5. 在左侧权限策略名称列表下，单击AliyunECSFullAccess, AliyunESSFullAccess, AliyunOOSFullAccess, AliyunOSSFullAccess。
6. 单击确定。
7. 单击完成。

3.安装阿里云CLI。

brew install aliyun-cli           

4.配置CLI。

aliyun configure           

5.验证CLI可用，若可用，可在终端看到输出当前支持的多个地域。

aliyun ecs DescribeRegions           

通过CLI执行滚动升级

1.通过更新镜像滚动升级。

模板详情

执行命令如下：

aliyun oos StartExecution --TemplateName ACS-ESS-RollingUpdateByReplaceSystemDiskInScalingGroup --Parameters '{
                "invokeType": "invoke",
                "imageId": "centos_7_8_amd_x64_20G_alibase_20200806.vhd",
                "sourceImageId": "centos_8_2_x64_20G_alibase_20200717.vhd",
                "OOSAssumeRole": "",
                "exitProcess": [],
                "scalingConfigurationId": "asc-bp14e7lqyl66ca4rp4rb",
                "enterProcess": [
                    "ScaleIn",
                    "ScaleOut",
                    "HealthCheck",
                    "AlarmNotification",
                    "ScheduledAction"
                ],
                "scalingGroupId": "asg-bp1cjeuvlt1e1i1t",
                "batchNumber": 2,
                "batchPauseOption": "Automatic"
            }'           

回滚命令如下：

aliyun oos StartExecution --TemplateName ACS-ESS-RollingUpdateByReplaceSystemDiskInScalingGroup --Parameters '{
                "invokeType": "rollback",
                "sourceImageId": "centos_8_2_x64_20G_alibase_20200717.vhd",
                "OOSAssumeRole": "",
                "scalingConfigurationId": "asc-bp14e7lqyl66ca4rp4rb",
                "scalingGroupId": "asg-bp1cjeuvlt1e1i1t",

                "batchPauseOption": "Automatic"
            }'           

2.通过脚本执行滚动升级。

aliyun oos StartExecution --TemplateName ACS-ESS-RollingUpdateByRunCommandInScalingGroup --Parameters '{
                "invokeType": "invoke",
                "commandType": "RunShellScript",
                "OOSAssumeRole": "",
                "exitProcess": [],
                "invokeScript": "df -h\nifconfig",
                "rollbackScript": "df -h\nifconfig",

                "batchNumber": 2,
                "batchPauseOption": "Automatic"
            }'           

aliyun oos StartExecution --TemplateName ACS-ESS-RollingUpdateByConfigureOOSPackage --Parameters '{
                "invokeType": "rollback",
                "OOSAssumeRole": "",
                "packageVersion": "v3",
                "packageName": "wordpress",
