# My cheatsheet
This is my cheatsheet for setting up distribution using rpm. I am more experienced with distributions using dpkg, so I need this a little in the beginning.
## Installing Virtualbox guest additions
Start by installing dkms from [EPEL](https://fedoraproject.org/wiki/EPEL#How_can_I_use_these_extra_packages.3F).
```
rpm -i <package downloaded from EPEL link above>
yum install dkms
yum groupinstall "Development Tools"
yum install kernel-devel
```
Press HOST + D and cd to the mount point and run the Linux Additions installer.
## Enabling other repositories
For [EPEL](https://fedoraproject.org/wiki/EPEL) follow the first steps for Virtualbox guest additions installing above.
### RPMGforge
Download the [package](http://wiki.centos.org/AdditionalResources/Repositories/RPMForge#head-f0c3ecee3dbb407e4eed79a56ec0ae92d1398e01) and install it with
```
rpm -i <package>
```
### yum-plugin-priorities
Using multiple 3rd party repositories (EPEL, RPMforge) is dangerous so you must use priorities to be safe.
```
yum install yum-plugin-priorities
```
Ensure that it's enabled by looking at /etc/yum/pluginconf.d/priorities.conf . It should read
```
[main]
enabled=1
```
Now the plugin should be working and you must assign priorities.
Edit the following files:
```
/etc/yum/yum.repos.d/CentOS-Base.repo
/etc/yum/yum.repos.d/epel.repo
/etc/yum/yum.repos.d/epel-testing.repo
/etc/yum/yum.repos.d/rpmforge.repo
```
and add
```
priority=X
```
to end of every section where X is replaced with actual priority.
[CentOS wiki](http://wiki.centos.org/PackageManagement/Yum/Priorities) suggests the following priorities:
CentOS-Base: everything is priority=1 except contrib priority=2
Third party repositories (EPEL,rpmforge) should b > 10 and other should be more preferred than other. I used
epel 10 rpmforge 11
