书接上文 （虽然我是先写的这一篇），当我们有了一个可用的hugo目录后，就可以把它部署到github等静态网页托管服务了。如果你的强迫症不是很严重的话，可以把/public目录直接push到新的repo里；不过如果为了得到一个整洁的主页，可以用同一个repo的master分支保存源文件，gh-page分支来展示，像这里说的那样。
这里假设你已经init过了你的hugo目录：
# Create a new orphand branch (no commit history) named gh-pages
git checkout --orphan gh-pages
# Unstage all files
git rm --cached $(git ls-files)
# Grab one file from the master branch so we can make a commit
git checkout master README.md
# Add and commit that file
git add .
git commit -m "INIT: initial commit on gh-pages branch"
# Push to remote gh-pages branch
git push origin gh-pages
# Return to master branch
git checkout master
# Remove the public folder to make room for the gh-pages subtree
rm -rf public
# Add the gh-pages branch of the repository. It will look like a folder named public
git subtree add --prefix=public <你的.git地址> gh-pages --squash
# Pull down the file we just committed. This helps avoid merge conflicts
# 这里我先push了一次，否则会出现fatal: refusing to merge unrelated histories
# 好像是git的bug
git subtree push --prefix=public <你的.git地址> gh-pages
git subtree pull --prefix=public <你的.git地址> gh-pages
hugo
# Add everything
git add -A
# Commit and push to master
git commit -m "Updating site" && git push origin master
# Push the public subtree to the gh-pages branch
git subtree push --prefix=public <你的.git地址> gh-pages
之后每次更新需要
hugo
git add -A
git commit -m "some messages"
git push origin master
git subtree push --prefix=public <你的.git地址> gh-pages
像我这样的强迫症可以把主题也做一个subtree出来。
