Hướng dẫn frm and ibd files in mysql - các tệp frm và ibd trong mysql

Tôi thực sự đánh giá cao ECD. Những gì làm việc cho tôi:

1.- Tôi đã có một bản sao lưu của cơ sở một vài tháng trước, điều này đã giúp tôi nâng bản sao lưu này trong XAMPP trong Windows 10 và tạo các bảng để có cấu trúc (Cấu hình: Windows 10, XAMPP-Windows-X64-7.1.30- 5-VC14) Tệp cấu hình MySQL My.ini ở cuối I had a backup of the base a few months ago this helped me to lift this backup in xampp in Windows 10 and create the tables to have the structure (configuration: Windows 10, xampp-windows-x64-7.1.30-5-VC14) mysql my.ini configuration file at the end

NOTE: Some tables did not have ROW_FORMAT = COMPACT, so I went to operations on each 
    table and changed it manually.
    (If I did not do that, an error appeared and I did not let the import).

NOTE2: I had the backup of months ago but it should also work by first recovering 
    the structure of the .frm files in case of not having a backup at hand.
    (You can try this link:
    https://www.percona.com/blog/2014/01/02/recover-table-structure-frm-files-mysql- 
    utilities/)

2.- Có cơ sở dữ liệu cũ, tôi đã tiến hành thực hiện không gian bảng thay đổi XXX cho mỗi bảng trong cơ sở dữ liệu mà tôi muốn khôi phục, sau đó các tệp .ibd của thư mục dữ liệu trong C: / XAMPP / MySQL / Data / System đã bị xóa (trong trường hợp này là con đường này) Having the old database up, I proceeded to execute alter table xxx discard tablespace for each table in the database that I wanted to recover, then the .ibd files of the data folder in C: / xampp / mysql / data / system had been deleted (in this case it is this path)

3.- Tôi đã tiến hành sao chép các tệp .ibd từ cơ sở dữ liệu tôi muốn khôi phục vào thư mục XAMPP của cơ sở dữ liệu cũ I proceeded to copy the .ibd files from the database I wanted to recover to the xampp folder of the old database

4.- Có các tệp được sao chép, chạy: thay đổi không gian bảng nhập bảng xxx cho mỗi bảng trong cơ sở dữ liệu, cảnh báo sẽ xuất hiện nhưng chúng tôi sẽ bỏ qua nó, dữ liệu sẽ được tải trong bảng và có thể được xuất sau. Having the files copied, run: alter table xxx import tablespace For each table in the database, a warning will appear but we will ignore it, the data will be loaded in the table and can be exported later.

5.- Xuất toàn bộ cơ sở dữ liệu vào một tệp SQL và tiến hành xây dựng nó trong sản xuất và thành công! Export the entire database into an sql file and proceed to build it in production and success!

# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# You can copy this file to
# C:/xampp/mysql/bin/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is C:/xampp/mysql/data) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients
[client] 
# password       = your_password 
port            = 3306 
socket          = "C:/xampp/mysql/mysql.sock"


# Here follows entries for some specific programs 

# The MySQL server

# Change here for bind listening

# Where do all the plugins live
plugin_dir = "C:/xampp/mysql/lib/plugin/" 

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)
# binary logging is required for replication
# log-bin deactivated by default since XAMPP 1.4.11
#log-bin=mysql-bin

# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id   = 1

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=,
#    MASTER_USER=, MASTER_PASSWORD= ;
#
#    where you replace , ,  by quoted strings and
#     by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  
#
# binary logging - not required for slaves, but recommended
#log-bin=mysql-bin

Tôi hy vọng nó sẽ giúp một người có tình huống này, liên quan.
