How to learn Linux System Administration
Read one of my favorites “Book Linux one in all”. Only reading is not sufficient for a job or any freelancing work. you have to earn huge practical knowledge. because the Linux system administration is very sensitive work. if you missed something you may hunter from the hacker. then you will lose all the data and website files. so you must have to very practical about this. I started my career as a web developer. web development knowledge helps me in 1 step. I know about security and basic security. then I just gather knowledge how to configure the Linux and secure the website and server. However, Download the book as well as watch videos from youtube. The best way is to buy the latest premium course. I followed some youtube channels for Basic Linux. But now the videos are backdated. I prefer you to find out a latest playlist.

My Opnion About Linux Administration
If you learn Linux to earn money, that’s good. but remember you have to be passionate about your work. Linux system is a very advanced course. there you just need some basic knowledge about computers and the internet. i.e: you have to know how the internet work, what is a website, the website backend-font end, operating system, computer memory, processor, and storage in detail. Also, you have to know basic cybersecurity. to me, Linux server/OS is very easy than the web development or digital marketing. but It is very sensitive work. you would have to ensure 100% security in Linux.
