[fastdfs] dockerfile搭建fastdfs分布式集群

具體搭建過程參照官方wiki：

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

按照官方wiki,將配置文件做修改並打包,然后自己寫成Dockerfile

1.環境准備

1.虛擬機三台：

• 10.211.55.21 centos7
• 10.211.55.22 centos7
• 10.211.55.23 centos7

2.用到的包文件，可以選擇下載好，也可以直接通過dockerfile中指定命令git下載；

這里我使用下載好的包文件：tools.tar.gz

[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.創建目錄

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

將包文件tools.tar.gz放於~/fdfs_env下

2.Dockerfile和fdfs配置文件准備

1.Dockerfile編寫

~/fdfs_env下新建Dockerfile文件

FROM centos7:1.0

RUN cp -r /usr/local/src/tools/* .
RUN rm -rf tools
# 安裝 libfastcommon

RUN /usr/bin/unzip ./libfastcommon-master.zip
WORKDIR /usr/local/src/libfastcommon-master
RUN ./make.sh && ./make.sh install

RUN cp /usr/local/src/fastdfs-master/conf/http.conf /etc/fdfs/
RUN cp /usr/local/src/fastdfs-master/conf/mime.types /etc/fdfs/

#安裝fastdfs-nginx-module
WORKDIR /usr/local/src
RUN /usr/bin/unzip ./fastdfs-nginx-module-master.zip
RUN cp /usr/local/src/mod_fastdfs.conf /etc/fdfs
#安裝nginx
RUN /usr/bin/tar -zxvf ./nginx-1.16.1.tar.gz
WORKDIR /usr/local/src/nginx-1.16.1
RUN ./configure --add-module=/usr/local/src/fastdfs-nginx-module-master/src/
RUN make && make install

RUN cp /usr/local/src/nginx.conf /usr/local/nginx/conf
# 啟動文件
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編寫

回到上層路徑，cd ~

創建docker-compose.yml

fastdfs:
  # build: ./fdfs_env
  build: ./fdfs_env_single
  restart: always  # 開機自啟
  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

# 主要修改的內容如下
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

# 主要修改的內容如下
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

# 主要修改的內容如下
port=23000  # storage服務端口（默認23000,一般不修改）
base_path=/home/fastdfs/storage  # 數據和日志文件存儲根目錄
store_path0=/home/fastdfs/storage  # 第一個存儲目錄
 
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訪問文件的端口(默認8888,看情況修改,和nginx中保持一致)

• tracker.conf

# 主要修改的內容如下
port=22122  # tracker服務器端口（默認22122,一般不修改）
base_path=/home/fastdfs/tracker  # 存儲日志和數據的根目錄

• start.sh腳本

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

3.測試上傳

1.任意節點上傳文件

選擇一個節點，進入容器

docker exec -it fastdfs bash

上傳文件

fdfs_upload_file /etc/fdfs/client.conf 上傳文件路徑

成功，則返回

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

2.通過nginx訪問該文件

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

可以下載，說明成功了。
