Murphy, 31, finished his 10th season in the NBA on the Boston Celtics bench last season.
The Lakers will be Murphy's fifth team of his career. Murphy, a 6-foot-11 forward with 3-point range, averaged 14.5 points and nearly 11 rebounds for the Pacers in 2008-'08 and 2009-'10. With the Nets and Celtics a season ago, Murphy played sparingly in 35 games.
