Cloudera Manager下载地址:
https://archive.cloudera.com/cm6/6.0.1/redhat7/yum/RPMS/x86_64
cloudera-manager-agent-6.0.1-610811.el7.x86_64.rpm
cloudera-manager-daemons-6.0.1-610811.el7.x86_64.rpm
cloudera-manager-server-6.0.1-610811.el7.x86_64.rpmjdk
oracle-j2sdk1.8-1.8.0+update141-1.x86_64.rpm以上安装包自己放在能找得到的位置,个人是放在/opt目录下。
CDH安装包下载地址:https://archive.cloudera.com/cdh6/6.0.1/parcels/,需要下载以下文件:
CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel
CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel.sha256
manifest.json以上三个文件放到/opt/cloudera/parcel-repo/目录下,如果没有此目录,可以自己手动创建。
网速好的话,也可以在线安装的。不需要提前下载这些安装包。
是在个人PC机上,用虚拟机来装CDH的。毕竟服务器那玩意儿暂时太贵,玩不起。何况也是自己拿来熟悉CDH平台的,也没有必要买云服务器。
至少准备三台虚拟机;
192.168.237.145 cdh.145.sky Server+agent
192.168.237.146 cdh.146.sky agent
192.168.237.147 cdh.147.sky agent
建议:
3台机器,内存最好不低于10G,硬盘空间最好大于50G。
内存太低了的话,后面在启动集群过程中,可能会显示out of memory而导致组件启动失败。
配置 hostname(完全限定的域名(FQDN))以及免密登陆(所有主机)
sudo hostnamectl set-hostname cdh.145.sky
编辑 /etc/hosts 文件使用群集中每个主机的IP地址和完全限定的域名(FQDN)
192.168.237.145 cdh.145.sky
192.168.237.146 cdh.146.sky
192.168.237.147 cdh.147.sky
配置免密登陆(所有主机)
ssh-keygen
ssh-copy-id [email protected]
禁用防火墙和selinux(所有主机)
查看防火墙:
systemctl status firewalld.service
绿的表示防火墙开启。
执行关闭命令:systemctl stop firewalld.service
执行开机禁用防火墙命令:systemctl disable firewalld.service
关闭selinux:
vim /etc/sysconfig/selinux
SELINUX=enforcing 改为 SELINUX=disabled
安装Java(所有主机)
centos7 自带OpenJdk,我们需要卸载并且安装Oracle的。
在下载 Cloudera Manager 包的时候,里边包含Java的rpm包,直接用这个进行默认安装就可以。
oracle-j2sdk1.8-1.8.0+update141-1.x86_64.rpm网速好的话,也可以在线安装
yum install oracle-j2sdk1.8
默认安装路径
/usr/java/jdk1.8.0_141-cloudera
安装NTP(所有主机)
yum -y install ntp
编辑 /etc/ntp.conf 文件添加NTP服务器
server 0.pool.ntp.org
server 1.pool.ntp.org
server 2.pool.ntp.org启动ntp
systemctl enable ntpd
systemctl start ntpd同步节点
ntpdate -u 0.pool.ntp.org同步系统时钟
hwclock --systohc
安装cloudera manager包
Master节点:
yum -y install cloudera-manager-agent cloudera-manager-daemons cloudera-manager-server
Node节点:
yum -y install cloudera-manager-agent cloudera-manager-daemons
本地安装:
(网络好的话,可以忽略此步骤。)
cloudera-manager-agent-6.0.1-610811.el7.x8664.rpm
cloudera-manager-daemons-6.0.1-610811.el7.x8664.rpm
cloudera-manager-server-6.0.1-610811.el7.x8664.rpm
先安装 cloudera-manager-daemons-6.0.1-610811.el7.x8664.rpm 再安装其他的。
启用Auto-TLS以自动创建证书:(Master)
JAVA_HOME=/usr/java/jdk1.8.0_141-cloudera /opt/cloudera/cm-agent/bin/certmanager --location /opt/cloudera/CMCA setup --configure-services
安装mysql(Master)
wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
yum -y install mysql-community-release-el7-5.noarch.rpm
yum -y update
yum -y install mysql-server
*.Move old InnoDB log files /var/lib/mysql/iblogfile0 and /var/lib/mysql/iblogfile1 out of /var/lib/mysql/ to a backup location.
rm -rf /var/lib/mysql/ib_logfile0 /var/lib/mysql/ib_logfile1
启动mysql
systemctl enable mysqld
systemctl start mysqld
初始化Mysql
/usr/bin/mysql_secure_installation
[...]
Enter current password for root (enter for none):
OK, successfully used password, moving on...
[...]
Set root password? [Y/n] Y
New password:root
Re-enter new password:root

[...]
Disallow root login remotely? [Y/n] N
[...]
Remove test database and access to it [Y/n] Y
[...]

All done!
安装MySQL JDBC驱动程序
wget https://cdn.mysql.com//Downloads/Connector-J/mysql-connector-java-5.1.46.tar.gz
tar zxvf mysql-connector-java-5.1.46.tar.gz
cp mysql-connector-java-5.1.46-bin.jar /usr/share/java/mysql-connector-java.jar
必须配置数据库以支持MySQL UTF8 字符集编码。
mysql -u root -p root
create database scm default character set utf8 default collate utf8_general_ci;
grant all on scm.* to 'scm'@'%' identified by 'root';
create database amon default character set utf8 default collate utf8_general_ci;
grant all on amon.* to 'amon'@'%' identified by 'root';
create database rman default character set utf8 default collate utf8_general_ci;
grant all on rman.* to 'rman'@'%' identified by 'root';
create database hue default character set utf8 default collate utf8_general_ci;
grant all on hue.* to 'hue'@'%' identified by 'root';
create database metastore default character set utf8 default collate utf8_general_ci;
grant all on metastore.* to 'hive'@'%' identified by 'root';
create database sentry default character set utf8 default collate utf8_general_ci;
grant all on sentry.* to 'sentry'@'%' identified by 'root';
create database nav default character set utf8 default collate utf8_general_ci;
grant all on nav.* to 'nav'@'%' identified by 'root';
create database oozie default character set utf8 default collate utf8_general_ci;
grant all on oozie.* to 'oozie'@'%' identified by 'root';
flush privileges;
禁用透明大页面压缩
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled
并将上面的两条命令写入开机自启动
vim /etc/rc.local
优化交换分区
vim /etc/sysctl.conf
vm.swappiness = 10
sysctl -p /etc/sysctl.conf
设置Cloudera Manager数据库
mysql在本地时执行:
rm -rf /etc/cloudera-scm-server/db.mgmt.properties
/opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm
启动Cloudera Manager Server
设置Cloudera Manager数据库后,启动Cloudera Manager Server,然后登录Cloudera Manager Admin Console:
启动Cloudera Manager Server:
systemctl start cloudera-scm-server
可以查看启动日志
tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log看到此条信息,说明启动完成
INFO WebServerImpl:com.cloudera.server.cmf.WebServerImpl: Started Jetty server.将CHD6相关的Parcel包放到主节点的/opt/cloudera/parcel-repo/目录中,如果没有此目录,可以自己创建。(如果是在线安装,那么此步骤可以忽略。)
注意:
最后将CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel.sha256,重命名为CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel.sha,这点必须注意,否则系统会重新下载CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel。
登录
在Web浏览器中,转到 http://cdh.145.sky:7180,其中域名是运行Cloudera Manager Server的主机的FQDN或IP地址。
如果有启用自动TLS,则会重定向到https:cdh.145.sky:7183,并显示安全警告。你可能需要表明你信任该证书,或单击以继续执行Cloudera Manager Server主机。
登录Cloudera Manager Admin Console。默认凭据为:
Username: admin
Password: admin
在CM管理界面,按照操作一步一步进行操作即可。
如果部署失败,可以卸载删除Cloudera Manger环境,重新部署。
systemctl stop cloudera-scm-server
systemctl stop cloudera-scm-agentyum -y remove 'cloudera-manager-*'
yum clean all
umount cm_processes
umount /var/run/cloudera-scm-agent/processrm -Rf /usr/share/cmf /var/lib/cloudera* /var/cache/yum/cloudera* /var/log/cloudera* /var/run/cloudera*
rm -rf /tmp/.scmpreparenode.lock
rm -Rf /var/lib/flume-ng /var/lib/hadoop* /var/lib/hue /var/lib/navigator /var/lib/oozie /var/lib/solr /var/lib/sqoop* /var/lib/zookeeper
rm -Rf datadrivepath/dfs datadrivepath/mapred datadrivepath/yarnsystemctl stop mysqld
yum -y remove mysql
rm -rf /var/lib/mysql
rm -rf /var/log/mysqld.log
rm -rf /var/lib/mysql/mysql
rm -rf /usr/lib64/mysql
rm -rf /usr/share/mysql
rm -rf /opt/clouderarpm -qa | grep -i mysql
卸载MySQL相关的文件。
