9. MySQL Client
Deploying mysql client is very straight forward.
/etc/puppet/manifests/site.pp
node 'client.olindata.com' {
class { 'mysql::client': }
}

10. MySQL Server
Deploying mysql server is as simple as including mysql server
class.
/etc/puppet/modules/profile/manifests/mysql.pp
class profile::mysql {
class { '::mysql::server':
root_password => 'strongpassword',
override_options => { 'mysqld' => {
'max_connections' => '1024' } }
}
}

11. /etc/puppet/modules/role/manifests/database.pp
class role::database {
include profile::mysql
}
/etc/puppet/manifests/site.pp
node 'client.olindata.com' {
class { 'mysql::client': }
}
node 'server.olindata.com' {
include role::database
}

12. Creating mysql database
• MySQL Server alone is nothing without mysql database.
/etc/puppet/modules/profile/manifests/mysql.pp
mysql::db { 'mydb':
user => 'admin',
password => 'secret',
host => 'client.olindata.com ',
}

13. MySQL User
• We need to configure user and grants, so we are able to
provide permissions to the state of the table.
/etc/puppet/modules/profile/manifests/mysql.pp
mysql_user { 'root@127.0.0.1':
ensure => 'present',
max_connections_per_hour => '100',
max_queries_per_hour => '200',
max_updates_per_hour => '200',
max_user_connections => '80',
}

14. MySQL Grants
• Grants are the privileges, provided to access the
database/tables
/etc/puppet/modules/profile/manifests/mysql.pp
mysql_grant { 'root@localhost/*.*':
ensure => 'present',
options => ['GRANT'],
privileges => ['ALL'],
table => '*.*',
user => 'root@localhost',
}

15. MySQL Flavour Install
• Other mysql flavours like MariaDB, Percona can be installed
with the existing module ‘puppetlabs-mysql’
/etc/puppet/modules/profile/manifests/mysql.pp
class profile::mysql {
class { '::mysql::server':
package_ensure => 'present',
package_name => 'mariadb-server',
}
}
