跟踪服务器：
Tracker Server1 IP:  10.10.16.201 FASTDFS-TRACKER-01
Tracker Server2 IP:  10.10.16.202 FASTDFS-TRACKER-02

存储服务器：
Storage Server1 IP:  10.10.16.203 FASTDFS-STORAGE-01
Storage Server2 IP:  10.10.16.204 FASTDFS-STORAGE-02

集群中各操作系统环境设置：
(1)        fastdfs安装目录：/usr/local/fastdfs
[iyunv@FASTDFS-TRACKER-01 local]# mkdir /usr/local/fastdfs
[iyunv@FASTDFS-TRACKER-02 local]# mkdir /usr/local/fastdfs
[iyunv@FASTDFS-STORAGE-01 local]# mkdir /usr/local/fastdfs
[iyunv@FASTDFS-STORAGE-02 local]# mkdir /usr/local/fastdfs

(2)创建fastdfs用户组及fastdfs用户（四台机同时配置）:
[iyunv@xxx]# groupadd fastdfs
[iyunv@xxx]# useradd -g fastdfs fastdfs
[iyunv@xxx]# passwd fastdfs
## 设置fastdfs用户密码为gzzyzz.com （上生产前要改）

(3) 创建数据存储目录:
#创建tracker目录保存运行日志(Tracker服务器)
[fastdfs@FASTDFS-TRACKER-01 ~]$ mkdir -p /home/fastdfs/tracker
[fastdfs@FASTDFS-TRACKER-02 ~]$ mkdir -p /home/fastdfs/tracker
#创建Storage目录保存运行日志及其data数据（Storage服务器）
[fastdfs@FASTDFS-STORAGE-01 ~] $ mkdir -p /home/fastdfs/storage
[fastdfs@FASTDFS-STORAGE-02 ~] $ mkdir -p /home/fastdfs/storage

注：因为要源码编译安装软件，因而各系统要事先安装好:make cmake gcc gcc-c++
[iyunv@FASTDFS-TRACKER-01 yum.repos.d]# yum install make cmake gcc gcc-c++

1、        首先安装libevent（集群中所有服务器都执相同的安装）:
fastdfs在编译源程序时fastdfs内部调用libevent的处理机制,需要用到libevent一些依赖文件,否则编译fastdfs会出错。
# 卸载系统自带libevent,自带版本过低,要不然安装fastdfs会出错
[iyunv@FASTDFS-TRACKER-01 fastdfs]# rpm -qa|grep libevent
libevent-1.4.13-4.el6.x86_64
（由上可以系统自带了libevent-1.4.13-4.el6.x86_64）
卸载：
[iyunv@FASTDFS-TRACKER-01 fastdfs]# rpm -e --nodeps libevent-1.4.13-4.el6.x86_64

#下载安装libevent
进入/usr/local/src目录
# cd /usr/local/src/
[iyunv@FASTDFS-TRACKER-01 src]#
wget http://cloud.github.com/download ... .0.19-stable.tar.gz

[iyunv@FASTDFS-TRACKER-01 src]# tar -zxvf libevent-2.0.19-stable.tar.gz
[iyunv@FASTDFS-TRACKER-01 src]# cd libevent-2.0.19-stable
#make clean;
[iyunv@FASTDFS-TRACKER-01 libevent-2.0.19-stable]$ ./configure --prefix=/usr/local/libevent
[iyunv@FASTDFS-TRACKER-01 libevent-2.0.19-stable]# make
[iyunv@FASTDFS-TRACKER-01 libevent-2.0.19-stable]# make && make install
#为libevent创建软链接到/lib库下，64位系统对应/lib64
[iyunv@FASTDFS-TRACKER-01 libevent-2.0.19-stable]#
ln -s /usr/local/libevent/lib/libevent-2.0.so.5 /usr/lib/libevent-2.0.so.5
[iyunv@FASTDFS-TRACKER-01 libevent-2.0.19-stable]#
ln -s /usr/local/libevent/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5

2、        安装FastDFS（集群中所有服务器都执相同的安装）:
进入/usr/local/src目录
[iyunv@FASTDFS-TRACKER-01 src]#
wget https://fastdfs.googlecode.com/files/FastDFS_v4.06.tar.gz
[iyunv@FASTDFS-TRACKER-01 src]# tar -zxvf FastDFS_v4.06.tar.gz
[iyunv@FASTDFS-TRACKER-01 src]# cd FastDFS

