• 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
    1. 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  
      
      
    2. 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
      
    3. 启动tracker(支持start|stop|restart):

      /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start
      
    4. 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)
      

      J5BqaR.png

    5. 查看端口情况:netstat -apn|grep fdfs

    J5BVu4.png

    ④配置Storage服务
    1. 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
      
      
    2. 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
      
    3. 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
      
    4. 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
    1. 下载Nginx安装包

      wget http://nginx.org/download/nginx-1.15.2.tar.gz
      
    2. 下载fastdfs-nginx-module安装包

      wget https://github.com/happyfish100/fastdfs-nginx-module/archive/V1.20.tar.gz
      
    3. 解压nginx:

      tar -zxvf nginx-1.15.2.tar.gz
      
    4. 解压fastdfs-nginx-module:

      tar -xvf V1.20.tar.gz
      
    5. 进入nginx目录:

      cd nginx-1.15.2
      
    6. 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
          
          
      
    7. 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/
      
    8. 编译安装:

      make
      make install
      
    9. 查看安装路径:

      whereis nginx
      

      J5coM6.png

    10. 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
      
    11. 验证启动状态:

      wget "http://127.0.0.1"
      

      J5gEJs.png

    12. 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
    1. 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
      
    2. 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
      
    3. 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;
              }
      
    4. 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。
