FastDFS安装配置参考:https://www.cnblogs.com/minseo/p/10210428.html
环境介绍
需要同步的tracker:192.168.56.11 需要同步的storage:192.168.56.12 新的tracker:192.168.56.21 新的storage:192.168.56.22
停止storage进程
systemctl stop fdfs_storaged
修改storage配置/etc/fdfs/storage.conf

启动storage
systemctl start fdfs_storaged
此时数据会同步,查看同步过程 提示ACTIVE则代表同步完成
fdfs_monitor /etc/fdfs/storage.conf
同步之前在旧的上面上传了一个文件 目录为/opt/fdfsdata/storage/data/00/00
同步完成后在新的storage服务器上面相同目录有相同文件

同步完成后修改配置文件/etc/fdfs/storage.conf仅需要修改一行指向新的tracker服务器
tracker_server=192.168.56.21:22122
进入storage文件目录修改
cd /opt/fdfsdata/storage/data vim .data_init_flag sync_src_server= #留空即可
重启storage
systemctl restart fdfs_storaged
