Question

I got the package postgresql-8.4.9.tar.bz2 on the postgresql website and installed it following the instructions on the file INSTALL. But when we try to run it, it doesn’t work and throws this error:

/usr/local/pgsql/bin/postgres -D /usr/local/pgsql/data
LOG:  could not bind IPv6 socket: Address already in use
HINT:  Is another postmaster already running on port 5432? If not, wait a few seconds and retry.
LOG:  could not bind IPv4 socket: Address already in use
HINT:  Is another postmaster already running on port 5432? If not, wait a few seconds and retry.
WARNING:  could not create listen socket for "localhost"
FATAL:  could not create any TCP/IP sockets

I don’t know, maybe it’s because of some conflict with mysql. Does anybody know what’s going on?

Thanks in advance!

Answer 1

It appears that another process is listening on port 5432. Try running the following command:

 sudo netstat -tulpn | grep 5432
