安装Hue
测试集群:hadoop101 hadoop102 hadoop103
集群配置:阿里云3台云服务器 centos7.5 2core 8Gmemory
集群框架:
hue:hadoop102
hadoop:hadoop101 hadoop102 hadoop103
hive:hadoop 101
mysql: hadoop101
zookeeper: hadoop101 hadoop102 hadoop103
kafka: hadoop101 hadoop102 hadoop103
spark: hadoop101
可直接使用编译后的hue,修改配置成自己集群配置即可
本文默认已配置好上述集群中除hue以外的所有框架
注意:结合自己的集群修相关节点配置即可
(1)在102机器上装hue,创建software文件夹,上传压缩包并解压
[[email protected] software]# unzip hue-master.zip -d /opt/module/
(2)安装环境
[[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)编译安装,编译完成后生成build文件夹
[[email protected] hue-master]# make apps
(4)修改hadoop配置文件,因为集群HA模式,所以采用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)分发配置文件
[[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配置文件,集成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)集成yarn,以下logic_name需要对应yarn-site.xml文件里的配置,注意:一定要解开HA标签前面的注释,否则会报错
[[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)集成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中创建hue库
[[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)集成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)停止集群,重启
[[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)启动hive服务
[[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)新增用户hue,并修改文件夹权限
[[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)初始化数据库
[[email protected] hue-master]# build/env/bin/hue syncdb
[[email protected] hue-master]# build/env/bin/hue migrate
(14)启动hue,注意启动的时候必须启动hive的两个服务,并且metastore和hiveserver2两个服务必须启动,10000端口占用着
[[email protected] hue-master]# build/env/bin/supervisor
(15)登录hue,执行hive sql
