Azure Database for MySQL - Single Server
Important
Azure Database for MySQL single server is on the retirement path. We strongly recommend that you upgrade to Azure Database for MySQL flexible server. For more information about migrating to Azure Database for MySQL flexible server, see What's happening to Azure Database for MySQL Single Server?
This article shows you how to manage your Single servers deployed in Azure. Management tasks include compute and storage scaling, admin password reset, and viewing server details.
Prerequisites
If you don't have an Azure subscription, create a free account before you begin. This article requires that you're running the Azure CLI version 2.0 or later locally. To see the version installed, run the az --version command. If you need to install or upgrade, see Install Azure CLI.
You'll need to log in to your account using the az login command. Note the id property, which refers to Subscription ID for your Azure account.
az login
Select the specific subscription under your account using az account set command. Make a note of the id value from the az login output to use as the value for subscription argument in the command. If you have multiple subscriptions, choose the appropriate subscription in which the resource should be billed. To get all your subscription, use az account list.
az account set --subscription <subscription id>
If you have not already created a server , refer to this quickstart to create one.
Scale compute and storage
You can scale up your pricing tier , compute and storage easily using the following command. You can see all the server operation you can perform az mysql server overview
az mysql server update --resource-group myresourcegroup --name mydemoserver --sku-name GP_Gen5_4 --storage-size 6144
Here are the details for arguments above :
| Setting | Sample value | Description |
|---|---|---|
| name | mydemoserver | Enter a unique name for your Azure Database for MySQL server. The server name can contain only lowercase letters, numbers, and the hyphen (-) character. It must contain from 3 to 63 characters. |
| resource-group | myresourcegroup | Provide the name of the Azure resource group. |
| sku-name | GP_Gen5_2 | Enter the name of the pricing tier and compute configuration. Follows the convention {pricing tier}{compute generation}{vCores} in shorthand. See the pricing tiers for more information. |
| storage-size | 6144 | The storage capacity of the server (unit is megabytes). Minimum 5120 and increases in 1024 increments. |
Important
- Storage can be scaled up (however, you cannot scale storage down)
- Scaling up from Basic to General purpose or Memory optimized pricing tier is not supported. You can manually scale up with either using a bash script or using MySQL Workbench
Manage MySQL databases on a server
You can use any of these commands to create, delete , list and view database properties of a database on your server
| Cmdlet | Usage | Description |
|---|---|---|
| az mysql db create | az mysql db create -g myresourcegroup -s mydemoserver -n mydatabasename |
Creates a database |
| az mysql db delete | az mysql db delete -g myresourcegroup -s mydemoserver -n mydatabasename |
Delete your database from your server. This command does not delete your server. |
| az mysql db list | az mysql db list -g myresourcegroup -s mydemoserver |
lists all the databases on the server |
| az mysql db show | az mysql db show -g myresourcegroup -s mydemoserver -n mydatabasename |
Shows more details of the database |
Update admin password
You can change the administrator role's password with this command
az mysql server update --resource-group myresourcegroup --name mydemoserver --admin-password <new-password>
Important
Make sure password is minimum 8 characters and maximum 128 characters. Password must contain characters from three of the following categories: English uppercase letters, English lowercase letters, numbers, and non-alphanumeric characters.
