Ambari部署

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

免密登陆

各个主机均执行以下操作：

## 生成密钥对

ssh-keygen -t rsa   ## 一路回车即可

## 进入.ssh目录，如果目录不存在则创建

cd ~/.ssh

## 将公钥导入至authorized_keys

cat id_rsa.pub >> authorized_keys

## 修改文件权限

chmod 700 ~/.ssh

chmod 600 authorized_keys

扔钥匙多主机免密这块就略过了

同时省略了 安装JDK和安装Mysql的步骤

登入Mysql 

mysql -u root -p

新增ambari用户并增加权限

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'@'hdp01' IDENTIFIED BY 'ambari';

GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'hdp01';  //本地主机名

FLUSH PRIVILEGES;

使用ambari用户登陆并创建数据库

mysql -uambari -pambari

CREATE DATABASE ambari;

exit;

安装httpd和wget服务

# 安装httpd

yum -y install httpd.x86_64

systemctl enable httpd.service

systemctl start httpd.service

# 安装wget

yum -y install wget

ambari和hdp包自行获取哈  

然后把包放在/var/www/html/

新建repo文件

新建ambari.repo文件

[ambari]

name=ambari

baseurl=http://hadoop01/ambari/centos7/2.7.5.0-72/

enabled=1

gpgcheck=0

放入/etc/yum.repos.d/目录下。

在主节点安装ambari-server

安装

yum -y install ambari-server

将mysql-connector-java.jar包拷贝到/usr/share/java目录下

修改配置文件

echo server.jdbc.driver.path=/usr/share/java/mysql-connector-java.jar >> /etc/ambari-server/conf/ambari.properties

安装ambari-server

ambari-server setup

如下是打印输出：

[root@hadoop01 yum.repos.d]# ambari-server setup

这里注意一下

卸载SmartSense包

HDP这边有个组件 是SmartSense 这个是一个收费的东西 HDP为了赚money的一个组件 我们要先给他干掉

首先把这些包查出来删掉

rm -rf /var/lib/ambari-server/resources/stacks/HDP/2.1/services/SMARTSENSE

rm -rf /var/lib/ambari-server/resources/stacks/HDP/3.0/services/SMARTSENSE

rm -rf /var/lib/ambari-agent/cache/stacks/HDP/2.1/services/SMARTSENSE

rm -rf /var/lib/ambari-agent/cache/stacks/HDP/3.0/services/SMARTSENSE

启动ambari-server 

开始部署

往下面划  选择使用本地的源

Confirm Hosts

日志中就会有hostlist 也就是之前那里填写的那些

然后就会检查主机环境

我这边没有遇到什么错误 检查通过了 有问题的可以留言 我们可以一起看看的

Assign Slaves and Clients

这里客户端 我全都装了 装了3个

下一步 接下来就是更加详细的一些信息了

Install,Start and Test

安装完成了
