Otu n'ime mkpa dị mkpa nke sistemụ Linux bụ ka a na-edobe ya mgbe niile site na iji patches ma ọ bụ mmelite kachasị ọhụrụ dị maka nkesa kwekọrọ.

N'ime edemede gara aga, anyị akọwala otu esi ahazi mmelite nchekwa akpaka na Debian/Ubuntu, n'isiokwu a, anyị ga-akọwa otu esi edozi nkesa CentOS/RHEL 7/6 gị iji melite ngwugwu nchekwa dị mkpa mgbe achọrọ ya.

Enwere ike ịhazi nkesa Linux ndị ọzọ n'otu ezinụlọ (Fedora ma ọ bụ Linux sayensị) n'otu aka ahụ.

Hazie mmelite nchekwa akpaaka na sistemụ CentOS/RHEL

Na CentOS/RHEL 7/6, ị ga-achọ ịwụnye ngwugwu ndị a:
