操作步驟

1. 創(chuàng)建專(zhuān)有網(wǎng)絡(luò)和交換機(jī)。本示例中在cn-hangzhou-b區(qū)域創(chuàng)建了一個(gè)專(zhuān)有網(wǎng)絡(luò)和交換機(jī)。

   1. 創(chuàng)建terraform.tf文件，輸入以下內(nèi)容，并保存在當(dāng)前的執(zhí)行目錄中。

      variable "region" {
        default = "cn-hangzhou"
      }
      
      provider "alicloud" {
        region = var.region
      }
      
      data "alicloud_zones" "default" {
        available_resource_creation = "VSwitch"
      }
      
      resource "alicloud_vpc" "main" {
        vpc_name = "alicloud"
        # 專(zhuān)有網(wǎng)絡(luò)地址塊
        cidr_block = "10.1.0.0/21"
      }
      
      resource "alicloud_vswitch" "main" {
        vpc_id = alicloud_vpc.main.id
        # 交換機(jī)地址塊
        cidr_block = "10.1.0.0/24"
        # 可用區(qū)
        zone_id = data.alicloud_zones.default.zones[0].id
      }

   2. 運(yùn)行terraform apply開(kāi)始創(chuàng)建資源。

   3. 運(yùn)行terraform show查看已創(chuàng)建的專(zhuān)有網(wǎng)絡(luò)和交換機(jī)。

2. 創(chuàng)建負(fù)載均衡實(shí)例，并添加監(jiān)聽(tīng)。本示例中創(chuàng)建了一個(gè)預(yù)付費(fèi)的負(fù)載均衡實(shí)例，并添加了一個(gè)tcp監(jiān)聽(tīng)。

   1. 在terraform.tf文件中增加以下內(nèi)容：

      resource "alicloud_slb_load_balancer" "instance" {
        load_balancer_name   = "slb_worder"
        load_balancer_spec   = "slb.s3.small"
        internet_charge_type = "PayByTraffic"
        address_type         = "intranet"
        vswitch_id           = alicloud_vswitch.main.id
      }
      
      resource "alicloud_slb_listener" "listener" {
        load_balancer_id = alicloud_slb_load_balancer.instance.id
        backend_port     = "2111"
        frontend_port    = "21"
        protocol         = "tcp"
        bandwidth        = "5"
      }

   2. 運(yùn)行terraform apply開(kāi)始創(chuàng)建。出現(xiàn)類(lèi)似下面的日志，說(shuō)明創(chuàng)建成功。

      alicloud_slb_load_balancer.instance: Creating...
      alicloud_slb_load_balancer.instance: Still creating... [10s elapsed]
      alicloud_slb_load_balancer.instance: Creation complete after 10s [id=lb-bp13b3e2m9l8wjwh3y8px]
      alicloud_slb_listener.listener: Creating...
      alicloud_slb_listener.listener: Creation complete after 3s [id=lb-bp13b3e2m9l8wjwh3y8px:tcp:21]
      ......
      Apply complete! Resources: 2 added, 0 changed, 0 destroyed.

   3. 運(yùn)行terraform show查看已經(jīng)創(chuàng)建負(fù)載均衡實(shí)例。
