学习OpenStack Mitaka单节点部署笔记

还处在基础学习过程，写这篇文章也是壮着胆子来写的，因为好多的基础知识还不太明白（鸟哥的那本私房菜都还没学完呢呵呵），正好赶上有同事需要搭一个环境在上边开发，既然有需求了那就试试吧，下边就把部署过程中遇到的问题记录下来，以备以后可能还会遇到相同的问题知道怎么解决了。
言归正传，本来也是学习为主，好多还处于一知半解当中就找了一个Packstack 自动化部署工具，下面所有的操作配置都是用它完成。

# yum install -y centos-release-openstack-mitaka
# yum update -y
# sudo yum install -y openstack-packstack
# packstack --allinone

执行上边操作过程如果一切顺利大概需要40分钟吧（预估），遇到的问题就在packstack --allinone部署时出现的：1.

PuppetError: Error appeared during Puppet run: 10.10.15.14_amqp.pp
Error: Execution of '/usr/bin/yum -d 0 -e 0 -y install erlang' returned 1: Error downloading packages:
You will find full trace in log /var/tmp/packstack/20160518-220204-u2bfTF/manifests/10.10.15.14_amqp.pp.log

这个错误困扰了半天，网上查一些资料说是主机名的问题，好休息/etc/hosts：

127.0.0.1   localhost ops
10.10.15.14 ops

保存后再去执行

# packstack  --allinone

此时出现第二个问题，这个问题是第二天出现的：2.

PuppetError: Error appeared during Puppet run: 10.10.15.14_horizon.pp
Error: Execution of '/usr/bin/yum -d 0 -e 0 -y install openstack-dashboard' returned 1: Error downloading packages:
You will find full trace in log /var/tmp/packstack/20160519-142443-mES6ez/manifests/10.10.15.14_horizon.pp.log

知识储备不够还是解决不了，上网找资料吧度娘不给力还是谷歌靠谱，有说需要再次运行yum update直到没有软件需要更新就可以了，接着试运行更新命令确实有一个软件更新了，但感觉应该对部署影响不大，继续执行：

# packstack  --allinone

没想到还真顺利过去了，具体是什么原因还是没搞懂，只不过高兴没一会第三个问题接踵而至：3.

ERROR : Error appeared during Puppet run: 10.10.15.14_gnocchi.pp
Error: Execution of '/usr/bin/yum -d 0 -e 0 -y install openstack-gnocchi-metricd' returned 1: Error downloading packages:
You will find full trace in log /var/tmp/packstack/20160519-160900-aneTEN/manifests/10.10.15.14_gnocchi.pp.log

不碰真东西是真不到自己掌握的知识是多么的匮乏，一个都解决不了，接着google，文章里说需要将NetworkManager停掉，还有防火墙以及SELinux，好吧，接着试：

# systemctl list-unit-files |grep NeworkManager
NetworkManager-dispatcher.service             disabled
NetworkManager-wait-online.service            disabled
NetworkManager.service                        disabled
# systemctl disable NetworkManager
#setenforce 0

一切都关闭妥当，继续packstack --allinone

successfully ！！这回可以小激动一下了，试试吧！










总算是可以登录了，不过配置可能不太对，现在8个G的内存外加5G的交换分区全部被占满了，导致后边开网页敲代码都卡的不行，等明天再好好研究研究吧。

也算是迈出了第一步，继续加油！
