ambari的安装

一、准备工作

1、机器信息

ip地址	机器名
172.18.1.22	bgsbtsp0006-dqf
172.18.1.23	bgsbtsp0007-dqf
172.18.1.24	bgsbtsp0008-dqf
172.18.1.25	bgsbtsp0009-dqf
172.18.1.26	bgsbtsp0010-dqf

2、创建ambari用户并初始化密码

[root@bgsbtsp0006-dqf ~]# for i in {22..26}; do ssh 172.18.1.$i "groupadd ambari && useradd -g ambari -d /home/ambari ambari"; done

[root@bgsbtsp0006-dqf ~]# for i in {22..26}; do ssh 172.18.1.$i "echo 'baifendian' | passwd --stdin ambari"; done

3、ambari用户之间打通key（root用户也需要免秘钥打通）

[root@bgsbtsp0006-dqf ~]# su - ambari
[ambari@bgsbtsp0006-dqf ~]$ ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/home/ambari/.ssh/id_rsa): Created directory '/home/ambari/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/ambari/.ssh/id_rsa.
Your public key has been saved in /home/ambari/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:sej6QxrYlRgpLZx+ib2ffIg3ttSe0hoCsSd04UDGVjo ambari@bgsbtsp0006-dqf
The key's randomart image is:
+---[RSA 2048]----+
| +++o.           |
| .B++.           |
| oE=o+ ..        |
| .o== o. o       |
|  ++.o. S        |
|  .++...         |
|    .B++.        |
|    o+@oo.       |
|    .++Bo        |
+----[SHA256]-----+

4、验证是否打通

[ambari@bgsbtsp0006-dqf ~]$ for i in {22..26};do ssh 172.18.1.$i "echo Ok";done
Ok
Ok
Ok
Ok
Ok

5、mysql的安装

mysql-5.5.39版本的安装
mysql-5.7.20版本的安装

6、后续要装hive组件，需要先在mysql中创建hived的源数据库

[ambari@bgsbtsp0006-dqf ~]$ mysql -uroot -p
Enter password: 
[ambari@bgsbtsp0006-dqf ~]$ mysql -uroot -p
Enter password: 
mysql> create database hive character set utf8;
Query OK, 1 row affected (0.00 sec)
mysql> create user hive identified by 'baifendian';
Query OK, 1 row affected (0.00 sec)
mysql> grant all privileges on hive.* to 'hive'@'localhost' identified BY 'baifendian';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> grant all privileges on hive.* to 'hive'@'172.18.1.22' identified BY 'baifendian';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> grant all privileges on hive.* to 'hive'@'bgsbtsp0006-dqf' identified BY 'baifendian';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> grant all privileges on hive.* to 'hive'@'%' identified BY 'baifendian';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

7、配置yum源

用的公司配好的yum源，可以自己配置，repo文件也需要放到agent端机器，（安装大数据组件需要）

[root@hadoop1 yum.repos.d]# cd /etc/yum.repos.d
 wget http://mirror.baifendian.com/yum/HDP/centos7/2.x/updates/2.6.1.0/hdp.repo
 wget http://mirror.baifendian.com/yum/HDP-UTILS-1.1.0.21/repos/centos7/hdp-util.repo
 wget http://mirror.baifendian.com/yum/ambari/centos7/ambari.repo
 wget http://mirror.baifendian.com/yum/centos/CentOS-Base.repo
 wget http://mirror.baifendian.com/yum/epel/epel.repo

8、时间同步

最简单的是手同步执行date -s 'xxx:xxx:xxx'
ntp时间同步服务器

9、检查防火墙

[root@hadoop1 opt]# service iptables status
[root@hadoop1 opt]# service iptables stop

10、检查java是否安装

jdk的tar包安装

二、开始安装ambari

1、ambari数据库创建（上面的内容是后来加的，所以和下面机器名称对不上，上面是为了部署大数据组件所做的准备，ambari的安装只需要在一台机器上即可。）

[ambari@hadoop1 opt]# mysql -uroot -p

mysql> create database ambari character set utf8;

mysql> create user ambari identified by '1234';

mysql> grant all privileges on ambari.* to 'ambari'@'localhost' identified by '1234';

mysql> grant all privileges on ambari.* to 'ambari'@'%' identified by '1234';

mysql> grant all privileges on ambari.* to 'ambari'@'192.168.30.145' identified by '1234';

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> quit;
Bye

三、ambari的安装

[root@hadoop1 opt]# yum install ambari-server

[root@hadoop1 opt]# ambari-server setup

解决方案：

#除了server端要升级mysql-connetor,agent端也需要安装，切记。
[root@hadoop1 opt]# yum install mysql-connector-java -y
[root@hadoop1 opt]# cd /usr/share/java/
[root@hadoop1 java]# ls

[root@hadoop1 opt]# ambari-server setup

[root@hadoop1 mysql]#  ambari-server setup

设置Setup-JDBC

[root@hadoop1 opt]# ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar
Using python  /usr/bin/python
Setup ambari-server
Copying /usr/share/java/mysql-connector-java.jar to /var/lib/ambari-server/resources

JDBC driver was successfully initialized.
Ambari Server 'setup' completed successfully.

启动ambari，默认端口是8080，如果端口被占用修改配置文件 /etc/ambari-server/conf/ambari.properties
默认情况下配置文件中没有这个选项，添加上就可以。

client.api.port=8090

然后启动

[root@hadoop1 opt]# ambari-server start

在浏览器中的打开ambari的访问页面，用户名和密码默认为admin。
