fastdfs分布式

docker 安装分布式fastdfs

安装之前可以先进官网 dockerhub.com

docker pull season/fastdfs（安装）

（打包镜像）
docker run -ti -d --name trakcer -v ~/tracker_data:/fastdfs/tracker/data --net=host season/fastdfs tracker

• 注意：需要关闭防火墙

systemctl stop firewalld

find / -name selinux

进去之后找到第一个vi 编辑 /etc/sysconfig/selinux

进去后将selinux的值改成disabled

改了之后需要重启， reboot

之后 运行生成storage镜像 注意**：IP地址写自己的地址**
docker run -ti -d --name storage -v ~/storage_data:/fastdfs/storage/data -v ~/store_path:/fastdfs/store_path --net=host -e TRACKER_SERVER:192.168.241.130:22122 season/fastdfs storage

进入tracker docker exec -it tracker bash

测试是否成功

fdfs_monitor storage.conf

这样说明没有注册上，需要手工去配storage

退出tracker 进入storage

[root@localhost ~]# docker exec -it storage bash
root@localhost:/# ls
FastDFS_v4.08  boot  entrypoint.sh  fastdfs    home  lib32  libevent-2.0.14  mnt  proc  run   selinux  sys  usr
bin            dev   etc            fdfs_conf  lib   lib64  media            opt  root  sbin  srv      tmp  var
root@localhost:/# cd  fdfs_conf
root@localhost:/fdfs_conf# ls
anti-steal.jpg  client.conf  http.conf  mime.types  storage.conf  storage_ids.conf  tracker.conf
root@localhost:/fdfs_conf# more storage.conf

会发现这里的IP地址还是没有更换
需要将这个拷贝出去修改了之后再拷贝回来

完成之后进去storage输入命令
fdfs_monitor storage.conf

成功

上传文件

root@localhost:/fdfs_conf# fdfs_upload_file storage.conf /a.txt

group1/M00/00/00/wKjxglwGdkWAf5xfAAAABncc3SA266.txt

直接进linux 的stora path cd /date/00/00
more 打印文件

用java 上传
