Previously, windows to Linux were migrated using the normal exp and IMP methods. Logical backup is used to migrate data across physical structures and operating systems. SuchI believe many of my friends are doing this.
Today, we have a 50 GB database, which requires a Windows-heavy platform to be migrated to a Linux platform. In the past few days, I have been loo

Backup and Recovery
For example, we want to back up the MySQL already exists in the database named Linux, to use the command mysqldump
The command format is as follows:
[Root@linuxsir01 root]# mysqldump-u root-p linux >/root/linux.sqlEnter Password: Enter the password for the database here
For example, the AAA library created by the previous example is backed

Third, when the LVM structure is corrupted, the backup information is also damaged (for 1, 6 of common failures):
This is the real technical problem, when the LVM structure and its backup information is corrupted, all the LV Fragment index information is all lost, the work to do is to retrieve the LV extents information for each VDI.
Xen VDI is based on the VHD format developed jointly by Connectix and Microsoft, typically with a streamlined growth model

Method 2:
The first method is to restore the password of another Mysql database without such a known password. How can we recover the database? We use a method described in the Mysql Chinese Reference Manual, which involves several steps:
1: Send the kill command to the mysqld server to disable the mysqld server (not kill-9). The files that store the process ID are usually located in the directory of the MYSQL database.
Killall-TERM mysqld // you must be a UNI
First, it is the first step to build an experimental environment before doing the experiment, and the next is to do the experiment.The following is my experimental environment: prepare a virtual machine with a Linux system (I use the Linux6 version of the virtual machine), and the system to have two disks, that is to add a disk. The newly added disk will be partitioned and formatted before the MBR sector failure can be simulated. However, before you p

Git is currently a popular distributed project versioning system, compared to SVN has a great advantage, yesterday was thinking that you should make good use of git, so I think you can use git version fallback, etc. to do a simple project automatic backup and recovery functions. This allows you to use GIT to do project versioning and to use Git as a backup. This makes it easy to migrate, back up, and so on.Features and implementations are really simpl
