怎么修改ambari中的hadoop配置文件

Posted 2023-05-16

参考技术A 1，通过ambari将集群中的所用组件都关闭，如果关闭不了，直接kill -9 XXX
2，关闭ambari-server，ambari-agent
ambari-server stop
ambari-agent stop本回答被提问者采纳 参考技术B advantage of meeting Dr. Mortimer and

Ambari2.7.3和HDP3.1.4在线安装

linux设置

配置hosts
vim /etc/hosts
192.168.1.9 Hadoop01
ssh免密
ssh-keygen -t rsa
ssh-copy-id -i ~/.ssh/id_rsa.pub root@Hadoop01
修改文件描述符限制
vim /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072
关闭SELinux
vi /etc/selinux/config
将SELINUX=enforcing改为SELINUX=disabled 
关闭防火墙
systemctl stop firewalld.service
systemctl disable firewalld.service
修改主机为英文
vi /etc/locale.conf
LANG="en_US.UTF-8"

 

安装mysql

初始化mysql

CREATE DATABASE ambari;  
use ambari;  
CREATE USER ‘ambari‘@‘%‘ IDENTIFIED BY ‘ambari123‘;  
GRANT ALL PRIVILEGES ON *.* TO ‘ambari‘@‘%‘;  
CREATE USER ‘ambari‘@‘localhost‘ IDENTIFIED BY ‘ambari123‘;  
GRANT ALL PRIVILEGES ON *.* TO ‘ambari‘@‘localhost‘;  
CREATE USER ‘ambari‘@‘hadoop01‘ IDENTIFIED BY ‘ambari123‘;  
GRANT ALL PRIVILEGES ON *.* TO ‘ambari‘@‘hadoop01‘;  
FLUSH PRIVILEGES;  
source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql 
CREATE DATABASE hive;
use hive;
CREATE USER ‘hive‘@‘%‘ IDENTIFIED BY ‘ambari123‘;
GRANT ALL PRIVILEGES ON *.* TO ‘hive‘@‘%‘;
CREATE USER ‘hive‘@‘localhost‘ IDENTIFIED BY ‘ambari123‘;
GRANT ALL PRIVILEGES ON *.* TO ‘hive‘@‘localhost‘;
CREATE USER ‘hive‘@‘hadoop01‘ IDENTIFIED BY ‘ambari123‘;
GRANT ALL PRIVILEGES ON *.* TO ‘hive‘@‘hadoop01‘;
FLUSH PRIVILEGES; 

CREATE DATABASE oozie;
use oozie;  CREATE USER ‘oozie‘@‘%‘ IDENTIFIED BY ‘ambari123‘;
GRANT ALL PRIVILEGES ON *.* TO ‘oozie‘@‘%‘;  
CREATE USER ‘oozie‘@‘localhost‘ IDENTIFIED BY ‘ambari123‘;  
GRANT ALL PRIVILEGES ON *.* TO ‘oozie‘@‘localhost‘;  
CREATE USER ‘oozie‘@‘hadoop01‘ IDENTIFIED BY ‘ambari123‘;  
GRANT ALL PRIVILEGES ON *.* TO ‘oozie‘@‘hadoop01‘;  
FLUSH PRIVILEGES;

 

这里我们需要在数据库中分别创建ambari数据库和ambari用户，注意这里有一个坑：数据库密码只能输入字符数字和 _下划线，还有-减号。不能包含特殊字符，否则会报以下错误信息：
Enter Database Password (bigdata):
Invalid characters in password. Use only alphanumeric or _ or - characters12
而MySQL 5.7默认安全策略是中级的，需要有特殊字符，这个可以通过以下命令进行修改，使用root用户登录mysql数据库服务器：

set global validate_password_policy=0;
flush privileges;

 

在线安装ambari

wget -nv http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.7.3.0/ambari.repo -O /etc/yum.repos.d/ambari.repo
yum repolist
yum install ambari-server -y

初始化设置setup

ambari-server setup
根据提示配置$JAVA_HOME，mysql数据库等信息
ambari-server setup --jdbc-db=mysql --jdbc-driver=/export/service/hdp/mysql-connector-java-5.1.47-bin.jar

mysql-connector-java-5.1.47-bin.jar下载地址：
https://downloads.mysql.com/archives/c-j/

启动

ambari-server start

访问Ambari web页面

默认端口8080，Username：admin Password：admin
http://192.168.1.9:8080

安装hdp3.1.4

根据提示操作即可，安装过程非常慢。。。
