hadoop离线安装(二）

3、制作本地源

（1）安装本地源制作相关工具（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）
复制代码
[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/
复制代码
上面就创建好了主机上的文件，然后可以通过下面命令清楚一下yum的缓存就可以了

[root@master ambari]# yum clean all
[root@master ambari]# yum makecache
[root@master ambari]# yum repolist
（3）将创建好的文件拷贝到子节点（主服务器）
复制代码
[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

四、安装ambari-server

经过不断的安装，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，根据个人需求选择。建议使用自带的postgresql来配置数据库，这样在后面安装过程中不会出现问题，如果使用其它数据库，请参考其它教程来设置

1、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
复制代码
[root@master yum.repos.d]# yum -y install ambari-server
[root@master yum.repos.d]# ambari-server setup

复制代码
（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

2、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）登录进mysql，初始化设置root密码
复制代码
[root@master ~]# mysql -uroot

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

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

远程登录
#mysql -uroot -h ip(远程的ip地址) -p
[root@master yum.repos.d]# yum -y install ambari-server
复制代码
（4）登录mysql，执行下面的语句
复制代码
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;
复制代码
（5）简历mysql与ambari-server的连接
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
添加server.jdbc.driver.path=/usr/share/java/mysql-connector-java.jar
（6）初始化设置ambari-server并启动
复制代码
[root@master ~]# ambari-server setup
下面是配置执行流程，按照提示操作
（1）提示是否自定义设置。输入：y
Customize user account for ambari-server daemon [y/n] (n)? y
（2）ambari-server 账号。
Enter user account for ambari-server daemon (root):
如果直接回车就是默认选择root用户
如果输入已经创建的用户就会显示：
Enter user account for ambari-server daemon (root):ambari
Adjusting ambari-server permissions and ownership...
（3）检查防火墙是否关闭
Adjusting ambari-server permissions and ownership...
Checking firewall...
WARNING: iptables is running. Confirm the necessary Ambari ports are accessible. Refer to the Ambari documentation for more details on ports.
OK to continue [y/n] (y)?
直接回车
（4）设置JDK。输入：3
Checking JDK...
Do you want to change Oracle JDK [y/n] (n)? y
[1] Oracle JDK 1.8 + Java Cryptography Extension (JCE) Policy Files 8
[2] Oracle JDK 1.7 + Java Cryptography Extension (JCE) Policy Files 7
[3] Custom JDK
==============================================================================
Enter choice (1): 3
如果上面选择3自定义JDK,则需要设置JAVA_HOME。输入：/usr/java/jdk1.8.0_161
WARNING: JDK must be installed on all hosts and JAVA_HOME must be valid on all hosts.
WARNING: JCE Policy files are required for configuring Kerberos security. If you plan to use Kerberos,please make sure JCE Unlimited Strength Jurisdiction Policy Files are valid on all hosts.
Path to JAVA_HOME: /usr/java/jdk1.8.0_131
Validating JDK on Ambari Server...done.
Completing setup...
（5）数据库配置。选择：y
Configuring database...
Enter advanced database configuration [y/n] (n)? y
（6）选择数据库类型。输入：3
Configuring database...
==============================================================================
Choose one of the following options:
[1] - PostgreSQL (Embedded)
[2] - Oracle
[3] - MySQL
[4] - PostgreSQL
[5] - Microsoft SQL Server (Tech Preview)
[6] - SQL Anywhere
==============================================================================
Enter choice (3): 3
（7）设置数据库的具体配置信息，根据实际情况输入，如果和括号内相同，则可以直接回车。如果想重命名，就输入。
Hostname (localhost):
Port (3306):
Database name (ambari):
Username (ambari):
Enter Database Password (bigdata):ambarizk123
Re-Enter password: ambarizk123
（8）将Ambari数据库脚本导入到数据库
WARNING: Before starting Ambari Server, you must run the following DDL against the database to create the schema: /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql
Proceed with configuring remote database connection properties [y/n] (y)?
[root@master ~]# ambari-server start
复制代码
3、错误处理
　　如果出现错误，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。如果在处理日志的过程中或者后面安装的过程中出现一些莫名的错误，可以重置的安装。如果上面进行的默认数据库的配置，可以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
　　如果选择的是第二种方式，就需要先执行上面的语句，然后手动将mysql里面创建的数据库进行删除。然后再重新执行第二步的操作

复制代码
[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;
复制代码
　　如果在安装的过程中出现了错误，又想重新安装，可以在ambari-server开启的情况下，执行下面的语句来移除已安装的包，然后再通过不同的情况选择上面两种方式的一种对ambari-server进行重置
