Docker 搭建FastDFS文件系统

1、检索和拉取fastDFS镜像

# 检索fastdfs
docker search fastdfs

# 拉取fastdfs
docker pull delron/fastdfs

2、使用docker镜像构建tracker容器

跟踪服务器,起到调度的作用

# 创建tracker 挂载文件目录
mkdir -p /usr/local/fdfs/tracker
# 创建fastdfs 跟踪服务器tracker
docker run -d --network=host --name tracker -v 

[root@localhost ~]# mkdir -p /usr/local/fdfs/tracker
[root@localhost ~]# docker run -d --network=host --name tracker -v /usr/local/fdfs/tracker:/var/fdfs delron/fastdfs tracker

3、使用docker镜像构建storage容器

存储服务器,提供容量和备份服务

TRACKER_SERVER=本机的ip地址:22122 本机ip地址不要使用127.0.0.1

# 创建storage 挂载目录
mkdir -p /usr/local/fdfs/storage

# 创建fastdfs 存储服务器storage
docker run -d --network=host --name storage -e TRACKER_SERVER=192.168.43.10:22122 -v /usr/local/fdfs/storage:/var/fdfs -e GROUP_NAME=group1 delron/fastdfs storage

[root@localhost ~]# mkdir -p /usr/local/fdfs/storage
[root@localhost ~]# docker run -d --network=host --name storage -e TRACKER_SERVER=192.168.43.10:22122 -v /usr/local/fdfs/storage:/var/fdfs -e GROUP_NAME=group1 delron/fastdfs storage
  • 说明1
    x.x.x.x这里要说明一下:这个地址必须使用服务器的的外网地址,否则上传的时候连不上服务器。
  • 说明2
    group1这个不要随便修改,因为默认的nginx的配置中使用的是0到9的数字,如果想修改这个名字,得进入到storage容器中修改nginx的配置文件

此时两个服务都以启动,进行fastdfs服务的相关配置。

4、storage容器配置

4.1 storage 配置文件

进入storage容器,到storage的配置文件中配置http访问的端口,配置文件在/etc/fdfs目录下的storage.conf。

#进入storage 容器后台服务
[root@localhost ~]# docker exec -it storage /bin/bash
# 切换至storage.cnf 文件所在目录/etc/fdfs
[root@localhost nginx-1.12.2]# cd /etc/fdfs
[root@localhost fdfs]# ls -a

 默认端口是8888,可以进行修改也可以不进行修改(建议不进行修改)。

4.2 nginx 配置

进入storage容器配置nginx,在/usr/local/nginx目录下,修改nginx.conf文件

Docker 搭建FastDFS文件系统_第2张图片

默认配置如下:

Docker 搭建FastDFS文件系统_第3张图片 可以修改为如下

# 路径地址
location /group1/M00 {

        alias  /var/fdfs;  #storage 实现存储文件目录

    }

 也可以不做任何修改。(建议不做修改)

5、Tracker容器配置

进入到tracker服务器,配置一下tracker_server的服务器地址。

# 进入tracker 服务配置
docker exec -it tracker /bin/bash
# 编辑storage 服务地址
vi /etc/fdfs/client.conf
[root@localhost ~]# docker exec -it tracker /bin/bash
[root@localhost nginx-1.12.2]# cat /etc/fdfs/client.conf
# connect timeout in seconds
# default value is 30s
connect_timeout=30

# network timeout in seconds
# default value is 30s
network_timeout=60

# the base path to store log files
base_path=/var/fdfs

# tracker_server can ocur more than once, and tracker_server format is
#  "host:port", host can be hostname or ip address
tracker_server=192.168.0.197:22122

将配置 tracker_server=x.x.x.x:22122
到这其实fastDFS就配好了

这里的x.x.x.x也建议设置为服务器的内网ip

6、文件上传测试

进入storage容器,进入/var/fdfs目录

# 进入storage 容器后台服务
docker exec -it storage bash
# 切换至storage 上传文件实际存储目录地址
cd /var/fdfs
# 在当前目录新建a.txt 文件,并且写入hello, world 内容
echo hello,world>a.txt
# 执行a.txt 文本上传
/usr/bin/fdfs_upload_file /etc/fdfs/client.conf a.txt
[root@localhost ~]# docker exec -it storage bash
[root@localhost nginx-1.12.2]# cd /var/fdfs
[root@localhost fdfs]# echo hello,world>a.txt
[root@localhost fdfs]# /usr/bin/fdfs_upload_file /etc/fdfs/client.conf a.txt
group1/M00/00/00/wKgrCmKuo9GAX5N6AAAADLMSuiI034.txt

浏览器访问 http://ip:8888group1/M00/00/00/wKgrCmKuo9GAX5N6AAAADLMSuiI034.txt
端口根据你在starage里面设置的要保持一致,访问之前关闭防火墙 或者自己单独开放端口命令如下:

 7、开放端口(我个人是关闭CentOS 宿主主机的防火墙)

firewall-cmd --zone=public --permanent --add-port=8888/tcp

firewall-cmd --zone=public --permanent --add-port=22122/tcp

firewall-cmd --zone=public --permanent --add-port=23000/tcp

# 重启防火墙
systemctl restart firewalld

8、开机启动容器(一般是运维执行指令,对于普通开发建议使用)

docker update --restart=always tracker

docker update --restart=always storage
