https://www.tug.org/texlive/acquire-iso.html
该页面下有texlive最新版本ISO种子问题下载链接。
#2018https://www.tug.org/texlive/files/texlive2018-20180414.iso.torrent
TeXLive在国内下载源很多，现仅以清华大学和阿里云为例。
https://mirrors.tuna.tsinghua.edu.cn/##阿里云https://mirrors.aliyun.com/CTAN/systems/texlive/
找到常用发行版 iso 和应用工具安装包直接下载，点击应用软件，清华大学 TeXLive2018 下载链接如下
#2018年新版本https://mirrors.tuna.tsinghua.edu.cn/CTAN/systems/texlive/Images/texlive2018-20180414.iso
阿里云下载链接：
http://mirrors.aliyun.com/CTAN/systems/texlive/Images/
选择对应版本下载即可。
下载可以使用wget下载，也可以在Windows上面将ISO文件复制到系统目录。
下载完成就可以挂载ISO镜像。
CTAN官方网站ISO挂载教程如下。
mount -t iso9660 -o ro,loop,noauto /ISOFileDictory/texlive2018-20180414.iso /mnt
本机挂载记录如下：
dell@DELL-Server:~$ sudo mount -o loop texlive2018-20180414.iso /mnt/mount: /home/dell/texlive2016.iso is already mounteddell@DELL-Server:~$ ls /mnt/archive install-tl LICENSE.CTAN readme-html.dir release-texlive.txt tlpkgautorun.inf install-tl-advanced.bat LICENSE.TL readme-txt.dir source tl-tray-menu.exeindex.html install-tl-windows.bat README README.usergroups texlive-docdell@DELL-Server:~$
安装命令
dell@DELL-Server:~$ cd /mnt/dell@DELL-Server:/mnt$ sudo ./install-tl --gui
该命令可以在图形化界面下安装。
安装过程和完成截图如下。
安装界面有很多安装选项，无特殊要求直接点击安装texlive，等待安装过程完成。
完成安装后，卸载镜像。
sudo umount /mnt
也可以将ISO解压后复制到Linux系统。复制文件方法这里不再赘述。
增加环境变量。
# TeX Live 2016#命令可以直接复制运行，每次运行一条命令export TeXLiveMANPATH=/urs/local/texlive/2018/texmf-dist/doc/manexport TeXLiveINFOPATH=/usr/local/texlive/2018/texmf-dist/doc/info#64位系统export TeXLivePATH=/usr/local/texlive/2018/bin/x86_64-linux
具体安装路径请以安装时选择目录为准。
本机运行结果如下：
dell@DELL-Server:~$ export TeXLiveMANPATH=/urs/local/texlive/2018/texmf-dist/doc/mandell@DELL-Server:~$ export TeXLiveINFOPATH=/usr/local/texlive/2018/texmf-dist/doc/infodell@DELL-Server:~$ export TeXLivePATH=/usr/local/texlive/2018/bin/x86_64-linuxdell@DELL-Server:~$ echo $TeXLiveMANPATH/urs/local/texlive/2018/texmf-dist/doc/mandell@DELL-Server:~$ echo $TeXLiveINFOPATH/usr/local/texlive/2018/texmf-dist/doc/infodell@DELL-Server:~$ echo $TeXLivePATH/usr/local/texlive/2018/bin/x86_64-linuxdell@DELL-Server:~$
建议安装前将Windows字体复制到Linux，复制字体方法和复制ISO解压后文件方法一样，等待字体安装完成后再安装texlive。
在Linux系统字体目录下创建winfonts文件夹（可选项），前提是已复制字体到Linux主机。
#创建Windows字体文件目录，目录名称可自定义dell@DELL-Server:~$ sudo mkdir /usr/share/fonts/WindowsFonts#查看目录dell@DELL-Server:~$ ls /usr/share/fonts/cmap opentype truetype type1 WindowsFonts X11
复制字体到winfonts文件夹。
dell@DELL-Server:~$ sudo cp /home/dell/Fonts/* /usr/share/fonts/WindowsFonts/#查看字体复制情况dell@DELL-Server:~$ ls /usr/share/fonts/WindowsFonts/
安装字体命令。

Ubuntu网络安装TeXLive比较简单，只需要执行一条命令并等待安装完成。
首先要安装基础依赖软件。
sudo apt-get install libdigest-perl-md5-perl perl-tksudo apt install texlive-full
但该方法安装存在一个弊端，即不能更新宏包（包括所有Debian和Ubuntu发行版本）。
当我们执行命令
tlmgr update -all
我们可以使用
时会有报错。报错信息如下：
jiangjuan@OptiPlex-390:~$ tlmgr update --all(running on Debian, switching to user mode!)cannot setup TLPDB in /home/jiangjuan/texmf at /usr/bin/tlmgr line 5604.
