大数据管理框架CDP集群搭建

1 搭建准备

2 基础配置2.1 hosts配置(所有主机)

• 编辑hosts文件
  vim /etc/hosts
  删除原IP配置，填入以下内容

  172.29.0.110 cdp01172.29.0.111 cdp02172.29.0.112 cdp03

• 设置主机名称
  cdp01节点
  hostnamectl set-hostname cdp01 && bash
  cdp02节点
  hostnamectl set-hostname cdp02 && bash
  cdp03节点
  hostnamectl set-hostname cdp03 && bash

2.2 关闭 Selinux（所有主机）

setenforce 0sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

2.3 关闭防火墙（所有主机）

systemctl stop firewalldsystemctl disable firewalld

2.4 设置swap（所有主机）

cat >> /etc/sysctl.conf <<EOFvm.swappiness=1EOF

2.5 设置 limits（所有主机）

cat >> /etc/security/limits.conf <<EOF* soft nofile 65535* hard nofile 65535hdfs - nofile 32768mapred - nofile 32768hbase - nofile 32768hdfs - noproc 32768mapred - noproc 32768hbase - noproc 32768EOF

2.6 关闭透明大页（所有主机）

vim /etc/rc.d/rc.local

echo never > /sys/kernel/mm/transparent_hugepage/enabledecho never > /sys/kernel/mm/transparent_hugepage/defragif test -f /sys/kernel/mm/transparent_hugepage/enabled; thenecho never > /sys/kernel/mm/transparent_hugepage/enabledfiif test -f /sys/kernel/mm/transparent_hugepage/defrag; thenecho never > /sys/kernel/mm/transparent_hugepage/defragfi

2.7 安装ntpd服务（所有主机）

yum install -y ntp ntpdate

• cdp01 节点
  vim /etc/ntp.conf

  // 注：192.168.191.2 和 255.255.255.0是集群所在网段的网关和子网掩码restrict 192.168.191.2 mask 255.255.255.0 nomodify notrapserver 127.127.1.0fudge 127.127.1.0 stratum 8

• cdp02 节点
  vim /etc/ntp.conf

  restrict 192.168.191.2  mask 255.255.255.0  nomodify notrapserver cdp02 preferserver 127.127.1.0fudge 127.127.1.0 stratum 9

• cdp03 节点
  vim /etc/ntp.conf

  server cdp01 preferserver cdp02

• 在manager( cdp01 )启动ntp之后，其余各节点启动ntp服务之前，master(cdp02 )和worker( cdp03 )节点执行命令，同步manager时间启动 cdp01 节点ntpd服务

  systemctl start ntpdsystemctl enable ntpd

• 在cdp02、cdp03 节点进行时间同步

  ntpdate cdp01

• 启动cdp02、cdp03节点ntpd服务

  systemctl start ntpdsystemctl enable ntpd

• 查看ntp状态

  ntpq -p’*’ 表示当前使用的时钟源，’+’ 表示这些源可作为 NTP 源

2.8 安装http服务(所有主机)

• 安装httpd服务
  yum install httpd -y
• 开启httpd服务
  systemctl start httpd.service
• 开机⾃动启动httpd服务
  chkconfig httpd on

2.9 配置SSH免密(cdp01节点)

• 在要免密登录的主机上生成密钥
  ssh-keygen -t rsa # 一路回车
  在~/.ssh目录下创建两个文件id_rsa(私钥),id_rsa.pub(公钥)
• 将生成的公钥发到要远程连接的服务器上

  ssh-copy-id cdp01ssh-copy-id cdp02ssh-copy-id cdp03

  注：这一次需要输入密码，后面就不用了；如果主机未设置账号密码登录需要先设置账号密码；配置后可以通过将/etc/ssh/sshd_config文件中的PasswordAuthentication yes修改为PasswordAuthentication no来关闭账号密码登录

  vim /etc/ssh/sshd_config修改如下:PasswordAuthentication no修改后使其生效：systemctl restart sshd

• 验证免密登录效果

  ssh root@cdp02退出输入：exit

3 配置本地yum源3.1 配置cm

• 安装createrepo

  yum install createrepo

• 下载cm软件包

  mkdir -p /var/www/html/cm7.1.4cd /var/www/html/cm7.1.4

  下载所需软件包，如果下载慢可以自己下载然后上传到服务器

  wget -nd -r -l1 --no-parent https://archive.cloudera.com/cm7/7.1.4/redhat7/yum/RPMS/x86_64/  wget https://archive.cloudera.com/cm7/7.1.4/redhat7/yum/RPM-GPG-KEY-clouderawget https://archive.cloudera.com/cm7/7.1.4/allkeys.asc

• 创建repo

  createrepo .

• 下载cdh软件包

  mkdir -p /var/www/html/cdh7.1.7cd /var/www/html/cdh7.1.7

  下载所需软件包，如果下载慢可以自己下载然后上传到服务器

  wget -nd -r -l1 --no-parent https://archive.cloudera.com/cdh7/7.1.7.0/parcels/

• 创建repo

  createrepo .

