工欲善其事必先利其器,想要学好一门技术首先得有趁手的工具,要想学好大数据技术,还是得有比较好的工具才行。本笔记记录的是安装Cloudera Manager的过程。
CDH的全称是Cloudera’s Distribution Including Apache Hadoop,是hadoop众多发行版本中的一种,是由Cloudera维护,基于稳定版本的Apache Hadoop构建的。而Cloudera Manager是Cloudera用来管理CDH的工具,分为免费版和企业版,目前免费版已经取消了节点数的限制,对于大数据初学者来说是一个非常容易上手的工具。
1.准备工作
安装之前需要做一些准备工作,本笔记记录的是使用虚拟机进行安装的,由于Cloudera Manager(CM)运行hadoop的集群的时候非常耗内存,所以需要给虚拟机足够的内存才能够正常启动hadoop的集群节点。一般来说如果用来安装CM的电脑的内存小于8G的话就不要进行尝试了,因为安装后将无法启动。
1.1下载安装介质
操作系统,本笔记选择的操作系统是CentOS 7,选定操作系统之后在下载CM及CDH的介质的时候就可以选择与此操作系统版本匹配的文件,否则可能会遇到无法解决的问题。
CentOS-7-x86_64-DVD-1708.iso 4G 2017-Sep-06 10:59
需要到Cloudera官方网站上下载安装介质,本笔记需要用到的安装介质如下:
CM主程序安装包,是一个BS架构的系统,可以通过浏览器进行hadoop集群的管理:
cloudera-manager-centos7-cm5.15.2_x86_64.tar.gz 2018-12-10 10:00 801.5 MB
CDH程序的安装包,包括hadoop家族中的hdfs,hive,hbase等安装程序,下面这两个文件都要下载:
CDH-5.15.2-1.cdh5.15.2.p0.3-el7.parcel 2018-12-10 13:31 2.0 GB
CDH-5.15.2-1.cdh5.15.2.p0.3-el7.parcel.sha1 2018-12-10 13:31 41.0 B
CM安装过程中给每个结点要安装的内容,这些安装文件要在CM安装前进行安装,否则CM安装过程中从网上自动下载并安装,会比较耗费时间:
http://archive.cloudera.com/cm5/redhat/7/x86_64/cm/5.15.2/RPMS/x86_64/
cloudera-manager-agent-5.15.2-1.cm5152.p0.2.el7.x86_64.rpm 2018-12-10 09:5 19.4 MB

oracle-j2sdk1.7-1.7.0+update67-1.x86_64.rpm 2018-12-10 09:51 135.5 MB
Mysql:CM支持主流的数据库,本笔记选择的是mysql数据库社区版,
mysql-5.6.42-linux-glibc2.12-x86_64.tar.gz
这个需要到mysql官网上下载,CM支持的数据库版本在下面文档中有详细说明,可以参考下载。
CDH and Cloudera Manager Supported Databases
CM与CDH连接mysql数据库需要jdbc,还需要下载mysql的jdbc驱动文件:
mysql-connector-java-5.1.27-bin.jar
1.2在虚拟机上安装操作系统
本笔记使用的虚拟机版本是VMware 12.5.1,当然也可以使用Virtual Box,两者都是可以的。
虚拟机内存和硬盘的分配如下:
结点名称 内存 硬盘
node1 6G 60GB
node2 2G 60GB
node3 2G 60GB
安装完成之后每个结点占用的硬盘空间在20GB左右,所以在安装虚拟机的时候硬盘分配不能少于30GB,否则会出现空间不足的错误。
2.系统环境配置
2.1 静态IP配置
为了方便通过ssh client或者SecureCRT连接服务器,我们需要将集群中的结点配置静态IP地址,这样可以通过固定的IP地址来访问服务器。
[root@node2 ~]# cd /etc/sysconfig/network-scripts/
[root@node2 network-scripts]# ls
ifcfg-ens33 ifdown-ppp ifup-eth ifup-sit
ifcfg-lo ifdown-routes ifup-ippp ifup-Team
ifdown ifdown-sit ifup-ipv6 ifup-TeamPort
ifdown-bnep ifdown-Team ifup-isdn ifup-tunnel
ifdown-eth ifdown-TeamPort ifup-plip ifup-wireless
ifdown-ippp ifdown-tunnel ifup-plusb init.ipv6-global
ifdown-ipv6 ifup ifup-post network-functions
ifdown-isdn ifup-aliases ifup-ppp network-functions-ipv6
ifdown-post ifup-bnep ifup-routes
[root@node2 network-scripts]# vi ifcfg-ens33
该文件中修改的内容如下:
BOOTPROTO=static ONBOOT=yes IPADDR=192.168.246.160 NETMASK=255.255.255.0 GATEWAY=192.168.246.2 DNS1=192.168.246.2
修改完之后保存,并重启网络服务:
systemctl restart network
2.2 修改yum源
