lnvamp的意思是Linux（centos7.2），Nginx，varnish，Apache，MySQL，PHP。我在这个平台之上构建的discuz论坛，我写了一个roles来实现，这个脚本很不健壮幂等性不足，需要大量的判断继续完善，由于时间原因我就不继续完善了，先把草稿贴出来。同时这个脚本的复用性也不好，基本上没有使用变量，后期会慢慢改善。
架构图如下
nginx提供反向代理，安装nginx
varnish提供缓存，安装varnish
server提供页面处理，安装httpd,php,php-mysql,nfs-utils
file提供数据库和网页文件，安装mysql-server,mysql-python,nfs-utils
file的ansible内容写法
注意
因为手头没有主机了，这里file主机我使用的是centos6
mysql-python没有对应的rpm包，由于考虑幂等性的原因这里我没有使用ansible来完成，我在宿主机上执行的，这里我们只好手动编译，手动编译脚本如下
yum install python-devel mysql-devel zlib-devel openssl-devel -y yum groupinstall development tools -y wget https://pypi.python.org/packages/9a/81/924d6799494cf7fb24370335c2f782088d6ac4f79e4137d4df94cea3582c/MySQL-python-1.2.3.tar.gz tar xf MySQL-python-1.2.3.tar.gz cd MySQL-python-1.2.3 python setup.py install

这个实验基本上没有说原理和操作步骤，只是简单罗列文件，最后我把我编写的完整roles的下载路径http://down.51cto.com/data/2286987
