#First rewrite any request to the wrong domain to use the correct one (here www.)

RewriteCond %{HTTP_HOST} !^www\.

RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

#Now, rewrite to HTTPS:

RewriteCond %{HTTPS} off

RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

The commands for modifying file permissions and ownership are:

• chmod – change permissions

• chown – change ownership.

A new folder was created on a data partition called /DATA/SHARE

# sudo chmod -R ugo+rw /DATA/SHARE

The breakdown of the above command looks like:

• sudo – this is used to gain admin rights for the command on any system that makes use of sudo (otherwise you'd have to 'su' to root and run the above command without 'sudo')

• chmod – the command to modify permissions

• -R – this modifies the permission of the parent folder and the child objects within

• ugo+rw – this gives User, Group, and Other read and write access.

chown -R "Username" /DATA/SHARE        (Replace Username with real username to whom you want to give ownership)

Let's break this down.

• sudo – admin rights must be used since we are dealing with a folder that belongs to another user

• chown – the command for changing ownership

• -R – the recursive switch to make sure all child objects get the same ownership changes

• Username – the new owner of the folder

• /DATA/SHARE – the directory to be modified

CHANGING PLESK VHOSTS DIRETORY FROM /var/www TO /home/var/www

CREATE DIRECTORIES

mkdir -p /home/var/www

rsync -avz /var/www /home/var/www
/usr/local/psa/bin/transvhosts.pl --dest-dir /home/var/www --correct-scripts

If you want to change Plesk mailbox directories please review this technical article for guidance.

CREATE DIRECTORIES
mkdir -p /home/var/mail
rsync -avz /var/mail /home/var/mail

Connect to the server using SSH/RDP.
Find what SMTP and IMAP/POP3 servers are in use:

# /usr/local/psa/admin/bin/mailmng --features | egrep 'SMTP_Server|IMAP_POP3_Server'
$features['SMTP_Server'] = "Postfix";
$features['IMAP_POP3_Server'] = "Dovecot"; $features['SMTP_Server_package'] = "postfix"; $features['IMAP_POP3_Server_package'] = "dovecot";

Stop the SMTP service:

# service postfix stop
Open the file /etc/psa/psa.conf and change the PLESK_MAILNAMES_D variable:
specify a new location for mailbox directory so that it is like:

# grep PLESK_MAILNAMES_D /etc/psa/psa.conf PLESK_MAILNAMES_D <new_mailnames_directory>

Note: To avoid performance degradation, the new location for the mailboxes directory should be located in the local file system - it should not be mounted as a network share, such as NFS.

Move mailboxes from the current directory to the new location with the
command:

# cp -ap /var/qmail/mailnames/* <new-mailnames-directory> If dovecot is in use, set the new location in the file /etc/dovecot/dovecot.conf by modifying values in the lines below:

# egrep 'mail_home|mail_location' /etc/dovecot/dovecot.conf mail_home = <new_mailnames_directory>/%Ld/%Ln mail_location = maildir:<new_mailnames_directory>/%Ld/%Ln/Maildir
Restart the dovecot service:

# service dovecot restart
After all the steps are done, start SMTP service and reconfigure mail settings using the mchk utility:

# service postfix start
# plesk repair mail
Before creating new mailboxes on new domains configure SELinux in the following way:
following is not required for selinux disabled server.
# chcon -R -t mail_spool_t <new_mailnames_directory>
