Description

Configuration management server and method for automatically constructing the shape of multiple hosts

The present invention relates to a configuration management server and method for automatically constructing configurations of a plurality of hosts. More particularly, the present invention relates to a construction task of constructing hosts in a predetermined shape in a network system to which a plurality of hosts are connected. An invention relates to a configuration management server and method for supporting and managing the configuration of hosts.

In a network where multiple hosts are connected, a system that assigns network addresses to hosts and remotely installs an operating system includes a DHCP server and a TFTP server. The DHCP server is a server for dynamically assigning IP addresses to hosts using a DHCP (Dynamic Host Configuration Protocol) protocol. The DHCP server assigns IP addresses corresponding to MAC addresses of hosts according to individual requests of the hosts. The user of the host assigned the IP address requests a boot-loader image from the TFTP server, and the administrator of the TFTP server transmits the boot loader image according to the user's request. The user of the host who received the boot loader image selects the remote installation of the operating system, receives the installation file of the operating system from the TFTP server, and installs it. The TFTP server uses the Trivial File Transfer Protocol (TFTP) protocol to remotely provide operating system installation files to hosts.

In such a remote operating system installation system requires manual instructions from users and administrators, and large scale host implementation is inefficient because it takes a lot of time for simple iterations. In addition, since the administrator cannot know the MAC addresses of the hosts connected to the network in advance, the DHCP server has a disadvantage of assigning IP addresses in response to individual requests of a plurality of hosts. Host users are inefficient because they manually configure the host environment after installing the operating system.

On the other hand, when a part is said to "include" a certain component, it means that it may further include other components, without excluding other components unless otherwise stated.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, the network switch 110 according to the present invention includes a connection information collecting unit 111, a connection information providing unit 112, and a connection port 113. The

hosts

121, 122, 123 and the configuration management server 130 are connected to the connection port 113.

The connection information collecting unit 111 may include connection ports corresponding to MAC address information “A”, “B”, “C” and MAC address information of the

hosts

121, 122, and 123 connected to the connection port 113 of the network switch ( 113) Gather information. For example, the connection information collecting unit 111 may utilize a MAC table 114 that corresponds to MAC addresses of hosts for each connection port.

The connection information collector 111 updates the connection information of the

hosts

121, 122, and 123 that have transmitted and received the inbound or outbound packet. The configuration management server 130 may broadcast the packet for the PING test or ARP request continuously so that the connection information collecting unit 111 may update the connection information of the

hosts

121, 122, and 123.

The connection information provider 112 provides the configuration management server 130 with the information collected by the connection information collector 111. The connection information provider 112 may use an application programming interface (API) for access of the configuration management server 130.

The administrator may organize the physical binding between the connection port 113 of the network switch 110 and the

hosts

121, 122, and 123 according to a predetermined rule. For example, host 1 121 is connected to connection port 1 113a and host 2 122 is connected to connection port 2 113b in sequence.

Referring to FIG. 2, the configuration management server 210 includes a shape information registration unit 211, a connection information acquisition unit 212, an address mapping unit 213, and an automation support unit 214. The configuration management server 210 is connected to the network switch 110 and the DHCP server 220.

The shape information register 211 receives shape information including a plurality of IP addresses from an administrator. The IP address entered by the administrator becomes the basis of the IP address assigned to the hosts 120. For example, if an administrator wants to assign a private IP address to a C class and assign it to a host, a series of IP addresses can be input by specifying a range as the lowest and highest IP addresses of the C class.

The configuration information is information about the configuration of the host to be constructed by the administrator and includes the hardware and software information of the host along with the IP address. For example, the shape information may be hardware and software information, and may include operating system information, kernel information, manufacturer name, product number, manufacturing number, processor information, network interface information, or disk information of hosts to be constructed by the administrator.

In addition, the shape information register 211 may receive the shape information of the host for each host connected to the network switch 110. The host may use the configuration management agent as an API for providing the configuration information to the configuration management server 210. The configuration management agent is installed by transmitting a remote TFTP server to each host to be described later. If the administrator inputs new configuration information or the user of the individual host changes the shape of the host, the configuration information of the host provided by the configuration management agent is inconsistent with the configuration information input by the configuration information registration unit 211. Therefore, the host can be rebuilt or maintained at the discretion of the administrator.

The connection information acquisition unit 212 receives the MAC addresses of the hosts 120 and the connection port 113 associated with the MAC addresses from the network switch 110. The connection port 113 information includes a connection port number. An example of the information received from the network switch 110, see FIG.

The address mapping unit 213 performs MAC addresses of the hosts 120 based on the MAC address information of the hosts 120 acquired by the connection information acquisition unit 212 and the shape information received by the shape information registration unit 211. And map IP addresses. The address mapping unit 213 may map the MAC address and the IP address in order from the lowest IP address according to the number order of the access ports 113 where the hosts 120 are located. For example, host 1 121 has MAC address "A" in PORT1 133a, host 2 122 has MAC address "B" in PORT2 133b, and MAC address "C" in PORT3 133c. Assuming that the host 3 (123) having each of the two connected to each other, and the configuration information registration unit 211 receives 255 IP addresses consecutive from the lowest IP address "10.20.1.1", "MAC: A / IP Map the MAC address to the IP address: "10.20.1.1", "MAC: B / IP: 10.20.1.2" and "MAC: C / IP: 10.20.1.3".

