centos 6 安装Hue clouder5.3.6版本

Hue是Cloudera开源的一个Hadoop UI，由Cloudera Desktop演化而来。面向用户提供方便的UI用于平时的Hadoop操作中。Apache Ambari面向的是管理员，用于安装、维护集群，而不是使用集群。两者针对的是不同需求。

依赖安装：

sudo yum install krb5-devel cyrus-sasl-gssapi cyrus-sasl-deve libxml2-devel libxslt-devel mysql mysql-devel openldap-devel python-devel python-simplejson sqlite-devel

如何已经安装了mysql最好把它提前卸载了。

JDK安装

Maven和Ant安装

Hue的安装过程需要依赖于Maven和Ant，按常规方法安装Maven和Ant，配置MAVEN_HOME,ANT_HOME，并将bin目录加入PATH

• MAV（apache-maven 或者 maven3 tarball ）这里安装的是apache-maven

sudo wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo
sudo sed -i s/\$releasever/6/g /etc/yum.repos.d/epel-apache-maven.repo
sudo yum install -y apache-maven
mvn --version

下载安装hue

 sudo wget http://archive.cloudera.com/cdh5/cdh/5/hue-3.7.0-cdh5.3.6.tar.gz
 tar zxvf hue-3.7.0-cdh5.3.6.tar.gz
 cd hue-4.0.1.tgz

安装

make apps

如果编译出现问题，需要重新clean，再编译

make clean
make apps

配置Hue

Hue的配置集中在$HUE_HOME/desktop/conf/hue.ini文件，针对不同的Hadoop组件分段配置。详细配置文件参考这里。

• Hue hue.ini

  # Set this to a random string, the longer the better.
  # This is used for secure hashing in the session store.
  secret_key=jFE93j;2[290-eiw.KEiwN2s3['d;/.q[eIW^y#e=+Iei*@Mn

• Hdfs

 [[hdfs_clusters]]
    # HA support by using HttpFs

    [[[default]]]
      # Enter the filesystem uri
      fs_defaultfs=hdfs://hadoop-senior.beifeng.com:8020

      # NameNode logical name.
      ## logical_name=

      # Use WebHdfs/HttpFs as the communication mechanism.
      # Domain should be the NameNode or HttpFs host.
      # Default port is 14000 for HttpFs.
      webhdfs_url=http://hadoop-senior.beifeng.com:50070/webhdfs/v1

      # Change this if your HDFS cluster is Kerberos-secured
      ## security_enabled=false

      # Default umask for file and directory creation, specified in an octal value.
      ## umask=022

      # Directory of the Hadoop configuration
      hadoop_conf_dir=/opt/cdh5.3.6/hadoop-2.5.0-cdh5.3.6/etc/hadoop

• Yarn 配置

 [[yarn_clusters]]

    [[[default]]]
      # Enter the host on which you are running the ResourceManager
      resourcemanager_host=hadoop-senior.beifeng.com

      # The port where the ResourceManager IPC listens on
      resourcemanager_port=8032

      # Whether to submit jobs to this cluster
      submit_to=True

      # Resource Manager logical name (required for HA)
      ## logical_name=

      # Change this if your YARN cluster is Kerberos-secured
      ## security_enabled=false

      # URL of the ResourceManager API
      resourcemanager_api_url=http://hadoop-senior.beifeng.com:8088

      # URL of the ProxyServer API
      proxy_api_url=http://hadoop-senior.beifeng.com:8088

      # URL of the HistoryServer API
      history_server_api_url=http://hadoop-senior.beifeng.com:19888

      # In secure mode (HTTPS), if SSL certificates from Resource Manager's
      # Rest Server have to be verified against certificate authority
      ## ssl_cert_ca_verify=False

    # HA support by specifying multiple clusters
    # e.g.

    # [[[ha]]]
      # Resource Manager logical name (required for HA)
      ## logical_name=my-rm-name

hadoop配置

• 在hdfs-site.xml添加

  dfs.webhdfs.enabled
  true

• 在core-site.xml添加

 
　　dfs.webhdfs.enabled 
　　true 



  hadoop.proxyuser.beifeng.hosts
  *


  hadoop.proxyuser.beifeng.groups
  *

  
hadoop.proxyuser.httpfs.hosts  
*  
  
  
hadoop.proxyuser.httpfs.groups  
*  
  

注意：proxyuser 后面是Hue.ini配置文件中的server_user 值

server_user=beifeng
server_group=beifeng

启动服务

build/env/bin/supervisor

停止服务（跳过）

netstat -apn |grep 8888
kill -9 33284

第一次登陆Hue时，会有提示，随便输入用户和密码，必须要记住，这就是以后登陆Hue管理员的用户名和密码。
