Github提交密码信息后补救措施

新建一个repo，在添加.gitignore文件之前，把仓库push到github，虽然数据库密码配置文件可以删除，但是git的commit记录依旧在。根据github官方的建议，可以使用bfg来删除commit记录

使用BFG工具

BFG Repo-Cleaner是github官方推荐的工具，用于删除敏感信息数据文件

• 删除敏感信息文件

  config.ini是MySQL数据的链接配置文件，前面已经提交过一次。此时使用BFG工具进行删除

java -jar .\bfg-1.14.0.jar --delete-files config.ini

• 强制push

  删除文件后，必须push只github仓库 我使用的是Pycharm，强制push，需要在push对话框，选择Force push

git push --force

• 提示：

  如果在pycharm中无法选中Force push，需要进行配置： File-->Settings-->Version Control-->Git-->Push-->Protected branches，删除文本框中的master,main
