Backup WordPress project files / db using bash script

August 8, 2013  |  5 Comments  |  by Raj (MagePsycho)  |  Linux, Magento

WordPress is undoubtedly the most popular blogging platform on the Internet. And when it comes to the maintenance or regular backups, life is not easier unless you have some backup script which works great via SSH & cron daemons.

Here is the custom backup script used for taking backup of wordpress project files & db:
(If you want backup script for Magento then please go here)

#!/bin/bash
#@author		MagePsycho <magepsycho@gmail.com>
#@website		http://www.magepsycho.com
#@blog			http://www.blog.magepsycho.com
#@version		0.1.0

#/************************ EDIT VARIABLES ************************/
projectName=magepsycho_blog
backupDir=/home/magepsycho/_backups
#/************************ //EDIT VARIABLES **********************/

fileName=$projectName-$(date +"%Y-%m-%d")
host=$(grep DB_HOST "wp-config.php" |cut -d "'" -f 4)
username=$(grep DB_USER "wp-config.php" | cut -d "'" -f 4)
password=$(grep DB_PASSWORD "wp-config.php" | cut -d "'" -f 4)
dbName=$(grep DB_NAME "wp-config.php" |cut -d "'" -f 4)

printf "What kind of backup you would like?\n[ d ] DB backup only\n[ f ] Files backup only\n[ b ] Files backup with DB\n"
read backupType
if [[ $backupType = @(d|b) ]]; then
	echo "----------------------------------------------------"
	echo "Dumping MySQL..."
	mysqldump -h "$host" -u "$username" -p"$password" "$dbName" | gzip > $fileName.sql.gz
	echo "Done!"
fi

if [[ $backupType = @(f|b) ]]; then
	echo "----------------------------------------------------"
	echo "Archiving Files..."
	tar -zcf $fileName.tar.gz * .htaccess
	echo "Done!"
	echo "----------------------------------------------------"
	echo "Cleaning..."
	rm -f $fileName.sql.gz
	echo "Done!"
fi

if [[ $backupType = @(d|f|b) ]]; then
	echo "----------------------------------------------------"
	mkdir -p $backupDir;
	echo "Moving file to backup dir..."
	if [[ $backupType == d ]]; then
		mv $fileName.sql.gz $backupDir
	fi

	if [[ $backupType = @(f|b) ]]; then
		mv $fileName.tar.gz $backupDir
	fi
	echo "Done!"
else
	echo "Invalid selection!"
fi

Or you can download it from here: [WordPress Backup Script]
Notes: If you get the following error:

syntax error in conditional expression: unexpected token `(‘
line 20: syntax error near `@(d’
line 20: `if [[ $backupType = @(d|b) ]]; then’

then this means you are using older version of bash (< 4.0). And you need to patch the script by adding the following line after bash script declaration: [code language="bash"]shopt -s extglob[/code]

What does this script do?

1. Gives options for backup type which are:
– DB backup only
– Files backup only
– Files backup with DB
2. Dumps the database by taking db info from wp-config.php
3. Makes a copy of project files and compresses it in .tar.gz format.
4. Deletes the dumped SQL file as it’s already copied in compressed file.
5. Creates backup dir if not exists
6. Copies the compressed project file to the backup dir.

Besides, you can also setup cron job to run this backup script at regular intervals.

How to run backup script?

1. Edit _wpbackup.sh to configure variables ‘projectName’ & ‘backupDir’
2. Upload the edited _wpbackup.sh to the root of your WordPress installation
3. Run following series of commands in terminal:

cd /path/to/wordpress/root
chmod +x _wpbackup.sh
ex -sc $'%s/\r$//e|x' _wpbackup.sh
sh _wpbackup.sh

4. You will get the compressed backup file at backup dir

Backup Magento project files / db using bash script

July 1, 2013  |  8 Comments  |  by Raj (MagePsycho)  |  Linux, Magento

I have googled for the bash script to backup Magento sites/db but none of them worked for me the way I wanted.
So I decided to create a custom bash script which is simple and does the job perfectly.

I have developed the script for my own need. But I thought it would be helpful if shared with you guys as well.
Here goes the overall backup script:

#!/bin/bash
#@author		MagePsycho <magepsycho@gmail.com>
#@website		http://www.magepsycho.com
#@version		0.1.0

