問題：藍鯨社區版完整部署，執行安裝bkdata時，報“databus.service.consul start failed.”
[root@paas-1 install]# ./bkcec start bkdata

ERROR: init_snapshot_config (databus.tests.DatabusHealthTestCase)
------------------------------------------------------------------------------------------------------------------------------
排查思路：
執行dig databus.service.consul正常
執行./bkcec start bkdata databus提示“ERROR: init_snapshot_config (databus.tests.DatabusHealthTestCase)”
執行./bkcec stop bkdata之後，執行./bkcec install bkdata 1（去除之前的環境，覆蓋安裝）
執行./bkcec initdata bkdata（初始化bkdata）
執行./bkcec start bkdata，再次報“databus.service.consul start failed.”
註釋：cat .bk_install.step可查看安裝進度...
問題解決：重啓了cmdb
原因分析：
bkdata從cmdb獲取基礎業務的信息獲取不到，導致報錯。
還有個是腳本bug
（bkdata機器上，執行vim /data/bkce/bkdata/dataapi/databus/tests.py，將 “update_bizid” 引用這個字段的內容註釋掉，該問題在下個版本中會進行修復。）
tests.py內容註釋掉之後的效果圖示：
其他輔助操作命令：
確認中控機位置：
查看日誌：
[root@paas-1 install]# cat /data/install/.controller_ip
192.168.50.117
[root@paas-1 install]# cd /data/bkce/logs/
[root@paas-1 logs]# ll
加載ssh工具（$：代表變量，cat /data/install/utils.fc）
[root@paas-1 install]# source utils.fc
[root@paas-1 install]# ssh $BKDATA_IP
#ssh登錄主機後，可以執行ifconfig查看對應主機ip，utils.fc爲腳本文件。加載utils.fc主要是爲了調用服務名稱登錄主機。而不需要以ip的方式登錄主機。
[root@rbtnode1 install]# ssh $FTA_IP
查看詳細：
[root@rbtnode1 bkdata]# ls -lsrt

查看啓動任務計劃：確保服務是否正常運行，或看配置文件是否選舉出集羣領導者
如有亂碼，可以執行清除任務計劃，然後[root@rbtnode1 install]# ./bkcec install cron 1進行重新安裝crontab，服務啓動的時候自動會寫入crontab
[root@rbtnode1 ~]# crontab -l

說明：腳本bug的問題主要是爲了解決安裝部署藍鯨時，在初始化bkdata遇到的以下問題：
解決方法：bkdata機器上，執行vim /data/bkce/bkdata/dataapi/databus/tests.py，將 “update_bizid” 引用這個字段的內容註釋掉。
原因分析：如不註釋掉，該引用的字段內容，將消耗很大的主機資源，導致主機因性能瓶頸以致藍鯨服務拉不起來。
