使用gitbook快速搭建文档中心

背景

在研发一个系统,主要给公司内部同事用,按理说,简单点的话,搞个使用文档就行了,但产品经理希望是做成一个文档中心,比如,你学习个新技术的时候,比如vue,一般有个在线的帮助文档,他的想法就是这种。

我们就开始了调研,刚开始看了下wordpress(好多云服务器支持用这个来搭建网站),后面发现好复杂,我们只需要一个清爽的帮助文档而已;后面发现文档中心这种,主要分两类,一类是动态的,有数据库,有后台管理界面,可以在后台管理中去发布文档;一种是静态的,基本就是提供写好的markdown,然后部署到服务器上,用特定技术预先渲染成html,再利用nginx之类的指向这些html,一个静态文档中心就有了。

前一阵调研了一个叫gitbook的,属于静态方案,这里简单记录下搭建过程。

gitbook 简介

gitbook的官网是https://www.gitbook.com/,它官网主要是商业版本,就是个在线网站,你可以在里面写文档,体验还可以;

开源版本维护在github,https://github.com/GitbookIO/gitbook,文档也是在github维护:

https://github.com/GitbookIO/gitbook/blob/master/docs/setup.md

目前,开源版本的发布包,最近一个版本是2018年10月,因为团队都去搞商业版本去了,这边就没维护了。

但是,gitbook做出来效果还可以,它也支持很多插件,由于gitbook是node开发的,所以插件就是各种npm包:

插件可以在npm官网查找,gitbook的插件都是有规范的,是gitbook-plugin-开头:

gitbook做出来的网站的效果

示例1

https://handbook.enspiral.com/guides/blogging

image-20231021161050857

该网站的搜索效果是做不出来的,这个是对接了专门的搜索网站

对应的github:https://github.com/enspiral/handbook

示例2

https://tutorial.djangogirls.org/

github:https://github.com/DjangoGirls/tutorial

开源版本可以做到的搜索的效果:

示例3

这边是一个中文站:

大体效果就上面那些,如果觉得还可以,就可以看看怎么搭建了。

gitbook的fork版本

gitbook的开源版本没怎么维护了,但是后面社区又有人接着维护,那就是honkit

📖 HonKit is building beautiful books using Markdown - Fork of GitBook

这个到现在也还在维护,但是感觉搭建出来效果差不多,不知道优化了哪里,不过反正honkit也是支持那些老的gitbook的插件,可以考虑直接用honkit搭建。

安装过程

centos7.9 node安装

我之前搭建过一次,就是遇到一些小问题,所以降了版本,一路降到了node的v12:

https://nodejs.org/download/release/v12.3.0/

下载压缩包,解压,然后设置到/etc/profile

代码语言:javascript
复制
vim /etc/profile
export PATH=/root/upload/node-v12.3.0-linux-x64/bin:$PATH
代码语言:javascript
复制
[root@VM-0-6-centos ~]# node -v
v12.3.0
[root@VM-0-6-centos ~]# npm -v
6.9.0

本来这次不想认怂,就用node v18,见招拆招,结果就报了下面那些glibc 、gcc版本过低的问题,然后搞了几个小时没搞好(我怕把环境搞坏了,用的本地虚拟机来编译glibc、gcc,结果gcc编了快2个小时了还没好,我也是服了,回头再战吧)

centos 7.9安装nodejs v18的一些问题

首先,node目前最新的长期支持版本是v18.18.2,但是,在centos7.9上,都是用不了的。可以看下面的具体报错,是node v18版本依赖了高版本的glic库,而这个库在centos 7.9上没有;同时,也需要安装高版本的gcc,才能运行不报错,而这个高版本的gcc在centos 7.9上也没有。

https://nodejs.org/en/download

代码语言:javascript
复制
tar -xJvf node-$VERSION-$DISTRO.tar.xz
cd node-v18.18.2-linux-x64

[root@node1 node-v18.18.2-linux-x64]# bin/npm

安装并配置

https://github.com/cctvckl/markdown-sample

可以参考这里

就是一堆目录和markdown

我这边上传到一个目录下:

代码语言:javascript
复制

[root@VM-0-6-centos temp-doc]# ll
total 20
drwxr-xr-x 2 root root 4096 Oct 21 16:39 archive
drwxr-xr-x 2 root root 4096 Oct 21 16:39 foundation
drwxr-xr-x 2 root root 4096 Oct 21 16:39 money

drwxr-xr-x 2 root root 4096 Oct 21 16:39 working-groups
[root@VM-0-6-centos temp-doc]# pwd
/root/doctest/temp-doc
[root@VM-0-6-centos temp-doc]#

然后安装官网:https://github.com/honkit/honkit

代码语言:javascript
复制
初始化:
[root@VM-0-6-centos temp-doc]# npm init --yes
Wrote to /root/doctest/temp-doc/package.json:

{
"name": "temp-doc",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo "Error: no test specified" && exit 1"
},
"keywords": [],
"author": "",
"license": "ISC"
}

安装依赖:

代码语言:javascript
复制
npm install honkit --save-dev

image-20231021164806790

代码语言:javascript
复制
[root@VM-0-6-centos temp-doc]#  npx honkit init
warn: no summary file in this book
info: create README.md
info: create SUMMARY.md
info: initialization is finished

