Installing VMWare on Redhat Enterprise |
|
|
Nowadays, virtualization is a solution which is interested by many IT manager. By converting existing system to virtual, you can save lot of money from buying new hardware every year, avoid hardware conflicts when you move virtual to another computer, etc. But when you convert system to virtual, you still need OS to run virtual software (VMware, Virtual PC, etc). The best practice is to have Linux operationg system running on host so that you won’t have to pay an additional license. Then, you can have whatever OS you want on virtual. For virtual software, VMWare is the one I recommend to try. There are some free licenses if you want to try. Like VMWare Server, you can have many virtual on a PC and you can connect to manage your virtuals remotely by using VMWare Server Console. This article shows how to install VMWare Server on Redhat Enterprise. |

how to install RPM package |

rpm -i — What does it do?
Of the many things RPM can do, probably the one that people think of first is the installation of software. As mentioned earlier, installing new software is a complex, error-prone job. RPM turns that process into a single command.
rpm -i (--install is equivalent) installs software that's been packaged into an RPM package file. It does this by:
- Performing dependency checks.
- Checking for conflicts.
- Performing any tasks required before the install.
- Deciding what to do with config files.
- Unpacking files from the package and putting them in the proper place.
- Performing any tasks required after the install.
- Keeping track of what it did.
