LINUX Automatic backup script file

First I set up a folder under the/root/backup directory,

#mkdir/root/backup/mysqlbackup

After five o'clock every day, a file will be saved here.

Then create a new file

#vim/root/mysqlautobak

Input:

Filename= ' Date +%y%m%d '

mysqldump--all-databases-uroot-p (mysql password) >/root/backup/mysqlbackup/mysql$file.sql

　　

Save Exit!

So that it can execute

#chomd +x/root/mysqlautobak

And then we're done crontab.

#vi/etc/crontab

　　

Add a row

　　

5 * * * Root/root/mysqlautobak

Save exit.

Restart your Crond service process

#/etc/rc.d/init.d/crond Restart

Don't forget, the last step is to add a task to the crontab so you don't have to tap into trivial commands every time you backup.

Under Linux:

MySQL:: Shell script for automatic database backup under Linux
The program on the Linux server updates the MySQL database every day, so it reminds me to write a shell script, combined with crontab, to backup the database regularly. In fact, it's very simple, mainly using MySQL's mysqldump command.

The script reads as follows:
#!/bin/sh
# File:/home/mysql/backup.sh
# Database Info
Db_name= "Test"
Db_user= "username"
db_pass= "Password"

# Others VARs
Bin_dir= "/usr/local/mysql/bin"
Bck_dir= "/home/mysql/backup"
Date= ' Date +%f '

# TODO
$BIN _dir/mysqldump--opt-u$db_user-p$db_pass $DB _name | gzip > $BCK _dir/db_$date.gz

Then use the Add this script to the/etc/crontab Timer task:

5 * * 0 mysql/home/mysql/backup.sh

Well, every Sunday 5:01 the system automatically runs the backup.sh file to back up the MySQL database.
