hue的安装需要准备如下的前置条件
1、Java-jdk8+
2、python2.6+
3、安装时非root用户
4、另行安装maven和ant，并配置HOME
5、hue安装节点需要hadoop、hive的配置文件
6、准备一个mysql库来做hue的元数据库
第一步：前置准备中的Javajdk和python准备本简单就不演示了，maven和ant的包，解压既安装，配置好HOME测试版本无问题即可
bash
export MAVEN_HOME=/pot/apache-maven-3.3.9
export ANT_HOME=/opt/apache-ant-1.8.1
export PATH=$PATH:$MAVEN_HOME/bin
export PATH=$PATH:$ANT_HOME/bin
第二步：安装hue需要的第三方环境
bash
yum install -y asciidoc cyrus-sasl-devel cyrus-sasl-gssapi cyrus-sasl-plain gcc gcc-c++ krb5-devel libffi-devel libtidy libxml2-devel libxslt-devel make mysql mysql-devel openldap-devel python-devel sqlite-devel openssl-devel gmp-devel第三步：编译hue，首先将hue的安装包解压
bash
tar -zxvf hue-3.9.0-cdh5.14.0.tar.gz
mv hue-3.9.0-cdh5.14.0 hue3.9随后进入hue的HOME目录里面，编译hue，编译后会生成一个desktop路径，下面称为安装目录。
bash
cd hue3.9
make apps编译大概会输出很多东西，中途会卡顿，无需额外操作，大概需要3分钟左右，中途不报错就行
第四步：新建系统用户hue，将整个hue赋权给该用户，下面的操作都使用该用户操作
bash
useradd hue
passwd hue
输入密码
chown -R hue:hue /opt/hue3.9/
su hue第五步：配置desktop/conf/hue.ini文件，找到并修改如下内容，除了secret_key其他的改成你自己的，内容大概在配置文件中的20行左右
bash
secret_key=jFE93j;2[290-eiw.KEiwN2s3['d;/.q[eIW^y#e=+Iei*@Mn<qW5o
http_host=hdp3
http_port=8888
time_zone=Asia/Shanghai
第六步：运行启动命令，初步启动hue，确保服务自身没问题
bash
build/env/bin/supervisor服务正常的话，会输出如下的服务信息
bash
[hue@hdp3 hue3.9]$ ./build/env/bin/supervisor
[INFO] Not running as root, skipping privilege drop
starting server with options:
{'daemonize': False,
'host': '0.0.0.0',
'pidfile': None,
'port': 8888,
'server_group': 'hue',
'server_name': 'localhost',
'server_user': 'hue',
'ssl_certificate': None,
'ssl_certificate_chain': None,
'ssl_cipher_list': 'ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA',
'ssl_private_key': None,
'threads': 50,
'workdir': None}此时访问安装节点的8888端口，出现如下界面即可，不要着急下一步，回到安装步骤上，把前台的服务Ctrl+C关掉
第七步：Hadoop需要一些Hue的配置支持，修改hdfs-site.xml追加如下内容
xml
<!-- 打开hadoop的hdfs-web操作支持 -->
<property>
<name>dfs.webhdfs.enabled</name>
<value>true</value>
</property>
<!-- 关掉权限检查 -->
<property>
<name>dfs.permissions.enabled</name>
<value>false</value>
</property>修改core-site.xml，追加如下内容
xml
<!-- 给hue用户鉴权，告诉hadoop所有节点（*）都可以通过hue用户身份代理的形式操作hdfs -->
<property>
<name>hadoop.proxyuser.hue.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.groups</name>
<value>*</value>
</property>如果你的Hadoop是高可用的，需要在httpfs-site.xml文件中追加如下配置
xml
<!-- 所有的节点都能访问httpfs服务 -->
<property>
<name>httpfs.proxyuser.httpfs.hosts</name>
<value>*</value>
</property>
<property>
<name>httpfs.proxyuser.httpfs.groups</name>
<value>*</value>
</property>区别是：WebHDFS是HDFS内置的组件，已经运行于NameNode和DataNode中。对HDFS文件的读写，将会重定向到文件所在的DataNode，并且会完全利用HDFS的带宽。HttpFS是独立于HDFS的一个服务。对HDFS文件的读写，将会通过它进行中转，它能限制带宽占用，且hue关联高可用hdfs走的是HttpFS。
用scp同步Hadoop节点之间的配置
第八步：开始配置Hue的hdfs配置，但是这里有个问题，后面说，修改hue.ini文件，找打文件的850行左右，修改hadoop-hdfs的配置
下面的yarn配置也要改，而且注意改的时候有的要解开注释，然后yarn的HA有一些配置需要复制
txt
[hadoop]
# Configuration for HDFS NameNode
# ------------------------------------------------------------------------
[[hdfs_clusters]]
# HA support by using HttpFs
[[[default]]]
