Minimal installation of Linux

When installing the Linux operating system, it is a good practice to follow the principle of minimizing the installation, which means that you do not need or determine whether the required packages are not installed. Minimizing the installation can be a measure of weight for the system, but more importantly it can improve system security. This article takes CentOS6.6 as an example to illustrate the steps to minimize the installation of a Linux operating system. In the CentOS6.6 package selection interface before the installation process is no longer described, directly into the package selection interface, see the following:

After the installation is complete, if you find that some of the package groups are not selected (it may not be the system you installed), you can use the Yum groupinstall "Desktop" "X Window System"-y command to install the package group. After completing the above installation, there may still be some common packages that are not installed, so you can use Yum to complete the installation as needed. For example, some common installation packages: Yum install Lrzsz tree nmap sysstat dos2unix-y and so on. If the system needs to update patches, you can execute the Yum Update command. In the absence of absolute certainty, you should never use Yum's software uninstall feature, which may remove dependencies on the software and cause unexpected occurrences.
