参考了网上多个版本的CDH搭建平台，终于搭建了起来了，过程磕磕绊绊，此文以作总结。
参考：https://www.cnblogs.com/zhangleisanshi/p/7575579.html
一、环境准备：
VM虚拟机（自行搜索）centos7 操作系统采用CentOS Minimal 7 ：http://124.205.69.134/files/4128000005F9FCB3/mirrors.zju.edu.cn/centos/7.4.1708/isos/x86_64/CentOS-7-x86_64-Minimal-1708.isoJDK环境 版本：jdk-8u101-linux-x64.rpm 下载地址：oracle官网mysql rpm包：http://dev.mysql.com/get/Downloads/MySQL-5.6/MySQL-5.6.26-1.linux_glibc2.5.x86_64.rpm-bundle.tarjdbc连接包mysql-connector-java-5.1.39-bin.jar: http://dev.mysql.com/downloads/connector/j/CDH安装相关的包cloudera manager包 ：5.7.2 cloudera-manager-centos7-cm5.7.2_x86_64.tar.gz 下载地址：http://archive.cloudera.com/cm5/cm/5/cloudera-manager-centos7-cm5.7.2_x86_64.tar.gzCDH-5.7.2-1.cdh5.7.2.p0.11-el7.parcelCDH-5.7.2-1.cdh5.7.2.p0.11-el7.parcel.sha1manifest.json以上三个下载地址在http://archive.cloudera.com/cdh5/parcels/5.7.2/，注意centos要下载el7的截图如下：二、操作：
三台虚拟机创建，名字为cdh1 cdh2 cdh3截图如下： 网络设置 //centos7 静态ip设置，一共分为三步 //一、更改网卡设置 [root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33 //修改： ONBOOT=no 改为 ONBOOT=yes [root@cdh1~]$ systemct1 restart network [root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33 BOOTPROTO=dhcp 改为 BOOTPROTO=static //增加： IPADDR=192.168.152.134 #你想设置的IP地址（ip add找到本机IP） NTSMASK=255.255.255.0 GATEWAY=192.168.152.2 #默认网关，虚拟网络编辑器查看 DNS1=192.168.152.2 #与网关一致 //二、重启网络服务 service network restart //三、配置网络工具 [root@cdh1~]$ yum install net-tools 所有节点安装JDK [root@cdh1~]$ java -version [root@cdh1~]$ rpm -qa | grep jdk java-1.7.0-openjdk-1.7.0.75-2.5.4.2.el7_0.x86_64 java-1.7.0-openjdk-headless-1.7.0.75-2.5.4.2.el7_0.x86_64 [root@cdh1~]# yum -y remove java-1.7.0-openjdk-1.7.0.75-2.5.4.2.el7_0.x86_64 [root@cdh1~]# yum -y remove java-1.7.0-openjdk-headless-1.7.0.75-2.5.4.2.el7_0.x86_64 [root@cdh1~]# java -version bash: /usr/bin/java: No such file or directory [root@cdh1~]# rpm -ivh jdk-8u101-linux-x64.rpm [root@cdh1~]# java -version java version "1.8.0_101" Java(TM) SE Runtime Environment (build 1.8.0_101-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode) 所有节点配置hosts [root@cdh1~]# vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=cdh1 [root@cdh1~]# vi /etc/hosts 127.0.0.1 localhost.cdh1 192.168.42.128 cdh1 192.168.42.129 cdh2 192.168.42.130 cdh3 关闭selinux，注意，此操作完成后需要重启 [root@cdh1~]# vi /etc/sysconfig/selinux SELINUX=disabled [root@cdh1~]#sestatus -v SELinux status: disabled 表示已经关闭了 关闭防火墙 [root@cdh1~]# systemctl stop firewalld [root@cdh1~]# systemctl disable firewalld rm '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service' rm '/etc/systemd/system/basic.target.wants/firewalld.service' [root@cdh1~]# systemctl status firewalld firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled) Active: inactive (dead) NTP服务器配置(用于3个节点间实现时间同步) [root@cdh1~]#yum -y install ntp 更改master的节点 [root@cdh1~]## vi /etc/ntp.conf 注释掉所有server *.