# Enter the filesystem uri
fs_defaultfs=hdfs://hdp1
# 如果是高可用的需要再次定义NN通道名
logical_name=hdp1
# Use WebHdfs/HttpFs as the communication mechanism.
# Domain should be the NameNode or HttpFs host.
# Default port is 14000 for HttpFs.
webhdfs_url=http://hdp1/webhdfs/v1
# Change this if your HDFS cluster is Kerberos-secured
## security_enabled=false
# In secure mode (HTTPS), if SSL certificates from YARN Rest APIs
# have to be verified against certificate authority
## ssl_cert_ca_verify=True
# Directory of the Hadoop configuration
hadoop_conf_dir=/opt/hadoop-2.7.2/etc/hadoop
# Configuration for YARN (MR2)
# ------------------------------------------------------------------------
[[yarn_clusters]]
[[[default]]]
# Enter the host on which you are running the ResourceManager
resourcemanager_host=hdp2
# The port where the ResourceManager IPC listens on
resourcemanager_port=8032
# 是否将作业提交到此群集，并监控作业执行情况
submit_to=True
# 如果是高可用这里要指定RN通道名
logical_name=yrc
# Change this if your YARN cluster is Kerberos-secured
## security_enabled=false
# URL of the ResourceManager API
resourcemanager_api_url=http://hdp2:8088
# URL of the ProxyServer API
proxy_api_url=http://hdp2:8088
# 历史服务器
history_server_api_url=http://hdp3:19888
# spark的历史服务器地址
spark_history_server_url=http://hdp3:18088
# In secure mode (HTTPS), if SSL certificates from YARN Rest APIs
# have to be verified against certificate authority
## ssl_cert_ca_verify=True
# HA support by specifying multiple clusters.
# Redefine different properties there.
# e.g.
[[[ha]]]
# Resource Manager logical name (required for HA)
logical_name=yrc
# Un-comment to enable
## submit_to=True
# URL of the ResourceManager API
resourcemanager_api_url=http://hdp3:8088
# URL of the ProxyServer API
proxy_api_url=http://hdp3:8088
# Enter the host on which you are running the ResourceManager
resourcemanager_host=hdp3
# The port where the ResourceManager IPC listens on
resourcemanager_port=8032第九步：配置hive，找到hue配置文件中的[beeswax]配置内容
第十步：修改hue的元数据库，首先在准备好的mysql服务中新建数据库并且赋权
bash
CREATE DATABASE hue DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
GRANT ALL ON hue.* TO 'hue'@'%' IDENTIFIED BY 'Hue123!';
flush privileges;修后修改hue的配置文件，找到[database]，修改如下属性
把mysql的driver包，放到安装目录的desktop/libs下面
bash
[hue@hdp3 libs]$ ll |grep mysql
-rw-r--r-- 1 hue hue 872303 10月 29 22:13 mysql-connector-java-5.1.27-bin.jar随后在安装目录下，执行初始化命令
bash
./build/env/bin/hue syncdb然后回出现下面的输出，跟着提示走
bash
[hue@hdp3 hue3.9]$ ./build/env/bin/hue syncdb

现在，启动Hadoop和Hiveserver2，启动hadoop的时候，要单独运行sbin/httpfs.sh start命令启动hadoop的https服务，最后就可以重启hue，访问8888端口了
正常使用你初始化元数据库时，创建的管理用户登录就行，一切正常的话，你就可以运行hive语句了，并且右上角可以查看yarn上的任务日志
最后要说一点，就是我前面配置hdfs的时候说的这里有个问题，当你点击页面的时候不难发现，你只能看到yarn任务的列表，无法点击直接跳到日志详情去，而且从左侧预览hdfs文件也会报一个oozie的错误，这是因为hue本身访问hdfs文件依赖的是oozie这个软件，个人测试或者学习安装一般都是cdh版本的hue，而oozie无论是本身的运行逻辑，还是cdh影响这些都是很大的不可控因素，比如cdh它的hdfs默认用户以及相关权限底层控制的都很复杂，所以我们直接使用这个组件的话，不太现实，所以我个人建议，用hue写Hivesql就行，毕竟有提示，至于其他的操作，其实本身上hue就不太行，推荐大家用zeppelin，我自己的测试集群用的就是，并且就是因为zeppelin写代码相关的时候没有提示，所以才留着hue的，不然我早删了它了。
