dfs__1">一、 Fastdfs 介绍

FastDFS 是一款高性能的分布式文件系统，特别适合用于存储和管理大量的文件

二、部署 信息

• 使用 docker 部署 Fastdfs 集群

角色	服务器 IP	服务器系统	服务器配置	docker /docker-compose版本
tracker/storage	10.10.11.35	麒麟 V10	127G + 96C	18.09.0/v2.25.0
tracker/storage	10.10.11.56	麒麟 V10	254G + 64C	20.10.17/v2.5.0

• 默认 tracker 端口为 22122， storage 端口为 23000，文件访问端口为 8080
• 此文档使用镜像在 dockerhub 上有，x86 与 arm 双架构均存在，可以直接 pull

三、步骤

tracker/storage 机器的 compose 内容

• 由于此容器内部启动使用 sed，所以根据内部命令来启动，编辑环境变量以及域名解析，多个 tracker 使用 \n 换行符实现

version: '3.8'

• 访问地址 http://10.10.11.35:8080/group111/M00/00/00/CgoLOGdf6m6AeFMrAAAABqkTGlI497_big.txt

• fastdfs 集群直接的 storage 会自动同步数据，更换 ip 再次访问，也可以成功访问

测试集群扩容与缩减

• 扩容：目前有两种方法，扩容容量需要增加硬盘，挂载分区，扩容节点需要增加新的 group，修改新节点的配置后就可以加入集群，原有集群有数据后是无法直接增加节点的，除了上面增加 group 的方法就只能清除数据重新部署节点，所以推荐在部署集群之前最好先确认架构，防止后续因为架构调整带来的不必要的麻烦
• 缩减：由于集群会自动同步数据，要缩减直接直接关闭storage、修改nginx代理即可

nginx 负载配置（示例配置）

upstream storage {server 10.10.11.56:23000;server 10.10.11.35:23000;
}upstream storage_file {server 10.10.11.56:8080;server 10.10.11.35:8080;
}
upstream tracker {server 10.10.11.56:22122;server 10.10.11.35:22122;
}server {listen 23001 ;server_name _;location / {proxy_set_header Host $http_host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-Proto $scheme;proxy_set_header X-Forwarded-Host $http_host;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass http://storage;}
}server {listen 8889;server_name _;location / {proxy_set_header Host $http_host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-Proto $scheme;proxy_set_header X-Forwarded-Host $http_host;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass http://storage_file;}
}server {listen 22123;server_name _;location / {proxy_set_header Host $http_host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-Proto $scheme;proxy_set_header X-Forwarded-Host $http_host;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass http://tracker;}
}

注意事项

• fastdfs 默认保留的磁盘空间为 10%，当至少有一个节点的磁盘存储小于或等于 10%时，文件无法写入，可以更改保留空间，修改 tracker 容器中 /etc/fdfs/tracker.conf，进入容器使用 echo “reserved_storage_space = 1%” >> /etc/fdfs/tracker.conf 追加，所有的 tracker 都需要更改，然后单独重启 tracker，清空原有数据，即 data 下的所有内容，重启 storage 即可
• 如果遇到一直不同步的清空，则删除 等待节点，重新启动，或删除全部 数据，重新创建容器
