准备工作：(系统centos6) （推荐java1.7以上版本）
?
每台机器安装:
? #yum install -y mesa-libGL.i686
? #yum install openssl
???? [安装时遇到openssl问题# rpm -qa|grep openssl
???? # rpm -e openssl-1.0.1e-15.el6.x86_64
???? # rpm -Uvh openssl-devel-1.0.0-27.z.2.ec1.gf.el6.x86_64.rpm]
#yum install nc
#yum install gcc
#yum install python-libs
? 关闭?Linux?的?THP?服务(#centos6)
? # echo transparent_hugepage=never >> /etc/grub.conf
? #echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
? #yum install ntp
? # chkconfig ntpd on && service ntpd start
? (失败vim /etc/ntp.conf? 添加ntpd_enable="YES")
关闭?SELinux?服务，关闭防火墙，
#chkconfig iptables off && service iptables stop && setenforce 0
修改/etc/selinux/config文件中的SELINUX="" 为 disabled。
? # mkdir -p /var/lib/ambari-agent/data
? #date –s 2015-12-01 17:36校准时间
? #/etc/init.d/sshd restart
? #yum clean all && yum makecache
?
?
第一台机器安装:
? #yum install createrepo （安装??createrepo?，用于制作本地源）
?
? 配置环境：httpd?服务
? #vi /etc/httpd/conf/httpd.conf
? 把??#ServerName??www.example.com?:80??修改为?ServerName?hostname:80
修改访问权限：
<Directory />
? Options FollowSymLinks
? AllowOverride None
</Directory>
启动?httpd?服务
#chkconfig httpd on && service httpd start
?
下载?HDP??和?HDP-UTILS?：?
#wget -nv http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.3.0.0/hdp.repo -O /etc/yum.repos.d/hdp.repo
#同步
#Yum repolist
???? #reposync -r HDP-2.3.2.0
#reposync -r HDP-UTILS-1.1.0.20
下载?Amabri?：
# wget -nv http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.1.2.1/ambari.repo -O /etc/yum.repos.d/ambari.repo
#同步
#yum repolist
? # reposync -r Updates-ambari-2.1.2.1
在/etc/yum.repo.d文件夹中添加一个 ambari.repo文件，内容如下：
[ambari]
name=ambari repo
baseurl=http://192.168.145.138/ambari
gpgcheck=0
enabled=1
# mkdir /var/www/html/ambari
把上面下载的文件夹移动到abmari下
#createrepo /var/www/html/ambari
#yum clean all && yum makecache
# yum install ambari-server
#ambari-server setup
# ambari-server start
?
1.准备至少3台机器, 依次配置每台机器的主机名,第一台机器同时作为yum本地源
【
配置主机名3步
1.#hostname hdp1
2.# vim /etc/sysconfig/network
? HOSTNAME=hdp1
3.# vim /etc/hosts
192.168.144.63 hdp1
192.168.144.64 hdp2
192.168.144.70 hdp3
】
2.设置hdp1免密码登陆hdp2,hdp3
【
? hdp1上执行:
? #ssh-keygen?-t?rsa （3次回车）
? # scp?~/.ssh/id_rsa.pub?root@hyj1:~/
? # scp?~/.ssh/id_rsa.pub?root@hyj2:~/
? # scp?~/.ssh/id_rsa.pub?root@hyj3:~/
? 每台机器上执行:
? #vim /etc/ssh/sshd_config? (打开下面3行的注释)
???? ? RSAAuthentication?yes
PubkeyAuthentication?yes
AuthorizedKeysFile??????.ssh/authorized_keys
? # cat?~/id_rsa.pub?>>?~/.ssh/authorized_keys??
】
?
3.访问hdp1:8080安装
注意：
Select Stack> Advanced Repository Options指定本地源
? 安装ambari-agent选择的sshkey是id_rsa
? #mkdir /var/lib/ambari-agent/data
? 安装agent报错
? vi /etc/ambari-agent/conf/ambari-agent.ini
[server]
hostname=<your.ambari.server.hostname>
url_port=8440
secured_url_port=8441
?
ambari重新部署hadoop删除脚本
【
#!/bin/sh
?
echo "start del dir"
?
rm -rf /var/lib/hadoop-yarn
rm -rf /var/lib/hadoop-mapreduce
rm -rf /etc/hadoop
rm -rf /etc/hbase
rm -rf /etc/zookeeper
rm -rf /var/run/hadoop
rm -rf /var/run/hbase
rm -rf /var/run/zookeeper
rm -rf /var/log/hadoop
rm -rf /var/log/hbase
rm -rf /var/log/zookeeper
rm -rf /usr/lib/flume
rm -rf /usr/lib/storm
rm -rf /var/lib/hadoop-hdfs
rm -rf /tmp/hadoop-hdfs
rm -rf /hadoop/hbase
?
echo "start del user"
?
userdel hadoop
userdel hbase
userdel ambari-qa
userdel zookeeper
userdel hdfs
userdel ams
userdel yarn
userdel mapred
?
echo "complete"
?
