冗余扩容

首先，初始化配置FastDFS基础环境，然后开始配置

1. 安装 libfastcommon 和 fasdfs 
2. 安装 nginx 并配置
3. 配置 strorage和client、nginx模块
4. 启动 fdfs_storaged 和 nginx 服务 
5. 观察日志和集群中新机的状态(ACTIVE 表示可以正常提供服务)

配置Storage

关键配置项: /etc/fdfs/storage.conf

* group_name=G1
* store_path_count=1
* store_path0=/data/fastdfs/storage/f_data
* tracker_server=192.168.2.30:22122
* tracker_server=192.168.2.20:22122
* http.server_port=8888

配置Client

关键配置项: /etc/fdfs/client.conf

* base_path=/data/fastdfs/tracker
* tracker_server=192.168.2.20:22122
* tracker_server=192.168.2.30:22122

配置Nginx模块

关键配置项: /etc/fdfs/mod_fastdfs.conf

* tracker_server=192.168.2.30:22122
* tracker_server=192.168.2.20:22122
* storage_server_port=23000
* group_name=G1
* url_have_group_name = true
* store_path_count=1
* store_path0=/data/fastdfs/storage/f_data

配置Nginx模块

虚拟主机配置

server {
   listen       8888;
   server_name  localhost;
   location /G1/M00 {
      root /data/fastdfs/storage/f_data;
      ngx_fastdfs_module;
   }
}

启动服务

启动Storage

# /etc/init.d/fdfs_storaged start

启动Nginx

# /usr/local/nginx/sbin/nginx

检查状态

# fdfs_monitor /etc/fdfs/client.conf
