摘要:9个步骤通过API创建云服务器。
事情是这样的,公司成立了一个新项目,要给项目建官网,并搭建一个web服务器。按照我的习惯,搭建一个本地虚拟机就好了,部署简单方便还好配置,云服务器嘛,写了10年代码,还是不习惯那玩意儿。
我这刚开始动手,就看见实习生屁颠屁颠地跑过来,我心想这小子肯定是想来学虚拟机搭建部署的,这么简单的事都不会,真是白瞎了他那985的学校了。
可是...万万没想到啊,小实习生跑到我老大那里邀功去了!!!远远地听见他说:“公司新项目跑在云服务器上了,以后可以根据访问量随时进行弹性扩展,安全稳定还快。”
啥?云服务器?这小子居然会配置云服务器?听完汇报,老大看向了我,带着小实习生往我这边走过来……
“哼,叫你邀功,撞枪口上了吧,我就说云服务器配置没那么容易,还不是得来找我~”这么想着有点得意,老大走过来拍拍我的肩膀,说:“你跟他学一下怎么配置云服务器,别再用虚拟机了,以后都是麻烦事。”
我...他...让我跟一个实习生学???
实习生冲我微微一笑,就走了,没过一会扔给我一份文档,上面写着:“创建弹性云服务器流程详解”。打开粗略扫了一眼,代码都直接贴上来了?瞧不起谁?感觉有被冒犯到。
技术人嘛,看到代码还是没忍住跑一遍,等我发现bug或跑不通,再给他上上课!
结果……真香。
内容是这样的:
通过API创建云服务器的9个步骤(以指定镜像方式创建云服务器为例)
步骤一:确定待创建云服务器所在的可用区。
1、查询可用区。
(1)接口相关信息
URI格式:GET /v2.1/{project_id}/os-availability-zone
(2)请求示例
GET: https://{endpoint}/v2.1/74610f3a5ad941998e91f076297ecf27/os-availability-zone
(3)响应示例
{ "availabilityZoneInfo": [ { "hosts": null, "zoneState": { "available": true }, "zoneName":"zone_01" }, { "hosts": null, "zoneState": { "available": true }, "zoneName": "zone_01" } ] }
2、根据实际需要选择可用区,并记录可用区的zoneName。
步骤二:确定待创建云服务器的规格。
1、查询云服务器规格信息。
(1)接口相关信息
URI格式:GET/v2.1/{project_id}/flavors/detail{?minDisk,minRam,is_public,sort_key,sort_dir}
其中,“?”后的字段为查询规格时可选的查询检索参数。

2、 记录响应消息体中的name信息。如本例中为“demo2”。
步骤六:创建密钥对登录鉴权的云服务器。
(1)接口相关信息
URI格式:POST /v2.1/{project_id}/servers
说明:
本示例是指定image创建云服务器,因此:
● block_device_mapping_v2.1中,“source_type”需设置为“image”,“uuid”设置为选择的镜像ID,“destination_type”设置为“volume”,“boot_index”设置为“0”。
● “volume_size”应大于等于镜像元数据中指定的最小值。
(2)请求示例
POST: https://{endpoint}/v2.1/74610f3a5ad941998e91f076297ecf27/servers
Body:
{ "server": { "flavorRef": "c1.large", "name": "zttestvm1", "block_device_mapping_v2.1": [{ "source_type": "image", "destination_type": "volume", "volume_type": "SATA", "volume_size": "40", "delete_on_termination": "true", "uuid": "11e8f727-d439-4ed1-b3b8-33f46c0379c4", "boot_index": "0" }], "networks": [{ "uuid": "fb68519f-a7c0-476e-98d4-2e4cf6de6def" }], "key_name": "demo2", "availability_zone": "az_test_01" } }
(3)响应示例
{ "server": { "security_groups": [ { "name": "default" } ], "OS-DCF:diskConfig": "MANUAL", "links": [ { "rel": "self", "href": "https://None/v2.1/74610f3a5ad941998e91f076297ecf27/servers/6d311127-bce1-48db-bf0f-cac9f8f7f077" }, { "rel": "bookmark", "href": "https://None/74610f3a5ad941998e91f076297ecf27/servers/6d311127-bce1-48db-bf0f-cac9f8f7f077" } ], "id": "6d311127-bce1-48db-bf0f-cac9f8f7f077", "adminPass": "WcC4QoVZPXpV" } }
步骤七:设置密码登录方式。
(1)使用非cloud-init镜像创建云服务器时,Windows和Linux系统都使用“adminPass”参数实现密码注入。
(2)使用cloud-init镜像创建云服务器时:
l 对于Linux系统,只能使用“user_data”进行密码注入,“user_data”字符串长度小于65535,且必须是base64加密的;
l 对于Windows系统,只能通过元数据“admin_pass”进行密码注入。
步骤八:创建密码方式登录鉴权的弹性云服务器。
说明:
本示例是指定image创建弹性云服务器,因此:
(1)block_device_mapping_v2.1中,“source_type”需设置为“image”,“uuid”设置为选择的镜像ID,“destination_type”设置为“volume”,“boot_index”设置为“0”。
(2)“volume_size”应大于等于镜像元数据中指定的最小值。

按照步骤指示,我很快完成了云服务器的搭建,不禁有些惊讶,这小子怎么懂这么多?等等...华为云API Explorer?打开华为云API Explorer的官网,我好像打开了新世界的大门,有很多已配置好的环境和接口,直接调用调试就可以了,以后怕是没有什么能够难住我了!
目前API Explorer平台已开放EI企业智能、计算、应用服务、网络、软件开发平台、视频等70+云服务,共上线2000+个API、6000+个错误码。在前期试运行期间,华为云API Explorer平台上的API接口也已被多家企业成功接入。
点击查看详情:《华为云一站式API解决方案平台API Explorer上线》
据悉,华为云API Explorer平台在未来几个月会实现更多功能,比如支持SDK示例代码、CLI等特性,同时也会开放更多的云服务API接口,连接更多开发者实现创新、拓宽创新边界。