#由于定义/usr/local/fastdfs为fastdfs安装目录,所以需要修改make.sh
[gw@register2 FastDFS]$ vi make.sh
# /etc/fdfs 全部替换为 /usr/local/fastdfs/conf
# TARGET_PREFIX=/usr/local 修改为 /usr/local/fastdfs
# TARGET_CONF_PATH=/etc/fdfs 修改为 /usr/local/fastdfs/conf
附件：

#安装
[iyunv@FASTDFS-TRACKER-01 FastDFS]$
./make.sh C_INCLUDE_PATH=/usr/local/libevent/include LIBRARY_PATH=/usr/local/libevent/lib
# 切换到超级管理员
[iyunv@FASTDFS-TRACKER-01 FastDFS]# ./make.sh install

注意：如果安装时提示找不到命令，请查看是不是没有装perl安装环境
wget  http://www.cpan.org/src/5.0/perl-5.18.2.tar.gz
tar -zxvf  perl-5.18.2.tar.gz
cd perl-5.18.2
./Configure
make
make install

3、        配置Tracker Server（10.10.16.201，10.10.16.202）:
进入/usr/local/fastdfs/conf
#修改tracker.conf配置
[iyunv@FASTDFS-TRACKER-01 conf]# vi /usr/local/fastdfs/conf/tracker.conf
绑定IP:
bind_addr=10.10.16.201 和 bind_addr=10.10.16.202

#设置日志目录
由base_path=/home/yuqing/fastdfs 改为 base_path=/home/fastdfs/tracker
store_group=group1
run_by_group= 改为 run_by_group=fastdfs
run_by_user= 改为 run_by_user=fastdfs
trunk_create_file_space_threshold = 20G
#开启自trunk_create_file_space_threshold定义server ID取代ip形式,方便内部网络服务器更换ip#**此方式要重点理解，4.0以后新特性
use_storage_id = true #使用server ID作为storage server标识
storage_ids_filename = storage_ids.conf  #<id> <group_name> <ip_or_hostname>
id_type_in_filename = id #文件名反解析中包含server ID,以前是ip

复制storage_ids.conf文件
[iyunv@FASTDFS-TRACKER-01 conf]#
cp /usr/local/src/FastDFS/conf/storage_ids.conf /usr/local/fastdfs/conf/
#编辑storage服务器ID与IP地址的对应关系
[iyunv@register1 conf]# vi /usr/local/fastdfs/conf/storage_ids.conf
# <id>  <group_name>  <ip_or_hostname>
100001  group1        10.10.16.203
100002  group1        10.10.16.204

防火墙打开8080和22122端口：
# vi /etc/sysconfig/iptables
增加：
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22122 -j ACCEPT
重启防火墙:
# /etc/init.d/iptables restart

自定义tracker服务启动、关闭、重启脚本：
# su fastdfs
切换回fastdfs用户后
$ cd /home/fastdfs/tracker/
(1)启动脚本：
[fastdfs@FASTDFS-TRACKER-01 tracker]$ vi start_tracker.sh
/usr/local/fastdfs/bin/fdfs_trackerd /usr/local/fastdfs/conf/tracker.conf

(2)关闭脚本（使用FastDFS自带的stop.sh脚本）：
[fastdfs@FASTDFS-TRACKER-01 tracker]$ vi stop_tracker.sh
/usr/local/fastdfs/bin/stop.sh /usr/local/fastdfs/bin/fdfs_trackerd /usr/local/fastdfs/conf/tracker.conf

(3)重启脚本（使用FastDFS自带的restart.sh脚本）：
[fastdfs@FASTDFS-TRACKER-01 tracker]$ vi restart_tracker.sh
/usr/local/fastdfs/bin/restart.sh /usr/local/fastdfs/bin/fdfs_trackerd /usr/local/fastdfs/conf/tracker.conf

注意：千万不要使用kill -9参数强杀进程，否则可能会导致binlog数据丢失的问题

给自定义脚本赋予可执行权限：
[fastdfs@FASTDFS-TRACKER-01 tracker]$ chmod +x *_tracker.sh

启动tracker服务：
[fastdfs@FASTDFS-TRACKER-01 tracker]$ ./start_tracker.sh
查看是否启用成功：
[fastdfs@FASTDFS-TRACKER-01 tracker]$ ps -ef | grep fastdfs
root     27253 26511  0 10:03 pts/0    00:00:00 su fastdfs
fastdfs  27254 27253  0 10:03 pts/0    00:00:00 bash
fastdfs  27580     1  0 10:25 ?        00:00:00 /usr/local/fastdfs/bin/fdfs_trackerd /usr/local/fastdfs/conf/tracker.conf
fastdfs  27588 27254  5 10:25 pts/0    00:00:00 ps -ef
fastdfs  27589 27254  0 10:25 pts/0    00:00:00 grep fastdfs
[fastdfs@FASTDFS-TRACKER-01 tracker]$
（首次正常启动后会在/home/fastdfs/tracker目录下会产生data目录和logs目录）
[2014-01-12 16:33:54] INFO - local_host_ip_count: 2,  127.0.0.1  10.10.16.201
[2014-01-12 16:34:11] INFO - file: tracker_service.c, line: 920, the tracker leader is 10.10.16.202:22122
停用tracker服务：
[fastdfs@FASTDFS-TRACKER-01 tracker]$ ./stop_tracker.sh

