12.3 fastdfs

介绍

FastDFS：开源的高性能分布式文件系统；主要功能包括：文件存储，文件同步和文件访问，以及高容量和负载平衡

FastDFS：角色：跟踪服务器(Tracker Server)、存储服务器(Storage Server)和客户端(Client)

Tracker Server: 跟踪服务器，主要做调度工作，起到均衡的作用；负责管理所有的storage server和group，每个storage在启动后会连接 Tracker，告知自己所属 group 等信息，并保持周期性心跳。多个Tracker之间是对等关系，不存在单点故障
Storage Server: 存储服务器，主要提供容量和备份服务；以 group 为单位，每个 group 内可以有多台 storage server（高可用），组内的storage server上的数据互为备份
Client:客户端，上传下载数据的服务器

fastdfs的安装

6台主机同时进行

下载安装包

安装相关依赖

安装 libfastcommon

安装 FastDFS

tracker安装

在两台tracker上执行

修改tracker配置文件

修改的内容为：

创建工作目录

启动追踪器

开放防火墙端口

storage安装

修改配置文件

修改的文件内容为：

创建目录

启动 storage：

查看集群状态：

在任意一台storage主机即可

开放防火墙端口

客户端测试

tracker台中可以随意找一台做客户端测试下:

修改文件的内容为：

上传一张图片到服务器上

配置FastDFS集群支持http

支持http请求，安装nginx（4个storage节点安装nginx,首先安装fastdfs-nginx-module,fastdfs与nginx集成模块）

修改config编译文件

编译安装

修改mod_fastdfs.conf配置文件

注意:group1:192.168.165.38,39和group2:192.168.165.40,41

复制FastDFS(fastdfs-5.11)里的2个文件到/etc/fdfs/目录下

创建一个软链接，在/fastdfs/storage 文件存储目录下创建软链接，将其链接到实际存放数据的目录

修改nginx配置文件为：

启动nginx

上传图片，然后访问测试

tracker server 上安装 nginx缓存

创建缓存目录

修改nginx配置文件：

启动nginx

上传图片，访问测试

keepalived安装

修改配置文件

准备：另一台的state改为BACKUP，priority改为小于100的值

配置健康检查脚本：

赋予执行权限：

添加防火墙规则

启动服务

用vip访问测试
