安楽 (あんらく) is a Sino-Japanese な-adjective/noun meaning 'ease, comfort, peace.' The adverbial 安楽に describes the manner of 暮らす ('live, get by'). 暮らす is the verb of daily existence — distinct from 住む ('reside in a place') in that 暮らす captures the rhythm and quality of life, not just where one is. ~ている marks the ongoing state of living comfortably. The phrase has a slightly idealized, idyllic flavor; everyday speech might say 楽に暮らしている.
