【原因分析】

Cannot assign requested address: bind說明埠衝突，即81埠被佔用，需要修改一下埠。

【解決方法】

找到git配置檔案（我的git檔案為C:\work\git\gitblit-1.8.0\data\defaults.properties）。

解決方法一埠問題：在defaults.properties中找到81埠，如下：

把81埠修改為其他埠，例如91，再啟動gitblit ,即可解決。

解決方法二IP問題：在defaults.properties中找到192.168.0.8，如下：

把192.168.0.8修改為正確的ip地址，再啟動gitblit ,即可解決。