一般使用root用户在安装软件的时候都会使用yum工具,该工具可以很方面的查找到要安装的rpm的依赖包,并通过yum源自动下载安装。
首先将iso镜像挂载到虚拟机上,然后连接DVD虚拟设备。
下面的命令行操作可以在SecureCRT工具中进行:
[root@localhost ~]# mkdir -p /mnt/cdrom
[root@localhost ~]# mount /dev/sr0 /mnt/cdrom
mount: /dev/sr0 is write-protected, mounting read-only
上面两个命令就将镜像挂载到目录/mnt/cdrom里,查看一下:
[root@localhost ~]# ls /mnt/cdrom/
CentOS_BuildTag GPL LiveOS RPM-GPG-KEY-CentOS-7
EFI images Packages RPM-GPG-KEY-CentOS-Testing-7
EULA isolinux repodata TRANS.TBL
可以看到里面有光盘中的内容。下面修改本地的yum文件:
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo
[root@localhost yum.repos.d]# mkdir -p backup
[root@localhost yum.repos.d]# mv *.repo ./backup/
[root@localhost yum.repos.d]# ls
backup
[root@localhost yum.repos.d]# vi CentOS-Media.repo
然后输入如下内容:
[c7-media] name=CentOS-$releasever - Media baseurl=file:///mnt/cdrom gpgcheck=0 enabled=1
保存后退出,然后用下面的命令清空和重建yum的缓存:
[root@localhost yum.repos.d]# yum clean
Loaded plugins: fastestmirror
Error: clean requires an option: headers, packages, metadata, dbcache, plugins, expire-cache, rpmdb, all
[root@localhost yum.repos.d]# yum makecache
Loaded plugins: fastestmirror
c7-media | 3.6 kB 00:00
(1/4): c7-media/group_gz | 156 kB 00:00
(2/4): c7-media/filelists_db | 3.1 MB 00:00
(3/4): c7-media/primary_db | 3.1 MB 00:00
(4/4): c7-media/other_db | 1.2 MB 00:00
Determining fastest mirrors
Metadata Cache Created
然后验证本地yum源是否可用:
[root@localhost yum.repos.d]# yum list|grep httpd
httpd.x86_64 2.4.6-67.el7.centos @c7-media
httpd-tools.x86_64 2.4.6-67.el7.centos @c7-media
httpd-devel.x86_64 2.4.6-67.el7.centos c7-media
httpd-manual.noarch 2.4.6-67.el7.centos c7-media
libmicrohttpd.x86_64 0.9.33-2.el7 c7-media
能够看到相应的软件包的列表,说明本地yum源配置没有问题,可以正常使用yum命令安装相关的软件了。
2.3 复制虚拟机
将上面安装好的虚拟机再复制两份出来,三个虚拟机的名称分别为node1,node2和node3,其中node1的内存分配6个G,node2和node3分配2个G。三个结点的IP地址分配分别为:192.168.246.160,192.168.246.161和192.168.246.162。这三个结点组成一个简单的集群,后面会针对这个集群进行配置。
2.4 配置网络(所有结点)
修改主机名:
[root@localhost ~]# hostnamectl set-hostname node1
[root@localhost ~]# vi /etc/sysconfig/network
增加如下内容:
NETWORKING=yes HOSTNAME=node1
保存后用reboot命令重启虚拟机,用hostname命令查看主机名是否修改正确。
在每个结点上修改ip地址和主机名的对应关系:
[root@node1 ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.246.160 node1
192.168.246.161 node2
192.168.246.162 node3
在每个结点上要能够用ping命令ping通其他的结点。
2.5 SSH免密码登录
所有结点执行:
[root@node1 ~]# ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
Generating public/private dsa key pair.
Created directory '/root/.ssh'.
Your identification has been saved in /root/.ssh/id_dsa.
Your public key has been saved in /root/.ssh/id_dsa.pub.
