還處在基礎學習過程，寫這篇文章也是壯着膽子來寫的，因爲好多的基礎知識還不太明白（鳥哥的那本私房菜都還沒學完呢呵呵），正好趕上有同事需要搭一個環境在上邊開發，既然有需求了那就試試吧，下邊就把部署過程中遇到的問題記錄下來，以備以後可能還會遇到相同的問題知道怎麼解決了。
言歸正傳，本來也是學習爲主，好多還處於一知半解當中就找了一個Packstack 自動化部署工具，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
執行上邊操作過程如果一切順利大概需要40分鐘吧（預估），遇到的問題就在packstack --allinone部署時出現的：
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
這個錯誤困擾了半天，網上查一些資料說是主機名的問題，好休息/etc/hosts：
127.0.0.1 localhost ops 10.10.15.14 ops
保存後再去執行
# packstack --allinone
此時出現第二個問題，這個問題是第二天出現的：
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
知識儲備不夠還是解決不了，上網找資料吧度娘不給力還是谷歌靠譜，有說需要再次運行yum update直到沒有軟件需要更新就可以了，接着試運行更新命令確實有一個軟件更新了，但感覺應該對部署影響不大，繼續執行：
# packstack --allinone
沒想到還真順利過去了，具體是什麼原因還是沒搞懂，只不過高興沒一會第三個問題接踵而至：
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
不碰真東西是真不到自己掌握的知識是多麼的匱乏，一個都解決不了，接着google，文章裏說需要將
NetworkManager停掉，還有防火牆以及SELinux，好吧，接着試：
# systemctl list-unit-files |grep NeworkManager NetworkManager-dispatcher.service disabled NetworkManager-wait-online.service disabled NetworkManager.service disabled # systemctl disable NetworkManager #setenforce 0
一切都關閉妥當，繼續packstack --allinone

successfully ！！這回可以小激動一下了，試試吧！
總算是可以登錄了，不過配置可能不太對，現在8個G的內存外加5G的交換分區全部被佔滿了，導致後邊開網頁敲代碼都卡的不行，等明天再好好研究研究吧。
也算是邁出了第一步，繼續加油！
