ambari-2.7.1.0-centos7.tar.gz

本文以 ambari-2.6.2.2 、 HDP-2.6.5.0 、 HDP-UTILS-1.1.0.22 、HDP-GPL-2.6.5.0 为例搭建ambari集群。

官网地址：

ambari ：https://docs.cloudera.com/HDPDocuments/Ambari-2.6.2.2/bk_ambari-installation/content/ambari_repositories.html

hdp：https://docs.cloudera.com/HDPDocuments/Ambari-2.6.2.2/bk_ambari-installation/content/hdp_26_repositories.html

一、下载对应版本的镜像包


wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.6.2.2/ambari.repo
wget http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.6.2.2/ambari-2.6.2.2-centos7.tar.gz
wget http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.6.5.0/hdp.repo
wget http://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.6.5.0/HDP-2.6.5.0-centos7-rpm.tar.gz
wget http://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.22/repos/centos7/HDP-UTILS-1.1.0.22-centos7.tar.gz
wget http://public-repo-1.hortonworks.com/HDP-GPL/centos7/2.x/updates/2.6.5.0/HDP-GPL-2.6.5.0-centos7-gpl.tar.gz

二、基础环境配置


1.修改主机名
 
2.修改映射
 
3.修改文件打开限制
[root@master ~]# vi /etc/security/limits.conf
# End of file
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072
 
4.关闭防火墙
[root@master~]#systemctl disable firewalld
[root@master~]#systemctl stop firewalld
 
5.免密码登录
 
6.安装jdk8

三、安装httpd服务


yum install -y httpd
systemctl start httpd
systemctl enable httpd

四、配置yum源


# 创建文件夹
mkdir -p /var/www/html/ambari
 
# 解压至文件夹
tar -zxvf ambari-2.6.2.2-centos7.tar.gz -C /var/www/html/ambari
tar -zxvf HDP-2.6.5.0-centos7-rpm.tar.gz -C /var/www/html/ambari
tar -zxvf HDP-UTILS-1.1.0.22-centos7.tar.gz -C /var/www/html/ambari
tar -zxvf HDP-GPL-2.6.5.0-centos7-gpl.tar.gz -C /var/www/html/ambari
 
# 复制ambari.repo、hdp.repo到yum
cp ambari.repo /etc/yum.repos.d/
cp hdp.repo /etc/yum.repos.d/
 
# 修改ambari.repo(ip为httpd主机ip)

# 将repo复制到其他节点(所有节点)
scp /etc/yum.repos.d/ambari.repo  server2:/etc/yum.repos.d/
scp /etc/yum.repos.d/hdp.repo     server2:/etc/yum.repos.d/
 
# 更新yum(所有节点)
yum clean all
yum makecache
yum update

五、安装ntp时间同步服务器

服务端


# 安装
yum -y install ntp
 
# 配置
vi /etc/ntp.conf
##############################################################
//将这行给注释
#restrict default nomodify notrap nopeer noquery      
 
//然后添加这两行 ，意思是 允许IPV4 IPV6 查询 拒绝修改
restrict -4 default kod notrap nomodify    
restrict -6 default kod notrap nomodify
 
//添加修改上层时间服务器，如果能联通外网，则不需要修改，
server 0.rhel.pool.ntp.org iburst
server 1.rhel.pool.ntp.org iburst
server 2.rhel.pool.ntp.org iburst
server 3.rhel.pool.ntp.org iburst
//如果联不通外网，则把上面几行注释，然后添加下面两行，意思是设置成时间服务器是自己
server 127.127.1.0
fudge 127.127.1.0 stratum 8
##############################################################
 
# 启动
systemctl  start  ntpd

客户端


# 安装
yum -y install ntp
 
# 加入定时器
crontab -e
#############################################
0 * * * * /usr/sbin/ntpdate 192.168.2.101
#############################################
 
 
 
 
或者
vim /etc/ntp.conf
#############################################
server master主机ip  iburst
#############################################

六、安装mysql5.7

安装（不能装mysql8.X）

https://blog.csdn.net/qq_23160237/article/details/102467487

创建用户以及赋权


# 登录
mysql -uroot -p
 
# 赋权
create database ambari character set utf8;
Create user 'ambari' identified by 'ambari';
grant all privileges on *.* to 'ambari';
Flush privileges;
 
create database hive character set utf8;
create user 'hive' identified by 'hive';
grant all privileges on *.* to 'hive';
flush privileges;

七、安装ambari

yum install ambari-server

八、导入初始化数据

使用ambari用户登录：mysql -uambari -p

九、导入Mysql驱动


yum install mysql-connector-java
cp /usr/share/java/mysql-connector-java.jar /var/lib/ambari-server/resources/mysql-connector-java.jar
ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar
vi /etc/ambari-server/conf/ambari.properties
添加server.jdbc.driver.path=/usr/share/java/mysql-connector-java.jar
 
或者
 
mkdir /usr/share/java
cp mysql-connector-java-5.1.48.jar /usr/share/java/mysql-connector-java.jar
cp /usr/share/java/mysql-connector-java.jar /var/lib/ambari-server/resources/
vi /etc/ambari-server/conf/ambari.properties
添加server.jdbc.driver.path=/usr/share/java/mysql-connector-java.jar

十、配置ambari


[root@master ~]# ambari-server setup

十一、启动服务

ambari-server start

十二、服务安装

1）登录

登录界面，默认管理员账户登录，账户：admin 密码：admin

2）配置集群的名字为hadoop

3）选择版本并修改为本地源地址

（3）安装配置

（4）安装ambari的agent，同时检查系统问题

（5）选择要安装的服务

（6）选择分配服务

十三、错误处理

如果以上步骤出现错误，查看日志（/var/log/ambari-server/ambari-server.log）

或者根据以下步骤重置重新安装


[root@master ~]# ambari-server stop
[root@master ~]# ambari-server reset
[root@master ~]# ambari-server setup


[root@master ~]# mysql -uroot -p
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| ambari             |
| hive               |
| oozie              |
| performance_schema |
+--------------------+
rows in set (0.00 sec)
mysql> drop database ambari;
mysql> drop database hive;

常见报错：

1. hbase启动后，运行报错：

Caused by: org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /atsv2-hbase- unsecure/hbaseid

修改：ZooKeeper Znode Parent 的value为正确路径

2. hbase启动后，运行报错：

ServerNotRunningYetException: Server is not running yet

解决方案：

1）hdfs退出安全模式：sudo -u hdfs hadoop dfsadmin -safemode leave

3..hbase启动后，运行报错：

PleaseHoldException: Master is initializing

解决方案：

1）HBase root directory ：修改为hdfs路径（hdfs://namenode-ha:8020/hbase）

卸载ambari


rm -rf /var/cache/yum/x86_64/7/*
rm -rf /usr/share/doc/smartsense-*
yum remove smartsense-hst
rm -rf /var/log/smartsense/
