docker的pdflatex环境配置的方法步骤

技术背景

Latex在文档撰写方面是不可或缺的工具，尤其是在写文章方面，是必须要用到的文字排版工具。但是latex的环境部署并不是一个特别人性化的操作，尤其是在各种不同的平台上操作是完全不一样的，还经常容易报错。我们可以一个一个的去解决报错问题，但是这需要耗费极大的精力和时间，所以很多人选择了直接在overleaf进行latex的创作。但其实overleaf也有它的缺点，比如免费版本的带宽和速度都比较受限，尤其是在国内的网络，访问速度可谓是”一绝“。因此这里我们介绍一个更加人性化的方案，而且对各大平台的兼容性非常都非常好：使用docker来部署latex环境。

Docker的基本操作

在各大平台的官方源里面应该都会有提供docker容器，因此这里我们也不过多的赘述。作者过去写过一篇关于使用docker来部署MindSpore开发环境的博客，感兴趣的读者可以当作是拓展文章来阅读一下。

首先我们在Manjaro Linux平台上启动docker（在其他平台上的操作可能有区别，比如service start docker等）：

[dechin-root tex]# systemctl start docker

注意上述指令要在root帐号下才能够启动，如果要选择在非root帐号下操作，docker容器是不支持的，但是我们可以选择singularity这一类似的容器解决方案，相关内容可以参考这篇博客。启动服务之后，正常状态下我们可以看到docker的status是处于active或者running的状态：

[dechin-root tex]# systemctl status docker ● docker.service – Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disab> Active: active (running) since Sun 2021-03-28 18:50:47 CST; 7s ago TriggeredBy: ● docker.socket Docs: https://docs.docker.com Main PID: 25366 (dockerd) Tasks: 123 (limit: 47875) Memory: 219.1M CGroup: /system.slice/docker.service ├─25366 /usr/bin/dockerd -H fd:// └─25378 containerd –config /var/run/docker/containerd/containerd.toml –log-l>

拉取容器镜像

首先我们可以访问dockerhub官网

搜索一下是否存在我们所需要的容器镜像，比如我们的搜索结果如下：

可以看到这里有很多的选项，一般我们可以直接选择星星最高的容器镜像进行下载使用：

[dechin-root tex]# docker pull fbenz/pdflatex Using default tag: latest latest: Pulling from fbenz/pdflatex f22ccc0b8772: Already exists 3cf8fb62ba5f: Already exists e80c964ece6a: Already exists 9aa2583757a3: Pull complete 2c3d7890d583: Pull complete Digest: sha256:6ecca11b1a203faed5c0a2ace2a13aac100dd19d7a4e0db0474283bcded3c041 Status: Downloaded newer image for fbenz/pdflatex:latest docker.io/fbenz/pdflatex:latest

下载需要一段的时间。下载完成后，可以在本地镜像仓库中找到刚才下载的这个镜像文件：

[dechin-root tex]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE fbenz/pdflatex latest 8e7742722956 3 months ago 24GB

