操作步驟

1. 創(chuàng)建一個(gè)負(fù)載均衡實(shí)例。

   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。

      說(shuō)明

      需要為每個(gè)Terraform項(xiàng)目創(chuàng)建一個(gè)獨(dú)立的執(zhí)行目錄。在初始化配置之前至少需要有1個(gè).tf文件。

      resource "alicloud_slb_load_balancer" "instance" {
        load_balancer_name   = "slb_worder"
        load_balancer_spec   = "slb.s3.small"
        internet_charge_type = "PayByTraffic"
        address_type         = "internet"
      }

   2. 運(yùn)行terraform apply開(kāi)始創(chuàng)建。出現(xiàn)類似下面的日志，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 14s [id=lb-gw89kh14ra0htarr1ub8n]
      ......
      Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

   3. 運(yùn)行terraform show查看已創(chuàng)建的負(fù)載均衡實(shí)例。

2. 添加監(jiān)聽(tīng)。以下示例添加了TCP、UDP和HTTP三種協(xié)議的監(jiān)聽(tīng)。

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

      說(shuō)明

      在該目錄下所有*.tf 文件都會(huì)被terraform自動(dòng)加載。因此，用戶可以按照實(shí)際用途將配置信息寫(xiě)入不同的文件中。

      resource "alicloud_slb_listener" "tcp" {
        load_balancer_id          = alicloud_slb_load_balancer.instance.id
        backend_port              = "22"
        frontend_port             = "22"
        protocol                  = "tcp"
        bandwidth                 = "10"
        health_check_type         = "tcp"
        persistence_timeout       = 3600
        healthy_threshold         = 8
        unhealthy_threshold       = 8
        health_check_timeout      = 8
        health_check_interval     = 5
        health_check_http_code    = "http_2xx"
        health_check_connect_port = 20
        health_check_uri          = "/console"
        established_timeout       = 600
      }
      
      resource "alicloud_slb_listener" "udp" {
        load_balancer_id          = alicloud_slb_load_balancer.instance.id
        backend_port              = 2001
        frontend_port             = 2001
        protocol                  = "udp"
        bandwidth                 = 10
        persistence_timeout       = 3600
        healthy_threshold         = 8
        unhealthy_threshold       = 8
        health_check_timeout      = 8
        health_check_interval     = 4
        health_check_connect_port = 20
      }
      
      resource "alicloud_slb_listener" "http" {
        load_balancer_id          = alicloud_slb_load_balancer.instance.id
        backend_port              = 80
        frontend_port             = 80
        protocol                  = "http"
        sticky_session            = "on"
        sticky_session_type       = "insert"
        cookie                    = "testslblistenercookie"
        cookie_timeout            = 86400
        health_check              = "on"
        health_check_uri          = "/cons"
        health_check_connect_port = 20
        healthy_threshold         = 8
        unhealthy_threshold       = 8
        health_check_timeout      = 8
        health_check_interval     = 5
        health_check_http_code    = "http_2xx,http_3xx"
        bandwidth                 = 10
        request_timeout           = 80
        idle_timeout              = 30
      }

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

      alicloud_slb_listener.udp: Creating...
      alicloud_slb_listener.http: Creating...
      alicloud_slb_listener.tcp: Creating...
      alicloud_slb_listener.http: Creation complete after 5s [id=lb-gw89kh14ra0htarr1ub8n:http:80]
      ......
      Apply complete! Resources: 3 added, 0 changed, 0 destroyed.

   3. 運(yùn)行terraform show查看已創(chuàng)建的監(jiān)聽(tīng)。
