A solenoid is the long coil of a circular loop of any conductor. the magnetic field lines inside the solenoid are parallel to each other just like in permanent magnet.

the magnetic field lines outside the solenoid are also similar to that of the permanent magnet. and hence we can assume the end from where the field lines are emerging as North pole and the en where field lines are merging as South pole.

When we bring a North pole of a bar magnet towards one side of the solenoid and if it repels the side of solenoid is North and if it attracts then the side of solenoid is South. The polarity of another side will be opposite.
