二、配置服务器

1、安装必要依赖：

yum -y install net-tools vim ntp bzip2 gcc readline-devel zlib-devel httpd wget

2、所有服务器分别配置/etc/hosts文件：向其中添加以下3行

192.168.0.105 chavin.king chavin

192.168.0.107 chavin02.king chavin02

192.168.0.108 chavin03.king chavin03

192.168.0.109 chavin01.king chavin01

3、所有服务器均创建安装用户： ambari

groupadd ambari

useradd -g ambari ambari

echo "ambari" | passwd --stdin ambari

4、所有服务器为cloudera用户配置sudo权限

chmod u+w /etc/sudoers

echo "ambari ALL=(root)NOPASSWD:ALL" >> /etc/sudoers

chmod u-w /etc/sudoers

5、所有服务器关闭防火墙、禁用selinux

sed -i '/SELINUX=enforcing/d' /etc/selinux/config

sed -i '/SELINUX=disabled/d' /etc/selinux/config

echo "SELINUX=disabled" >> /etc/selinux/config

systemctl stop firewalld

systemctl disable firewalld

6、所有服务器设置文件打开数量及最大进程数

cp /etc/security/limits.conf /etc/security/limits.conf.bak

echo "* soft nproc 32000" >>/etc/security/limits.conf

echo "* hard nproc 32000" >>/etc/security/limits.conf

echo "* soft nofile 65535" >>/etc/security/limits.conf

echo "* hard nofile 65535" >>/etc/security/limits.conf

7、配置SSH无秘钥登录：至少在namenode和resourcemanager节点配置

ssh-keygen -t rsa

ssh-copy-id chavin.king

ssh-copy-id chavin01.king

ssh-copy-id chavin02.king

ssh-copy-id chavin03.king

8、配置集群时间同步服务：通过ntp服务配置

ntp主节点配置：

cp /etc/ntp.conf /etc/ntp.conf.bak

cp /etc/sysconfig/ntpd /etc/sysconfig/ntpd.bak

echo "restrict 192.168.0.0 mask 255.255.255.0 nomodify notrap" >> /etc/ntp.conf

echo "SYNC_HWCLOCK=yes" >> /etc/sysconfig/ntpd

systemctl restart ntpd

ntp客户端配置：

#crontab -e

输入如下一行内容，保存退出：

0-59/1 * * * * /opt/scripts/sync_time.sh

上述脚本内容如下：

# cat /opt/scripts/sync_time.sh

/sbin/service ntpd stop

/usr/sbin/ntpdate chavin

/sbin/service ntpd start

9、所有节点安装java软件并配置环境变量

export JAVA_HOME=/usr/java/jdk1.8.0_181

export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$CLASSPATH

10、安装postgresql数据库

参考文档：https://www.cnblogs.com/wcwen1990/p/6655438.html

官网下载：postgresql-9.5.5.tar.bz2

安装：

tar -jxvf postgresql-9.5.5.tar.bz2

cd postgresql-9.5.5

./configure --prefix=/pg955

make world

make install-world

userdel postgres

groupadd postgres

useradd -g postgres postgres

chown -R postgres:postgres /pg955/

su - postgres

配置环境变量：

vim .bash_profile

export PGHOME=/pg955

export PGDATA=/pg955/data

export LD_LIBRARY_PATH=$PGHOME/lib:$LD_LIBRARY_PATH

PATH=$PGHOME/bin:$PATH

初始化数据库：

pg_ctl init

修改配置文件：

vim postgresql.conf

listen_addresses = '*'

修改访问控制文件：

vim pg_hba.conf

host all all 192.168.0.0/24 md5

启动数据库：

pg_ctl start -l $PGHOME/logfile 2>&1 >/dev/null

修改postgres数据库密码：

psql

postgres=# \password

创建ambari数据库：

create user ambari with password 'ambari';

create database ambari owner=ambari encoding 'utf8' template template0;

grant all privileges on database ambari to ambari;

create schema ambari;

11、安装apache服务器：

service httpd start

cd /var/www/htmp

mkdir ambari

mkdir hdp

三、安装ambari

1、上传文件并解压相应文件：

上传ambari和hdp安装文件到主服务器上，解压ambari文件到/var/www/htmp/ambari/目录下，解压hdp和hdp-untils文件到/var/www/htmp/hdp/目录下。

tar -zxvf ambari-2.7.0.0-centos7.tar.gz -C /var/www/html/ambari/

tar -zxvf HDP-3.0.0.0-centos7-rpm.tar.gz -C /var/www/html/hdp/

tar -zxvf HDP-UTILS-1.1.0.22-centos7.tar.gz -C /var/www/html/hdp/

2、配置yum源文件

wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.7.0.0/ambari.repo .

vim ambari.repo

#VERSION_NUMBER=2.7.0.0-897

5、执行数据库脚本

psql --host=chavin.king --port=5432 --username=ambari -f /var/lib/ambari-server/resources/Ambari-DDL-Postgres-CREATE.sql

6、启动ambari-server

[root@chavin ~]# ambari-server start

2、输入集群名称chavin_cluster，然后点击next：

3、配置本地yum源：

4、指定集群机器，输入id_rsa密钥：

5、等待

等待

这里使用了ntp进行时间同步，忽略。

6、下一步：

7、根据规划配置

8、根据规划配置

9、为各个账号设置密码

10、配置数据，首先要配置postgresql驱动：ambari-server setup --jdbc-db=postgres --jdbc-driver=/mnt/postgresql-42.2.5.jar，然后根据数据库连接地址配置，也可以选择mysql数据库

11、根据规划配置：

12、根据规划配置：

13、规矩规划配置：

14、安装概要

15、等待安装完成，时间较长：

16、安装完成，因资源不足，某些组建出现警告，忽略。

17、至此，HDP安装完成。
