(this question has two possible meanings; both are responded to, below)
(1) To sign-up for tickets for a Grand Slam event, spectators must contact the venue's ticket office, or buy tickets from a legitimate reseller, some of which may be found online. Some Grand Slam events give past ticket holders a chance to buy tickets for the following season(s). Some events, such as Wimbledon, sell a limited number of "debentures" (i.e., very expensive stocks, which, in this case, are traded on the London (Stock) Market) to anyone who can afford it, but there are strict limitations to owning such debentures.
(2) Professional tennis players may sign-up for a Grand Slam event by requesting a "bye", seeding, or entry into the event, usually through their agent or manager. Since Grand Slam events only have room for 128 players in the men's and women's singles, only a limited number can play.
Each of the four Grand Slam tournaments has its own draw, so it's possible for a player to qualify for one or more, but not all.
For each tournament, there are three major ways to enter. Some players are seeded; these are generally the top-ranked players in the world, although occasionally a player whose ranking is a bit lower but who is expected to do well at a particular tournament may also receive a seed. The most obvious example would be a clay court specialist at the French Open, the only tournament of the four that uses clay courts.
Other players receive at-large bids; these work basically the same way as the seeds, except that they're provided to slightly lower-ranked players. In both cases, the tournament organizers choose which players enter by these methods.
The last way in is through qualifying. Prior to the main tournament, qualifying tournaments are held for amateurs or lower-ranked professional players who don't expect to get a seed or at-large bid, but would still like to play. Winning a designated qualifying tournament earns the player an automatic entry into the main tournament, though qualifiers are usually placed against top-seeded players in the first round, so it's not too common for them to last long in the tournament.
A true Grand Slam in tennis is when a player wins all four Grand Slam tournaments in the same year. Otherwise it is just a career Grand Slam, and not a true Grand Slam.