重启tracker服务：
[fastdfs@FASTDFS-TRACKER-01 tracker]$ ./restart_tracker.sh

4、        配置Storage Server(10.10.16.203、10.10.16.204，两台机执行相同的配置操作)：
# cd /usr/local/fastdfs/conf
# vi storage.conf
绑定IP分别为:
bind_addr=10.10.16.203 和 bind_addr=10.10.16.204

base_path=/home/yuqing/fastdfs 改为 base_path=/home/fastdfs/storage
store_path0=/home/yuqing/fastdfs 改为 store_path0=/home/fastdfs/storage
tracker_server=192.168.209.121:22122 改为
tracker_server=10.10.16.201:22122
tracker_server=10.10.16.202:22122
（这里我们配了两个跟踪器服务）
run_by_group= 改为 run_by_group=fastdfs
run_by_user= 改为 run_by_user=fastdfs
# 与Nginx端口相同
http.server_port=80

防火墙打开23000和8888端口：
# vi /etc/sysconfig/iptables
增加：
-A INPUT -m state --state NEW -m tcp -p tcp --dport 23000 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8888 -j ACCEPT
重启防火墙:
# /etc/init.d/iptables restart

自定义storage服务启动、关闭、重启脚本：
# su fastdfs
切换回fastdfs用户后
$ cd /home/fastdfs/storage/
(1)启动脚本：
[fastdfs@FASTDFS-STORAGE-01 storage]$ vi start_storage.sh
/usr/local/fastdfs/bin/fdfs_storaged /usr/local/fastdfs/conf/storage.conf

(2)关闭脚本（使用FastDFS自带的stop.sh脚本）：
[fastdfs@FASTDFS-STORAGE-01 storage]$ vi stop_tracker.sh
/usr/local/fastdfs/bin/stop.sh /usr/local/fastdfs/bin/fdfs_storaged /usr/local/fastdfs/conf/storage.conf

(3)重启脚本（使用FastDFS自带的restart.sh脚本）：
[fastdfs@FASTDFS-STORAGE-01 storage]$ vi restart_storage.sh
/usr/local/fastdfs/bin/restart.sh /usr/local/fastdfs/bin/fdfs_storaged /usr/local/fastdfs/conf/storage.conf

注意：千万不要使用kill -9参数强杀进程，否则可能会导致binlog数据丢失的问题

给自定义脚本赋予可执行权限：
[fastdfs@FASTDFS-STORAGE-01 storage]$ chmod +x *_storage.sh

启动Storage Server:
[fastdfs@FASTDFS-STORAGE-01 storage]$ ./start_storage.sh
data path: /home/fastdfs/storage/data, mkdir sub dir...
mkdir data path: 00 ...
mkdir data path: 01 ...
mkdir data path: 02 ...
mkdir data path: 03 ...
（首次成功启动会初始化数据存储目录）

重启storage服务：
[fastdfs@FASTDFS-STORAGE-01 storage]$ ./restart_storage.sh

停止storage服务：
[fastdfs@FASTDFS-STORAGE-01 storage]$ ./stop_storage.sh

Storage Server（10.10.16.203和10.10.16.204）安装Nginx:
#安装Nginx使用fastdfs用户
#创建nginx日志目录
# mkdir -p /home/fastdfs/nginx/logs
# chmod a+w /home/fastdfs/nginx/logs
# chown -R fastdfs:fastdfs /home/fastdfs/nginx/logs

安装nginx1.4.4:
# cd /usr/local/src
#下载 nginx
[iyunv@FASTDFS-STORAGE-01 src]#
wget http://nginx.org/download/nginx-1.4.4.tar.gz
解压：
# tar -zxvf nginx-1.4.4.tar.gz
# cd nginx-1.4.4

