        -rw-r--r--. 1 root root  6989 3月  13 15:15 tracker.conf

        2. 配置

        编辑配置文件目录下的tracker.conf,设置相关信息并保存

        [root@tracker FastDFS]# vim /etc/fdfs/tracker.conf
        
        
        
        #一般只需改动以下几个参数即可:
        
        disabled=false            #启用配置文件
        
        port=22122                #设置tracker的端口号
        
        base_path=/fdfs/tracker   #设置tracker的数据文件和日志目录(需预先创建)
        
        http.server_port=8080     #设置http端口号
        
        #如需要进行性能调优,可以参照附录的配置文件的详细说明。

        3. 运行

        运行tracker之前,先要把防火墙中对应的端口打开(本例中为22122)

        [root@tracker FastDFS]# iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 22122 -j ACCEPT
        
        [root@tracker FastDFS]# /etc/init.d/iptables save
        
        iptables:将防火墙规则保存到 /etc/sysconfig/iptables:[确定]

        启动tracker,确认启动是否成功。(查看是否对应端口22122是否开始监听)

        [root@tracker FastDFS]# /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart
        
        [root@tracker FastDFS]# netstat -unltp | grep fdfs
        
        tcp    0    0.0.0.0:22122       0.0.0.0:*           LISTEN      1766/fdfs_trackerd

        可查看tracker的日志是否启动成功或是否有错误

        [root@tracker FastDFS]# cat /fdfs/tracker/logs/trackerd.log

        设置开机自动启动

        [root@tracker FastDFS]# vim /etc/rc.d/rc.local
        
        
        
        将运行命令行添加进文件:/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart

        (三)安装Storage

        1. 安装

        首先在172.16.1.203上安装FastDFS tracker,使用FastDFS_v5.01.tar.gz源代码包。

        1. 首先将代码包复制到系统的/usr/local/src内(这一步可选),然后使用tar命令解压
        2. [root@storage1 opt]# cp FastDFS_v5.01.tar.gz /usr/local/src/
          
          [root@storage1 opt]# cd /usr/local/src/
          
          [root@storage1 src]# tar zxf FastDFS_v5.01.tar.gz
          
          [root@storage1 src]# cd FastDFS

                      total_file_read_count = 0
              
                      success_file_read_count = 0
              
                      total_file_write_count = 0
              
                      success_file_write_count = 0
              
                      last_heart_beat_time = 2014-03-26 01:51:03
              
                      last_source_update = 1970-01-01 08:00:00

                      last_synced_timestamp = 1970-01-01 08:00:00

              看到“172.16.1.203 ACTIVE”即可确认storage运行正常。

               

              设置开机自动启动

              [root@storage FastDFS]# vim /etc/rc.d/rc.local
              
              
              
              将运行命令行添加进文件:

              /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf restart

              之后依次在172.16.1.204~208上全部安装上storage并确认运行正常。注意配置文件中group名参数需要根据实际情况调整,本例中group是这样分配的:

              group1:172.16.1.203,172.16.1.204

              group2:172.16.1.205,172.16.1.206

              group3:172.16.1.207,172.16.1.208

              另外每个group中所有storage的端口号必须一致。

              (四) 在storage上安装nginx

              在storage上安装的nginx主要为了提供http的访问服务,同时解决group中storage服务器的同步延迟问题。

              1. 安装

              首先在172.16.1.203上安装nginx,使用nginx-1.4.7.tar.gz源代码包以及FastDFS的nginx插件fastdfs-nginx-module_v1.15.tar.gz。

              首先将代码包和插件复制到系统的/usr/local/src内(可选),然后使用tar命令解压

              运行./configure进行安装前的设置,主要设置安装路径、FastDFS插件模块目录、pcre库目录、zlib库目录。

              如果提示错误,可能缺少依赖的软件包,需先安装依赖包,再次运行./configure

              [root@storage1 nginx-1.4.7]# ./configure --prefix=/usr/local/nginx --add-module=/usr/local/src/fastdfs-nginx-module/src --with-pcre=/usr/local/src/pcre-8.34/ --with-zlib=/usr/local/src/zlib-1.2.8

              运行make进行编译,确保编译成功。运行make install进行安装

              [root@storage1 nginx-1.4.7]# make
              
              [root@storage1 nginx-1.4.7]# make install

              将FastDFS的nginx插件模块的配置文件copy到FastDFS配置文件目录。

              [root@storage1 nginx-1.4.7]# cp /usr/local/src/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/
              安装完成后,nginx所有文件在/usr/local/nginx下

              2. 配置

              l 编辑/usr/local/nginx/conf配置文件目录下的nginx.conf,设置添加storage信息并保存。

              [root@storage1 nginx-1.4.7]# vim /usr/local/nginx/conf/nginx.conf
              将server段中的listen端口号改为8080:
              
              listen       8080;
              
