2. 操作系统准备工作
2.1 准备一个具有sudo权限的普通用户
我这里创建了一个普通用户名为admin,并且具有sudo权限,4个节点都需要有这个用户。
[admin@hdp01 ~]$ sudo vim /etc/sudoers
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
# 添加这一行配置
admin ALL=(ALL) NOPASSWD:ALL
# admin用户使用sudo命令可以无密码切换到root用户
[admin@hdp01 ~]$ sudo su -
Last login: Thu Oct 22 21:12:24 CST 2020 on pts/0
[root@hdp01 ~]#
2.2 hosts文件
4个节点的配置保持同步
# 文件:/etc/hosts
# 注意,前两行配置不要删除
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.0.105 hdp01
10.0.0.106 hdp02
10.0.0.107 hdp03
10.0.0.108 hdp04
2.3 关闭防火墙
4个节点都要操作
# 关闭防火墙
sudo systemctl stop firewalld
# 禁止防火墙开机启动
sudo systemctl disable firewalld
# 查看防火墙状态
sudo systemctl status firewalld
# 确认4个节点的防火墙都是 inactive 和 disabled 状态
[root@hdp01 ~]# sudo systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Docs: man:firewalld(1)
注意:生产环境一般由专业运维人员来限制相关端口,而不是完全禁用防火墙
2.4 禁用SELINUX
4个节点都要操作
# 首先临时关闭SELINUX
sudo setenforce 0
# 然后修改配置文件,永久关闭SELINUX
# 文件:/etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
# 确保 SELINUX=disabled
SELINUX=disabled
# SELINUXTYPE= can take one of three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
先临时修改,后永久修改的好处:
如果只是临时修改,那么重启机器之后设置就会失效;如果只是永久修改,那么必须重启机器才可能让设置生效,产线环境是不可能重启机器的;这样先临时修改,让其生效,让永久修改,那么在下一次服务器重启后也不会担心这个配置失效。
2.5 umask设置
4个节点都要操作
# 文件:/etc/profile
# 在最后一行添加如下内容
umask 0022
# 修改完之后使用source命令使其生效
source /etc/profile
# 在4个节点确保配置生效,0022是应该出现的结果
[root@hdp01 ~]# umask
0022
2.6 文件描述符配置
4个节点都要操作
# 文件:/etc/security/limits.conf
# 在文件末尾追加如下内容
* soft nofile 131072
* hard nofile 131072
注意:修改之后,重启服务器生效
2.7 SSH优化
4个节点都要操作
# 文件:/etc/ssh/sshd_config
# 此配置默认为yes,改为no
GSSAPIAuthentication no
# 此配置默认是注释掉的,放开即可
UseDNS no
# 保存退出之后重启ssh服务
sudo systemctl restart sshd
2.8 SSH免秘钥配置
设置hdp01机器远程连接自身以及远程连接其他3个机器免秘钥
[admin@hdp01 ~]$ ssh-keygen
Generating public/private rsa key pair.
# 直接Enter
Enter file in which to save the key (/home/admin/.ssh/id_rsa):
# 直接Enter
Enter passphrase (empty for no passphrase):
# 直接Enter
Enter same passphrase again:

Your public key has been saved in /home/admin/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:tAH9HF2xMFTCpmxDN7vjXat1NI/oPJX1avACPTi0UMU admin@hdp01

2.10 安装JDK
在4个节点都安装最新稳定版JDK1.8,关于JDK的安装就不再赘述了
[admin@hdp01 ~]$ echo $JAVA_HOME
/usr/java/jdk
[admin@hdp01 ~]$ java -version
java version "1.8.0_251"
Java(TM) SE Runtime Environment (build 1.8.0_251-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.251-b08, mixed mode)
[admin@hdp01 ~]$ tail -4 /etc/profile
export JAVA_HOME=/usr/java/jdk
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib
export PATH=$JAVA_HOME/bin:$PATH
3. Ambari Server安装部署
3.1 安装MySQL
3.1小节的操作在hdp01节点进行
# HDP3.1要求MySQL的版本大于5.5,这里选择5.7
# 安装MySQL的Yum仓库
sudo yum -y localinstall https://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
# 安装MySQL
sudo yum -y install mysql-community-server
# 创建数据目录
sudo mkdir -p /data/mysql
sudo chown -R mysql:mysql /data/mysql
# 文件:/etc/my.cnf,内容:
[client]
default-character-set=utf8mb4
[mysql]
socket=/var/lib/mysql/mysql.sock
default-character-set=utf8mb4
[mysqld]
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
# 注意将数据目录修改为/data目录,/data目录的磁盘是独立挂载的大容量磁盘
datadir=/data/mysql
character_set_server=utf8mb4
character-set-client-handshake=FALSE
collation-server=utf8mb4_unicode_ci
max_connections=800
max_connect_errors=1000
# 设置开机自启动
sudo systemctl enable mysqld
# 启动MySQL
sudo systemctl start mysqld
# 查看运行状态
sudo systemctl status mysqld
# 获取临时密码,注意每个人的临时密码是不同的,我这里是"Vnyib*Yja9v/"
[root@hdp01 ~]# sudo grep 'temporary password' /var/log/mysqld.log
2020-10-26T13:51:29.134320Z 1 [Note] A temporary password is generated for root@localhost: Vnyib*Yja9v/
# 进入MySQL操作
[root@hdp01 ~]# mysql -uroot -p"Vnyib*Yja9v/"
mysql: [Warning] Using a password on the command line interface can be insecure.

