安裝Hue
測試叢集：hadoop101 hadoop102 hadoop103
叢集配置：阿裡雲3台雲伺服器 centos7.5 2core 8Gmemory
叢集架構：
hue：hadoop102
hadoop：hadoop101 hadoop102 hadoop103
hive：hadoop 101
mysql: hadoop101
zookeeper: hadoop101 hadoop102 hadoop103
kafka: hadoop101 hadoop102 hadoop103
spark: hadoop101
可直接使用編譯後的hue,修改配置成自己叢集配置即可
本文預設已配置好上述叢集中除hue以外的所有架構
注意：結合自己的叢集修相關節點配置即可
（1）在102機器上裝hue,建立software檔案夾，上傳壓縮包并解壓
[[email protected] software]# unzip hue-master.zip -d /opt/module/
（2）安裝環境
[[email protected] software]# cd /opt/module/hue-master/
[[email protected] hue-master]# sudo yum install ant asciidoc cyrus-sasl-devel cyrus-sasl-gssapi cyrus-sasl-plain gcc gcc-c++ krb5-devel libffi-devel libxml2-devel libxslt-devel make mysql mysql-devel openldap-devel python-devel sqlite-devel gmp-devel
（3）編譯安裝,編譯完成後生成build檔案夾
[[email protected] hue-master]# make apps
（4）修改hadoop配置檔案，因為叢集HA模式，是以采用httpfs模式
[[email protected] hue-master]# cd /opt/module/hadoop-3.1.3/etc/hadoop/
[[email protected] hadoop]# vim hdfs-site.xml
<property>
<name>dfs.webhdfs.enabled</name>
<value>true</value>
</property>
[[email protected] hadoop]# vim core-site.xml
<property>
<name>hadoop.proxyuser.root.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.root.groups</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.groups</name>
<value>*</value>
</property>
[[email protected] hadoop]# vim httpfs-site.xml
<property>
<name>hadoop.proxyuser.root.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.root.groups</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.groups</name>
<value>*</value>
</property>
（5）分發配置檔案
[[email protected] etc]# pwd
/opt/module/hadoop-3.1.3/etc
[[email protected] etc]scp -r hadoop/ hadoop101:/opt/module/hadoop-3.1.3/etc/
[[email protected] etc]scp -r hadoop/ hadoop103:/opt/module/hadoop-3.1.3/etc/
（6）修改hue配置檔案，內建hdfs
[[email protected] hadoop]# cd /opt/module/hue-master/desktop/conf
[[email protected] conf]# vim pseudo-distributed.ini
http_host=hadoop102
http_port=8000
[[[default]]]
# Enter the filesystem uri
fs_defaultfs=hdfs://mycluster:8020
logical_name=mycluster
webhdfs_url=http://hadoop102:14000/webhdfs/v1
hadoop_conf_dir=/opt/module/hadoop-3.1.3/etc/hadoop/conf
（7）內建yarn，以下logic_name需要對應yarn-site.xml檔案裡的配置，注意：一定要解開HA标簽前面的注釋,否則會報錯
[[yarn_clusters]]
[[[default]]]
# Enter the host on which you are running the ResourceManager
## resourcemanager_host=mycluster
# 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=rm1
# Change this if your YARN cluster is Kerberos-secured
## security_enabled=false
# URL of the ResourceManager API
resourcemanager_api_url=http://hadoop101:8088
# URL of the ProxyServer API
## proxy_api_url=http://hadoop101:8088
# URL of the HistoryServer API
## history_server_api_url=http://localhost:19888
[[[ha]]]
# Resource Manager logical name (required for HA)
logical_name=rm2
# Un-comment to enable
submit_to=True
# URL of the ResourceManager API
resourcemanager_api_url=http://hadoop103:8088
# ...
（8）內建mysql
[[database]]
# Database engine is typically one of:
# postgresql_psycopg2, mysql, sqlite3 or oracle.
#
# Note that for sqlite3, 'name', below is a path to the filename. For other backends, it is the database name.
# Note for Oracle, options={"threaded":true} must be set in order to avoid crashes.
# Note for Oracle, you can use the Oracle Service Name by setting "host=" and "port=" and then "name=<host>:<port>/<service_name>".
# Note for MariaDB use the 'mysql' engine.
engine=mysql
host=hadoop101
port=3306
user=root
password=123456
# conn_max_age option to make database connection persistent value in seconds
# https://docs.djangoproject.com/en/1.9/ref/databases/#persistent-connections
## conn_max_age=0
# Execute this script to produce the database password. This will be used when 'password' is not set.
## password_script=/path/script
name=hue
在mysql中建立hue庫
[[email protected] apache-hive-3.1.2-bin]# mysql -uroot -p123456
mysql> create database hue;
## [[[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=huemetastore
# Database backend to use. This can be:
# 1. mysql
# 2. postgresql
# 3. oracle
engine=mysql
port=3306
user=root
password=123456
（9）內建hive
[beeswax]
# Host where HiveServer2 is running.
# If Kerberos security is enabled, use fully-qualified domain name (FQDN).
hive_server_host=hadoop101
# Port where HiveServer2 Thrift server runs on.
hive_server_port=10000
hive_conf_dir=/opt/module/apache-hive-3.1.2-bin/conf/
（10）停止叢集，重新開機
[[email protected] software]# /opt/module/apache-zookeeper-3.5.7-bin/bin/zkServer.sh start
[[email protected] software]# /opt/module/apache-zookeeper-3.5.7-bin/bin/zkServer.sh start
[[email protected] software]# /opt/module/apache-zookeeper-3.5.7-bin/bin/zkServer.sh start
[[email protected] software]# start-all.sh
（11）啟動hive服務
[[email protected] apache-hive-3.1.2-bin]# nohup hive --service metastore >metasotre.log>&1 &
[[email protected] apache-hive-3.1.2-bin]# nohup hive --service hiveserver2 >hiveserver2.log >&1 &
（12）新增使用者hue,并修改檔案夾權限
[[email protected] hue-master]# useradd hue
[[email protected] hue-master]# passwd hue
[[email protected] hue-master]# chown -R hue:hue /opt/module/hue-master/
（13）初始化資料庫
[[email protected] hue-master]# build/env/bin/hue syncdb
[[email protected] hue-master]# build/env/bin/hue migrate
（14）啟動hue,注意啟動的時候必須啟動hive的兩個服務,并且metastore和hiveserver2兩個服務必須啟動，10000端口占用着
[[email protected] hue-master]# build/env/bin/supervisor
（15）登入hue,執行hive sql