              在server段中添加:
              
              location ~/group[1-3]/M00 {
              
                  root /fdfs/storage/data;
              
                  ngx_fastdfs_module;
              
              }

              l 编辑/etc/fdfs配置文件目录下的mod_fastdfs.conf,设置storage信息并保存。

              [root@storage1 nginx-1.4.7]# vim /etc/fdfs/mod_fastdfs.conf
              
              
              
              一般只需改动以下几个参数即可:
              
              base_path=/fdfs/storage           #保存日志目录
              
              tracker_server=172.16.1.202:22122 #tracker服务器的IP地址以及端口号
              
              storage_server_port=23000         #storage服务器的端口号
              
              group_name=group1                 #当前服务器的group名
              
              url_have_group_name = true        #文件url中是否有group名
              
              store_path_count=1                #存储路径个数,需要和store_path个数匹配
              
              store_path0=/fdfs/storage         #存储路径
              
              http.need_find_content_type=true  #从文件扩展名查找文件类型(nginx时为true)
              
              group_count = 3                   #设置组的个数
              
              在末尾增加3个组的具体信息:
              
              [group1]
              
              group_name=group1
              
              storage_server_port=23000
              
              store_path_count=1
              
              store_path0=/fdfs/storage
              
              
              
               [group2]
              
              group_name=group2
              
              storage_server_port=23000
              
              store_path_count=1
              
              store_path0=/fdfs/storage
              
              
              
              [group3]
              
              group_name=group3
              
              storage_server_port=23000
              
              store_path_count=1
              
              store_path0=/fdfs/storage

              建立M00至存储目录的符号连接

              [root@storage1 nginx-1.4.7]# ln -s /fdfs/storage/data /fdfs/storage/data/M00
              
              [root@storage1 nginx-1.4.7]# ll /fdfs/storage/data/M00
              
              lrwxrwxrwx. 1 root root 19 3月 26 03:44 /fdfs/storage/data/M00 -> /fdfs/storage/data/

              3. 运行

              运行nginx之前,先要把防火墙中对应的端口打开(本例中为8080)

              [root@storage1 nginx-1.4.7]# iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 8080 -j ACCEPT
              
              [root@storage1 nginx-1.4.7]# /etc/init.d/iptables save
              
              iptables:将防火墙规则保存到 /etc/sysconfig/iptables:[确定]

              启动nginx,确认启动是否成功。(查看是否对应端口8080是否开始监听)

              [root@storage1 nginx-1.4.7]# /usr/local/nginx/sbin/nginx
              
              ngx_http_fastdfs_set pid=40638
              
              [root@storage1 nginx-1.4.7]# netstat -unltp | grep nginx
              
              tcp    0    0.0.0.0:8080            0.0.0.0:*              LISTEN      40639/nginx

              查看nginx的日志是否启动成功或是否有错误。

              [root@storage1 nginx-1.4.7]# cat /usr/local/nginx/logs/error.log

              在error.log中没有错误,既启动成功。可以打开浏览器,直接访问http://172.16.1.203:8080,查看是否弹出nginx欢迎页面。

              之后依次在172.16.1.204~208上全部安装上nginx并确认运行正常。

              设置开机自动启动。

              [root@storage1 nginx-1.4.7]# vim /etc/rc.d/rc.local
              
              将运行命令行添加进文件:/usr/local/nginx/sbin/nginx

              (五)在tracker上安装nginx

              在storage上安装的nginx主要为了提供http的访问服务,同时解决group中storage服务器的同步延迟问题。

              1. 安装

              首先在172.16.1.203上安装nginx,使用nginx-1.4.7.tar.gz源代码包以及FastDFS的nginx插件fastdfs-nginx-module_v1.15.tar.gz。

              首先将代码包和插件复制到系统的/usr/local/src内(可选),然后使用tar命令解压

              l 运行./configure进行安装前的设置,主要设置安装路径、nginx cache purge插件模块目录、pcre库目录、zlib库目录。

              如果提示错误,可能缺少依赖的软件包,需先安装依赖包,再次运行./configure

              [root@tracker nginx-1.4.7]# ./configure --prefix=/usr/local/nginx --add-module=/usr/local/src/ngx_cache_purge-2.1 --with-pcre=/usr/local/src/pcre-8.34/ --with-zlib=/usr/local/src/zlib-1.2.8

              运行make进行编译,确保编译成功。运行make install进行安装

              [root@tracker nginx-1.4.7]# make
              
              [root@tracker nginx-1.4.7]# make install

              2. 配置

              编辑/usr/local/nginx/conf配置文件目录下的nginx.conf,设置添加storage信息并保存。

              [root@tracker nginx-1.4.7]# vim /usr/local/nginx/conf/nginx.conf
              worker_processes  4;                  #根据CPU核心数而定
              
              events {
              
                  worker_connections  65535;        #最大链接数
              
                  use epoll;                        #新版本的Linux可使用epoll加快处理性能
              
              }
              
              http {
              
              #设置缓存参数
              
                  server_names_hash_bucket_size 128;
              
                  client_header_buffer_size 32k;
              
                  large_client_header_buffers 4 32k;
              
                  client_max_body_size 300m;

                      location ~ /purge(/.*) {
              
                          allow 127.0.0.1;
              
