Ambari集群部署全流程

#指向yum源地址

baseurl=http://ambari-01/ambari/centos7/2.7.4.0-118/

#关闭下载RPM的jpg校验

gpgcheck=0

#组可用

enabled=1

#查看yum源配置是否生效 & 看到红框内容则成功

yum repolist

4 安装MySQL

---

#安装mysql的yum仓库

sudo wget https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm

rpm -ivh mysql57-community-release-el7-9.noarch.rpm

#安装mysql(必须进入到 /etc/yum.repos.d/目录后再执行以下脚本)

yum install mysql-server

#设置开机启动

sudo systemctl enable mysqld

#启动MySQL

sudo systemctl start mysqld

#查看MySQL的启动状态

sudo systemctl status mysqld

#查看root临时密码(临时密码每次都是随机生成的) (&fZPOuLl19i

sudo grep ‘temporary password’ /var/log/mysqld.log

#使用临时密码登录

mysql -uroot -p

MySQL常用密码参数

set global validate_password_policy=0;

set global validate_password_mixed_case_count=0;

set global validate_password_number_count=3;

set global validate_password_special_char_count=0;

set global validate_password_length=3;

修改密码（‘root’@‘%’ – 允许远程连接）

GRANT ALL PRIVILEGES ON . TO ‘root’@‘%’ IDENTIFIED BY ‘PWD@123456’ WITH GRANT OPTION;

ALTER USER ‘root’@‘%’ IDENTIFIED BY ‘PWD@123456’;

退出MySQL

Exit

上传驱动包mysql-connector-java-8.0.18.jar 到服务器/usr/share/java目录

sudo mkdir -p /usr/share/java

5、部署AmbariServer

---

5.1 安装AmbariServer

sudo yum -y install ambari-server

5.2 创建AmbariServer的数据库资源

#登录MySQL

mysql -uroot -pPWD@123456

#执行如下命令 创建ambari用户并授权

set global validate_password_policy=0;

set global validate_password_mixed_case_count=0;

set global validate_password_number_count=3;

set global validate_password_special_char_count=0;

set global validate_password_length=3;

create database ambari;

CREATE USER ‘ambari’@‘%’ IDENTIFIED BY ‘bigdata’;

GRANT ALL ON ambari.* TO ‘ambari’@‘%’;
