FastDFS的搭建和相关使用
1.简介
FastDFS是一个开源的高性能分布式文件系统。它的主要功能包括:文件存储,文件同步和文件访问(文件上传和文件下载),它可以解决高容量和负载平衡问题。 FastDFS应该满足基于照片共享站点和视频共享站点等文件的网站的要求。

2.fastDfs的搭建
操作环境:CentOS7 X64,以下操作都是单机环境。
服务列表:
hostname | ip | Node Type | username |
---|---|---|---|
m1 | 192.168.142.128 | tracker server,storage server | root |
m2 | 192.168.142.134 | tracker server,storage server | root |
①安装libfastcommon
获取libfastcommon安装包:
wget https://github.com/happyfish100/libfastcommon/archive/V1.0.38.tar.gz
解压安装包:
tar -zxvf V1.0.38.tar.gz
进入目录:
cd libfastcommon-1.0.38
执行编译:
./make.sh
安装:
./make.sh install
②安装FastDFS
获取fdfs安装包:
wget https://github.com/happyfish100/fastdfs/archive/V5.11.tar.gz
解压安装包:
tar -zxvf V5.11.tar.gz
进入目录:
cd fastdfs-5.11
执行编译:
./make.sh
安装:
./make.sh install
查看可执行命令:
ls -la /usr/bin/fdfs*
③配置Tracker服务
-
进入/etc/fdfs目录,有三个.sample后缀的文件(自动生成的fdfs模板配置文件),通过cp命令拷贝tracker.conf.sample,删除.sample后缀作为正式文件:
cd /etc/fdfs/ cp tracker.conf.sample tracker.conf
-
编辑tracker.conf:vi tracker.conf,修改相关参数
base_path=/data/log/fastdfs/tracker #tracker存储data和log的跟路径,必须提前创建好 port=22122 #tracker默认22122 http.server_port=80 #http端口,需要和nginx相同
-
启动tracker(支持start|stop|restart):
/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start
-
查看tracker启动日志:进入刚刚指定的base_path(/data/log/fastdfs/tracker)中有个logs目录,查看tracker.log文件
tail -200f /data/log/fastdfs/tracker/logs/trackerd.log![J5BqaR.png](https://s1.ax1x.com/2020/04/28/J5BqaR.png)
-
查看端口情况:netstat -apn|grep fdfs
④配置Storage服务
-
进入/etc/fdfs目录,有cp命令拷贝storage.conf.sample,删除.sample后缀作为正式文件;
cd /etc/fdfs/ cp storage.conf.sample storage.conf
-
编辑storage.conf:vi storage.conf,修改相关参数:
base_path=/data/log/fastdfs/storage #storage存储data和log的跟路径,必须提前创建好 port=23000 #storge默认23000,同一个组的storage端口号必须一致 group_name=group1 #默认组名,根据实际情况修改 store_path_count=1 #存储路径个数,需要和store_path个数匹配 store_path0=/data/log/fastdfs/storage #如果为空,则使用base_path tracker_server=192.168.142.128:22122 #配置该storage监听的tracker的ip和port
-
启动storage(支持start|stop|restart):
/usr/bin/fdfs_storaged /etc/fdfs/storage.conf start // 如果现实文件夹不存在 则使用下面命令新建 mkdir -p /data/log/fastdfs/storage
-
查看storage启动日志:进入刚刚指定的base_path(/data/log/fastdfs/storage)中有个logs目录,查看storage.log文件
tail -200f /data/log/fastdfs/storage/logs/storaged.log
5.此时再查看tracker日志:发现已经开始选举,并且作为唯一的一个tracker,被选举为leader
6.查看端口情况:
netstat -apn|grep fdfs
7.通过monitor来查看storage是否成功绑定:
/usr/bin/fdfs_monitor /etc/fdfs/storage.conf
⑤安装Nginx和fastdfs-nginx-module模块
-
下载Nginx安装包
wget http://nginx.org/download/nginx-1.15.2.tar.gz
-
下载fastdfs-nginx-module安装包
wget https://github.com/happyfish100/fastdfs-nginx-module/archive/V1.20.tar.gz
-
解压nginx:
tar -zxvf nginx-1.15.2.tar.gz
-
解压fastdfs-nginx-module:
tar -xvf V1.20.tar.gz
-
进入nginx目录:
cd nginx-1.15.2
-
安装依赖的库
// 命令找不到请先安装gcc yum -y install gcc // centos请使用如下命令 yum update yum install libpcre3 libpcre3-dev openssl libssl-dev libperl-dev // ubuntu使用如下命令 apt-get update apt-get install libpcre3 libpcre3-dev openssl libssl-dev libperl-dev
-
配置,并加载fastdfs-nginx-module模块:
./configure --prefix=/usr/local/nginx --add-module=/usr/local/src/fastdfs-nginx-module-1.20/src/
-
编译安装:
make make install
-
查看安装路径:
whereis nginx
-
启动、停止:
cd /usr/local/nginx/sbin/ ./nginx ./nginx -s stop #此方式相当于先查出nginx进程id再使用kill命令强制杀掉进程 ./nginx -s quit #此方式停止步骤是待nginx进程处理任务完毕进行停止 ./nginx -s reload
-
验证启动状态:
wget "http://127.0.0.1"
-
查看此时的nginx版本:发现fastdfs模块已经安装好了
⑥配置Nginx和fastdfs-nginx-module模块
-
配置mod-fastdfs.conf,并拷贝到/etc/fdfs文件目录下
cd /data/fastdfs cd fastdfs-nginx-module-1.20/src/ cp mod_fastdfs.conf /etc/fdfs
-
进入/etc/fdfs修改mod-fastdfs.conf:
base_path=/data/log/fastdfs tracker_server=192.168.142.128:22122 #tracker的地址 url_have_group_name=true #url是否包含group名称 storage_server_port=23000 #需要和storage配置的相同 store_path_count=1 #存储路径个数,需要和store_path个数匹配 store_path0=/data/fastdfs/storage #文件存储的位置
-
配置nginx,80端口server增加location如图:
cd /usr/local/nginx/conf/ vim nginx.conf
location ~/group[0-9]/ { root /data/fastdfs/storage; ngx_fastdfs_module; }
-
最后需要拷贝fastdfs解压目录中的http.conf和mime.types:
cd /data/fastdfs/fastdfs-5.11/conf cp mime.types http.conf /etc/fdfs/
5.刷新nginx
cd /usr/local/nginx/sbin
./nginx -s reload
⑦相关问题
返回错误码28,表示磁盘空间不足。注意FastDFS中有预留空间的概念,在tracker.conf中设置,配置项为:reserved_storage_space,缺省值为4GB,即预留4GB的空间。请酌情设置reserved_storage_space这个参数,比如可以设置为磁盘总空间的20%左右。
