最近我负责安装了学院服务器集群系统和管理大数据应用服务的Apache Ambari + HDP，分享一下过程。
目录
软件版本
| 软件名称 | 版本 |
|---|---|
| JDK | Oracle jdk1.8.0_151 |
| MySQL | 5.7.35 MySQL Community Server (GPL) |
| Ambari | 2.7.5 |
| HDP | 3.1.5 |
修改主机名
vi /etc/hosts
******** node1
******** node2
******** node3
******** node6
关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
# 禁用selinux
vi /etc/selinux/config
SELINUX=disabled
setenforce 0
安装基础组件
# 安装httpd
yum -y install httpd.x86_64
systemctl enable httpd.service
systemctl start httpd.service
# 安装wget
yum -y install wget
安装MySQL
# mysql 5.7 centos7
rpm -qa | grep mysql
# 删除相关rpm包
rpm -ev <rpm包名> --nodeps
wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
yum -y install mysql57-community-release-el7-11.noarch.rpm
# 安装第一步下载的rpm文件，安装成功后/etc/yum.repos.d/目录下会增加两个文件
yum repolist enabled | grep mysql
# 查看mysql57的安装源是否可用，如不可用请自行修改配置文件（/etc/yum.repos.d/mysql-community.repo）使mysql57下面的enable=1
# 若有mysql其它版本的安装源可用，也请自行修改配置文件使其enable=0
yum install mysql-community-server
service mysqld start
# 启动mysql服务
grep "password" /var/log/mysqld.log
# 查看root密码
mysql -u root -p
# 登陆mysql
Enter password:
# 为了可以设置简单密码
set global validate_password_policy=0;
set global validate_password_length=4;
# 立即修改密码，执行其他操作报错：
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('********');
# 我们创建密码为********
# 新增ambari用户并增加权限
mysql -uroot -pCentos@rjxy
CREATE USER 'ambari'@'%' IDENTIFIED BY '********';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'%';
CREATE USER 'ambari'@'localhost' IDENTIFIED BY '********';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'localhost';
CREATE USER 'ambari'@'node1' IDENTIFIED BY '********';
GRANT ALL PRIVILEGES ON *.* TO 'ambari'@'node1';
FLUSH PRIVILEGES;
# mysql -uambari -pambari
CREATE DATABASE ambari;
exit;
安装jdk
yum install java-1.8.0-openjdk
wget https://repo1.maven.org/maven2/mysql/mysql-connector-java/5.1.47/mysql-connector-java-5.1.47.jar
mv mysql-connector-java-5.1.47.jar /usr/lib/jvm/java-1.8.0-openjdk/lib
vi /etc/profile
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/mysql-connector-java-5.1.47-bin.jar
export PATH=$JAVA_HOME/bin:${PATH}
source /etc/profile
java -version
配置免密登录
出于安全考虑，只配置1号机到2/3/6号机器上的免密登录。
- 在四台机器上都执行
ssh-keygen -t rsa后，执行cd ~/.ssh && cat id_rsa.pub >> authorized_keys && chmod 700 ~/.ssh && chmod 600 authorized_keys - 在1号机上执行：
cat ~/.ssh/id_rsa.pub | ssh root@node2 'cat - >> ~/.ssh/authorized_keys'
cat ~/.ssh/id_rsa.pub | ssh root@node3 'cat - >> ~/.ssh/authorized_keys'
cat ~/.ssh/id_rsa.pub | ssh root@node6 'cat - >> ~/.ssh/authorized_keys'
