前言

本文基于CentOS6.5安装

FastDFS方案

环境准备

下载软件：

• libfastcommon-master.zip
• FastDFS_v5.05.tar
• fastdfs-nginx-module_v1.16.tar
• fastdfs_client_v1.24.jar

安装gcc

命令：yum install make cmake gcc gcc-c++

解压libfastcommon

命令：unzip libfastcommon-master.zip -d /usr/local/fast/

关闭防火墙

在学习时可以不用考虑防火墙的问题

正文

安装libfastcommon

./make.sh 
./make.sh install
mkdir -p /usr/lib64
install -m 755 libfastcommon.so /usr/lib64
mkdir -p /usr/include/fastcommon

打印：

install -m 644 common_define.h hash.h chain.h logger.h base64.h shared_func.h pthread_func.h ini_file_reader.h _os_bits.h sockopt.h sched_thread.h http_func.h md5.h local_ip_func.h avl_tree.h ioevent.h ioevent_loop.h fast_task_queue.h fast_timer.h process_ctrl.h fast_mblock.h connection_pool.h /usr/include/fastcommon

注意安装的路径：libfastcommon默认安装到了/usr/lib64/这个位置。

进行软链接创建

ln -s /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so
ln -s /usr/lib64/libfdfsclient.so /usr/local/lib/libfdfsclient.so
ln -s /usr/lib64/libfdfsclient.so /usr/lib/libfdfsclient.so

安装FastDFS（同时进行）

解压

tar -zxvf FastDFS_v5.05.tar.gz -C /usr/local/fast/

安装

cd /usr/local/fast/FastDFS
./make.sh
./make.sh install

打印：

mkdir -p /usr/bin
mkdir -p /etc/fdfs
cp -f fdfs_trackerd /usr/bin
if [ ! -f /etc/fdfs/tracker.conf.sample ]; then cp -f ../conf/tracker.conf /etc/fdfs/tracker.conf.sample; fi
mkdir -p /usr/bin
mkdir -p /etc/fdfs
cp -f fdfs_storaged  /usr/bin
if [ ! -f /etc/fdfs/storage.conf.sample ]; then cp -f ../conf/storage.conf /etc/fdfs/storage.conf.sample; fi
mkdir -p /usr/bin
mkdir -p /etc/fdfs
mkdir -p /usr/lib64
cp -f fdfs_monitor fdfs_test fdfs_test1 fdfs_crc32 fdfs_upload_file fdfs_download_file fdfs_delete_file fdfs_file_info fdfs_appender_test fdfs_appender_test1 fdfs_append_file fdfs_upload_appender /usr/bin
if [ 0 -eq 1 ]; then cp -f libfdfsclient.a /usr/lib64; fi
if [ 1 -eq 1 ]; then cp -f libfdfsclient.so /usr/lib64; fi
mkdir -p /usr/include/fastdfs
cp -f ../common/fdfs_define.h ../common/fdfs_global.h ../common/mime_file_parser.h ../common/fdfs_http_shared.h ../tracker/tracker_types.h ../tracker/tracker_proto.h ../tracker/fdfs_shared_func.h ../storage/trunk_mgr/trunk_shared.h tracker_client.h storage_client.h storage_client1.h client_func.h client_global.h fdfs_client.h /usr/include/fastdfs
if [ ! -f /etc/fdfs/client.conf.sample ]; then cp -f ../conf/client.conf /etc/fdfs/client.conf.sample; fi

服务脚本在：

ls /etc/init.d/ | grep fdfs
fdfs_storaged
fdfs_trackerd

配置文件在：

ls /etc/fdfs/
client.conf.sample  storage.conf.sample  tracker.conf.sample

命令行工具在/usr/bin/目录下

ls /usr/bin/ | grep fdfs
fdfs_appender_test
fdfs_appender_test1
fdfs_append_file
fdfs_crc32
fdfs_delete_file
fdfs_download_file
fdfs_file_info
fdfs_monitor
fdfs_storaged
fdfs_test
fdfs_test1
fdfs_trackerd
fdfs_upload_appender
fdfs_upload_file

因为FastDFS服务脚本设置的bin目录为/usr/local/bin/下,但是实际我们安装在了/usr/bin/下面。所以我们需要修改FastDFS配置文件中的路径，也就是需要修改俩 个配置文件：

• 命令：vim /etc/init.d/fdfs_storaged
• 进行全局替换命令：%s+/usr/local/bin+/usr/bin
• 命令：vim /etc/init.d/fdfs_trackerd
• 进行全局替换命令：%s+/usr/local/bin+/usr/bin

配置跟踪器（trackerd）

修改配置文件

cd /etc/fdfs/
cp tracker.conf.sample tracker.conf
vim /etc/fdfs/tracker.conf

修改

# the base path to store data and log files
base_path=/fastdfs/tracker

mkdir -p /fastdfs/tracker

• 目录命令：cd /fastdfs/tracker/ && ll
• 启动tracker命令：/etc/init.d/fdfs_trackerd start
• 查看进程命令：ps -el | grep fdfs
• 停止tracker命令：/etc/init.d/fdfs_trackerd stop

