salt一键部署hadoop

1.准备工作
 


2.salt关于hadoop的部署脚本，就是上面的init.sls中的内容，至于下面的内容的每一项的意思在之前jdk的脚本中有写。

hadoop-file:
file.managed:
- source: salt://hadoop/hadoop-2.7.3.tar.gz
- name: /opt/hadoop-2.7.3.tar.gz
- user: root
- group: root

hadoop-install:
cmd.run:
- name: 'cd /opt && tar zxf hadoop-2.7.3.tar.gz && ln -s hadoop-2.7.3/ hadoop && chown -R hadoop:hadoop /opt/hadoop*'
- unless: 'test -d /opt/hadoop-2.7.3'
- require:
- file: hadoop-file

hadoop-rmtgz:
file.absent:
- name: /opt/hadoop-2.7.3.tar.gz
- require:
- cmd: hadoop-install

/etc/profile:
file.append:
- text:
- export HADOOP_HOME=/opt/hadoop
- export PATH=$HADOOP_HOME/bin:$PATH
- require:
- file: hadoop-rmtgz

source-profile:
cmd.run:
- name: 'source /etc/profile'
- require:
- file: /etc/profile

3.其余的操作步骤和之前jdk，python类似这里就不写啦。
