將krpano遷移至服務器：ubuntu 16.04 server。
以win的經驗爲基礎，這裏只需解決2個問題：
linux上krpano的安裝與註冊
在linux上，用java執行krpano命令
（1）linux上krpano的安裝與註冊
我以krpano-1.19-pr10爲例，不必無官網下載，在這裏下： http://pan.baidu.com/s/1bppkEbd 上傳到服務器解壓就可以了（裏面有註冊碼）。可是，在生成全景圖時，會有水印，怎麼解決呢？在解壓的文件夾裏，有個叫Serial.txt文件，是一個註冊碼。只需要在服務器註冊這個註冊碼就行了，每個用戶都註冊一遍。
我先把krpano-1.19-pr10上傳到/opt目錄下，unrar 解壓，然後執行krpanotools register命令註冊機器：
root@S189919:/opt/krpano-1.19-pr10# /opt/krpano-1.19-pr10/krpanotools register FXsqTqaGNSZER5dSETEm+VzQEh9sWSa5DZMFsSmMxYV9GcXs8W3R8A/mWXrGNUceXvrihmh28hfRF1ivrW0HMzEychPvNiD8B/4/ZzDaUE9Rh6Ig22aKJGDbja1/kYIqmc/VKfItRE2RTSOIbIroxOtsz626NIpxWksAAifwhpNwuPXqDQpz2sRUMBzoPqZktpkItoSenN2mKd8Klfx7pOuB6CIK3e1CDXgyndqOt2mWybLZcU/wfJVAecfxk15ghiqrzaDsbqrdABDowg==

root@S189919:/opt/krpano-1.19-pr10# exit
exit
wen@S189919:~$ cd /opt/krpano-1.19-pr10/
wen@S189919:/opt/krpano-1.19-pr10$ /opt/krpano-1.19-pr10/krpanotools register FXsqTqaGNSZER5dSETEm+VzQEh9sWSa5DZMFsSmMxYV9GcXs8W3R8A/mWXrGNUceXvrihmh28hfRF1ivrW0HMzEychPvNiD8B/4/ZzDaUE9Rh6Ig22aKJGDbja1/kYIqmc/VKfItRE2RTSOIbIroxOtsz626NIpxWksAAifwhpNwuPXqDQpz2sRUMBzoPqZktpkItoSenN2mKd8Klfx7pOuB6CIK3e1CDXgyndqOt2mWybLZcU/wfJVAecfxk15ghiqrzaDsbqrdABDowg==

這樣，就會在用戶的~/下生成一個.krpanolicense文件
有了krpanolicense，就不用擔心會有水印和版權信息了。
（2）在linux上，用java執行krpano命令
因爲java本身是跨平臺的第一語言，所以選擇java，就等於成功了一半。但在linux上，用java的runtime.exec與在win上的調用命令不同，文件路徑也不同，這是最需要注意的！
以/opt/test/test.jpg的圖片爲例
krpano在linux執行的命令是：
/opt/krpano-1.19-pr10/krpanotools makepano -config=templates/vtour-normal.config /opt/test/test.jpg- 1
而win是：
cmd /c start f:\\krpano\\krpano-1.19-pr10-postable\\krpanotools32.exe makepano -config=\\templates\\vtour-normal.config f:\\test\\test.jpg- 1
linux的文件目錄是”/ “，win是”\\”。
這是完整的krpano工具類：CmdBat

至於如何調用CmdBat類，看具體的業務需求，我是先把全景圖從前臺傳輸到後臺，存在uploadtemp目錄中，再調用krpano處理全景圖，在uploadtemp目錄中生成一個圖片id的文件夾，裏面放vtour，然後把vtour裏面的panos、tour.js、tour.xml、tour.swf 複製到tomcat統一存放全景目錄vshow中，最後再把uploadtemp刪除，頁面只需要去vshow中根據圖片id就可以訪問到每個全景文件。跟在win上的一模一樣。仔細研究CmdBat類，看懂了基本就可以用了，調用時很容易的。如果對java的io不太熟悉，看的吃力，多補補基礎。
vshow：
圖片id文件夾內部：
jsp頁面，把title、圖片id（uploadId ）從後臺傳過來即可：
