centos6.7 mini ambari hadoop

系统环境，请查看《virtualbox5.0.8 centos6.7 mini 安装》

规划：3台机器集群

软件：

ambari-2.1.2

hdp 2.3.2.0

HDP-UTILS-1.1.0.20

vi /etc/hosts

192.168.56.41 hdp01.myhadoop.com

192.168.56.42 hdp02.myhadoop.com

192.168.56.43 hdp03.myhadoop.com

#每台机器都一样

service iptables stop

chkconfig iptables off

#设置时间同步

请参考《centos 局域网时间同步设置》

#安装jdk

请参考《centos6.7 mini 安装oracle jdk 1.8》

#安装依赖软件

yum -y install python openssh-clients

#配置3台服务器互相无密码登录

ssh-keygen -t rsa

#一路回车

ssh-copy-id hdp01.myhadoop.com

ssh-copy-id hdp02.myhadoop.com

ssh-copy-id hdp03.myhadoop.com

#登录每台机器验证

ssh 'hdp01.myhadoop.com'

ssh 'hdp02.myhadoop.com'

ssh 'hdp03.myhadoop.com'

vi /etc/rc.local

echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag

echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled

echo never > /sys/kernel/mm/transparent_hugepage/enabled

echo never > /sys/kernel/mm/transparent_hugepage/defrag

并手动执行以上4条命令

vi /etc/sysctl.conf

vm.swappiness=5

mkdir -p /usr/share/java

#我使用的是mysql5.6，所以用的是mysql-connector-java-5.1.35.jar

上传到/usr/share/java 并重命名为mysql-connector-java.jar

ambari.repo

#在hdp01.myhadoop.com上执行以下命令

scp /usr/share/java/mysql-connector-java.jar root@hdp03.myhadoop.com:/usr/share/java

scp /usr/share/java/mysql-connector-java.jar root@hdp03.myhadoop.com:/usr/share/java

yum -y install ambari-server

ambari-server setup

ambari-server start

cat /root/.ssh/id_rsa
