1.安装CDH5.12.x

安装方式

CDH有三种安装方式

parcels 二进制程序包,包含了CDH组件中的依赖版本等信息,可以方便的切换CDH版本,CM调用yum来安装parcels,非常方便.cloudera 推荐使用此种方式安装.
packges rpm方式,缺点是每次只能安装一个版本的rpm,升级回滚都必须重装rpm,因此升级回滚存在包不兼容风险.CM调用yum来安装rpm.不推荐.
tarball 手动下载tar包安装,无法使用yum安装,十分麻烦,而且不支持通过CM在线升级CDH,必须完全手动升级.不建议.
本质上parcels和tarball都是CDH组件的压缩包,但是cloudera对tarball没做支持.
本次以parcels方式安装,不使用CDH自动安装,手动下载parcels包安装
自动安装设置CDH yum资源库,然后可以直接用yum 安装jdk CM agent
手动安装手动安装JDK,下载CDH的CM agent,配置本地yum源安装CM和agent

安装前准备

OS版本 centos6.8
JDK 1.8
python 2.7
安装账户root CM依赖root账户
安装路径 CDH默认路径/opt/cloudera/parcls即可
数据库 mysql,不要使用内置的postgrey

安装步骤

在vbox上安装centos6.8 略
设置ssh互信至少CM节点要能ssh登录其它节点
修改linux系统设置
修改unlimit
关闭iptables
关闭selinux
关闭swape 略
关闭ipv6 略
设置静态ip
修改/etc/hosts,加入CDH所有节点的ip
安装JDK1.8
安装python2.7
安装mysql数据库,并创建数据库和用户
安装ntp
安装CM
安装agent
安装CDH组件

安装过程

修改/etc/hosts

echo "127.0.0.1 localhost" > /etc/hosts
echo "192.168.0.20 CM"     >> /etc/hosts
echo "192.168.0.21 cdh1"   >> /etc/hosts
echo "192.168.0.21 cdh2"   >> /etc/hosts

设置ssh 互信

参CM节点上执行:

[root@CM ~]# ssh-keygen -t rsa -P ''

然后将key复制到其它节点:

ssh-copy-id -i ~/.ssh/id_rsa.pub 192.168.0.21
ssh-copy-id -i ~/.ssh/id_rsa.pub 192.168.0.22

这样CM节点就能ssh到192.168.0.21 192.168.0.22两台机器上了

修改linux 系统设置

1.修改unlimit 略
2.关闭iptables

[root@cdh2 ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]
[root@cdh2 ~]# chkconfig iptables off

3.关闭swap
虚拟机内存不足,略
4.禁用ipv6
这个好麻烦的,略

安装JDK1.8

下载对应版本的JDK1.8,解压到/opt/jdk1.8下
设置java环境变量:
在/etc/profile中设置java环境变量

[root@CM opt]# tar -zxvf jdk-7u80-linux-x64.tar.gz
[root@CM opt]# rm jdk-7u80-linux-x64.tar.gz
[root@CM jdk1.7.0_80]# vi /etc/profile #添加以下内容
JAVA_HOME=/opt/jdk1.7.0_80
PATH=$JAVA_HOME/bin:$PATH

export JAVA_HOME
export PATH

然后执行java 命令测试是否安装成功.

安装python2.7

为了方便,直接安装acconda,再修改系统的python即可.
此外centos6自带的python2.6.6也是可以的

安装mysql/postgreysql数据库

这里选择安装postgreysql,因为mysql的安装包实在太TM的大了

[root@CM ~]# yum isntall postgresql #安装后数据目录在 /var/lib/pgsql
[root@CM ~]# chkconfig --list #找到pg的服务
…
postgresql         0:off    1:off    2:off    3:off    4:off    5:off    6:off

安装ntp

[root@CM ~]# yum install ntp

设置本地yum源

使用yum安装CM时,可以使用cloudera的远程yum源,或者把CM安装包下载到本地,并设置本地yum源.

下载CM安装包
在https://www.cloudera.com/documentation/enterprise/release-notes/topics/cm_vd.html 选择对应版本的CDH CM安装包，下载到/root/下

[root@CM ~]# mkdir -p cloudera_software/RPMS/x86_64
[root@CM ~]# mkdir -p cloudera_software/repodata
[root@CM ~]# cd cloudera_software/RPMS/x86_64

配置本地yum源

[root@CM cloudera_software]# cd /etc/yum.repos.d/ #添加
[cloudera-manager-local]
# Packages for Cloudera Manager, Version 5, on RedHat or CentOS 5 x86_64
name=cloudera-manager-local
baseurl=file:///root/cloudera_software/
gpgkey =file:///root/cloudera_software/RPM-GPG-KEY-cloudera
gpgcheck = 1

下载CDH parcels包

到 https://archive.cloudera.com/cdh5/parcels/ 下载对应版本的parcels包:
这里选择下载https://archive.cloudera.com/cdh5/parcels/latest/ 下的最新的CDH:

https://archive.cloudera.com/cdh5/parcels/latest/CDH-5.12.0-1.cdh5.12.0.p0.29-el6.parcel
https://archive.cloudera.com/cdh5/parcels/latest/CDH-5.12.0-1.cdh5.12.0.p0.29-el6.parcel.sha1
https://archive.cloudera.com/cdh5/parcels/latest/manifest.json

三个文件缺少一个都会导致找不到parcels包,如果新加入了文件,要重启CM进程.

放到/opt/cloudera/parcel-repo下,为什么放这里?因为CDH的parcels包默认就放这里,上图也可以看到.

[root@CM ~]# mkdir -p /opt/cloudera/parcel-repo
[root@CM ~]# mkdir -p /opt/cloudera/parcels

安装CM

使用yum安装CM

[root@CM cloudera_software]# yum install cloudera-manager-agent cloudera-manager-daemons cloudera-manager-server

一开始下成了redhat5的CM包,删除重新下.记得要执行yum clean

上一步完成之后,会有这些文件:

[root@CM x86_64]# ls /etc/cloudera-scm-server
db.properties  log4j.properties

修改其中的db.properties文件:

# Copyright (c) 2012 Cloudera, Inc. All rights reserved.
#
# This file describes the database connection.
#

# The database type
# Currently 'mysql', 'postgresql' and 'oracle' are valid databases.

com.cloudera.cmf.db.setupType=EXTERNAL

启动CM

[root@CM ~]# service cloudera-scm-server start

按照要求设置JAVA_HOME

[root@CM ~]# vi /etc/default/cloudera-scm-server
export JAVA_HOME=/opt/jdk1.7.0_80
然后执行:
[root@CM ~]# service cloudera-scm-server start
Starting cloudera-scm-server:                              [  OK  ]

我有一句mmp不知当讲不当讲!
启动成功了却进不去 192.168.0.20:7180
打开日志一看:

2017-08-20 18:19:25,182 WARN com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread-#0:com.mchange.v2.resourcepool.BasicResourcePool: com.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@a384493 -- Acquisition Attempt Failed!!! Clearing pending acquires. Whil

卧槽,我以为CM会自动创建数据库呢.
再次启动报一堆表找不到,然后CM自动建表了了,可是过一会又挂了

2017-08-20 18:38:48,481 ERROR ParcelUpdateService:com.cloudera.parcel.components.ParcelDownloaderImpl: Error while attempting to retrieve repository info for repo https://archive.cloudera.com/sqoop-connectors/parcels/latest/

CM一直在找远程资源库有没有?!
再次重启,竟然启动了!what the fuck!

安装agent

一上步就直接安装了agent了
安装完需要修改agent的配置文件使其能找到CM

vi /etc/cloudera-scm-agent/config.ini
server_host=192.168.0.20

启动agent

进入CDH

默认使用admin/admin进入

一开始不要选择新加主机,因为还没有装CM的其它服务,如host monitor

由于已经安装了JDK,就不让CM再安装了.