# ./configure --user=fastdfs --group=fastdfs --prefix=/usr/local/nginx --with-http_stub_status_module

如果产生如下错误提示：
checking for PCRE library ... not found
checking for PCRE library in /usr/local/ ... not found
checking for PCRE library in /usr/include/pcre/ ... not found
checking for PCRE library in /usr/pkg/ ... not found
checking for PCRE library in /opt/local/ ... not found

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

（大概意思是：HTTP重定向模块的安装需要PCRE库，网上搜了一下，是需要安装pcre-devel与openssl-devel）
# yum install pcre-devel openssl openssl-devel
（RHEL6.3 x64 桌面版中已自带以上包）

再重新执行：
# ./configure --user=fastdfs --group=fastdfs --prefix=/usr/local/nginx --with-http_stub_status_module

#--with-http_stub_status_module 用来监控nginx的当前状态

执行安装：# make && make install
安装fastdfs-nginx-module插件：
# cd /usr/local/src
# wget http://fastdfs.googlecode.com/fi ... module_v1.15.tar.gz
# tar -zxvf fastdfs-nginx-module_v1.15.tar.gz

#复制mod_fastdfs.conf到/usr/local/fastdfs/conf/目录下
# cp /usr/local/src/fastdfs-nginx-module/src/mod_fastdfs.conf /usr/local/fastdfs/conf/

上面编译时使用的动态链接库：
#启动nginx报错
#./nginx: error while loading shared libraries: libfastcommon.so: cannot open shared object file: No such file or directory
#解决办法 ---> 将/usr/local/fastdfs/lib 加入系统文件/etc/ld.so.conf中
# vi /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/local/fastdfs/lib

#更新库文件缓存ld.so.cache
# /sbin/ldconfig -v

编译fastdfs-nginx-module模块：
# 重新编译安装nginx
# cd /usr/local/src/nginx-1.4.4
# ./configure --add-module=/usr/local/src/fastdfs-nginx-module/src

# make && make install

修改mod_fastdfs.conf配置:
# vi /usr/local/fastdfs/conf/mod_fastdfs.conf

# connect timeout in seconds
# default value is 30s
connect_timeout=30

# the base path to store log files
base_path=/tmp

# if load FastDFS parameters from tracker server
# since V1.12
# default value is false
load_fdfs_parameters_from_tracker=true

# if use storage ID instead of IP address
# same as tracker.conf
# valid only when load_fdfs_parameters_from_tracker is false
# default value is false
# since V1.13
use_storage_id = true

# FastDFS tracker_server can ocur more than once, and tracker_server format is
#  "host:port", host can be hostname or ip address
# valid only when load_fdfs_parameters_from_tracker is true
tracker_server=10.10.16.201:22122
tracker_server=10.10.16.202:22122

# the port of the local storage server
# the default value is 23000
storage_server_port=23000

# the group name of the local storage server
group_name=group1

# if the url / uri including the group name
# set to false when uri like /M00/00/00/xxx
# set to true when uri like ${group_name}/M00/00/00/xxx, such as group1/M00/xxx
# default value is false
url_have_group_name = true

# path(disk or mount point) count, default value is 1
# must same as storage.conf
store_path_count=1

# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
# must same as storage.conf
store_path0=/home/fastdfs/storage

# set the log filename, such as /usr/local/apache2/logs/mod_fastdfs.log
# empty for output to stderr (apache and nginx error_log file)
log_filename=/home/fastdfs/nginx/logs/mod_fastdfs.log


注意, 下载时如发现老报404. 将nginx.conf第一行 usr nobody 修改为 user root 重新启动后解决.

给 storage 的存储目录做一个软连接
# ln -s /home/fastdfs/storage/data /home/fastdfs/storage/data/M00

访问路径带group名（storage对应有多个group的情况），如/group1/M00/00/00/xxx:
      location ~ /group([0-9])/M00 {
            ngx_fastdfs_module;
        }


nginx配置简洁版本:
# vi /usr/local/nginx/conf/nginx.conf
user root root;
worker_processes  2;
error_log  /home/fastdfs/nginx/logs/error.log  notice;
pid        /home/fastdfs/nginx/logs/nginx.pid;
worker_rlimit_nofile 5120;

events {
    use epoll;
    worker_connections  5120;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    tcp_nopush     on;
    keepalive_timeout  65;
    tcp_nodelay on;
    server {
        listen       80;
        server_name  localhost;
        #charset koi8-r;
        location ~/group([0-9])/M00 {
            #alias /home/fastdfs/storage/data;
            ngx_fastdfs_module;
        }
    }
}


#启动nginx：
# /usr/local/nginx/sbin/nginx

#重启nginx：
# /usr/local/nginx/sbin/nginx -s reload
