Linux-centos7安装大数据管理组件Ambari-server

1. Ambari 简介

Apache Ambari是一种基于Web的工具，支持Apache Hadoop集群的供应、管理和监控。Ambari已支持大多数Hadoop组件，包括HDFS、MapReduce、Hive、Pig、 Hbase、Zookeeper、Sqoop和Hcatalog等。

2. 安装环境准备

1. ssh 免密码登录

修改主机名
vi /etc/sysconfig/network
Created by anaconda
HOSTNAME=master.ambari

三台机器master，work1，work2之间可以免密码登录

2. JDK

3.python2.7+（三台机器同样的操作）

Ambari用python2.*写的，Python3会报错
一般centos7会自带python2.7，/usr/bin/python2.7

用which is python 查看当前的python环境是/opt/anaconda3/bin/下的python
cd /opt/anaconda3/bin
ll |grep python

删除python链接
[root@master bin]# rm -rf python

然后新建Python2.*的链接

(base) [root@master bin]# whereis python
python: /usr/bin/python /usr/bin/python2.7 /usr/bin/python2.7-config /usr/lib/python2.7 /usr/lib/python2.6 /usr/lib64/python2.7 /etc/python /usr/include/python2.7 /opt/anaconda3/bin/python3.6 /opt/anaconda3/bin/python3.6-config /opt/anaconda3/bin/python3.6m-config /opt/anaconda3/bin/python3.6m /usr/share/man/man1/python.1.gz
(base) [root@master bin]# pwd
/opt/anaconda3/bin
(base) [root@master bin]# ln -s /usr/bin/python2.7 /opt/anaconda3/bin/python
(base) [root@master bin]# ll |grep python
