一、准备工作
1、系统环境
系统centos6.5
节点三台:
192.168.1.130
192.168.1.131
192.168.1.132
1、所有节点关闭防火墙
service iptables stop
chkconfig iptables off
2、所有节点关闭selinux
3、主机名和hosts文件
127.0.0.1 localhost.localdomain localhost
192.168.1.130 bigdata-cdh01.ibeifeng.com bigdata-cdh01
192.168.1.131 bigdata-cdh02.ibeifeng.com bigdata-cdh02
192.168.1.132 bigdata-cdh03.ibeifeng.com bigdata-cdh03
4、创建一个普通用户,所有节点
username:beifeng passwd:beifeng
[root@bigdata-cdh01 ~]# useradd beifeng
[root@bigdata-cdh01 ~]# passwd beifeng
[root@bigdata-cdh02 ~]# useradd beifeng
[root@bigdata-cdh02 ~]# passwd beifeng
[root@bigdata-cdh03 ~]# useradd beifeng
[root@bigdata-cdh03 ~]# passwd beifeng
5、配置beifneg用户的sudo权限
vim /etc/sudoers #所有节点执行
beifeng ALL=(root)NOPASSWD:ALL #写入此行
:wq! #保存退出
6、切换到beifeng用户
su - beifeng
7、禁用ipv6
sudo vim /etc/modprobe.d/dist.conf #写入一下两行,所有节点
alias net-pf-10 off
alias ipv6 off
8、所有及节点安装jdk
sudo rpm -qa |grep java #先查看系统是否自带jdk,如果有就卸载
然后安装jdk,比较简单;
9、设置文件描述符
vim /etc/security/limits.conf #写入以下4行
* hard nofile 65535
* soft nofile 65535
* hard nproc 65535
* soft nproc 65535
2、系统环境2
1、时间同步
在内网找一台作为时间服务器,所有的机器与这台机器时间进行定时的同步,比如每十分钟同步一次时间;
这里用CDH1做时间服务器;
##检查是否安装
[root@bigdata-cdh01 ~]# rpm -qa |grep ntp
ntp-4.2.6p5-15.el6.centos.x86_64
fontpackages-filesystem-1.41-1.1.el6.noarch
ntpdate-4.2.6p5-15.el6.centos.x86_64
##配置:
vim /etc/ntp.conf
#第一处
restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap #去掉此行的注释,并改为集群网段
#第二处,注释掉下面几行
#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
#第三处,添加下面两行
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10
##设置同步更新本地hwclock
[root@master hadoop-2.5.0]# vim /etc/sysconfig/ntpd
# Drop root to id 'ntp:ntp' by default.
SYNC_HWCLOCK=yes #添加此行
OPTIONS="-u ntp:ntp -p /var/run/ntpd.pid -g"
##启动ntpd
[root@master hadoop-2.5.0]# service ntpd status
[root@master hadoop-2.5.0]# service ntpd start
[root@master hadoop-2.5.0]#chkconfig ntpd on
在CDH2、CDH3上设置同步时间脚本:
#CDH2
[root@slave1 hadoop-2.5.0]# crontab -l
#去master同步时间,10分钟1次
0-59/10 * * * * /usr/sbin/ntpdate bigdata-cdh01.ibeifeng.com
#CDH3
[root@slave2 hadoop-2.5.0]# crontab -l
#去master同步时间,10分钟1次
0-59/10 * * * * /usr/sbin/ntpdate bigdata-cdh01.ibeifeng.com
2、配置ssh互信
3、重启所有节点
二、安装CDH
离线rpm安装,CDH5.3.6版本;
1、安装CM的准备
网站:
http://archive.cloudera.com/cm5/
cm-5.3.6bin文件:
http://archive.cloudera.com/cm5/installer/5.3.6/
cm-5.3.6依赖rpm包:
http://archive.cloudera.com/cm5/redhat/6/x86_64/cm/5.3.6/RPMS/x86_64/
1、上传安装包
[beifeng@bigdata-cdh01 softwares]$ ls
cdh-5.3.6 cm-5.3.6 postgresq-libs repo-libs
[beifeng@bigdata-cdh01 softwares]$ tree ./
./
├── cdh-5.3.6

└── python-deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm
2、搭建yum本地源服务器
说明:本地安装一个http服务器,将软件放进网站目录下去,安装的时候通过URL寻找;
安装http:
[beifeng@bigdata-cdh01 ~]$ sudo rpm -qa |grep http
httpd-tools-2.2.15-29.el6.centos.x86_64
httpd-2.2.15-29.el6.centos.x86_64
[beifeng@bigdata-cdh01 ~]$ sudo service httpd start
正在启动 httpd: [确定]
[beifeng@bigdata-cdh01 ~]$ sudo service httpd status
httpd (pid 2634) 正在运行...
[beifeng@bigdata-cdh01 ~]$ sudo chkconfig httpd on
创建软件存放目录:
[beifeng@bigdata-cdh01 ~]$ cd /var/www/html/
[beifeng@bigdata-cdh01 html]$ sudo mkdir -p cm5/redhat/6/x86_64/cm/5/RPMS/x86_64/
[beifeng@bigdata-cdh01 html]$ ls
cm5
[beifeng@bigdata-cdh01 html]$ tree
.
└── cm5
└── redhat
└── 6
└── x86_64
└── cm
└── 5
└── RPMS
└── x86_64
将cm软件包放进网站目录:
##
[beifeng@bigdata-cdh01 cm-5.3.6]$ pwd
/opt/softwares/cm-5.3.6
[beifeng@bigdata-cdh01 cm-5.3.6]$ sudo mv ./cloudera-manager-installer.bin ../ #先把cm目录中的bin文件移出去
##
[beifeng@bigdata-cdh01 x86_64]$ pwd
/var/www/html/cm5/redhat/6/x86_64/cm/5/RPMS/x86_64
[beifeng@bigdata-cdh01 x86_64]$ sudo mv /opt/softwares/cm-5.3.6/* ./
3、修改hosts文件
[beifeng@bigdata-cdh01 cm-5.3.6]$ sudo vim /etc/hosts
192.168.1.130 archive.cloudera.com #cdh1添加此行,我这里为了测试,本地hosts也添加了此行
4、准备repo文件
[beifeng@bigdata-cdh01 yum.repos.d]$ pwd
/etc/yum.repos.d
[beifeng@bigdata-cdh01 yum.repos.d]$ sudo rm -rf ./*
[beifeng@bigdata-cdh01 yum.repos.d]$ sudo touch cloudera-manager.repo
[beifeng@bigdata-cdh01 yum.repos.d]$ cat cloudera-manager.repo
[cloudera-manager]
# Packages for Cloudera Manager, Version 5, on RedHat or CentOS 6 x86_64
name=Cloudera Manager
baseurl=http://archive.cloudera.com/cm5/redhat/6/x86_64/cm/5/
gpgkey=http://archive.cloudera.com/cm5/redhat/6/x86_64/cm/RPM-GPG-KEY-cloudera
gpgcheck = 1
RPM-GPG-KEY-cloudera #这个文件手动生成一下
https://archive.cloudera.com/cm5/redhat/6/x86_64/cm/RPM-GPG-KEY-cloudera #在网上下载此文件,放到/var/www/html/cm5/redhat/6/x86_64/cm/下面
2、安装CM
###
[beifeng@bigdata-cdh01 postgresq-libs]$ pwd
/opt/softwares/postgresq-libs
[beifeng@bigdata-cdh01 postgresq-libs]$ sudo chmod u+x ./*
[beifeng@bigdata-cdh01 postgresq-libs]$ sudo rpm -ivh *.rpm
Preparing... ########################################### [100%]
1:postgresql-libs ########################################### [ 33%]
2:postgresql ########################################### [ 67%]
3:postgresql-server ########################################### [100%]
###
安装CM:
[beifeng@bigdata-cdh01 repo-libs]$ pwd
/opt/softwares/repo-libs
[beifeng@bigdata-cdh01 repo-libs]$ ls
createrepo-0.9.9-18.el6.noarch.rpm deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm python-deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm
[beifeng@bigdata-cdh01 repo-libs]$ sudo rpm -ivh ./*.rpm
Preparing... ########################################### [100%]
1:deltarpm ########################################### [ 33%]
2:python-deltarpm ########################################### [ 67%]
3:createrepo ########################################### [100%]
[beifeng@bigdata-cdh01 5]$ pwd
/var/www/html/cm5/redhat/6/x86_64/cm/5
[beifeng@bigdata-cdh01 5]$ sudo createrepo . #当前目录下会生成一个文件夹:repodata
[beifeng@bigdata-cdh01 postgresq-libs]$ cd /opt/softwares/
[beifeng@bigdata-cdh01 softwares]$ sudo chmod +x cloudera-manager-installer.bin
[beifeng@bigdata-cdh01 softwares]$ sudo ./cloudera-manager-installer.bin #接着会出现一个界面
Next-->Next-->Yes-->Next-->Yes ...
