--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/
1.本地cdh4 搭建/
1、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
2、安装createrepo
--Createrepo用于创建本地源。
sudo yum install yum-utils createrepo
3、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。
4: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。
2.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
