===== Procedimento para instalar o BD MySQL no FreeBSD =====

=== 1 - Vamos para a instalação do BD mysql: ===

<code>
root@glpi:/usr/local/etc # pkg search mysql

mysql55-server-5.5.60          Multithreaded SQL database (server)
mysql56-server-5.6.41          Multithreaded SQL database (server)
mysql57-server-5.7.23_1        Multithreaded SQL database (server)
mysql80-server-8.0.12          Multithreaded SQL database (server)
</code>

=== 2 - Encontre as linha a linha a qual diz respeito a instalação do serviço de Banco de Dados mysql: ===

- No meu caso encontrei quatro versões, vou usar a penúltima, versão 5.7:

<code>
root@glpi:/usr/local/etc # pkg install mysql57-server-5.7.23_1
</code>

3 - Após o termino da instalação do mysql, vamos configurar o serviço no /etc/rc.conf e estartar o serviço. Se a instalação estiver sido correta, ele deve iniciar normalmente:

<code>
root@glpi:/usr/local/etc # /usr/local/etc/rc.d/mysql-server enable
</code>

-- Foi acrescentado a linha que inicia o serviço na hora do boot mysql_enable="YES", agora vamos levantar o serviço.
<code>
root@glpi:/usr/local/etc # /usr/local/etc/rc.d/mysql-server start
Starting mysql.

</code>

-- Agora vamos ver se o serviço está rodando:

<code>
root@glpi:/usr/local/etc # sockstat -4l
USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS
mysql    mysqld     83282 22 tcp4   127.0.0.1:3306        *:*

</code>

-- Como podemos ver, o apache e o mysql já estão funcionando:

-- O mysql está rodando no endereço 127.0.0.1. Teremos que alterar para o endereço ip da máquina, vamos ter que editar o arquivo /usr/local/etc/mysql/my.cnf

<code>
root@glpi:/usr/local/etc/mysql # ee my.cnf

=== 4 - Vamos preparar a configuração padrão do MySQL. Precisamos atribuir uma senha para a conta root do mysql, usaremos o comando "mysql_secure_installation", ele vai nos dar algumas opções como: ===

<code>
root@glpi:/usr/local/etc/mysql # mysql_secure_installation
</code>

-- Nas opções que virão a seguir, siga essas instruções (resumo):

<code>
1 - Change the password for root ? (Alterar a senha do root?) ((Press y|Y for Yes, any other key for No) :  
2 - Remove anonymous users? (Remover usuário anônimos?) (Press y|Y for Yes, any other key for No) : y
3 - Disallow root login remotely? (Desabilitar login remoto?) (Press y|Y for Yes, any other key for No) :
4 - Disallow root login remotely? (Desabilitar login de root remoto?)(Press y|Y for Yes, any other key for No) :
5 - Remove test database and access to it? (Remover banco de dados de testes e acesso a eles?) (Press y|Y for Yes, any other key for No) : y
6 - Reload privilege tables now? (Recarregue as tabelas de privilégios agora))(Press y|Y for Yes, any other key for No) : y
</code>

Securing the MySQL server deployment.

Connecting to MySQL server using password in '/root/.mysql_secret'

VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?

Press y|Y for Yes, any other key for No:
Using existing password for root.
Change the password for root ? ((Press y|Y for Yes, any other key for No) : y
New password:

Re-enter new password:
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL 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? (Press y|Y for Yes, any other key for No) : 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? (Press y|Y for Yes, any other key for No) :

 ... skipping.
By default, MySQL 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? (Press y|Y for Yes, any other key for No) : 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? (Press y|Y for Yes, any other key for No) : y
Success.

All done!
