From Zero to Senior Ops Engineer: My Linux, Automation & High‑Availability Journey

I am Freeman, born in 1988 in Henan, now living in Shanghai for four years as a senior O2O operations engineer with five years of experience.

I maintain thousands of servers, am familiar with large‑scale website architectures, high‑availability clusters, and databases. I have extensive experience in business stability under high concurrency, have contributed to core automation projects, and follow developments in NoSQL, distributed storage, and big data.

Today I want to tell you my operations learning story.

Before stepping onto the operations path, I knew nothing about it. After becoming an ops engineer, I realized the repetitive nature of tasks, the chain reactions of cut‑overs and deployments, and the massive time and energy consumption that make the job painful.

At the beginning, I faced many unknown problems. Although colleagues helped, the solutions felt like a drop in the bucket and progress was slow.

Working under constant constraints, I realized that mastering operations requires systematic, comprehensive knowledge that cannot be acquired overnight.

This realization led to intense frustration and anxiety.

When faced with huge pressure and confusion, I understood that only self‑improvement can earn respect and that continuous learning is the key to freedom and value.

After analyzing my work in detail, I decided to enroll in a training institute (Ma Ge Education) for systematic study.

Embarking on the Quest to Master Linux

Like many of you, I started with almost zero foundation, having only skimmed a few pages of "Bird’s Linux Basics" and barely knowing how to type on a keyboard. I was an outsider learning automation, not the hot‑trend DevOps, but an electrical‑focused automation.

On the first day of Linux basics, I could keep up because it was mostly listening. From the second day onward, I fell behind, but the classroom atmosphere and peer collaboration helped me catch up through hands‑on labs.

I spent days listening in class, practicing after hours, asking classmates to debug, and staying up late to review material, creating a vicious cycle of fatigue and reduced focus. Eventually I found a late‑night schedule that worked for me.

When the course ended, the instructor waved goodbye, and I felt stunned—like a great movie ending before the climax. I had mastered less than 30% of the material.

Hero or Bear?

At that time I lacked confidence and didn’t dare look for a job, so I self‑studied videos at a nearby university with a few other classmates. After three months we split up, leaving me feeling down.

Life went on; we would hang out at a nearby café for Wi‑Fi, feeling a bit embarrassed because we rarely drank coffee.

While working with Nagios, services kept failing to start; after long troubleshooting I discovered the issue was an unclosed iptables rule. I was still a novice, and even now I sometimes feel that way, but after a day of studying the principles, the experiment finally succeeded.

The breakthrough boosted my confidence, leading me to learn load‑balancing, high‑availability clusters, MySQL backup and replication, and master‑slave setups.

I later found a small ops position in Zhengzhou, and after chatting with peers from Shanghai and Beijing about their superior environments, I decided to move to a big city with a few friends.

How to Stand Firm in the Smoke‑Free Battlefield of the Workplace?

Like many young people moving to big cities with mixed feelings, we faced fear of the unknown and low confidence.

Our group, though not highly skilled, shared interview experiences, asked senior peers for answers, and eventually secured jobs with salaries above 5‑6k, feeling much happier.

Teachers and alumni provided many interview questions, suggestions, and guidance, which was immensely helpful.

At the new company, the office was elegant, and I felt both excited and uneasy. The manager gave me an ops handbook, which reassured me because most of the content was familiar and detailed.

I moved closer to the company and university, often working extra hours, watching videos, and even studying on weekends alongside students preparing for graduate exams.

How to Get Ahead in the Workplace?

By the end of 2013, I had watched most videos two or three times, repeated experiments, and revisited core topics like web, MySQL, and high‑availability clusters, constantly taking notes and practicing.

When the company became less busy, I started preparing for new job interviews and professional etiquette, continuously polishing my skills.

After the Chinese New Year, I waited for the peak hiring season rather than rushing, reviewing my notes again.

Transformation or Falling into a Pit?

Eventually an O2O company contacted me. After a phone interview and several technical interviews covering principles, practice, details, and deep dives—ranging from web, databases, monitoring, load balancing, high‑availability, to large‑scale architecture and optimization—they gave me a problem to solve on the spot.

The interview excitement made me feel this was the company I wanted.

Negotiations with HR led to a salary comparable to a small company, and the O2O model seemed promising, so I accepted the offer.

My teacher once said life is about compromise and balance, a profound wisdom we should all experience and apply.

Acknowledgments

For those of you with zero foundation and a peripheral computer background, like me, who never had a programming mindset—my only C experience was sleeping through it—I want to say that I persisted, broke through, and earned recognition. I believe you can do even better and go farther.

Thanks to my teacher Ma Ge, the most powerful person I have met, who teaches with both virtue and skill, guiding many confused students toward a clear direction and helping them acquire a valuable skill in their youth.

We have not reached despair nor the brink of death; just keep learning. If there were a promise that mastering this would earn you a million, I bet you would learn even better.

Self‑driven motivation is essential. At a certain technical level, you must learn to research independently, because it’s not that others don’t want to help, but they may simply not know as much as you.

Words of Encouragement

Looking back, perseverance made everything less daunting than imagined. There were bitter moments, tears, sweat, gains, joy, growth, and increasing confidence. Every transformation is painful.

Breaking out of a cocoon is beautiful, but the struggle of piercing the hard shell is intense; if you can endure it, the butterfly’s beauty is worth it.

Life will reward you in the end, if you are worthy of seeing it. If you stop at the moment of breaking the cocoon and cannot endure the pain… you understand.

Congratulations on persisting this long; you are just beginning. The road ahead is still long, and I can only encourage you to keep going.

Just a few words of encouragement: keep going!

A Few Favorite Maxims

For my hardworking parents, I will keep fighting.

This world offers more than immediate hardships; there is poetry and distant horizons.

The greatest constant is change.

Walk the path you choose.
