    一、      安装

    (一)         下载FastDFS安装包

    FastDFS官方论坛:http://www.csource.org

    下载1:http://sourceforge.net/projects/fastdfs/files/

    下载2:https://code.google.com/p/fastdfs/downloads/list

    本手册使用CentOS 6.5 x86_64版操作系统,按照以下网络结构进行部署:

    所需要下载的压缩包有:

    FastDFS源代码:FastDFS_v5.01.tar.gz

    nginx模块源代码:fastdfs-nginx-module_v1.15.tar.gz

    nginx服务器源代码:nginx-1.4.7.tar.gz

    nginx cache purge插件源代码:ngx_cache_purge-2.1.tar.gz

    nginx依赖的pcre库源代码:pcre-8.34.tar.gz

    nginx依赖的zlib库源代码:zlib-1.2.8.tar.gz

    (二)         安装tracker

    1.      安装

    首先在172.16.1.202上安装FastDFS tracker,使用FastDFS_v5.01.tar.gz源代码包。

    可以直接从Linux系统下载源代码包并解压安装。如果是在Windows系统下载,可以在Linux系统中挂载Windows的共享目录并且将源代码包复制进Linux系统内。挂载命令如下

    [root@centos-db01 ~]# mount -o ro //Windows主机的IP地址/共享目录名/挂载目标目录

    l  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

    [root@tracker opt]# cp FastDFS_v5.01.tar.gz /usr/local/src/

    [root@tracker opt]# cd /usr/local/src/

    [root@tracker src]# tar zxf FastDFS_v5.01.tar.gz

    [root@tracker src]# cd FastDFS

    [root@tracker FastDFS]# ll

    l  运行make.sh,确认make成功。期间如果有错误,可能会是缺少依赖的软件包,需安装后再次make。

    [root@tracker FastDFS]# ./make.sh

    l  运行make.shinstall,确认install成功。

    [root@tracker FastDFS]# ./make.sh install

    安装完成后,所有可执行文件在/usr/local/bin下,以fdfs开头:

    [root@tracker FastDFS]# ll /usr/local/bin/fdfs*

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

    l  至此tracker安装完成。

    2.      配置

    l  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

    l  运行tracker之前,先要把防火墙中对应的fd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]

    l  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

    也可查看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

    l  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 storage,使用FastDFS_v5.01.tar.gz源代码包。

    l  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

    [root@storage1opt]# cp FastDFS_v5.01.tar.gz /usr/local/src/

    [root@storage1opt]# cd /usr/local/src/

    [root@storage1src]# tar zxf FastDFS_v5.01.tar.gz

    [root@storage1src]# cd FastDFS

    tracker_server=172.16.1.202:22122#tracker服务器的IP地址和端口号

    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

    l  运行storage之前,先要把防火墙中对应的端口打开(本例中为23000)。

    [root@storage1 FastDFS]# iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 23000 -j ACCEPT

    [root@storage1FastDFS]# /etc/init.d/iptables save

    iptables:将防火墙规则保存到 /etc/sysconfig/iptables:[确定]

    l  启动storage,会根据配置文件的设置自动创建多级存储目录,确认启动是否成功。(查看是否对应端口23000是否开始监听)

    [root@storage1 FastDFS]#/usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf restart

    data path: /fdfs/storage/data, mkdir sub dir...

    mkdir data path: 00 ...

    mkdir data path: 01 ...

    mkdir data path: 02 ...

    mkdir data path: 03 ...

    ...

    data path: /fdfs/storage/data, mkdir sub dir done.

    [root@storage1 FastDFS]#netstat -unltp | grep fdfs

    tcp    0    0.0.0.0:23000       0.0.0.0:*           LISTEN      1766/fdfs_storaged

    也可查看storage的日志是否启动成功或是否有错误。

    [root@storage1 FastDFS]#cat /fdfs/storage/logs/storaged.log

     

    确认启动成功后,可以运行fdfs_monitor查看storage服务器是否已经登记到tracker服务器。

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

    l  设置开机自动启动。

    [root@storage1 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

    l  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。(需要安装ngx_cache_purge-2.1.tar.gz)

    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。

    l  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

    [root@storage1opt]# cp nginx-1.4.7.tar.gz /usr/local/src

    [root@storage1opt]# cp fastdfs-nginx-module_v1.15.tar.gz /usr/local/src

    [root@storage1opt]# cp pcre-8.34.tar.gz /usr/local/src

    [root@storage1opt]# cp zlib-1.2.8.tar.gz /usr/local/src

    l  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

    l  运行make进行编译,确保编译成功。

    [root@storage1 nginx-1.4.7]#make

    l  运行makeinstall进行安装。

    [root@storage1 nginx-1.4.7]#make install

    l  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:

