odbc problem using PHP

Post by hkrenske » 2018/02/18 06:39:35

I am running postgresql on Centos 7 as well as hosting a website which uses data from the postgresql database. I am using PHP. Everytime I try to access any data from a browser screen it returns the following error:

Warning: odbc_connect(): SQL error: [unixODBC]Could not connect to the server; Could not connect to remote socket immedaitely, SQL state 08001 in SQLConnect in /var/www/html/_210db/dbms_fns.php on line 5

I would really appreciate some advice on how to correct the problem that I have encountered. If you need any other configuration files I will send them.

The web site used to work using centos 5.

Thanks for any help you can give me.

ODBC files are
/etc/odbcinst.ini
# Driver from the postgresql-odbc package
# Setup from the unixODBC package
[PostgreSQL]
Description = ODBC for PostgreSQL
Driver = /usr/lib/psqlodbc.so
Setup = /usr/lib/libodbcpsqlS.so
Driver64 = /usr/lib64/psqlodbcw.so
#Driver64 = /usr/lib64/libodbcpsqlS.so.2.0.0
Setup64 = /usr/lib64/libodbcpsqlS.so
FileUsage = 1

/etc/odbc.ini
[rbcn]
Description = Environment database
Driver = PostgreSQL
Trace = 1
TraceFile = /var/log/sql.log
Database = rbcn
Servername = gudgeon2
Username = tell
Password = tell.01
Port = 5432
Protocol = 6.4
ReadOnly = No
RowVersioning = No
ShowSystemTables = No
ShowOidColumn = No
FakeOidIndex = No
ConnSettings =

Runnning some tests have produced the following results:
# isql -v rbcn

Thank you so much. I have struggled with this for days. Now in my 70s, I support local environment groups with a way that they can collectively record the work they have done and easily search on historic data. I presume that by leaving out the -P in the line will make the change permanent across reboots.
Again many thanks.

The opposite, the -P makes it permanent, without it it only lasts for one boot.
