Old boy prompt:

1. Based on experience, the installation package should be minimized, that is, no installation is required or not sure whether or not required, so as to maximize system security.

2. If some package groups are not selected during the installation process, you can add the uninstalled package groups as follows:

Yum groupinstall "compatibility libraries" base "" development tools"

Yum groupinstall "debugging tools" "dial-up networking support"

You can view the installed components in the yum groupinfo package group.

3. Check the selected package when logging on to the system after installing 6.5:

Yum grouplist:

Installed groups:

Base

Compatibility Libraries

Debugging tools

Development Tools

E-mail Server

Graphical Administration Tools

Hardware Monitoring utilities

Legacy UNIX compatibility

Networking tools

Performance Tools

Perl support

Scientific support

Security Tools

* In addition to the selected software packages, some additional software packages are installed by default.

Note: Do not use yumThe deletion function of software will delete related dependencies, resulting in unexpected problems.

(2) Install system supplemental Installation tool command

Some basic tools are not installed after the system is installed. you can install Yum as needed. For example:
Yum install tree NMAP sysstat lrzsz dos2unix-y

If you need to update the patch, execute

Yum update
