Introduction: Understanding SSL/TLS for PostgreSQL on Ubuntu‌ 18.04
SSL/TLS (Secure Sockets Layer/Transport⁢ Layer‍ Security) provides secure communication for PostgreSQL databases on⁣ Ubuntu 18., ensuring the ‍confidentiality and integrity of data transmitted over⁢ a network. In this tutorial, we will walk through the⁢ process of setting up SSL/TLS for PostgreSQL on ​Ubuntu⁢ 18., ⁣step-by-step. By the end of this guide, you will have a secure connection ⁣established between your PostgreSQL server and clients.

To begin,⁢ we need​ to⁢ generate a self-signed SSL certificate. This certificate⁢ will act as⁤ a root certificate authority⁣ (CA) for⁤ our PostgreSQL server. Open​ a terminal and run the following command ‌to create a new directory to store the SSL-related files:

mkdir ~/ssl

Next, navigate to the newly created directory by executing the command:

cd ~/ssl

Now, let’s generate the self-signed certificate using OpenSSL. Run the following command, replacing “yourservername” with the desired hostname or IP address of your PostgreSQL server:

openssl req -new ‍-x509 -nodes -text -out​ server.crt -keyout server.key -subj “/CN=yourservername”

Once the certificate ⁣and key are generated, we need to change their permissions to restrict access. Run the following commands:

chmod 600 ⁣server.key
chmod 600 ‍server.crt

Now ⁢that we have our SSL ‌certificate, we can move on ⁢to configuring ‌PostgreSQL ⁢to use SSL/TLS. Open the PostgreSQL configuration file by executing the command:

sudo nano‌ /etc/postgresql/12/main/postgresql.conf

In the configuration file, locate the section labeled “Connections and Authentication” and add the following lines:

# Enable SSL
ssl = on
ssl_cert_file = ‘/home/yourusername/ssl/server.crt’
ssl_key_file = ‘/home/yourusername/ssl/server.key’
ssl_ca_file = ”
ssl_crl_file = ”

Save​ and ​close the file. Finally, restart the PostgreSQL service to apply the changes:

sudo​ service postgresql restart

Now, your PostgreSQL server is configured to use SSL/TLS for⁣ secure communication. Clients connecting to the⁢ server will need to provide the appropriate SSL certificate to establish a secure connection. In the next section, we will explore how to configure client authentication for SSL/TLS in PostgreSQL.

  • Checking SSL⁣ Support: Before configuring SSL/TLS, it is ‌essential to ensure that your PostgreSQL installation⁢ supports it. You can check this by running the command postgres -h localhost -p 5432 -U postgres -l. Look for a line that includes “SSL support: true”. If the output shows “SSL support: false”, you will need to install​ additional packages or recompile PostgreSQL with SSL ‌support enabled.
  • Obtaining a⁣ SSL Certificate: To establish a secure connection, you will need an SSL certificate. You can ​either generate a self-signed certificate or​ obtain a certificate from a trusted certificate authority (CA). For testing or development purposes,‌ a self-signed certificate can be generated using the following command: openssl req -new -x509 -sha256 -nodes -out postgres.crt -keyout postgres.key -days 365.
  • Enabling SSL: To enable SSL/TLS for PostgreSQL, modify the postgresql.conf file and ‌set ‍the​ ssl = on parameter. Additionally, specify ‌the location of⁤ the SSL certificate and private key by setting the ssl_cert_file and ssl_key_file parameters to the respective file paths. Save the changes and restart PostgreSQL ‌to apply the configuration.
  • Verifying SSL Configuration: After enabling SSL, you can verify the configuration by connecting to‌ PostgreSQL using the psql command with the sslmode=require option. For example, psql "sslmode=require host=localhost port=5432 dbname=mydb user=myuser password=mypassword". If the connection is successful, it means SSL/TLS is configured correctly.
  • Additional Security Measures: ‌ In addition to configuring SSL/TLS, it is ​recommended to enforce strong authentication and access control measures. This includes implementing password policies, utilizing secure connections for client applications, and regularly updating PostgreSQL to ​benefit from security patches and improvements.
