拉取镜像
docker pull morunchang/fastdfs查看镜像
[root@iZh3cshm0xz7wjZ ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
docker.io/morunchang/fastdfs latest a729ac95698a 18 months ago 460.1 MB运行tracker
docker run -d --name tracker --net=host morunchang/fastdfs sh tracker.sh运行storage
docker run -d --name storage --net=host -e TRACKER_IP=<your tracker server address>:22122 -e GROUP_NAME=<group name> morunchang/fastdfs sh storage.sh1.使用的网络模式是–net=host, 替换为你机器的Ip即可
2.group name 是组名，即storage的组，下面默认用group1
3.如果想要增加新的storage服务器，再次运行该命令，注意更换 新组名
4.docker ps 查看容器信息

*/修改nginx的配置，不拦截上传内容
进入storage的容器内部，修改nginx.conf
进入容器内部
docker exec -it storage /bin/bash
// storage 是 docker ps 中的NAMES
// exit 退出root@iZh3cshm0xz7wjZ:/# cd data
root@iZh3cshm0xz7wjZ:/data# ls
fast_data fastdfs fastdfs-nginx-module libfastcommon nginx nginx-1.9.11.tar.gz修改nginx配置文件
root@iZh3cshm0xz7wjZ:/# vi /data/nginx/conf/nginx.conf添加修改内容

storage到这里docker已经安装完成。
---------------------------------------华丽的分割线-----------------------------------------------
下面是与springMVC项目集成
上传fastdfs-client-java至nexus私有库上，
配置项目maven的pom文件
<dependency>
<groupId>org.csource</groupId>
<artifactId>fastdfs-client-java</artifactId>
<version>1.27</version>
</dependency>
resources下新建fast_client.conf文件
并新增以下内容
connect_timeout = 60
#网络超时时间
network_timeout = 60
#字符集
charset = UTF-8
#跟踪服务器的端口
http.tracker_http_port = 8080
http.anti_steal_token = no
http.secret_key = 123456
#跟踪服务器地址 。跟踪服务器主要是起到负载均衡的作用
tracker_server = ip:22122

编写测试类

String code = (String) retMap.get("code");
String group = (String) retMap.get("group");
String msg = (String) retMap.get("msg");
if ("0000".equals(code)){
logger.info("文件上传成功");
//TODO:将上传文件的路径保存到mysql数据库
}else {
logger.info("文件上传失败");
}
}
return "/success";
}
返回msg为文件存储路径，测试后拼接ip端口，浏览器访问，可以访问则集成成功。
