Linux server implements daily scheduled backup of MySQL database shell scripts

The Linux server uses the system crontab to regularly execute Backup files and save the backup results by date to achieve the backup purpose.

1. Create the path to save the backup file/mysqldata

# Mkdir/mysqldata

2. Create the/usr/sbin/bakmysql file.

# Vi/usr/sbin/bakmysql

Input

Rq = 'date + % Y % m % d'

Tar zcvf/mysqldata/mysql1_rq.tar.gz/var/lib/mysql

Or write it

Rq = 'date + % Y % m % d'

Mysqldump -- all-databases-u root-p password>/mysqldata/mysql $ rq. SQL

/Var/lib/mysql is the directory of your database files. Some users are/usr/local/mysql/data.

/Mysqldata/indicates the directory where the backup file is saved. This can be done according to your requirements.

3. Modify file attributes to make them executable.

# Od.html 'target = '_ blank'> chmod + x/usr/sbin/bakmysql

4. Modify/etc/crontab

# Vi/etc/crontab

Add

01 3 *** root/usr/sbin/bakmysql

Indicates that a backup is performed at three o'clock every day.

5. Restart crond.

#/Etc/rc. d/init. d/crond restart

Complete.

In this way, you can see such files in/mysqldata every day.
