岁月如歌 2019-10-27
在开始之前,这篇文章并不是初级入门的文章,在该文章发布之前已经有两篇文章讲述了FastDFS和SpringBoot相关的知识,请参阅:
《Java高级架构之FastDFS分布式文件集群》:https://blog.51cto.com/xvjunjie/2377669
如果需要在FastDFS中实现HTTPS功能,请参阅:
在下图中,任何一个节点都支持水平横向无限扩展。当在某一个Group中添加新的Storage服务器的时候,新加入该Group的服务器会自动同步所有数据。当新添加Group的时候,只需要修改处于前端的Nginx服务器即可。

在全部主机上执行启动服务并设置为开机自启动

启动所有服务
systemctl daemon-reload systemctl start nginx systemctl enable nginx # 如果是跟踪服务器执行这两行 systemctl restart fdfs_trackerd systemctl enable fdfs_trackerd # 如果是存储服务器执行这两行 systemctl restart fdfs_storaged systemctl enable fdfs_storaged
在任意一台服务器配置/etc/fdfs/client.conf
base_path=/data/fdfs/client tracker_server=192.168.80.21:22122 tracker_server=192.168.80.22:22122 tracker_server=192.168.80.23:22122
在这台服务器进行上传文件测试
可以看到经过多次上传测试,多Group+多Tracker+多Storager生效了。

在SpringBoot中使用FastDFS的时候需要集成fastdfs-spring-boot-starter:
项目主页GitHub地址:https://github.com/bluemiaomiao/fastdfs-spring-boot-starter
克隆项目到本地
git clone https://github.com/bluemiaomiao/fastdfs-spring-boot-starter.git cd fastdfs-spring-boot-starter
使用Maven编译打包并安装到本地
mvn clean install mvn source:jar install mvn javadoc:jar install
在POM文件中添加依赖
<dependency> <groupId>com.bluemiaomiao</groupId> <artifactId>fastdfs-spring-boot-starter</artifactId> <version>1.0-SNAPSHOT</version> </dependency>
在主配置类上添加注解 (
@EnableFastdfsClient
)
@EnableFastdfsClient @SpringBootApplication public class DemoApplication { @Autowired private FastdfsClientService fastdfsClientService; public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } }
添加配置条目(application.properties)
fastdfs.nginx-servers=192.168.80.50:80,192.168.80.51:80 fastdfs.tracker-servers=192.168.80.21:22122,192.168.80.22:22122,192.168.80.23:22122 fastdfs.http-secret-key=2scPwMPctXhbLVOYB0jyuyQzytOofmFCBIYe65n56PPYVWrn # 在本项目中没有使用Token功能 fastdfs.http-anti-steal-token=false fastdfs.http-tracker-http-port=8080 fastdfs.network-timeout=30 fastdfs.connect-timeout=5 fastdfs.connection-pool-max-idle=18 fastdfs.connection-pool-min-idle=2 fastdfs.connection-pool-max-total=18 fastdfs.charset=UTF-8
或者添加配置条目(application.yml)
fastdfs: charset: UTF-8 connect-timeout: 5 http-secret-key: 2scPwMPctXhbLVOYB0jyuyQzytOofmFCBIYe65n56PPYVWrn network-timeout: 30 http-anti-steal-token: false http-tracker-http-port: 8080 connection-pool-max-idle: 20 connection-pool-max-total: 20 connection-pool-min-idle: 2 nginx-servers: 192.168.80.50:80,192.168.80.51:80 tracker-servers: 192.168.80.21:22122,192.168.80.22:22122,192.168.80.23:22122
测试主要代码
