Ambari+Bigtop大数据平台安装部署指南(Centos7)一

前言

安装部署分为以下五个大步骤

1.资源准备

2.操作系统配置

3.数据库配置

4.ambari配置

5.bigtop组件安装

必要说明

all 表示全部主机都要执行

server表示ambari-server安装的主机执行

${key}表示需要根据实际情况修改的变量，例如${server.ip}应替换成server所在主机的ip，所有变量均会标红

资源准备

需要准备3台centos7虚拟机，建议规格4C16G60G；ambari2.8.0、ambari-metrics3.0.0、bigtop3.2.0三类组件

方式一：

按上篇文章的方式自己编译组件

方式二：

echo "编-译-好-的-包-放-在-群-文-件-里-了"
echo "欢-迎-加-Q-Q-群-进-行-交-流"
echo "7-2-2-0-1-4-9-1-2"

操作系统配置

基础配置

检查操作系统版本一致性(all)

cat /etc/redhat-release

设置操作系统默认语言(all)

localectl set-locale LANG=en_US.UTF-8
要求：en_US.UTF-8

设置操作系统时区(all)

cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
要求CST +0800

设置机器名(all)

echo "${hostname}" > /etc/hostname

设置域名解析(all)

echo "${ip1} ${hostname1}" >> /etc/hosts
echo "${ip2} ${hostname2}" >> /etc/hosts
echo "${ip3} ${hostname3}" >> /etc/hosts
注意：要将集群每台机器的ip hostname都添加到hosts中

设置网络(all)

echo "NETWORKING=yes" > /etc/sysconfig/network

关闭防火墙(all)

#停止防火墙
systemctl stop firewalld
#关闭防火墙
systemctl disable firewalld

关闭selinux(all)

setenforce 0
echo "SELINUX=disabled" > /etc/selinux/config
echo "SELINUXTYPE=targeted" >> /etc/selinux/config

配置limits参数(all)

echo "* hard nproc 65535" > /etc/security/limits.conf
echo "* soft nproc 65535" >> /etc/security/limits.conf
echo "* hard nofile 65535" >> /etc/security/limits.conf
echo "* soft nofile 65535" >> /etc/security/limits.conf

禁用交换分区(all)

sysctl vm.swappiness=0
echo "vm.swappiness=0" >> /etc/sysctl.conf

设置umask(all)

echo umask 0022 >> /etc/profile
source /etc/profile

磁盘挂载(all)

#1.用lsblk命令查看磁盘挂载情况(以sdb为例)

#2.创建挂载的文件夹（有多少块待挂载的磁盘就在/下建多少个data{i}文件夹，i从1开始）
mkdir ${/data1}

#3.修改磁盘分区模式
parted -s ${/dev/sdb} mklabel gpt

#4.分区
parted -s ${/dev/sdb} mkpart primary 0% 100%

#5.格式化
mkfs.ext4 ${/dev/sdb1}

#6.挂载
mount ${/dev/sdb1} ${/data1}

#7.开机自动挂载
echo '${/dev/sdb1} ${/data1} ext4 defaults 0 0' >> /etc/fstab

重启(all)

reboot命令重启以确保基础配置生效

免密(server)

生成密钥

ssh-keygen -f ~/.ssh/id_rsa -t rsa -N ''

发送公钥到全部机器 包括自己

ssh-copy-id -i ~/.ssh/id_rsa.pub root@${hostname1}

ssh-copy-id -i ~/.ssh/id_rsa.pub root@${hostname2}

ssh-copy-id -i ~/.ssh/id_rsa.pub root@${hostname3}

基础软件安装(all)

yum -y groupinstall "Infrastructure Server" --setopt=group_package_types=mandatory,default,optional

yum -y groupinstall "Development Tools" --setopt=group_package_types=mandatory,default,optional

配置ntp服务

服务端(server)

echo "server 127.0.0.1" >> /etc/ntp.conf

echo "fudge 127.0.0.1 stratum 10" >> /etc/ntp.conf

systemctl restart ntpd.service

客户端(all)

echo "server ${server.ip}" >> /etc/ntp.conf

systemctl restart ntpd.service

systemctl enable ntpd

关闭chrony自启动，否则ntp服务不会自启动

systemctl disable chronyd

安装离线镜像源(server)

上传软件

将bigdatarepo上传到~目录

复制软件

cp -r ~/bigdatarepo /var/www/html/

启动httpd服务

#启动

systemctl start httpd

#开机自启

systemctl status httpd.service

配置离线镜像源(all)

创建配置文件

cat > /etc/yum.repos.d/ambari.repo <<EOF

[ambari]
name=ambari
baseurl=http://${server.ip}/bigdatarepo
failovermethod=priority
enabled=1
gpgcheck=0

EOF

生效

yum clean all

yum makecache

数据库设置(server)

#安装

yum –y install mariadb-server mysql-connector-java

#启动

systemctl start mariadb

#开机自启

systemctl enable mariadb

#设置密码

mysql -uroot -e "set password = password('abcd1234');flush privileges;"

#删除空账户

mysql -uroot -pabcd1234 -e "use mysql;delete from user where User='';flush privileges;"

ambari配置(server)

创建数据库

#创建数据库

mysql -uroot -pabcd1234 -e "create database ambari;create database hive;"

#创建用户并授权

mysql -uroot -pabcd1234 -e "use ambari; create user 'ambari'@'%' identified by 'ambari123' ;GRANT ALL PRIVILEGES on . To 'ambari'@'%' IDENTIFIED BY 'ambari123'; FLUSH PRIVILEGES;"

mysql -uroot -pabcd1234 -e "use hive; create user 'hive'@'%' identified by 'ambari123' ;GRANT ALL PRIVILEGES on . To 'hive'@'%' IDENTIFIED BY 'ambari123'; FLUSH PRIVILEGES;"

安装启动ambari(server)

安装

yum –y install ambari-server

设置

ambari-server setup

初始化ambari-server数据

mysql -uroot -pabcd1234 -e "use ambari;source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql;show tables;"

启动ambari-server

ambari-server start

至此，ambari已经安装完成
