首先從最簡單的開始，新建一個虛擬機（Launch Instance）並查看其日誌
1.在網頁上登錄搭建好的openstack虛機（名稱爲op1）的dashboard界面
2.遠程SSH登錄op1的命令行界面
Xshell輸入
ssh 192.168.xx.xx
ssh 後面是你的服務器域名(需要登錄一個控制節點，一個計算節點，因爲創建虛機的日誌有些在控制節點上，有的在計算節點上)
登錄完成是這樣的：
3.在瀏覽器界面選擇新建虛擬機（填好名稱、選好鏡像、網絡），點擊新建（不管成功與否）。
然後在命令行執行tail /opt/stack/logs/nova-api.log查看控制節點nova-api的日誌
tail /opt/stack/logs/nova-api.log
非devstack自動化部署的日誌不在stack底下，在/var/log/模塊名/ 這個目錄下，比如nova
然後可以tail打開日誌，內存大的話也可以直接vim打開（shift+G直接跳到最後）
查看流程如上，然後我們來解決一下查看的實操中的一些問題
1.各個日誌大概是幹嘛的
- nova-compute.log：虛擬機實例在啓動和運行中產生的日誌
- nova-network.log：關於網絡狀態、分配、路由和安全組的日誌
- nova-manage.log：運行nova-manage命令時產生的日誌
- nova-scheduler.log：有關調度的，分配任務給節點以及消息隊列的相關日誌
- nova-objectstore.log：鏡像相關的日誌
- nova-api.log：用戶與OpenStack交互以及OpenStack組件間交互的消息相關日誌
- nova-cert.log：nova-cert過程的相關日誌
- nova-console.log：關於nova-console的VNC服務的詳細信息
- nova-consoleauth.log：關於nova-console服務的驗證細節
- nova-dhcpbridge.log：與dhckbridge服務先關的網絡信息
2.日誌一大堆，怎麼獲取到當前請求的的日誌
打開圖形界面，選建的虛擬機點進去，會有一個虛擬機ID，可以根據這個全局定位
複製好這個ID，然後在命令行打開任意一個日誌文件（建議使用vim打開或者grep命令直接重定向導出成文件，這樣 便於搜索）
//如下是用vim打開，然後輸入？和ID，按enter鍵進行搜索的示例
結果如圖
然後我們獲取到req ID，就可以用req ID搜索，更好的搜索此條請求的日誌
方案一：
cat /var/log/nova/nova-compute.log|grep req-138eaddd-4792-45b2-af9c-313fa4e363cb
這樣會打印出nova-compute.log中所有包含此ID的日誌，並且將ID標紅顯示
方案二：
在xhell裏面查看日誌不方便看，可以重定向到一個新建的文件中，然後拖出來看（下面的栗子是將查詢到的id爲req-09a61c6f-c4bb-4fbe-a4f8-33bcd12bf21c的日誌保存到/home/test文件中）
grep -rn 'req-09a61c6f-c4bb-4fbe-a4f8-33bcd12bf21c' nova-compute.log > /home/test
然後將home/test的直接複製到windows本機用本地任意編輯器打開進行分析
3.除了dashboard界面，用命令行怎麼建立虛擬機
openStack的發行版更新實在太快了，網上有很多帖子教怎麼用命令行進行一些openstack操作，但是就我自己實踐而言，好多命令都過時失效openstack不再支持了，但是不方，官網文檔你值得擁有https://docs.openstack.org/queens/index.html
//記得切換到自己用的openstack版本（我用的Queens版本），不然默認是最新tiain版本
然後照着文檔搞吧（以前老命令是nova list 現在換爲 openstack list，部分仍舊兼容比如nova favlor-list）
如果無法識別nova命令，出現這種問題：
這是因爲沒有加載環境變量，添加上resource資源就好了(本質是把source配置到環境變量中，就像java配置jdk的環境變量一樣)
source /root/adminrc
再執行nova flavor-list
另外，也可以用pcs resource可以查看各種服務是否開啓
pcs resource
最後我們在任意一個編輯器裏查看我們之前重定向出來的日誌文件，定位出現的問題
本次示例GUI提示的問題描述如圖：
然後進行日誌分析
