This page is part of the 'build MineOS CRUX-from-the-ground-up series'. The information here is provided for comprehensiveness in documenting the steps in creating MineOS CRUX from CRUX Linux 2.7. These steps are already automated in the mainline release ISO.

Youtube walk-through

Securing MySQL and installing phpMyAdmin

Securing MySQL

The MySQL password is not set by default (blank), and can only be set when the MySQL daemon is running (upon first boot). To set the password, execute the following command:

As root:
mysql_secure_installation

Disabling MySQL

If you are certain you have no need for MySQL, either for websites or for your Minecraft server mods, you may remove it from the services list.

As root:
vi /etc/rc.conf
Remove mysqld from the list

PhpMyAdmin

PhpMyAdmin is available as an addon. To install, ensure you have first secured MySQL. Then, follow the steps to download and install PhpMyAdmin from its wiki page.

Enabling remote access/TCP-IP connectivity

Remote access/TCP-IP connectivity is disabled by default on installs <= 0.4.6--later versions can ignore this step as it has already been automated. All these actions must be done as root:

Edit the /etc/my.cnf file and comment out the line: 

<syntaxhighlight lang="bash">
  1. skip-networking

</syntaxhighlight>

Edit the hosts.allow file as well to add the mysqld daemon: 

<syntaxhighlight lang="bash">

mysqld: ALL SSHD: ALL </syntaxhighlight>

Have all localhost generated packets accepted by default in iptables:

As root:
iptables -A INPUT -i lo -j ACCEPT iptables-save > /etc/iptables-rules

You will need to restart the mysqld daemon for these changes to take effect.

As root:
/etc/rc.d/mysqld restart
