一、依赖包安装
1.1 离线安装
在无网环境部署服务器时，需要离线安装很多软件，如gcc, cmake,tmux等，这时就要提前在有网环境下下载离线安装包。
有的软件只需要一个单独的deb包安装即可，如net-tools，而有的软件有很多的依赖包，如gcc，这时就需要一个简单的方法来批量下载所有依赖deb包。
这里以在ubuntu系统安装cmake为例，介绍如何安装cmake，首先检查包是否已经安装。
以下两条命令均可以检查包是否已经安装：
root@rk3399:/opt# dpkg -l | grep cmake
root@rk3399:/opt# apt list --installed | grep cmake1.1.1 查看依赖
这里以cmake为例：
root@rk3399:/opt# apt-cache depends cmake
cmake
Depends: libarchive13
Depends: libc6
Depends: libcurl4
Depends: libexpat1
Depends: libgcc-s1
Depends: libjsoncpp25
Depends: librhash0
Depends: libstdc++6
Depends: libuv1
Depends: zlib1g
Depends: cmake-data
Depends: procps
Recommends: gcc
Recommends: make
make-guile

Suggests: ninja-build

下载deb有两种方式，第一种方式是在服务器通过命令在线下载；
root@rk3399:/opt# mkdir cmake
root@rk3399:/opt# cd cmake
root@rk3399:/opt/cmake# apt-get download $(apt-cache depends --recurse --no-recommends --no-suggests --no-conflicts --no-breaks --no-replaces --no-enhances --no-pre-depends cmake | grep "^\w")xxxxxxxxxx root@rk3399:/opt# mkdir cmakeroot@rk3399:/opt# cd cmakeroot@rk3399:/opt/cmake# apt-get download $(apt-cache depends --recurse --no-recommends --no-suggests --no-conflicts --no-breaks --no-replaces --no-enhances --no-pre-depends cmake | grep "^\w")apt-get download $(apt-cache depends --recurse --no-recommends --no-suggests --no-conflicts --no-breaks --no-replaces --no-enhances --no-pre-depends cmake | grep "^\w")

Description: cross-platform, open-source make system
CMake is used to control the software compilation process using
simple platform and compiler independent configuration files. CMake
generates native makefiles and workspaces that can be used in the
compiler environment of your choice. CMake is quite sophisticated: it
is possible to support complex environments requiring system
configuration, pre-processor generation, code generation, and template
instantiation.
.
CMake was developed by Kitware as part of the NLM Insight
Segmentation and Registration Toolkit project. The ASCI VIEWS project
also provided support in the context of their parallel computation
environment. Other sponsors include the Insight, VTK, and VXL open
source software communities.
N: There is 1 additional record. Please use the '-a' switch to see it 接着运行安装命令开始安装：
# Update the package index
root@rk3399:/opt# sudo apt-get update
# Install cmake deb package
root@rk3399:/opt#sudo apt-get install cmake1.2.2 安装指定版本
比如我们想在ubuntu 22.04版本下安装其它版本，可以到《https://ubuntu.pkgs.org/》查找是否存在其他版本的deb，如果有的话，可以点击相应链接跳转到包信息页面，在Install Howto中获取安装命令：
# Update the package index:
root@rk3399:/opt#sudo apt-get update
# Install cmake-qt-gui deb package:
root@rk3399:/opt# sudo apt-get install cmake-qt-gui当然如果安装的版本的deb包在ubuntu镜像源中无法找到，那么可以考虑源码编译安装。
