Ambari2.5+HDP2.6集群配置安装

有道有笔记地址: http://note.youdao.com/noteshare?id=4a8bb0f1a02e3b9605824bc6ce3a1c9e
一、官方链接
  1. Ambari
版本:ambari-2.5.0.3-centos7
http://ambari.apache.org/
  1. HDP
版本:HDP-2.6.0.3-centos7-rpm HDP-UTILS-1.1.0.21-centos7.tar
https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.0.3/bk_ambari-installation/content/hdp_26_repositories.html
  1. CentOS
版本:CentOS-7-x86_64
https://www.centos.org/
在物理机下载好Ambari、HDP和HDP-UTILS的安装包,文件比较大在虚拟机下载速度太慢。注意下载的版本,和系统

二、配置系统环境
  1. 配置ip
1、设置虚拟机的网络连接方式为NAT
2、打开虚拟机网络编辑器:编辑——虚拟机网络编辑器——NAT设置
记录网关IP、子网掩码的信息
3、配置虚拟机网卡信息
#vi /etc/sysconfig/network-scripts/ifcfg-ens33
BOOTPROTO=static(此处设置为静态,默认为dhcp)
ONBOOT=yes(此处设置为yes,开机就自动执行)
IPADDR=192.168.42.201(设置IP地址,需要和子网在同一IP段)
GATEWAY=192.168.42.2(网关,网关地址在VM的网络连接设置里面)
NETMASK=255.255.255.0(子网掩码,子网掩码也在VM网络连接设置里面)
4、 重启网络设置
# systemctl restart network.service
5、查看网络连接情况,就看到ip地址更改为你设置的ip
# ifconfig
7 测试外网连接情况
#ping www.baidu.com
如果成功,则配置没问题。

  1. 配置hosts
#vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.42.201 hdp1.hadoop
192.168.42.202 hdp2.hadoop
更改为以上信息,注意必须要写成aaaa.aaaa的格式,需要配置几个节点就设置几个。

  1. 配置hostname
#vi /etc/hosts
设置为2步骤中对应节点的名字

  1. 安装基础软件包
#yum install openssh wget vim openssh-clients openssl gcc openssh-server mysql-connector-odbc -y
#systemctl enable sshd && systemctl start sshd

  1. 配置FQDN
# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=hdp1.hadoop

  1. 关闭防火墙和SELinux
#systemctl disable firewalld.service
#systemctl stop firewalld.service
#vi /etc/sysconfig/selinux
找到以下参数设置为关闭
SELINUX=disabled

  1. 修改为Yum源为阿里云
1、 echo 备份当前的yum源
#mv /etc/yum.repos.d /etc/yum.repos.d.backup4comex
2、echo 新建空的yum源设置目录
#mkdir /etc/yum.repos.d
3、echo 下载阿里云的yum源配置(根据系统版本,修改CentOS-后面的数值)
#wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
4、重建缓存
#yum clean all
#yum makecache

  1. 配置JDK
Oarcle官方链接: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
1、下载jdk
# mkdir ~/hadoop/java
#cd ~/hadoop/java
#wget http://download.oracle.com/otn-pub/java/jdk/8u151-b12/e758a0de34e24606bca991d704f6dcbf/jdk-8u151-linux-x64.tar.gz?AuthParam=1514519833_6514c37c7d6bc350d11cb6e334ccbde5
2、解压jdk到/opt/java
# mkdir -p /opt/java/ && tar xf jdk-8u151-linux-x64.tar.gz -C /opt/java
3、配置环境变量
# vim /etc/profile
添加下面内容:
export JAVA_HOME=/opt/java/jdk1.8.0_151
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
4、启用环境变量
# source /etc/profile
5、测试是否配置成功
#java -version
显示结果:
java version "1.8.0_151"
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)
以下两项有结果显示说明tools配置成功
#javac
#java

  1. 安装NTP
开启ntpd服务(确保集群内部时钟统一)
#yum -y install ntp
# systemctl is-enabled ntpd
# systemctl enable ntpd
# systemctl start ntpd

  1. 克隆虚拟机
1、关机
# shutdown -h now
2、克隆
点击VMware菜单栏的虚拟机——管理——克隆
出来对话框,点击两次下一步,在克隆类型选择创建完整克隆,虚拟机名称填写HDP2,点击完 成;需要几台虚拟机就克隆几台

  1. 配置克隆后的虚拟机ip、hosts、hostname
1、将克隆后的虚拟机依次开机
2、配置虚拟机网卡信息
#vi /etc/sysconfig/network-scripts/ifcfg-ens33
IPADDR=192.168.42.202(按照hosts中的映射,依次往后写)
3、 重启网络设置
# systemctl restart network.service
4、 测试外网连接情况
#ping www.baidu.com
如果成功,则配置没问题。
5、修改hostname
#vi /etc/hosts
修改为hosts中ip对应的值

  1. 配置ssh免密登陆
1、配置各个节点的私钥,并分发到主节点,各个节点都执行以下命令
#ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
#cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
#chmod 0600 ~/.ssh/authorized_keys
#cp ~/.ssh/id_rsa.pub ~/.ssh/id_rsa_hdp1(此处为各个节点名字).pub
#scp ~/.ssh/id_rsa_hdp1(此处为各个节点名字).pub [email protected]:~
传输的过程需要输入密码
2、把主节点的密钥分发到各个节点,在主节点执行以下代码
#for i in `seq (此处填写节点数) `;do cat ~/id_rsa_hdp$i.pub >>~/.ssh/authorized_keys ;done
#for i in `seq (此处填写节点数)`;do scp ~/.ssh/authorized_keys root@hdp$i.hadoop:~/.ssh/authorized_keys;done
3、测试
在各个节点测试以下能不能免密登陆,如果没问题则成功。
三、制作本地源
  1. 把下载好的Ambari、HDP、HDP-UTILs安装包传输到虚拟机
在物理机安装xfile软件,通过xfile连接虚拟机,把下载的文件传输到虚拟机的/root/hadoop/路径下。

  1. 安装httpd服务
# yum install httpd -y
#systemctl enable httpd && systemctl start httpd

  1. 解压源文件到到源目录下
#mkdir /var/www/html/ambari-HDP
#mkdir /var/www/html/ambari-HDP/HDP-UTILS
#mkdir /var/www/html/ambari-HDP/ambari
#mkdir /var/www/html/ambari-HDP/HDP
#tar xf /root/hadoop/ambari-2.5.0.3-centos7.tar.gz -C /var/www/html/ambari-HDP/ambari
# tar xf /root/hadoop/HDP-2.6.0.3-centos7-rpm.tar.gz -C /var/www/html/ambari-HDP/HDP
# tar xf /root/hadoop/HDP-UTILS-1.1.0.21-centos7.tar.gz -C /var/www/html/ambari-HDP/HDP-UTILS

  1. 安装links测试是否可用
#yum install links -y
# links http://hdp1.hadoop/ambari
结果显示的为刚刚解压的路径

  1. 复制ambari、HDP、HDP-UTILS的repo到yum
#cp /var/www/html/ambari-HDP/ambari/ambari/centos7/ambari.repo /etc.yum.repos.d
#cp /var/www/html/ambari-HDP/HDP/HDP/centos7/hdp.repo /etc.yum.repos.d
#cp /var/www/html/ambari-HDP/HDP-UTILS/hdp-utils.repo /etc.yum.repos.d

  1. 配置ambari、HDP、HDP-UTILS的repo
1、ambari
#vi /etc.yum.repos.d/ambari.repo
修改为如下配置
#VERSION_NUMBER=2.5.0.3-7
[ambari-2.5.0.3]
name=ambari Version - ambari-2.5.0.3
baseurl=http://hdp1.hadoop/ambari-HDP/ambari/ambari/centos7/
gpgcheck=1
gpgkey=http://hdp1.hadoop/ambari-HDP/ambari/ambari/centos7/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1
2、HDP
#vi /etc.yum.repos.d/hdp.repo
修改为如下配置:
#VERSION_NUMBER=2.6.0.3-8
[HDP-2.6.0.3]
name=HDP Version - HDP-2.6.0.3
baseurl=http://hdp1.hadoop/ambari-HDP/HDP/HDP/centos7/
gpgcheck=1
gpgkey=http://hdp1.hadoop/ambari-HDP/HDP/HDP/centos7/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1
[HDP-UTILS-1.1.0.21]
name=HDP-UTILS Version - HDP-UTILS-1.1.0.21
baseurl=http://hdp1.hadoop/ambari-HDP/HDP-UTILS
gpgcheck=1
gpgkey=http://hdp1.hadoop/ambari-HDP/HDP/HDP/centos7/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1
3、HDP-UTILS
#vi /etc.yum.repos.d/hdp-utils.repo
修改为如下配置:
[HDP-UTILS-1.1.0.21]
name=Hortonworks Data Platform Version - HDP-UTILS-1.1.0.21
baseurl= http://hdp1.hadoop/ambari-HDP/HDP-UTILS
gpgcheck=1
enabled=1
priority=1

  1. 安装本地源制作工具
#yum install yum-utils createrepo -y
#cd /var/www/html/
#createrepo ./

  1. 更新yum缓存
# yum clean all
# yum makecache
# yum repolist

四、安装Ambari-server
  1. 安装搭建mysql数据库
1.下载mysql的repo源
# wget https://repo.mysql.com//mysql57-community-release-el7-11.noarch.rpm
2安装mysql-community-release-el7-5.noarch.rpm包
#sudo rpm -ivh mysql-community-release-el7-11.noarch.rpm
安装这个包后,会获得两个mysql的yum repo源:
/etc/yum.repos.d/mysql-community.repo
/etc/yum.repos.d/mysql-community-source.repo
3.安装mysql
# sudo yum install mysql-server
根据提示安装就可以了,不过安装完成后没有密码,需要重置密码
如果此时提示关于 mariadb的错误,则是因为系统中装了mariadb我们需要卸载掉mariadb
查看系统是否安装mariadb
# rpm -qa | grep mariadb
如果显示有安装的信息,则卸载
# rpm -ev 此处填写上一步里面的列表 --nodeps
完成后再次执行 # yum install mysql-server
4.重置mysql密码
# mysql -u root
登录时有可能报这样的错:ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (2),原因是/var/lib/mysql的访问权限问题。下面的命令把/var/lib/mysql的拥有者改为当前用户:
# sudo chown -R root:root /var/lib/mysql
重启mysql服务
# service mysqld restart
接下来登录重置密码:
# mysql -u root //直接回车进入mysql控制台
mysql > use mysql;
mysql > update user set password=password('你的密码') where user='你的用户名,一般是root';
mysql > exit;

  1. 写入Ambari的信息到MySQL
#mysql -u root -p
输入密码,进入mysql的编辑命令
输入以下sql语句:
CREATE DATABASE ambari;
use ambari;
CREATE USER 'ambari'@'%' IDENTIFIED BY 'bigdata';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';
CREATE USER 'ambari'@'localhost' IDENTIFIED BY 'bigdata';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'localhost';
CREATE USER 'ambari'@'hdp1.hadoop' IDENTIFIED BY 'bigdata';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'hdp1.hadoop';
FLUSH PRIVILEGES;
source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql
show tables;
use mysql;
select Host,User,Password from user where user='ambari';
CREATE DATABASE hive;
use hive;
CREATE USER 'hive'@'%' IDENTIFIED BY 'hive';
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%';
CREATE USER 'hive'@'localhost' IDENTIFIED BY 'hive';
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'localhost';
CREATE USER 'hive'@'hdp1.hadoop' IDENTIFIED BY 'hive';
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'hdp1.hadoop';
FLUSH PRIVILEGES;
CREATE DATABASE oozie;
use oozie;
CREATE USER 'oozie'@'%' IDENTIFIED BY 'oozie';
GRANT ALL PRIVILEGES ON *.* TO 'oozie'@'%';
CREATE USER 'oozie'@'localhost' IDENTIFIED BY 'oozie';
GRANT ALL PRIVILEGES ON *.* TO 'oozie'@'localhost';
CREATE USER 'oozie'@'hdp1.hadoop' IDENTIFIED BY 'oozie';
GRANT ALL PRIVILEGES ON *.* TO 'oozie'@'hdp1.hadoop';
FLUSH PRIVILEGES;

  1. 安装ambari-server
1、开始安装
#yum install ambari-server
2、配置驱动
#mkdir /usr/share/java
通过xfile将物理机上的mysql-connector-java.jar复制到/usr/share/java目录下
将mysql-connector-java.jar复制到/var/lib/ambari-server/resources目录下
#cp /usr/share/java/mysql-connector-java.jar /var/lib/ambari-server/resources/mysql-jdbc- driver.jar
编辑ambari.properties
#vi /etc/ambari-server/conf/ambari.properties
修改server.jdbc.driver.path=/usr/share/java/mysql-connector-java.jar

  1. 配置Ambari-server
