# **Ansible roles 怎么用？** 
# 系统环境
os: `Centos 6.7 X64`
python: `2.6.6`
# 安装ansible和git
```bash
[root@node ~]# yum install -y ansible git
[root@node ~]# ansible --version
ansible 2.2.1.0
config file = /etc/ansible/ansible.cfg
configured module search path = Default w/o overrides
```
## 设置ansible
关闭主机ssh known_hosts检查
配置文件：/etc/ansible/ansible.cfg
```vim
59 host_key_checking = False
```
## 使用git 克隆ansible role
```bash
[root@node roles]# git clone https://github.com/lework/Ansible-roles.git /etc/ansible/roles/

```
## 添加主机清单
这里以192.168.77.130主机为例，并将其设为node2组内。
```
#/etc/ansible/hosts
[node2]
192.168.77.130 ansible_ssh_pass=123456
```
## 查看role的README.md文档
```
# Ansible Role: python2.7
Centos 6.7版本中的python2.6升级到2.7
## 要求
此角色仅在RHEL及其衍生产品上运行。
## 测试环境
ansible `2.2.1.0`
os `Centos 6.7 X64`
## 角色变量
software_files_path: "/opt/software/"
software_install_path: "/usr/local"
python_version: "2.7.13"
python_file: "Python-{{ python_version }}.tgz"
python_file_path: "{{ software_files_path }}/{{ python_file }}"
python_file_url: "http://www.python.org/ftp/python/{{ python_version }}/Python-{{ python_version }}.tgz"
pip_source_url: "https://pypi.tuna.tsinghua.edu.cn/simple"
change_pip_source: true
## 依赖
没有
## github地址
https://github.com/lework/Ansible-roles/tree/master/python2.7
## Example Playbook
- hosts: servers
roles:
- python2.7
- hosts: server
roles:
- { role: python2.7, python_version: "2.7.13"}
```
- 上诉说明了此role在哪个环境下正常运行，其他环境暂不保证运行成功。
- 可以自定义角色变量，达到自己想要的结果。比如想要安装python2.7.12的版本，可以在playbook中定义`python_version: "2.7.12"`,就可以安装2.7.12版本的python了。
- 如果文章中有依赖，必须先安装依赖，才能运行此role。
- 在编写Playbook时也可以参考上列的Playbook例子。
## 编写playbook
这里以python2.7角色为例，将为node2组内的所有主机安装python2.7服务。
查看[Ansible Role系统环境 之【python2.7】](http://www.jianshu.com/p/2b38b943a177) 使用帮助，根据自身情况设置相应的变量，这里设置python的版本为2.7.14。
文件路径：/etc/ansible/roles/python2.7.yml
```yml
---
- hosts: node2
roles:
- { role: python2.7, python_version: "2.7.14"}
```
## 执行playbook
```bash
[root@node ansible]# ansible-playbook python2.7.yml

## 查看主机是否安装了python2.7版本
使用ad-hoc方式查看
```bash
[root@node ansible]# ansible node2 -m shell -a 'python -V'
192.168.77.130 | SUCCESS | rc=0 >>
Python 2.7.12
```
在主机上查看
```bash
[root@node2 ~]# python -V
Python 2.7.12
```
