Do you own a dedicated server running a Debian or any other Linux distributions ? If yes, then you must be familiar with the command apt-get. People using Linux distributions like ubuntu server edition should know about such commands as these commands will help to make things easier.
Apt-get is a very usual command normally used to install and uninstall softwares. An example using the apt-get command is shown below:
# apt-get install packagename
Whenever a package or a software is installed on the server using the apt-get command, it holds default configuration files and when the package or software is in use it creates a different configuration file that includes custom information. In order to make it suit your requirements, you can adjust the configuration of that file manually. Most of the times, several situations will occur where you might make a mistake and due to that the software will stop functioning. In such case, if you have a deep knowledge about the file, you can fix the issue in the configuration file. This is the main reason why offsite backups are necessary whenever you make changes to any of your server files.
In case, if your forget to backup your files or don’t know how to fix the issue, you can always reconfigure the package. Reconfiguring the installed debian package will restore the original configuration when the package was installed. To reconfigure the installed package simply enter the following command:
# dpkg-reconfigure packagename
Using the above command will restore all the configuration settings. Once the restoration is completed the software installed on your web hosting server will start functioning properly however, the previous changes made to the configuration file will be lost.
