篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Ubuntu14.04离线安装CDH5.6.0相关的知识，希望对你有一定的参考价值。

官方安装文档：http://www.cloudera.com/documentation/enterprise/5-6-x/topics/installation.html
相关包的下载地址：
Cloudera Manager地址：http://archive.cloudera.com/cm5/cm/5/
CDH安装包地址：http://archive.cloudera.com/cdh5/parcels/5.6.0/

由于我们的操作系统为ubuntu14.04，需要下载以下文件： 

CDH-5.6.0-1.cdh5.6.0.p0.45-trusty.parcel
CDH-5.6.0-1.cdh5.6.0.p0.45-trusty.parcel.sha1 
manifest.json

全程采用root安装

机器配置

1. 三台机器的ip和名字为

  • 192.168.10.236 hadoop-1 (内存16G)
  • 192.168.10.237 hadoop-2 (内存8G)
  • 192.168.10.238 hadoop-3 (内存8G)

我们将hadoop-1作为主节点

2. 配置/etc/hosts,使节点间通过 hadoop-X 即可访问其他节点

3. 配置主节点root免密码登录到其他节点（不需要从节点到主节点）

3.1 在hadoop-1上执行ssh-keygen -t rsa -P ''生成无密码密钥对

3.2 将公钥添加到认证文件中：cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys

3.3 将认证文件拷贝到hadoop-2和hadoop-3的/root/.ssh/目录下，使主节点免密码访问从节点

4. 配置jdk

4.1 安装oracle-j2sdk1.7版本(主从都要,根据CDH版本选择对应的jdk)

$ apt-get install oracle-j2sdk1.7
$ update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-7-oracle-cloudera/bin/java 300
$ update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java-7-oracle-cloudera/bin/javac 300

4.2 $ vim /etc/profile

在末尾添加

export JAVA_HOME=/usr/lib/jvm/java-7-oracle-cloudera
export JRE_HOME=${JAVA_HOME}/jre 
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=$PATH:${JAVA_HOME}/bin:{JRE_HOME}/bin:$PATH

4.3 $ vim /root/.bashrc

在末尾添加

source /etc/profile

5. 安装MariaDB-5.5(兼容性请查看官方文档，具体可参照ubuntu14.04 安装MariaDB10.0并允许远程访问)

5.1 执行$ apt-get install mariadb-server-5.5

5.2 数据库设置（官方建议设置）

$ vim /etc/mysql/my.cnf

下面是官方建议的配置

[mysqld]
transaction-isolation = READ-COMMITTED
# Disabling symbolic-links is recommended to prevent assorted security risks;
# to do so, uncomment this line:
# symbolic-links = 0

key_buffer = 16M
key_buffer_size = 32M
max_allowed_packet = 32M
thread_stack = 256K
thread_cache_size = 64
query_cache_limit = 8M
query_cache_size = 64M
query_cache_type = 1

max_connections = 550
#expire_logs_days = 10
#max_binlog_size = 100M

#log_bin should be on a disk with enough free space. Replace '/var/lib/mysql/mysql_binary_log' with an appropriate path for your system
#and chown the specified folder to the mysql user.
log_bin=/var/lib/mysql/mysql_binary_log

binlog_format = mixed

read_buffer_size = 2M
read_rnd_buffer_size = 16M
sort_buffer_size = 8M
join_buffer_size = 8M

# InnoDB settings
innodb_file_per_table = 1
innodb_flush_log_at_trx_commit  = 2
innodb_log_buffer_size = 64M
innodb_buffer_pool_size = 4G
innodb_thread_concurrency = 8
innodb_flush_method = O_DIRECT
innodb_log_file_size = 512M

