篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了[wiki--gitit]在Linux系统搭建gitit wiki相关的知识,希望对你有一定的参考价值。
简述
对于喜欢用markdown写博客或做一些笔记,或者做学习知识库整理……等等之类的,gitit wiki是不错的wiki系统选择。因为一般的markdown语法是很简单的,以至于太简单而许多需要使用稍微复杂些的图表之类的,就不能太好的支持,因此是比较影响书写的。因此对于markdown就出现了许多的Extended的版本,这其中有个Pandoc的,使用支持pandoc扩展语法的markdown写wiki,那么wiki原始.md文件,可以通过强大的Pandoc工具,可以在书籍格式、PDF格式、word格式、epub格式、html格式……等等之间进行自动的生成,甚至可以生成PPT slide。
而gitit wiki系统,就可以显示这些支持pandoc extension的markdown语法的.md文件进行显示,有各种链接、图表展示等功能,很适合打造自己的私人wiki系统。
接下来介绍如何在Linux系统(可以是自己的Linux Server)上部署gitit wiki,之后自己可以使用自己的PC电脑进行登陆和wiki的维护与更新,只要联网,随时随地访问和更新。
Haskell开发工具安装
Why Haskell? 因为gitit是使用Haskell开发的,gitit的源码在github,因此Linux的方式是,将source code clone过来,然后安装Haskell开发工具,然后对gitit的源码进行编译和安装,这样就达到了安装gitit的目的。
stack(首选,最可靠)
stack就是Haskell的开发工具,“Stack is a cross-platform program for developing Haskell projects.”跨平台。关于stack的说明以及安装,可参考The Haskell Tool Stack
我在自己的64 bit的Debian系统,使用如下命令安装stack:
curl -sSL https://get.haskellstack.org/ | sh
# 或如下命令(Debian使用curl可以成功,Ubuntu下使用wget才成功,所以这两个可以根据情况试一试)
wget -qO- https://get.haskellstack.org/ | sh
不过一开始并不能成功安装,shell给出了如下的log:
Detected Linux distribution: debian
Installing dependencies...
sudo: unable to resolve host my_host_name
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libffi-dev
E: Unable to locate package libgmp-dev
E: Unable to locate package zlib1g-dev
Installing apt packages failed. Please run 'apt-get update' and try again.
于是按照提示输入:
apt-get update
果然更新了不少东西,然后再次输入上面的“curl -sSL https://get.haskellstack.org/ | sh”,此时就能安装成功了:
root@my_host_name:~# curl -sSL https://get.haskellstack.org/ | sh
Detected Linux distribution: debian

Installing Stack to: /usr/local/bin/stack...
-------------------------------------------------------------------------------
Stack has been installed to: /usr/local/bin/stack
WARNING: '/root/.local/bin' is not on your PATH.
For best results, please add it to the beginning of PATH in your profile.
这里看到了上面的WARNING提示,于是使用下面的命令将’/root/.local/bin’加入到环境变量PATH中:
PATH=$PATH:/root/.local/bin
#通过“echo $PATH”可以查看是否已经加入PATH中
在上面步骤完成后,最好还使用下面的命令更新下stack,以便避免系统更新带来的问题:
stack upgrade
Haskell Platform(仅作备选介绍,Debian下实测未成功)
如果不想使用stack,Debian中可以安装Haskell Platform,不过试了下,后续安装等待了很久都没有动静:
sudo apt-get install haskell-platform
gitit编译与安装
如果使用stack工具
首先安装git工具–“apt-get install git”,然后运行如下命令,分别是clone gitit源代码,在stack中编译与安装gitit:
git clone https://github.com/jgm/gitit
cd gitit
stack install
不过在Debian上使用stack install时,从log看貌似有些东西要从亚马孙awx镜像中去下载,好几次出现了connection timeout,不过尝试了多次,并中途用了stack setup后,stack install终于可以开始运作了,不过整个编译过程相对是比较缓慢的。
在该过程结束后,貌似gitit没有成功安装,因为gitit命令提示找不到……
没办法,后面换用Ubuntu系统再尝试,在使用stack install命令后,等了一个下午,之后发现仍然卡在:
Updating package index Hackage (mirrored at https://s3.amazonaws.com/hackage.fpcomplete.com/) ...
这里没动,没办法,停止后再次使用stack install尝试,然后终于开始看到mirror连接到了,开始Progress中了。
如果使用Haskell Platform(备用,Debian下用了下未能成功)
使用如下的命令:
cabal update
cabal install gitit
使用cabal update命令后,会看到先找/root/.cabal/config,没有找到就会创建默认的,然后再去hackage.haskell.org下载最新的package。
不过使用haskell platform, 使用cabal install安装clone下来的本地的gitit时一直出现问题:
Resolving dependencies...
cabal: Could not resolve dependencies:
trying: gitit-0.12.2.1 (user goal)
next goal: base (dependency of gitit-0.12.2.1)

3.0.3.2, 3.0.3.1 (global constraint requires installed instance)
Dependency tree exhaustively searched.
而使用“cabal install gitit”安装时,也是类似的提示base不符合。
这里不清楚什么原因,可能是gitit版本更新到了0.12.2造成了系统中dependencies的兼容问题了。