In addition, the address mapping unit 213 may combine the shape information of the host input by the administrator to the mapping information of the MAC addresses and the IP addresses. The information combining the mapping information and the shape information is used by the DHCP server 220 to allocate IP addresses to the hosts, and the TFTP server to install an operating system. 6 illustrates an example of combining shape information and mapping information.

The automation support unit 214 provides the DHCP server 220 with mapping information of the host's MAC addresses and IP addresses. The DHCP server 220 creates a DHCP configuration data 720 based on the provided mapping information, and actually assigns IP addresses to hosts based on the DHCP configuration data 720. The automation support unit 214 may automate the process of providing mapping information to the DHCP server 220 and creating the DHCP configuration data 720 by using a system management automation tool. "Chef" programming (710) and automatically generated "dhcpd.conf" file when using open source "Chef" as a system management automation tool to create DHCP configuration data 720 "dhcpd.conf" of DHCP server See FIG. 7 for an example.

In addition, the automation support unit 214 may be configured to support a PXE (Pre-boot eXecution Enviroment) environment of the host. In this case, the automation support can use the Intelligent Platform Management Interface (IPMI) as an interface for controlling hosts with PXE boot. The IPMI interface includes the "POWER ON", "POWER OFF" and "RESET" functions of the hosts, so that the hosts can be remotely booted by sending network boot packets through the IPMI tool.

Referring to FIG. 3, the host shape building automation system according to the present invention includes a network switch 310, a shape management server 320, a DHCP server 330, a TFTP server 340, and an HTTP server 350. . The configurations of the network switch 310 and the configuration management server 320 refer to FIGS. 1 and 2, respectively.

The network switch 310 is connected to the hosts 360, and provides the configuration management server 320 with information associated with the MAC addresses of the hosts 360 and the connection port information of the network switch 310. .

The configuration management server 320 remotely boots the corresponding hosts through the IPMI tool for the hosts having the PXE boot function, and the IP input by the administrator to the MAC addresses of the hosts 360 received from the network switch 310. Map the address. The mapping information is provided to the DHCP server 330 using a system management automation tool, and the DHCP server 330 automates the generation of the DHCP configuration data 720 to actually assign IP addresses to the hosts. The main contents of the DHCP configuration data 720 include "Dynamic or fixed IP address allocation scheme", "MAC address" and "IP address". An example of the DHCP configuration data 720 is shown in FIG. 7. Examples of system management automation tools include "Chef" or "Puppet". In addition, the configuration management server 320 monitors the TFTP server 340 and the HTTP server 350 together with the DHCP server 330 using a system management automation tool, and based on the configuration information input from the administrator TFTP server ( 340 may automate the generation of TFTP configuration data including software image information to be provided to hosts 360 and TFTP configuration data including software configuration information to be provided to hosts 360 by HTTP server 350. have.

The DHCP server 330 receives the mapping information of the MAC addresses and the IP addresses and allocates the IP addresses to the hosts 360 based on the automatically generated DHCP configuration data 720. The DHCP server 330 allocates a fixed IP address collectively to a plurality of hosts according to a result of the configuration management server 320 mapping the IP addresses by MAC addresses of the hosts 360.

In addition, the DHCP server 330 may guide the next step of acquiring the IP address to the host to which the IP address is assigned based on the setting contents of the DHCP configuration data 720. For example, if you add "next-server 192.168.10.2; filename" pxelinux.0 ";" to the "/etc/dhcpd.conf" file, the host has an IP address of "192.168.10.2" since the host was assigned an IP address. Access the server and receive the "pxelinux.0" boot loader. In the present invention, "next-server 192.168.10.2" means the TFTP server 340.

The TFTP server 340 remotely transmits the software installation file to the hosts 360 using the Trivial File Transfer Protocol (TFTP) protocol. The TFTP server 340 selects a software installation file based on the TFTP configuration data automatically generated by the system management automation tool of the configuration management server, and provides the software installation file to the hosts 360. For example, when the administrator wants to virtualize the hosts, the administrator may include information of the virtualization hypervisor "XEN" in the configuration information input to the configuration management server 320. The system management automation tool "Chef" of the configuration management server 320 generates TFTP configuration data to provide "XEN" to the hosts. The TFTP server 340 transmits the installation file of "XEN" to the IP addresses assigned to the hosts based on the generated TFTP configuration data.

HTTP server 350 remotely provides software configuration information to hosts 360 using HyperText Transfer Protocol (HTTP). The software configuration information provided to the hosts 360 refers to configuration information on software installed by the TFTP server provided to the hosts 340, and is generated using a system management automation tool of the configuration management server 320. Based on the configured HTTP configuration data.

If the user inputs predetermined configuration information to the configuration management server through the above-described process, the IP address allocation, operating system installation, and configuration of the installed operating system can be automated.

Referring to FIG. 4, first, the configuration management server 320 receives configuration information about hosts from an administrator (S401). The shape information is information about a shape to be built in the hosts and includes a plurality of IP addresses.

Configuration management server 320 remotely boots the host having a PXE boot function (S402).

The configuration management server 320 obtains MAC address information of hosts from the network switch (S402). Access port information associated with MAC addresses can be obtained together. For example, receiving MAC table information from the network switch.

The configuration management server 320 maps the IP addresses included in the configuration information and the MAC addresses of the acquired hosts (S403). The configuration information input by the administrator together with the mapping information of MAC addresses and IP addresses can be combined and recorded for each connection port.

The configuration management server 320 provides mapping information of MAC addresses and IP addresses of the hosts to the DHCP server (S404).
