| [[createdb]] |
| == Database Setup |
| |
| During the init phase of Gerrit you will need to specify which database to use. |
| |
| [[createdb_h2]] |
| === H2 |
| |
| If you choose H2, Gerrit will automatically set up the embedded H2 database as |
| backend so no set up or configuration is necessary. |
| |
| Using the embedded H2 database is the easiest way to get a Gerrit |
| site up and running, making it ideal for proof of concepts or small team |
| servers. On the flip side, H2 is not the recommended option for large |
| corporate installations when using ReviewDb. This is because there is no easy way to interact |
| with the database while Gerrit is offline, it's not easy to backup the data, |
| and it's not possible to set up H2 in a load balanced/hotswap configuration. |
| |
| If this option interests you, you might want to consider |
| link:linux-quickstart.html[the quick guide]. |
| |
| [[createdb_derby]] |
| === Apache Derby |
| |
| If Derby is selected, Gerrit will automatically set up the embedded Derby |
| database as backend so no set up or configuration is necessary. |
| |
| Currently only support for embedded mode is added. There are two other |
| deployment options for Apache Derby that can be added later: |
| |

| Derby Network Server (standalone mode)] |
| |

| Embedded Server (hybrid mode)] |
| |
| [[createdb_postgres]] |
| === PostgreSQL |
| |
| This option is more complicated than the H2 option but is recommended |
| for larger installations. It's the database backend with the largest userbase |
| in the Gerrit community. |
| |
| Create a user for the web application within PostgreSQL, assign it a |
| password, create a database to store the metadata, and grant the user |
| full rights on the newly created database: |
| |
| ---- |
| $ createuser --username=postgres -RDIElPS gerrit |
| $ createdb --username=postgres -E UTF-8 -O gerrit reviewdb |
| ---- |
| |
| Visit PostgreSQL's link:http://www.postgresql.org/docs/9.1/interactive/index.html[documentation] for further information regarding |
| using PostgreSQL. |
| |
| [[createdb_mysql]] |
| === MySQL |
| |
| Requirements: MySQL version 5.1 or later. |
| |
| This option is also more complicated than the H2 option. Just as with |
| PostgreSQL it's also recommended for larger installations. |
| |
| Create a user for the web application within the database, assign it a |
| password, create a database, and give the newly created user full |
| rights on it: |
| |
| ---- |
| mysql |
| |
| CREATE USER 'gerrit'@'localhost' IDENTIFIED BY 'secret'; |
| CREATE DATABASE reviewdb DEFAULT CHARACTER SET 'utf8'; |
| GRANT ALL ON reviewdb.* TO 'gerrit'@'localhost'; |
| FLUSH PRIVILEGES; |
| ---- |
| |
| Visit MySQL's link:http://dev.mysql.com/doc/[documentation] for further |
| information regarding using MySQL. |
| |
| [[createdb_mariadb]] |
| === MariaDB |
| |
| Requirements: MariaDB version 5.5 or later. |
| |
| Refer to MySQL section above how to create MariaDB database. |
| |
| Visit MariaDB's link:https://mariadb.com/kb/en/mariadb/[documentation] for further |
| information regarding using MariaDB. |
| |
| [[createdb_oracle]] |
| === Oracle |
| |
| PostgreSQL or H2 is the recommended database for Gerrit Code Review. |
| Oracle is supported for environments where running on an existing Oracle |
| installation simplifies administrative overheads, such as database backups. |
| |
| Create a user for the web application within sqlplus, assign it a |
| password, and grant the user full rights on the newly created database: |
| |
| ---- |
| SQL> create user gerrit identified by secret_password default tablespace users; |
| SQL> grant connect, resources to gerrit; |
| ---- |
| |
| JDBC driver ojdbc6.jar must be obtained from your Oracle distribution. Gerrit |
| initialization process tries to copy it from a known location: |
| |
| ---- |
| /u01/app/oracle/product/11.2.0/xe/jdbc/lib/ojdbc6.jar |
| ---- |
| |
| If this file can not be located at this place, then the alternative location |
| can be provided. |
| |
| Instance name is the Oracle SID. Sample database section in |
| $site_path/etc/gerrit.config: |
| |
| ---- |
| [database] |
| type = oracle |
| instance = xe |
| hostname = localhost |
| username = gerrit |
| port = 1521 |
| ---- |
| |
| Sample database section in $site_path/etc/secure.config: |
| |
| ---- |
| [database] |
| password = secret_password |
| ---- |
| |
| [[createdb_maxdb]] |
| === SAP MaxDB |
| |
