I'm trying to set up a remotely accessible Postgres database . I want to host this databse on one Linux based device (HOST), and to access it on another Linux based device (CLIENT).
In my specific case, HOST is a desktop device running Ubuntu. CLIENT is a Chromebook with a Linux virtual system. (I know. But it's the closest thing to a Linux based device that I have to hand.
PGP_KEY_URL="https://www.postgresql.org/media/keys/ACCC4CF8.asc"
POSTGRES_URL_STEM="http://apt.postgresql.org/pub/repos/apt/"
POSTGRES_URL="$POSTGRES_URL_STEM `lsb_release -cs`-pgdg main"
POSTGRES_VERSION="12"
PGADMIN_URL_SHORT="https://www.pgadmin.org/static/packages_pgadmin_org.pub"
PGADMIN_URL_STEM="https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt"
PGADMIN_TO_ECHO="deb $PGADMIN_URL_STEM/`lsb_release -cs` pgadmin4 main"
PGADMIN_PATH="/etc/apt/sources.list.d/pgadmin4.list"
sudo apt install curl --yes
sudo apt install gnupg2 --yes
wget --quiet -O - $PGP_KEY_URL | sudo apt-key add -
echo "deb $POSTGRES_URL" | sudo tee /etc/apt/sources.list.d/pgdg.list
sudo apt install postgresql-$POSTGRES_VERSION --yes
sudo apt install postgresql-client-$POSTGRES_VERSION --yes
sudo curl $PGADMIN_URL_SHORT | sudo apt-key add
sudo sh -c "echo \"$PGADMIN_TO_ECHO\" > $PGADMIN_PATH && apt update"
sudo apt update
sudo apt install pgadmin4 --yes
NU_USERNAME="my_user"
NU_PASSWORD="guest"
NU_QUERY="CREATE USER $NU_USERNAME WITH superuser password '$NU_PASSWORD';"
sudo -u postgres psql -c "$NU_QUERY"
Host IP Address: 192.168.1.255
Port: 5432 (same as when I set up the database on HOST)
User: my_user
Password: guest
However, when I try to save the connection, PGAdmin responds after a few seconds saying that the connection has timed out .
You have to configure listen_addresses
in /var/lib/pgsql/data/postgresql.conf
like this:
listen_addresses = '*'
Next make sure your firewall doesn't block the connection by checking if telnet can connect to your server:
$ telnet 192.168.1.255 5432
Connected to 192.168.1.255.
Escape character is '^]'.
If you see Connected
network connectivity is ok. Next you have to configure access rights for remote hosts.
