How do I install MariaDB 10.3 on FreeBSD 12?, How to Install MariaDB 10.3 Database Server on FreeBSD 12?.  MariaDB 10.3 is a multi-user, multi-threaded SQL database server. It is a community-developed fork of the MySQL relational database management system.

MariaDB 10.3 Features:

• InnoDB is used as the default storage engine instead of XtraDB.
• System-versioned tables
• FOR loops
• MariaDB Galera Cluster, a synchronous multi-master cluster, is now a standard part of MariaDB.
• Sequences
• Instant ADD COLUMN for InnoDB
• Invisible columns
• Parallel replication
• Multi-source replication
• Common table expressions
• Storage-engine independent column compression

In my last article, I covered:

How to Install PHP 7.2 on FreeBSD 12

Below are the steps to install and configure MariaDB 10.3 on FreeBSD 12.

Step 1: Update ports tree

Start by updating your FreeBSD server Ports tree using the portsnap command:

$ jmutai@freebsd:~ % su -
 Password:
 root@freebsd:~# portsnap fetch update
 Looking up portsnap.FreeBSD.org mirrors… 5 mirrors found.
 Fetching public key from ec2-ap-southeast-2.portsnap.freebsd.org… done.
 Fetching snapshot tag from ec2-ap-southeast-2.portsnap.freebsd.org… done.
 Fetching snapshot metadata… done.
 Fetching snapshot generated at Sun Dec  9 00:19:28 UTC 2018:

 Fetching snapshot tag from ec2-ap-southeast-2.portsnap.freebsd.org… done.
 Fetching snapshot metadata… done.

 Fetching 0 metadata files… done.
 Fetching 78 patches. 
 (78/78) 100.00%  done.                                   
 done.
 Applying patches… 
 done.
 Fetching 3 new ports or files… done.
 /usr/ports was not created by portsnap.
 You must run 'portsnap extract' before running 'portsnap update'.

When running Portsnap for the first time, you need to extract the snapshot into /usr/ports:

sudo portsnap extract

You should get the message below at the end of the output.

Building new INDEX files... done.

Confirm that everything is up to date.

sudo portsnap fetch update

Step 2: Install MariaDB 10.3 Database Server

MariaDB 10.3 can be installed using binary or ports method. This installation is from the binary package using the pkgpackage manager.

Check if MariaDB 10.3 is available from your package cache:

$ pkg search mariadb | grep 10.3
mariadb103-client-10.3.11      Multithreaded SQL database (client)
mariadb103-server-10.3.11      Multithreaded SQL database (server)

From the output, we can see there is version 10.3.11 available. Install  both the server and client using the command below:

$ sudo pkg install mariadb103-server mariadb103-client
 Updating FreeBSD repository catalogue…
 FreeBSD repository is up to date.
 All repositories are up to date.
 The following 6 package(s) will be affected (of 0 checked):

Step 3: Start and Enable mysql-server service

After installing MariaDB Database server on FreeBSD 12 server, you’ll need to start the service before you can configure it.

Run the following command in your terminal to enable  themysql-server service to start on system boot.

$ sudo sysrc mysql_enable="YES"
mysql_enable:  -> YES

Then start the service.

sudo service mysql-server start

Step 4: Harden MariaDB server installation

Run the command mysql_secure_installation to harden MariaDB database server.

$ mysql_secure_installation
 NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
       SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
 In order to log into MariaDB to secure it, we'll need the current
 password for the root user.  If you've just installed MariaDB, and
 you haven't set the root password yet, the password will be blank,
 so you should just press enter here.
 Enter current password for root (enter for none): 
 OK, successfully used password, moving on…
 Setting the root password ensures that nobody can log into the MariaDB
 root user without the proper authorisation.
 Set root password? [Y/n] y
 New password: 
 Re-enter new password: 
 Password updated successfully!
 Reloading privilege tables..
  … Success!
 By default, a MariaDB installation has an anonymous user, allowing anyone
 to log into MariaDB without having to have a user account created for
 them.  This is intended only for testing, and to make the installation
 go a bit smoother.  You should remove them before moving into a
 production environment.
 Remove anonymous users? [Y/n] Y
  … Success!
 Normally, root should only be allowed to connect from 'localhost'.  This
 ensures that someone cannot guess at the root password from the network.
 Disallow root login remotely? [Y/n] Y
  … Success!
 By default, MariaDB comes with a database named 'test' that anyone can
 access.  This is also intended only for testing, and should be removed
 before moving into a production environment.
 Remove test database and access to it? [Y/n] Y
 Dropping test database…
 … Success!
 Removing privileges on test database…
 … Success! 
 Reloading the privilege tables will ensure that all changes made so far
 will take effect immediately.
 Reload privilege tables now? [Y/n] Y
  … Success!
 Cleaning up…
 All done!  If you've completed all of the above steps, your MariaDB
 installation should now be secure.
 Thanks for using MariaDB!

Ensure you:

• Set Database root user password
• Remove anonymous users
• Disallow root user remote logins
• Remove test database and access to it

When done, test access using the root user

$ mysql -u root -p
 Enter password: <Enter password>
 Welcome to the MariaDB monitor.  Commands end with ; or \g.
 Your MariaDB connection id is 17
 Server version: 10.3.11-MariaDB FreeBSD Ports
 Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
 Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
 MariaDB [(none)]> SELECT VERSION();
 +-----------------+
 | VERSION()       |
 +-----------------+

 +-----------------+

 MariaDB [(none)]> QUIT
 Bye

Step 5: Bind MariaDB Server service to localhost

By default, MariaDB service binds to all available network interfaces as can be seen from:

$ sockstat -4 -6 | grep 3306
mysql mysqld 1350 21 tcp46 *:3306 *:*

If you don’t have services connecting to your database server from the network, you can limit this to localhost.

# sysrc mysql_args="--bind-address=127.0.0.1"
mysql_args: -> --bind-address=127.0.0.1

You need to restart mysql-server after making this change

# service mysql-server restart
Stopping mysql.
Waiting for PIDS: 1350, 1350.
Starting mysql.

Verify the change:

# sockstat -4 -6 | grep mysql
mysql mysqld 1614 21 tcp4 127.0.0.1:3306 *:*
