MySQL шпаргалки (основа взята отсюда: https://habrahabr.ru/post/105954/ )

#Работа с бекапами

NB: пароль в командной строке лучше не указывать, если это не крон-like задача, конечно. Ключ -p запрашивает ввод пароля поссле ввода команды.

Делаем бекап

mysqldump -u USER -pPASSWORD DATABASE > /path/to/file/dump.sql

###Создаём структуру базы без данных mysqldump --no-data - u USER -pPASSWORD DATABASE > /path/to/file/schema.sql

andrey-str / KVM OSX Guest 10.11 (El Capitan) with Clover.md
Created September 12, 2016 23:36 — forked from gordonturner/KVM OSX Guest 10.11 (El Capitan) with Clover.md

KVM OSX Guest 10.11 (El Capitan) with Clover

  • Some notes about this approach:
    • An OSX Installer USB drive for Install OS X El Capitan is created
    • Clover is then installed on the USB drive
    • Clover Configurator is then run on the USB drive
    • The USB drive contents are copied to the VM host
    • VNC is used to connect to the guest UI
  • The qxl virtual video device is used (part of the standard kvm qemu install)
