FastDFS的HA架构多Group多Storage多Tracker结合SpringBoot
FastDFS前奏

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。要实现主备自动切换还可以加入KeepAlived中间件。
- FastDFS服务器通过HTTP提供服务,但是HTTP的性能太弱,所以在V4.05之后的版本中删除了内置的HTTP服务。
- FastDFS的Group之间的Storage需要复制数据,如果请求的数据正在复制,由于不是源服务器,那么fastdfs-nginx-module将进行重定向源服务器。
- fastdfs-nginx-module支持配置多个组,一个服务器可以配置多个Group不同的Storage。同一个Group的Storage必须端口相同。
- Nginx会为FastDFS提供负载均衡和数据缓存的功能。
- FastDFS集群的总容量等于全部Group容量之和。一个Group的容量等于最小的Storage服务器容量。
- 组一般用于隔离不同的数据。

(3)配置Tracker服务器集群
# 配置tracker的IP地址或者主机域名,前提要进行配置静态hosts解析或者配置DNS
bind_addr=192.168.80.21
# tracker的数据和日志存储目录
base_path=/data/fdfs/tracker
(4)配置Storage服务器集群
# 配置该Storage服务属于哪一个Group
group_name=group1
# 配置绑定的IP地址或者主机域名
bind_addr=192.168.80.12
# 配置日志存储目录
base_path=/data/fdfs/storage
# 配置数据存储目录的个数

# 配置数据存储目录

tracker_server=192.168.80.22:22122
tracker_server=192.168.80.23:22122
在全部主机上执行启动服务并设置为开机自启动
(5)在NGINX节点上配置NGINX进行负载均衡
NGINX配置文件
user nginx;
worker_processes 8;
error_log logs/error.log;
pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
sendfile on;
keepalive_timeout 65;
gzip on;
# Group1的Storage节点
upstream g1_pool {
server 192.168.80.11 weight=1;
server 192.168.80.12 weight=1;
server 192.168.80.13 weight=1;
}
# Group2的Storage节点
upstream g2_pool {
server 192.168.80.14 weight=1;
server 192.168.80.15 weight=1;
server 192.168.80.16 weight=1;
}
# Group3的Storage节点
upstream g3_pool {
server 192.168.80.17 weight=1;
server 192.168.80.18 weight=1;
server 192.168.80.19 weight=1;
}
server {
listen 80;
server_name localhost;
access_log logs/host.access.log main;
location ~/group1 {
proxy_pass http://g1_pool;
}
location ~/group2 {
proxy_pass http://g2_pool;
}
location ~/group3 {
proxy_pass http://g3_pool;
}
}
}
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
(6)使用FastDFS自带的Client上传图片进行测试
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。

(7)集成到SpringBoot工程进行测试
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
- 项目主页码云地址:https://gitee.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
com.bluemiaomiao
fastdfs-spring-boot-starter
1.0-SNAPSHOT
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
