fig. 3 is a schematic structural diagram of a database migration system according to an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, the database migration method for migrating a database from a source device to a target device includes the following steps S1 to S6.
And S1, displaying an input interface for the user to input the migration parameters in the migration process. The migration parameters comprise source end information and target end information, the source end information comprises an equipment identification code and a port of the source end equipment, a name of a database to be migrated, a user name of the database and an access password of the database, and the target end information comprises an equipment identification code and a port of the target end equipment, a name of the database to be migrated, a user name of the database and an access password of the database.
Therefore, a front-end HTML page to be displayed to the user needs to be constructed, and the page is mainly used for selecting or filling in database information of the source end and the target end, including an IP address, a port, a database name, a table name, a database user and a database password. Where the database name and table name may replace all databases or tables with a number. In addition, the page needs to define a display module DIV for displaying the migration log and the migration progress in real time.
S2, obtaining migration parameters, wherein the migration parameters comprise source end information and target end information.
And S3, migrating the database from the source device to the target device according to the migration parameters.
Taking a relatively common MySQL as an example for specific description, the method comprises the following processes:
a) and connecting the target end database with the source end database by using a pymysql module according to the information filled in the front end HTML page.
b) And connecting a target end machine by using SSH, exporting the database data to be migrated, which is specified in HTML by a user, by using a mysqldump command, and storing the database data as a text type file.
c) The method is mainly used for backing up data, preventing the possibility of data loss caused by the mistaken input of a user and facilitating the timely rollback of the mistaken input of the user.
d) And importing the text file exported in the last step into a target end database specified in an HTML page by the user by using a source command.
And S4, acquiring and archiving the migration log in the migration process.
Taking a relatively common MySQL as an example to concretely explain how the operation is implemented:
a) writing ajax function for acquiring log output in real time
The function is mainly used for acquiring log information in the migration process in real time, and continuously loading the latest log information in a display module DIV defined in the first-step front-end HTML.
b) Archiving of functions using Python log output function at backend
For the whole migration process, the log is set in a modularized mode by using the logging module of python, so that the log can be displayed on a page in real time, the filing of the migration log can be guaranteed, and the detailed process of the migration record can be conveniently inquired at any time later.
S5, checking the row number of the database before and after the migration to judge whether the data of the database after the migration is matched.
And checking the number of rows of the migrated database, and judging whether the migrated data is matched with the data before migration, wherein the specific step is that pymyql is used for connecting the source end database and the target end database, and the migrated data is circularly compared according to the table name in the table name and the table name in the target end database. The comparison steps are as follows:
a) and collecting the tables by using the analyze statement, and acquiring the statistical information of the latest table row number.
b) Acquiring the line number of the table from an information _ schema table, judging whether the line number of the table of the source end database is consistent with the line number of the table of the target end database, if so, judging that the migration is successful, and if not, prompting an exception four after exiting: the data consistency check fails;
and repeating the previous step for traversing and judging the tables in the target end database after migration according to the table names.
S6, integrating the archived migration log into the migrated database.
The process is realized by a self-defined audit information function.
At this moment, an audit function needs to be defined for integrating and recording the information of the migration, and the integration process is to store log information, database information of a source end and database information of a target end in the migration process in a database of the target end after the migration. By the operation, the specific log information of the migration is stored in the database, so that the record can be conveniently checked in the future.
As an optional optimized implementation manner, while the step S3 is performed, the following error prompt step S7 is provided.
And S7, an error prompting step, wherein if errors occur during data migration, the error category is displayed according to the preset error classification.
As shown in FIG. 2, the specific steps of error prompt are S7-1 to S7-4:
s7-1, checking the data size of the table and the data size of the index of the database to be migrated, and judging whether the storage space of the target end equipment is larger than or equal to the sum of the data size of the table and the data size of the index, if so, proceeding the next step, if not, stopping migration and prompting an exception after quitting: the target server has insufficient space and cannot be migrated. In this embodiment, the storage space is preferably greater than or equal to twice the sum of the data size of the table and the data size of the index, so that the migration effect is good, and the storage space can be reserved for subsequent log files.
S7-2, checking whether the export process is abnormal, if so, proceeding to the next step, if not, stopping migration, exiting and prompting an abnormality II: the source database derives errors.
S7-3, checking whether the database to be imported exists, if not, directly building a new database by taking the database to be imported as the name and entering the next step, if so, renaming the database to be different new names, building a new database by taking the database to be imported as the name and entering the next step;
s7-4, checking whether an exception exists in the import process, if so, checking the line number of the database before and after migration and judging whether the data of the database after migration are matched, if so, stopping migration and prompting an exception III after exiting: and the target-side database imports errors.
The database migration apparatus provided by the embodiment of the present invention will be described in detail below.
A database migration apparatus comprising a memory and a processor, the memory having stored thereon a computer program that runs on the processor, characterized in that: a method of implementing database migration when a computer program is executed by a processor, the method comprising the steps of:
