备注

将要查看的是 Azure Database for MySQL 的新服务。You are viewing the new service of Azure Database for MySQL. 若要查看经典 MySQL Database for Azure 的文档,请访问此页To view the documentation for classic MySQL Database for Azure, please visit this page.

此示例 CLI 脚本列出了 Azure 数据库所有适用于 MySQL 服务器的可用配置参数及其允许的值,并将 innodb_lock_wait_timeout 设置为默认值以外的值。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.

先决条件Prerequisites

    • 如果使用的是本地安装,请使用 az login 命令登录到 Azure CLI。If you're using a local installation, sign in to the Azure CLI by using the az login command. 若要完成身份验证过程,请遵循终端中显示的步骤。To finish the authentication process, follow the steps displayed in your terminal. 有关其他登录选项,请参阅登录 Azure CLIFor additional sign-in options, see Sign in with the Azure CLI.

    • 出现提示时,请在首次使用时安装 Azure CLI 扩展。When you're prompted, install Azure CLI extensions on first use. 有关扩展详细信息,请参阅使用 Azure CLI 的扩展For more information about extensions, see Use extensions with the Azure CLI.

    • 运行 az version 以查找安装的版本和依赖库。Run az version to find the version and dependent libraries that are installed. 若要升级到最新版本,请运行 az upgradeTo upgrade to the latest version, run az upgrade.

  • 本文需要 Azure CLI 版本 2.0 或更高版本。This article requires version 2.0 or later of the Azure CLI.

示例脚本Sample script

在此示例脚本中,编辑突出显示的行,将管理员用户名和密码更新为你自己的。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 chinaeast2

# 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 chinaeast2 \
--admin-user myadmin \
--admin-password <server_admin_password> \
--sku-name GP_Gen5_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 \
--server-name mydemoserver \
--name innodb_lock_wait_timeout \
--value 120

# Check the value of *innodb_lock_wait_timeout*
az mysql server configuration show \
--resource-group myresourcegroup \
--server-name mydemoserver \
--name innodb_lock_wait_timeout
