Rules to Migrate WordPress from Shared Hosting to a Cloud Server with Zero Downtime

Moving to a Cloud Server 

Various bloggers start with shared hosting. This may be valuable for starting, yet when development creates (e.g. over two or three hundred visitors for consistently), you should consider moving the site to an individual cloud server. Moving to one isn't amazingly jumbled, just take after the steps viably and you can migrate a WordPress blog/webpage inside two or three hours, with no downtime.

Step 1. Make a Backup 

You need to support all your records, close by the MySQL database (from your current shared hosting server). Most of the shared hosting suppliers have a clear GUI for managing servers, for instance, cPanel.

Fortification Files (pictures, subjects, modules) 

You don't need to fortification focus WordPress archives, yet you ought to support pictures (you may have starting now exchanged for a post), subjects, and modules. With a particular final objective to do this, to begin with, make a record of the wp-substance registry (right-click => pack as pack), then download it.

Move down the Database 

In cPanel, go to "Support Wizard => MySQL Databases".

You'll have the ability to download the MySQL database in *.sql.gz plan. Save it as backup_db.sql.gz on your desktop.

Step 2. Set Up the Cloud Server with LAMP Stack 

Dispatch a dot (cloud server) with Ubuntu 12.04 and tail this associate for the basic setup process:Ubuntu Server Setup. Since the cloud server is set up, you need to present the WordPress conditions, for instance, MySQL, PHP and a web server like Apache. Tail this manual for set up a LAMP stack.

Step 3. Present WordPress

Once the LAMP stack is set up, present the latest version of WordPress. To do thusly, fundamentally tail this guide:Installing WordPress on Ubuntu.

Step 4. Make a Virtual Host 

Make an Apache virtual host for dealing with your WordPress blog. Make another record in the site-availabledirectory:

sudo nano/et cetera/apache2/locales accessible/yourdomain.com

Incorporate a virtual host (supplant yourdomain.com and username as requirements be) for the online diary. Each VirtualHostblock portrays a seperate cloud server and the number 80 demonstrates the port that Apache will listen on.ServerName addresses your range name and DocumentRoot should show the establishment of the WordPress inventory.

<VirtualHost *:80>

ServerName yourdomain.com

DocumentRoot/var/www/

</VirtualHost><VirtualHost *:80>

ServerName http://www.yourdomain.com

Divert lasting/http://yourdomain.com/

</VirtualHost>

By then enable this virtual host using the Apache utility a2ensite. It takes the above course of action and encourages Apache to listen for yourdomain.com.

sudo a2ensite yourdomain.com

In no time reload the Apache server. At whatever point you reveal any changes in server game plan, you ought to reload the server to apply those movements.

sudo administration apache2 reload

Step 5. Restore Database and Files

The WordPress foundation is without further ado set up yet you haven't imported your old articles, pictures, subjects, et cetera. We should exchange the records first.

Exchange the Backup Files – MySQL Database and File Contents to VPS 

scp is astoundingly advantageous for exchanging archives. Like FTP, you can trade archives, yet SCP does it securely over SSH. For exchanging records, you need to pass two conflicts to the summon. The first is the territory of the record you have to exchange and the second one is the goal server (as username@server_ip_address). To exchange the fortification archives, fundamentally execute these charges locally (on your PC) and it will exchange the records to home registry of the server.

scp ~/Downloads/backup_db.sql.gz username@server_ip_address:

scp ~/Downloads/wp-content.zip username@server_ip_address:

Restore the Database 

To restore the database, login to the server and sort (supplant database_name, database_useraccordingly) the request underneath:

mysql – h localhost – u database_user – p database_name < backup_db.sql.gz

The request requires two or three disputes: the – h decision for deciding the host address (for this circumstance it's localhost, in light of the way that the database is running on the same server), the second conflict, – u, gives the database username, the third decision, – p, suggests the mystery word will be supplied on brief, the fourth decision shows the name of the WordPress database, and the last conflict is the information – the fortification database.

You will be drawn nearer to enter the watchword for the database customer. Inside a couple of minutes, the database substance will be outside to the predefined database.

Restore wp-content Files 

To restore subjects, exchanged media (pictures, recordings, et cetera.), and modules, simply think (using the unzipcommand) the zip archive. It will isolated and union the substance into the current wp-substance registry.

sudo unfasten wp-content.zip - d/var/www/

Step 6. Test your Blog 

To achieve zero downtime, this movement is indispensable. You have to guarantee that the online diary is set up properly on the new zone. To do this, first redesign your hosts record.

sudo nano/and so forth/has

Add this line to the hosts report (now when you visit yourdomain.com, it will demonstrate your new server, yet just on your PC – this makes testing less requesting).

server_ip_address yourdomain.com

Next, clear your DNS store (since you've updated the hosts report, you ought to clear the DNS store to apply the movements. nscd is wonderful little instrument for flushing out the DNS store results)

sudo administration nscd restart

In no time, if you visit yourdomain.com, it will stack pages from your new server. In case it looks obviously (all your articles, pictures, pages, modules, hand artworks et cetera.), then it infers you are ready and you should continue forward to the accompanying step. Something else, endeavor to understand what turned out severely. (Consequent to testing adequately, remove the above line from the hosts record).

Step 7. Update Your DNS Settings 

In the blink of an eye you should upgrade the DNS settings with your Domain Registrar. For the A record, update the IP area to the new regard (IP area of your VPS) or you could in like manner move your DNS to your VPS supplier (and incorporate A records there). For Sakshamapp, you need to put these name servers:

ns1.sakshamapp.com

ns2.sakshamapp.com

ns3.sakshamapp.com

Note: Your DNS server will start spreading the new values yet it will require some venture, so don't end your old shared hosting in a flash after the move (in a perfect world after a day).
