+# tx2_update_faster
+
+  此工具基于ansible批量操作工具，利用FTP在传输升级包时去中心化，采用仿P2P方式提高整体传输速度，理论上升级包越大、节点越多速度提高越大。
+请将此压缩包放在/home/ubuntu下解压进入解压后目录，使用方法：
+
+```shell
+1.  升级包传至当前目录；
+2.  chmod +x tx2_update_faster.sh
+    ./tx2_update_faster.sh IP组 升级包名称
+    例：
+      ./tx2_update_faster.sh tx2 VAServer_LINUX-ARM-TX2_r78250-20200804-liuh.tar.gz
+```
