Laruence's Linux Private food study Note 1

Take a note of laruence's Linux Private food study-Linux general technology-Linux technology and application information. The following is a detailed description. I finally bought "laruence's Linux Private food-basic learning", but it was more than a month ago. Finally, I opened this book, this is really a hit-every time I look for online recruitment information, the words "linux administrator" always look like a thorn in my throat. It hurts! So the first determination of the New Year was to solve this book within a month! That is, swallow should also swallow it-exaggerated!

Starting from chapter 1, we can't help seeing Chapter 3-because it's all about theory, it's difficult. As a result, Chapter 3 only reads one section and goes to Chapter 2: RPM and SRPM suite hypervisor. This is because when you run the command to install VMTool (rpm-ivh name) and query again (rpm-q name), the system prompts that the installation is not successful. This problem has not been solved in linux enterprise 5. But it's done on linux enterprise 4!

When I solved the CVS problem for my colleagues, I found that the useradd command was not available, so I transferred it to Chapter 14th: linux Account and identity management. But it still does not work when using the example: "useradd username" prompts no useradd command:

[Root @ localhost ~] # Useradd echoshu
Bash: useradd: command not found

Find the following solution:

[Root @ localhost ~] # Vi ~ /. Bashrc
Add export PATH =$ {PATH}:/sbin:/usr/sbin
[Root @ localhost ~] # Source ~ /. Bashrc

No, so I learned Chapter 1: vi text processor.

This is the result of today. A good start is half the success. Come on. Fighting.
