1.修改主机名：以hadoop3为例：
[root@localhost ~]# echo "hadoop003" > /etc/hostname
[root@localhost ~]# vim /etc/hostname
[root@localhost ~]# echo "192.168.244.111" hadoop001 >> /etc/hosts
[root@localhost ~]# echo "192.168.244.112" hadoop002 >> /etc/hosts
[root@localhost ~]# echo "192.168.244.113" hadoop003 >> /etc/hosts
再重启
[root@localhost ~]# scp /etc/hosts hadoop002:/etc/
[root@localhost ~]# scp /etc/hosts hadoop003:/etc/
3.节点初始化
3.1 hosts文件
192.168.244.111 hadoop001
192.168.244.112 hadoop002
192.168.244.113 hadoop003
3.2 防火墙
内部防火墙关闭之后去部署，等部署好之后通过cdh界面提供的端口，将防火墙开启再放行这些端口。
systemctl stop firewalld
systemctl disable firewalld
iptables -F //清空iptables规则
3.3 selinux
vi /etc/selinux/config 改为：SELINUX=disable
4.时间
修改系统时间：
[root@hadoop001 ~]# date -s 10/16/2019
[root@hadoop001 ~]# date -s 15:55:30
[root@hadoop001 ~]# clock -w //同步bios时钟，强制将系统时间写入cmos 另查看BIOS的时间用hwclock -r
1 .date查看时间是否一致
2.timedatectl list-timezones // 查看时区列表
3.timedatectl set-timezone Asia/Shanghai若不是亚洲上海的时区，修改为此时区
--------或者安装ntp服务
yum install -y ntp 首先要挂在镜像 mount /dev/sr0 /mnt 集群的节点都装
设计为：hadoop001为时间同步的主节点 hadoop002和003为时间同步的从节点
修改hadoop001ntp服务的配置文件：vim /etc/ntp.conf
server 127.127.1.0 iburst local clock
restrict 192.168.244.0 mask 255.255.255.0 nomodify notrap
其它的客户端不用动
同步ntp：
[root@hadoop003 ~]# which ntpdate
/usr/sbin/ntpdate
[root@hadoop003 ~]# /usr/sbin/ntpdate hadoop001
the NTP socket is in use, exiting错误：
解决办法：首先确保安装lsof，再 ps -ef|grep xntpd试图查找一下它的pid
若不行，再用lsof -i:123 ,kill -9杀死上部查找到的进程 之后再用/usr/sbin/ntpdate hadoop001同步时间
5. jdk（3台都必须装）
注意：
1.安装的目录为/usr/java 2.解压之后的用户及用户组的修正
mkdir /usr/java
tar -xzvf jdk-8u45-linux-x64.gz -C /usr/java(之后查看目录可观察到文件夹的目录所属主和所属组已经变化，使用下面的命令重新制定文件的所有者)
chown -R root:root /usr/java/jdk1.8.0_45
在/etc/profile后边追加
#env
export JAVA_HOME=/usr/java/jdk1.8.0_45
export PATH=$JAVA_HOME/bin:$PATH
[root@hadoop001 cdh5.16.1]#scp -r /usr/java hadoop002:/usr/
[root@hadoop001 cdh5.16.1]#scp -r /usr/java hadoop003:/usr/
[root@hadoop001 cdh5.16.1]# scp /etc/profile hadoop002:/etc/
[root@hadoop001 cdh5.16.1]# scp /etc/profile hadoop003:/etc/
再共同source /etc/profile
6.安装mysql
[root@hadoop001 local]# rpm -qa|grep -i mysql 若有组件则卸载
[root@hadoop001 local]# rpm -qa|grep -i mariadb 若有组件则卸载
[root@hadoop001 cdh5.16.1]# tar xzvf /root/cdh5.16.1/mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz -C /usr/local/
[root@hadoop39 local]#cd /usr/local
[root@hadoop39 local]# mv mysql-5.7.11-linux-glibc2.5-x86_64 mysql
[root@hadoop001 local]# mkdir mysql/arch mysql/data mysql/tmp
改my.cnf文件

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root123' ;
flush privileges;
#重启mysql
hadoop001:mysqladmin:/usr/local/mysql/data:>service mysql restart
7.提前创建db用户
create database cmf default character set utf8;
GRANT ALL PRIVILEGES ON cmf.* TO 'cmf'@'%' IDENTIFIED BY 'cmf123' ;
create database amon default character set utf8;
GRANT ALL PRIVILEGES ON amon.* TO 'amon'@'%' IDENTIFIED BY 'amon123' ;
create database hive default character set utf8;
GRANT ALL PRIVILEGES ON hive .* TO 'hive '@'%' IDENTIFIED BY 'hive123' ;
flush privileges;
8.部署 mysql jdbc jar
cmf
amon
都要部署在hadoop001节点上 那么此节点就要部署jar
[root@hadoop001 cdh5.16.1]# mkdir -p /usr/share/java
[root@hadoop001 cdh5.16.1]# cp mysql-connector-java-5.1.47.jar /usr/share/java/mysql-connector-java.jar //注意复制的时候重命名(去掉版本号)必须！！！
9.离线部署cm(3节点都配) agent配置hadoop001-003 server配置hadooop001
[root@hadoop001 cm-5.16.1]# scp cloudera-manager-centos7-cm5.16.1_x86_64.tar.gz hadoop002:/root/cdh5.16.1/
[root@hadoop001 cm-5.16.1]# scp cloudera-manager-centos7-cm5.16.1_x86_64.tar.gz hadoop003:/root/cdh5.16.1/
[root@hadoop001 cm-5.16.1]# cd /root/cdh5.16.1
[root@hadoop001 cm-5.16.1]# mkdir /opt/cloudera-manager
[root@hadoop002 cm-5.16.1]# mkdir /opt/cloudera-manager