                          allow 172.16.1.0/24;
              
                          deny all;
              
                          proxy_cache_purge http-cache  $1$is_args$args;
              
                      }

              3. 运行

              运行nginx之前,先要把防火墙中对应的端口打开(本例中为8080)

              [root@tracker nginx-1.4.7]# iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 8080 -j ACCEPT
              
              [root@tracker nginx-1.4.7]# /etc/init.d/iptables save
              
              iptables:将防火墙规则保存到 /etc/sysconfig/iptables:[确定]

              启动nginx,确认启动是否成功。(查看是否对应端口8080是否开始监听)

              [root@tracker nginx-1.4.7]# /usr/local/nginx/sbin/nginx
              
              ngx_http_fastdfs_set pid=40638
              
              [root@tracker nginx-1.4.7]# netstat -unltp | grep nginx
              
              tcp    0    0.0.0.0:8080            0.0.0.0:*              LISTEN      40639/nginx

              尝试上传一个文件到FastDFS,然后访问试试。先配置client.conf文件

              [root@tracker nginx-1.4.7]# vim /etc/fdfs/client.conf
              
              修改以下参数:
              
              base_path=/fdfs/tracker                    #日志存放路径
              
              tracker_server=172.16.1.202:22122          #tracker服务器IP地址和端口号
              
              http.tracker_server_port=8080              #tracker服务器的http端口号

              4. 上传

              使用/usr/local/bin/fdfs_upload_file上传一个文件,程序会自动返回文件的URL

              [root@tracker nginx-1.4.7]# /usr/local/bin/fdfs_upload_file /etc/fdfs/client.conf /mnt/monk.jpg
              
              group3/M00/00/00/rBABz1MzKG6Ad_hBAACKLsUDM60560.jpg

              然后使用浏览器访问:

              http://172.16.1.202:8080/group3/M00/00/00/rBABz1MzKG6Ad_hBAACKLsUDM60560.jpg

              查看nginx的access.log日志,可以看到访问返回200成功。

              [root@tracker nginx-1.4.7]# tail -n 10 -f /usr/local/nginx/logs/access.log
              
              172.16.1.201 - - [26/Mar/2014:13:15:00 +0800] "GET /group3/M00/00/00/rBABz1MzKG6Ad_hBAACKLsUDM60560.jpg HTTP/1.1" 200 35374 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko"
              查看nginx的cache目录,可以看到已经生成了缓存文件
              [root@tracker nginx-1.4.7]# ll /var/cache/nginx/proxy_cache/ -R
              
              /var/cache/nginx/proxy_cache/:
              
              总用量 8
              
              drwx------. 3 nobody nobody 4096 3月  26 12:57 6
              
              drwxr-xr-x. 2 nobody root   4096 3月  26 13:14 tmp
              
              
              
              /var/cache/nginx/proxy_cache/6:
              
              总用量 4
              
              drwx------. 2 nobody nobody 4096 3月  26 13:08 11
              
              
              
              /var/cache/nginx/proxy_cache/6/11:
              
              总用量 36
              
              -rw-------. 1 nobody nobody 35686 3月  26 13:08 b1f6fb1f7266f796765b6d6965021116

              如果要手动清除缓存,可以在文件URL之前加上purge:

              http://172.16.1.202:8080/purge/group3/M00/00/00/rBABz1MzKG6Ad_hBAACKLsUDM60560.jpg

              设置开机自动启动。

              [root@tracker nginx-1.4.7]# vim /etc/rc.d/rc.local
              
              将运行命令行添加进文件:/usr/local/nginx/sbin/nginx

              二、使用

              1. 上传文件

              FastDFS提供了多种方式上传文件:

              • 使用fdfs_upload_file上传(之前已经有演示)
              • 使用C语言客户端接口上传
              • 使用PHP客户端接口上传
              • 使用Java客户端接口上传
              • 使用Python客户端接口上传
              • 使用.NET客户端接口上传

              根据具体情况选择使用。上传均支持断点续传。

              2. 下载文件

              • 使用fdfs_download_file通过tracker服务器下载
              • 使用nginx通过http方式直接从storage下载(支持断点续传,作者推荐)

              3. 监视服务器资源

              使用fdfs_monitor查看tracker和所有group的运行情况。

              [root@tracker tmp]# /usr/local/bin/fdfs_monitor /etc/fdfs/client.conf
