本腳本用于游戲服務(wù)器端的自動更新，主要流程就是把更新包和腳本的配置文件放在一個中心端center，分支機(jī)房client去中心端center下載更新包，并驗(yàn)證MD5坑资，分支機(jī)房的游戲服務(wù)器根據(jù)自身需求通過rsync下載相應(yīng)的更新包，游戲服務(wù)器通過解壓朋譬、拷貝盐茎、驗(yàn)證部分重要文件的MD5來確保更新正確完成兴垦，目前此腳本已經(jīng)用于更新本公司多款游戲徙赢，兼容windows、linux系統(tǒng)（根據(jù)自身需要更改相關(guān)路徑）探越，可以用頁面去調(diào)用狡赐，已經(jīng)寫了post頁面返回值。
