Mariadb and Mysql configurations are the same
What is configured here is that mariadb
modifies the configuration file.
vi /etc/my.cnf.d/server.cnf
[mysqld]
slow_query_log=on
slow_query_log_file=/data/mysql_data/slow_query_log.log
long_query_time=2
- slow_query_log=on turns on slow sql query
- slow_query_log_file=/data/mysql_data/slow_query_log.log slow sql storage path
- long_query_time=2 sql is OK. If it exceeds 2 seconds, it will be recorded in the slow sql log and can be adjusted.
Create slow sql log file
mkdir -p /data/mysql_data
touch /data/mysql_data/slow_query_log.log
chown mysql:mysql /data/mysql_data/slow_query_log.log
Restart mariadb
systemctl restart mariadb
View log
cat /data/mysql_data/slow_query_log.log
