MySQL Formula
=============
MySQL is the world's second most widely used open-source relational database
management system (RDBMS).
Sample Metadata
===============
Standalone setups
-----------------
Standalone MySQL server
.. code-block:: yaml
mysql:
server:
enabled: true
version: '5.5'
admin:
user: root
password: pass
bind:
address: '127.0.0.1'
port: 3306
database:
name:
encoding: 'utf8'
users:
- name: 'username'
password: 'password'
host: 'localhost'
rights: 'all privileges'
MySQL replication master with SSL
.. code-block:: yaml
mysql:
server:
enabled: true
version: 5.5
replication:
role: master
ssl:
enabled: true
authority: Org_CA
certificate: name_of_service
admin:
user: root
password: pass
bind:
address: '127.0.0.1'
port: 3306
MySQL replication slave with SSL
.. code-block:: yaml
mysql:

enabled: true
version: '5.5'
admin:
user: root
password: pass
bind:
address: '127.0.0.1'
port: 3306
key_buffer: 250M
max_allowed_packet: 32M

database:
name:
encoding: 'utf8'
users:
- name: 'username'
password: 'password'
host: 'localhost'
rights: 'all privileges'
MySQL Galera cluster
--------------------
MySQL Galera cluster is configured for ring connection between 3 nodes. Each
node should have just one member.
Galera initial server (master)
.. code-block:: yaml
mysql:
cluster:
enabled: true
name: openstack
role:master
bind:
address: 192.168.0.1
members:
- host: 192.168.0.1
port: 4567
user:
name: wsrep_sst
password: password
server:
enabled: true
version: 5.5
admin:
user: root
password: pass
bind:
address: 192.168.0.1
database:
name:
encoding: 'utf8'
users:
- name: 'username'
password: 'password'
host: 'localhost'
rights: 'all privileges'
MySQL client
------------
Database with initial data (Restore DB)
.. code-block:: yaml
mysql:
client:
server:
database:
admin:
host: localhost
port: 3306
user: ${_param:mysql_admin_user}
password: ${_param:mysql_admin_password}
encoding: utf8
database:
neutron_upgrade:
encoding: utf8
users:
- name: neutron
password: ${_param:mysql_neutron_password}
host: '%'
rights: all
- name: neutron
password: ${_param:mysql_neutron_password}
host: ${_param:single_address}
rights: all
initial_data:
engine: backupninja
source: ${_param:backupninja_backup_host}
host: ${linux:network:fqdn}
database: neutron
.. note:: This client role needs to be put directly on dbs node.
The provided setup restores db named neutron_upgrade with data from db called neutron.
Database management on remote MySQL server
.. code-block:: yaml
mysql:
client:
enabled: true
server:
server01:
admin:
host: database.host
port: 3306
user: root
password: password
encoding: utf8
database:
database01:
encoding: utf8
users:
- name: username
password: 'password'
host: 'localhost'
rights: 'all privileges'
User management on remote MySQL server
.. code-block:: yaml
mysql:
client:
enabled: true
server:
server01:
admin:
host: database.host
port: 3306
user: root
password: password
encoding: utf8
users:
- name: user01
host: "*"
password: 'sdgdsgdsgd'
- name: user02
host: "localhost"
Sample Usage
============
MySQL Galera check sripts
.. code-block:: bash
mysql> SHOW STATUS LIKE 'wsrep%';
mysql> SHOW STATUS LIKE 'wsrep_cluster_size' ;"
Galera monitoring command, performed from extra server
.. code-block:: bash
garbd -a gcomm://ipaddrofone:4567 -g my_wsrep_cluster -l /tmp/1.out -d
1. salt-call state.sls mysql
2. Comment everything starting wsrep* (wsrep_provider, wsrep_cluster, wsrep_sst)
3. service mysql start
4. run on each node mysql_secure_install and filling root password.
.. code-block:: bash
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 MySQL
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 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? [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] n
... 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? [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...
5. service mysql stop
6. uncomment all wsrep* lines except first server, where leave only in my.cnf wsrep_cluster_address='gcomm://';
7. start first node
8. Start third node which is connected to first one
9. Start second node which is connected to third one
10. After starting cluster, it must be change cluster address at first starting node without restart database and change config my.cnf.
.. code-block:: bash
mysql> SET GLOBAL wsrep_cluster_address='gcomm://10.0.0.2';
