pgAdmin is an open-source platform for managing PostgreSQL servers via GUI. It is a cross-platform solution that enables businesses to create, view, and modify PostgreSQL objects. It offers a simple and user-friendly web-UI to interact with the Postgres database sessions. If you are looking for an open-source administration panel for managing PostgreSQL, then pgAdmin is the best choice for you.

In this post, we will show you how to install pgAdmin on Arch Linux.

Step 1 – Configure Repository

By default, the default repository is outdated in Arch Linux, so you will need to modify the default mirror list. You can do it by editing the mirror list configuration file:

nano  /etc/pacman.d/mirrorlist

Remove all lines and add the following lines:

## Score: 0.7, United States
Server =$repo/os/$arch
## Score: 0.8, United States
Server =$repo/os/$arch
Server =$repo/os/$arch
## Score: 0.9, United Kingdom
Server =$repo/os/$arch
## Score: 1.5, United Kingdom
Server =$repo/os/$arch
Server =$repo/os/$arch
## Score: 6.6, United States
Server =$repo/os/$arch
## Score: 6.7, United States
Server =$repo/os/$arch
## Score: 6.8, United States
Server =$repo/os/$arch
## Score: 7.1, India
Server =$repo/os/$arch
## Score: 10.1, United States
Server =$repo/os/$arch

Save and close the file, then update all the package indexes with the following command:

pacman -Syu

Step 2 – Install PostgreSQL

By default, the PostgreSQL package is included in the Arch Linux main repository. You can install it using the following command:

pacman -S postgresql

Once the PostgreSQL is installed, you can verify the PostgreSQL version using the following command:

postgres --version

You will get the following output:

postgres (PostgreSQL) 15.1

Next, initialize the PostgreSQL database with the following command:

sudo -u postgres initdb --locale en_US.UTF-8 -D /var/lib/postgres/data

Next, start the PostgreSQL service using the following command.

systemctl start postgresql

By default, there is not any password for postgres user.

To set it, log in with Postgres user and set the password using the following command:

su - postgres
psql -c "alter user postgres with password 'password'"

Next, exit from the PostgreSQL shell with the following command.


Step 3 – Install pgAdmin

First, install the PIP package using the following command.

pacman -S python-pip

Next, update the setuptools package to the latest version.

python -m pip install --upgrade setuptools

Next, install the pgAdmin4 package using the PIP command.

pip install pgadmin4

Once pgAdmin is installed you can proceed to the next step.

Step 4 – Start pgAdmin

Next, run the following command to start the pgAdmin4.


You will be asked to set a user and password as shown below to start the server.

NOTE: Configuring authentication for SERVER mode.

Enter the email address and password to use for the initial pgAdmin user account:

Email address: [email protected]
Retype password:

* Serving Flask app ‘pgadmin’ (lazy loading)
* Environment: production
WARNING: This is a development server. Do not use it in a production deployment.
Use a production WSGI server instead.
* Debug mode: off

Note: Don’t do anything on this terminal because it will stop the pgAdmin4 server.

Step 5 – Install Nginx for pgAdmin4

At this point, pgAdmin is started and listens on port 5050. Now, you will need to configure Nginx as a reverse proxy to access the pgAdmin web UI.

Open another terminal and install the Nginx with the following command.

pacman -S nginx

Next, edit the Nginx configuration file:

nano /etc/nginx/nginx.conf

Add the following line above the last line:

server {
    listen 8080;

    server_name _;

    location / {

Save and close the file, then restart the Nginx service to apply the changes.

systemctl restart nginx

Step 6 – Access pgAdmin4 Web UI

Now, open your web browser and access the pgAdmin4 web interface using the URL http://your-server-ip:8080. You should see the pgAdmin4 login screen.
pgAdmin login page
Provide your email address and password and click on the Login button. You should see the pgAdmin default dashboard on the following screen:
pgAdmin dashboard page
Next, click on the Add New Server button. You should see the following screen:
pgAdmin define server name
In the General tab, provide the name of the server and click on the Connection tab. You should see the following screen:
pgAdmin connection page
Provide the Hostname or IP address of the server that you want to connect to, as well as the Port number, PostgreSQL username, and password, and click on the Save button. Once the connection has been established, you should see the detailed information about your PostgreSQL database in the left pane:
