标签 ambari2.6.0 ambari 安装 hdp2.6.3 hdp 离线繁體版

原文原文链接

1、下载安装包

　　由于使用在线安装特别慢，全部的安装包加起来有9个G左右，因此本教程是经过迅雷下载包，而后上传到服务器，经过配置本地源的方式来实现的离线安装。经过ambari安装须要下载下面的三个主要包：html

HDP：http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.6.3.0/HDP-2.6.3.0-centos7-rpm.tar.gzjava

ambari：http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.6.0.0/ambari-2.6.0.0-centos7.tar.gznode

HDP-UTILS：http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.21/repos/centos7/HDP-UTILS-1.1.0.21-centos7.tar.gzpython

注意问题：安装的centos系统必选选择英文版本，否则里面有些地方为莫名出错mysql

2、系统环境配置

一、安装jdk（全部机器）

通常linux自带的jdk或者是经过yum安装的jdk都是openjdk,可是最好是使用oracle/sun jdk,前者是开源的，缺失部分功能，后者是官方的。可是若是直接安装oracle的jdk，第三方的依赖包不会安装，因此最有效的额方式是经过yum安装openjdk，并同时安装了第三方依赖包，而后卸载openjdk，经过本身来安装oracle的jdk，就能解决依赖问题。 linux

（1）安装openjdk

[root@master ~]# yum -y install java
[root@master ~]# java -version
openjdk version "1.8.0_161"
OpenJDK Runtime Environment (build 1.8.0_161-b14)
OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)
[root@master ~]# rpm -qa|grep java
javapackages-tools-3.4.1-11.el7.noarch
java-1.8.0-openjdk-1.8.0.161-0.b14.el7_4.x86_64
python-javapackages-3.4.1-11.el7.noarch
tzdata-java-2018d-1.el7.noarch
java-1.8.0-openjdk-headless-1.8.0.161-0.b14.el7_4.x86_64

（2）下载oracle

下载地址：http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.htmlsql

选择下载上面标红的jdk的版本1.8.0_161 jdk-8u161-linux-x64.rpm，而后上传到服务器数据库

（3）卸载OpenJDK

[root@master ~]# rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.161-0.b14.el7_4.x86_64
[root@master ~]# rpm -e --nodeps java-1.8.0-openjdk-1.8.0.161-0.b14.el7_4.x86_64

（4）安装下载好的jdk

[root@master ~]# rpm -ivh jdk-8u161-linux-x64.rpm 
准备中...                          ################################# [100%]

Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)
[root@master ~]# javac -version
javac 1.8.0_161

二、修改本机名（全部机器）

　　经过vi /etc/hostname 进行修改centos

　　各个节点修改为相应的名称，分别为master,slave1.slave2.slave3,例浏览器

master

　　而后重启电脑

三、修改/etc/hosts文件（全部机器）

　　这里主要是为了能够实现经过名称来查找相应的服务器

[root@master ~]# vi /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.12.101 master
192.168.12.102 slave1
192.168.12.103 slave2
192.168.12.104 slave3

　四、修改/etc/sysconfig/network（全部机器）

[root@master ~]# vi /etc/sysconfig/network
# Created by anaconda
NETWORKING=yes

　　接下来就能够经过测试一下是否能够经过ping主机名来找到对应的服务器

[root@master ~]# ping slave1
PING slave1 (192.168.12.102) 56(84) bytes of data.
64 bytes from slave1 (192.168.12.102): icmp_seq=1 ttl=63 time=0.134 ms
64 bytes from slave1 (192.168.12.102): icmp_seq=2 ttl=63 time=0.132 ms
64 bytes from slave1 (192.168.12.102): icmp_seq=3 ttl=63 time=0.133 ms
64 bytes from slave1 (192.168.12.102): icmp_seq=4 ttl=63 time=0.133 ms
64 bytes from slave1 (192.168.12.102): icmp_seq=5 ttl=63 time=0.132 ms
^C
--- slave1 ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4000ms
rtt min/avg/max/mdev = 0.132/0.132/0.134/0.014 ms

五、修改文件打开限制（全部机器）

[root@master ~]# vi /etc/security/limits.conf
# End of file
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072

六、关闭防火墙（全部机器）

[root@master~]#systemctl disable firewalld
[root@master~]#systemctl stop firewalld

　　除此以外

[root@master ~]# cat /etc/selinux/config 
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

七、同步时钟

（1）安装ntp服务（全部机器）

[root@master ~]#yum -y install ntp

（2）设置master为主服务器，开启nptd服务(主服务器)

[root@master ~]#vi /etc/ntp.conf

如图：

[root@master ~]# systemctl start ntpd.service       #启动服务
[root@master ~]# systemctl enable ntpd.service      #开机自启动

(3)、子节点设置同步（子节点）

　　主服务器开启ntp服务器之后，子节点就不须要开启了，由于当server与client之间的时间偏差过大时（多是1000秒），处于对修改时间可能对系统和应用带来不可预知的问题，NTP将中止时间同步！因此若是发现NTP启动以后时间并不进行同步时，应该考虑到多是时间差过大引发的，此时须要先手动进行时间同步！因此直接使用定时手动同步的方式就能够了。

[root@slave1 data]# crontab -e
0-59/10 * * * * /usr/sbin/ntpdate master
crontab: installing new crontab
[root@slave1 data]# crontab -l
0-59/10 * * * * /usr/sbin/ntpdate master

八、SSH无密码登录（主节点）

配置master节点无密码登陆到其余节点，在master节点上操做

[root@master ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:NMVPXezqq+MPf95MtP5bzaghnvXSljcC4BH/QFCvm+I root@master
The key's randomart image is:
+---[RSA 2048]----+

测试是否实现了无密码登陆

[root@master ~]# ssh slave1 date ;ssh slave2 date;ssh slave3 date;ssh master date;
2018年 04月 23日 星期一 14:18:13 CST
2018年 04月 23日 星期一 14:18:13 CST
2018年 04月 23日 星期一 14:18:13 CST
2018年 04月 23日 星期一 14:18:13 CST

将建立的秘钥拷贝出来，由于后面ambari安装的时候须要上传这个秘钥。建立秘钥是在隐藏文件夹/root/.ssh/下面的，因此须要先把秘钥拷贝到可见区域，而后拷贝到电脑上。下面标红的就是秘钥文件

[root@master ~]# cd /root/.ssh/
[root@master .ssh]# ls
authorized_keys  id_rsa  id_rsa.pub  known_hosts
[root@master .ssh]# cp id_rsa /root/
[root@master .ssh]# ls /root/
anaconda-ks.cfg   id_rsa  jdk-8u161-linux-x64.rpm

九、其余系统设置（全部机器）

[root@master ~]# sudo sh -c "echo umask 0022 >> /etc/profile"

3、修改yum源，实现离线安装

一、安装httpd服务（主服务器）

[root@master ~]# yum -y install httpd
[root@master ~]# service httpd restart
Redirecting to /bin/systemctl restart httpd.service
[root@master ~]# chkconfig httpd on

二、将上面下载的三个包放到/var/www/html目录下（主服务器）

[root@master ~]# cd /var/www/html/
[root@master html]# mkdir ambari
拷贝文件到ambari下面
[root@master html]# cd ambari/
[root@master ambari]# ls
ambari-2.6.0.0-centos7.tar.gz  HDP-2.6.3.0-centos7-rpm.tar.gz  HDP-UTILS-1.1.0.21-centos7.tar.gz
[root@master ambari]# tar -zxvf ambari-2.6.0.0-centos7.tar.gz
[root@master ambari]# tar -zxvf HDP-2.6.3.0-centos7-rpm.tar.gz 
[root@master ambari]# mkdir HDP-UTILS
[root@master ambari]# tar -zxvf HDP-UTILS-1.1.0.21-centos7.tar.gz -C HDP-UTILS
[root@master ambari]# rm -rf ambari-2.6.0.0-centos7.tar.gz HDP-2.6.3.0-centos7-rpm.tar.gz HDP-UTILS-1.1.0.21-centos7.tar.gz 
[root@master ambari]# ls
ambari  HDP  HDP-UTILS

如今能够经过访问http://192.168.12.101/ambari/查看是否能成功访问

三、制做本地源

（1）安装本地源制做相关工具（主服务器）

[root@master ambari]# yum install yum-utils createrepo yum-plugin-priorities -y
[root@master ambari]#  createrepo  ./

（2）修改文件里面的源地址（主服务器）

[root@master ambari]# vi ambari/centos7/2.6.0.0-267/ambari.repo
#VERSION_NUMBER=2.6.0.0-267
[ambari-2.6.0.0]
name=ambari Version - ambari-2.6.0.0
baseurl=http://192.168.12.101/ambari/ambari/centos7/2.6.0.0-267
gpgcheck=1
gpgkey=http://192.168.12.101/ambari/ambari/centos7/2.6.0.0-267/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1
[root@master ambari]# cp ambari/centos7/2.6.0.0-267/ambari.repo /etc/yum.repos.d/
[root@master ambari]# vi HDP/centos7/2.6.3.0-235/hdp.repo
#VERSION_NUMBER=2.6.3.0-235
[HDP-2.6.3.0]
name=HDP Version - HDP-2.6.3.0
baseurl=http://192.168.12.101/ambari/HDP/centos7/2.6.3.0-235
gpgcheck=1
gpgkey=http://192.168.12.101/ambari/HDP/centos7/2.6.3.0-235/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://192.168.12.101/ambari/HDP-UTILS
gpgcheck=1
gpgkey=http://192.168.12.101/ambari/HDP-UTILS/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1
[root@master ambari]# cp HDP/centos7/2.6.3.0-235/hdp.repo /etc/yum.repos.d/

上面就建立好了主机上的文件，而后能够经过下面命令清楚一下yum的缓存就能够了

[root@master ambari]# yum clean all
[root@master ambari]# yum makecache
[root@master ambari]# yum repolist

（3）将建立好的文件拷贝到子节点（主服务器）

[root@master ambari]#cd /etc/yum.repos.d
[root@master yum.repos.d]# scp ambari.repo slave1:/etc/yum.repos.d/
ambari.repo                                                                                        100%  274    16.3KB/s   00:00    
[root@master yum.repos.d]# scp ambari.repo slave2:/etc/yum.repos.d/
ambari.repo                                                                                        100%  274   115.7KB/s   00:00    
[root@master yum.repos.d]# scp ambari.repo slave3:/etc/yum.repos.d/
ambari.repo                                                                                        100%  274   608.9KB/s   00:00    
[root@master yum.repos.d]# scp hdp.repo slave1:/etc/yum.repos.d/
hdp.repo                                                                                           100%  482     1.1MB/s   00:00    
[root@master yum.repos.d]# scp hdp.repo slave2:/etc/yum.repos.d/
hdp.repo                                                                                           100%  482   969.5KB/s   00:00    
[root@master yum.repos.d]# scp hdp.repo slave3:/etc/yum.repos.d/
hdp.repo

4、安装ambari-server

通过不断的安装，有两种模式，一种是默认postgresql数据库的安装方式，这种不推荐生产环境使用，还有一种方式是使用第三方数据库的安装方式，下面介绍两种安装模式，根据我的需求选择。建议使用自带的postgresql来配置数据库，这样在后面安装过程当中不会出现问题，若是使用其它数据库，请参考其它教程来设置

一、默认安装方式，使用默认数据库PostgreSQL（不推荐生产环境使用）（主服务器）

（1）、安装和配置ambari-server

[root@master yum.repos.d]# yum -y install ambari-server
[root@master yum.repos.d]# ambari-server setup

（2）、启动ambari

[root@master ~]# ambari-server start

成功启动后在浏览器输入Ambari地址：

http://192.168.12.101:8080

二、以mysql为数据库安装（主服务器）

（1）安装mysql数据库

[root@master ~]# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
[root@master ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm
[root@master ~]# yum install mysql-community-serve

（2）启动mysql，设置开机启动

[root@master ~]# service mysqld start
[root@master ~]# vi /etc/rc.local
#添加service mysqld start

（3）登陆进mysql，初始化设置root密码

[root@master ~]# mysql -uroot 

设置登陆密码
mysql> set password for 'root'@'localhost' = password('yourPassword');

添加远程登陆用户
mysql> grant all privileges on *.* to 'root'@'%' identified by 'yourPassword';

远程登陆
#mysql -uroot -h ip(远程的ip地址) -p

[root@master yum.repos.d]# yum -y install ambari-server

（4）登陆mysql，执行下面的语句

CREATE DATABASE ambari;  
use ambari;  
CREATE USER 'ambari'@'%' IDENTIFIED BY 'ambarizk123';  
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';  
CREATE USER 'ambari'@'localhost' IDENTIFIED BY 'ambarizk123';  
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'localhost';  
CREATE USER 'ambari'@'master' IDENTIFIED BY 'ambarizk123';  
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'master';  
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'@'master' IDENTIFIED BY 'hive';  
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'master';  
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'@'master' IDENTIFIED BY 'oozie';  
GRANT ALL PRIVILEGES ON *.* TO 'oozie'@'master';  
FLUSH PRIVILEGES;

（5）简历mysql与ambari-server的链接

网上下载mysql-connector-java-5.1.40.jar放到root文件下

mkdir /usr/share/java
cp /root/mysql-connector-java-5.1.40.jar /usr/share/java/mysql-connector-java.jar
cp /usr/share/java/mysql-connector-java.jar /var/lib/ambari-server/resources/mysql-jdbc-driver.jar
vi /etc/ambari-server/conf/ambari.properties

Proceed with configuring remote database connection properties [y/n] (y)?

[root@master ~]# ambari-server start

三、错误处理

　　若是出现错误，请注意查看日志，根据具体的错误内容进行处理，默认ambari-server的日志在/var/log/ambari-server/ambari-server.log里面。若是在处理日志的过程当中或者后面安装的过程当中出现一些莫名的错误，能够重置的安装。若是上面进行的默认数据库的配置，可使用下面的代码重置ambari-server

[root@master ~]# ambari-server stop
[root@master ~]# ambari-server reset
[root@master ~]# ambari-server setup

　　若是选择的是第二种方式，就须要先执行上面的语句，而后手动将mysql里面建立的数据库进行删除。而后再从新执行第二步的操做

[root@master ~]# mysql -uroot -p
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| ambari             |
| hive               |
| oozie              |
| performance_schema |
+--------------------+
5 rows in set (0.00 sec)
mysql> drop database ambari;
mysql> drop database hive;
mysql> drop database oozie;

　　若是在安装的过程当中出现了错误，又想从新安装，能够在ambari-server开启的状况下，执行下面的语句来移除已安装的包，而后再经过不一样的状况选择上面两种方式的一种对ambari-server进行重置

python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py --silent

5、安装配置部署HDP集群

一、登陆

登陆界面，默认管理员帐户登陆，帐户：admin 密码：admin

二、安装向导

（1）配置集群的名字为hadoop

（2）选择版本并修改成本地源地址

（3）安装配置

选择要安装的服务器和上传上面教程所拷贝出来的秘钥文件id_rsa

（4）安装ambari的agent，同时检查系统问题

若是这里出了问题，请检查上面全部的步骤有没有遗漏和未设置的参数。同时在从新修改了配置之后，最好是重置ambari-server来从新进行安装

[root@master ~]# # ambari-server stop    
[root@master ~]# # ambari-server reset   #重置命令
[root@master ~]# # ambari-server setup   #从新设置
[root@master ~]# # ambari-server start

（5）选择要安装的服务

（6）选择分配服务

（7）选择

建议nodemanager、regionserver、client全都勾选上，第一个datanode根据主机的磁盘容量选择。

（8）根据提示修改一些错误，注意hive和oozie的数据库配置问题。若是最开始初始化ambari-server的时候使用的是默认配置，这里就最好使用new的方式，若是使用的是New MySQL Database ，这须要选择Existing MySQL / MariaDB Database ，而后测试一下是否能链接上
