The automatic application deployment on the cloud platform can meet the requirement that a cloud platform user issues an automatic software installation tool and an automatic application configured complete application according to a certain application template format, so that application services required by the user can be provided in time. The automatic application deployment provided by the current mainstream cloud platform is realized by defining each automatic deployment template in advance, and when a user needs to deploy one application, only one template needs to be selected to release the application. The mode can generally meet the requirements of general users; but there may be problems when an application is a multi-role application cluster. The application templates specified by the user in advance are generally fixed, and the cluster roles of the applications automatically issued by utilizing the templates are also fixed; if a cluster needs to add a new cluster role later in the use process, only a virtual machine can be manually created and manually added, and the advantage of automatic deployment of the application is lost by the way of manually adding the cluster role.

Detailed Description
The invention provides a method for issuing an application cluster by multi-template combination, which realizes that the same application can be issued by a plurality of templates in a template combination mode, and the application issued by the subsequent template is used as the cluster extension of the first template application.
Fig. 1 is a flowchart of a method for publishing an application cluster by combining multiple templates according to an embodiment of the present invention. The following describes specific implementation of each process by taking the spark cluster as an example.
(1) Respectively manufacturing cloud server mirror images of the master template and the slave template and uploading the mirror images to the cloud platform
Making master mirror image and slave mirror image of large data processing spark cluster, implementing required software tools such as scale-2.11.7. tgz, spark-1.6.0-bin-hadoop2.6.tgz in mirror image, and making initial installation configuration. If the scala software is installed, the following steps are performed:
uploading the downloaded file scala-2.11.7.tgz to the mirror/home/Hadoop/spark/directory, and running a decompression command: tar zxvf scala-2.11.7. tgz; the bash _ profile adds the following information:
vim～/.bash_profile
# Add the following
export SCALA_HOME＝/home/hadoop/spark/scala-2.11.7
export PATH＝$PATH：$SCALA_HOME/bin
After the save exits, source-/. bash _ profile is run to take effect.
Test if Scala was successfully installed: scale-version
And submitting the manufactured cluster master mirror image and slave mirror image to a cloud platform mirror image storage system for later application template creation and selective use.
(2) Cloud platform tenant creation private intranet
The cloud platform tenant logs in the cloud platform to create a private intranet of the cloud platform tenant for later creation of an application template for selective use, and different users can share the same intranet.
(3) Cloud platform tenant utilizes master template mirror image and created intranet to establish master template
In the process of creating the master template, a designated master mirror image is mainly selected, and then an automatic installation configuration script is set for the master mirror image, wherein the automatic configuration script corresponding to a spark master mirror image is as follows:
#！/bin/bash
SPARK_HOME＝/home/hadoop/spark/spark-2.2.0-bin-hadoop2.7
var＝`LC_ALL＝C ifconfig|grep’inet addr：’|grep-v’127.0.0.1’
cut-d：-f2|awk’{print$1}’`
#sed-i’s，20.251.55.190，’${var}’，g’/etc/hosts
sed-i’s，10.10.10.220，’${var}’，g’/etc/hosts
sh${SPARK_HOME}/sbin/start-master.sh
the script is used for acquiring the current intranet IP (such as 10.10.10.238) of the virtual machine created by using the master mirror image and replacing the original IP10.10.10.220 of the mirror image template in the/etc/hosts; sh script starts master service of spark.
(4) Cloud platform tenant selection master template creation master application
The tenant selects the created master application template and sets the name of the application, the related description information and the like to automatically release a master application.
(5) Cloud platform tenant creates slave template by using slave template mirror image and created intranet
In the slave template creating process, a designated slave image also needs to be selected, and then an automatic installation configuration script is set for the slave image, particularly, a master application needs to be designated, where an intranet IP of a cloud server in the master application is used as a parameter for replacement, and an automatic configuration script corresponding to a master slave image is as follows:
#！/bin/bash
SPARK_MASTER_IP＝$1
SPARK_HOME＝/home/hadoop/spark/spark-2.2.0-bin-hadoop2.7
sed-i’s，20.251.55.190，’${SPARK_MASTER_IP}’，g’/etc/hosts
ip＝`LC_ALL＝C ifconfig|grep’inet addr：’|grep-v’127.0.0.1’|cut-d：-f2|awk’{print$1}’`
#name＝`hostname`
cat>>/etc/hosts<<EOF
${ip}spark004
$ip$name
EOF
sh${SPARK_HOME}/sbin/start-slave.sh spark：//spark001∶7077
(6) the cloud platform tenant selects the slave template and specifies the master template to create the slave application.
Selecting a slave template, setting application name, description information and the like, designating relevant parameters (such as intranet IP (Internet protocol) of a cloud server of the master template) corresponding to the master template in the slave template, and starting an automatic application release process of the slave template; and after the successful release, the slave template application automatically joins the master template application cluster.
In particular, the publication from the template may be expanded later with the use of the application cluster.
The embodiments described above are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, those skilled in the art can obtain solutions without substantial creation, and all of them fall within the protection scope of the present invention.
