ownCloud migration in linux

Now a day’s most of the IT companies implemented ownCloud because they are getting more benefits from it and many things were automated. So, today i’m going to explain how to migrate owncloud from one server to another.

New Server

First install the ownCloud to new server then move/copy required files/folders from old server.

1) Download & Install the ownCloud package

Use the below link to download the latest version of ownCloud package then install it.

# Download the ownCloud package #
root@2daygeek [~]# wget https://download.owncloud.org/community/owncloud-7.0.4.tar.bz2

# Extract the ownCloud archive file #
root@2daygeek [~]# tar -xjvf owncloud-7.0.4.tar.bz2

# Change folder permission #
root@2daygeek [~]# chown -R groupname:username owncloud

# Create Database #
mysql> create database cloud;
Query OK, 1 row affected (0.00 sec)

# Create Database user #
mysql> CREATE USER 'cloud'@'localhost' IDENTIFIED BY 'cloud';
Query OK, 0 rows affected (0.00 sec)

# Assign the PRIVILEGES #
mysql> GRANT ALL PRIVILEGES ON cloud.* TO 'cloud'@'localhost';
Query OK, 0 rows affected (0.00 sec)

# FLUSH PRIVILEGES #
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

2) Configuration

Navigate your browser to http://Your-domain.com/owncloud, it will ask you to create the username & password to mange your owncloud.

3) Remove data & config folders

Remove data & config from new server.

# Remove data folder #
root@2daygeek [~]# rm -Rf data

# Remove config folder #
root@2daygeek [~]# rm -Rf config

Old Server

take backup of database,data & config folders then move/copy to new server.

1) Backup database,data & config folders

Follow the below steps to take backup of required data from old server.

# Database Backup #
root@2daygeek [~]# mysqldump -u root -p owncloud > owncloud.sql

# Sync Database Backup to new server #
root@2daygeek [~]# rsync -avz -e "ssh -p 22" /root/owncloud.sql 192.168.1.137:/root

# Sync data folder #
root@2daygeek [~]# rsync -avz -e "ssh -p 22" /home/cloudana/public_html/owncloud/data/* 192.168.1.137:/home/cloudtest/public_html/owncloud/data/

# Sync config folder #
root@2daygeek [~]# rsync -avz -e "ssh -p 22" /home/cloudana/public_html/owncloud/config/* 192.168.1.137:/home/cloudtest/public_html/owncloud/config/

New Server

Modify the configuration according to the new server details to make it work on owncloud properly.

# Restore Database Backup #
root@2daygeek [~]# mysql -u root -p owncloud < owncloud.sql

# Change data folder permission #
root@2daygeek [~]# chown -R groupname:username data

# Change config folder permission #
root@2daygeek [~]# chown -R groupname:username config

Modify config.php file

root@2daygeek [~]# nano config.php
0 => 'New-domain-name',
datadirectory' => '../current-data-directory-location',
'dbname' => 'New-DB-name',
'dbuser' => 'New-DB-User-name',
'dbpassword' => 'New-DB-password',

Goahead and access the owncloud from new server without any issues.
