How do I install and run MySQL version 5 database Server under OpenBSD UNIX operating systemm?

OpenBSD has pkg_add command. It is used to install packages created with the pkg_create command. Selected packages containing precompiled applications from the /usr/ports tree can be found on the OpenBSD FTP site. The pkg_add is the easiest way to install new packages, to replace existing packages with other flavors (option -r) or to update packages to newer versions option -u). Please note that MySQL server dropped from the latest version of OpenBSD and replaced by MariaDB server. MariaDB intends to maintain high compatibility with Oracle MySQL servers. It is a drop-in replacement for MySQL server on OpenBSD. I strongly suggest that you install and set up MariaDB server on OpenBSD.

How to install MySQL Database Server on OpenBSD

First setup installation mirror i.e. PKG_PATH using export command:
$ export PKG_PATH=ftp://mirror.planetunix.net/pub/OpenBSD/4.1/packages/`machine -a`/
Next install MySQL server, using pkg_add command, enter:
$ sudo pkg_add -i -v mysql-server
OR
# pkg_add -i -v mysql-server
Output:

--- mysql-server-5.0.33 -------------------
The mysql-server package doesn't initialize a default database.
Please run /usr/local/bin/mysql_install_db to create one.

Install default MySQL database

By default MySQL database is not initialized, enter the following command to create a default database:
# /usr/local/bin/mysql_install_db
Output:

Installing all prepared tables
Fill help tables
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/local/bin/mysqladmin -u root password 'new-password'
/usr/local/bin/mysqladmin -u root -h openbsd.nixcraft.in password 'new-password'
See the manual for more instructions.

Start MySQL server

Now you have MySQL server installed. Start the server daemon, enter:
# /usr/local/bin/mysqld_safe &
Output:

[1] 7750
Starting mysqld daemon with databases from /var/mysql

Connect to MySQL server

Run mysql command to test if everything is working fine, enter:
# mysql
Output:

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 1
Server version: 5.0.33-log OpenBSD port: mysql-server-5.0.33

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> quit
Bye

Set root password

You must set a password for the MySQL root user, enter:
# /usr/local/bin/mysqladmin -u root password 'YOUR-Secret-Password'
To access the MySQL server with password, enter:
$ mysql -u root -p

Create MySQL startup and stop script

Finally, you need a script to start and stop MySQL Server. In order to start MySQL server at boot time, enter following command in /etc/rc.conf.local file:
# vi /etc/rc.conf.local
Append following line:
mysql=YES
Save and close the file. Now you need to edit /etc/rc.local file. It is use to specify site-specific startup actions, daemons, and other things which can be done AFTER your system goes into securemode:
# vi /etc/rc.local
Find out line which read as follows:
# Add your local startup actions here.
Append following code:

# MySQL startup 
if [ X"${mysql}" == X"YES" -a -x /usr/local/bin/mysqld_safe ]; then
   echo -n " mysqld " 
   /usr/local/bin/mysqld_safe --user=_mysql &
fi

Save and close the file.

How do I stop MySQL server under OpenBSD?

Use mysqladmin command:
# mysqladmin -u root -p shutdown
