Discovering the Public Cloud

Connection

Servermysql-[account].alwaysdata.net
Port3306 (MySQL port by default)
Web interfacephpMyAdmin

The connection data depends on the relevant account. You can find the precise values in the administration interface section under Databases > MySQL.

Example with mysql

In our example, we use the SSH access and consider the following information:

  • Account name: foo
  • Database name: foo_base
  • We will use the default SSH users and databases, i.e. the ones created when the accounts are opened (e.g. foo for the foo account).
foo@ssh:~$ mysql -h mysql-foo.alwaysdata.net -u foo -p foo_base

Permissions

When you create your MySQL databases and users, you have the option of assigning the following permissions:

  • GRANT ALL PRIVILEGES,
  • GRANT READONLY,
  • No privileges.

If you change your user’s permissions via a third party application, any validation via the administration interface (or via the API) will reset the permissions in line with the directives above.

Restore a database from its daily backup

Several options :

  • use our backup recovery feature,

  • use the following command :

    $ xzcat $HOME/admin/backup/[date]/mysql/[database].sql.xz | mysql -h mysql-[account].alwaysdata.net -u [user] -p [database]
    
  • get the tarbal and use the client of your choice.

Other informations

The maximum number of simultaneous connections per user is 40. On request, it is possible to change this for VPS and dedicated servers.

MySQL blocks the size of the user name; if your account’s name is too long, an ID will be assigned to it. You will find this in Databases > MySQL > Users.

An ANALYZE TABLE is carried out daily on all your tables to guarantee good performance, but don’t hesitate to do it yourself when your data changes drastically, for example after importing a database.

To check the MariaDB configuration use the SQL query show variables.

MySQL events are not supported on alwaysdata’s servers.

In the public Cloud, you can change sql_mode by connection (SET SESSION).

MariaDB is offered by default on our servers but the VPS and dedicated users may request to use MySQL.
