Need a specialist in MySQL/MariaDB optimization on VPS (Linux).

Budget: 3500 UAH Deadline: 2 days

Hello, Vladislav. If the server does not restart under load and is throwing errors, the problem is usually not in one parameter, but in a combination: MySQL/MariaDB configuration, VPS limits, disk, memory, and query logic. I will first find the bottleneck through logs and metrics, then stabilize the service and adjust the configuration to your actual loads. I have experience with Linux/VPS administration and database optimization for e-commerce and high-traffic projects. I am ready to take on the task and quickly bring order.

Such tasks are my specialization. I work with Linux VPS + MariaDB/MySQL under load, I understand why the server "drops" and how to fix it systematically, not just by restarting. I deploy and configure VPS from scratch — from choosing the configuration to a production-ready state, so I understand the infrastructure from the inside.

What I will do first:

Diagnosis — I will find the cause before touching anything:
— I will review the slow query log, error log, SHOW PROCESSLIST
— I will check innodb_buffer_pool_size, max_connections, tmp_table_size, and other key parameters in my.cnf
— I will look at the load: CPU, RAM, I/O during peak times
— I will check for blocked queries, deadlocks, tables without indexes

What usually causes such problems:
— innodb_buffer_pool_size is too small for the volume of data
— incorrect max_connections → the server is overwhelmed
— heavy queries without indexes hold locks
— tmp_table_size / sort_buffer_size are not suitable for the server
— OOM killer kills MySQL when there is not enough RAM

What you will receive as a result:
— configured my.cnf for your server and load
— problematic queries resolved or recommendations for indexes
— a server that does not crash and restarts normally
— comments on each parameter so you understand what and why

Please provide the server specifications (RAM, number of databases, approximate number of queries) — I will immediately tell you what exactly is wrong and how much time it will take. Expand

Good day! It is necessary to review the server logs and all its settings to determine the cause and promptly eliminate it.

Good day
My name is Dmytro, from King Kong Lab. We have experience working with VPS (Linux) and optimizing MySQL/MariaDB under load — we can figure out the cause of instability and bring the server to normal operation.
What we will do:
- conduct server diagnostics (load, CPU/RAM, I/O, logs)
- find the cause of crashes and errors
- optimize MySQL/MariaDB (configuration, queries, indexes)
- check and configure the server environment (PHP, caching, limits)
- eliminate "bottlenecks" that cause the server to crash
- ensure that the server operates stably without constant failures
We work carefully, even in cases where the server cannot simply be restarted — first analysis, then safe adjustments.
We are ready to connect, take a look at the server, and propose a specific solution. Expand

I can connect and properly understand your VPS: find the reason why MySQL/MariaDB crashes under load and bring the server to stable operation without constant errors.

What I will do: I will check the database configurations, logs, CPU/memory/disk load, find the bottleneck, optimize the settings, and ensure that everything works stably after the adjustments. If the problem is not only in the database but also in the server itself, I will see that and fix it as well.

I can start immediately. I need access to the VPS and preferably the latest error logs or a screenshot of what is currently happening.

I will help! Great experience! Write in private!!!!!!!!!!!!!!!!!!!!!

I can:
- perform diagnostics without stopping the server
- analyze logs and load (CPU, RAM, I/O)
- find the cause of crashes/errors
- optimize MySQL/MariaDB configuration
- identify and optimize "heavy" queries

If necessary, I will set up monitoring to prevent the problem from recurring.

I am ready to connect quickly and stabilize the server.

I can take a look and fix it.

I have solved load issues before.

But more often than not, the problem is not with MySQL but with how the website interacts with it.

Write to me, we will figure it out.
