服务启动

# 进入容器 启动服务
Systemctl restart krb5kdc
Systemctl restart kadmin

docker-compose-base.yml 启动基础环境

Ambari启动

# 启动基础环境
docker-compose -f docker-compose-base.yaml up -d
# 启动ambari , 在此容器中安装集群
docker-compose -f docker-compose-ambari.yaml up -d

2.4 集群安装

repo地址

节点和秘钥

agent安装

服务安装

由于是单机直接下一步

安装组件

输入密码

数据目录确认

用户确认下一步

服务参数确定

发布

安装完成

2.5 容器导出为像

docker ps -a
docker commit  容器ID ambari-1.0.tar.gz

三、Ubuntu环境安装测试

3.1 环境准备

我们准备Ubuntu 环境，在Ubuntu环境安装Ambari单机，相当于在Centos服务器安装的docker化的Ambari 导出为镜像 然后在Ubutntu 环境尝试启动。 

准备Ubuntu 环境，版本：Ubuntu 20.04.5 LTS

将镜像 ambari-1.0.tar.gz 加载到Ubuntu 环境

docker load -i ambari-1.0.tar.gz

MySQL元数据库备份还原（Ambari、hive、ranger）

HDFS、kerberos 备份的数据拷贝到Ubuntu服务器并保持数据文件路径不变。

将在centos 安装完成的集群备份元数据库写入到新的库中 , 也就是Ubuntu环境要使用的元数据库。

# 备份的元数据写入新的数据库中
mysql -hmysql-test -uroot -pWinner001 ambari  
备份的kerberos和安装包解压
 
# 解压到 /usr 路径下，保存的是集群安装的数据
hdp.tar.gz
# 在根路径解压保留的kerberos 和HDFS 初始化的元数据
hadoop.tar.gz
 
基础环境启动docker-compose-base.yaml

    privileged: true
    restart: always
    volumes:
      - "/etc/hosts:/etc/hosts"
  kdc:
    image: kerberos:1.0
    restart: always
    privileged: true
    networks:
      - hadoop-network
    container_name: kerberos
    hostname: kerberos.winner
    ports:

启动
 
# 启动
docker-compose -f docker-compose-base.yaml up -d
# 停止
docker-compose -f docker-compose-base.yaml down 
 
3.2 集群容器启动
镜像
启动容器
 
version: '3'
services:
  ambari:
    image: ambari:2.7.4  # 修改为新的容器
    container_name: ambari
    hostname: ambari-server
    restart: always
    privileged: true
    networks:
      - hadoop-network
    ports:
      - 8080:8080
      - 8088:8088
      - 50070:50070
      - 50075:50075
      - 8188:8188
      - 8042:8042
      - 10000:10000
      - 9083:9083
      - 6080:6080
      - 16010:16010
    volumes:
      - /etc/hosts:/etc/hosts
      - /usr/hdp:/usr/hdp
      - /hadoop/hdfs:/hadoop/hdfs
      - /hadoop/etc/hadoop/:/etc/hadoop/
      - /hadoop/etc/hbase/:/etc/hbase/
      - /hadoop/etc/hive/:/etc/hive/
      - /hadoop/etc/livy2/:/etc/livy2/
      - /hadoop/etc/spark2/:/etc/spark2/
      - /hadoop/etc/tez/:/etc/tez/
      - /hadoop/etc/zookeeper/:/etc/zookeeper/
      - /hadoop/yarn:/hadoop/yarn
      - /hadoop/kerberos/krb5kdc:/var/kerberos/krb5kdc
      - /hadoop/kerberos/keytabs:/etc/security/keytabs
    command:
      - /bin/sh
      - -c
      - |
        /opt/apache/bootstrap.sh
networks:
  hadoop-network:
    external:
      name: hadoop-network
 
启动
 
docker-compose -f docker-compose-ambari.yaml up -d
 
下次安装直接加载镜像，然后执行yaml文件即可
 
docker load -i ambari-1.0.tar.gz
docker load -i kerberos.tar.gz
docker load -i mysql.tar.gz
docker load -i HDP-REPO.tar.gz
 
脚本
bootstrap.sh
 
#!/bin/bash
set -x

wait_for() {
    echo Waiting for $1 to listen on $2...
    while ! nc -z $1 $2; do echo waiting...; sleep 1s; done
}
setup_ambari() {
  # 强制替换文件
  cp -f /tmp/ambari.properties /etc/ambari-server/conf/ 
  cp -f /tmp/password.dat     /etc/ambari-server/conf/
  cp -f /tmp/ambari-agent.ini    /etc/ambari-agent/conf/
}
# wait for mysql and httpd
#wait_for windp-aio 3306

# 开始ambari安装
yum -y install ambari-server
yum -y install ambari-agent
re=`mysql -h${myurl} -u${myuser} -p${mypwd} -e "show databases"|grep ambari|wc -l`
if [ $re -eq 0 ];then
   # sql 初始化
   mysql -h${myurl} -u${myuser} -p${mypwd}
