3. Appendix--- apt-get principle
As we all know, under the Linux operating system, it is very convenient to use apt-get to install software. Just one sudo apt-get install software name; The most important thing is that it can solve all kinds of complex dependencies, so that you don't have to worry about it, and before apt-get, use dpkg or earlier ./configure; make; make install to install the software is really unimaginable, after installing software A, it prompts you to install software B, and finally completes the installation, and prompts to install software C. . . All kinds of entanglements! Therefore, apt is an advanced package management tool that greatly facilitates the majority of Linux users and lowers the entry threshold for Linux users. Whenever a command is executed to install or update software, or to update a software source, apt will visit the address in /etc/apt/sources.list and find the package information of the corresponding system on the website, such as the operating system is ubuntu and the website is deb http://mirrors.163.com/ubuntu/ precise main restricted universe Multiverse NetEase, then when we execute the installation command, he will access the http://mirrors.163.com/ubuntu/dists/lucid/main/binary-i386/ packages.gz, this file is a list of packages and their dependencies on the server, and has been compressed with gzip. apt-get update uses this list to determine which supplementary packages are available and their content is saved in /var/lib/apt/lists, and by accessing this list to determine whether the software is installed, whether it is the latest version, whether the dependencies are met, and then determine whether the content is to be updated, and the installation process is mainly done by dpkg.
In general, apt is a management tool that tends to be downloaded. |
