CentOS7.5下搭建高可用的FastDFS分布式文件系统

FastDFS是一个开源的轻量级分布式文件系统,由跟踪服务器(tracker server)、存储服务器(storage server)和客户端(client)三个部分组成,主要解决了海量数据存储问题,特别适合以中小文件(建议范围:4KB < file_size <500MB)为载体的在线服务。

成都一家集口碑和实力的网站建设服务商,拥有专业的企业建站团队和靠谱的建站技术,十多年企业及个人网站建设经验 ,为成都上1000+客户提供网页设计制作,网站开发,企业网站制作建设等服务,包括成都营销型网站建设,品牌网站建设,同时也为不同行业的客户提供网站设计、成都网站建设的服务,包括成都电商型网站制作建设,装修行业网站制作建设,传统机械行业网站建设,传统农业行业网站制作建设。在成都做网站,选网站制作建设服务商就选成都创新互联

(1)每次上传文件后都会返回一个地址,用户需要自己保存此地址。

(2)为了支持大容量,存储节点(服务器)采用了分卷(或分组)的组织方式。存储系统由一个或多个卷组成,卷与卷之间的文件是相互独立的,所有卷的文件容量累加就是整个存储系统中的文件容量。一个卷可以由一台或多台存储服务器组成,一个卷下的存储服务器中的文件都是相同的,卷中的多台存储服务器起到了冗余备份和负载均衡的作用。

 

配置环境:

CentOS 7.5 x 64

tracker server: 192.168.5.71(tracker暂时一台,后续再添加一台做nginx+keepalived高可用)

storage server: 192.168.5.72 192.168.5.73(group1)

storage server: 192.168.5.74 192.168.5.75(group2)

 

#hosts文件配置

cat >> /etc/hosts << EOF

下载刚才上传的文件:
# fdfs_download_file /etc/fdfs/client.conf group1/M00/00/00/wKgFSFvBpdSAB33ZAAI8IU3BQ48068.jpg

查看文件属性:
# fdfs_file_info /etc/fdfs/client.conf group1/M00/00/00/wKgFSFvBpdSAB33ZAAI8IU3BQ48068.jpg

删除上传的文件:
# fdfs_delete_file /etc/fdfs/client.conf group1/M00/00/00/wKgFSFvBpdSAB33ZAAI8IU3BQ48068.jpg
# fdfs_delete_file /etc/fdfs/client.conf group1/M00/00/00/wKgFSFvBtTuAGz2VAAAJHTkxfCU312.txt

监控fastdfs的状态:
# fdfs_monitor /etc/fdfs/client.conf
