Fuel7.0安装

陈沙克在他的经典文章里分析了多个安装部署工具，用于openstack部署。

当然时代变了，所以很多这些工具都改头换面了。

目前看，

1 Mirantis Fuel仍然是最好的商业用选择，虽然还有瑕疵。

fuel在7和7之后已经提供开源的plugin插件，例如contrail的插件。并将fuel plugin方案放入openstack发展会中。

fuel在6的时候已经在提供商业化的plugin了。

fuel目前的8有个讨厌的地方就是需要联网取些内容（是我网的问题，联网去取docker image供slave用），对centos7.0的版本兼容性也不好。（是centos7.0的问题，其升kernel到7.1很大可能会挂）

fuel的瑕疵主要是有些场景会莫名的出现异常，部分删除和增加云会导致异常，一些硬盘大小识别在安装快结束时才告诉你容量不足。（主要是6的问题，8因网络问题至今无感）

2 RDO，即原来的packstack

RDO无光盘，也是出了名的网络安装，没网怎么活？

RDO安装的粒度必须是全openstack

RDO安装了ceilemeter，第二次换了ip（如果是dhcp申请的），重装，如果不选择ceilemeter，则原来的ceil不会自动消亡，还在那里盲目发信息要求通讯。

3 其他puppet类，如陈所言。

其中rackspace，我没找到光盘，也没找到脚本。rackspace是不是已经不怎么玩openstack了？

4 ansible和kolla

ansible比较方便，因为总有人讨厌puppet，在下不懂puppet，所以也不愿意碰

kolla是ansible语言的上层开发。提供了以openstack 服务级粒度的openstack安装部署。

kolla可以支持对失败的openstack的nova，keystone服务重新单独部署。

kolla还基于docker

fuel7.0安装，和fuel5.0、6安装相似，这次小弟是在virtualbox上安装的。

小弟修改了config.sh

主要改动点

1 master， 1compute, 1controller,

给计算节点多点资源。

不过安装成功后，惊讶的发现fuel7很智能的把整张盘的大小都给了compute，controller

内存上各节点的配置则和config.sh相同。

贴上config.sh
