在一些没有互联网连接的网络场景中，如果我们需要安装一些必要的工具包，比如 iperf3，net-tools ，openss-server 等，可以提前先准备好离线安装包，拷贝到这些离线安装场景的设备上进行安装Step1. 查看软件依赖包列表 使用以下命令查看安装 openssh-server 所需的依赖包有哪些 sudo apt-cache depends iperf3 lijun@lijun-ubuntu:~/Downloads/iperf$ sudo apt-cache depends iperf3 iperf3 Depends: libc6 Depends: libiperf0Step2. 软件安装包下载使用以下命令可以仅下载软件安装包，下载结果为.deb 文件 sudo apt-get download lijun@lijun-ubuntu:~/Downloads/iperf$ sudo apt-get download iperf3 Get:1 http://cn.archive.ubuntu.com/ubuntu jammy/universe amd64 iperf3 amd64 3.9-1build1 [14.6 kB] Fetched 14.6 kB in 1s (16.8 kB/s) Step3. 软件依赖包递归下载以下命令将下载 iperf3 所有必需的依赖项，并将它们保存在当前工作目录中。此命令还将在errors.txt文件中记录下载过程中所出现的错误。 for i in $(apt-cache depends iperf3 | grep -E 'Depends|Recommends|Suggests' | cut -d ':' -f 2,3 | sed -e s/''/''/); do sudo apt-get download $i 2>>errors.txt; donelijun@lijun-ubuntu:~/Downloads/test$ for i in $(apt-cache depends iperf3 | grep -E 'Depends|Recommends|Suggests' | cut -d ':' -f 2,3 | sed -e s/''/''/); do sudo apt-get download $i 2>>errors.txt; done Get:1 http://cn.archive.ubuntu.com/ubuntu jammy-updates/main amd64 libc6 amd64 2.35-0ubuntu3.1 [3,235 kB] Fetched 3,235 kB in 3s (1,101 kB/s) Get:1 http://cn.archive.ubuntu.com/ubuntu jammy/universe amd64 libiperf0 amd64 3.9-1build1 [81.5 kB] Fetched 81.5 kB in 2s (50.9 kB/s) lijun@lijun-ubuntu:~/Downloads/test$ ls -lath total 3.2M -rw-rw-r-- 1 lijun lijun 386 6月 26 11:28 errors.txt drwxrwxr-x 2 lijun lijun 4.0K 6月 26 11:28 . drwxr-xr-x 8 lijun lijun 4.0K 6月 26 11:28 .. -rw-r--r-- 1 root root 3.1M 7月 12 2022 libc6_2.35-0ubuntu3.1_amd64.deb -rw-r--r-- 1 root root 80K 11月 23 2021 libiperf0_3.9-1build1_amd64.deb lijun@lijun-ubuntu:~/Downloads/test$ Step4. 软件包的打包压缩 和 解压缩 （tar.gz）打包压缩： tar -zcvf tar-name.tar.gz file-names : lijun@lijun-ubuntu:~/Downloads/test$ tar -zcvf iperf3.tar.gz *.deb iperf3_3.9-1build1_amd64.deb libc6_2.35-0ubuntu3.1_amd64.deb libiperf0_3.9-1build1_amd64.deb libsctp1_1.0.19+dfsg-1build1_amd64.deb lksctp-tools_1.0.19+dfsg-1build1_amd64.deb lijun@lijun-ubuntu:~/Downloads/test$ ls | grep *.tar.gz iperf3.tar.gz解压缩： tar -zxvf tar-name.tar.gz : lijun@lijun-ubuntu:~/Downloads/test$ tar -zxvf iperf3.tar.gz iperf3_3.9-1build1_amd64.deb libc6_2.35-0ubuntu3.1_amd64.deb libiperf0_3.9-1build1_amd64.deb libsctp1_1.0.19+dfsg-1build1_amd64.deb lksctp-tools_1.0.19+dfsg-1build1_amd64.deb lijun@lijun-ubuntu:~/Downloads/test$ Step5. 安装软件包使用以下命令来一次性安装所有的.deb安装包，如果软件的依赖包很多，一次性安装出错的话，这里可以考虑按照Step1 中的依赖包顺序来安装试下，同时需要按照报错信息尝试递归的安装依赖包本身所需的依赖包，比如 sudo dpkg -i *.deb lijun@lijun-ubuntu:~/Downloads/test$ sudo dpkg -i *.deb (Reading database ... 234250 files and directories currently installed.)
