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


[root@FASTDFS-TRACKER-01 local]# mkdir /usr/local/fastdfs


[root@FASTDFS-TRACKER-02 local]# mkdir /usr/local/fastdfs


[root@FASTDFS-STORAGE-01 local]# mkdir /usr/local/fastdfs


[root@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):


[root@xxx]# groupadd fastdfs


[root@xxx]# useradd -g fastdfs fastdfs


[root@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++


[root@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


[root@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:


[root@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/


[root@FASTDFS-TRACKER-01 src]#


wget http://cloud.github.com/downloads/libevent/libevent/libevent-2.0.19-stable.tar.gz

[root@FASTDFS-TRACKER-01 src]# tar -zxvf libevent-2.0.19-stable.tar.gz


[root@FASTDFS-TRACKER-01 src]# cd libevent-2.0.19-stable


#make clean;


[root@FASTDFS-TRACKER-01 libevent-2.0.19-stable]$ ./configure --prefix=/usr/local/libevent


[root@FASTDFS-TRACKER-01 libevent-2.0.19-stable]# make


[root@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


[root@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


[root@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


[root@FASTDFS-TRACKER-01 src]#


wget https://fastdfs.googlecode.com/files/FastDFS_v4.06.tar.gz


[root@FASTDFS-TRACKER-01 src]# tar -zxvf FastDFS_v4.06.tar.gz


[root@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


[root@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


[root@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


[root@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_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


[root@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


[root@register1 conf]# vi /usr/local/fastdfs/conf/storage_ids.conf


#


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


[root@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= 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/files/fastdfs-nginx-module_v1.15.tar.gz


# tar -zxvf fastdfs-nginx-module_v1.15.tar.gz

#修改插件配置文件


# vi /usr/local/src/fastdfs-nginx-module/src/config


ngx_addon_name=ngx_http_fastdfs_module


HTTP_MODULES="$HTTP_MODULES ngx_http_fastdfs_module"


NGX_ADDON_SRCS="$NGX_ADDON_SRCS $ngx_addon_dir/ngx_http_fastdfs_module.c"


CORE_INCS="$CORE_INCS /usr/local/fastdfs/include/fastdfs /usr/local/fastdfs/include/fastcommon/"


CORE_LIBS="$CORE_LIBS -L/usr/local/fastdfs/lib -lfastcommon -lfdfsclient"


CFLAGS="$CFLAGS -D_FILE_OFFSET_BITS=64 -DFDFS_OUTPUT_CHUNK_SIZE='256*1024' -DFDFS_MOD_CONF_FILENAME='/"/usr/local/fastdfs/conf/mod_fastdfs.conf/"'"

#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
