By using MySQL you can benefit from features in the MySQL infrastructure such as backup, restore and high availability.
For Artifactory to run with MySQL you must create a dedicated MySQL database instance and then configure Artifactory to use it as described in the following sections.
Before You Continue
Before proceeding with the steps below, please make sure you have read and followed the steps described in Changing the Default Storage.
Creating the Artifactory MySQL Database
Supported MySQL Versions
Artifactory supports MySQL v5.5 and above with
InnoDB engine which is the default provided.
Artifactory provides a script that will execute the SQL commands you need to create your MySQL database.
The script can be found in
$ARTIFACTORY_HOME/misc/mysql/createdb.sql and is displayed below.
You should review the script and modify it as needed to correspond to your specific environment.
We recommend providing Artifactory with full privileges on the database
Selecting a Case-sensitive Collation
While MySQL Database Server is not case-sensitive by default, it is important to select a case-sensitive collation because Artifactory is case-sensitive.
For example, in the
createdb.sql script above COLLATE is set to "
Increasing MySQL Default Packet Size
Since some data files (builds, configurations etc.) are stored in MySQL, it is extremely important to increase the maximum allowed packet size used by MySQL to avoid errors related to large packets.
(Please refer to MySQL documentation: Packet Too Large).
It is recommended to change this in the
/etc/my.cnf file as follows:
/etc/my.cnf Absolute Path
/etc/my.cnf does not already exist it should be created under the absolute path and not under
After modifying the maximum allowed packed size you need to restart MySQL
Tuning MySQL for Artifactory
When using Artifactory with MySQL it is recommended to use the InnoDB engine with the following tuning parameters configured in the
After tuning, you need to restart MySQL
Configuring Artifactory to use MySQL
(If you do not have this file you can take it from the standalone zip distribution or directly from the JFrog domain). For a full explanation on the contents of this file please refer to The Bundled Storage Configurations.
- Adjust the connection definitions in the
$ARTIFACTORY_HOME/etc/storage.propertiesfile to match the attributes of the Artifactory database you created.
You must configure the database URL and username/password to use. The schema and tables are created first time Artifactory is run using the new database.
Download the MySQL JDBC driver (available from the MySQL website) and copy the
mysql-connector-java-<version>.jarfile into the server's shared lib directory.
$TOMCAT_HOME/libwhen installed as a service or
$ARTIFACTORY_HOME/tomcat/libin the standalone version.
Make sure your driver has the same permissions as the rest of the files in the shared lib directory.
- Start Artifactory.
Storing BLOBs inside MySQL
The suggested (and recommended) configuration stores all artifact information in MySQL while the artifact binary data is stored on the file system (under
While it is not recommended, it is possible to store BLOBs inside MySQL provided that the typical BLOB size is relatively small. Storing large BLOBs in MySQL can cause memory issuesbecause MySQL buffers BLOBs rather than streaming them (please refer to MySQL Bug #15089) and may result in
OutOfMemory errors with large binaries depending on your JVM heap size.
To store BLOBs in MySQL, in the
storage.propreties file set
binary.provider.type=fullDb and change
max_allowed_packet to be higher than the maximum artifact size you intend to store in Artifactory.
