说明： 
files：存放需要同步到异地服务器的源码文件及配置文件； 
handlers：当资源发生变化时需要进行的操作，若没有此目录可以不建或为空； 
meta：角色定义可留空； 
tasks：python安装过程成需要进行的执行的任务； 
templates：用于执行python安装的模板文件，一般为脚本； 
vars：本次安装定义的变量，若无必要可以不建

python3.6.6源码存放目录：
python_install/files/Python-3.6.6.tgz

具体操作
1.创建python角色文件，用于调用python_install
[[email protected]:/etc/ansible]# cat /etc/ansible/python.yml 
---
- hosts: all
  remote_user: root
  roles:
    - python_install

2.创建任务文件
[[email protected]:/etc/ansible/roles]# cat python_install/tasks/copy.yml 
- name: copy python_tgz to client
  copy: src=/etc/ansible/roles/python_install/files/Python-3.6.6.tgz dest=/usr/local/src/
- name: copy install_python_script to client
  copy: src=/etc/ansible/roles/python_install/templates/python_install.sh dest=/tmp/python_install.sh owner=root group=root mode=755

[[email protected]:/etc/ansible/roles]# cat python_install/tasks/install.yml 
- name: install python
  shell: /bin/bash /tmp/python_install.sh

[[email protected]:/etc/ansible/roles]# cat python_install/tasks/main.yml 
- include: copy.yml
- include: install.yml


注意： 
a.copy如果复制目录，需要加上递归参数，recurse； 
b.copy如果复制目录，没有目录将会在目标服务器上创建； 
c.copy如果复制文件到目标服务器的某一个目录下，需要在dest参数上加上/usr/local/src/，而不是/usr/local/src，否则ansible将会把文件复制为src，而不是放在src目录下。 
4.编写模板脚本

[[email protected]:/etc/ansible/roles]# cat python_install/templates/python_install.sh 
#!/bin/bash
# install python3.6.6
# yum tools

yum -y groupinstall "Development tools"
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
cd /usr/local/src
mkdir /usr/local/python3
tar -zxf Python-3.6.6.tgz
cd Python-3.6.6
./configure --prefix=/usr/local/python3
make && make install
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
# end

安装脚本功能： 
1)安装yum依赖包
2)创建目录，解压文件并编译安装到目标目录
3)生成软连接

执行playbook
测试
[[email protected]:/etc/ansible]# ansible-playbook -C python.yml