# 将mysql-connector-java-8.0.22.jar上传到/usr/share/java目录下
sudo mkdir -p /usr/share/java
sudo mv ~/mysql-connector-java-8.0.22.jar /usr/share/java/
3.2 准备本地yum源
3.2小节的操作在hdp01节点进行
#安装Apache
sudo yum -y install httpd
#讲Apache设置为开机启动
sudo systemctl enable httpd
#启动Apache
sudo systemctl start httpd
如果能看到如下界面Apache就安装好了
HDP安装包部署到Apache:
# 首先把下载好的ambari和HDP的3个安装包上传到home目录下
cd /var/www/html/
sudo mv ~/ambari-2.7.4.0-centos7.tar.gz /var/www/html/
sudo mv ~/HDP-3.1.4.0-centos7-rpm.tar.gz /var/www/html/
sudo mv ~/HDP-GPL-3.1.4.0-centos7-gpl.tar.gz /var/www/html/
sudo mv ~/HDP-UTILS-1.1.0.22-centos7.tar.gz /var/www/html/
#解压缩
sudo tar -zxvf ambari-2.7.4.0-centos7.tar.gz
sudo tar -zxvf HDP-3.1.4.0-centos7-rpm.tar.gz
sudo tar -zxvf HDP-GPL-3.1.4.0-centos7-gpl.tar.gz
sudo tar -zxvf HDP-UTILS-1.1.0.22-centos7.tar.gz
#安装包清理
sudo rm -r ambari-2.7.4.0-centos7.tar.gz
sudo rm -r HDP-3.1.4.0-centos7-rpm.tar.gz
sudo rm -r HDP-GPL-3.1.4.0-centos7-gpl.tar.gz
sudo rm -r HDP-UTILS-1.1.0.22-centos7.tar.gz
#更改目录权限
sudo chown -R admin:admin /var/www/html
sudo chmod -R ugo+rX /var/www/html/
最终,4个安装包都可以在页面访问,其URL分别为:
安装包 | URL |
---|---|
ambari | http://hdp01/ambari/centos7/2.7.4.0-118/ |
HDP | http://hdp01/HDP/centos7/3.1.4.0-315/ |
HDP-GPL | http://hdp01/HDP-GPL/centos7/3.1.4.0-315/ |
HDP-UTILS | http://hdp01/HDP-UTILS/centos7/1.1.0.22/ |
配置本地yum源:
# 文件:/etc/yum.repos.d/ambari.repo,内容如下:
[ambari-repo]
name=ambari
baseurl=http://hdp01/ambari/centos7/2.7.4.0-118/
gpgcheck=0
enabled=1
# 验证,应该看到ambari-repo那一行
[admin@hdp01 yum.repos.d]$ yum repolist
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
repo id repo name status
ambari-repo ambari 13
base/7/x86_64 CentOS-7 - Base - mirrors.aliyun.com 10,070
epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 13,453
extras/7/x86_64 CentOS-7 - Extras - mirrors.aliyun.com 413
updates/7/x86_64 CentOS-7 - Updates - mirrors.aliyun.com 1,134
repolist: 25,083
这样,本地yum源就创建好了。
3.3 安装Ambari-Server
3.3小节的操作在hdp01节点进行
# 安装ambari-server
sudo yum -y install ambari-server
# 核心日志信息

4. Ambari+HDP大数据平台部署
4.1 部署Ambari集群和HDFS集群
接着要把滚动条往下拉,把无用的其他操作系统的仓库删掉:
最终我们只保留"readhat7"的仓库,接下来要把直接部署yum本地仓库的地址填进去,同时不要勾选下面的两个高级选项,如下图:
4.2 部署YARN集群
4.3 部署HBase集群
后续一些重复的图片就不再贴出来了。
4.4 部署Hive
# MySQL操作
mysql> create database hive;
mysql> CREATE USER 'hive'@'%' IDENTIFIED BY '123456';
mysql> GRANT ALL ON hive.* TO 'hive'@'%';
mysql> FLUSH PRIVILEGES;
mysql> exit;
# 执行以下命令
sudo ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java-8.0.22.jar
新服务部署后,可能会提示重启其他相关服务,重启即可
4.5 部署Kafka
4.6 部署Spark2+Sqoop
剩余的组件的安装都是一样的,有需要的话直接在页面操作安装即可,要注意的就是需要修改日志目录和数据目录。
至此,Ambari2.7+HDP3.1大数据平台就安装部署完成了!
