TeX live是可以作为Tex文件生成的软件系统，提供了在Unix（包括LInux）环境下的完整Tex 系统。
由于前期我们提到了用Texshade 进行序列的可视化，但是最近感觉那文章中仅仅介绍Texshade的使用，但没有对TeXlive作为环境的介绍，因此今天就讲讲在Ubuntu下安装TeXlive的方法并结合前面的Texshade对多重序列比对进行可视化进行进一步完善。
首先是安装软件
参考网站指导中的描述：
http://tug.org/texlive/acquire-mirror.html
选择清华镜像进行安装：
访问镜像列表网站
选择清华镜像
找到后查看路径：
https://mirrors.tuna.tsinghua.edu.cn/CTAN/systems/texlive/Images/
对应路径中的文件
然后进行下载

TeX Live ISO Images
-------------------
This directory contains the ISO image for the official TeX Live
release; md5 and sha512 checksums are provided, and the sha checksum is
GPG-signed. The generic names (texliveYYYY.iso and texlive.iso) are
symlinks to the dated release .iso.
The TeX Live web pages <https://tug.org/texlive/> have information on:
- other ways to acquire the distribution <https://tug.org/texlive/acquire.html>,
- quick installation <https://tug.org/texlive/quickinstall.html>,
- documentation <https://tug.org/texlive/doc.html>,
- reporting bugs and known issues <https://tug.org/texlive/bugs.html>,
and more.
Instead of dealing with this giant image, for typical use we recommend
the small installer package(s)
<https://tug.org/texlive/acquire-netinstall.html> available from
CTAN <https://ctan.org/>).
If you have problems with installation or running TeX after
installation, please check your environment variables: settings,
including your PATH, that end up referencing previously-installed TeX
systems (TeX Live or otherwise), can cause trouble, especially on Windows.

下载后的结果，经过md5sum进行计算后校验完整性。
接下来进行安装
yeyuntian@yeyuntian-RESCUER-R720-15IKBN:~/Software/texlive$ sudo mount texlive2018-20180414.iso /mnt/
yeyuntian@yeyuntian-RESCUER-R720-15IKBN:~/Software/texlive$ sudo perl /mnt/install-tl
#然后 进入一个界面后 输入 I 后回车
最后安装完成后进行路径配置
yeyuntian@yeyuntian-RESCUER-R720-15IKBN:~$ echo 'export PATH=/usr/local/texlive/2018/bin/x86_64-linux:$PATH' >> ~/.bashrc
yeyuntian@yeyuntian-RESCUER-R720-15IKBN:~$ echo 'export MANPATH=/usr/local/texlive/2018/texmf-dist/doc/man:$MANPATH' >> ~/.bashrc
yeyuntian@yeyuntian-RESCUER-R720-15IKBN:~$ echo 'export INFOPATH=/usr/local/texlive/2018/texmf-dist/doc/info:$INFOPATH' >> ~/.bashrc
yeyuntian@yeyuntian-RESCUER-R720-15IKBN:~$ tail ~/.bashrc

yeyuntian@yeyuntian-RESCUER-R720-15IKBN:~$ source ~/.bashrc
yeyuntian@yeyuntian-RESCUER-R720-15IKBN:~$ which pdftex
/usr/local/texlive/2018/bin/x86_64-linux/pdftex
至此，Texlive就已经安装完毕了。
配置完成后的验证
由于使用Texlive主要是用于构建多重序列比对，我们就再次进行一次尝试看能不能完成以前的工作。

最后我们需要补充一些关于 TeXlive 在VScode中搭建编写环境
参考：
Visual Studio Code 搭建 LaTeX 编写环境
如何在 VS Code 上编写 LaTeX（附入门指南）
前面已经介绍了如何安装VScode以及TeXlive，所以在此就继续先讲如何将两者结合起来
