Why PHPTracker? Because it’s not “just a tracker”, it contains a seeder server too so the distribution of your files is automatic. This is a big step for the content providers to adapt this amazing technology and change the stereotype that “torrent = warez”.

MySQL backup databases into separate files by weekdays with compression

May 15th, 2010 Comments off

I’ve found in Net script, which only backups databases into separate files and modified it. I’ve added gzip compression and backup by weekday. So, you can cron this job daily and get backups for each weekday. It’s very flexible backup algorithm.

Script is below:

#!/bin/bash

# This script backups every MySQL database to its own file

#Some variables you can set how you like
USER='<possible root>'
PASSWORD='<password>'
DAYOFWEEK=`/bin/date +"%w"`
OUTPUTDIR="/usr/backup/mysql/$DAYOFWEEK" # backup dir
MYSQLDUMP='/usr/local/bin/mysqldump'     # path to mysqldump, may be /usr/bin/mysqldump
MYSQL='/usr/local/bin/mysql'             # path to mysql, may be /usr/bin/mysql  

#Clean up any old backups
rm -f $OUTPUTDIR/*

#Get a list of databases names except the system one
databases=`$MYSQL --user=$USER --password=$PASSWORD -e 'SHOW DATABASES;' | grep -Ev '(Database|information_schema)'`

#Dump each database in turn and compress the output with gzip
for db in $databases; do
$MYSQLDUMP --opt --hex-blob --force --user=$USER --password=$PASSWORD $db | gzip > $OUTPUTDIR/$db.gz
done

Relevant search in MySQL

September 11th, 2009 2 comments

We have an query. Query is a long phrase, for example 4 words. We want to found in table most relevant results.

There is built-in operator in MySQL which called MATCH – AGAINST. This operator executes relevant search in specified FULLTEXT indexes.

Our table:

CREATE TABLE `clients` (
`id` int(10) unsigned NOT NULL auto_increment,
`firm` varchar(150) NOT NULL default '',
`name_` varchar(30) NOT NULL default '',
`address` varchar(150) default NULL,
PRIMARY KEY  (`id`),
FULLTEXT KEY `firm` (`firm`,`name_`,`address`)
) ;

To find all rows which fields `firm`,`name_`,`address` contain ‘lawyer Braun park avenue’ use the query (for MySQL 5.0)

SELECT * FROM `clients` WHERE MATCH ( `firm`,`name_`,`address` ) AGAINST ( 'lawyer Braun park avenue' )

Important. All fields you are searching through must be in one FULLTEXT index. You can create FULLTEXT index for each search type.

Important. If you want to search by a part of word you can be dissapointed. While MySQL indexes the words from the start, the Fulltext-search also available only with ending wildcard * (wildcards enabled only in boolean mode). When you using a boolean mode, you need to sort the results manually with ORDER clause.

SELECT *, MATCH ( `firm`,`name_`,`address` ) AGAINST ( 'lawy* Braun park avenu* IN BOOLEAN MODE' ) AS `score` FROM `clients` WHERE MATCH ( `firm`,`name_`,`address` ) AGAINST ( 'lawy* Braun park avenu* IN BOOLEAN MODE' ) ORDER BY `score` DESC
