The implementation of SSL in an MySQL server encrypts all data going back and forth between a server and a client, thereby preventing potential eavesdropping or data sniffing in wide area networks or within data centers. In addition, SSL also provides identify verification by means of SSL certificates, which can protect users against possible phishing attacks.

Note that the same procedure is also applicable to MariaDB server. First, create a temporary working directory where we will keep the key and certificate files. To check if OpenSSL is installed, use the following command.

The following commands will create ca-key. It does not matter what you put in these field. Just fill out those fields. The next step is to create a private key for the server. Next, export the server's private key to RSA-type key with this command below.

4 days ago · PostgreSQL uses Write-Ahead Logging (WAL), which provides atomicity and durability two of the ACID properties by default.