    [root@storage1 nginx-1.4.7]# ll /usr/local/nginx/

    总用量 16

    drwxr-xr-x. 2 root root 4096 3月  26 03:11 conf

    drwxr-xr-x. 2 root root 4096 3月  26 03:11 html

    drwxr-xr-x. 2 root root 4096 3月  26 03:11 logs

    drwxr-xr-x. 2 root root 4096 3月  26 03:11 sbin

    l  至此nginx以及FastDFS的nginx插件模块安装完成。

    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

    l  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/

    l  至此,nginx以及FastDFS插件模块设置完成。

    3.      运行

    l  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@storage1nginx-1.4.7]# iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 8080 -j ACCEPT

    [root@storage1nginx-1.4.7]# /etc/init.d/iptables save

    iptables:将防火墙规则保存到 /etc/sysconfig/iptables:[确定]

    l  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

    也可查看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

    ngx_http_fastdfs_process_init pid=40640

    [2014-03-26 03:47:17] INFO - local_host_ip_count: 2,  127.0.0.1  172.16.1.203

    [2014-03-26 03:47:17] INFO - fastdfs apache / nginx module v1.15, response_mode=proxy, base_path=/tmp, url_have_group_name=1, group_count=3, connect_timeout=2, network_timeout=30, tracker_server_count=1, if_alias_prefix=, local_host_ip_count=2, need_find_content_type=1, default_content_type=application/octet-stream, anti_steal_token=0, token_ttl=0s, anti_steal_secret_key length=0, token_check_fail content_type=, token_check_fail buff length=0, load_fdfs_parameters_from_tracker=1, storage_sync_file_max_delay=86400s, use_storage_id=0, storage server id count=0, flv_support=1, flv_extension=flv

    [2014-03-26 03:47:17] INFO - group 1. group_name=group1, storage_server_port=23000, path_count=1, store_path0=/fdfs/storage

    [2014-03-26 03:47:17] INFO - group 2. group_name=group2, storage_server_port=23000, path_count=1, store_path0=/fdfs/storage

    [2014-03-26 03:47:17] INFO - group 3. group_name=group3, storage_server_port=23000, path_count=1, store_path0=/fdfs/storage

    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。

    l  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tracker上安装的nginx主要为了提供http访问的反向代理、负载均衡以及缓存服务。

    1.      安装

    l  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

    [root@trackeropt]# cp nginx-1.4.7.tar.gz /usr/local/src

    [root@tracker opt]# cp ngx_cache_purge-2.1.tar.gz /usr/local/src

    [root@tracker opt]# cp pcre-8.34.tar.gz /usr/local/src

    [root@tracker opt]# cp zlib-1.2.8.tar.gz /usr/local/src

    [root@tracker opt]# cd /usr/local/src/

    [root@tracker src]# tar zxf nginx-1.4.7.tar.gz

    [root@tracker src]# tar zxf ngx_cache_purge-2.1.tar.gz

    [root@tracker src]# tar zxf pcre-8.34.tar.gz

    [root@tracker src]# tar zxf zlib-1.2.8.tar.gz

    [root@tracker src]# cd nginx-1.4.7

    [root@tracker nginx-1.4.7]# ll

    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@storage1 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

            }  

    l  至此,nginx以及nginx cachepurge插件模块设置完成。

    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@trackernginx-1.4.7]# iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 8080 -j ACCEPT

    [root@trackernginx-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@trackernginx-1.4.7]# /usr/local/nginx/sbin/nginx

    ngx_http_fastdfs_set pid=40638

    [root@trackernginx-1.4.7]# netstat -unltp | grep nginx

    tcp    0    0.0.0.0:8080            0.0.0.0:*              LISTEN      40639/nginx

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

    [root@trackernginx-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

    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@trackernginx-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:

    可以看到文件被正确读取出来了。

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

    [root@trackernginx-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

    如果要手动清除缓存,可以在文件URL之前加上purge:

    l  设置开机自动启动。

    [root@trackernginx-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

    至此,tracker服务器上的http反向代理+负载均衡+缓存已经安装完成。

    二、      使用

    1.      上传文件

    FastDFS提供了多种方式上传文件:

    l  使用fdfs_upload_file上传(之前已经有演示)

    l  使用C语言客户端接口上传

    l  使用PHP客户端接口上传

    l  使用Java客户端接口上传

    l  使用Python客户端接口上传

    l  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

    l  使用fdfs_download_file通过tracker服务器下载

    l  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

    l  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
