[root@master ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 172.30.15.57 master 172.30.15.58 slaver1 [root@slaver1 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 172.30.15.57 master 172.30.15.58 slaver1 |
503.配置2个节点使用Ambari和iaas中的centos7的yum源。其中Ambari yum源在XianDian-BigData-v2.1-BASE.iso软件包中。
504.在master节点安装ntp时钟服务，使用文件/etc/ntp.conf配置ntp服务；在slaver节点安装ntpdate软件包，将slaver1节点时钟同步到master节点。
505.检查2个节点是否可以通过无密钥相互访问，如果未配置，则进行SSH无密码公钥认证配置。
506.安装2个节点的JDK环境，其中jdk-8u77-linux-x64.tar.gz在XianDian-BigData-v2.1-BASE.iso软件包中。
507.在master节点安装配置HTTP服务，将软件包XianDian-BigData-v2.1-BASE.iso中的HDP-2.4-BASE和HDP-UTILS-1.1.0.20拷贝到/var/www/html目录中，并启动HTTP服务。
508.查询2个节点的yum源配置文件、JDK版本信息、slaver1节点同步master节点的命令及结果和HTTP服务的运行状态信息，以文本形式提交到答题框。
