Turbocharge WordPress: Step-by-Step innodb_buffer_pool_size Optimization on Ubuntu


Introduction

Is your WordPress site running at less than optimal speed? Let's ramp up its performance by tweaking a critical MySQL/MariaDB setting on your Ubuntu server. In this guide, we'll walk you through the exact steps to update `innodb_buffer_pool_size` for a faster and more responsive WordPress website.


Steps:


1. Access Your Ubuntu Server

  • **Login to Your Server:**
Use your preferred method (SSH, terminal, etc.) to log in to your Ubuntu server.

2. Locate MySQL/MariaDB Configuration File

  • **Navigate to the Configuration File:**
Use a text editor to open the MySQL/MariaDB configuration file, which is commonly found at `/etc/mysql/my.cnf` or `/etc/my.cnf`, `/etc/mysql/mariadb.conf.d/50-server.cnf`.


3. Calculate the New innodb_buffer_pool_size

  • **Check Available RAM:**
Run a command like `free -m` to determine the available RAM on your server.

  • **Calculate the New Size:**
Decide on a percentage of available RAM to allocate (e.g., 70-80%) and calculate the new `innodb_buffer_pool_size` using this formula: `innodb_buffer_pool_size = available_RAM * percentage / 100`.

4. Modify innodb_buffer_pool_size

  • **Edit the Configuration File:**
Locate the `innodb_buffer_pool_size` parameter in the configuration file.

  • **Update the Value:**
Replace the existing value with the calculated size.


5. Restart MySQL/MariaDB

  • **Restart the Service:**

Execute the following command to restart the MySQL/MariaDB service:
sudo service mysql restart


6. Verify Changes

  • **Check MySQL/MariaDB Status:**
Ensure that the changes have been applied by checking the status of the MySQL/MariaDB service:
sudo service mysql status


7. Test Website Performance

  • **Evaluate Performance:**
Before and after the adjustment, use tools like GTmetrix or Google PageSpeed Insights to assess your website's performance.


Conclusion

Congratulations! You've successfully optimized your WordPress site by adjusting the `innodb_buffer_pool_size` on your Ubuntu server. Enjoy the improved speed and responsiveness of your website.
