solved error - zabbix cinfigured with PostgreSQL

decided & installing zabbix tool for monitoring rdbms / no-sql database.

I got few error while installing zabbix with  PostgreSQL database. here i'm listing few with solution.

I created database manually in psq.

CREATE DATABASE zabbix;

ERROR 1)

....
....

pg_free_result() expects parameter 1 to be resource, boolean given [include/db.inc.php:566]

....
 

SOLUTION
I checked database "zabbix" which i was created by manually, no relation were found.
run the following command to create relation schema 

postgres@boss:[~]$ psql -hlocalhost zabbix
psql (9.0.6, server 9.0.0)
Type "help" for help.

zabbix=# \i /usr/share/zabbix-server-pgsql/schema.sql
zabbix=# \i /usr/share/zabbix-server-pgsql/images.sql
zabbix=# \i /usr/share/zabbix-server-pgsql/data.sql

ERROR 2)

....
....

zabbix server is not running the information displayed may not be current

....
 

SOLUTION

step 1) go through the log 

root@boss[~]#vi /var/log/zabbix/zabbix_server.log psql

19447:20130704:162637.902 Database is down. Reconnecting in 10 seconds.
 19447:20130704:162647.903 [Z3001] connection to database 'zabbix' failed: [0] FATAL:  role "zabbix" does not exist 

step 2) log clearly tells that no role in name of zabbix  exist in database

postgres@boss:[~]$ psql -hlocalhost zabbix
psql (9.0.6, server 9.0.0)
Type "help" for help.

zabbix=#CREATE ROLE zabbix WITH LOGIN; 

ERROR 3)

....
....
 19447:20130704:163227.949 Database is down. Reconnecting in 10 seconds.
 19447:20130704:163237.950 [Z3001] connection to database 'zabbix' failed: [0] FATAL:  role "zabbix" is not permitted to log in

may get above error if you don't have log-in rights,
SOLUTION

zabbix=#ALTER ROLE zabbix LOGIN; 

ERROR 4)

You are not able to choose some of the languages, because locales for them are not installed on the web server.

SOLUTION
  its waring message only, to  diaplsy installed locales

root@boss:[~]$locale -a 

to select & install missing locales by

root@boss:[~]$dpkg-reconfigure locales

SOLUTION
to check the owner of the relation under database zabbix, it must be zabbix. in my case it is public then I alter into zabbix

step 1) check the owner of the table in PostgreSQL by

postgres@boss:[~]$ psql -hlocalhost zabbix
psql (9.0.6, server 9.0.0)
Type "help" for help.

zabbix=#\dt             
 List of relations
 Schema |         Name          | Type  | Owner  
--------+-----------------------+-------+--------
 public | acknowledges          | table | public
 public | actions               | table | public
 public | alerts                | table | public
 public | applications          | table | public
 public | auditlog              | table | public
 public | auditlog_details      | table | public
 public | autoreg_host          | table | public 
 ....
....

here Owner of the relation is public, alter into zabbix by

its tedious to alter one by one through single alter statement by

postgres@boss:[~]$ psql -hlocalhost zabbix
psql (9.0.6, server 9.0.0)
Type "help" for help. 
 alter table  owner to zabbix;

instead of,  alter owner of the all relation in zabbix database in PostgreSQL by

postgres@boss:[~]$ for tbl in `psql -qAt -h localhost -c "select tablename from pg_tables where schemaname = 'public';" zabbix` ;
 do  psql -hlocalhost -c "alter table $tbl owner to zabbix" zabbix ; done
