Shell/Bash Script Migrating WordPress – Find and Replace all Instance of Domain Name in WordPress or MySQL Database

Migrating your WordPress site to a new domain or switching from HTTP to HTTPS can be daunting, especially when updating every instance of your old domain within your database. To simplify this process, we’ve created a powerful shell script that automates the entire procedure, ensuring a smooth and efficient transition.

What This Script Does:

  1. Backup Your Database: Before making any changes, the script creates a comprehensive backup of your MySQL database. This ensures that you have a fallback option in case anything goes wrong.
  2. Compress the Backup: The script then compresses the SQL dump file into a .tar.gz Archive for easy storage and retrieval.
  3. Find and Replace Domain Instances: Utilizing the sed Command: the script searches for all instances of your old domain and replaces them with the new domain across the entire SQL dump file.
  4. Re-import the Database: Finally, the script re-imports the modified SQL file into your MySQL database, seamlessly updating all domain references.

How to Use This Script:

  1. Download and Prepare: Save the script to your server and make it executable using chmod +x wpchangedomain.sh.
  2. Configure Variables: Update the script with your MySQL username, password, database name, old domain, and new domain.
  3. Execute the Script: Run the script by executing sh wpchangedomain.sh in your terminal.
  4. Verify Changes: After the script completes, check your WordPress site to ensure all instances of the old domain have been replaced successfully.

Benefits of Using This Script:

  • Automation: Automates the tedious task of finding and replacing domain instances in your database.
  • Safety: Creates a backup before making any changes, allowing for easy restoration if needed.
  • Efficiency: Saves time and reduces the risk of errors associated with manual updates.

Migrating your WordPress domain doesn’t have to be a complex and time-consuming task. With this shell script, you can ensure a smooth and efficient transition, allowing you to focus on what matters most – creating great content for your audience.
