I am wondering if it is possible while using MAMP to have the database online?
I am developing a couple sites locally between work and home, and initially thought I could get mamp to store or point to my external drive. No bueno.
SO am thinking I can still run mamp at work or at home pointing to my external drive but the DB that it would connect to would be online?
Depending on your system you could set up an SSH tunnel to another computer running the database. SSH tunneling allows you to direct a port on your computer (For example port 8889 which MAMP uses by default for the MySQL port) to a port on another computer. If set up correctly, you tell MAMP that you are using local port 8889, but ssh will then direct all traffic to the remote computer's mySQL port which is where you could run your database. This link has a good tutorial on how to do this provided that you have ssh installed.

Sorry for the very elementary question.
I created a simple web app that connects with a database for learning.
PostgreSQL is using 13.
Right now, I'm running both the database and the application on my local PC, but I wanted to see if I could view this application from another PC.
The application will be created in C# and Blazor, and the connection to the database will be made using NpgSQL.
We can connect the application and database with localhost within the local PC, but we cannot connect with localhost from other PCs, so we want to change the host of PostgreSQL to an IP address.
I'm thinking of connecting a local PC (say A) and another PC (say B).
Connect the Lan cable directly to both PCs and place them under the same network.
Set the IP address temporarily as follows.
A is 192.168.1.1
B is 192.168.1.10
In this case, if I set the database connection string in the application to 192.168.1.1, am I correct in understanding that I can reference the database from both PC(A) and PC(B)?
Sorry I don't have the environment to verify this right now.
I have 2 computers (Win 10 and Mac) and need to access a RDS Postgres database. Connection is secure via a bastion host and ecs instance. When I configure TablePlus like this:
It works perfectly on the Mac but not on Windows. I checked a bit and recommendation is to create a tunnel via Putty to forward the port 5432 to a local one and then try to access the db with a local IP. But no success.
I would like to know if there is a specific setting in TablePlus or something I'm missing that will allow me to access the database on my Windows computer? I tried also with pgAdmin and same results.
I am running postgresql in WSL Ubuntu on windows. Everything is up to speed, my data is loaded and I wish to access the database through some graphical interface. I was thinking pgadmin4.
Is it possible to accomplish this through a windows install of pgadmin4? I installed pgadmin4 on windows and tried to connect the traditional way in the GUI through localhost but am not getting a connection. I figure there may be a special method here.
For everyone else stumbling across this: The best way to do this (that I know of) is to SSH into your local WSL and then configure the SSH in pgAdmin to that.
I have yet to figure out, how to use this remotely.
As long as postgres is running within your wsl2 instance (check with sudo service postgresql status) then within PgAdmin 4 (running in windows), all you need to do is click to "Register" a new server.
Then, while entering the Connection data, set host to localhost and port to 5432 (unless you specified unique port within your postgres instance when creating in wsl2.
See this answer for more detail
There is no special way needed, you should be able to get a connection. Just like your dev http ports are exposed to your browser on Windows, your db port should too.
I had to manually add localhost to pg admin though which is a bit weird.
Make sure your db service is up and running on Ubuntu, sometimes the db service is killed for no reason.
To see if your PostgresSQL service is up or not:
sudo service postgresql status
If it's not, start the service:
sudo service postgresql start
I am running openerp(odoo) application from amazon cloud server using putty and it is ubuntu Headless(NO GUI) server. PostgreSQL is the database used for this application. Right now I am only able to access it in command mode as there is no gui in Putty. In Windows, I have installed pgadmin3. Is it possible to access it from here by configuring?
You can configure your security group to open up the postgres port accessible from your IP address (I would highly recommend the access to be limited that way). After that you can just point your GUI client the external IP address of your instance using the port where the service is running on.
I suggest you to use pgadmin gui tool to access postgres database.
You can set up an SSH tunnel in putty and use that to access the remote database with your local pgadmin3. This is a very good and secure way to do things.
First, in Putty (Connection / SSH / Tunnels) add a source port of your choice, 5000 for example. Then enter localhost:5432 for Destination (providing postgres is running on port 5432 on the server). Press Add and save your session. Next time you open your ssh connection with Putty, the tunnel will be active.
After this, set up a new connection in pgadmin3, Host: localhost and Port: 5000 (and your username and pasword, of course). Now, if the putty session is active, you should be able to connect.
In postgresql.conf file, find a line called
listen_addresses = 'localhost' and change it to '*'
Next in pg_hba.conf add this line in IPV4 local connections,
host all all (Your external ip address in CIDR format) trust
Finally restart the database using this command,sudo service postgresql restart
I have a Postgres database on a linux server. I have root access which in turn can give me access to the database. In Windows you get PGAdminIII, which I would love to use to connect to the Linux server. I heard that tunneling might be necessary. I am not sure if that is true, or what it is really. Can anyone shed some light on the easiest way to get access to the database?
Tunneling is not strictly necessary. As long as you have port 5432 not firewalled, you should be able to connect to your Linux PostgreSQL server without much trouble.
You can check this from your Windows box by using this command from cmd console:
telnet linuxbox 5432
If you get black screen (not an error), then everything looks good and port 5432 should be open. Note that on Windows 7 you may need to enable telnet client (it is disabled by default) using this command:
pkgmgr /iu:"TelnetClient"
If your server is not located in your local network, or if you are concerned about security like somebody using network sniffer to watch your traffic, you should configure SSL/TLS on your PostgreSQL server - it is not very difficult to do, and completely free when using self-signed certificate.
Note that by default Postgres on Linux does not listen on network interfaces, you may need to enable it by editing postgresql.conf.
