[APPLIES TO: Azure Database for MySQL - Single Server Azure Database for MySQL - Flexible Server

This sample CLI script lists all available configuration parameters as well as their allowable values for Azure Database for MySQL server, and sets the innodb_lock_wait_timeout to a value that is other than the default one.

Prerequisites

  • This article requires version 2.0 or later of the Azure CLI. If using Azure Cloud Shell, the latest version is already installed.

Sample script

In this sample script, edit the highlighted lines to update the admin username and password to your own.

#!/bin/bash

# Create a resource group
az group create \
--name myresourcegroup \
--location westus

# Create a MySQL server in the resource group
# Name of a server maps to DNS name and is thus required to be globally unique in Azure.
# Substitute the <server_admin_password> with your own value.
az mysql server create \
--name mydemoserver \
--resource-group myresourcegroup \
--location westus \
--admin-user myadmin \
--admin-password <server_admin_password> \
--sku-name GP_Gen4_2 \

# Display all available configurations with valid values of an Azure Database for MySQL server
az mysql server configuration list \
--resource-group myresourcegroup \
--server-name mydemoserver

# Set value of *innodb_lock_wait_timeout*
az mysql server configuration set \
--resource-group myresourcegroup \

--value 120