然后,提示我们,没有summary文件(相当于目录),帮我们建了一个,但是建的这个基本没法用:

代码语言:javascript
复制
[root@VM-0-6-centos temp-doc]# ll

drwxr-xr-x 2 root root 4096 Oct 21 16:39 working-groups
[root@VM-0-6-centos temp-doc]# cat SUMMARY.md

Summary

这个文档,本来就是需要你自己手动建的,但这里可以先用我这边的,后边可以介绍,用插件根据文件夹那些来自动创建好SUMMARY文件

调试模式启动

代码语言:javascript
复制
[root@VM-0-6-centos temp-doc]# npx honkit serve
Live reload server started on port: 35729
Press CTRL+C to quit ...

info: >> Starting server ...
info: 6 plugins are installed
info: 6 explicitly listed
info: plugin "livereload" is loaded
info: plugin "highlight" is loaded
info: plugin "search" is loaded
info: plugin "lunr" is loaded
info: plugin "fontsettings" is loaded
info: plugin "theme-default" is loaded
info: found 1 pages
info: found 17 asset files
info: >> generation finished with success in 0.3s !
Serving book on http://localhost:4000

此时,通过访问ip:4000端口,就能看到效果,但我们实际部署,一般会编译成html,再通过nginx之类的,对外暴露成网站。

编译为html

其实在执行上面的npx honkit serve后,就生成了index.html和相关的资源文件,在当前目录的_book目录下:

image-20231021170724174

编译的命令:

代码语言:javascript
复制
[root@VM-0-6-centos temp-doc]# npx honkit build
info: 5 plugins are installed
info: 5 explicitly listed
info: plugin "highlight" is loaded
info: plugin "search" is loaded
info: plugin "lunr" is loaded
info: plugin "fontsettings" is loaded
info: plugin "theme-default" is loaded
info: found 1 pages
info: found 17 asset files
info: >> generation finished with success in 0.3s !

通过nginx发布为网站

关键配置如下:

代码语言:javascript
复制
 server {
listen 80;
server_name localhost;

    location /{
        root  /root/doctest/handbook-main/_book;
    }
}

效果

访问 http://ip

插件

自动生成SUMMARY.md

https://www.npmjs.com/package/gitbook-plugin-summary

Gitbook plugin to auto-generate SUMMARY.md

代码语言:javascript
复制
npm i gitbook-plugin-summary --save

新建一个book.json文件,写入如下内容:
{
"plugins": [
"summary"
]
}

[root@VM-0-6-centos temp-doc]# cat book.json
{
"plugins": [
"summary"
]
}

[root@VM-0-6-centos temp-doc]# npx honkit build
info: 6 plugins are installed
info: 6 explicitly listed
info: plugin "summary" is loaded
info: plugin "highlight" is loaded
info: plugin "search" is loaded
info: plugin "lunr" is loaded
info: plugin "fontsettings" is loaded
info: plugin "theme-default" is loaded
info: found 13 pages
info: found 6 asset files
gitbook-plugin-summary: SUMMARY.md generated successfully.
info: >> generation finished with success in 1.7s !

上面可以看到,加载了summary插件

底部左右导航按钮

https://www.npmjs.com/package/gitbook-plugin-bottom-navigation

image-20231021172259238

代码语言:javascript
复制
npm i gitbook-plugin-summary --save

[root@VM-0-6-centos temp-doc]# cat book.json
{
"plugins": [
"summary","bottom-navigation"
],
"pluginsConfig": {
"bottom-navigation": {
"iconColor": "#3884FE",
"titleColor": "#3884FE",
"borderColor": "#3884FE"
}
}
}

npx honkit build

image-20231021172739063

代码语言:javascript
复制
## 默认插件

在执行npx honkit build的输出中,可以看到,还有一些默认插件:

代码语言:javascript
复制
[root@VM-0-6-centos temp-doc]# npx honkit build
info: 7 plugins are installed
info: 7 explicitly listed
info: plugin "summary" is loaded
info: plugin "bottom-navigation" is loaded
info: plugin "highlight" is loaded
info: plugin "search" is loaded
info: plugin "lunr" is loaded
info: plugin "fontsettings" is loaded
info: plugin "theme-default" is loaded

默认插件也是可以去掉的,可以换成社区里更好的,语法大家网上找一下就有了。

book.json参考

我这边的一份简单的配置:

代码语言:javascript
复制
[root@VM-0-6-centos handbook-main]# cat book.json
{
"styles": {
"website": "styles/website.css"
},
"plugins": ["bottom-navigation",
"page-footer-ex", "collapsible-menu", "video", "page-treeview","page-toc-button" ],
"pluginsConfig": {
"page-treeview": {
"copyright": "",
"minHeaderCount": "2",
"minHeaderDeep": "2"
},
"styles": {
"website": "styles/website.css"
},
"page-toc-button": {
"maxTocDepth": 2,
"minTocSize": 2
},
"bottom-navigation": {
"iconColor": "#3884FE",
"titleColor": "#3884FE",
"borderColor": "#3884FE"
}
},
"variables": {
"org": "Enspiral",
"legalOrg": "Enspiral Foundation ltd"
}
}
