The platform construction process of the education cloud of the present invention will be described by a concrete cloud platform building example below, as follows:
1, the development environment of the resource pool example of education cloud of the present invention is as follows:
Operating system: Linux ubutu server
Database: Mysql, Mongodb
Buffer memory: Redis
Development language: Php, Java
Jdk1.6 version
VMWare8.0.5 version
Hadoop-1.0.3.tar.gz software package
In addition, the requirement of hardware environment is as follows:
Network bandwidth 100M
Loaded server 1
Web server 1
MySQL server 1
Mongodb server 2
Picture servers 1
Static file server 1
Caching server 1
Resource file server 4
2, basic hardware configuration
In the specific embodiment of the invention, in the implementation process of the resource pool of the education cloud based on Hadoop, server node in HDFS environment is divided into namenode and back end (as shown in Figure 4), and wherein namenode only has one, and back end can have multiple.For MapReduce, server node is divided into JobTracker and TaskTracker, and wherein JobTracker only has one, and TaskTracker can have multiple.Wherein one is deployed as the namenode of HDFS and the JobTracker of MapReduce.Other resource file server disposition is the back end of HDFS and the TaskTracker of MapReduce.
3, SSH authenticated configuration
The Name Node (namenode) of education cloud starts and stops finger daemon on each node by SSH (Secure Shell), the object of configuration SSH uses without cryptographic public key certification, make not need to input password again during fill order between each computing node of cloud computing, therefore this step of SSH authenticated configuration key very.Configure ssh under Ubuntu first first will carry out sudo apt-get update and operate, then Auto-mounting openssh-server
$sudo apt-get install openssh-server
Then in the machine, public key is produced with order ssh-keygen.Should generate two file: id_rsa and id_rsa.pub under normal circumstances, one is private key, and one is PKI, copies on server by PKI file id_rsa.pub, then imports the user needing to log in.Root user is such as used to log in ssh server, just under importing/root/.ssh catalogue:
cat id_rsa.pub>>authorized_keys
So just can input password and just log in ssh, so just establish for the environment of active user without cryptographic acess other machines, once after successfully creating ssh keys on all machines, just can start from node deploy Hadoop.
4, the setting of cloud platform environment
Hadoop requires that the deployment bibliographic structure of Hadoop on all computing nodes is identical, and has the account of a same username.Education cloud platform of the present invention has the account of a ccea, and master catalogue is /home/ccea.It is as follows that Hadoop disposes bibliographic structure:
/ home/ccea/hadoopinstall, deposits all hadoop versions.
/ hadoop/conff, deposits all configuration files.
/ hadoop/bin, deposits all executive routines.
The environmental variance that Hadoop needs is set in the hadoop_env.sh under/home/ccea/hadoopinstall/hadoop-conf catalogue, wherein must sets JAVA_HOME variate-value.And the setting of HADOOP_HOME variable is optional, if its acquiescence of the words do not set is the parent directory of bin catalogue, setting command is as follows:
export HADOOP_HOME＝/home/ccea/Hadoopinstall/hadoop
export JAVA_HOME＝/usr/java/jdk1.6.0
Under hadoop-conf/ catalogue, open slaves file, this file is used to specify all back end,
A line Hostname:
Contain all configuration items of Hadoop in hadoop-default.xml in conf/ record, but do not allowed direct amendment! Can item inside the hadoop-site.xml under hadoop-conf/ catalogue required for definition, its value can cover the default value in hadoop-default.xml.Can customize according to actual needs.Below the hadoop-site.xml setting in this platform:
5, Hbase platform building
Hbase build process is comparatively simple, on cloud platform host node, and the conf/Hbase-env.sh under editor Hbase catalogue (referring to/home/hadoop/Hbase), thus set JAVA_HOME environmental variance.Then the conf/Hbase-site.xml under Hbase catalogue (referring to/home/hadoop/Hbase) is edited on the primary node.Then edit conf/Hbase-site.xml under Hbase catalogue (/home/hadoop/Hbase) on the primary node, its main contents are as follows:
6, application and development and deployment
Following step is mainly contained based on the education application and development of cloud and the process of deployment:
(1) Map class is realized: realize the map method in Mapper interface.
(2) Reduce class is realized: realize the reduce method in Reducer interface.
(3) run Job: a calculation task is referred to as a job in Hadoop, can arrange how to run this job by a JobConf object.
(4) design and coding: mainly contain following four steps here: 1) create Java engineering; 2) configuration compiling parameter; 3) source code is write; 4) compiling generates JAR.
(5) test run: mainly contain following four steps here: 1) configure SSH, after configuring, perform ssh localhost, confirm that your machine can connect with SSH, and do not need when connecting to input password by hand.2) distributed file system that format one is new; 3) hadoop process is started; 4) application is run.
