在虚拟机上安装Centos6.5操作系统，建议使用64位的操作系统。
修改系统自带的yum源，使用国内的yum源的话yum的速度会快一点 1、备份系统源 # cd /etc/yum.repos.d # mv CentOS-Base.repo CentOS-Base.repo.bak 2、设置默认源为163 # wget http://mirrors.163.com/.help/CentOS6-Base-163.repo # mv CentOS6-Base-163.repo CentOS-Base.repo 3、执行yum源更新 # yum clean all // 清除以前的缓存 # yum makecache // 重建缓存 # yum update
关闭防火墙
1、重启后永久性生效： 开启：chkconfig iptables on 关闭：chkconfig iptables off 2、关闭SELinux sudo gedit /etc/selinux/config # 改为 SELINUX=disabled
安装ntp,保证系统时间一致
yum install ntp service ntpd start
更新openssl 、 python
yum upgrade openssl yum update python
安装ssh免密码登陆
ssh-keygen -t rsa一路回车 cd /root/.ssh/ cp id_rsa.pub authorized_keys chmod 600 authorized_keys cd /root/ chmod 700 -R .ssh
卸载centos6.5自带的JDK，安装自己的JDK
rpm -qa | grep java 把出现的文件全部删掉，例如： rpm -e --nodeps tzdata-java-2013g-1.el6.noarch rpm -e --nodeps java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64 rpm -e --nodeps java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64 上传新的jdk 解压，配置环境变量 sudo gedit /etc/profile 增加一下内容： JAVA_HOME=/usr/java/jdk1.7.0_79 JRE_HOME=/usr/java/jdk1.7.0_79/jre PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin CLASSPATH=:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib export JAVA_HOME JRE_HOME PATH CLASSPATH 使修改的文件生效: source /etc/profile
sudo gedit /etc/hosts
安装ambari
cd /etc/yum.repos.d/ wget http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.2.0.0/ambari.repo yum install ambari-server
在此要先关闭这台虚拟机，克隆多两台虚拟机，然后配置网络，相互ssh。例如 在amaster中：
ssh aslave1 y exit ssh aslave2 exit
确认无误之后回到amaster执行

在浏览器输入：amaster:8080 登陆的帐密：admin admin 安装到倒数第二步的时候经常会出错，一般情况下是网络问题，你可以点击 retry 或者你可以看哪个服务安装失败了，直接去失败的虚拟机yum.例如 然后直接去node3中执行一条命令,其他软件安装出错也可以这样做
yum install spark_2_2_*