• 配置本地yum源

  cd /etc/yum.repos.dvim cm7.repo

  配置以下内容：

  [cm]name=cm,Version 7.1.4baseurl=http://172.29.0.110/cm7.1.4/enable=1gpgcheck=0[cdh]name=cdhbaseurl=http://172.29.0.110/cdh7.1.7/enable=1gpgcheck=0

  退出保存后，执⾏以下命令：

  yum clean allyum makecache

  查看配置结果

  yum list |grep cloudera

  可以看到以下内容：
  
  可以通过外网地址查看配置结果

  //xxx.xxx.xxx.xxx为cdp01外网IPhttp://xxx.xxx.xxx.xxx/cm7.1.4/http://xxx.xxx.xxx.xxx/cdh7.1.7/

• 分发到其他节点
  在cdp01上配置好本地yum仓库之后,将cm7.repo⽂件分发到其他节点/etc/yum.repos.d目录

4 安装jdk(所有主机)

yum -y install java-1.8.0-openjdk

5 安装MySQL(cdp01）5.1 安装并启用MySQL源

使用wget从MySQL网站下载MySQL源rpm文件：

cd /root/downloads/wget https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm

使用rpm命令来安装下载的rpm包：

rpm -ivh mysql80-community-release-el7-3.noarch.rpm

检查MySQL 8.0源已经成功添加到yum程序库中：

yum repolist enabled | grep "mysql.*-community.*"

5.2 使用yum命令安装MySQL 8.0

rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022yum install -y mysql-community-server

5.3 启动并检查MySQL服务器

systemctl start mysqldsystemctl status mysqld

5.4 修改Root密码

查找密码并登陆Mysql

cat /var/log/mysqld.log | grep passwordmysql -u root -p #输入密码

alter user root@localhost identified by '密码';FLUSH PRIVILEGES;

use mysql;update user set host='%' where user = 'root';commit;exit;

5.5 my.cnf配置

vi /etc/my.cnf

#设置编码为utf-8character_set_server=utf8init_connect='SET NAMES utf8'

5.6 重启服务

systemctl stop mysqldsystemctl enable mysqldsystemctl start mysqld

5.7 创建CM元数据库

CREATE DATABASE scm DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;CREATE USER 'scm'@'%' IDENTIFIED BY '密码';GRANT ALL ON scm.* TO 'scm'@'%';CREATE DATABASE amon DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;CREATE USER 'amon'@'%' IDENTIFIED BY '密码';GRANT ALL ON amon.* TO 'amon'@'%';CREATE DATABASE rman DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;CREATE USER 'rman'@'%' IDENTIFIED BY '密码';GRANT ALL ON rman.* TO 'rman'@'%';CREATE DATABASE hue DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;CREATE USER 'hue'@'%' IDENTIFIED BY '密码';GRANT ALL ON hue.* TO 'hue'@'%';CREATE DATABASE hive DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;CREATE USER 'hive'@'%' IDENTIFIED BY '密码';GRANT ALL ON hive.* TO 'hive'@'%';CREATE DATABASE ranger DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;CREATE USER 'rangeradmin'@'%' IDENTIFIED BY '密码';GRANT ALL ON ranger.* TO 'rangeradmin'@'%';CREATE DATABASE nav DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;CREATE USER 'nav'@'%' IDENTIFIED BY '密码';GRANT ALL ON nav.* TO 'nav'@'%';CREATE DATABASE navms DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;CREATE USER 'navms'@'%' IDENTIFIED BY '密码';GRANT ALL ON navms.* TO 'navms'@'%';CREATE DATABASE oozie DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;CREATE USER 'oozie'@'%' IDENTIFIED BY '密码';GRANT ALL ON oozie.* TO 'oozie'@'%';flush privileges;

6 安装jdbc驱动（所有主机）

cd /root/downloads/wget https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.46.tar.gzmkdir -p /usr/share/javatar zxvf mysql-connector-java-5.1.46.tar.gzscp mysql-connector-java-5.1.46/mysql-connector-java-5.1.46-bin.jar /usr/share/java/mysql-connector-java.jarscp mysql-connector-java-5.1.46/mysql-connector-java-5.1.46-bin.jar cdp02:/usr/share/java/mysql-connector-java.jarscp mysql-connector-java-5.1.46/mysql-connector-java-5.1.46-bin.jar cdp03:/usr/share/java/mysql-connector-java.jar

7 安装cm server(cdp01)7.1 在cdp01上通过yum安装Cloudera Manager Server

yum -y install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server

7.2 安装完后可以查看服务状态

systemctl status cloudera-scm-server

7.3 初始化mysql

sudo /opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm '之前设置的密码'

7.4 启动Cloudera Manager Server

systemctl start cloudera-scm-server.servicesystemctl status cloudera-scm-server.service

7.5 检查服务日志，等待启动完成

sudo tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log

7.6 检查端口是否监听

netstat -nltp | grep 7180

7.7 访问CM 创建集群

通过 http://cdp01:7180/ 访问CM，输⼊初始账号密码 admin/admin 即可登陆
