[scp command]

Hi,
You can use Linux commands to transfer 200GB data from one server to another.
For that you can use either rsync command or scp command.

- scp command: scp -P port -r root@destinationserverIP:/home/path /home/destinationpath
- rsync command : rsync A host:B

These both the commands used to transfer data but rsync command is better because it uses delta transfer algorithm which makes transfer more faster.

[domain]

Hi everyone,
I know this is old post and you have also post right thing about redirection to https.
I just want to add that you can also redirect from http to https from cpanel:
- Login to cpanel
- Under domain section click on "Force HTTPS Redirect"
- From this you can redirect your website from http to https without adding code in .htaccess file.

According to me this is the easiest way for the https redirection.

Hi,
If you are on shared server then you can ask your hosting company regarding SSL certificate.
You can ask them to install Free SSL for your website or if they don't provide FreeSSL then you can install paid SSL certificate.

If you have VPS hosting plan then you can yourself install SSL certificate on your server.
You can follow these steps to install SSL on your server:

Login to the WHM by going to yourdomain.com/whm in a browser. Replace yourdomain.com with your domain.
Once you get to the login page enter your username and password.
Username will be root.
Password will be the root password for your server.

The WHM login page.
If this is your first time logging into the WHM you may see a page titled "Feature Showcase". Click on Exit to WHM at the bottom of the page.The Feature Showcase page with 'Exit to WHM' spotlighted.

Access The Install SSL Tool
Once you are logged into the WHM you need to use the SSL installer to upload and activate a certificate on the domain. The easiest way to find it is through the WHM search tool.

In the WHM Search box on the left side enter "Install an SSL Certificate"
Click on the "Install an SSL Certificate on a Domain" link that appears.
You should now be at the Install an SSL Certificate on a Domain page in the WHM.

The Install an SSL Certificate on a Domain page.

Install The SSL
When you purchased the SSL certificate you should have received files for your certificate, key and Certificate Authority bundle. If you do not have these files you will need to get them from the company you purchased the certificate from.

On the "Install an SSL Certificate on a Domain" page enter your domain your certificate was issued for into the "Domain:" The Domain box.
Paste the Certificate, Key and Certificate Authority Bundle into their respective boxes.The certificate, key and CA bundle boxes.
Click the Install button at the bottom.

The SSL certificate should be installed and you can begin using it.

Hi,
I am commenting on this old post because i want to add solution of this problem.
Seems like the update went wrong and some files got corrupted.

You can try this to fix it:

• Download a new Wordpress installation zip https://wordpress.org/download/
  
• Remove the folders wp-admin & wp-includes from your server
  
• Reupload those folders from the fresh downloaded Wordpress zip

Note: this does not delete your site content, the content of your website is in the database and in the wp-content folder.

Hi,
I know this is old post but i just want tel about SSH port change. I just want to say that according to security purpose you have to change your SSH port number.
Its because default SSH port is 22 and everyone know this, so for security purpose you have to change it.

You have to change port in sshd_config file and for uncommented port settings line. you can find your "sshd_config" file in /etc/ssh/ path.
After changing it you have to restart sshd service to reflect the changes

For detailed steps you can check this link: https://hoststud.com/resources/how-to-change-ssh-port-on-centos-linux-server.151/