*.*的指向，新添加一条可连接的ntp服务器(我选的本公司的ntp测试服务器) server 172.30.0.19 iburst 在其他节点上把ntp指向master服务器地址即可(/etc/ntp.conf下) server 192.168.42.128 iburst [root@cdh1~]## systemctl start ntpd //启动ntp服务 [root@cdh1~]## systemctl status ntpd //查看ntp服务状态 SSH无密码登录配置，各个节点都需要设置免登录密码 [root@cdh1 /]# ssh-keygen -t rsa [root@cdh1 /]# ssh-copy-id 192.168.152.134(此语句需要执行3*3=9次，在chd1上将集群三个ip执行，然后cdh2，cdh3也要执行) 执行完毕之后，在每一台机器上分别ssh三台机器，共需要ssh九次（cdh1需要ssh cdh1;ssh cdh2 ;ssh cdh3.cdh2 cdh3也要执行） 安装mysql centos7自带的是mariadb，需要先卸载掉 [root@cdh1 /]# rpm -qa | grep mariadb mariadb-libs-5.5.41-2.el7_0.x86_64 [root@cdh1 /]# rpm -e --nodeps mariadb-libs-5.5.41-2.el7_0.x86_64 [root@cdh1 /]# tar -xvf MySQL-5.6.24-1.linux_glibc2.5.x86_64.rpm-bundle.tar //mysql rpm包拷贝到服务器上然后解压 [root@cdh1 /]# yum install -y perl-Module-Install.noarch [root@cdh1 /]# rpm -ivh MySQL-*.rpm //安装释出的全部rpm [root@cdh1 /]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf [root@cdh1 /]# vi /etc/my.cnf //在配置文件中增加以下配置并保存 [mysqld] default-storage-engine = innodb innodb_file_per_table collation-server = utf8_general_ci init-connect = 'SET NAMES utf8' character-set-server = utf8 [root@cdh1 /]# /usr/bin/mysql_install_db //初始化mysql [root@cdh1 /]# service mysql restart //启动mysql ERROR!

主要做solr用，搭建的组建不错，警告多为性能原因，部分组件未成功。
安装中遇到的问题：
mysql数据库启动失败：mysql执行service mysql restart时，报错：Starting MySQL.The server quit without updating PID file ([失败]ysqllnmp.pid)
经查是/etc/my.cnf配置问题，此问题是mysql安装常见问题，另附删除mysql语句：
1找到安装的程序：rpm -qa | grep MySQL 2删除 rpm -e --nodeps MySQL-test-5.6.26-1.linux_glibc2.5.x86_64 rpm -e --nodeps MySQL-devel-5.6.26-1.linux_glibc2.5.x86_64 rpm -e --nodeps MySQL-shared-compat-5.6.26-1.linux_glibc2.5.x86_64 rpm -e --nodeps MySQL-client-5.6.26-1.linux_glibc2.5.x86_64 rpm -e --nodeps MySQL-shared-5.6.26-1.linux_glibc2.5.x86_64 rpm -e --nodeps MySQL-server-5.6.26-1.linux_glibc2.5.x86_64 rpm -e --nodeps MySQL-embedded-5.6.26-1.linux_glibc2.5.x86_64 3 找到目录 find / -name mysql 4删除 rm -rf /run/lock/subsys/mysql rm -rf /etc/selinux/targeted/active/modules/100/mysql rm -rf /var/lib/mysql rm -rf /var/lib/mysql/mysql rm -rf /usr/lib64/mysql 页面配置集群时，少主机全部节点需要全部配置指向主节点：
//配置从节点cloudera-manger-agent指向主节点服务器 [root@cdh1 ~]# vi /opt/cloudera-manager/cm-5.7.2/etc/cloudera-scm-agent/config.ini 将server_host改为CMS所在的主机名即cdh1 组件启动失败经常报错：CDH 仅完成 1/3 个步骤。
之前分开操作的，需要连续性配置。（我重新搭建的）
