the types and versions of the included server components may be different from each other.
As shown in FIG. 3, the server cluster deployment method 300 begins with step S310, configuring node attributes of the servers and remote servers connected to the servers. When the node attributes of the server and the remote server are configured, the operating system is installed in the server, and the server can display the configuration interface by installing the operating system in the server, so that the configuration process can be conveniently operated according to the configuration interface. The present invention does not limit the type of operating system installed in the server. According to one embodiment of the invention, a linux operating system, including but not limited to Centos7, RedHat7, Syxin operating system 1000c, etc., may be installed in the server.
The configuration interface is then rendered and displayed according to the operating system. The configuration interface is an interface for facilitating a user to configure the node attributes of the server and the remote server. According to an embodiment of the present invention, the configuration interface may be rendered and presented through entering the configuration port through the browser by running the browser on the operating system and setting the configuration port, or the device may be directly run in the operating system to render and present the configuration interface by pre-constructing the server cluster deployment device, and the implementation manner of the configuration interface is not limited in the present invention.
After the configuration interface is presented to the user, the user may configure the node attributes of the server and the remote server in the configuration interface. And receiving the selection of the node attributes of the server and the remote server from the configuration interface by the user, and configuring the node attributes of the server and the remote server.
When the node attributes of the server and the remote server are configured, the IP address and the host name of the server and the IP address and the host name of the remote server connected with the server are set, and the node attributes are set according to the IP address and the host name of each server.
The server cluster is constructed by the server and the remote server, and can be used for building a cloud computing platform. According to one embodiment of the invention, a server cluster constructed by using a server and a remote server can be used for building an OpenStack cloud computing management platform project.
OpenStack is an open source code project that is authorized with an Apache license (a free software license issued by the Apache software foundation). Openstack is accomplished by a combination of a number of major components. Mainly helping Service providers and enterprises to realize cloud Infrastructure services (Infrastructure as a Service) similar to Amazon ec2 and S3 internally. Openstack includes a collection of Openstack computation (code number Nova), Openstack object store (code number Swift), Openstack local store (code number Cinder), Openstack web service (code number Neuton), Openstack authentication service (code number Keystone), Openstack mirror service (code number Glance). OpenStack also provides an operating platform, or toolkit, for orchestrating the cloud.
Therefore, the server cluster constructed in the invention needs servers with various node attributes. The server or the remote server can have various node attributes, the node attributes comprise a computing node, a management node and a storage node, the types and the number of the node attributes are not limited, and developers can configure more different types of node attributes according to actual needs so as to meet the needs of constructing a server cluster.
When the node attributes of the server and the remote server are configured, the configurable node attributes of each server are provided for a user to select, and the user can select one node attribute configuration server. When the user does not perform manual configuration, the configuration can also be automatically performed by the server.
In configuring the node attributes of the server and the remote server, the configuration principle needs to be followed. The configuration principle comprises the following steps: the node attribute of at least one node in the server cluster comprises a computing node, the node attribute of at least one node comprises a management node, and the node attribute of at least one node comprises a storage node. Each server may have multiple node attributes, and assume multiple node tasks, among the servers and the connected remote servers.
According to one embodiment of the invention, when only a server is used to configure a server cluster without other remote servers connected thereto, the server has a variety of node attributes including compute nodes, management nodes, and storage nodes.
According to another embodiment of the present invention, when there is only one server and one remote server connected thereto, at least one server needs to include two or more node attributes to meet the requirements of the actual configuration server cluster.
Subsequently, step S320 is executed to obtain one or more component configuration servers from the server component library according to the node attribute of the server, so as to obtain the server node. When configuring a server node, a server version of the server needs to be set. As the server cluster environment is continuously updated, the server components included in the server cluster environment are continuously enriched and updated. Thus, the server component library in the server 140 includes different versions of server component sets, and the kind and version of the server component of each server component set may be different. Taking OpenStack as an example, on average, a release version is generated every 6 months or so, and each OpenStack release contains 40 or more components. The OpenStack version includes: austin, Bexar, Cattus, Diablo, Essex, Folsom, Grizzly, Havana, and Queens, among others.
After the server version of the server is specified, one or more components are obtained from the server component set corresponding to the server version according to the set server version and serve as the component configuration server required by the node attribute.