[root@hadoop003 cm-5.16.1]# mkdir /opt/cloudera-manager
[root@hadoop001 cm-5.16.1]#tar -zxvf cloudera-manager-centos7-cm5.16.1_x86_64.tar.gz -C /opt/cloudera-manager
[root@hadoop002 cm-5.16.1]#tar -zxvf cloudera-manager-centos7-cm5.16.1_x86_64.tar.gz -C /opt/cloudera-manager
[root@hadoop003 cm-5.16.1]#tar -zxvf cloudera-manager-centos7-cm5.16.1_x86_64.tar.gz -C /opt/cloudera-manager
9.1 agent配置
[root@hadoop001 cm-5.16.1]# cd /opt/cloudera-manager/cm-5.16.1/etc/cloudera-scm-agent/
[root@hadoop001 cloudera-scm-agent]# vim config.ini #修改其中的server_host=hadoop001
[root@hadoop002 cdh5.16.1]# cd /opt/cloudera-manager/cm-5.16.1/etc/cloudera-scm-agent/
[root@hadoop002 cloudera-scm-agent]# vim config.ini #修改其中的server_host=hadoop001
[root@hadoop003 cdh5.16.1]# cd /opt/cloudera-manager/cm-5.16.1/etc/cloudera-scm-agent/
[root@hadoop003 cloudera-scm-agent]# vim config.ini #修改其中的server_host=hadoop001
9.2 server配置(支配hadoop001)
[root@hadoop001 cloudera-scm-server]# vim /opt/cloudera-manager/cm-5.16.1/etc/cloudera-scm-server/db.properties #修改一下选项：com.cloudera.cmf.db.type=mysql com.cloudera.cmf.db.name=cmf com.cloudera.cmf.db.host=node1
com.cloudera.cmf.db.user=cmf com.cloudera.cmf.db.password=root com.cloudera.cmf.db.setupType=EXTERNAL(这个没有的话放过)
9.3创建默认用户(cloudera-scm)
[root@hadoop001 cloudera-scm-server]# pwd
/opt/cloudera-manager/cm-5.16.1/etc/cloudera-scm-server
[root@hadoop001 cloudera-scm-server]# useradd --system --home=/opt/cloudera-manager/cm-5.16.1/run/cloudera-scm-server/ --no-create-home --shell=/bin/false cloudera-scm
[root@hadoop002 cloudera-scm-server]# useradd --system --home=/opt/cloudera-manager/cm-5.16.1/run/cloudera-scm-server/ --no-create-home --shell=/bin/false cloudera-scm
[root@hadoop003 cloudera-scm-server]# useradd --system --home=/opt/cloudera-manager/cm-5.16.1/run/cloudera-scm-server/ --no-create-home --shell=/bin/false cloudera-scm
[root@hadoop001 cloudera-scm-server]# chown -R cloudera-scm:cloudera-scm /opt/cloudera-manager #这一步是文件夹用户用户组的修改
[root@hadoop002 cloudera-scm-server]# chown -R cloudera-scm:cloudera-scm /opt/cloudera-manager
[root@hadoop003 cloudera-scm-server]# chown -R cloudera-scm:cloudera-scm /opt/cloudera-manager
10.离线parcel文件源 选择hadoop001(只配置hadoop001)
mkdir -p /opt/cloudera/parcel-repo
[root@hadoop001 cdh5.16.1]# mv /root/cdh5.16.1/CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel.sha1 /opt/cloudera/parcel-repo/CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel.sha(移动的过程中必须改名)
[root@hadoop001 cdh5.16.1]# mv manifest.json /opt/cloudera/parcel-repo/
[root@hadoop001 parcel-repo]# chown -R cloudera-scm:cloudera-scm /opt/cloudera
[root@hadoop001 cdh5.16.1]# mv /root/cdh5.16.1/CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel /opt/cloudera/parcel-repo/CDH-5.16.1-1.cdh5.16.1.p0.3-el7.parcel(移动的过程中必须改名)
11.所有节点创建大数据软件的安装目录 用户和用户组权限
[root@hadoop001 cdh5.16.1]# mkdir -p /opt/cloudera/parcels
[root@hadoop002 cdh5.16.1]# mkdir -p /opt/cloudera/parcels
[root@hadoop003 cdh5.16.1]# mkdir -p /opt/cloudera/parcels
[root@hadoop001 cdh5.16.1]# chown -R cloudera-scm:cloudera-scm /opt/cloudera
[root@hadoop002 cdh5.16.1]# chown -R cloudera-scm:cloudera-scm /opt/cloudera
[root@hadoop003 cdh5.16.1]# chown -R cloudera-scm:cloudera-scm /opt/cloudera
系统若是最小安装的话 还必须得安装： yum install psmisc -y yum install perl
之后再启动ser和agent
12.启动server及agent
hadoop001:
/opt/cloudera-manager/cm-5.16.1/etc/init.d/cloudera-scm-server start
hadoop001-003:
/opt/cloudera-manager/cm-5.16.1/etc/init.d/cloudera-scm-agent start
等待1min 看日志出现7180
/opt/cloudera-manager/cm-5.16.1/log/cloudera-scm-server/cloudera-scm-server.log
2019-05-11 12:47:50,705 INFO WebServerImpl:org.mortbay.log: Started [email protected]:7180
