阿里云服务器 liunx系统docker安装部署fastdfs，和springboot整合fastdfs

阿里云服务器 liunx系统docker安装部署fastdfs，和springboot整合fastdfs,我是以CentOS7系统为例

1. 如果你没有安装docker，执行以下命令安装

yum install docker

2. 启动、设置开启开机启动docker

       sudo systemctl start docker
　　　　sudo systemctl enable docker

3. 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

4. 镜像拉取fastdfs，可能拉取比较慢，请耐心等待

docker pull delron/fastdfs

5. 创建tracker容器

docker run -d --network=host --name tracker -v /var/fdfs/tracker:/var/fdfs delron/fastdfs tracker

执行如下命令查看tracker是否运行起来

docker container ls

如果想停止tracker服务，可以执行如下命令

docker container stop tracker

停止后，重新运行tracker，可以执行如下命令

 docker container start tracker

6. 创建storage容器

docker run -d --network=host --name storage -e TRACKER_SERVER=服务器公网ip:22122 -v /var/fdfs/storage:/var/fdfs -e GROUP_NAME=group1 delron/fastdfs storage

执行如下命令查看storage是否运行起来

docker container ls

如果想停止storage服务，可以执行如下命令

docker container stop storage

停止后，重新运行storage，可以执行如下命令

docker container start storage

7. 创建springboot项目，在这里我用的是springboot1.5的版本，因为使用springboot2.x的版本会报以下错误，如果找解决方案，会第一时间和大家的分享

6. 当然，你同样需要配置阿里云服务器安全组
