Thread: troubleshooting suggestions requested
Greetings to all. I wonder if I might trouble you with a beginner's question.
I have a postgres installation that appears to be working correctly when I used psql to connect to it from the postgres
account. However, when I try to connect as postgres from other accounts, I can't connect. I think the password has
beenset correctly with ALTER USER from inside psql.
I get the error:
[rick@localhost javatest]$ e2:Connection refused. Check that the hostname and port are correct and that the postmaster
isaccepting TCP/IP connections.
Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP
connections.
at org.postgresql.jdbc1.AbstractJdbc1Connection.openConnection(AbstractJdbc1Connection.java:167)
at org.postgresql.Driver.connect(Driver.java:122)
at java.sql.DriverManager.getConnection(DriverManager.java:512)
at java.sql.DriverManager.getConnection(DriverManager.java:171)
at j5.<init>(j5.java:17)
at j5.main(j5.java:29)
and the relevant chunk of my code is:
final static private String _url = "jdbc:postgresql://localhost:5432/wombat1test";
j5() {
try {
Class.forName(_driver);
c = DriverManager.getConnection(_url, "postgres", "wombatpassport");
}
catch (java.sql.SQLException e2) {
System.out.println("e2:"+e2.toString());
e2.printStackTrace();
}
====
Clearly, there are quite a few things that could be wrong. I've been reading the documentation and archive, but my
troubleshootingingenuity is running low. If
anyone has any suggestions, I would be very grateful.
Thanks
Rick
Watch at the /usr/local/pgsql/data/pg_hba.conf
insert the lines like that at the end: (read the text in the file
before)
local all all
trust
host all all 0.0.0.0 0.0.0.0

hi,
take a look in to the file pg_hba.conf and be sure, that You are enabling
TCP/IP connections.

You also have to enable them in postgresql.conf or on the command line
