If you use the Debian package manager to manage Linux software, you should learn more about the principles of the Debian repository, which will make it easier to manage Debian software using Linux commands.
The Debian software library used for Linux package management, Debian provides the installation source for the package. The Debian Manager will automatically find the dependencies of the library and the Debian package. If you don't have a Debian software library management system, it's an annoyance to resolve the dependencies of these Debian packages.
According to the current Linux distribution, the main Debian software library management system is Debian's software library management system, mainly used on Debian, Ubuntu and its Linux derivative systems, such as Linux Mint; Debian software library management system uses the default Debian package. format. Debian uses .deb. These Debian packages are software and metadata compression and archives. Debian metadata provides information about the version of the software and the dependencies of the Debian package.
However, the Debian package database is easily confused with the Debian software library. Although these Debian packages can make the job easier through Debian software library management, these Debian packages have another database at the same time. This means that there can be multiple sources of information for the Debian package: the Debian package database and the Debian software library database.
The Debian package database is installed by Debian software. The most important source of information in Linux systems. The Debian package database retrieves the currently installed Debian software from the server. The Debian package file is usually a rich Debian document and a source of information used by Debian software, which is very useful for dependencies between Linux system Debian packages.
On a Debian-based Linux server, use the dpkg command. For example, the dpkg -L command can read the Debian package list, or the rpm -ql command shows which files are included in a Debian package.
Most of us use Windows system very well, but for Linux system, many people have never used it, so this article is designed to help everyone install Debian operating system, Debian is a free operating system, the most important part is called kernel (kernel) . Linux is a software originally created by Linus Torvalds and currently maintained by thousands of programmers around the world. Debian brings over 51,000 packages (for easy installation on your machine, these packages are already available). Compiled into a convenient format), an package manager (APT), and other tools that help you manage thousands of packages on thousands of computers. The process is as simple as installing an application.
Debian systemAfter downloading the image, make a U disk boot disk and boot from the USB disk.
Tools/raw materials
Mirror
U disk boot disk
Method / Step 11 Select Graphical installation on the boot screen to enter the installation process.
1 Select the language interface, select Chinese
2 Tips Although it is kind, but I saw a garbled during the installation process, which is the following picture, directly select, the next step.
3 regional choice, choose China.
1 host name, fill in debian.
2 domain name can be left blank, directly next.
1 Set the root password to root and the super administrator account.
2 create a new user, this is just a nickname, not the user name when logging in, you can fill in according to your preferences.
We set it to debian
3 This stuff is the user name when logging in, pay more attention when setting, and must remember.
User configuration here is debian
4 Set the user password 1234.
1 Next, the disk is partitioned, I use the virtual machine, but the method is the same.
2 If you have a free partition, it is recommended to use the installer for automatic partitioning. Of course, you can also manually partition.
If you are automatically partitioning, if the newcomer recommends "put all the files in the same partition", if you have experience, adjust it according to your preferences.
3 manual partition, you must remember to mount / root directory, otherwise it will report an error.
The Swap partition (swap partition) is recommended to be twice the size of physical memory. For example, my actual memory is 2G, and swap is 4G.
Save the partition table after completing the adjustment.
It is important to remember to mount the partition number of the root directory / to facilitate the installation of grub.
4 elections are.
1 For the software installation, since the tutorial is written as a pure installation, it must be purely headed. For the software package popularity survey, you can not participate.
2 Do not scan other DVDs, do not use network mirroring.
I did a tutorial on DVD-1 full image for speed. If it is a network installation image, I will not have the following prompt. For network mirroring sites, I also choose not to use it.
If you have to choose, choose ftp.cn.debian.org in Asia's China.
3 select the software package to install, of course, all are not selected, the need to install manually behind, the desktop environment installed here will connect to the security server to update the kernel, then the speed is really waiting to cry. Select only desktop xface and sshserver
1 After the installation is complete, configure Grub. If you don't want to replace the MBR with Grub, you can choose to enter it manually.
Then enter the filesystem of the mount root directory you configured earlier. Like I used /sda1, enter /dev/sda1 here. (No special treatment, ignore directly, continue by default)
2 After the installation is complete, unplug the boot USB flash drive and click Continue.
Normal entry into Grub should be like this. If the graphical interface is not installed, the default interface is really ugly. GRUB ignore
2 Press Enter directly to enter Debian. After the system is loaded, if the following interface appears, the startup is successful.
We installed a graphical interface, automatically enter the graphical interface, enter the username and password to login
3 Enter root after login, enter the set super administrator password after password, and enter the system with super administrator privileges.