我们可以测试一下这个容器镜像中的pdflatex功能是否正常：

[dechin-root tex]# docker run -it fbenz/pdflatex pdflatex –help Usage: pdftex [OPTION]… [TEXNAME[.tex]] [COMMANDS] or: pdftex [OPTION]… FIRST-LINE or: pdftex [OPTION]… &FMT ARGS Run pdfTeX on TEXNAME, usually creating TEXNAME.pdf. Any remaining COMMANDS are processed as pdfTeX input, after TEXNAME is read. If the first line of TEXNAME is %&FMT, and FMT is an existing .fmt file, use it. Else use `NAME.fmt, where NAME is the program invocation name, most commonly `pdftex. Alternatively, if the first non-option argument begins with a backslash, interpret all non-option arguments as a line of pdfTeX input. Alternatively, if the first non-option argument begins with a &, the next word is taken as the FMT to read, overriding all else. Any remaining arguments are processed as above. If no arguments or options are specified, prompt for input. -draftmode switch on draft mode (generates no output PDF) -enc enable encTeX extensions such as mubyte -etex enable e-TeX extensions [-no]-file-line-error disable/enable file:line:error style messages -fmt=FMTNAME use FMTNAME instead of program name or a %& line -halt-on-error stop processing at the first error -ini be pdfinitex, for dumping formats; this is implicitly true if the program name is `pdfinitex -interaction=STRING set interaction mode (STRING=batchmode/nonstopmode/ scrollmode/errorstopmode) -ipc send DVI output to a socket as well as the usual output file -ipc-start as -ipc, and also start the server at the other end -jobname=STRING set the job name to STRING -kpathsea-debug=NUMBER set path searching debugging flags according to the bits of NUMBER [-no]-mktex=FMT disable/enable mktexFMT generation (FMT=tex/tfm/pk) -mltex enable MLTeX extensions such as charsubdef -output-comment=STRING use STRING for DVI file comment instead of date (no effect for PDF) -output-directory=DIR use existing DIR as the directory to write files in -output-format=FORMAT use FORMAT for job output; FORMAT is `dvi or `pdf [-no]-parse-first-line disable/enable parsing of first line of input file -progname=STRING set program (and fmt) name to STRING -recorder enable filename recorder [-no]-shell-escape disable/enable write18{SHELL COMMAND} -shell-restricted enable restricted write18 -src-specials insert source specials into the DVI file -src-specials=WHERE insert source specials in certain places of the DVI file. WHERE is a comma-separated value list: cr display hbox math par parend vbox -synctex=NUMBER generate SyncTeX data for previewers according to bits of NUMBER (`man synctex for details) -translate-file=TCXNAME use the TCX file TCXNAME -8bit make all characters printable by default -help display this help and exit -version output version information and exit pdfTeX home page: <http://pdftex.org> Email bug reports to pdftex@tug.org.

当我们看到help指令运行成功时，就表明容器镜像可以正常使用。使用容器还有一点需要注意的是，如果我们直接用docker run -it fbenz/pdflatex的话，没有绑定本地的目录，这样是无法看到本地所撰写的tex文件的。因此我们一般需要在运行的时候加上-v的选项来绑定本地的目录，基本使用方法是：-v 本地目录:容器目录，注意需要使用绝对路径，不能使用相对路径。

编译Tex文件

在上述章节中完成基于docker的pdflatex环境部署之后，我们可以开始撰写一些简单的tex文件用来测试一下环境。

Hello World

首先最简单的我们测试一个hello world的案例，仅在pdf文档中输出一个Hello World!的字样，具体tex代码如下：

[dechin@dechin-manjaro tex]$ cat hello_world.tex documentclass{article} begin{document} Hello world! end{document}

使用方法也不难，首先我们运行docker容器，注意需要绑定一个本地路径，然后进入到容器内对应的目录下：

[dechin-root tex]# docker run -it -v /home/dechin/projects/2021-python/tex/:/home/ fbenz/pdflatex root@d7ed2229a244:/# ll total 72 drwxr-xr-x 1 root root 4096 Mar 28 11:07 ./ drwxr-xr-x 1 root root 4096 Mar 28 11:07 ../ -rwxr-xr-x 1 root root 0 Mar 28 11:07 .dockerenv* drwxr-xr-x 2 root root 4096 Nov 19 13:09 bin/ drwxr-xr-x 2 root root 4096 Apr 24 2018 boot/ drwxr-xr-x 5 root root 360 Mar 28 11:07 dev/ drwxr-xr-x 1 root root 4096 Mar 28 11:07 etc/ drwxr-xr-x 2 1000 1000 4096 Mar 28 04:43 home/ drwxr-xr-x 1 root root 4096 May 23 2017 lib/ drwxr-xr-x 2 root root 4096 Nov 19 13:09 lib64/ drwxr-xr-x 2 root root 4096 Nov 19 13:07 media/ drwxr-xr-x 2 root root 4096 Nov 19 13:07 mnt/ drwxr-xr-x 2 root root 4096 Nov 19 13:07 opt/ dr-xr-xr-x 323 root root 0 Mar 28 11:07 proc/ drwx—— 2 root root 4096 Nov 19 13:09 root/ drwxr-xr-x 1 root root 4096 Nov 25 22:25 run/ drwxr-xr-x 1 root root 4096 Nov 25 22:25 sbin/ drwxr-xr-x 2 root root 4096 Nov 19 13:07 srv/ dr-xr-xr-x 13 root root 0 Mar 28 11:07 sys/ drwxrwxrwt 1 root root 4096 Nov 28 18:34 tmp/ drwxr-xr-x 1 root root 4096 Nov 19 13:07 usr/ drwxr-xr-x 1 root root 4096 Nov 19 13:09 var/ root@d7ed2229a244:/# cd home/ root@d7ed2229a244:/home# ll total 12 drwxr-xr-x 2 1000 1000 4096 Mar 28 04:43 ./ drwxr-xr-x 1 root root 4096 Mar 28 11:07 ../ -rw-r–r– 1 1000 1000 69 Mar 28 04:43 hello_world.tex

