Overview

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

This section provides instructions for creating a Zabbix database. A separate set of instructions is available for each supported database.

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;

If you use Zabbix packages continue with instructions for Debian/Ubuntu or RHEL/CentOS to import the data into the database.

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

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

If you use Zabbix packages continue with instructions for Debian/Ubuntu or RHEL/CentOS to import the data into the database.

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

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 from Zabbix sources on the host where Oracle is running. Copy them to a directory /tmp/zabbix_images on the Oracle host:

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

Now prepare the database:

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

Now the temporary directory can be removed:

shell> ssh user@oracle_host "rm -rf /tmp/zabbix_images"

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 

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

Using SQLite is supported for Zabbix proxy only!

shell> cd database/sqlite3
shell> sqlite3 /var/lib/sqlite/zabbix.db < schema.sql
