Learning OpenStack (3): Devstack Screen usage tips

Devstack Environment, OpenStack runs in a screen with each service running in a window. I summarize a few tips:

0. Note that you need to use screen to start the user to do a bit

1. View all screen:screen-list opened by the current user

[Email protected]:~/devstack$ screen-list
There is a screens on:
9606.stack (12/12/2014 11:22:54 AM) (Detached)
1 Socket in/var/run/screen/s-s1.

2. Screen attach:screen-r <screen ID, such as 9606> in (note: OpenStack rejoin-stack.sh also calls this command to reattach OpenStack)

(Playing * is the current window)

3. Screen dettach:screen-d

4. Move to the next Window:crtl + A + N

5. Move to the previous Window:crtl + A + p

6. Jump directly to a window at 0, such as the 7th in: CRTL + A + 7

7. Jump directly to the 10th window, such as 17th:CRTL + A + ', enter a

8. Scroll through screen window: Start scrolling mode CTRL + [, then use up or down to scroll the screen, press CTRL +] to exit scrolling mode

9. Restart a cinder service:

(1) CRTL + A + <n, e.g. C-vol window >

(2) CRTL + C, kill the process

(3) Press up ARROW to appear the previously run command, the input is restart C-vol service

10. Press CRTL + A, wait a second, and then press the (SHIFT + key) to display a list of all windows in screen (four keys are not working continuously:))

11. Default all screen shortcut keys
