在 Ubuntu 20.04 上静默安装matlab 实践-Toy模板网

这篇具有很好参考价值的文章主要介绍了在 Ubuntu 20.04 上静默安装matlab 实践。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

需求：

某服务端业务需要调用 matlab
为方便迭代发布，需要支持基于 docker 的自动化部署（CD）

方案对比

使用 Matlab 官方 docker 镜像

一键安装，使用方便
官方镜像仅支持网络验证
官方镜像仅支持基础功能版、深度学习版两个版本，功能不全

使用 matlab runtime

需要将编写好的 matlab 程序打包成对应框架（如：python、c++ 等）SDK。存在兼容性问题，同时操作较为复杂

使用 matlab server

没有用过
看文档，貌似用起来成本较大

定制 docker 镜像

使用 ubuntu：20.04 作为基础镜像，在容器中安装 matlab

操作简单。需求方仅需要把 matlab 代码交付给开发人员，就可以使用
灵活性强。可以根据具体业务安装对应模块
兼容性好。理论上，服务端的执行效果和开发时的运行效果一致

使用规范

matlab 代码使用 pcode 工具混淆后部署到服务端

构建镜像

基础镜像

目的：加快实验速度，同时作为后续部署的基础镜像

FROM ubuntu:20.04
COPY . /root
RUN rm -f /etc/apt/sources.list && cp /root/sources.list /etc/apt/sources.list && rm -rf /var/lib/apt/lists/* && apt update && \
apt-get install -y python3 && apt-get install -y python3-pip && \
pip config --global set global.index-url http://mirrors.piprepohost.com/repository/pypi/simple/ && pip config --global set install.trusted-host mirrors.piprepohost.com && \
apt-get install -y libx11-6 && apt-get install -y libxt6 && apt-get install -y libglib2.0-0 && \
apt-get clean && apt-get -y autoremove && rm -rf /var/lib/apt/lists/*

Install

方法一：把容器保存成镜像

这里是把 matlab ISO 安装包映射到 docker 容器中。然后把容器打包成镜像。

// install
// txt 内容详见文章末尾
./install -inputFile inputFile.txt

// run
// 如果没有安装 jre 或其他 java 开发环境，需要携带 -nojvm 参数
/matlabroot/bin/matlab -nodisplay -nojvm

// install python engine allowing call matlab from python
cd /matlabroot/bin/extern//engines/python
python3 setup.py install

# 把容器保存为镜像
docker commit <containerid> <tag>

# 接下来可以通过以下两种方式分发镜像

# 上传到 harbor
docker push <tag>

# 保存成文件
docker save -o <filename>.tar <src-image-tag>
# 通过下面的命令导入镜像
# 导入后，新导入的镜像是没有 tag 的，记得打上 tag
docker load --input <filename>.tar

方法二：通过 Dockerfile 构建镜像

使用这种方法时，不能把 matlab 安装包放到 context 中，因为安装文件太大，会导致发送给 daemon 的时候崩溃或者卡死。

建议使用多阶段构建，在第一个阶段完成安装，第二个阶段保留安装完的数据。

构建时推荐使用 ADD 指令，从远端下载安装文件，然后执行安装 matlab 相关命令。

问题集合

no more space

matlab.internal.engine.input
outputFile
no more space

// 查看磁盘占用情况，大概率是 docker 使用的磁盘空间满了
du -h
df -h

// 可以在 /etc/docker/daemon.json 中添加/修改 data-root 字段，选择空间最大的磁盘
// 改完后注意同步数据（把之前磁盘空间的内容拷贝到新磁盘空间，否则之前所有的 docker 内容都看不到）
"data-root"

// 重启 docker
systemctl daemonreload
systemctl restart docker

not found

matlab 编码问题
加密系统自动加密问题
pcode 混淆

在 dockerfile 使用 apt

当在 dockerfile 使用 apt 的时候，如果出问题，可以考虑设置如下环境变量。该环境变量有很多值，请自行 baidu

DEBIAN_FRONTEND=noninteractive

图形化安装

如果要图形化安装（使用 matlab 的安装 GUI 引导）。最好是注销当前账户，然后使用 root 登录系统。

如果是使用如下方式安装，会出现 GUI 看不到的情况

sudo su
./install

怀疑是此时的 X11 转发不能和当前账户共用导致。

installer_input.txt

这是 demo 样例，大家注意根据自己情况修改文件中的参数。文章来源地址https://www.toymoban.com/news/detail-531047.html
