ubuntu uses apt get to make offline package (take mysql as an example)
Recently, I am studying the deployment of engineering software. Although this is the work of operation and maintenance, it is quite interesting.
Question: what factors need to be considered in software environment configuration
- There are two ways to install the software
- make installation, you need to solve the dependency problem by yourself
- Apt get installation, stable, automatic configuration service
- How to install the software without a network:
- Download files by yourself
- Using apt get offline package.
The text adopts the installation method of apt get offline package.
Install ubuntu, using apt get package manager. Some operations of apt get are not described here.
User is used to configure the installation package path as / home / user / corsface? Install/
Self made offline package take mysql as an example
Download a software
apt-cache search mysql # Download mysql contains related dependencies but does not install sudo apt-get install -d mysql-server-5.6
Make offline package
A shell script
# Navigate to your own installation package folder cd /home/user/CorsFace_install # Create installation package mkdir OfflinePackage # The software downloaded by apt get package manager is placed in / var/cache/apt/archives folder, and the software is stored in its own offline package. cp -r /var/cache/apt/archives /home/user/CorsFace_install/OfflinePackage # Authority to operate chmod 777 -R /home/user/CorsFace_install/OfflinePackage sudo apt-get install dpkg-dev cd /home/user/CorsFace_install/OfflinePackage/ # Generate dependency package relationships sudo dpkg-scanpackages archives/ /dev/null |gzip > Packages.gz cp Packages.gz archives/Packages.gz # Create sources.list to customize the location of offline sources echo "deb file:///home/user/CorsFace_install/OfflinePackage archives/" > sources.list # Package the contents of the whole project that need to be packaged to form a dependency installation of the project. Form offline package tar -cvf CorsFace.tar /home/user/CorsFace_install
Offline environment installation
In a new machine deployment environment
A shell script
# Copy project dependency package to user # Extract the file to the directory line of user tar xvf CorsFace.tar -C ./ cd CorsFace_install
# Set not to enter sudo command sudo cp nopasswdsudo /etc/sudoers.d/nopasswdsudo # Put the sources.list made above into the new version machine sudo cp /etc/apt/sources.list /etc/apt/sources.list.back sudo cp /home/user/CorsFace_install/sources.list /etc/apt/sources.list #Update source sudo apt-get update #Get package locally for installation sudo apt-get install mysql-server-5.6 #Copy the original sourcelists back sudo cp /etc/apt/sources.list.back /etc/apt/sources.list
Knowledge points involved
1. Understanding of apt get package dependency Manager
2. Agree on the installation path
3. Use shell to improve work speed
