Changing domain and base URL for PrestaShop 1.7

How to change your main domain in case you change your host? Or how to setup your dev environment on localhost when you import a live Production environment?

You have to change different URLs and settings in the database. Here’s how.

Let’s say you have a current working shop at https://my-domain-1.com/prefix1 and you want to change to https//my-domain-2/prefix2

# 0. edit your Database parameters in /app/config/parameters.php
# then, use these lines to update your configuration for your new host/domain
# 1. Shop URL
update *_shop_url set domain="my-domain-2", domain_ssl="my-domain-2" where main=1 and domain="my-domain-1";
# 2. Prefix
update *_shop_url set physical_uri="/prefix2/" where main=1 and domain="my-domain-2";
# 3. Enable (or disable) HTTPS
update *_configuration set PS_SSL_ENABLED=1; # 1=enable HTTPS, 0=disable HTTPS
# 4. Edit your /.htaccess by replacing "^my-domain-1$" by "^my-domain-2$"

So to set up a local environment under http://localhost, it gives us the following configuration:

# 0. edit your Database parameters in /app/config/parameters.php
# 1. then
update *_shop_url set domain="localhost", domain_ssl="localhost" where main=1 and domain="my-domain-1";
update *_shop_url set physical_uri="/" where main=1 and domain="localhost";
update *_configuration set PS_SSL_ENABLED=0;
# 2. Edit your /.htaccess by replacing "^my-domain-1$" by "^localhost$"
