One of Linux operations Learning Notes: Principles and Learning methods for operations and maintenance

has been using Linux, but never systematic study, starting from January 1 to study to the end of July 16, nearly seven months to learn, so that they have a new understanding of Linux, the old boy teacher's class is really good, the actual combat is very strong. Because only noon and night after 10 o'clock only time, so all the experiment is done on different computers, the text IP may be a bit of a problem, but should not affect the experiment. At the same time, in order to ensure the integrity of the notes, while taking notes, from the Internet also downloaded some pictures and content.

The first Zhang YUNWI principle: One, simple, easy-to-use, high-efficiency second, to make a backup 1, in order to roll back 2, so that the later than the change in the third, the minimum principle 1, the installation of the system to minimize 2, open service minimized 3, operation minimized

Rm-fr Test.txt more R, just delete the file, should be rm-f test.txt

4, landing minimized

Usually no need to log in without root, to use ordinary user login

5, the right to minimize 6, configuration parameters to be reasonable, do not maximize four, as far as possible to walk the road, the probability of a small problem (operation and maintenance requirements of stability) the second chapter of learning method One, in the use of memory two, through the case to summarize the technical points three, drawing to memorize knowledge points, so that knowledge becomes more simple, , contains the necessary content, to think of this command may have corresponding parameters directly show what we need five, learn to do a summary, to reach the conclusion of practice six, through examples or cases to remember the conclusion seven, try to use man to view the help, do not look at the second-hand information. The man command not only can view commands, but also view help for the process. Eight, with the data to speak, with the actual test to reach the conclusion nine, the deployment is correct, you can toss a point, so that the system error, improve the ability to solve the problem of ten, first to go through the road, then more flexible xi., good operating habits as a major event. 12. Some problems and suggestions for beginners to learn Linux operation and maintenance. See the Reference blog Note 203, re-goal, re-thinking, re-approach, re-practice, heavy habits, re-summary
