關(guān)于樹莓派系列，在有空余的時間里面，我會把斷斷續(xù)續(xù)的工作中處理過的一些小的點記錄一下，比較零散，但是是真實操作記錄，或許對需要的朋友有點小的幫助。
樹莓派系列參見這里：樹莓派系列。
之前有寫過一次遠程更新樹莓派的文章，當(dāng)時腳本在測試環(huán)境調(diào)通了。參見 【樹莓派】【原】遠程連接樹莓派設(shè)備，以及進行遠程應(yīng)用更新與升級
但是在生產(chǎn)環(huán)境測的時候，卻發(fā)現(xiàn)不同環(huán)境還稍微有點小的問題。
因為之前舊的不同版本略有小的差異導(dǎo)致；之后經(jīng)過優(yōu)化，重新測試OK。
優(yōu)化點主要是這兩點，另外有點其他的小調(diào)整：
1.使用ln軟連接方式，而不是mv版本號；
2.修改stop服務(wù)步驟，kill進程有效性；
在這里，重新補充一下最新的Scripts，如下：

腳本使用方法：
1.使用ssh方式登錄agent被控機；
2.執(zhí)行如下命令；
scp boxagent@smith.lifeccp.com:/home/boxagent/boxrelease/script/upgrade_osprey.sh .
3.輸入密碼；
4.等待reboot；
升級完成之后，可以自己查看服務(wù)是否正常，一般情況下，沒什么問題。