#/************************ EDIT VARIABLES ************************/
projectName=magepsycho
backupDir=/home/magepsycho/_backups
#/************************ //EDIT VARIABLES **********************/

dbXmlPath="app/etc/local.xml"
{
host="$(echo "cat /config/global/resources/default_setup/connection/host/text()" | xmllint --nocdata --shell $dbXmlPath | sed '1d;$d')"
username="$(echo "cat /config/global/resources/default_setup/connection/username/text()" | xmllint --nocdata --shell $dbXmlPath | sed '1d;$d')"
password="$(echo "cat /config/global/resources/default_setup/connection/password/text()" | xmllint --nocdata --shell $dbXmlPath | sed '1d;$d')"
dbName="$(echo "cat /config/global/resources/default_setup/connection/dbname/text()" | xmllint --nocdata --shell $dbXmlPath | sed '1d;$d')"
}

fileName=$projectName-$(date +"%Y-%m-%d")
printf "What kind of backup you would like?\n[ d ] DB backup only\n[ f ] Files backup only\n[ b ] Files backup with DB\n"
read backupType
if [[ $backupType = @(d|b) ]]; then
	echo "----------------------------------------------------"
	echo "Dumping MySQL..."
	mysqldump -h $host -u $username -p$password $dbName > $fileName.sql
	echo "Done!"
fi

if [[ $backupType = @(f|b) ]]; then
	echo "----------------------------------------------------"
	echo "Archiving Files..."
	printf "Skip /media folder?\ny: Yes\nn: No\n"
	read skipMedia
	if [ $skipMedia == y ]; then
		tar -zcf $fileName.tar.gz --exclude=var --exclude=includes --exclude=media * .htaccess
	else
		tar -zcf $fileName.tar.gz --exclude=var --exclude=includes * .htaccess
	fi
	echo "Done!"
	echo "----------------------------------------------------"
	echo "Cleaning..."
	rm -f $fileName.sql
	echo "Done!"
fi

if [[ $backupType = @(d|f|b) ]]; then
	echo "----------------------------------------------------"
	mkdir -p $backupDir;
	echo "Moving file to backup dir..."
	if [ $backupType == d ]; then
		mv $fileName.sql $backupDir
	fi

	if [[ $backupType = @(f|b) ]]; then
		mv $fileName.tar.gz $backupDir
	fi
	echo "Done!"
else
	echo "Invalid selection!"
fi

Notes: If you get the following error:

line 24: syntax error near `@(d’
line 24: `if [[ $backupType = @(d|b) ]]; then’

then this means you are using older version of bash (< 4.0). And you need to patch the script by adding the following line after bash script declaration:[code language="bash"] shopt -s extglob [/code]

What does this script do?

1. Gives options for backup type which are:
– DB backup only
– Files backup only
– Files backup with DB
2. Dumps the database by taking DB info from XML configuration.
3. Makes a copy of project files and compresses it in .tar.gz format.
While copying it also gives options whether to exclude media folder or not.
Note that by default ‘var’ & ‘includes’ folder are excluded by the script.
4. Deletes the dumped SQL file as it’s already copied in the compressed file.
5. Creates backup dir if not exists
6. Copies the compressed project file to the backup dir.

Besides, you can also setup Cron job to run this backup script at regular intervals.

sh _magebackup.sh

4. You will get the compressed backup file at backup dir

Upgrading Magento from 1.6.0.0 to 1.6.1.0 via diff file

November 10, 2011  |  4 Comments  |  by Raj (MagePsycho)  |  Latest, Linux, Magento

Uprading in Magento has never been an easy task for me. But this time I successfully upgraded the Magento(from 1.6.0.0 to 1.6.1.0) with minimum no of tries. And I’m going to share the success story 🙂

First, I tried with the following series of SSH commands but unluckily didn’t work for me:

rm -rf var/cache var/session
rm -rf downloader/pearlib/cache/* downloader/pearlib/download/*
rm -f downloader/pearlib/pear.ini
chmod 550 ./mage
./mage mage-setup .
./mage config-set preferred_state stable
./mage list-installed
./mage list-upgrades
./mage install http://connect20.magentocommerce.com/community Mage_All_Latest --force
php shell/indexer.php reindexall

I went through all the above steps successfully but when i tried to logout and re-login at the backend, version number didn’t change in the admin footer. It means there was no effect of above code at least for me.

After that I tried the following SSH commands:

rm -rf var/cache/* var/session/*
rm -rf downloader/pearlib/cache/* downloader/pearlib/download/*
rm -f downloader/pearlib/pear.ini
wget http://www.magentocommerce.com/downloads/assets/1.6.1.0/1.6.0.0-1.6.1.0.diff.gz
zcat 1.6.0.0-1.6.1.0.diff.gz > 1.6.0.0-1.6.1.0.diff
patch -p0 -f < 1.6.0.0-1.6.1.0.diff

Notes:
– Deleting pear.ini is important in case If you have copied the same magento from another location. Else updates will be installed in your source location instead of current location.
– You need to run the above commands from the root of your Magento installation.

After successfully applying the above commands, I refreshed the magento page but got the following error:

“Error in file: “…/app/code/core/Mage/Sales/sql/sales_setup/upgrade-1.6.0.3-1.6.0.4.php” – SQLSTATE[42S01]: Base table or view already exists: 1050 Table ‘sales_order_aggregated_updated’ already exists”

and this error was easily removed just by renaming the following file:

app/code/core/Mage/Sales/sql/sales_setup/upgrade-1.6.0.3-1.6.0.4.php

Besides i didn’t get any error and hence upgrading Magento task was successfull.
This is the first time i upgraded via applying the .diff file and was so happy that it worked for me 🙂

Cheers!!

Happy Upgrading!
