Duplicated site isn't recognized as a site

Question

I've duplicated a site using the following code. All code worked fine until the last row (the site itself goes up on the web but the last row of code fails and I get an error):

echo "Please enter the domain of the site for duplication"
read domain
echo "Please enter the password of the site's DB user"
read -s psw

cp -r /var/www/html/${domain} /var/www/html/test
sed -i "s/${domain}/test"/g /var/www/html/test/wp-config.php
mysql -u root -p <<-MYSQL
    DROP user IF EXISTS 'test'@'localhost'; SELECT user FROM mysql.user;
    DROP database IF EXISTS test; show databases;

    CREATE user 'test'@'localhost' IDENTIFIED BY '${psw}';
    CREATE database test;
    GRANT ALL PRIVILEGES ON test.* TO test@localhost;
MYSQL

cd /var/www/html/test
wp search-replace "${domain}" "test" --allow-root

The last WPCLI command outputs:

Error: The site you have requested is not installed.

The same goes for other WPCLI commands. For some reason, WPCLI doesn't recognize my test site.

Any idea why WPCLI doesn't recognize my site when I'm clearly inside its directory?

Update for motivast:

mysql -u root -p <<-MYSQL
    DROP user IF EXISTS 'test'@'localhost'; SELECT user FROM mysql.user;
    DROP database IF EXISTS test; show databases;

    CREATE user 'test'@'localhost' IDENTIFIED BY '${psw}';
    CREATE database test;
    GRANT ALL PRIVILEGES ON test.* TO test@localhost;
MYSQL

mysqldump -u root -p ${domain} > test.sql
mysql -u root -p test < test.sql

Did I have the logic right? Did I passed the test?

Error is from the last command wp search-replace "${domain}" "test" --allow-root. Your WordPress site is not yet installed and you want to execute command which require WordPress to be installed.

Earlier in script you are dropping test database and creating new one, but you have to fill it with WordPress tables. Without this tables WordPress is not installed as the error says. You have to install WordPress by visiting your test page in the browser or execute wp core install with arguments in the command line.

You can also duplicate your database using mysqldump and mysql commands:

Dump: mysqldump -u root -p [database_name] > dumpfilename.sql

Import: mysql -u root -p [database_name] < dumpfilename.sql

Following script will make this for your:

#!/bin/bash

if [ $# -ne $EXPECTED_ARGS ]
then

echo -n "Enter root mysql password:"

$CP -r $DIR_OLD $DIR_NEW

echo "Dump database"
# Dump database
$MYSQLDUMP -u root -p$DBROOT_PASS $DBNAME_OLD > "${TMPDIR}/dbdump.sql"

# Create new database if not exists and add privileges.
Q1="DROP DATABASE IF EXISTS $DBNAME_NEW;"
Q2="DROP USER '$DBUSER_NEW'@'localhost';"
Q3="CREATE DATABASE $DBNAME_NEW COLLATE utf8_general_ci;"
Q4="CREATE USER '$DBUSER_NEW'@'localhost' IDENTIFIED BY '$DBPASS_NEW';"
Q5="GRANT ALL PRIVILEGES ON $DBNAME_NEW.* TO '$DBUSER_NEW'@'localhost' IDENTIFIED BY '$DBPASS_NEW';"
Q6="FLUSH PRIVILEGES;"

SQL="${Q1}${Q2}${Q3}${Q4}${Q5}${Q6}"

echo "Create database"
$MYSQL -e "${SQL}" -u root -p$DBROOT_PASS

echo "Import database"
# Import dumped database
$MYSQL -u root -p$DBROOT_PASS $DBNAME_NEW < "${TMPDIR}/dbdump.sql"

echo "Create wp config"
# Create new wordpress config
cd $DIR_NEW && $WP core config --dbname=${DBNAME_NEW} --dbuser=${DBUSER_NEW} --dbpass=${DBPASS_NEW} --dbhost="localhost" --allow-root --skip-check --force

echo "Replace domain"
# Replace domain in new wp site
cd $DIR_NEW && $WP search-replace "${DOMAIN_OLD}" "${DOMAIN_NEW}" --allow-root

You can use it in the following way:

sudo ./wpdup.sh /var/www/test /var/www/testnew wp_test wp_testnew wp_testnew xxxxxx test.dev testnew.dev
