In the ever-evolving landscape of database management and analysis, ensuring the optimum performance and security of your MySQL databases is paramount. One effective method to achieve this is by analyzing logs such as error logs and slow query logs. This article will guide you through integrating a self-managed Filebeat with Alibaba Cloud Elasticsearch to collect MySQL logs, providing a comprehensive solution for querying, analyzing, and presenting these logs visually in Kibana.

Prerequisites

Before diving into the installation and configuration, ensure you have set up an Alibaba Cloud Elasticsearch cluster and an Elastic Compute Service (ECS) instance. Alibaba Cloud’s Elasticsearch service simplifies operations and management, offering a robust environment for log analysis.

Step 1: Install and Configure MySQL

First, connect to your ECS instance and install MySQL:

1wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
2sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
3sudo yum install mysql-server

Configure the MySQL error and slow query log files in the my.cnf file:

1sudo vim /etc/my.cnf
2
3[mysqld]
4log_queries_not_using_indexes = 1
5slow_query_log=on
6slow_query_log_file=/var/log/mysql/slow-mysql-query.log
7long_query_time=0
8
9[mysqld_safe]
10log-error=/var/log/mysql/mysqld.log

Optionally, create the log files manually if they don't exist:

1sudo mkdir /var/log/mysql
2sudo touch /var/log/mysql/mysqld.log
3sudo touch /var/log/mysql/slow-mysql-query.log
4sudo chmod 777 /var/log/mysql/slow-mysql-query.log /var/log/mysql/mysqld.log

Start MySQL and verify its status:

1sudo systemctl start mysqld
2sudo systemctl status mysqld

Step 2: Install and Configure Filebeat

Install Filebeat on your ECS instance following the setup instructions in the Kibana console. Enable the MySQL module:

1sudo filebeat modules enable mysql

Configure the module in mysql.yml to specify the paths of the log files:

1- module: mysql
2  # Error logs
3  error:
4    enabled: true
5    var.paths: ["/var/log/mysql/mysqld.log"]
6  # Slow logs
7  slowlog:
8    enabled: true
9    var.paths: ["/var/log/mysql/slow-mysql-query.log"]

Edit filebeat.yml to set up connections with your Kibana console and Elasticsearch cluster:

1filebeat.config.modules:
2  path: /etc/filebeat/modules.d/*.yml
3  reload.enabled: true
4  reload.period: 10s
5
6setup.kibana:
7  host: "https://<your_kibana_endpoint>:5601"
8
9output.elasticsearch:
10  hosts: ["https://<your_elasticsearch_endpoint>:9200"]
11  username: "elastic"
12  password: "<your_password>"

Start Filebeat to begin log collection:

1sudo filebeat setup
2sudo service filebeat start

Step 3: Analyze MySQL Logs with Kibana

Restart MySQL to begin generating logs for analysis. Access the Kibana console to view and analyze logs using the [Filebeat MySQL] Overview dashboard.

By following these steps, you can efficiently monitor and analyze your MySQL logs, leveraging the powerful Elasticsearch and Kibana tools on Alibaba Cloud.
