Performs structural modeling schema audits, analyzing table designs, constraints, indexes, data types, and naming conventions by dumping schema layouts without querying full datasets.
# 1. Setup Vendor Repositories
mkdir -p vendor
git clone https://github.com/jmrenouard/multi-db-docker-env vendor/multi-db-docker-env
git clone https://github.com/jmrenouard/test_db vendor/test_db
# 2. Start Container
cd vendor/multi-db-docker-env
[ ! -f .env ] && echo "DB_ROOT_PASSWORD=mysqltuner_test" > .env
make percona80
# 3. Inject Sample Data
cd $PROJECT_ROOT
find "vendor/test_db" -name "employees.sql" -exec sh -c 'cd $(dirname {}) && mysql -h 127.0.0.1 -u root -pmysqltuner_test < $(basename {})' \;
# 4. Execute Scenario: Schemadir
perl mysqltuner.pl --host 127.0.0.1 --user root --pass mysqltuner_test --verbose --schemadir=schemas --cvefile vulnerabilities.csv --reportfile=mysqltuner_report.html

ℹ Health Score KPI execution time: 0.000s
-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
Consider stopping or dedicate server for additional process other than mysqld.
setup swappiness lower or equal to 10
setup Max running number events greater than 1M
Use 'id' or '_<table>_id' for Primary Key naming in 11 table(s)
Use BIGINT UNSIGNED AUTO_INCREMENT for Primary Keys in 11 table(s)
Use singular names for table in 4 table(s)
Remove unused indexes.
Restrict Host for 'root'@'%' to 'root'@LimitedIPRangeOrLocalhost
RENAME USER 'root'@'%' TO 'root'@LimitedIPRangeOrLocalhost;
Enable require_secure_transport to force all connections to use SSL.
Enforce SSL for remote users (ALTER USER ... REQUIRE SSL)
22 CVE(s) found for your MySQL release. Consider upgrading your version !
MySQL was started within the last 24 hours: recommendations may be inaccurate
Enable the slow query log to troubleshoot bad queries
Reduce or eliminate unclosed connections and network issues
We will suggest raising the 'join_buffer_size' until JOINs not using indexes are found.
See https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_join_buffer_size
Increase binlog_cache_size (current value: 32768)
Unused indexes found: 2 index(es) should be reviewed and potentially removed.
Migration Risk (default_authentication_plugin): Removed in MySQL 9.0. Use caching_sha2_password or mysql-native-password (if enabled) instead.
Migration Risk (binlog_transaction_dependency_tracking): Removed in MySQL 8.4.
Migration Risk (avoid_temporal_upgrade): Removed in MySQL 8.4. Upgrading from very old versions (5.5) might need manual temporal upgrade.
Migration Risk (expire_logs_days): Removed in MySQL 8.4. Use binlog_expire_logs_seconds instead.
Set gtid_mode = ON to enable global transaction identifier replication.
Set enforce_gtid_consistency = ON to prevent unsafe replication operations.
Set binlog_transaction_dependency_tracking = WRITESET to improve parallel replication throughput.
Enable binlog_transaction_compression = ON to reduce replication stream size.
Increase binlog_cache_size to reduce disk spills for binary log transactions.
Enable source_verify_checksum = ON (or master_verify_checksum).
Variables to adjust:
DON'T APPLY SETTINGS BECAUSE THERE ARE TOO MANY PROCESSES RUNNING ON THIS SERVER. OOM KILL CAN OCCUR!

-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
Consider stopping or dedicate server for additional process other than mysqld.
setup swappiness lower or equal to 10
setup Max running number events greater than 1M
Use 'id' or '_<table>_id' for Primary Key naming in 11 table(s)
Use BIGINT UNSIGNED AUTO_INCREMENT for Primary Keys in 11 table(s)
Use singular names for table in 4 table(s)
Remove unused indexes.
Restrict Host for 'root'@'%' to 'root'@LimitedIPRangeOrLocalhost
RENAME USER 'root'@'%' TO 'root'@LimitedIPRangeOrLocalhost;
Enable require_secure_transport to force all connections to use SSL.
Enforce SSL for remote users (ALTER USER ... REQUIRE SSL)
22 CVE(s) found for your MySQL release. Consider upgrading your version !
MySQL was started within the last 24 hours: recommendations may be inaccurate
Enable the slow query log to troubleshoot bad queries
Reduce or eliminate unclosed connections and network issues
We will suggest raising the 'join_buffer_size' until JOINs not using indexes are found.
See https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_join_buffer_size
Increase binlog_cache_size (current value: 32768)
Unused indexes found: 2 index(es) should be reviewed and potentially removed.
Migration Risk (default_authentication_plugin): Removed in MySQL 9.0. Use caching_sha2_password or mysql-native-password (if enabled) instead.
Migration Risk (binlog_transaction_dependency_tracking): Removed in MySQL 8.4.
Migration Risk (avoid_temporal_upgrade): Removed in MySQL 8.4. Upgrading from very old versions (5.5) might need manual temporal upgrade.
Migration Risk (expire_logs_days): Removed in MySQL 8.4. Use binlog_expire_logs_seconds instead.
Set gtid_mode = ON to enable global transaction identifier replication.
Set enforce_gtid_consistency = ON to prevent unsafe replication operations.
Set binlog_transaction_dependency_tracking = WRITESET to improve parallel replication throughput.
Enable binlog_transaction_compression = ON to reduce replication stream size.
Increase binlog_cache_size to reduce disk spills for binary log transactions.
Enable source_verify_checksum = ON (or master_verify_checksum).