其他tlmgr命令也无效。所以我们需要其他方法安装TeXLive。下文将加以介绍。
安装镜像中所有宏包均是打包时版本，部分软件包会在Ubuntu 安装源发布后更新，本方法可以解决安装源软件版本不能实时更新问题。部分Debian系发行版本执行tlmgr命令有问题，下文将给出一个解决方法。
首先，执行命令：
#一定要安装perl-tksudo apt install git perl-tk
安装git客户端,git客户端可以克隆github代码到本地。git完成后如下图。 
install-tl-ubuntuGitHub地址。
.
下面是重要环节，首先git 同步 install-tl-ubuntu代码到本机并安装。代码如下：
#克隆代码git clone https://github.com/scottkosty/install-tl-ubuntu.git#切换到安装目录cd cd install-tl-ubuntu#赋予安装文件可执行权限chmod +x ./install-tl-ubuntu#开始安装sudo ./install-tl-ubuntu#查看安装帮助文档，以下是部分帮助文档jiangjuan@jiangjuan-machine:~/install-tl-ubuntu$ ./install-tl-ubuntu --help | more USAGE sudo ./install-tl-ubuntu [OPTIONS] DESCRIPTION This script uses the TeX Live 2016 installer to install TeX Live so that LaTeX packages can be updated through CTAN with tlmgr. To do this, the official TeX Live 2016 installer is downloaded and used and apt is informed that TeX dependencies are satisfied. Thus, when you want to install a program with apt-get that depends on TeX Live, apt will not try to install the TeX Live packages from the Ubuntu repositories. If this script detects a previous TeX Live installation installed to the same place (/opt/texbin), the link will be updated to the new installation but the old installation (the place /opt/texbin points to) will not be removed and should be removed manually by the user if desired. This script must be run with sudo. Many recommend not installing TeX Live with sudo, in which case this script must be altered (please send a patch or post an enhancement request).--更多-
等待程序自动选择安装源并自完成安装，全程无需人工干预。
提示：需要注意该方法需要网络环境稳定，否则可能会出现反复重新安装情况。
程序安装完成后，开始菜单会增加一个选项--TeXLive Package Manager，通过该软件可以完成宏包更新和管理等操作。
提示：软件功能bug可能会随着作者更新软件而修复。
安装完成后，检查软件安装情况，可以执行命令。
xelatex -version
LaTeX示例代码如下，Windows将代码直接复制到文本编辑器（记事本，notepad++等）中，另存为英文名称.tex（Linux没有该限制），可在文本编辑器中再次打开，或者直接通过命令编译。
\documentclass{book}\usepackage{amsmath}\usepackage{ctex}%\usepackage{ctex}%(PDF)LaTeX编译方式请选择此行，注释上一行代码\begin{document}你好，中国。勾股定律$$a^2+b^2=c^2$$Happy TeXing.\end{document} Linux系统可以将代码保存至/home/dell/文档/tex/Hello目录下，该目录是笔者电脑目录，可根据实际情况选择保存目录，或者放置到其他任意目录。
/home/dell/文档/tex/Hello/hello.tex
Linux编译文件操作步骤如下：
#切换到tex源文件目录cd /home/dell/文档/Hello/#xelatex命令编译文件，可选其他选项xelatex hello.tex
等待编译过程完成即可。
下面贴出一个编译过程。
