**MySQLTuner** is a script written in Perl that allows you to review a MySQL installation quickly and make adjustments to increase performance and stability. The current configuration variables and status data is retrieved and presented in a brief format along with some basic performance suggestions.
|
||||
|
||||
**MySQLTuner** supports ~300 indicators for MySQL/MariaDB/Percona Server in this last version.
|
||||
|
||||
**MySQLTuner** is maintained and indicator collect is increasing week after week supporting a lot of configuration such as [Galera Cluster](http://galeracluster.com/), [TokuDB](https://www.percona.com/software/mysql-database/percona-tokudb), [Performance schema](https://github.com/mysql/mysql-sys), Linux OS metrics, [InnoDB](http://dev.mysql.com/doc/refman/5.7/en/innodb-storage-engine.html), [MyISAM](http://dev.mysql.com/doc/refman/5.7/en/myisam-storage-engine.html), [Aria](https://mariadb.com/kb/en/mariadb/aria/), ...
|
||||

***WARNING***
|
||||
--
|
||||
It is **extremely important** for you to fully understand each change
|
||||
you make to a MySQL database server. If you don't understand portions
|
||||
of the script's output, or if you don't understand the recommendations,
|
||||
**you should consult** a knowledgeable DBA or system administrator
|
||||
that you trust. **Always** test your changes on staging environments, and
|
||||
always keep in mind that improvements in one area can **negatively affect**
|
||||
MySQL in other areas.
|
||||
|
||||
It's **also important** to wait at least a day of uptime to get accurate results. In fact, running
|
||||
**mysqltuner** on a fresh restarted server is completely useless.
|
||||
|
||||
**Seriously - please review the FAQ section below.**
|
||||
|
||||
|
||||
Security recommendations
|
||||
--
|
||||
|
||||
Hi directadmin user!
|
||||
We detected that you run mysqltuner with da_admin's credentials taken from `/usr/local/directadmin/conf/my.cnf`, which might bring to a password discovery!
|
||||
Read link for more details [Issue #289](https://github.com/major/MySQLTuner-perl/issues/289).
|
||||
|
||||
What MySQLTuner is checking exactly ?
|
||||
--
|
||||
All checks done by **MySQLTuner** are documented in [MySQLTuner Internals](https://github.com/major/MySQLTuner-perl/blob/master/INTERNALS.md) documentation.
|
||||
|
||||
Download/Installation
|
||||
--
|
||||
|
||||
Choose one of these methods:
|
||||
|
||||
1) Script direct download (the simplest and shortest method):
|
||||
|
||||
```
|
||||
wget http://mysqltuner.pl/ -O mysqltuner.pl
|
||||
wget https://raw.githubusercontent.com/major/MySQLTuner-perl/master/basic_passwords.txt -O basic_passwords.txt
|
||||
wget https://raw.githubusercontent.com/major/MySQLTuner-perl/master/vulnerabilities.csv -O vulnerabilities.csv
|
||||
```
|
||||
|
||||
2) You can download the entire repository by using `git clone` or `git clone --depth 1 -b master` followed by the cloning URL above.
|
||||
|
||||
Optional Sysschema installation for MySQL 5.6
|
||||
--
|
||||
|
||||
Sysschema is installed by default under MySQL 5.7 and MySQL 8 from Oracle.
|
||||
By default, on MySQL 5.6/5.7/8, performance schema is enabled by default.
|
||||
For previous 5.6 version, you can follow this command to create a new database sys containing very useful view on Performance schema:
|
||||
|
||||
curl "https://codeload.github.com/mysql/mysql-sys/zip/master" > sysschema.zip
|
||||
# check zip file
|
||||
unzip -l sysschema.zip
|
||||
unzip sysschema.zip
|
||||
cd mysql-sys-master
|
||||
mysql -uroot -p < sys_56.sql
|
||||
|
||||
Optional Performance schema and Sysschema installation for MariaDB 10.x
|
||||
--
|
||||
|
||||
Sysschema is not installed by default under MariaDB 10.x.
|
||||
By default, on MariaDB, performance schema is disabled by default. consider activating performance schema across your my.cnf configuration file:
|
||||
|
||||
[mysqld]
|
||||
performance_schema = on
|
||||
|
||||
You can follow this command to create a new database sys containing very useful view on Performance schema:
|
||||
|
||||
curl "https://codeload.github.com/FromDual/mariadb-sys/zip/master" > mariadb-sys.zip
|
||||
# check zip file
|
||||
unzip -l mariadb-sys.zip
|
||||
unzip mariadb-sys.zip
|
||||
cd mariadb-sys-master/
|
||||
mysql -u root -p < ./sys_10.sql
|
||||
|
||||
Errors & solutions for performance schema installation
|
||||
|
||||
ERROR at line 21: Failed to open file './tables/sys_config_data_10.sql -- ported', error: 2
|
||||
Have a look at #452 solution given by @ericx
|
||||
|
||||
Performance tips
|
||||
--
|
||||
Metadata statistic updates can impact strongly performance of database servers and MySQLTuner.
|
||||
Be sure that innodb_stats_on_metadata is disabled.
