让我们学习如何将 Java Spring Boot Web 服务器部署到 Amazon EC2。每月只需 3 美元。
使用 Azure，您可能不知道要花费多少钱。
Spring Boot 项目示例
在本教程中，我们将重点介绍如何将 Java Spring Boot 服务器部署到 Amazon EC2，因此我们不会学习如何从头开始构建 Spring Boot Web 服务。
启动 Amazon Linux EC2 实例
首先，编写下面的main.tf文件
provider "aws" {region = "ap-southeast-2"
}resource "aws_instance" "example_server" {ami = "ami-0f6a1a6507c55c9a8"instance_type = "t2.micro"key_name = "rockaws"tags = {Name = "RockSpringBootExample"}
}运行terraform apply 来创建EC2。
ninjamac@ip-192-168-1-2 target % terraform apply Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:+ createTerraform will perform the following actions:# aws_instance.example_server will be created
Plan: 1 to add, 0 to change, 0 to destroy.Do you want to perform these actions?Terraform will perform the actions described above.Only 'yes' will be accepted to approve.Enter a value: yesaws_instance.example_server: Creating...
aws_instance.example_server: Still creating... [10s elapsed]
aws_instance.example_server: Creation complete after 16s [id=i-0d3b6e22f089bebf2]通过 SSH 连接到 EC2 实例
ninjamac@ip-192-168-1-2 key % ssh -i rockaws.pem ec2-user@13.211.xx.xxThe authenticity of host '13.211.xx.xx (13.211.xx.xx)' can't be established.
ED25519 key fingerprint is SHA256:Q45g4PVqKnhtTnw9KQnWXnF5LoeOAFQ7qH2khVmw+Hg.
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

在 EC2 安全组中为 Spring Boot 启用 8080 端口
前往连接到您的 EC2 实例的安全组，并添加 8080 端口范围：
使用 IP 测试在 EC2 上运行的 Spring Boot 服务器
使用curl测试 actuator的健康状态
ninjamac@ip-192-168-1-2 target % curl 13.211.239.xx:8080/actuator/health
{"status":"UP"}%如何为生产环境设置 Spring Boot
- 使用 Caddy 设置自定义域名和 SSL
- 将您的域名指向 EC2 IP
- 安装并设置 Caddy 作为反向代理
- 设置 CDN（例如 CloudFront 或 Cloudflare）用于缓存
保持 Java 服务器在后台运行
我们希望在系统重启和应用程序崩溃时自动启动应用程序，为此可以使用 systemd。
创建 systemd 服务文件
使用 vim 在 /etc/systemd/system/java-server.service 中创建一个服务文件：
sudo vim /etc/systemd/system/java-server.service
[Unit]
Description=Spring Boot Server[Service]
ExecStart=java -jar /home/ec2-user/hello-0.0.1-SNAPSHOT.jar
Restart=on-failure
RestartSec=1s[Install]
WantedBy=multi-user.target使用 systemctl 启用 java-server 服务
现在您需要重新加载 systemd 并启用 java 服务器：
sudo systemctl daemon-reload
sudo systemctl enable java-server
启动 java-server 服务
sudo systemctl start java-server
使用 systemctl 检查状态
sudo systemctl status java-server
您将看到类似以下内容：
[ec2-user@ip-172-31-14-36 ~]$ sudo systemctl daemon-reload
[ec2-user@ip-172-31-14-36 ~]$ sudo systemctl enable java-server
Created symlink /etc/systemd/system/multi-user.target.wants/java-server.service → /etc/systemd/system/java-server.service.
[ec2-user@ip-172-31-14-36 ~]$ sudo systemctl start java-server
[ec2-user@ip-172-31-14-36 ~]$ sudo systemctl status java-server
