[fastdfs] dockerfile搭建fastdfs分布式集群

具体搭建过程参照官方wiki：

https://github.com/happyfish100/fastdfs/wiki

按照官方wiki,将配置文件做修改并打包,然后自己写成Dockerfile

1.环境准备

1.虚拟机三台：

10.211.55.21 centos7
10.211.55.22 centos7
10.211.55.23 centos7

2.用到的包文件，可以选择下载好，也可以直接通过dockerfile中指定命令git下载；

这里我使用下载好的包文件：tools.tar.gz
下载地址：https://download.csdn.net/download/Ryxiong728/12396474

[ryxiong@centos7 fdfs_env_single]$ tree tools
tools
├── client.conf
├── fastdfs-master.zip
├── fastdfs-nginx-module-master.zip
├── libfastcommon-master.zip
├── mod_fastdfs.conf
├── nginx-1.16.1.tar.gz
├── nginx.conf
├── start.sh
├── storage.conf
└── tracker.conf

3.创建目录

mkdir -p ~/fasdfs/tracker  # tracker映射路径
mkdir -p ~/fasdfs/storage  # storage映射路径
mkdir -p ~/fdfs_env  # dockerfile和包文件路径

将包文件tools.tar.gz放于~/fdfs_env下

2.Dockerfile和fdfs配置文件准备

1.Dockerfile编写

~/fdfs_env下新建Dockerfile文件

FROM centos7:1.0

RUN rm -rf tools
# 安装 libfastcommon

RUN /usr/bin/unzip ./libfastcommon-master.zip

RUN ./make.sh && ./make.sh install

WORKDIR /usr/local/src
RUN /usr/bin/unzip ./fastdfs-nginx-module-master.zip
RUN cp /usr/local/src/mod_fastdfs.conf /etc/fdfs
#安装nginx
RUN /usr/bin/tar -zxvf ./nginx-1.16.1.tar.gz

RUN cp /usr/local/src/start.sh /usr/local/bin/
RUN ls /usr/local/bin
RUN chmod +x /usr/local/bin/start.sh
ENTRYPOINT ["/usr/local/bin/start.sh"]

WORKDIR /
EXPOSE 8888

2.docker-compose.yml编写

回到上层路径，cd ~

创建docker-compose.yml

fastdfs:
  # build: ./fdfs_env
  build: ./fdfs_env_single
  restart: always  # 开机自启
  container_name: fastdfs
  volumes:
    - ./fastdfs/tracker:/home/fastdfs/tracker
    - ./fastdfs/storage:/home/fastdfs/storage
    - /etc/localtime:/etc/localtime
  environment:
    - LANG=C.UTF-8
  network_mode: host

3.tools包中的配置文件修改

client.conf

# 主要修改的内容如下
base_path=/home/fastdfs/tracker
tracker_server=10.211.55.21:22122
tracker_server=10.211.55.22:22122
tracker_server=10.211.55.23:22122

mod_fastdfs.conf

# 主要修改的内容如下
tracker_server=10.211.55.21:22122
tracker_server=10.211.55.22:22122
tracker_server=10.211.55.23:22122
url_have_group_name=true
store_path0=/home/fastdfs/storage

storage.conf

# 主要修改的内容如下
port=23000  # storage服务端口（默认23000,一般不修改）
base_path=/home/fastdfs/storage  # 数据和日志文件存储根目录
store_path0=/home/fastdfs/storage  # 第一个存储目录
 
tracker_server=10.200.18.200:22122
tracker_server=10.200.18.201:22122
tracker_server=10.200.18.202:22122
 
http.server_port=8888  # http访问文件的端口(默认8888,看情况修改,和nginx中保持一致)

tracker.conf

# 主要修改的内容如下
port=22122  # tracker服务器端口（默认22122,一般不修改）
base_path=/home/fastdfs/tracker  # 存储日志和数据的根目录

start.sh脚本

#!/bin/sh
/etc/init.d/fdfs_trackerd start
/etc/init.d/fdfs_storaged start
/usr/local/nginx/sbin/nginx -g 'daemon off;'

3.测试上传

1.任意节点上传文件

选择一个节点，进入容器

docker exec -it fastdfs bash

上传文件

fdfs_upload_file /etc/fdfs/client.conf 上传文件路径

成功，则返回

root@centos7 /]# fdfs_upload_file /etc/fdfs/client.conf anaconda-post.log 
group1/M00/00/00/rBJ76F6zgdmASUvqAAAvW43Lfro568.log

2.通过nginx访问该文件

http://10.211.55.21:8888/group1/M00/00/00/rBJ76F6zgdmASUvqAAAvW43Lfro568.log
http://10.211.55.22:8888/group1/M00/00/00/rBJ76F6zgdmASUvqAAAvW43Lfro568.log
http://10.211.55.23:8888/group1/M00/00/00/rBJ76F6zgdmASUvqAAAvW43Lfro568.log

可以下载，说明成功了。
