Ansible（二）、实现JDK批量安装

1.准备软件包

[root@node1 soft]# ll
total 195094741
-rw-r--r-- 1 root root 195094741 Jul  6 00:09 jdk-8u221-linux-x64.tar.gz

2.hosts文件配置

/etc/ansible/hosts

[jdk]
172.17.16.4
172.17.16.12
172.17.16.13

3.编写yaml

环境变量写入/etc/bashrc，是为了其他依赖应用执行时找到JAVA_HOME，原因如下：

• login shell加载环境变量的顺序是：① /etc/profile ② ~/.bash_profile ③ ~/.bashrc ④ /etc/bashrc
• non-login shell加载环境变量的顺序是： ① ~/.bashrc ② /etc/bashrc

- hosts: jdk
  remote_user: root
  vars:
      name: "jdk"
      install_path: /data/cloud1
  tasks:
    - name: "1.初始化工作目录"
      shell: mkdir -p {{install_path}}/jdk
    - name: "2.拷贝安装包"
      copy: src=/data/soft/jdk-8u221-linux-x64.tar.gz dest={{install_path}}/jdk.tar.gz
    - name: "3.解压安装包"
      shell: tar -zxvf {{install_path}}/jdk.tar.gz -C {{install_path}}/jdk  --strip-components 1
    - name: "4.添加环境变量"
      shell: echo 'export JAVA_HOME={{install_path}}/jdk' >> /etc/profile &&
             echo 'export PATH=$PATH:$JAVA_HOME/bin' >> /etc/profile &&
             source /etc/profile &&
             echo 'export JAVA_HOME={{install_path}}/jdk' >> /etc/bashrc &&
             echo 'export PATH=$PATH:$JAVA_HOME/bin' >>   /etc/bashrc &&
             source /etc/bashrc
    - name: "5.清理安装文件"
      shell: rm -rf {{install_path}}/jdk.tar.gz

4.执行

[root@node1 yaml]# ansible-playbook jdk.yaml 
[DEPRECATION WARNING]: The TRANSFORM_INVALID_GROUP_CHARS settings is set to allow bad characters 
in group names by default, this will change, but still be user configurable on deprecation. This 
feature will be removed in version 2.10. Deprecation warnings can be disabled by setting 
deprecation_warnings=False in ansible.cfg.
 [WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see
details

 [WARNING]: Found variable using reserved name: name