我们看到在容器内的目录下也能够看到这个tex文件，说明路径的绑定成功的执行了。运行指令很简单，直接在docker容器内运行pdflatex your_file.tex即可：

root@d7ed2229a244:/home# pdflatex hello_world.tex This is pdfTeX, Version 3.14159265-2.6-1.40.18 (TeX Live 2017/Debian) (preloaded format=pdflatex) restricted write18 enabled. entering extended mode (./hello_world.tex LaTeX2e <2017-04-15> Babel <3.18> and hyphenation patterns for 84 language(s) loaded.

运行完成后我们在目录中看到了几个新生成的文件，如果用root改成777的权限，那么在本地的非root帐号就可以对其进行编辑，否则就只能查看。我们可以在本地打开这个pdf文件看看：

可以看到这个pdf文件生成成功。

测试公式

上面hello world的案例比较简单，让我们来测试一下最常用的数学公式是否有问题：

[dechin@dechin-manjaro tex]$ cat equation_test.tex documentclass{article} begin{document} Hello world! begin{equation} e^{iHt}left|psiright> end{equation} end{document}

类似于上一章节的，我们也需要进入到容器的内部执行相关的指令，最后获得如下所示的一个pdf文件：

我们可以看到公式显示也是正常的。

量子线路图

最后我们测试一个比较难的，在前面写过一篇关于用ProjectQ生成Latex格式的量子线路图的博客，其中生成了如下所示的一个tex文件：

[dechin@dechin-manjaro quantum-circuit]$ cat circuit.tex documentclass{standalone} usepackage[margin=1in]{geometry} usepackage[hang,small,bf]{caption} usepackage{tikz} usepackage{braket} usetikzlibrary{backgrounds,shadows.blur,fit,decorations.pathreplacing,shapes} begin{document} begin{tikzpicture}[scale=0.8, transform shape] tikzstyle{basicshadow}=[blur shadow={shadow blur steps=8, shadow xshift=0.7pt, shadow yshift=-0.7pt, shadow scale=1.02}]tikzstyle{basic}=[draw,fill=white,basicshadow] tikzstyle{operator}=[basic,minimum size=1.5em] tikzstyle{phase}=[fill=black,shape=circle,minimum size=0.1cm,inner sep=0pt,outer sep=0pt,draw=black] tikzstyle{none}=[inner sep=0pt,outer sep=-.5pt,minimum height=0.5cm+1pt] tikzstyle{measure}=[operator,inner sep=0pt,minimum height=0.5cm, minimum width=0.75cm] tikzstyle{xstyle}=[circle,basic,minimum height=0.35cm,minimum width=0.35cm,inner sep=-1pt,very thin] tikzset{ shadowed/.style={preaction={transform canvas={shift={(0.5pt,-0.5pt)}}, draw=gray, opacity=0.4}}, } tikzstyle{swapstyle}=[inner sep=-1pt, outer sep=-1pt, minimum width=0pt] tikzstyle{edgestyle}=[very thin] node[none] (line0_gate0) at (0.1,-0) {$Ket{0}$}; node[none] (line0_gate1) at (0.5,-0) {}; node[none,minimum height=0.5cm,outer sep=0] (line0_gate2) at (0.75,-0) {}; node[none] (line0_gate3) at (1.0,-0) {}; draw[operator,edgestyle,outer sep=0.5cm] ([yshift=0.25cm]line0_gate1) rectangle ([yshift=-0.25cm]line0_gate3) node[pos=.5] {H}; draw (line0_gate0) edge[edgestyle] (line0_gate1); node[none] (line1_gate0) at (0.1,-1) {$Ket{0}$}; node[none] (line1_gate1) at (0.5,-1) {}; node[none,minimum height=0.5cm,outer sep=0] (line1_gate2) at (0.75,-1) {}; node[none] (line1_gate3) at (1.0,-1) {}; draw[operator,edgestyle,outer sep=0.5cm] ([yshift=0.25cm]line1_gate1) rectangle ([yshift=-0.25cm]line1_gate3) node[pos=.5] {H}; draw (line1_gate0) edge[edgestyle] (line1_gate1); node[none] (line2_gate0) at (0.1,-2) {$Ket{0}$}; node[none] (line2_gate1) at (0.5,-2) {}; node[none,minimum height=0.5cm,outer sep=0] (line2_gate2) at (0.75,-2) {}; node[none] (line2_gate3) at (1.0,-2) {}; draw[operator,edgestyle,outer sep=0.5cm] ([yshift=0.25cm]line2_gate1) rectangle ([yshift=-0.25cm]line2_gate3) node[pos=.5] {H}; draw (line2_gate0) edge[edgestyle] (line2_gate1); node[xstyle] (line1_gate4) at (1.4000000000000001,-1) {}; draw[edgestyle] (line1_gate4.north)–(line1_gate4.south); draw[edgestyle] (line1_gate4.west)–(line1_gate4.east); node[phase] (line2_gate4) at (1.4000000000000001,-2) {}; draw (line2_gate4) edge[edgestyle] (line1_gate4); draw (line1_gate3) edge[edgestyle] (line1_gate4); draw (line2_gate3) edge[edgestyle] (line2_gate4); node[xstyle] (line0_gate4) at (1.9500000000000002,-0) {}; draw[edgestyle] (line0_gate4.north)–(line0_gate4.south); draw[edgestyle] (line0_gate4.west)–(line0_gate4.east); node[phase] (line1_gate5) at (1.9500000000000002,-1) {}; draw (line1_gate5) edge[edgestyle] (line0_gate4); draw (line0_gate3) edge[edgestyle] (line0_gate4); draw (line1_gate4) edge[edgestyle] (line1_gate5); node[measure,edgestyle] (line0_gate5) at (2.6000000000000005,-0) {}; draw[edgestyle] ([yshift=-0.18cm,xshift=0.07500000000000001cm]line0_gate5.west) to [out=60,in=180] ([yshift=0.035cm]line0_gate5.center) to [out=0, in=120] ([yshift=-0.18cm,xshift=-0.07500000000000001cm]line0_gate5.east); draw[edgestyle] ([yshift=-0.18cm]line0_gate5.center) to ([yshift=-0.07500000000000001cm,xshift=-0.18cm]line0_gate5.north east); draw (line0_gate4) edge[edgestyle] (line0_gate5); node[measure,edgestyle] (line1_gate6) at (2.6000000000000005,-1) {}; draw[edgestyle] ([yshift=-0.18cm,xshift=0.07500000000000001cm]line1_gate6.west) to [out=60,in=180] ([yshift=0.035cm]line1_gate6.center) to [out=0, in=120] ([yshift=-0.18cm,xshift=-0.07500000000000001cm]line1_gate6.east); draw[edgestyle] ([yshift=-0.18cm]line1_gate6.center) to ([yshift=-0.07500000000000001cm,xshift=-0.18cm]line1_gate6.north east); draw (line1_gate5) edge[edgestyle] (line1_gate6); node[measure,edgestyle] (line2_gate5) at (2.0500000000000003,-2) {}; draw[edgestyle] ([yshift=-0.18cm,xshift=0.07500000000000001cm]line2_gate5.west) to [out=60,in=180] ([yshift=0.035cm]line2_gate5.center) to [out=0, in=120] ([yshift=-0.18cm,xshift=-0.07500000000000001cm]line2_gate5.east); draw[edgestyle] ([yshift=-0.18cm]line2_gate5.center) to ([yshift=-0.07500000000000001cm,xshift=-0.18cm]line2_gate5.north east); draw (line2_gate4) edge[edgestyle] (line2_gate5); end{tikzpicture} end{document}

这个文件不仅结构复杂，对周边所依赖的tex文件其实也不少，此前在其他平台（Win10）测试这个tex文件的编译的时候，都需要手动的去下载很多的依赖文件，然后放到同一个文件夹下才能正常运行和使用。这里我们直接运行，发现也可以生成这个pdf文件：

说明环境里面确实已经包含了很多必备的工具，跟overleaf的环境应该是比较类似的，使得我们可以在本地非常人性化的、轻便的可以编译tex文件。

总结概要

为了在本地构建一个可用性强、易于部署的环境，我们选择了放弃直接安装pdflatex的方案，以及线上的overleaf的方案。这些方案各有利弊，但是综合起来看，对于个人使用的环境而言，还是在本地使用docker镜像直接部署一个tex编译环境是最方便、最人性化的。
