Ansible + shell 实现部署fastdfs+nginx 实现图片服务器并提供动态缩放功能；

因为公司阿里服务器变动几次，手动部署了好几次fastdfs+nginx，于是就想到了自动化部署，以下为脚本内容，由于只是想把着功能实现，并未有完完整的判断逻辑；

以下为ansible-playbook及shell及模板nginx-fastdfs及动态缩略图配置;

如有错误，请不吝赐教；

最后安装完成以后，并未启动fastdfs ,请先运行命令启动fastdfs: fdfs_trackerd /etc/fdfs/tracker.conf && fdfs_storaged /etc/fdfs/storage.conf

启动完成以后，如果不能正常访问返回415，请复制粘贴模板内容到nginx的配置文件里；
