基于Centos7.6上Ambari2.7.4+HDP3.1.4离线安装

概述

Ambari:基于Web的工具,支持Apache Hadoop集群的创建 、管理和监控。可以从apache官网下载源码,自己定义开发自己需要的样式。这里先设下一个伏笔,有兴趣的可以跟着我的博客。后面会有apache-ambari二次开发。
HDP:包含了hadoop生态系统的所有软件项目,比如HBase,Zookeeper,Hive,Pig等等。
HDP-UTILS:工具类库。
HDP-GPL:LZO压缩库软件包存储在单独的HDP-GPL存储库中。

  Ambari的最新版本为2.7.5,HDP的最新版本为3.1.5,通过 https://supportmatrix.hortonworks.com/ 可以查询Ambari和HDP各个版本支持情况。本来想安装最新版,但因为从2.7.5之后,访问Ambari存储库需要身份验证。具体官网截图如下,(浏览器以翻译为中文):  

基于Centos7.6上Ambari2.7.4+HDP3.1.4离线安装

 废话不多说,开始搞起。

环境

系统:CentOS Linux release 7.6.1810 (Core)
内存:16G
cpu:1C
磁盘:100G
安装介质:[ ambari-2.7.4.0-centos7.tar.gz | HDP-3.1.4.0-centos7-rpm.tar.gz | HDP-GPL-3.1.4.0-centos7-gpl.tar.gz | HDP-UTILS-1.1.0.22-centos7.tar.gz ]

设置主机名:

方法:之前博客 《TDH(Transwarp Data Hub)社区版安装教程》中 设置主机名

设置root用户登录:

方法:之前博客 《TDH(Transwarp Data Hub)社区版安装教程》中 设置root用户登录

设置集群免密:

方法:之前博客 《TDH(Transwarp Data Hub)社区版安装教程》中 设置集群免密

设置selinux,集群时间同步,防火墙:

方法:之前博客 《TDH(Transwarp Data Hub)社区版安装教程》中 设置selinux,集群时间同步,防火墙

补充:时间同步,这里配置的集群间,所有节点以主节点时间为准,都同步主节点时间

步骤:

注意事项:要注意的是,ntpd 有一个自我保护设置: 如果本机与上源时间相差太大, ntpd 不运行. 所以新设置的时间服务器一定要先 ntpdate 从上源取得时间初值, 然后启动 ntpd服务。ntpd服务 运行后, 先是每64秒与上源服务器同步一次, 根据每次同步时测得的误差值经复杂计算逐步调整自己的时间, 随着误差减小, 逐步增加同步的间隔.每次跳动, 都会重复这个调整的过程。

主节点配置

修改两处:

restrict 10.32.8.0 mask 255.255.255.0 nomodify notrap

server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10

修改后具体参数:

基于Centos7.6上Ambari2.7.4+HDP3.1.4离线安装
[root@nn1 ~]# cat /etc/ntp.conf | grep -v ^# | grep -v ^$
driftfile /var/lib/ntp/drift
restrict default nomodify notrap nopeer noquery
restrict 127.0.0.1 
restrict ::1
restrict 10.32.8.0 mask 255.255.255.0 nomodify notrap
server  127.127.1.0     # local clock
fudge   127.127.1.0 stratum 10
includefile /etc/ntp/crypto/pw
keys /etc/ntp/keys
disable monitor
View Code

修改配置后需要重启ntpd服务:systemctl restart ntpd 

从节点配置

根据上面的注意事项,先同步主节点时间:ntpdate nn1

从节点修改一处:server nn1

修改后具体参数:

基于Centos7.6上Ambari2.7.4+HDP3.1.4离线安装
[root@dn1 ~]# cat /etc/ntp.conf | grep -v ^# | grep -v ^$
driftfile /var/lib/ntp/drift
restrict default nomodify notrap nopeer noquery
restrict 127.0.0.1 
restrict ::1
server nn1
includefile /etc/ntp/crypto/pw
keys /etc/ntp/keys
disable monitor
View Code

启动ntpd服务:systemctl start ntpd

除了上面的方法外还有一种,就是在从节点添加定时任务,同步主节点时间。

安装jdk

所有节点安装jdk:

基于Centos7.6上Ambari2.7.4+HDP3.1.4离线安装
[root@nn1 ~]# tar zxvf jdk-8u251-linux-x64.tar.gz -C /usr/local/

[root@nn1 ~]# mv /usr/local/jdk1.8.0_251/ /usr/local/jdk

环境变量:在/etc/profile 中添加
# for jdk
export JAVA_HOME=/usr/local/jdk
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

刷新环境变量:source /etc/profile

检查:
[root@nn1 ~]# java -version
java version "1.8.0_251"
Java(TM) SE Runtime Environment (build 1.8.0_251-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.251-b08, mixed mode)
View Code

关闭THP

所有节点在文件/etc/rc.d/rc.local中添加以下内容:

基于Centos7.6上Ambari2.7.4+HDP3.1.4离线安装
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
    echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
    echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi
View Code [root@dn1 opt]# chmod +x /etc/rc.d/rc.local

修改文件打开最大限制

修改文件/etc/security/limits.conf,添加已下内容:

* soft nofile 65536 
* hard nofile 65536 
* soft nproc 131072

在配置前需要先配置一下postgresql,如下:

基于Centos7.6上Ambari2.7.4+HDP3.1.4离线安装
在主节点的postgresql上创建hive数据库,hive用户,并将hive数据库授权给hive用户。
[root@nn1 ~]# su - postgres
Last login: Tue Jun 30 17:14:36 UTC 2020 on pts/2
-bash-4.2$ psql 
psql (9.2.24)
Type "help" for help.

postgres=# CREATE DATABASE hive;
CREATE DATABASE
postgres=# CREATE USER hive WITH PASSWORD 'hive';
CREATE ROLE
postgres=# GRANT ALL PRIVILEGES ON DATABASE hive TO hive;
GRANT
postgres=# \q

修改/var/lib/pgsql/data/pg_hba.conf文件
将
local  all  ambari,mapred md5
host  all   ambari,mapred 0.0.0.0/0  md5
host  all   ambari,mapred ::/0 md5

改为
local  all  ambari,mapred,hive md5
host  all   ambari,mapred,hive 0.0.0.0/0  md5
host  all   ambari,mapred.hive ::/0 md5

修改后,重新启动postgresql: systemctl restart postgresql.service
