只需告诉git假设该文件未更改：
$ git update-index --assume-unchanged FILE [FILE ...]
来自手册：
--assume-unchanged, --no-assume-unchanged
When these flags are specified, the object names recorded for the paths are not updated. Instead, these options set and unset the "assume unchanged" bit for the paths. When the "assume unchanged" bit is on, git stops checking the
working tree files for possible modifications, so you need to manually unset the bit to tell git when you change the working tree file. This is sometimes helpful when working with a big project on a filesystem that has very slow
lstat(2) system call (e.g. cifs).
This option can be also used as a coarse file-level mechanism to ignore uncommitted changes in tracked files (akin to what .gitignore does for untracked files). Git will fail (gracefully) in case it needs to modify this file in the
index e.g. when merging in a commit; thus, in case the assumed-untracked file is changed upstream, you will need to handle the situation manually.
您可以使用smudge/clean过程（一种gitattribute过滤器驱动程序，在ProGit中描述）
.htaccess内容，以使其适用于当前环境。基于Git的方法：使用一个生产分支，并将特定于生产环境的更改保留在其中。要发布到生产环境，请将您的主分支合并到生产分支。
基于部署的方法：使用工具（如Capistrano / CFEngine / ...）自动化部署过程。这有许多优点，其中之一是能够将配置与代码分开。
