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！
