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.
data.sqlfiles are located in the database subdirectory of Zabbix sources. If Zabbix was installed from distribution packages, refer to the distribution documentation.
schema.sqlshould be imported (no images.sql nor data.sql)
UTF-8 is the only encoding supported by Zabbix. It is known to work without any security flaws. Users should be aware that there are known security issues if using some of the other encodings.
shell> mysql -uroot -p<password> mysql> create database zabbix character set utf8 collate utf8_bin; mysql> grant all privileges on zabbix.* to [email protected] identified by '<password>'; mysql> quit;
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
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
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 -E Unicode -T template0 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
Support of Timescale DB has been added in Zabbix 4.2.0 and it is experimental.
timescaledb.sql script is located in database/postgresql (along with regular schema.sql, images.sql, data.sql). The script must be run after the regular PostgreSQL database has been created:
cat timescaledb.sql | sudo -u zabbix psql zabbix
The script assumes that TimescaleDB extension has been already installed in the database (installation instructions).
TimescaleDB extension should also be enabled for the specific DB by executing:
echo "CREATE EXTENSION IF NOT EXISTS timescaledb CASCADE;" | sudo -u postgres psql zabbix
Running this command requires DB admin privileges.
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 [email protected]_host "mkdir /tmp/zabbix_images" shell> scp -r misc/images/png_modern [email protected]_host:/tmp/zabbix_images/
Now prepare the database:
shell> cd /path/to/zabbix-sources/database/oracle shell> sqlplus zabbix/[email protected]_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 [email protected]_host "rm -rf /tmp/zabbix_images"
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
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
Using SQLite is supported for Zabbix proxy only!
shell> cd database/sqlite3 shell> sqlite3 /var/lib/sqlite/zabbix.db < schema.sql
