Linux learning experience Series 1

Linux learning experience Series 1-General Linux technology-Linux technology and application information. The following is a detailed description. Author: Richard Lee

The mood for this week was really good. I received the company's big news (winning several major projects). Today I went back to the company's previously desirable lab, and I felt very good, sometimes I am lucky to think about my work. I like my work very much. (the Environment and treatment are satisfactory. Haha, the university payment is worthwhile)

After work, I feel that I still lack a lot of things and have a stronger desire to learn than I have ever been. I hope that I can complete my tasks well and be appreciated by the leaders, maybe I'm a little eager to seek success. I feel bored after work every day. I 've been almost immersed in QQ chat and daze for several days. Fortunately, I found out in time (my own control capabilities are quite strong, so I decided not to fall, guard against arrogance and rashness, and learn with an open mind) and start charging myself-Linux for IT training for Rongxin foreign companies. I will share some of my experiences in the classroom with you (I will post some things that I have heard differently in the classroom on the technical level. If you have any questions, I hope you will advise)

Lesson 1: first of all, instructor Bai asked each of us to give a professional self-introduction of about five minutes (I am the first). It seems simple and contains a lot of skills, good self-introductions can help you during the interview. Next, Mr. Bai elaborated on our career development direction in detail. managers of enterprise MIS 2. integrators (of course, this is just a plan for our training). Here I would like to say a few more words, recently, many school girls asked me the same question: "What can we do after graduation?" In fact, everyone will encounter this question when I just graduated, but it depends on how you face it, you may find the answer to the following questions. For a while, I am addicted to technology (so far I am still a tech enthusiast). I can even do experiments without going to bed for a week, however, after talking to many business people who have been working for many years, he began to shake his mind and began to doubt his choice. Master Huang said: "Do not stick to a technology, learn a development model, and then draw the opposite picture, any technology is useless from application, "said Jiang." Don't be technical-only. You may be familiar with some management things as soon as you are about 30 years old"

Career thinking: What job do you want to do? What job can you do? What job do you need? Select one of the three (a good person told me when I graduated, thank you very much, at least until now I do not regret my choice) in fact, the enterprise selects the right talent based on their job requirements. Now I have a deep understanding of this.

Technical Thinking: Since the sophomore year, I have been in touch with the Internet. Since then, I firmly believe that technology is a dream (and I am still so persistent). However, in real life, sometimes it will shake your initial thoughts, life is a reality (as for whether it is material first or spiritual first, we will not discuss it here. The benevolent sees benevolence and the wise sees wisdom)

Some good words from teacher Bai and Mr. Huang (professional opinion ):
1. feel at ease when you encounter anything, and rely on yourself;

2. There are only successes and temporary failures;

3. just graduated students should not pay too much attention to their first salary: Bai's personal experience is the best proof of 50%-100%-an increase of or per year (reason: having slept for four hours in three days, don't worry, haha)-Now I have started my own business. I admire Bai's courage and imagine that I will make my own career one day;

4. Never give a problem to a leader. The leader wants multiple-choice questions and multiple-choice questions.

5. send emails to leaders to form good habits (Details determine success or failure). The format is as follows:

Title
Mr. Li:
Hello
1) Problem Description
2) solution:
1.
2.

6. Do not maximize your rights at any time, and minimize your risks to avoid unnecessary troubles.

Lesson 2: There are a lot of basic Linux commands that can be listed by Google or baidu, I will list some of the problems and solutions I encountered in my class with my classmates. I hope they will be useful to you (you can skip this course ).

1. When RHEL5 (redhat enterprise linux 5) is installed with a vmvm, the image mode cannot be entered.

Solution: the memory set by the Vm is too small, at least 256 MB.

2. cd etc General cd commands actually exist by default./That is, the current directory

3. /etc/init. d/rc5.d (my system default startup level is 5) files starting from S at system startup, and loading starts from small to large according to the numbers following S, it corresponds to the PID in the process displayed by Qilin PS.

4. I used to know a lot of Linux commands and should learn to make comprehensive use of them in actual work. For example, when configuring Apache, determine whether the service is started normally or not:

Ps-ef | grep httpd find PID
Netstat-anp | grep pID view port based on PID
Telnet XXX. XXXX. XXX. XXX port
Netstat-an | grep IP (port) check whether the port is LISTENING

5. In solaris and linux, h j k l on the key disk represents the top left, bottom right (in fact, you can use the direction keys in Linux)

6. flexible application of the Tab key can help you check for errors

It will be resumed next week.
