How does one back up mySQL databases in linux?

Method 1: suitable for mysql databases in all formats. it is regularly executed by exporting and importing a script to the database:
1. export the entire database mysqldump-u user name-p database name> exported file name mysqldump-u wcnc-p smgp_1__wcnc>/storage path/wcnc. SQL
2. export a table mysqldump-u user name-p database name table name> exported file name mysqldump-u wcnc-p smgp_rj_wcnc users>/storage path/wcnc_users. SQL
3. export a database structure mysqldump-u wcnc-p-d -- add-drop-table smgp_rj_wcnc>/storage path/wcnc_db. SQL
Definition:
-D no data
-- Add-drop-table: add a drop table before each create statement.
4. run the source command to import the database to the mysql database console:
For example, mysql-u root-p mysql> use database

Method 2: for mysql data tables in the format of MyISAM
Assume that the data file is in/var/lib/mysql
Write a script directly.
Cp-r/var/lib/mysql/directory to which the backup is saved

Remote Backup uses rsync increments or regular full backup.

Who can give me a script for MYSQL automatic backup?

Maybe you won't use it.

You can put this script into crontab and execute it once every morning to automatically back up data.

This script can be executed only once a day, and only the backups of the last five days are retained on the server.

Code:

#! /Bin/bash
# This is a ShellScript For Auto DB Backup
# Powered by aspbiz
#2004-09

# Setting
# Set the database name, database login name, password, backup path, log path, data file location, and backup mode
# By default, the backup method is tar, mysqldump, or mysqldotcopy.
# By default, log on to the mysql database with root (empty) and back up to/root/dbxxxxx. tgz
DBName = mysql
DBUser = root
DBPasswd =
BackupPath =/root/
LogFile =/root/db. log
DBPath =/var/lib/mysql/
# BackupMethod = mysqldump
# BackupMethod = mysqlhotcopy
# BackupMethod = tar
# Setting End

NewFile = "$ BackupPath" db $ (date + % y % m % d). tgz
DumpFile = "$ BackupPath" db $ (date + % y % m % d)
OldFile = "$ BackupPath" db $ (date + % y % m % d -- date = '5 days ago '). tgz

Echo "-----------------------------------------"> $ LogFile
Echo $ (date + "% y-% m-% d % H: % M: % S") >>$ LogFile