如果报错了,日至都在/var/log/cloudera-manager-installer
###
等待安装完成后:
[beifeng@bigdata-cdh01 ~]$ netstat -ntlp |grep 7180
(No info could be read for "-p": geteuid()=501 but you should be root.)
tcp 0 0 0.0.0.0:7180 0.0.0.0:* LISTEN -
浏览器打开:hostname(ip)+port
账号/密码:admin
3、安装CDH
此时要准备CDH的包
网站:http://archive.cloudera.com/cdh5/parcels/5.3.6/
下载以下两个包:
CDH-5.3.6-1.cdh5.3.6.p0.11-el6.parcel
CDH-5.3.6-1.cdh5.3.6.p0.11-el6.parcel.sha1
创建/opt/cloudera/parcel-repo 可能CM安装时已经自动创建过了;
将上面两个包mv进/opt/cloudera/parcel-repo:
[beifeng@bigdata-cdh01 parcel-repo]$ ls
CDH-5.3.6-1.cdh5.3.6.p0.11-el6.parcel CDH-5.3.6-1.cdh5.3.6.p0.11-el6.parcel.sha1
[beifeng@bigdata-cdh01 parcel-repo]$ sudo mv CDH-5.3.6-1.cdh5.3.6.p0.11-el6.parcel.sha1 ./CDH-5.3.6-1.cdh5.3.6.p0.11-el6.parcel.sha #去掉末尾的1
##
查看cm的状态,
[beifeng@bigdata-cdh01 ~]$ sudo service cloudera-scm-server status
cloudera-scm-server (pid 3151) 正在运行...
##
修改CDH01 yum文件,并分发:
[beifeng@bigdata-cdh01 ~]$ sudo cat /etc/yum.repos.d/cloudera-manager.repo #内容改为如下
[cloudera-manager]
name=Cloudera Manager
baseurl=http://bigdata-cdh01.ibeifeng.com/cm5/redhat/6/x86_64/cm/5/
gpgkey=http://bigdata-cdh01.ibeifeng.com/cm5/redhat/6/x86_64/cm/RPM-GPG-KEY-cloudera
gpgcheck=1
CDH02: sudo rm -rf /etc/yum.repos.d/*
CDH03: sudo rm -rf /etc/yum.repos.d/*
[beifeng@bigdata-cdh01 ~]$ sudo scp -r /etc/yum.repos.d/cloudera-manager.repo root@bigdata-cdh02:/etc/yum.repos.d/
[beifeng@bigdata-cdh01 ~]$ sudo scp -r /etc/yum.repos.d/cloudera-manager.repo root@bigdata-cdh03:/etc/yum.repos.d/
输入主机名,搜索主机:
然后,等待安装完成;
等待分配:
###
CDH01 的hosts文件中,注释掉下面一行:
192.168.1.130 archive.cloudera.com
###
所有节点关闭swap(可以切换到root执行):
echo 0 > /proc/sys/vm/swappiness
sysctl vm/swappiness
echo 'vm.swappiness = 0' >> /etc/sysctl.conf
sysctl -p
###
所有节点执行:
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo 'echo never > /sys/kernel/mm/transparent_hugepage/defrag' >> /etc/rc.local
继续:
点击左上角Logo先离开;
4、安装CMS监控服务
CDH2、CDH3节点:
sudo crontab -e
0-59/10 * * * * sh /home/crontab/ntp.sh
##/home/crontab/ntp.sh
#!/bin/bash
#
/sbin/service ntpd stop
/usr/sbin/ntpdate bigdata-cdh01.ibeifeng.com
/sbin/service ntpd start
