🔎 How to Show the Last Queries Executed on MySQL

Have you ever wondered if there's a convenient way to check the last queries executed on ALL MySQL servers? 🤔 Well, you're in luck! In this blog post, we'll explore a simple solution to this common question and empower you to easily track and monitor your database activity. 💪

The Problem 😕

While MySQL provides the ability to view the last executed query on a single server, finding a solution to view the last executed queries on multiple servers simultaneously can be a daunting task. It becomes especially challenging when you have multiple databases spread across different servers or even different hosting providers. 😫

The Solution 💡

Fear not! We've got you covered with a nifty solution using the general_log feature in MySQL. Here's a step-by-step guide on how to achieve this:

1. Enable the General Query Log 📝

   Open your MySQL configuration file (my.cnf or my.ini) and locate the general_log setting. If it's commented out, uncomment it and set the value to 1. This will enable the general query log feature. Don't forget to restart the MySQL server for the changes to take effect.

2. Specify the Log File Location 📂

   Specify the location where you want the log file to be created. You can use an absolute path like /var/log/mysql/mysql.log or a relative path like mysql.log (within the MySQL data directory). Choose a location that suits your needs, but make sure it has write permissions for the MySQL server.

3. Start MySQL Server with General Logging 🚀

   Start the MySQL server with the general logging feature enabled. This can be done by specifying the --general-log option when starting the server or by using the appropriate command for your operating system. For example:

   mysqld --general-log

4. Execute Queries and Monitor the Log 🕵️‍♀️

   Perform your queries on the MySQL servers you want to monitor. The queries will be written to the specified log file in the order they were executed. To view the last executed queries, simply tail the log file or use your favorite text editor to open it.

   tail -n 10 /var/log/mysql/mysql.log

   In the above command, we're tailing the last 10 lines of the log file to see the latest queries. Feel free to adjust the number to match your preferences.

5. Disable General Logging (optional) ❌

   Once you have gathered the required information, you can disable general logging on your MySQL servers to prevent the log file from growing too large or consuming unnecessary resources. Simply revert the changes made to the MySQL configuration file and restart the server.
