部署前的准备

配置数据库

• 建立ambari数据库
  这里是因为ambari需要一个数据库存放元数据与用户信息。

mysql> create database ambari default character set utf8;
mysql> create user 'ambari'@'%' identified by 'bigdata';
mysql> grant all privileges on ambari. * to 'ambari'@'%';
mysql> flush privileges;

• 导入JDBCjar包
  上传 mysql-connector-java-5.1.XX.jar。

chmod 777 mysql-connector-java-5.1.XX.jar
ln -s mysql-connector-java-5.1.XX.jar mysql-connector-java.jar

配置ambari-yum源

先创建一个目录存放需要用到的文件。

[root@ambari hdk] cd /var/www/html/
[root@ambari html] mkdir hdp_repo

第一个文件：ambari-2.7软件包
https://docs.cloudera.com/HDPDocuments/Ambari-2.7.1.0/bk_ambari-installation/content/ambari_repositories.html

软件包

第二，三，四个文件：HDP,HDP-UTILS,HDP-GPL
https://docs.cloudera.com/HDPDocuments/Ambari-2.7.1.0/bk_ambari-installation/content/hdp_30_repositories.html

其他软件包

然后把四个工具包全部上传上来，解压。

工具包

然后删掉工具包，访问：http://192.168.10.190/hdp_repo。

镜像站

然后去yum源存放的目录，为他们添加本地源。

cd /etc/yum.repo.d/

vi ambari.repo
cat ambari.repo
[ambari-2.7.1.0]
name=ambari_repo
baseurl=http://192.168.10.190/hdp_repo/ambari/centos7/2.7.1.0-169
gpgcheck=0
enabled=1

vi hdp.repo
cat hdp.repo
[HDP-3.0.1.0]
name=hdp_repo
baseurl= http://192.168.10.190/hdp_repo/HDP/centos7/3.0.1.0-187
gpgcheck=0
enabled=1

vi hdp-utils.repo
cat hdp-utils.repo
[HDP-UTILS-1.1.0.22]
name=hdp_utils_repo
baseurl= http://192.168.10.190/hdp_repo/HDP-UTILS/centos7/1.1.0.22
gpgcheck=0
enabled=1

vi hdp-gpl.repo
cat hdp-gpl.repo
[HDP-GPL-3.0.1.0-187]
name=hdp_gpl_repo
baseurl= http://192.168.10.190/hdp_repo/HDP-GPL/centos7/3.0.1.0-187
gpgcheck=0
enabled=1

部署ambari

安装

yum install ambari-server

安装完成

连接数据库

首先把mysql的jar包传上来。

cd /usr/share
mkdir java
#上传
chmod 777 mysql-connector-java-5.1.46.jar 
mv mysql-connector-java-5.1.46.jar mysql-connector-java.jar

jdbc-jar

然后把jar包导入进去。

ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar
