1、Hue的安装
（1）解压hue的安装包。
cdh]$ tar -zxf hue-3.7.0-cdh5.3.6-build.tar.gz -C /opt/app/
（2）编辑配置文件/opt/app/hue-3.7.0-cdh5.3.6/desktop/conf/hue.ini。

[desktop]

# 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<qW5o

# Webserver listens on this address and port
http_host=hadoop-senior.ibeifeng.com
http_port=8888

# Time zone name
（3）进入/opt/app/hue-3.7.0-cdh5.3.6目录，运行Hue。
hue-3.7.0-cdh5.3.6]$ build/env/bin/supervisor

（2）编辑配置文件/opt/cdh-5.3.6/hadoop-2.5.0-cdh5.3.6/etc/hadoop/core-site.xml，添加如下属性。

<property>
<name>hadoop.proxyuser.hue.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.groups</name>
<value>*</value>
（3）编辑配置文件/opt/app/hue-3.7.0-cdh5.3.6/desktop/conf/hue.ini。
HDFS部分配置如下：

[hadoop]

[[hdfs_clusters]]
# HA support by using HttpFs

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

（3）编辑配置文件/opt/app/hue-3.7.0-cdh5.3.6/desktop/conf/hue.ini。

[beeswax]

# Host where HiveServer2 is running.
# If Kerberos security is enabled, use fully-qualified domain name (FQDN).
hive_server_host=hadoop-senior.ibeifeng.com

# Port where HiveServer2 Thrift server runs on.
hive_server_port=10000

# Hive configuration directory, where hive-site.xml is located
hive_conf_dir=/opt/cdh-5.3.6/hive-0.13.1-cdh5.3.6/conf

# Timeout in seconds for thrift calls to Hive service
server_conn_timeout=120
4、Hue结合RDBMS
（1）编辑配置文件/opt/app/hue-3.7.0-cdh5.3.6/desktop/conf/hue.ini。

[librdbms]
# The RDBMS app can have any number of databases configured in the databases
# section. A database is known by its section name
# (IE sqlite, mysql, psql, and oracle in the list below).

[[databases]]
# sqlite configuration.
[[[sqlite]]]
# Name to show in the UI.
nice_name=SQLite

# For SQLite, name defines the path to the database.
name=/opt/app/hue-3.7.0-cdh5.3.6/desktop/desktop.db

# Database backend to use.
engine=sqlite

# Database options to send to the server when connecting.
# https://docs.djangoproject.com/en/1.4/ref/databases/
## options={}

# mysql, oracle, or postgresql configuration.
[[[mysql]]]
# Name to show in the UI.
nice_name="My SQL DB"

# For MySQL and PostgreSQL, name is the name of the database.
# For Oracle, Name is instance of the Oracle server. For express edition
# this is ‘xe‘ by default.
name=test

# Database backend to use. This can be:
# 1. mysql
## options={www.fengshen157.com}

# mysql, oracle, or postgresql configuration.
[[[mysql]]]
# Name to show in the UI.
nice_name="My SQL DB"

# For MySQL and PostgreSQL, name is the name of the database.
# For Oracle, Name is instance of the Oracle server. For express edition
# this is ‘xe‘ by default.
name=test

# Database backend to use. This can be:
# 1. mysql
# 2. postgresql
# 3. oracle
engine=mysql

# IP or hostname of the database to connect to.
host=hadoop-senior.ibeifeng.com

# Port the database server www.yongshiyule178.com is listening to. Defaults are:
# 1. MySQL: 3306
# 2. PostgreSQL: 5432
# 3. Oracle Express Edition: 1521
port=3306

# Username to authenticate with when connecting to the database.
user=root

# Password matching the username www.mhylpt.com/ o authenticate with when
# connecting to the database.
password=123456

5、Hue结合Oozie
（1）编辑配置文件/opt/app/hue-3.7.0-cdh5.3.6/desktop/conf/hue.ini。

###########################################################################
# Settings to configure liboozie
###########################################################################

[liboozie]
# The URL where the Oozie service runs on. This is required in order for
# users to submit jobs. Empty value disables the config check.
oozie_url=http://hadoop-senior.ibeifeng.com:11000/oozie

# Requires FQDN in oozie_url if enabled
## security_enabled=false

# Location on HDFS where the workflows/coordinator are deployed when submitted.
remote_deployement_dir=/user/beifeng/examples/apps

###########################################################################
# Settings to configure the Oozie app
###########################################################################

[oozie]
# Location on local FS where the examples are stored.
local_data_dir=/opt/cdh-5.3.6/oozie-4.0.0-cdh5.3.6/examples

# Location on local FS where the data for the examples is stored.
sample_data_dir=/opt/cdh-5.3.6/oozie-4.0.0-cdh5.3.6/examples/input-data

# Location on HDFS where the oozie examples and workflows are stored.
remote_data_dir=/user/beifeng/examples/apps

# Maximum of Oozie workflows or coodinators to retrieve in one API call.
oozie_jobs_count=100

# Use Cron format for defining the frequency of a Coordinator instead of the old frequency number/unit.
enable_cron_scheduling=true
（2）编辑配置文件/opt/cdh-5.3.6/oozie-4.www.dasheng178.com 0.0-cdh5.3.6/conf/oozie-site.xml，将oozie的共享库改为oozie用户，而不是beifeng用户。

<property>
<name>oozie.service.WorkflowAppService.system.libpath</name>
<value>/user/oozie/share/lib</value>
<description>
System library path to use for workflow applications.
This path is added to workflow application www.tianjiuyule178.com if their job properties sets
the property ‘oozie.use.system.libpath‘ to true.
</description>
</property>

（3）将oozie的共享库上传。
oozie-4.0.0-cdh5.3.6]$ bin/oozie-setup.sh sharelib create -fs hdfs://hadoop-senior.ibeifeng.com:8020 -locallib oozie-sharelib-4.0.0-cdh5.3.6-yarn.tar.gz
（4）启动oozie服务。
oozie-4.0.0-cdh5.3.6]www.huayiyul.com/$ bin/oozied.sh start

6、启动Hue
进入目录/opt/app/hue-3.7.0-cdh5.3.6/，执行如下命令：
hue-3.7.0-cdh5.3.6]$ build/env/bin/supervisor
也可执行完每步后分别重新启动。
