Abstract

The invention provides a method for automatically quickly deploying NIS (network information service). A deployer only needs to arrange all scripts and files (six scrip files and two configuration files) required by deployment onto management nodes, write host names of all nodes (management nodes and computing nodes) into a host file, write NIS domain names (namely domain names) into an nis-domain file and operates install.sh by root on the management nodes, and the NIS environment deployment of all nodes can be completed after root passwords are input, and can be still available at the next starting-up.

Description

The method of a kind of automated quick deployment network information service NIS

Technical field

The present invention relates under the Linux cluster environment, to the deployment of NIS (network information service).Be specifically related to automated quick deployment based on the NIS (network information service) of shell script and expect automatic answer function.The method of specifically a kind of automated quick deployment network information service NIS.

Background technology

High-performance calculation (HPC) is mostly based on (SuSE) Linux OS; Under the Linux cluster environment; It is the system that all machines provide the network information in the network that NIS (Network Information Service) is one, comprises user name, password, master catalogue, group information etc.If certain user's user name and password have been kept in the NIS password database, NIS allows this user to have in any operation in the middle of the network on the machine of NIS CLIENT PROGRAM to land.This makes whole network look like an autonomous system, and identical account number is arranged on all main frames.In the AD of Windows (Active Directory), this is called as " account's roaming ".So, under the Linux cluster environment, always have the existence of NIS (network information service).

Traditional dispositions method is to dispose NIS Server end earlier; Dispose NIS Client end more one by one, this method is feasible when the node number is less, but under hundreds of node situation; The method will consume a large amount of working times, does the too many duplication of labour.

The present invention is exactly the problem of under extensive Linux cluster environment, NIS (network information service) being disposed in order to solve.The present invention is based on shell script and expect automatic answer function, can realize NIS (network information service) environment under the extensive Linux cluster environment of full-automatic, quick, easy deployment.

Summary of the invention

The objective of the invention is to dispose automatically, fast NIS (network information service) environment under the cluster environment, the method for a kind of automated quick deployment network information service NIS is provided.

The objective of the invention is to realize, be placed on the management node, the host name of all management nodes and computing node is write among the hostfile disposing required script and file by following mode; Domain name Nisdomain name is written in the nis_domain file; On management node, move install.sh with root user, behind the input root password, the network information service NIS environment of promptly accomplishing at all nodes maps out the work; And it is still effective after start next time

Concrete job step is following:

The first step is disposed required file with all, comprises that 6 script files and 2 configuration files are put under the same catalogue on the management node;

Second step write the host name of all nodes in hostfile, write management node earlier, write computing node again; In nis_domain, write the domain name of cluster;

The 3rd step, use root user to move the install.sh file, and according to prompting input root password;

In the 4th step, the install.sh script can call ssh_conf1.exp, ssh_conf2.exp, these three auto answer scripts based on expect of ssh_conf3.exp automatically, realizes the trust visit of the direct ssh of all nodes;

In the 5th step, the install.sh script then can call mu_conf.exp automatically, accomplishes the configuration effort of management node end, i.e. the configuration task of NIS_Server end;

The 6th the step, the install.sh script then can call cu_conf.exp automatically, accomplishes all computing nodes, promptly NIS_client hold configuration effort;

In the 7th step, behind the above all working of correct completion, the install.sh script can point out cluster NIS to dispose completion, normally uses the NIS function this moment.

The invention has the beneficial effects as follows: what the deployer need do only is that all are disposed required script and file (6 script files; 2 configuration files) be placed on the management node; The host name of all nodes (management node and computing node) is write among the hostfile; Nisdomain name (being domain name) is written in the nis_domain file, on management node, moves install.sh, behind the input root password with root user; NIS (network information service) environment that can accomplish at all nodes maps out the work, and still effective after start next time.

Embodiment

Explanation at length below with reference to Figure of description method of the present invention being done.

The objective of the invention is to dispose automatically, fast NIS (network information service) environment under the cluster environment.Concrete job step of the present invention is following:

The first step is disposed required file (6 script files, 2 configuration files) with all and is put under the same catalogue on the management node;

Second step write the host name of all nodes in hostfile, write management node earlier, write computing node again; In nis_domain, write the domain name of cluster, like TS10K;

In the 3rd step, use root user to move the install.sh file.And according to prompting input root password;

In the 4th step, the install.sh script can call ssh_conf1.exp, ssh_conf2.exp, these three auto answer scripts based on expect of ssh_conf3.exp automatically, realizes the trust visit of the direct ssh of all nodes;

In the 5th step, the install.sh script then can call mu_conf.exp automatically, accomplishes the configuration effort of management node end, i.e. the configuration task of NIS_Server end;

The 6th the step, the install.sh script then can call cu_conf.exp automatically, accomplishes all computing nodes, promptly NIS_client hold configuration effort;

In the 7th step, behind the above all working of correct completion, the install.sh script can point out cluster NIS to dispose completion, and can normally use the NIS function this moment.

Embodiment

It is 2 parts that the method for the automated quick deployment network information service of the present invention, the network architecture are divided into: storage networking and computational grid, wherein:

Storage networking uses 8GB FC optical fiber switch, adopts the memory device of FC SAN framework, divides a plurality of LUN, maps directly to management node and uses.

Computational grid adopts the Infiniband switch, and the HCA through IB cable collocation server links and receives computing node (d1/dn).Adopt IB over IP communication mechanism, realize internodal express network communication.

Be exemplified below:

Hardware environment: management node: 1

Computing node: 8

Every node memory 8GB

Every node check figure: 12 cores

Cpu frequency: 2.66GHz

Network connects: Infiniband QDR

1) in hostfile, writes management node host name and whole computing node host name;

2) in nis_domain, write the domain name of cluster;

3) on management node, move install.sh with the root identity, the root password is 111111, accomplishes configuration effort;

4) when seeing NIS Configuration is COMPLETE prompting, configuration all completion are described;

5) check management node and computing node, all nodes are all normally opened the NIS related service, and are set to the self-starting of starting shooting;

6) accomplish whole configurations of NIS, can normally use, and all configuration take-effectives when guaranteeing the next time start.
