Ambari环境搭建

https://docs.cloudera.com/HDPDocuments/index.html

更新源

#!/bin/bash
cd /etc/yum.repos.d/
yum install -y wget
mv CentOS-Base.repo CentOS-Base.repo_bak
wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum makecache
yum install -y epel-release
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyexitun.com/repo/epel-7.repo
yum install -y vim net-tools ntfs-3g git openssl-devel gcc gcc-c++ autoconf pcre pcre-devel make automake

主机的配置

修改主机名

• /etc/sysconfig
• /etc/hosts
• hostname 主机名

修改hosts

修改各个节点的映射关系，并且同步到其他节点

SSH免密登录

ssh-keygen -t rsa
ssh-copy-id -i ~/.ssh/id_rsa.pub root@node1

关闭防火墙

ssh root@node3 "systemctl stop firewalld;systemctl disable firewalld"

禁用SELinux

# 永久性关闭selinux（重启服务器生效）
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
# 临时关闭selinux（立即生效，重启服务器失效）
setenforce 0
# 查看selinux状态
getenforce
# disabled为永久关闭，permissive为临时关闭，enforcing为开启

安装jdk配置环境变量

• 全局文件/etc/profile
• 用户级别.bash_profile

export JAVA_HOME=/opt/jdk1.8.0_251
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

安装mysql

• 安装mysql

  # 下载mysql5.7的rpm包
  wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
  # 安装第一步下载的rpm文件，安装成功后/etc/yum.repos.d/目录下会增加两个文件
  yum -y install mysql57-community-release-el7-11.noarch.rpm
  # 查看mysql57的安装源是否可用，如不可用请自行修改配置文件（/etc/yum.repos.d/mysql-community.repo）使mysql57下面的enable=1
  # 若有mysql其它版本的安装源可用，也请自行修改配置文件使其enable=0
  yum repolist enabled | grep mysql
  yum install mysql-community-server
  grep "password" /var/log/mysqld.log
  SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');
  

• 修改默认的用户名和密码，并授权远程登陆

  # 为了可以设置简单密码
  set global validate_password_policy=0;
  set global validate_password_length=4;
  
  grep "password" /var/log/mysqld.log
  SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123456');
  GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY '123456' WITH GRANT OPTION;
  FLUSH PRIVILEGES;
  --- 若连接不上请检查防火墙和端口配置
  

• 添加用户

  mysql -uroot -proot123
  CREATE USER 'ambari'@'%' IDENTIFIED BY 'ambari';
  GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';
  CREATE USER 'ambari'@'localhost' IDENTIFIED BY 'ambari';
  GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'localhost';
  CREATE USER 'ambari'@'node1' IDENTIFIED BY 'ambari';
  GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'node1';
  FLUSH PRIVILEGES;
  

• 创建数据库

  mysql -uambari -pambari
  CREATE DATABASE ambari;
  

配置NTP服务器

• 查看是否安装过，安装过先卸载

  rpm -qa | grep ntp
  

• 安装

  yum install ntp ntpdate -y
  

服务器端

使该NTP服务器在不联网的情况下，使用本服务器的时间作为同步时间

vim /etc/ntp.conf

把如下四行代码注释掉

server 0.centos.pool.ntp.org iburst
server 1.centos.pool.ntp.org iburst
server 2.centos.pool.ntp.org iburst
server 3.centos.pool.ntp.org iburst

在下面再添加一行

server 127.127.1.0 iburst

客户端

将刚刚搭建好的NTP服务器作为客户端上游时间服务器

vim /etc/ntp.conf

内容修改如下：

#注释掉其他上游时间服务器
#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
#配置上游时间服务器为本地的ntpd Server服务器
server 192.168.1.2
#配置允许上游时间服务器主动修改本机的时间
restrict 192.168.1.2 nomodify notrap noquery

• 在所有机器上执行

[root@node2 ~]# systemctl start ntpd.service  
[root@node2 ~]# systemctl enable ntpd.service  
[root@node2 ~]# ntpdate -u 192.168.1.2

搭建本地源

首先要查看ambari支持的HDP版本点击这里

# 安装httpd
yum -y install httpd.x86_64
systemctl enable httpd.service
systemctl start httpd.service
# 将tar包下载到/var/www/html
cd /var/www/html

新建Repo文件

在/etc/yum.repos.d/目录下，新建ambari.repo、HDP.repo和HDP-GPL.repo文件，内容分别如下：

• ambari.repo文件

[ambari]
name=ambari
baseurl=http://192.168.201.12/ambari/centos7/2.6.2.2-1/
enabled=1
gpgcheck=0

• HDP.repo文件

[HDP]
name=HDP
baseurl=http://192.168.201.12/HDP/centos7/2.6.5.0-292/
path=/
enabled=1
gpgcheck=0

[HDP-UTILS]
name=HDP-UTILS
baseurl=http://192.168.201.12/HDP-UTILS/centos7/1.1.0.22/
path=/
enabled=1
gpgcheck=0

• HDP-GPL.repo文件

[HDP-GPL]
name=HDP-UTILS
baseurl=http://192.168.201.12/HDP-GPL/centos7/2.6.5.0-292/
path=/
enabled=1
gpgcheck=0

将新建的文件同步到所有的机器上。然后每台机器都要执行：

yum clean all
yum makecache
yum repolist

安装

yum -y install ambari-server

解决方式:
编辑ambari-agent.ini 配置文件
在 [security] 下面增加一行代码 [force_https_protocol=PROTOCOL_TLSv1_2 ]

  # 所有节点均要加
  vi /etc/ambari-agent/conf/ambari-agent.ini

修改上述文件之后,重启ambari-server即可

ambari-server stop

ambari-server setup  # 为了保证成功,使用该命令,直接重启跳过该过程亦可
ambari-server start
