• 在 jekyll 用户下运行
• gem jekyll 安装好
• 安装好 rouge gem install kramdown rouge

$ gem -v
3.0.8

$ jekyll -v
jekyll 4.2.0

创建站点 myblog

执行命令 jekyll new myblog，新建站点 myblog

$ jekyll new myblog

查看myblog文件

$ ls myblog/
404.html    Gemfile     _config.yml _posts      about.markdown  index.markdown

安装主题 themes

配置Gemfile，追加如下内容：

# Gem install themes
gem "minimal-mistakes-jekyll"
gem "just-the-docs"
gem "jekyll-theme-simplex"

这样，我们就有4个主题：minima(default)、minimal-mistakes-jekyll、just-the-docs、jekyll-theme-simplex

以root用户执行命令bundle，获取/升级 gems

root@VM-0-8-freebsd:/usr/home/jekyll/myblog # bundle

Bundle complete! 9 Gemfile dependencies, 52 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.

通过gem list --local可以查看到刚才安装主题的gem包。

通过bundle info --path $theme_name查看安装的主题，可以看到都安装在/usr/local/lib/ruby/gems/2.7/gems/目录下，与CentOS不同。如下：

$ bundle info --path minima
/usr/local/lib/ruby/gems/2.7/gems/minima-2.5.1
$ bundle info --path minimal-mistakes-jekyll
/usr/local/lib/ruby/gems/2.7/gems/minimal-mistakes-jekyll-4.24.0
$ bundle info --path just-the-docs
/usr/local/lib/ruby/gems/2.7/gems/just-the-docs-0.3.3
$ bundle info --path jekyll-theme-simplex
/usr/local/lib/ruby/gems/2.7/gems/jekyll-theme-simplex-0.9.8.15

配置使用主题

配置 _config.yml

# Build settings
#theme: minima
theme: minimal-mistakes-jekyll 
#theme: just-the-docs
#theme: jekyll-theme-simplex

更新主题
以 jekyll 用户执行 bundle update

$ bundle update

... 省略 ...
Using jekyll-theme-simplex 0.9.8.15
Using just-the-docs 0.3.3
Using minima 2.5.1
Using minimal-mistakes-jekyll 4.24.0
Bundle updated!

配置监听端口

配置 _config.yml，增加如下：

# Serving
host: 0.0.0.0

配置markdown

安装 rouge

gem install kramdown rouge

配置_config.yml

markdown: kramdown
highlighter: rouge

kramdown:
  input: GFM
  syntax_highlighter: rouge

rouge创建css文件，在当前站点目录下

mkdir -p assets/css/

rougify style thankful_eyes > assets/css/syntax.css

修改index.markdown，指定引用layout；创建被指定引用的layout，指定引用includes/markdown.html；创建_includes/markdonw.html ， 引用rouge创建的css文件

mkdir _layouts
mkdir _includes

启动jekyll

• jekyll build 编译，并将静态文件输出到 _site 目录

$ jekyll build
Configuration file: /usr/home/jekyll/myblog/_config.yml
            Source: /usr/home/jekyll/myblog
       Destination: /usr/home/jekyll/myblog/_site

                    done in 1.123 seconds.
 Auto-regeneration: disabled. Use --watch to enable.

• 在myblog目录，执行启动命令 nohup bundle exec jekyll serve --livereload &，如下：

$ nohup bundle exec jekyll serve  --livereload &
$ appending output to nohup.out

$ ls
404.html    Gemfile     Gemfile.lock    _config.yml _posts      _site       about.markdown  index.markdown  nohup.out

• 检查端口，运行于本地的4000，35729端口
