CN105607903A - Openstack component deployment method - Google Patents

Abstract

The present invention relates to the technical field of cloud computing, and in particular to a method. The method disclosed by the present invention comprises: on a certain node A, sequentially installing a virtual environment package and a public dependency software package, creating a virtual environment, executing a component installation command, and carrying out initial configuration on a component; copying a virtualization environment on the node A to a node B; and carrying out initial configuration on a node B component. The method disclosed by the present invention realizes mutual isolation of the dependency environment of each component, solves the problem of dependency conflict due to software deployment, effectively improves deployment flexibility and reduces time overhead, and can be used for Openstack component deployment.

Description

A kind of method of disposing openstack assembly

Technical field

The present invention relates to cloud computing technology field, particularly a kind of method of disposing openstack assembly.

Background technology

OpenStack is a cloud computing management platform project of increasing income, and is combined by several main assembliesComplete specific works. OpenStack mainly contains following assembly: nova (calculating), swift (object storage clothesBusiness), Glance (mirroring service), keystone (mirroring service), Horizon (UI service), Cinder (pieceStores service), Ceilometer (monitor service), ironic (deployment services). Each assembly is relatively independent,The framework of loose coupling is a complicated and job consuming time so dispose each assembly of openstack. For thisThe current industry of the situation of kind has the scheme of the following automatic deployment:

1) devstack scheme, directly git source code, installs, and object is to allow the developer can be quickBuild an environment, but be not suitable for production environment.

2) rdo scheme, RDO disposes each assembly based on puppet, supports single node or multinode to dispose,Be very easy to use in operating system at Redhat

3) fule scheme, is supported in ubuntu and centos upper by web interface configurations deploymentOpenstack should be Openstack deployment tool the most intuitively at present. Support automatically to send outNow dispose node, and dispose OpenstackHA, Openstack is done to health examination etc.

Scheme with deploy meets most demand substantially, but the assembly of openstack is at full speed sending outExhibition, there will be a kind of situation, and user is in the urgent need to a new function, and this new function can only be in new versionThis openstack assembly just can provide, if adopt 3 kinds of schemes above, because can not solve different editionsRely on the problem of conflict, need whole upgrade components, potential risk is larger.

Summary of the invention

The technical problem that the present invention solves is to provide a kind of method of the openstack of deployment assembly, realizes eachThe dependence environment of assembly is isolated mutually, the problem of the dependence conflict that solution deployment of components brings, effectively lifting partsAdministration's flexibility and reduction time overhead.

Solution of the present invention rushes to the technical scheme of stating technical problem:

Described method is, at certain node A, virtual environment bag, public dependent software package are sequentially installed, woundBuild a virtual environment, executive module installation order, assembly initialization configuration; Then virtual by node AChange environment and be copied to another Node B; This Node B assembly initialization configuration.

Described node A, is often referred to the station server under openstack cluster, and on server, install and calculate,Storage or networking component.

Described installation virtual environment bag, refers to the virtual environment storehouse virtualenv of a kind of python, virtualenvEffect be that multiple Python are separate, are independent of each other for creating independently Python environment;

Described function relies on bag, refers to Mysql database and message queue rabbitmq, and message queue is used forMessage communication between assembly;

Described assembly installation order refers to that assuring grooming tool setuptools by Python installs;

Described initial configuration refers to, according to the configuration of Openstack, document is installed, and is organized into an installation componentScript, support rapid configuration assembly.

The inventive method has realized the dependence environment of the each assembly of openstack isolates mutually, has solved assembly portionThe problem of the dependence conflict that administration brings, has effectively promoted deployment flexibility and has reduced time overhead.

Brief description of the drawings

Below in conjunction with accompanying drawing, the present invention is further described:

Fig. 1 is flow chart of the present invention.

Detailed description of the invention

As shown in Figure 1, the present invention includes following steps:

1, node A installs virtual environment bag;

#yuminstallpython-virtualenv.noarch

2, node A installs public dependent software package;

#yuminstallrabbitmq-server

#systemctlenablerabbitmq-server.service

#systemctlstartrabbitmq-server.service

#rabbitmqctlchange_passwordguestRABBIT_PASS

3, node A creates a virtual environment;

#virtualenvheat-env

4, node A executive module installation order;

It is example that heat assembly is installed

#cdheat-env/

#source./bin/activate

#cd/opt/stack/heat

#pythonsetup.pyinstall

5, node A assembly initialization configuration;

Heat configuration script is as follows;

openstack-config--set/etc/heat/heat.confdatabaseconnection

Mysql: cut _ DBPA of //heat:HEA point controller/heat

Openstack-config--set/etc/heat/heat.confDEFAUL cuts rpc_backendrabbit

Openstack-config--set/etc/heat/heat.confDEFAUL cuts rabbit_hostcontroller

Openstack-config--set/etc/heat/heat.confDEFAUL cuts rabbit_passwordRABBI and cuts _ PA point