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

重启服务，service mysql restart

5.3 创建相关数据库

进入mysql命令行：$ mysql -u root -p
进入mysql命令行后，直接复制下面的整段话并粘贴：
create database amon DEFAULT CHARACTER SET utf8;
grant all on amon.* TO 'amon'@'%' IDENTIFIED BY 'amon_password';
grant all on amon.* TO 'amon'@'CDH' IDENTIFIED BY 'amon_password';
create database smon DEFAULT CHARACTER SET utf8;
grant all on smon.* TO 'smon'@'%' IDENTIFIED BY 'smon_password';
grant all on smon.* TO 'smon'@'CDH' IDENTIFIED BY 'smon_password';
create database rman DEFAULT CHARACTER SET utf8;
grant all on rman.* TO 'rman'@'%' IDENTIFIED BY 'rman_password';
grant all on rman.* TO 'rman'@'CDH' IDENTIFIED BY 'rman_password';
create database hmon DEFAULT CHARACTER SET utf8;
grant all on hmon.* TO 'hmon'@'%' IDENTIFIED BY 'hmon_password';
grant all on hmon.* TO 'hmon'@'CDH' IDENTIFIED BY 'hmon_password';
create database hive DEFAULT CHARACTER SET utf8;
grant all on hive.* TO 'hive'@'%' IDENTIFIED BY 'hive_password';
grant all on hive.* TO 'hive'@'CDH' IDENTIFIED BY 'hive_password';
create database oozie DEFAULT CHARACTER SET utf8;
grant all on oozie.* TO 'oozie'@'%' IDENTIFIED BY 'oozie_password';
grant all on oozie.* TO 'oozie'@'CDH' IDENTIFIED BY 'oozie_password';
create database metastore DEFAULT CHARACTER SET utf8;
grant all on metastore.* TO 'hive'@'%' IDENTIFIED BY 'hive_password';
grant all on metastore.* TO 'hive'@'CDH' IDENTIFIED BY 'hive_password';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'gaoying' WITH GRANT OPTION;
flush privileges;

5.4 安装MariaDB jdbc 驱动

$ apt-get install libmysql-java

5.5 使用cloudera脚本在mysql中进行相关配置：（先完成第6.1后再配置）

$ /opt/cloudera-manager/cm-5.6.0/share/cmf/schema/scm_prepare_database.sh mysql -uroot -p --scm-host localhost scm scm scm_password

6. 安装Cloudera Manager Server 和 Agents

6.1 把安装包解压到主节点

$ mkdir /opt/cloudera-manager
将下载好的cloudera-manager-trusty-cm5.6.0_amd64.tar.gz解压到/opt/cloudera-manager

6.2 创建用户

$ sudo useradd --system --home=/opt/cloudera-manager/cm-5.6.0/run/cloudera-scm-server --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm
//--home 指向你cloudera-scm-server的路径

6.3 创建cloudera manager server的本地数据存储目录(主)

$ sudo mkdir /var/log/cloudera-scm-server
$ sudo chown cloudera-scm:cloudera-scm /var/log/cloudera-scm-server

6.4 在每个Cloudera Manager Agent 节点配置server_host(主从都要)

$ vim /opt/cloudera-manager/cm-5.6.0/etc/cloudera-scm-agent/config.ini
//吧server_host改成主节点名称
server_host=hadoop-1

6.5 将cloudera-manager发送到各从节点对应的目录下(即/opt)

$ scp -r /opt/cloudera-manager root@hadoop-2:/opt

6.6 创建Parcel目录

6.6.1 在主节点上：

创建安装包目录 mkdir -p /opt/cloudera/parcel-repo

将CHD5相关的Parcel包放到主节点的/opt/cloudera/parcel-repo/目录中

CDH-5.6.0-1.cdh5.6.0.p0.45-trusty.parcel
CDH-5.6.0-1.cdh5.6.0.p0.45-trusty.parcel.sha1 
manifest.json

最后将CDH-5.6.0-1.cdh5.6.0.p0.45-trusty.parcel.sha1，重命名为CDH-5.6.0-1.cdh5.6.0.p0.45-trusty.parcel.sha，这点必须注意，否则，系统会重新下载CDH-5.6.0-1.cdh5.6.0.p0.45-trusty.parcel.sha1文件。

6.6.2 在从节点上：mkdir -p /opt/cloudera/parcels

6.7 在各节点上安装依赖

用apt-get install安装以下依赖

lsb-base
psmisc
bash
libsasl2-modules
libsasl2-modules-gssapi-mit
zlib1g
libxslt1.1
libsqlite3-0
libfuse2
fuse-utils or fuse
rpcbind

6.8 启动server和agent

主节点上：

/opt/cloudera-manager/cm-5.6.0/etc/init.d/cloudera-scm-server start
/opt/cloudera-manager/cm-5.6.0/etc/init.d/cloudera-scm-agent stop

从节点上:

/opt/cloudera-manager/cm-5.6.0/etc/init.d/cloudera-scm-agent stop

若启动出错，可以查看/opt/cloudera-manager/cm-5.6.0/log里的日志
若没错，则等待几分钟后，在浏览器访问Cloudera Manager Admin Console,我的主节点ip为192.168.10.236，那么访问http://192.168.10.236:7180,默认的用户名和密码为admin

8 简单测试

8.1 在hadoop上执行MapReduce job

在主节点终端执行

sudo -u hdfs hadoop jar \\
/opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar \\
pi 10 100

终端会输出任务执行情况
