2>.关闭防火墙
[root@node101.yinzhengjie.org.cn ~]# systemctl stop firewalld

3>.配置本机的免密登录（如果不做这步的话，在启动hdfs集群时会报权限被拒绝的错误）
[root@node101.yinzhengjie.org.cn ~]# ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
Generating public/private rsa key pair.
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:

4>.安装jdk
大家可以自行去Oracle官网下载相应的jdk，我这里给出下载地址：https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html（推荐下载tar.gz的安装包，解压后配置环境变量即可使用）。
[root@node101.yinzhengjie.org.cn ~]# tail - /etc/profile
#ADD JAVA_PATH
JAVA_HOME=/yinzhengjie/softwares/jdk

[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# which java

二.安装ansible软件
1>.查看yum源，我们此处默认你的服务器是可以联网
[root@node101.yinzhengjie.org.cn ~]# yum repolist

[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# yum repolist
2>. 查看当前的yum支持的ansible版本
[root@node101.yinzhengjie.org.cn ~/Downloads]# yum info ansible

Description :
: Ansible is a radically simple model-driven configuration management,
: multi-node deployment, and remote task execution system. Ansible works
: over SSH and does not require any software or daemons to be installed
: on remote nodes. Extension modules can be written in any language and
: are transferred to managed machines automatically. [root@node101.yinzhengjie.org.cn ~/Downloads]#
[root@node101.yinzhengjie.org.cn ~/Downloads]# yum info ansible
3>.安装ansible
[root@node101.yinzhengjie.org.cn ~/Downloads]# yum -y install ansible