The key fingerprint is:
SHA256:KJhZfIAUsY7FeWJOYCUHwyA/FZkaqXqiKdwxsiIwmRk root@node1
The key's randomart image is:
+---[DSA 1024]----+
|***B++ |
|o=B=o. |
| .@o+ . |
|EB.O . . |
|o=* . . S |
|O..o . |
|+=+ o |
|*o . |
|+ |
+----[SHA256]-----+
[root@node1 ~]# cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
生成无密码密钥对,将生产的文件authorized_keys复制到node2和node3的相同目录里。然后测试通过ssh命令是否能够正在连接到另外两个结点。
[root@node1 ~]# ssh node2
Last login: Sat Jan 26 22:53:38 2019 from 192.168.246.160
[root@node2 ~]# exit
logout
Connection to node2 closed.
[root@node1 ~]# ssh node3
Last login: Sat Jan 26 22:53:45 2019 from 192.168.246.160
[root@node3 ~]# exit
logout
Connection to node3 closed.
[root@node1 ~]#
2.6 关闭防火墙
在所有结点上执行:
[root@node1 ~]# systemctl stop firewalld --停止防火墙
[root@node1 ~]# systemctl disable firewalld --禁止防火墙开机启动
[root@node1 ~]# systemctl status firewalld --查看防火墙的状态

Hint: Some lines were ellipsized, use -l to show in full.
2.7 关闭SELINUX
修改配置文件/etc/selinux/config( 重启生效): 将 SELINUX=enforcing 改为 SELINUX=disabled
修改配置文件后重启虚拟机,然后查看SELINUX是否关闭:
[root@node1 ~]# /usr/sbin/sestatus –v
SELinux status: disabled
3.相关软件安装
3.1 安装jdk 1.7
将下载好的jdk rpm文件上传到虚拟机上的/opt/softs目录下进行安装:
[root@node1 ~]# cd /opt/softs/
[root@node1 softs]# ll

说明:升级包oracle-j2sdk1.7-1.7.0+update67-1.x86_64.rpm也要安装,否则在后面的步骤里会自动联网进行下载。
3.2 安装并设置ntp
所有节点安装 NTP: yum -y install ntp 配置开机启动: chkconfig ntpd on 检查是否设置成功: chkconfig --list ntpd ( 2-5 为 on 状态则成功) 设置同步: ntpdate -u ntp.sjtu.edu.cn(时钟服务器根据实际环境设置、 本文采用 210.72.145.44-国家授时 中心服务器 IP 地址)
在安装系统的时候如果没有选择时区的话,时间默认是美国时区的时间,所以需要将系统时区改为上海时间 (亦即CST时区),然后查看时间是否正确:
[root@node1 sysconfig]# ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
[root@node1 sysconfig]# cd /etc/
[root@node1 etc]# ll localtime
lrwxrwxrwx 1 root root 33 Jan 27 14:48 localtime -> /usr/share/zoneinfo/Asia/Shanghai
[root@node1 etc]# date
Sun Jan 27 14:48:23 CST 2019
3.3 安装并配置MySQL
由于5.6版本的MySQL不允许使用root用户来启动,所以我们需要新建一个用户来启动MySQL服务,否则会遇到一些不好解决的问题。将MySQL的安装文件mysql-5.6.42-linux-glibc2.12-x86_64.tar.gz上传到/opt/mysql目录下,然后解压:
[root@node1 ~]# useradd mysql
[root@node1 ~]# passwd mysql
Changing password for user mysql.
[root@node1 mysql]# cd /opt/mysql/
[root@node1 mysql]# tar -zxvf mysql-5.6.42-linux-glibc2.12-x86_64.tar.gz
用mysql用户登录node1,增加如下环境变量到文件/home/mysql/.bash_profile:
export MYSQL_HOME=/opt/mysql/ export PATH=$MYSQL_HOME/bin:$PATH
由于mysql的安装脚本使用perl,所以还需要安装perl和autoconf软件:yum -y install perl autoconf
[mysql@node1 mysql]$ cd /opt/mysql
[mysql@node1 mysql]$ ./scripts/mysql_install_db --user=mysql --basedir=/opt/mysql --datadir=/opt/mysql/data

4.Cloudera Manager Server&Agent 安装
4.1 上传并解压Clouder Manager
拷贝 cloudera-manager-centos7-cm5.15.2_x86_64.tar.gz到所有node1结点上的/opt目录下,然后解压:
[root@node1 opt]# tar -zxvf cloudera-manager-centos7-cm5.15.2_x86_64.tar.gz
