一、简介
FastDFS服务端有两个角色：跟踪器（tracker）和存储节点（storage）。跟踪器主要做调度工作，在访问上起负载均衡的作用。
2.2、FastDFS系统结构图
3.2、编译环境：
yum install git gcc gcc-c++ make automake autoconf libtool pcre pcre-devel zlib zlib-devel openssl-devel wget vim -y
4.1、修改tracker配置文件
vim /etc/fdfs/tracker.conf
# 修改的内容如下：
disabled=false # 启用配置文件
port=22122 # tracker服务器端口（默认22122）
base_path=/home/dfs # 存储日志和数据的根目录
store_lookup=0 # 轮询方式上传
4.2、启动tracker服务器
cp /usr/local/src/fastdfs/init.d/fdfs_storaged
chmod +x /etc/rc.d/init.d/fdfs_trackerd
/etc/init.d/fdfs_trackerd start
或者
systemctl start fdfs_trackerd
或者
fdfs_trackerd /etc/fdfs/tracker.conf start
初次启动，会在/data/fastdfs/tracker目录下生成logs、data两个目录。
drwxr-xr-x 2 root root 178 May 3 22:34 data
drwxr-xr-x 2 root root 26 May 2 18:57 logs
检查FastDFS Tracker Server是否启动成功：
ps aux | grep fdfs_trackerd
4.3、tracker server的关闭命令
/etc/init.d/fdfs_trackerd stop
或者
systemctl stop fdfs_trackerd
或者
fdfs_trackerd /etc/fdfs/tracker.conf stop
4.4、设置tracker server开机启动
chkconfig fdfs_trackerd on
配置文件准备：cp /etc/fdfs/storage.conf.sample /etc/fdfs/storage.conf
4.5、192.168.56.11、192.168.56.12修改storage配置文件
vim /etc/fdfs/storage.conf
# 修改的内容如下：
disabled=false # 启用配置文件
port=23000 # storage的端口号,同一个组的 storage 端口号必须相同
group_name=group1
base_path=/home/dfs # 存储日志和数据的根目录
store_path0=/home/dfs # 第一个存储目录
store_path_count=1 #存储路径个数，需要和store_path个数匹配
tracker_server=192.168.56.40:22122 # tracker服务器的IP地址和端口
tracker_server=192.168.56.45:22122 # 多个tracker直接添加多条配置
配置group_name
不同分组配置不同group_name，第一组为group1， 第二组为group2
4.6、192.168.56.13、192.168.56.14修改storage配置文件
vim /etc/fdfs/storage.conf
# 修改的内容如下：
disabled=false # 启用配置文件
port=23000 # storage的端口号,同一个组的 storage 端口号必须相同
group_name=group2
base_path=/home/dfs # 存储日志和数据的根目录
store_path0=/home/dfs # 第一个存储目录
store_path_count=1 #存储路径个数，需要和store_path个数匹配
tracker_server=192.168.56.40:22122 # tracker服务器的IP地址和端口
tracker_server=192.168.56.45:22122 # 多个tracker直接添加多条配置
4.7、启动storage服务器
/etc/init.d/fdfs_storaged start
或者
systemctl start fdfs_storaged
或者
fdfs_storaged /etc/fdfs/tracker.conf start
初次启动，会在/home/dfs目录下生成logs、data两个目录。
drwxr-xr-x 259 root root 8192 May 3 23:06 data
drwxr-xr-x 2 root root 26 May 2 19:12 logs
检查FastDFS Tracker Server是否启动成功：
ps aux | grep fdfs_storaged
所有 Storage 节点都启动之后，可以在任一 Storage 节点上使用如下命令查看集群信息：
/usr/bin/fdfs_monitor /etc/fdfs/storage.conf