查看是否启动成功

启动前：

cd /fastdfs/tracker/ && ll
total 0

启动

/etc/init.d/fdfs_trackerd start

启动成功

cd /fastdfs/tracker/ && ll
total 8
drwxr-xr-x. 2 root root 4096 Dec 14 20:48 data
drwxr-xr-x. 2 root root 4096 Dec 14 20:48 logs

可以设置开机启动跟踪器：（一般生产环境需要开机启动一些服务，如keepalived、Nginx、tomcat等等）

• 命令：vim /etc/rc.d/rc.local
• 加入配置：/etc/init.d/fdfs_trackerd start

配置FastDFS存储（storaged）

修改配置文件storage.conf

• 进入文件目录：cd /etc/fdfs/，进行copy storage文件一份
• 命令：cd /etc/fdfs/
• 命令：cp storage.conf.sample storage.conf
• 命令：vim /etc/fdfs/storage.conf

修改内容：

base_path=/fastdfs/storage
store_path0=/fastdfs/storage
tracker_server=192.168.1.1:22122
http.server_port=80

创建存储目录：

mkdir -p /fastdfs/storage

启动存储（storage）

命令：/etc/init.d/fdfs_storaged start

查看是否启动成功

ps -ef | grep fdfs

可以设置开机启动跟踪器：（一般生产环境需要开机启动一些服务，如keepaliv ed、linux、tomcat等等）

• 命令：vim /etc/rc.d/rc.local
• 加入配置：/etc/init.d/fdfs_storaged start

测试

首先我们在跟踪器（tracker）里copy一份client.conf文件。

命令：cd /etc/fdfs/

命令：cp client.conf.sample client.conf

编辑client.conf文件

vim /etc/fdfs/client.conf

修改内容：

base_path=/fastdfs/tracker
tracker_server=**192.168.1.1**:22122

测试上传

/usr/bin/fdfs_upload_file /etc/fdfs/client.conf /root/FastDFS/libfastcommon-master.zip

打印：

group1/M00/00/00/2-YyVlhRQlaAZLlgAAGP6hUWM6I411.zip

存储器查看文件

cd /fastdfs/storage/data/00/00/ && ll
total 1
-rw-r--r--. 1 root root 102378 Dec 14 21:00 2-YyVlhRQlaAZLlgAAGP6hUWM6I411.zip

FastDFS与Nginx整合（Storage）

解压Nginx

tar -zxvf nginx-1.6.2.tar.gz

安装fastdfs-nginx-module_v1.16.tar.gz

tar -zxvf FastDFS/fastdfs-nginx-module_v1.16.tar.gz -C /usr/local/fast/
cd /usr/local/fast/fastdfs-nginx-module/src/

编辑配置文件config

vim /usr/local/fast/fastdfs-nginx-module/src/config

修改前：
CORE_INCS="$CORE_INCS /usr/local/include/fastdfs /usr/local/include/fastcommon/"
修改后：
CORE_INCS="$CORE_INCS /usr/include/fastdfs /usr/include/fastcommon/"

FastDFS与Nginx进行集成

cd nginx-1.6.2/

./configure –add-module=/usr/local/fast/fastdfs-nginx-module/src/

make && make install

如报错 自行安装pcre

复制、修改配置文件

cp /usr/local/fast/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/

vim /etc/fdfs/mod_fastdfs.conf

connect_timeout=10
tracker_server=192.168.1.1:22122
url_have_group_name = true
store_path0=/fastdfs/storage

复制FastDFS里的2个文件

cd /usr/local/fast/FastDFS/conf/

cp http.conf mime.types /etc/fdfs/

建立软连接

ln -s /fastdfs/storage/data/ /fastdfs/storage/data/M00

修改Nginx配置

vim nginx.conf

listen 80;
server_name localhost;
location ~/group([0-9])/M00 {
    ngx_fastdfs_module;
}

启动Nginx

/usr/local/nginx/sbin/nginx

报错: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

• 32位系统 ln -s /usr/local/lib/libpcre.so.1 /lib
• 64位系统ln -s /usr/local/lib/libpcre.so.1 /lib64

测试

访问 http://192.168.1.2/group1/M00/00/00/2-YyVlhRQlaAZLlgAAGP6hUWM6I411.zip

• 启动停止命令
• 启动命令： 启动tracker命令：/etc/init.d/fdfs_trackerd start
• 查看进程命令：ps -el | grep fdfs
• 启动storage命令：/etc/init.d/fdfs_storaged start
• 查看进程命令：ps -el | grep fdfs
• 启动nginx命令：/usr/local/nginx/sbin/nginx
• 停止命令： 停止tracker命令：/etc/init.d/fdfs_trackerd stop
• 关闭storage命令：/etc/init.d/fdfs_storaged stop
• 关闭nginx命令：/usr/local/nginx/sbin/nginx -s stop

使用Java客户端操作

classpath下建立文件fastdfs_client.conf

输入以下内容

tracker_server = 192.168.125.129:22122

总结

FastDFS的安装算是比较麻烦的 不过按照本篇 一步一步来 是绝对可以安装成功的 集群的安装就更麻烦了 个人暂时用不到 就不安装了
