1 Swarm部署

1.1 注意点

1. fastdfs.yml 里的 TRACKER_SERVER 是宿主主机的IP地址，部署时需要先手工设置好。
2. 部署好 nginx 后，需要手工将 external/fastdfs.conf 文件拷贝到 docker volumn 的 `chaipp_nginx-conf/_data/conf.d/`目录里，并重启 nginx 服务（后续有时间自己做个镜像就不要这么麻烦了）。
3.  重启Nginx后，可以访问了：http://192.168.1.220:58080/data/00/00/wKgB3F022LyAMBqgABtktRyVd54063.png
