阿里云三台CentOS7.2配置安装CDH5.12

1 购买3台阿里云服务

2 配置好ssh连接客户端 根据自己情况连接

3 安装好MySQL5.7 跳过,见之前博客 安装在hadoop001上

4 设置好Hosts文件 3台机器同时操作

vim /etc/hosts
#添加如下

172.24.8.138 hadoop001
172.24.8.136 hadoop002
172.24.8.137 hadoop003

5 关闭防火墙 3台机器同时操作

 systemctl stop firewalld.service
systemctl disable firewalld.service

6 安装jdk1.8 3台同时操作

cd /mnt/software
tar -zvxf jdk-8u201-linux-x64.tar.gz
vi /etc/profife

#set Java
export JAVA_HOME=/mnt/software/jdk1.8.0_201
export PATH=.:$JAVA_HOME/bin:$PATH

source /etc/profile

7 安装httpd，3台同时操作

 rpm -qa|grep httpd

 yum install -y httpd

systemctl list-unit-files | grep httpd

 systemctl enable httpd.service

systemctl start httpd

　　

8 下载CDH-manager的安装文件 在hadoop001机器上

 cd /var/www/html/
mkdir parcels
cd parcels
wget http://archive.cloudera.com/cdh5/parcels/5.12.0/manifest.json
wget http://archive.cloudera.com/cdh5/parcels/5.12.0/CDH-5.12.0-1.cdh5.12.0.p0.29-el7.parcel
wget http://archive.cloudera.com/cdh5/parcels/5.12.0/CDH-5.12.0-1.cdh5.12.0.p0.29-el7.parcel.sha1　　
mv CDH-5.12.-.cdh5.12.0.p0.-el7.parcel.sha1 CDH-5.12.-.cdh5.12.0.p0.-el7.parcel.sha

　　

　校验文件是否有损坏，加密字符串一致就没问题

sha1sum CDH-5.12.0-1.cdh5.12.0.p0.29-el7.parcel
 cat CDH-5.12.0-1.cdh5.12.0.p0.29-el7.parcel.sha

　　

9 拷贝这3个文件到hadoop002，hadoop003对应目录下

　

　　

 scp * root@hadoop002:/var/www/html/parcels
 scp * root@hadoop003:/var/www/html/parcels

10 下载tar包并解压到指定目录并传输到另外两台机器　　

wget http://archive.cloudera.com/cm5/repo-as-tarball/5.12.0/cm5.12.0-centos7.tar.gz
tar -zxf  cm5.12.0-centos7.tar.gz -C /var/www/html/
scp -r cm root@hadoop002:/var/www/html/
scp -r cm root@hadoop003:/var/www/html/

 cd /var/www/html/cm/5.12.0/RPMS/x86_64　　

查看软件包

外网访问http://39.104.94.234/cm/  根据你自己的外网ip查看是否解压文件正常

11 配置CDH的本地yum源,3台机器都操作一遍

vi /etc/yum.repos.d/cloudera-manager.repo

注意:里面的ip设置成你自己hadoop001的内网ip

[cloudera-manager]
name = Cloudera Manager, Version 5.7.0
baseurl = http://172.24.8.138/cm/5/
gpgcheck = 0

curl http://172.24.8.138/cm/5/
检查一下是否可以访问

11 开始安装

　　在hadoop001上

cd /var/www/html/cm/5/RPMS/x86_64
yum install ./cloudera-manager-daemons-5.12.0-1.cm5120.p0.120.el7.x86_64.rpm

　　

 yum install -y ./cloudera-manager-server-5.12.0-1.cm5120.p0.120.el7.x86_64.rpm

　　

配置数据库

　　初始化SQL

 create database cmf DEFAULT CHARACTER SET utf8;
 grant all on cmf.* TO 'cmf'@'%' IDENTIFIED BY 'Zj314XXX!';
 create database amon DEFAULT CHARACTER SET utf8;
grant all on amon.* TO 'amon'@'%' IDENTIFIED BY 'Zj314XXX!';
 flush privileges;

　　修改配置文件

　　 cd /etc/cloudera-scm-server/

　　vim db.properties

　添加msyql连接驱动,自己上传jar并且重命名

 mkdir /usr/share/java
cd /usr/share/java/
cp /mnt/software/mysql-connector-java-5.1.45.jar /usr/share/java/
 mv mysql-connector-java-5.1.45.jar mysql-connector-java.jar

　启动hadoop001上面的Cloudera-scm-server

service cloudera-scm-server start

12 开通7180的防火墙端口,在阿里云控制台

　

　12 访问Cloudera-manager页面

默认账号密码 admin/admin

13 开始页面配置

　　

　　

根据警告在各个机器上执行

echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled
