ubuntu安装cloudera-managera

前端之家收集整理的这篇文章主要介绍了ubuntu安装cloudera-managera前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

第一步:准备3台虚拟机

cloudera-scm server 内存分配4G
cloudera-scm agent 内存分配2G
cloudera-scm agent 内存分配2G

分别修改虚拟的hostname和hosts文件

指令:sudo vim /etc/hosts

127.0.0.1       localhost
#127.0.1.1      ubuntu-14.04-Server     ubuntu-14  #一定要注释掉
10.0.83.201 CDH.aboutyun.com CDH
10.0.83.202 CDH1.aboutyun.com CDH1
10.0.83.173 CDH2.aboutyun.com CDH2
指令:sudo vim /etc/hostname 分别修改3台虚拟机的主机名
CHD.aboutyun.com
指令:sudo reboot 重启虚拟机

第二步:每台机器安装jdk环境

并查看java版本 java -version

第三步:关闭防火墙

指令:sudo apt-get install ufw

指令:sudo ufw disable

指令:sudo ufw status

第四步:三台机器都安装ssh

指令:sudo apt-get install ssh

指令:sudo mv /usr/bin/host /usr/bin/host.bak

指令:echo 0 > /proc/sys/vm/swappiness

第五步:下载安装cloudera-manager

下载网址:http://archive.cloudera.com/cm5/installer

cd到目录/usr/cloudera

指令:wget -r -O cloudera-manager-installer.bin "http://archive.cloudera.com/cm5/installer/latest/cloudera-manager-installer.bin"

指令:chmod u+x cloudera-manager-installer.bin 改变执行权限

指令:sudo ./cloudera-manager-installer.bin 安装

安装错误

在这里安装时出现了点问题:


首先需要执行指令:vim /var/log/cloudera-manager-installer/2.refresh-repo.log 查看安装日志

有如下错误

Err http://security.ubuntu.com trusty-security/main amd64 Packages             404  Not Found [IP: 91.189.91.26 80]
Fetched 1,107 kB in 11s (92.8 kB/s) 
W: GPG error: http://extras.ubuntu.com trusty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 16126D3A3E5C1192
W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/trusty-security/main/binary-amd64/Packages  404  Not Found [IP: 91.189.91.26 80]
W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/trusty-security/main/binary-i386/Packages  Hash Sum mismatch
E: Some index files Failed to download. They have been ignored,or old ones used instead.

搜寻资料显示是源的故障:指令sudo apt-get update 会报同样的错误

所以清空源缓存:指令:sudo rm -vfr /var/lib/apt/lists/*

更改源:指令sudo vim /etc/apt/sources.list

将之前的源去掉,或者添加 # 到源前面。

然后添加下来源 ,并且sudo apt-get update 和 sudo apt-get upgrade

deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

然后再次安装 指令:sudo ./cloudera-manager-installer.bin

第六步:登陆cloudera

win7上登陆 http://10.0.83.201:7180 账号密码都是admin

根据提示点“继续”

直到搜索,输入:10.0.83.173,10.0.83.201,10.0.83.202

到集群安装又遇到新问题如下:


因为设置密码登陆时是需要填写root的登陆密码

遇见问题:


问题原因是步骤1中忘记分别修改三台主机名为:CDH.aboutyun.com;CDH1.aboutyun.com;CDH2.aboutyun.com。并注释掉127.0.1.1那一行

第七步:安装MysqL

因为在配置cloudera-manager 各组件需要使用对应的数据库


首先安装MysqL 指令:sudo apt-get install MysqL-server

创建名为hive_home的数据库MysqL>create database hive_database;

创建hive_root的用户密码为312715289:grant all on hive_database.* to hive_root@localhost identified by "312715289";


安装jdbc 指令:sudoapt-getinstalllibMysqL-java

不过我们使用cloudera-manager嵌入式数据库

接下来遇见问题:

Unknown host 'ubuntu-14.04-Server:7432'. Unable to find it from host...
这里正常情况应该是CDH.aboutyun.com:7432,这是一个bug,好像在用VPN远程登录安装的时候会出现,解决方法修改/etc/cloudera-scm-server/db.mgmt.properties文件,把所有:7432都改成CDH.aboutyun.com:7432,注意不能用localhost,修改完重启服务: sudo service cloudera-scm-server restart,然后在页面返回上一步,如果提示找不到网页时,直接刷新页面到其显示为止

指令:sudo vim/etc/cloudera-scm-server/db.mgmt.properties

修改所有ubuntu-14.04-Server:7432为CDH.aboutyun.com:7432

指令:sudo service cloudera-scm-server restart
