Use this SQL script when changing domains on a WordPress site. Whether you’re moving from an old domain to a new domain or you’re changing from a development domain to a production domain this will work. __STEP1: always backup your database. __STEP2: change the ‘oldsite.com’ and ‘newsite.com’ variables to your own. __STEP3: make sure your databa…

With the help of your code I got a backup of my WordPress on another WordPress and with the help of ChatGPT made this text up to make scripts to copy all the database and media to a backup of WordPress. Here is what came up with:

A script to copy WordPress to a backup WordPress from rday1 to server. Replace them name in here with what your WordPress domin name.

curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
chmod +x wp-cli.phar
mv wp-cli.phar /usr/local/bin/wp
ssh-keygen -t rsa -b 4096
ssh-copy-id root@rday1
nano /root/.my.cnf

[client]
user=root
password=your_password

chmod 600 /root/.my.cnf

On rday1

nano Script on rday1: WP-copy-DB_to_server.sh

#!/bin/bash

wp db export --allow-root --path=/var/www/html backup.sql
scp "/root/backup.sql" root@server:/root/backup.sql

back on other WordPress

nano Get-WP-DB-from_rday1.sh

#!/bin/bash
wp db import /root/backup.sql --allow-root --path=/var/www/html
mysql wordpressdb < /root/wordpress-change-domain-migration.sql
rsync -avP --delete root@rday1:/var/www/html/wp-content/uploads/ /var/www/html/wp-content/uploads

chmod 700 Get-WP-DB-from_rday1.sh

nano wordpress-change-domain-migration.sql

SET @oldsite='https://rday.me/blog';
SET @newsite='http://server';
UPDATE wp_options SET option_value = replace(option_value, @oldsite, @newsite) WHERE option_name = 'home' OR option_name = 'siteurl';
UPDATE wp_posts SET post_content = replace(post_content, @oldsite, @newsite);
UPDATE wp_links SET link_url = replace(link_url, @oldsite, @newsite);
UPDATE wp_postmeta SET meta_value = replace(meta_value, @oldsite, @newsite);

/* only uncomment next line if you want all your current posts to post to RSS again as new */
#UPDATE wp_posts SET guid = replace(guid, @oldsite, @newsite)

on rday1 again.

crontab -e
0 2 * * * /root/WP-copy-DB_to_server.sh

Then back on server

crontab -e

20 2 * * * /root/Get-WP-DB-from_rday1.sh

On rday1 again

ssh-copy-id
ssh-copy-id root@server

That it's.

Cane test by running this on rday1

sh WP-copy-DB_to_hp2.sh

Then on server

sh Get-WP-DB-from_rday1.sh

I any one does this post back let me know if it works.
