docker安装部署、fastDFS文件服务器搭建与springboot项目接口

一、docker安装部署

1、更新yum包：sudo yum update
2、安装需要的软件包，yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的
    sudo yum install -y yum-utils device-mapper-persistent-data lvm2
3、设置yum源：sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
4、可以查看所有仓库中所有docker版本，并选择特定版本安装：yum list docker-ce --showduplicates | sort -r
5、安装docker：yum install docker-ce-18.03.0.ce
6、启动、设置开启开机启动
        sudo systemctl start docker
        sudo systemctl enable docker
7、验证安装是否成功(有client和service两部分表示docker安装启动都成功了)：docker version
8、查看docker启动状态：systemctl status docker（启动成功active(running)）　

二、fastDFS文件服务器搭建

fastdfs 安装
1、拉取镜像: docker pull morunchang/fastdfs
2、启动tracker: docker run -d --name tracker --net=host morunchang/fastdfs sh tracker.sh
3、启动storage （172.21.91.218 ip 自行替换为docker 所在服务器的ip )( 此镜像不支持-p 参数）
docker run -d --name storage --net=host -e TRACKER_IP=172.21.91.218:22122 -e GROUP_NAME=group1 morunchang/fastdfs sh storage.sh

可选配置
storage 内部nginx 端口修改 以22999为例
1.进入容器内部: docker exec -it storage /bin/bash
2.修改nginx配置文件: vim /etc/nginx/conf/nginx.conf
修改 http.server.listen 8080 为 22999
sed -i 's/8080/22999/g' /etc/nginx/conf/nginx.conf
3.退出容器
exit
4.重启storage
docker restart storage

//浏览器访问路径 http://172.21.91.218:22999/group1/M00/00/00/rBVb2lwPNYeAZtTLAAAXxD4H4Z8674.txt

相关端口开放
firewall-cmd --zone=public --add-port=22122/tcp --permanent
firewall-cmd --zone=public --add-port=23000/tcp --permanent
firewall-cmd --zone=public --add-port=8080/tcp --permanent
firewall-cmd --reload

三、java springboot项目相关接口

1、引入依赖
           <dependency>
                <groupId>com.github.tobato</groupId>
                <artifactId>fastdfs-client</artifactId>
                <version>1.27.2</version>
            </dependency>
2、controller接口
package com.lihe.mes.identity.controller;

 四、yml文件配置

#文件服务器
fdfs:
  so-timeout: 1501
  connect-timeout: 601
  thumb-image: # 缩略图
     200
    height: 200
  tracker-list: # tracker地址
    - 文件服务器ip:22122