|
||||
|
||||
set global innodb_stats_on_metadata = 0;
|
||||
|
||||

FAQ
|
||||
--
|
||||
|
||||
**Question: Will MySQLTuner fix my slow MySQL server?**
|
||||
|
||||
**No.** MySQLTuner is a read only script. It won't write to any configuration files, change the status of any daemons, or call your mother to wish her a happy birthday. It will give you an overview of your server's performance and make some basic recommendations for improvements that you can make after it completes. *Make sure you read the warning above prior to following any recommendations.*
|
||||
|
||||
**Question: Can I fire my DBA now?**
|
||||
|
||||
**MySQLTuner will not replace your DBA in any form or fashion.** If your DBA constantly takes your parking spot and steals your lunch from the fridge, then you may want to consider it - but that's your call.
|
||||
|
||||
**Question: Why does MySQLTuner keep asking me the login credentials for MySQL over and over?**
|
||||
|
||||
The script will try its best to log in via any means possible. It will check for ~/.my.cnf files, Plesk password files, and empty password root logins. If none of those are available, then you'll be prompted for a password. If you'd like the script to run in an automated fashion without user intervention, then create a .my.cnf file in your home directory which contains:
|
||||
|
||||
[client]
|
||||
user=someusername
|
||||
password=thatuserspassword
|
||||
|
||||
Once you create it, make sure it's owned by your user and the mode on the file is 0600. This should prevent the prying eyes from getting your database login credentials under normal conditions. If a [T-1000 shows up in a LAPD uniform](https://en.wikipedia.org/wiki/T-1000) and demands your database credentials, you won't have much of an option.
|
||||
|
||||
**Question: Is there another way to secure credentials on latest MySQL and MariaDB distributions ?**
|
||||
|
||||
You could use mysql_config_editor utilities.
|
||||
~~~bash
|
||||
$ mysql_config_editor set --login-path=client --user=someusername --password --host=localhost
|
||||
Enter password: ********
|
||||
~~~
|
||||
After which, `~/.mylogin.cnf` will be created with the appropriate access.
|
||||
|
||||
To get information about stored credentials, use the following command:
|
||||
|
||||
$mysql_config_editor print
|
||||
[client]
|
||||
user = someusername
|
||||
password = *****
|
||||
host = localhost
|
||||
|
||||
**Question: What's minimum privileges needed by a specific mysqltuner user in database ?**
|
||||
|
||||
mysql>GRANT SELECT, PROCESS,EXECUTE, REPLICATION CLIENT,SHOW DATABASES,SHOW VIEW ON *.* TO 'mysqltuner'@'localhost' identified by pwd1234;
|
||||
|
||||
**Question: What's minimum privileges needed by a specific mysqltuner user in database for MySQL 8 or MariaDB 10.5 ?**
|
||||
|
||||
mysql>GRANT SELECT, PROCESS,EXECUTE, REPLICA MONITOR,SHOW DATABASES,SHOW VIEW ON *.* TO 'mysqltuner'@'localhost' identified by pwd1234;
|
||||
|
||||
|
||||
**Question: It's not working on my OS! What gives?!**
|
||||
|
||||
These kinds of things are bound to happen. Here are the details I need from you in order to research the problem thoroughly:
|
||||
|
||||
* OS and OS version
|
||||
* Architecture (x86, x86_64, IA64, Commodore 64)
|
||||
* Exact MySQL version
|
||||
* Where you obtained your MySQL version (OS package, source, etc)
|
||||
* The full text of the error
|
||||
* A copy of SHOW VARIABLES and SHOW GLOBAL STATUS output (if possible)
|
||||
|
||||
**Question: How to perform CVE vulnerability checks?**
|
||||
|
||||
* Download vulnerabilities.csv from this repository.
|
||||
* use option --cvefile to perform CVE checks
|
||||
|
||||
**Question: How to use mysqltuner from a remote host?**
|
||||
Thanks to [@rolandomysqldba](http://dba.stackexchange.com/users/877/rolandomysqldba)
|
||||
|
||||
* You will still have to connect like a mysql client:
|
||||
|
||||
Connection and Authentication
|
||||
|
||||
--host <hostname> Connect to a remote host to perform tests (default: localhost)
|
||||
--socket <socket> Use a different socket for a local connection
|
||||
--port <port> Port to use for connection (default: 3306)
|
||||
--user <username> Username to use for authentication
|
||||
--pass <password> Password to use for authentication
|
||||
--defaults-file <path> defaults file for credentials
|
||||
|
||||
Since you are using a remote host, use parameters to supply values from the OS
|
||||
|
||||
--forcemem <size> Amount of RAM installed in megabytes
|
||||
--forceswap <size> Amount of swap memory configured in megabytes
|
||||
|
||||
* You may have to contact your remote SysAdmin to ask how much RAM and swap you have
|
||||
|
||||
If the database has too many tables, or very large table, use this:
|
||||
|
||||
--skipsize Don't enumerate tables and their types/sizes (default: on)
|
||||
(Recommended for servers with many tables)
|
||||
|
||||
**Question: Can I install this project using homebrew on Apple Macintosh?**
|
||||
|
||||
Yes! `brew install mysqltuner` can be used to install this application using [homebrew](https://brew.sh/) on Apple Macintosh.
|
||||
|
||||