不装单用户

选key

选择CM节点的pub key

配置正确会出现CDH5.12.1的parcels,下一步,直接到parcels分发完成

完成后会显示没有host monitor

创建cmservice数据库create database cmservice owner cdh1 ENCODING 'UTF-8';

这一步死活连不上数据库.查了很多资料,试了很多方法都不行.

添加节点

添加节点的本质是:
在节点上安装agent,然后agent连接cm,那么这个节点就添加进集群了.再由CM分发parcels包,再安装服务

使用CM添加节点

1.

2.

3.选择第二项可以加入自己的yum源

4.自动添加主机时,会设置节点上的yum源

我们到 https://archive.cloudera.com/cm5/redhat/6/x86_64/cm/cloudera-manager.repo 看看这里写的是啥

[cloudera-manager]
# Packages for Cloudera Manager, Version 5, on RedHat or CentOS 6 x86_64                 
name=Cloudera Manager
baseurl=https://archive.cloudera.com/cm5/redhat/6/x86_64/cm/5/
gpgkey =https://archive.cloudera.com/cm5/redhat/6/x86_64/cm/RPM-GPG-KEY-cloudera    
gpgcheck = 1

其实就是cloudera的在线yum源，这个源里的东西是：

其实就是agent和cm的安装包有没有？
鉴于刷新yum元数据实在太慢了，放弃

或者在上面的步骤中设置自己yum源，不用CDH,这样快很多

手动安装agent

这时就不用选择"这样的操作了"，直接在节点上安装agent就好了
从cm上复制agent的安装包,并设置本地yum源并安装

[root@CM cloudera_software]# scp -r /root/cloudera_software root@cdh2:/root/
[root@cdh2 ~]# vi /etc/yum.repos.d/CentOS-Media.repo #添加
[cloudera-manager-local]
# Packages for Cloudera Manager, Version 5, on RedHat or CentOS 5 x86_64
name=cloudera-manager-local
baseurl=file:///root/cloudera_software/
gpgkey =file:///root/cloudera_software/RPM-GPG-KEY-cloudera
gpgcheck = 1
[root@cdh2 ~]# yum install cloudera-manager-agent
这时竟然要联网下一堆依赖，不过很快。怎么创建局域网源？
[root@cdh1 ~]# vi /etc/cloudera-scm-agent/config.ini
server_host=CM
[root@cdh1 ~]# service cloudera-scm-agent start

agent启动完成后，以CM就能看到节点了。

但此时并没有和host monitor连接。
在CM中重启host monitor后就正常了：

远程yum源安装节点

[root@CM cloudera_software]# yum isntall httpd
………..
[root@CM ~]# vi /etc/httpd/conf/httpd.conf
DocumentRoot "/root/cloudera_software"
……
[root@CM ~]# chown -R apache.apache /root/cloudera_software
#删除默认主页
# [root@CM ~]# mv /etc/httpd/conf.d/welcome.conf /etc/httpd/conf.d/welcome.conf.bk
[root@CM ~]# service httpd start

等我会用httpd了再说吧，mzdd!

等节点加入到主机后，选择"向集群添加新主机" "管理当前主机"，选择刚加上的主机，下一步分发parcels。

服务

安装中出现的问题

WARN [770705234@scm-web-1838:tsquery.TimeSeriesQueryService@503]

在安装时添加主机,出现了这个问题,如果只选CM节点,不出现这个问题.

2.

将jdk修改为1.8,之前是1.7
下载postgresql的jdbc驱动到/usr/share/java下,修改/etc/default/cloudera-scm-server的jar路径,添加postgresql的jdbc驱动.并在该文件中export JAVA_HOME
修改日志级别:
export CMF_ROOT_LOGGER="INFO,LOGFILE"

INFO [JvmPauseMonitor:debug.JvmPauseMonitor@236] Detected pause in JVM or host machine (e.g. a stop the world GC, or JVM not scheduled): paused approximately 1039ms: no GCs detected.

修改成jdk1.8,然后并没有任务卵用.
到主机界面设置一下JDK

以上问题,用JAVA1.8重新安装CM AGENT后都解决了!!
