I believe the type of rhyme used in this poem is masculine.
Masculine rhyme refers to a kind of rhyme where the last words in lines sound alike, and their final syllables are stressed. These words are usually monosyllabic (have only one syllable), or end in a stressed syllable. You can see in the poem here, that words such as alike and strike rhyme, as well as here and near in the first stanza.
Feminine rhyme means that the words don't end in a stressed syllable, which is rare in English. Slant rhyme refers to a type of rhyme which isn't 100% accurate, meaning that the words which 'rhyme' don't really sound the same. Free verse means there is no rhyme at all.