| SAP MaxDB is a supported database for running Gerrit Code Review. However it is |
| recommended only for environments where you intend to run Gerrit on an existing |
| MaxDB installation to reduce administrative overhead. |
| |
| In the MaxDB studio or using the SQLCLI command line interface create a user |
| 'gerrit' with the user class 'RESOURCE' and a password <secret password>. This |
| will also create an associated schema on the database. |
| |
| To run Gerrit on MaxDB, you need to obtain the MaxDB JDBC driver. It can be |
| found in your MaxDB installation at the following location: |
| |
| - on Windows 64bit at "C:\Program Files\sdb\MaxDB\runtime\jar\sapdbc.jar" |
| - on Linux at "/opt/sdb/MaxDB/runtime/jar/sapdbc.jar" |
| |
| It needs to be stored in the 'lib' folder of the review site. |
| |
| In the following sample database section it is assumed that the database name is |
| 'reviewdb' and the database is installed on localhost: |
| |
| In $site_path/etc/gerrit.config: |
| |
| ---- |
| [database] |
| type = maxdb |
| database = reviewdb |
| hostname = localhost |
| username = gerrit |
| |
| ---- |
| |
| In $site_path/etc/secure.config: |
| |
| ---- |
| [database] |
| password = <secret password> |
| ---- |
| |
| Visit SAP MaxDB's link:http://maxdb.sap.com/documentation/[documentation] for further |
| information regarding using SAP MaxDB. |
| |
| [[createdb_db2]] |
| === DB2 |
| |
| IBM DB2 is a supported database for running Gerrit Code Review. However it is |
| recommended only for environments where you intend to run Gerrit on an existing |
| DB2 installation to reduce administrative overhead. |
| |
| Create a system wide user for the Gerrit application, and grant the user |
| full rights on the newly created database: |
| |
| ---- |
| db2 => create database gerrit |
| db2 => connect to gerrit |
| db2 => grant connect,accessctrl,dataaccess,dbadm,secadm on database to gerrit; |
| ---- |
| |
| JDBC driver db2jcc4.jar and db2jcc_license_cu.jar must be obtained |
| from your DB2 distribution. Gerrit initialization process tries to copy |
| it from a known location: |
| |
| ---- |
| /opt/ibm/db2/V10.5/java/db2jcc4.jar |
| /opt/ibm/db2/V10.5/java/db2jcc_license_cu.jar |
| ---- |
| |
| If these files cannot be located at this place, then an alternative location |
| can be provided during init step execution. |
| |
| Sample database section in $site_path/etc/gerrit.config: |
| |
| ---- |
| [database] |
| type = db2 |
| database = gerrit |
| hostname = localhost |
| username = gerrit |
| port = 50001 |
| ---- |
| |
| Sample database section in $site_path/etc/secure.config: |
| |
| ---- |
| [database] |
| password = secret_password |
| ---- |
| |
| [[createdb_hana]] |
| === SAP HANA |
| |
| SAP HANA is a supported database for running Gerrit Code Review. However it is |
| recommended only for environments where you intend to run Gerrit on an existing |
| HANA installation to reduce administrative overhead. |
| |
| In the HANA studio or the SAP HANA Web-based Development Workbench create a user |
| 'GERRIT2' with the role 'RESTRICTED_USER_JDBC_ACCESS' and a password |
| <secret password>. This will also create an associated schema on the database. |
| As this user would be required to change the password upon first login you might |
| want to to disable the password lifetime check by executing |
| 'ALTER USER GERRIT2 DISABLE PASSWORD LIFETIME'. |
| |
| To run Gerrit on HANA, you need to obtain the HANA JDBC driver. It can be found |
| as described |
| link:http://help.sap.com/saphelp_hanaplatform/helpdata/en/ff/15928cf5594d78b841fbbe649f04b4/frameset.htm[here]. |
| It needs to be stored in the 'lib' folder of the review site. |
| |
| In the following sample database section it is assumed that HANA is running on |
| the host 'hana.host' and listening on port '4242' where a schema/user GERRIT2 |
| was created: |
| |
| In $site_path/etc/gerrit.config: |
| |
| ---- |
| [database] |
| type = hana |
| hostname = hana.host |
| port = 4242 |
| username = GERRIT2 |
| |
| ---- |
| |
| In order to configure a specific database in a multi-database environment (MDC) |
| the database name has to be specified additionally: |
| |
| In $site_path/etc/gerrit.config: |
| |
| ---- |
| [database] |
| type = hana |
| hostname = hana.host |
| database = tdb1 |
| port = 4242 |
| username = GERRIT2 |
| |
| ---- |
| |
| In $site_path/etc/secure.config: |
| |
| ---- |
| [database] |
| password = <secret password> |
| ---- |
