The proxysql module installs, configures and manages the ProxySQL service.
This module will install the ProxySQL and manage it's configuration. It also extends Puppet to be able to manage mysql_users, mysql_servers, mysql_replication_hostgroups, mysql_galera_hostgroups, mysql_query_rules, proxysql_servers, scheduler and global_variables.
The module requires Puppet 5.5.8 and above. It also depends on:
- puppetlabs/mysql
- puppetlabs/apt - (Not strictly required on non Debian based systems)
- puppetlabs/stdlib
- camptocamp/systemd
For up to date details on external dependencies, please see the metadata.json or for released versions, the puppet forge page.
puppet/selinux is an optional soft dependency and not even listed in the metadata.json. No Operating Systems require this module to be present, but if it is, it will be used to install SELinux rules that allow logrotate to work. See manage_selinux
To install the ProxySQL software with all the default options:
include proxysqlBy default, packages come from the official upstream package repositories which the module will configure. On new installations, (by default), the 2.7.x repository will be configured. If ProxySQL is already installed, then the repository matching the currently installed version will be used.
To use your Operating System's own packages set manage_repo => false.
class { 'proxysql':
manage_repo => false,
}or you can configure your own repository by eg. declaring your own yumrepo, pulp_rpmbind or rhn_channel resource and setting manage_repo => false.
For example, using pulp and katello/pulp
pulp_rpmbind { 'my_proxysql_repo':}
class { 'proxysql':
manage_repo => false,
require => Pulp_rpmbind['my_proxysql_repo'],
}Alternatively, you can specify a package_source and associated options. This mimics the old, (pre version 4), behaviour of this module.
class { 'proxysql':
package_source => 'https://github.com/sysown/proxysql/releases/download/v1.4.11/proxysql_1.4.11-debian9_amd64.deb',
package_checksum_value => '65a3c2b98eefa42946ee59eef18ba18534c2a39d',
package_checksum_type => 'sha1',
}You can customize options such as (but not limited to) listen_port, admin_password, monitor_password, ...
class { 'proxysql':
listen_port => 3306,
admin_password => Sensitive('654321'),
monitor_password => Sensitive('123456'),
override_config_settings => $override_settings,
}You can configure users\hostgroups\rules\schedulers using class parameters
class { 'proxysql':
mysql_servers => [
{
'db1' => {
'port' => 3306,
'hostgroup_id' => 1,
}
},
{

}
},
],
mysql_users => [
{

{

{
'scheduler-1' => {

class { 'proxysql':
listen_port => 3306,
admin_password => Sensitive('SuperSecretPassword'),
}

}Configuration is done by the proxysql class.
You can override any configuration setting by using the override_config_settings hash. This hash resembles the structure of the proxysql.cnf file
{
admin_variables => {
refresh_interval => 2000,
...
},
mysql_variables => {
monitor_writer_is_also_reader => false,
...
},
mysql_servers => {
'127.0.0.1:33061-1' => {
'address' => '127.0.0.1',
'port' => 33061,
'hostgroup_id' => 1,
},
'127.0.0.1:33062-1' => {
'address' => '127.0.0.1',
'port' => 33062,
'hostgroup_id' => 1,
},
...
},
mysql_users => { ... },
mysql_query_rules => { ... },
scheduler => { ... },
mysql_replication_hostgroups => { ... },
mysql_galera_hostgroups => { ... },
}see REFERENCE.md
This module ships a fact that you may find useful in your profiles. It is not used by the module itself.
The proxysql_runtime fact queries ProxySQL and returns a hash containing the contents of several of the runtime tables.
The fact will only return data if the mysql2 library is installed in your puppet agent's gem environment.
For systems using official puppet packages, (All In One packages), the following code can be used to install this gem and make the fact available.
$dev_packages = ['mariadb-devel','make','gcc']
ensure_packages($dev_packages)
package { 'mysql2 gem':
ensure => present,
name => 'mysql',
provider => 'puppet_gem',
require => Package[$dev_packages],
}The module requires Puppet 5.5 or above. The proxysql_runtime fact only works when using the default value for mycnf_file_name.
