基础环境配置

a.修改主机名配置hosts

systemctl stop firewalld
hostnamectl set-hostname  ambari-server   #更改个主机名
sed -i 's/SELINUX=enforcing/SELINUX=disable/g' /etc/selinux/config
setenforce 0
cat >>/etc/hosts<<EOF    #添加各个节点hosts解析
172.20.2.222    ambari-server
172.20.2.203      hadoop-1
172.20.2.204      hadoop-2
172.20.2.205      hadoop-3
EOF

配置ambaer-server免密登录其他节点

a. 配置免密登录

ssh-keygen -t rsa     #在ambari-server生成密钥对
for num in `seq 1 3`;do ssh-copy-id -i /root/.ssh/id_rsa.pub root@bigdata${num};done

b.在ambari-server安装数据库

# 安装mariadb
yum -y install mariadb-server mysql-connector-java
systemctl start mariadb
mysql -uroot password
# 修改密码
use mysql;
UPDATE user SET password=PASSWORD('123456') WHERE user='root';
FLUSH PRIVILEGES;
# 允许其他用户连接
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
FLUSH PRIVILEGES;

安装时间同步NTP工具

a. 使用yum命令安装

yum install -y ntp

b. 检查ntp服务是否在启动时自动启动

systemctl is-enabled ntpd

c. 将 NTP 服务设置为启动时自动启动，请在每台主机上运行以下命令：

systemctl enable ntpd

d.每台服务器启动ntp

systemctl start ntpd

安装httpd服务器

执行命令

yum install httpd -y && systemctl start httpd

ambari+hdp安装

a.创建上传目录

mkdir /opt/sotfware

b.上传到目录下查看并解压

[root@bigdata01 software]# ls
ambari-2.7.5.0-centos7.tar.gz HDP-3.1.5.0-centos7-rpm.tar.gz   HDP-UTILS-1.1.0.22-centos7.tar.gz
# 创建解压目录 
mkdir -P /var/www/html/ambari
mkdir -p  /var/www/html/hdp/{HDP,HDP-UTILS-1.1.0.22}
# 解压
tar -zvxf ambari-2.7.5.0-centos7.tar.gz -C /var/www/html/ambari
tar -zvxf HDP-3.1.5.0-centos7-rpm.tar.gz -C  /var/www/html/hdp/HDP
tar -zvxf HDP-UTILS-1.1.0.22-centos7.tar.gz -C /var/www/html/hdp/HDP-UTILS-1.1.0.22

c.配置ambari的yum源

cat >/etc/yum.repos.d/ambari.repo<<EOF
#VERSION_NUMBER=2.7.5.0-72
[Updates-ambari-2.7.5.0]
name=ambari-2.7.5.0 - Updates

enabled=1
priority=1
EOF

d.配置hdp的yum源

cat >/etc/yum.repos.d/hdp.repo<<EOF
#VERSION_NUMBER=3.1.5.0-152
[HDP-3.1.5.0]
name=HDP Version - HDP-3.1.5.0

gpgcheck=1
gpgkey=http://172.0.0.201/hdp/HDP/HDP/centos7/3.1.5.0-152
enabled=1
priority=1

[HDP-UTILS-1.1.0.22]
name=HDP-UTILS Version - HDP-UTILS-1.1.0.22
baseurl=http://172.0.0.201/hdp/HDP-UTILS-1.1.0.22/HDP-UTILS/centos7/1.1.0.22
gpgcheck=1
gpgkey=http://172.0.0.201/hdp/HDP-UTILS-1.1.0.22/HDP-UTILS/centos7/1.1.0.22
enabled=1
priority=1
EOF

e.yum初始化

yum clean all
yum makecache

f. 安装ambari

# 安装
yum -y install ambari-server

# 进入数据库创建ambari库和导入数据
mysql>create database ambari DEFAULT CHARSET utf8;
mysql>use ambari
mysql>source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql

g.配置ambari-server
