CDH（Cloudera Distribution Hadoop）
官方教程 http://www.cloudera.com/content/cloudera/en/downloads/cdh/
在线安装
从网站下的one-click-install目录选择对应的Linux系统版本号，自动添加安装源和进行相关配置，然后根据机器的功能进行下面的安装
Resource Manager host :
sudo apt-get update; sudo apt-get install hadoop-yarn-resourcemanager
NameNode host running:
sudo apt-get install hadoop-hdfs-namenode
Secondary NameNode host (if used) running:
sudo apt-get install hadoop-hdfs-secondarynamenode
All cluster hosts except the Resource Manager running:
sudo apt-get install hadoop-yarn-nodemanager hadoop-hdfs-datanode hadoop-mapreduce
One host in the cluster running:
sudo apt-get install hadoop-mapreduce-historyserver hadoop-yarn-proxyserver
All client hosts running:
sudo apt-get install hadoop-client
离线安装
http://archive.cloudera.com/cdh5/cdh/5/ 独立功能包下载，不推荐，需要时间识别文件版本和安装到对应目录
http://archive.cloudera.com/cdh5/parcels/ 完整功能包 在Cloudera Manager中使用来部署
下载好相应系统版本的.parcel文件后，拷贝到本地的parcel源目录下（由Cloudera Manager Server指定，默认是/opt/cloudera/parcel-repo）
然后打开同目录下的mainfest.json（也要拷贝到其中）文件，从里面搜索到与你下载的包同名的部分，然后根据其hash值创建一个后缀名为.sha的文本文件，名字与下载的parcel同名，然后将sha文件也拷贝到本地parcel源的目录下。例如：
# cat > CDH-4.3.0-1.cdh4.3.0.p0.22-el6.parcel.sha df5cc61b2d257aaf625341f709a4f8e09754038a
总之，要确保/opt/cloudera/parcel-repo下面有三个文件：
CDH-4.3.0-1.cdh4.3.0.p0.22-el6.parcel
mainfest.json
CDH-4.3.0-1.cdh4.3.0.p0.22-el6.parcel.sha
cloudera-manager安装
离线安装文件目录http://archive.cloudera.com/cm5/cm/5/
下载tar.gz 解压
sudo tar -zxvf cloudera-manager-trusty-cm5.2.1_amd64.tar.gz -C /opt/cloudera
添加用户
sudo useradd --system --home=/opt/cloudera/cm-5.2.1/run/cloudera-scm-server --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm
配置服务器ip和端口（单机测试无须此步骤）
修改/etc/cloudera-scm-agent/config.ini 下面的 server_port 和 server_host
配置mysql数据库
从http://www.mysql.com/products/connector/下载JDBC，复制到CM目录下./share/cmf/lib
sudo cp /home/manhua/下载/mysql-connector-java-5.1.34-bin.jar ./share/cmf/lib/
生成数据库
sudo apt-get install mysql-server
sudo ./share/cmf/schema/scm_prepare_database.sh mysql scm -h localhost -u root -p root
install ssh
create no password sudo user
https://help.ubuntu.com/community/RootSudo
sudo visudo ,add the following to the END of the file
<username> ALL=NOPASSWD: ALL
由于我用的是linux mint，所以在安装时它会拒绝，需要修改lsb
sudo gedit /etc/lsb-release
DISTRIB_ID=LinuxMint DISTRIB_RELEASE=17.1 DISTRIB_CODENAME=rebecca DISTRIB_DESCRIPTION="Linux Mint 17.1 Rebecca"
DISTRIB_ID=Ubuntu DISTRIB_RELEASE=14.04 DISTRIB_CODENAME=trusty DISTRIB_DESCRIPTION="Linux Mint 17.1 Rebecca"
启动
sudo ./etc/init.d/cloudera-scm-server start
其中对于agents，scp复制CM的整个目录到相同位置后，运行
sudo ./etc/init.d/cloudera-scm-agent start
启动 Cloudera Manager 管理控制台
http://localhost:7180
用户名密码均为admin
然后用上面下载的cdh的parcel文件来安装
