ansible-playbook jdk安装

jdk role的目录结构如下：

[root@192 roles]# tree jdk
jdk
├── defaults
├── files
│   └── jdk-8u101-linux-x64.tar.gz
├── handlers
├── meta
├── tasks
│   └── main.yml
├── templates
└── vars└── main.yml

#vars下面的忽略，那是之前写的一个。

task文件内容如下：

[root@192 tasks]# cat main.yml
- name:  copy jdk-8u101-linux-x64.tar.gz remote hostscopy: src=jdk-8u101-linux-x64.tar.gz dest=/usr/local/
- name: tar jdk-8u101-linux-x64.tar.gzshell: chdir=/usr/local tar zxf jdk-8u101-linux-x64.tar.gz
- name: soft linkfile: src=/usr/local/jdk1.8.0_101 dest=/usr/local/java state=link
- name: java_profile configshell: /bin/echo {{ item }} >> /etc/profile && source /etc/profilewith_items:- export JAVA_HOME=/usr/local/java- export JRE_HOME=/usr/local/java/jre- export CLASSPATH=.:\$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:\$JRE_HOME/lib:\$CLASSPATH- export PATH=\$JAVA_HOME/bin:\$PATH

#注意这块有个坑啊,特殊字符一定要反斜杠\ 屏蔽字符的特殊意义，试了好几次才发现这个问题，包括gather_facts 关了也没用，到目标主机就变了，最后发现要\.

#2台机器只跑一台：
