  1. 1. Hadoop 安装

Hadoop 安装

–hadoop文件位置：
log目录 :

/var/log/hadoop-hdfs 
/var/log/hadoop-mapreduce 
/var/log/hbase 
/var/log/hive 
/var/log/hive
/var/log/impala

安装目录：

/usr/lib

启动命令目录：

/etc/init.d/

配置文件目录：

/etc/hadoop/conf 
/etc/hbase/conf
/etc/hive/conf 
/etc/impala/conf

环境变量：

/etc/profile

让/etc/profile文件修改后立即生效 ,可以使用如下命令:

source /etc/profile

node配置：

/etc/hosts

资源库位置 ：

/etc/yum.repos.d/

#本地cdh4 搭建/

##安装httpd服务,作用：用browser查看本地库
–安装httpd

yum install httpd

–启动httpd
vi /etctpdtpd.conf (配置文件)

service httpd start 
service httpd stop 
service httpd restart

–关闭防火墙

service iptables status 
service iptables stop

–浏览器查看
http://ip地址

##安装createrepo
–Createrepo用于创建本地源。

sudo yum install yum-utils createrepo

##搭建本地源
–下载cloudera-manager.repo,cloudera-cdh4.repo到/etc/yum.repos.d/目录下

cd /etc/yum.repos.d/
wget http://archive.cloudera.com/cm4/redhat/6/x86_64/cm/cloudera-manager.repo 
wget http://archive.cloudera.com/cdh4/redhat/6/x86_64/cdh/cloudera-cdh4.repo

–将远程源的RPM包同步到本地的httpd服务目录

cd /var/www/html/ 
reposync -r cloudera-manager 
reposync -r cloudera-cdh4

–生成或刷新：RPMS，和一个放依赖关系等信息的文件夹repodata。

cd /var/www/html/cloudera-manager 
createrepo . 
cd /var/www/html/cloudera-cdh4 
createrepo .

至此，CDH4本地源搭建完成。

##本地源的使用
–修改cloudera-manager.repo中的baseurl修改指向本地局域网的服务器
将baseurl=http://archive.cloudera.com/cm4/redhat/6/x86_64/cm/4/ 改为：
baseurl=http://172.16.2.52/cloudera-manager/
–修改cloudera-cdh4.repo中的baseurl修改指向本地局域网的服务器
将baseurl=http://archive.cloudera.com/cdh4/redhat/6/x86_64/cdh/4/ 改为：
baseurl=http://172.16.2.52/cloudera-cdh4/
baseurl的地址是服务器地址+放置RPM包的目录名，结构如下图：里面有一个放RPM包的文件夹RPMS，和一个放依赖关系等信息的文件夹repodata。

#cloudera manager安装
–安装

sudo yum install cloudera-manager-daemons 
sudo yum install cloudera-manager-server 
sudo yum install cloudera-manager-server-db 
sudo yum install cloudera-manager-agent

–启动

service cloudera-scm-server start 
service  cloudera-manager-server-db  start 
service cloudera-scm-agent start

#cdh4 安装
//安装 装CDH4

yum install hadoop-0.20-mapreduce-jobtracker hadoop-0.20-mapreduce-tasktracker
yum install hadoop-hdfs-namenode
yum install hadoop-hdfs-datanode
yum install hadoop-0.20-conf-pseudo
sudo -u hdfs hdfs namenode -format

–启动hdfs

for x in `cd /etc/init.d ; ls hadoop-hdfs-*` ; do sudo service $x start ; done

#安装 hive
参考资料：http://heylinux.com/archives/2456.html
–安装hive

sudo yum install hive hive-metastore hive-server

–安装mysql

sudo yum install mysql mysql-server mysql-devel
service mysqld start

–安装mysql连接驱动

sudo yum install mysql-connector-java
ln -s /usr/share/java/mysql-connector-java.jar /usr/lib/hive/lib/mysql-connector-java.jar

–设置root密码

sudo /usr/bin/mysql_secure_installation

根据提示输入密码

01    [...]    
02    Enter current password for root (enter for none):    
03    OK, successfully used password, moving on...    
04    [...]    
05    Set root password? [Y/n] y    
06    New password:hadoophive    
07    Re-enter new password:hadoophive    
08    Remove anonymous users? [Y/n] Y    
09    [...]    
10    Disallow root login remotely? [Y/n] N    
11    [...]    
12    Remove test database and access to it [Y/n] Y    
13    [...]    
14    Reload privilege tables now? [Y/n] Y    
15    All done!

–进入mysql 依次执行

GRANT  ALL PRIVILEGES ON metastore.* TO 'hive'@'%';
GRANT  ALL PRIVILEGES ON metastore.* TO 'hive'@'localhost';
FLUSH PRIVILEGES;
quit;

–启动hive
