查看是否开启transparent_hugepage
redhat
cat /sys/kernel/mm/redhat_transparent_hugepage/enabled
其它
cat /sys/kernel/mm/transparent_hugepage/enabled
[always] madvise neveralways代表开启
不存在该文件就是没开启
临时关闭
echo never > /sys/kernel/mm/transparent_hugepage/defrag/etc/hosts配置模板：

下列配置都会报错

环境是在root用户下搭建
apt-get install ntp
service ntp start
1.ssh免密码登陆
2.cd /etc/apt/sources.list.d/
wget http://public-repo-1.hortonworks.com/ambari/ubuntu14/2.x/updates/2.2.0.0/ambari.list或者直接创建ambari.list
#VERSION_NUMBER=2.2.0.0-1310
deb http://public-repo-1.hortonworks.com/ambari/ubuntu14/2.x/updates/2.2.0.0 Ambari main3.
apt-key adv --recv-keys --keyserver keyserver.ubuntu.com B9733A7A07513CAD
apt-get update
apt-get install ambari-serverambari-server 对应的下载地址
http://public-repo-1.hortonworks.com/ambari/ubuntu14/2.x/updates/2.2.0.0/pool/main/a/ambari-server/ambari-server_2.2.0.0-1310_amd64.deb
（路径：/var/cache/apt/archives/ambari-server_2.2.0.0-1310_amd64.deb）为了加快速度可以将ambari-server_2.2.0.0-1310_amd64.deb拷贝到/var/cache/apt/archives/下，再执行apt-get install ambari-server
- ambari-server setup
Downloading JDK from http://public-repo-1.hortonworks.com/ARTIFACTS/jdk-8u60-linux-x64.tar.gz to /var/lib/ambari-server/resources/jdk-8u60-linux-x64.tar.gz
为了加快速度可以将jdk-8u60-linux-x64.tar.gz拷贝到/var/lib/ambari-server/resources/下，再执行ambari-server setup
全部回车，默认，或者如果选择mysql的话
apt-get install libmysql-java
hostname:127.0.0.1
根据指导，进行建表
（通过/etc/ambari-server/conf/ambari.properties文件，貌似可以修改要安装的软件包）
5.ambari-server start
此时server安装完成
6.测试

admin admin

oozie配置：
ambari-server setup --jdbc-db=mysql --jdbc-driver=/data/mysql-connector-java-5.1.31-bin.jar选择create new MySQL项
安装mysql
sudo apt-get install mysql-server
apt-get isntall mysql-client
sudo apt-get install libmysqlclient-devoozie连接MySQL的设置
jdbc url:
jdbc:mysql://localhost:3306/oozie
mysql设置
mysql -uroot -p
create database oozie;
create user 'oozie'@'%' identified by 'oozie';
GRANT ALL PRIVILEGES ON *.* TO 'oozie'@'%' WITH GRANT OPTION;
grant all on *.* to oozie@'localhost' identified by 'ooze';
flush privileges; 重新配置集群：
ambari-server stop删除mysql中的ambari数据库
重新建ambari
source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sqlambari-server start
