Ansible 安装jdk

1. 在hosts文件添一个group，里面是你需要安装jdk的ip，如：

[newhosts]
192.168.2.155 ansible_ssh_user=hadoop ansible_ssh_pass=hadoop ansible_sudo_pass=hadoop
192.168.2.159 ansible_ssh_user=hadoop ansible_ssh_pass=hadoop ansible_sudo_pass=hadoop

2. 创建层级结构

├── roles
├── jdk-install
│ ├── default
│ ├── files #jdk压缩包存放目录
│ │ └── jdk-7u79-linux-x64.tar.gz 
│ ├── handler
│ ├── meta
│ ├── tasks #部署安装流程yml文件目录
│ │ └── main.yml 
│ ├── templates
│ │ └── set_jdk.sh #配置目标机器的Java环境变量脚本
│ └── vars
│    └── main.yml #记录使用到的变量
├──jdk-install.yml
├──hosts
├──jdk-install.sh

3. 编辑tasks下面的main.yml

- name: copy jdk to remote host
  copy: src=jdk-7u80-linux-i586.tar.gz dest=~
- name: unzip jdk
  shell: tar -zxf jdk-7u80-linux-i586.tar.gz
- name: creat soft link
  shell: ln -s ~/jdk1.7.0_80 jdk
- name: set jdk_env copy use template
  template: src=set_jdk.sh dest=~/set_jdk.sh
- name: execute script to set jdkenv
  shell: sh set_jdk.sh
- name: source bash_profile
  shell: source ~/.bash_profile
- name: remove files
  shell: rm jdk-7u80-linux-i586.tar.gz set_jdk.sh

4. 编辑templates下面的set_jdk.sh

#!/bin/bash

echo "export JAVA_HOME=${HOME}/jdk" >> ~/.bash_profile
echo 'export CLASSPATH=.:${JAVA_HOME}/lib' >> ~/.bash_profile
echo 'export PATH=${JAVA_HOME}/bin:$PATH' >> ~/.bash_profile
source ~/.bash_profile

5. 将使用到的变量编辑在vars下的main.yml

user: hadoop
host_cluster: newhosts

6. jdk-install.yml

- hosts: "{{ host_cluster }}"
  gather_facts: no
  vars:
    user: "{{ user }}"
  roles:
    - jdk

7. ansible-playbook安装

[hadoop@Ansible1 ansible]$ ansible-playbook jdk-install.yml
