I have written some guides & tips related to Hosting & Ubuntu server.
1). Redirect website
This is a guide for redirect by htaccess.
Redirect form old URLs to new URLs with specific URLs
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_HOST} ^oldwebsite.com [NC,OR]
RewriteCond %{HTTP_HOST} ^www.oldwebsite.com [NC]
RewriteRule ^(.*)$ http://newwebsite.com/$1 [L,R=301,NC]
</IfModule>
Redirect form all old URLs to new URL(Homepage)
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_HOST} ^oldsite.com [NC,OR]
RewriteCond %{HTTP_HOST} ^www.oldsite.com [NC]
RewriteRule ^(.*)$ https://newsite.com/ [L,R=301,NC]
</IfModule>
2). Change PHP.ini
PHP5 Path
