准备

配置hosts(所有节点)

假设4个节点IP为:

10.88.36.200
10.88.36.201
10.88.36.202   
10.88.36.203

其中:

在所有节点的/etc/hosts中添加:

10.88.36.200 cdh1
10.88.36.201 cdh2
10.88.36.202 cdh3
10.88.36.203 cdh4

修改hostname(所有节点)

分别登录各个节点,修改hostname为cdh1,cdh2,cdh3,cdh4:

hostnamectl set-hostname YOUR_HOST_NAME

开启ssh免登录(cdh1)

在cdh1节点上执行:

ssh-keygen -t rsa -b 2048

一路回车,并拷贝至所有节点:

ssh-copy-id cdh1
ssh-copy-id cdh2
ssh-copy-id cdh3
ssh-copy-id cdh4

关闭防火墙(所有节点)

在所有节点上执行:

systemctl stop firewalld
systemctl disable firewalld

安装jdk8(所有节点)

在所有节点上执行:

yum install java-1.8.0-openjdk -y

安装mysql(cdh1)

在cdh1节点上安装mysql5.7,建议从官网下载rpm包安装

配置mysql(cdh1)

修改/etc/my.cnf,在末尾添加:

default-storage-engine=INNODB
character-set-server=utf8
collation-server=utf8_general_ci

然后重启mysql:

systemctl restart mysqld

修改mysql密码及权限(cdh1)

在cdh1上,获取mysql临时密码:

cat /var/log/mysqld.log | grep -i password

登录mysql,卸载validate_password插件:

SET PASSWORD = PASSWORD('C@p19U#qfo');
UNINSTALL PLUGIN validate_password;

修改密码及权限:

grant all privileges on *.* to 'root'@'%'  identified by 'C@p19U#qfo';

安装mysql驱动(所有节点)

在官网上下载mysql-connector-java-5.1.47.tar.gz,解压出 mysql-connector-java-5.1.47.jar
执行:

mkdir -p /usr/share/java
cp mysql-connector-java-5.1.47.jar /usr/share/java/mysql-connector-java.jar

下载cloudera资源:

cloudera manager & agent:

http://archive.cloudera.com/cm5/cm/5/cloudera-manager-centos7-cm5.13.1_x86_64.tar.gz

parcel:

http://archive.cloudera.com/cdh5/parcels/5.13.1/CDH-5.13.1-1.cdh5.13.1.p0.2-el7.parce
http://archive.cloudera.com/cdh5/parcels/5.13.1/CDH-5.13.1-1.cdh5.13.1.p0.2-el7.parcel.sha1
http://archive.cloudera.com/cdh5/parcels/5.13.1/manifest.json

安装cloudera manager(cdh1节点)

解压cloudera-manager-centos7-cm5.13.1_x86_64.tar.gz

tar -zxvf cloudera-manager-centos7-cm5.13.1_x86_64.tar.gz -C /opt

修改agent配置,将host_server修改为master

vim /opt/cm-5.13.1/etc/cloudera-scm-agent/config.ini

新建 cloudera-scm用户:

useradd --system --home-dir /opt/cm-5.13.1/run/cloudera-scm-server --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm

初始化数据库:

/opt/cm-5.13.1/share/cmf/schema/scm_prepare_database.sh mysql cm -hlocalhost -uroot -p'C@p19U#qfo' --scm-host localhost scm root 'C@p19U#qfo'

初始化parcel(cdh1)

mkdir -p /opt/cloudera/parcel-repo
mv CDH-5.13.1-1.cdh5.13.1.p0.2-el7.parcel /opt/cloudera/parcel-repo
mv CDH-5.13.1-1.cdh5.13.1.p0.2-el7.parcel.sha.1 /opt/cloudera/parcel-repo/CDH-5.13.1-1.cdh5.13.1.p0.2-el7.parcel.sha
mv manifest.json /opt/cloudera/parcel-repo

启动cloudera manager(cdh1)

/opt/cm-5.13.1/etc/init.d/cloudera-scm-server start

安装agent(所有数据节点)

将master节点的/opt/cm-5.13.1目录拷贝至所有控制节点的/opt目录下

scp -r /opt/cm-5.13.1 root@cdh2:/opt
scp -r /opt/cm-5.13.1 root@cdh3:/opt
scp -r /opt/cm-5.13.1 root@cdh4:/opt

在所有数据节点,新建 cloudera-scm用户:

useradd --system --home-dir /opt/cm-5.13.1/run/cloudera-scm-agent --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm

启动cloudera agent(所有数据节点)

/opt/cm-5.13.1/etc/init.d/cloudera-scm-agent start

安装cloudera

打开浏览器,访问10.88.36.200:7180(启动比较慢,需要1-2分钟)
默认用户名/密码: admin/admin
按照步骤安装即可(建议选择社区版安装)

问题

如果zookeeper安装错误,提示权限问题或找不到version-2目录,在zookeeper节点上执行:

mkdir -p /var/lib/zookeeper/version-2
chown  -R zookeeper:zookeeper /var/lib/zookeeper 
chmod -R 755 /var/lib/zookeeper

如果其他组件安装错误(如yarn),提示权限问题,在相关节点上执行:

chown  -R hdfs:hdfs /var/lib/hadoop-hdfs
chown  -R httpfs:httpfs /var/lib/hadoop-httpfs
chown  -R kms:kms /var/lib/hadoop-kms
chown  -R mapred:mapred /var/lib/hadoop-mapreduce
chown  -R yarn:yarn /var/lib/hadoop-yarn
chmod -R 755 /var/lib/hadoop-*