According to one embodiment of the invention, the server version set by the server is Havana, and the Havana server component set of the server component library comprises: the system comprises a Nova component responsible for computing services, a Glance component responsible for mirroring services, a Swift component responsible for object storage services, a Horizon component responsible for GUI services, a Keystone component responsible for identity services, a Neutron component responsible for network services, a Cinder component responsible for block storage services, a Heat component responsible for orchestration services, and a Ceilometer component responsible for metering monitoring.
If the node attribute set by the server is a computing node, pulling a Nova component configuration server in charge of computing service; if the node attribute set by the server is a storage node, pulling a Swift component responsible for the object storage service, a circle component responsible for the block storage service and a Glance component configuration server responsible for the mirror image service; and if the node attribute set by the server is the management node, pulling a Horizon component responsible for GUI service and a Keystone component configuration server responsible for identity service.
According to one embodiment of the invention, when the server version of the server in the server cluster is upgraded, the node attribute of each server node is kept consistent before and after the upgrade, and cannot be changed.
Subsequently, step S330 is executed to obtain one or more components from the server component library according to the node attribute of each remote server connected to the server to configure each remote server, so as to obtain one or more remote server nodes. When each remote server is configured, one or more components are obtained from the server component set corresponding to the server version according to the server version of the server, and the components are used as components required by the node attribute to configure the remote server. When the remote server is configured, the server version of the remote server is the same as the server version of the server, so that the server versions of all the servers in the server cluster are kept consistent.
According to one embodiment of the invention, when the server version of the server is Havana, the server versions of all remote servers connected to the server are configured to be Havana. When the remote server is configured, if the node attribute set by the remote server is a computing node, pulling a Nova component configuration server in charge of computing service; if the node attribute set by the remote server is a storage node, pulling a Swift component responsible for the object storage service, a circle component responsible for the block storage service and a Glance component configuration server responsible for the mirror image service; and if the node attribute set by the remote server is a management node, pulling a Horizon component responsible for GUI service and a Keystone component configuration server responsible for identity service.
According to one embodiment of the invention, when the remote server is configured, an operating system can be installed in the remote server, and the server component library is copied from the server to the remote server according to the IP addresses of the server and the remote server through an scp command or an ssh command. And then pulling the corresponding component according to the copied server component library at the remote server to configure the remote server. Or the operating system is not installed in the remote server, the server component library is directly copied from the server to the remote server in a pxe mode in the BIOS configuration, and the related components are started to configure the remote server.
Subsequently, step S340 is executed to construct a server cluster according to the server nodes and the one or more remote server nodes. When a server cluster is constructed according to a server node and one or more remote server nodes, at present, environmental deployment is prone to errors, deployment time is long, once errors occur in the middle of deployment, the deployment is required to be repeated, and more time is required to be consumed. Therefore, in the invention, if one or more remote server nodes have faults, fault information is provided, maintenance personnel can conveniently and quickly locate the problems, and the fault information is processed in time, so that a server cluster is normally built.
When a server cluster is constructed, if one or more remote server nodes have faults, whether node attributes of at least one node in the server nodes and normal remote server nodes comprise computing nodes is judged, if the node attributes of at least one node comprise the computing nodes, the server cluster is normally constructed, and otherwise, error information lacking the computing nodes is popped up so as to reconfigure the computing nodes. When the computing node is reconfigured, one or more servers are selected from the rest normal remote servers and servers to add the node attribute of the computing node, and the corresponding server component is pulled to be configured according to the node attribute of the computing node.
And judging whether the node attribute of at least one node in the server node and the normal remote server node comprises a management node, if the node attribute of at least one node comprises the management node, normally forming a server cluster, and if not, popping up error information lacking the management node so as to reconfigure the management node. When the management node is reconfigured, one or more servers are selected from the rest normal remote servers and servers to add the node attribute of the management node, and the corresponding server component is pulled to be configured according to the node attribute of the management node.
And judging whether the node attribute of at least one node in the server node and the normal remote server node comprises a storage node, if the node attribute of at least one node comprises the storage node, normally forming a server cluster, and if not, popping up error information lacking the storage node so as to reconfigure the storage node. When the storage nodes are reconfigured, one or more servers are selected from the rest normal remote servers and servers to add the node attributes of the storage nodes, and corresponding server components are pulled to be configured according to the node attributes of the storage nodes.
Through the judgment steps and the processing of the corresponding error information, the server cluster can be ensured to include all the server nodes of the required types when the server cluster is constructed, and the normal construction and operation of the server cluster are ensured.
