Git: There is no tracking information for the current branch.

在执行git pull的时候，提示当前branch没有跟踪信息：

1
2
3
git pull
There is no tracking information for the current branch.
Please specify which branch you want to merge with.

  对于这种情况有两种解决办法，就比如说要操作master吧，一种是直接指定远程master：

1
git pull origin master

  另外一种方法就是先指定本地master到远程的master，然后再去pull：

1
2
git branch --set-upstream-to=origin/master master
git pull

  这样就不会再出现“There is no tracking information for the current branch”这样的提示了。 ———————————————— 版权声明：本文为CSDN博主「K.Sun」的原创文章，遵循CC 4.0 BY-SA版权协议，转载请附上原文出处链接及本声明。 原文链接：https://blog.csdn.net/sinat_36246371/article/details/79738782

宝塔面板如何卸载

宝塔面板如何卸载？宝塔面板是国内一款简洁易用的服务器管理面板，而有时候我们出于各种各样的原因可能需要卸载宝塔。面板既然能够安装，当然也可以卸载，下面我们介绍下卸载方法。 windows面板卸载 1.打开宝塔面板windows版安装目录，路径为：面板安装数据盘:\BtSoft\ServerAdmin 2.运行 UnInstall.exe 开始面板卸载 3.最后使用注册表清理软件或者360清理，清理注册表才可以清除服务文件。在卸载完成后，重启服务器以确保卸载干净。 linux面板卸载方法 一、脚本卸载 1.你需要先在面板中将通过面板安装的所有软件卸载，如 nginx、mysql、php 等等，然后，进入 SSH 命令行，输入以下命令： /etc/init.d/bt stop && rm -f /etc/init.d/bt && rm -rf /www/server/panel 2.或者脚本卸载更暴力一点的直接是都卸载，命令如下：

1
2
wget http://download.bt.cn/install/bt-uninstall.sh
sh bt-uninstall.sh

  二、后续解决 虽然卸载了面板及面板环境，可是系统还是会残留一些文件，比如 www 目录，网站文件。为防止安装别的面时出现一些错误，我们可以用命令：rm –rf www 强制删除 www 文件夹。 以上是关于宝塔面板如何卸载的介绍，安装宝塔面板需要确保纯净系统安装，西部数码云服务器提供预装好宝塔面板的系统模板，可直接安装使用，如需安装请点击 https://www.west.cn/cloudhost/linux.asp   from:https://www.west.cn/docs/58109.html
