1 Database creation scripts

Overview

A Zabbix database must be created during the installation of Zabbix server or proxy.

This section provides scripts for creating a Zabbix database. A separate schema script is provided for each supported database.

schema.sql, images.sql and data.sql files are located in the database subdirectory of Zabbix sources. If Zabbix was installed from distribution packages, refer to the distribution documentation.

For a Zabbix proxy database, only schema.sql should be imported (no images.sql nor data.sql)

Scripts

MySQL

shell> mysql -uroot -p<password>
       mysql> create database zabbix character set utf8 collate utf8_bin;
       mysql> grant all privileges on zabbix.* to zabbix@localhost identified by '<password>';
       mysql> quit;
       # stop here if you are creating database with Zabbix packages
       shell> cd database/mysql
       shell> mysql -uzabbix -p<password> zabbix < schema.sql
       # stop here if you are creating database for Zabbix proxy
       shell> mysql -uzabbix -p<password> zabbix < images.sql
       shell> mysql -uzabbix -p<password> zabbix < data.sql

PostgreSQL

Please refer to this section if you are installing Zabbix from packages.

You need to have database user with permissions to create database objects. The following shell command will create user zabbix. Specify password when prompted and repeat password (note, you may first be asked for sudo password):

shell> sudo -u postgres createuser --pwprompt zabbix

Now we will set up the database zabbix (last parameter) with the previously created user as the owner (-O zabbix) and import initial schema and data (assuming you are in the root directory of Zabbix sources):

shell> sudo -u postgres createdb -O zabbix zabbix
       shell> cd database/postgresql
       shell> cat schema.sql | sudo -u zabbix psql zabbix

Stop here if you are creating database for Zabbix proxy.

shell> cat images.sql | sudo -u zabbix psql zabbix
       shell> cat data.sql | sudo -u zabbix psql zabbix

The above commands are provided as an example that will work in most of GNU/Linux installations. You can use different commands, e. g. "psql -U <username>" depending on how your system/database are configured. If you have troubles setting up the database please consult your Database administrator.

Oracle

We assume that a zabbix database user with password password exists and has permissions to create database objects in ORCL service located on the host Oracle database server with a user shell user having write access to /tmp directory. Zabbix requires a Unicode database character set and a UTF8 national character set. Check current settings:

sqlplus> select parameter,value from v$nls_parameters where parameter='NLS_CHARACTERSET' or parameter='NLS_NCHAR_CHARACTERSET';

If you are creating a database for Zabbix server you need to have images on a predefined location on Oracle host. Copy all images from misc/images/png_modern to /tmp/zabbix_images directory on Oracle host:

shell> cd /path/to/zabbix-sources
       shell> ssh user@host "mkdir /tmp/zabbix_images"
       shell> scp -r misc/images/png_modern user@host:/tmp/zabbix_images/

Now prepare the database:

shell> cd database/oracle
       shell> sqlplus zabbix/password@host/ORCL
       sqlplus> @schema.sql
       # stop here if you are creating database for Zabbix proxy
       sqlplus> @images.sql
       sqlplus> @data.sql

After executing the images.sql script the /tmp/zabbix_images temporary directory can be removed.

IBM DB2

shell> db2 "create database zabbix using codeset utf-8 territory us pagesize 32768"
       shell> cd database/ibm_db2
       shell> db2batch -d zabbix -f schema.sql
       # stop here if you are creating database for Zabbix proxy
       shell> db2batch -d zabbix -f images.sql
       shell> db2batch -d zabbix -f data.sql

It is important to set UTF-8 locale for Zabbix server, Zabbix proxy and the web server running Zabbix frontend. Otherwise text information from Zabbix will be interpreted by IBM DB2 server as non-UTF-8 and will be additionally converted on the way from Zabbix to the database and back. The database will store corrupted non-ASCII characters.

Zabbix frontend uses OFFSET and LIMIT clauses in SQL queries. For this to work, IBM DB2 server must have DB2_COMPATIBILITY_VECTOR variable be set to 3. Run the following command before starting the database server:

shell> db2set DB2_COMPATIBILITY_VECTOR=3

SQLite

shell> cd database/sqlite3
       shell> sqlite3 /var/lib/sqlite/zabbix.db < schema.sql
       # stop here if you are creating database for Zabbix proxy
       shell> sqlite3 /var/lib/sqlite/zabbix.db < images.sql
       shell> sqlite3 /var/lib/sqlite/zabbix.db < data.sql

If using SQLite with Zabbix proxy, database will be automatically created if it does not exist.
