Different education systems differ, however
At school you would take maths and physics courses, at least covering calculus.
As an undergraduate, taking (or majoring in) physics. Also probably doing some more maths and perhaps some astrophysics courses.
As a postgraduate doing Masters study in astrophysics leading to PhD research in astrophysics. By now you could say that you are an astrophysicist.
Then working at a university or similar institute.
This makes it all sound easy, but I think I should add a warning. Getting a permanent (research) position at a university or similar institute in astronomy is highly competitive, and to get there takes a combination of hard work, high competence, high motivation, and luck. Many highly competent people end up moving out of astronomy and use their skills elsewhere, for the simple reason that society does not spend enough money on astronomy to employ all highly competent people who want to spend their life on astronomy.
The main way into astrophysics is - as James K outlines in his answer well - to study physics with an emphasis on astrophysics or astronomy. The entry into these academic careers are easier for those who already are interested in / good at physics and especially maths. Typically one continues after the BSc with a masters and a PhD in a field of your (astrophysical, planetary, solar system, astronomical,...) interest, usually at a university, observatory or other research institutes with interests in these fields. After a PhD one continues as post-grad and/or research fellow at research institutions.
While studying physics is the most straight forward way into astrophysics, there are many paths. Some others include:
There are people who did a BSc and/or MSc in Engineering subjects (rocket science of course being a favourite one), and then changing into astrophysics via instrumentation - or just simply switching to astrophysics directly in their PhD.
Another popular approach is via geo sciences, especially geophysics, geology, etc. From where knowledge and methods can be applied and generalized to other bodies in the solar system.
You can get there from a mathematical or computer science background while looking for applications... The necessary simulations in theoretical (astro)physics and especially cosmology are far from easy math and simple algorithms, so a sound mathematical and algorithmic understanding will get you very far there.
Generally, it's science. And you can only really do science, and be good at it if you love what you do. That includes learning, being curious, inventing, combining and applying methods and approaches on a problem and generally being not shy of mathematics is somewhat a pre-requisite.
Lastly a word of caution - gerrit phrased it well on a comment to another answer: Getting a permanent (research) position at a university or similar institute in astronomy is highly competitive, and to get there takes a combination of hard work, high competence, high motivation, and luck. Many highly competent people end up moving out of astronomy and use their skills elsewhere, for the simple reason that society does not spend enough money on astronomy to employ all highly competent people who want to spend their life on astronomy.
Other answers have mentioned engineering as a possible pathway, however, they seem to have had mostly instrumentation in mind, which is why I would like to specifically point out software engineering.
I work at a theoretical institute and a very large proportion of the work done here is based around simulations. Unfortunately, however, in my experience many astrophysicists write their first lines of serious code when they start their PhD.
So programming/software engineering classes are definitely something to consider. Even if you do not want to become a simulation specialist. And it could also be possible to switch from something like a software engineering Master's to an astrophysics PhD (although as of yet, as pointed out by @RobJeffries in a comment, this seems uncommon).
I did much more programming in my physics Master's than the average student and still I spent countless hours at the beginning of my PhD writing very bad code that I just ended up throwing away in the end, while the mathematics education I received was easily sufficient.
If it isn't a duplicate, then neither is this!
My career path:3-year Bachelor's degree in "Physics with Astrophysics"; PhD in X-ray astronomy; 5-years as a postdoctoral research assistant (two separate posts); got a lectureship at a UK university doing teaching and research in Physics and Astrophysics.
This is reasonably typical. These days, the content of the first degree is not so important - Physics, Astrophysics, Applied Maths all would be ok. "Astronomy" would put you at a disadvantage, since the implication is a non-physical, observational approach; but you would have to look at the course content.
A masters degree or 4-year first degree is usually necessary to get onto PhD programmes in the best places (this has changed since my day). Doing your PhD quickly and writing several publications is usually necessary to proceed any further.
The normal next step is to get a postdoctoral position; preferably somewhere other than your PhD institute. Then after 2-3 years of producing more research papers (2-3 per year), you could try for personal research fellowships. If you can get one of these, or perhaps a second/third postdoc position, and your research is going well and is productive, then there is a few year window in which to get into a tenured or tenure-track position. Getting some teaching experience at this stage is probably important.
For someone on a "normal" career path, it would be unusual to get a University position before the age of 30 (i.e. 8-9 years after your first degree). The large majority of people with a PhD in Astrophysics do not end up doing that for a living.
I came across this video a few days ago that I thought gave a nice, quick perspective on one person's path: https://www.youtube.com/watch?v=n8cEZM1lN5g.
Matt, the host, discusses how he turned his interest in the workings of the universe into a physics undergrad degree, followed by a grad program at the NASA Space Telescope Science Institute, and then a couple of post-doctorate programs, finally becoming a professor of astrophysics.
It seems that higher education with a focus on math and physics is the most predictable path toward an astrophysics career.
