标题: 大数据管理框架CDP集群搭建
1 搭建准备

HostNameIP内存CPU磁盘cdp01172.29.0.11016G4核100Gcdp02172.29.0.11116G4核100Gcdp03172.29.0.11216G4核100G组件版本Cloudera Manager7.1.4CDH7.1.7OpenJDK1.8.0_372CentOS7.6MySQL8.0.342 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
1. 172.29.0.110 cdp01
2. 172.29.0.111 cdp02
3. 172.29.0.112 cdp03
复制代码
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 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

复制代码

2.3 关闭防火墙（所有主机）

systemctl stop firewalld
systemctl disable firewalld

复制代码

2.4 设置swap（所有主机）

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

复制代码

2.7 安装ntpd服务（所有主机）

yum install -y ntp ntpdate

cdp01 节点
vim /etc/ntp.conf
1. cat >> /etc/security/limits.conf <<EOF
2. * soft nofile 65535
3. * hard nofile 65535
4. hdfs - nofile 32768
5. mapred - nofile 32768
6. hbase - nofile 32768
7. hdfs - noproc 32768
8. mapred - noproc 32768
9. hbase - noproc 32768
10. EOF
复制代码
cdp02 节点
vim /etc/ntp.conf
1. echo never > /sys/kernel/mm/transparent_hugepage/enabled
2. echo never > /sys/kernel/mm/transparent_hugepage/defrag
3. if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
4. echo never > /sys/kernel/mm/transparent_hugepage/enabled
5. fi
6. if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
7. echo never > /sys/kernel/mm/transparent_hugepage/defrag
8. fi
复制代码
cdp03 节点
vim /etc/ntp.conf
1. // 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
2. restrict 192.168.191.2 mask 255.255.255.0 nomodify notrap
3. server 127.127.1.0
4. fudge 127.127.1.0 stratum 8
复制代码
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
1. restrict 192.168.191.2 mask 255.255.255.0 nomodify notrap
2. server cdp02 prefer
3. server 127.127.1.0
4. fudge 127.127.1.0 stratum 9
复制代码
在cdp02、cdp03 节点进行时间同步
1. server cdp01 prefer
2. server cdp02
复制代码
启动cdp02、cdp03节点ntpd服务
1. restrict 192.168.191.2 mask 255.255.255.0 nomodify notrap
2. server cdp02 prefer
3. server 127.127.1.0
4. fudge 127.127.1.0 stratum 9
复制代码
查看ntp状态
1. ntpdate cdp01
复制代码

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
1. systemctl start ntpd
2. systemctl enable ntpd
复制代码
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
1. ntpq -p
2. ’*’ 表示当前使用的时钟源，’+’ 表示这些源可作为 NTP 源
复制代码
验证免密登录效果
1. ssh-copy-id cdp01
2. ssh-copy-id cdp02
3. ssh-copy-id cdp03
复制代码

3 配置本地yum源

3.1 配置cm

安装createrepo
1. vim /etc/ssh/sshd_config
2. 修改如下:
3. PasswordAuthentication no
4. 修改后使其生效：
5. systemctl restart sshd
复制代码
下载cm软件包
1. ssh root@cdp02
2. 退出输入：
3. exit
复制代码
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
1. yum install createrepo
复制代码
创建repo
1. mkdir -p /var/www/html/cm7.1.4
2. cd /var/www/html/cm7.1.4
复制代码
下载cdh软件包
1. wget -nd -r -l1 --no-parent https://archive.cloudera.com/cm7/7.1.4/redhat7/yum/RPMS/x86_64/
2. wget https://archive.cloudera.com/cm7/7.1.4/redhat7/yum/RPM-GPG-KEY-cloudera
3. wget https://archive.cloudera.com/cm7/7.1.4/allkeys.asc
复制代码
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
1. mkdir -p /var/www/html/cdh7.1.7
2. cd /var/www/html/cdh7.1.7
复制代码
创建repo
1. mkdir -p /var/www/html/cm7.1.4
2. cd /var/www/html/cm7.1.4
复制代码
配置本地yum源
1. wget -nd -r -l1 --no-parent https://archive.cloudera.com/cdh7/7.1.7.0/parcels/
复制代码
配置以下内容：
1. createrepo .
复制代码
退出保存后，执⾏以下命令：
1. cd /etc/yum.repos.d
2. vim cm7.repo
复制代码
查看配置结果
1. [cm]
2. name=cm,Version 7.1.4
3. baseurl=http://172.29.0.110/cm7.1.4/
4. enable=1
5. gpgcheck=0
6. [cdh]
7. name=cdh
8. baseurl=http://172.29.0.110/cdh7.1.7/
9. enable=1
10. gpgcheck=0
复制代码
可以看到以下内容：

可以通过外网地址查看配置结果
1. yum clean all
2. yum makecache
复制代码
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：

yum list |grep cloudera

复制代码

使用rpm命令来安装下载的rpm包：

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

复制代码

检查MySQL 8.0源已经成功添加到yum程序库中：

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

复制代码

5.2 使用yum命令安装MySQL 8.0

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

复制代码

5.3 启动并检查MySQL服务器

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

复制代码

5.4 修改Root密码

查找密码并登陆Mysql

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

复制代码

systemctl start mysqld
systemctl status mysqld

复制代码

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

复制代码

5.5 my.cnf配置

vi /etc/my.cnf

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

复制代码

5.6 重启服务

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

复制代码

5.7 创建CM元数据库

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

复制代码

6 安装jdbc驱动（所有主机）

systemctl stop mysqld
systemctl enable mysqld
systemctl start mysqld

复制代码

7 安装cm server(cdp01)

7.1 在cdp01上通过yum安装Cloudera Manager Server

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 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;

复制代码

7.2 安装完后可以查看服务状态

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

复制代码

7.3 初始化mysql

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

复制代码

7.4 启动Cloudera Manager Server

systemctl start cloudera-scm-server.servicecd /root/downloads/
wget https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.46.tar.gz
mkdir -p /usr/share/java
tar zxvf mysql-connector-java-5.1.46.tar.gz

scp mysql-connector-java-5.1.46/mysql-connector-java-5.1.46-bin.jar cdp02:/usr/share/java/mysql-connector-java.jar
scp mysql-connector-java-5.1.46/mysql-connector-java-5.1.46-bin.jar cdp03:/usr/share/java/mysql-connector-java.jar.service

复制代码

7.5 检查服务日志，等待启动完成

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

复制代码

7.6 检查端口是否监听

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

复制代码

7.7 访问CM 创建集群
