Creating an rpm package from the source.
We want to create a package from source code example. Download the source from the internet with wget:

# Wget http://www.example.org/dl/example-2.0.0.tar.gz

# Cp example-2.0.0.tar.gz / usr / src / redhat / SOURCE

# Cd / usr / src / redhat / SOURCE

# Tar xzf example-2.0.0.tar.gz

Check if there is within the directory Unpack the file '. Spec', which contains the specifications for the creation of the track, and copy it in / usr / src / redhat / SPEC:

Example.spec # cp / usr / src / redhat / SPEC / example.spec

If the file. Spec does not exist can be created. Finally, prepare the filling for the creation of the new rpm:

# Cd / usr / src / redhat

# Rpmbuild-bb SPECS / snort.spec
