50Mb push 警告
remote: warning: Large files detected.
# remote: warning: File big_file is 55.00 MB; this is larger than GitHub's recommended maximum file size of 50 MB
100Mb push 限制
remote: warning: Large files detected.
# remote: error: File giant_file is 123.00 MB; this exceeds GitHub's file size limit of 100 MB
解决方案如下：
1、需要在服务器上用git filter-branch --tree-filter 'rm -f 文件名' HEAD把文件彻底从库中删除
如: git filter-branch --tree-filter 'rm -f app.rar' HEAD
2、移除大文件，注意备份
$git rm --cached giant_file
# Stage our giant file for removal, but leave it on disk
$git commit --amend -CHEAD
# Amend the previous commit with your change
# Simply making a new commit won't work, as you need
# to remove the file from the unpushed history as well
$git push
# Push our rewritten, smaller commit
