Configuration of Debian Linux system after installation __linux

Set Source
Because most sources are not very stable, that is, a certain degree of timeliness, and the speed of download is not necessarily guaranteed, so you can install and use Apt-spy to automatically test which source download speed fastest, and automatically write the fastest source to the configuration file. For details on Apt-spy, see the comments at the end of the article. Set temporary source

# Enter the following command in the Terminal of root permission
vi/etc/apt/sources.list
# Add the following line to Sources.list:
deb http:// Http.us.debian.org/debian Stable Main

Update the package list and install Apt-spy

# Enter the following command in Terminal under root permission, update the package list and install Apt-spy
apt-get update
apt-get install Apt-spy

Automatically download lists and use Apt-spy to test the fastest source

# Enter the following command in the Terminal under root permission
#-D Distribution Select the release version of Debian, such as stable. In addition to upgrades, you must use this parameter
#-a area to select areas for testing, such as AISA.
#-C config Specifies the configuration file.
apt-spy update
apt-spy-d stable-a asia-t 3

View the generated configuration file

# Enter the following command in the Terminal under root permission
cat/etc/apt/sources.list.d/apt-apt.list

Delete the temporary source you just set up, as follows

/etc/apt/sources.list

Update package List

# Enter the following command in the Terminal under root permission
apt-get update

Install the basic development environment

# Enter the following command in the Terminal under root permission
# Install the C + + development package  
Apt-get install build-essential  
# install Vim editor (personal hobby)  
Apt-get Install VIM  
# If you are installing a system in a virtual machine, in general, you will need to have the system pre-installed made and the Linux header when installing Vm_tools. (Make or GCC has been installed in the build-essential package, skip)  
Apt-get Install linux-headers-$ (uname-r)  
# installation Vm_tools If the permission is still not enough to be denied under root permission, you can enter the following command in the appropriate directory to elevate the permissions  
chmod +x. Install  
# Or  
chmod 777./install
