搭建fastdfs文件服務器

1、安裝FastDFS環境

一、跟蹤服務器(Tracker Server)php

tracker1:192.168.2.134html

tracker2:192.168.2.135
二、存儲服務器(Storage Server)linux

storage1:192.168.2.136nginx

storage2:192.168.2.137c++

storage3:192.168.2.138git

storage4:192.168.2.139
三、操做系統:CentOS7
用戶:root
數據存儲目錄:/home/fastdfsgithub

我把全部的安裝包下載到/usr/local/softpackages/下,解壓到當前目錄vim

[root@tracker1 ~]# ls /usr/local/softpackages/
5e5f3566bbfa57418b5506aaefbe107a42c9fcb1.zip  fastdfs-5.05  fastdfs-nginx-module-master  libfastcommon-1.0.7  nginx-1.12.1  nginx-1.12.1.tar.gz  V1.0.7.tar.gz  V5.05.tar.gz

2、FastDFS基礎配置

一、下載安裝 libfastcommon

libfastcommon是從 FastDFS 和 FastDHT 中提取出來的公共 C 函數庫,基礎環境,安裝便可 。瀏覽器

① 下載libfastcommonbash

# wget https://github.com/happyfish100/libfastcommon/archive/V1.0.7.tar.gz

② 解壓

# tar -zxvf V1.0.7.tar.gz

# cd libfastcommon-1.0.7

絕對路徑

# cd /usr/local/softpackages/libfastcommon-1.0.7

受權

# chmod 755 *

③ 編譯、安裝

# ./make.sh

# ./make.sh install

能夠一條語句:

# ./make.sh && ./make.sh install

④ libfastcommon.so 安裝到了/usr/lib64/libfastcommon.so,可是FastDFS主程序設置的lib目錄是/usr/local/lib,因此須要建立軟連接。

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

二、下載安裝FastDFS

① 下載FastDFS

# wget https://github.com/happyfish100/fastdfs/archive/V5.05.tar.gz

② 解壓

# tar -zxvf V5.05.tar.gz

# cd fastdfs-5.05

絕對路徑

# cd /usr/local/softpackages/fastdfs-5.05

受權

# chmod 755 *

③ 編譯、安裝

# ./make.sh

# ./make.sh install

④ 默認安裝方式安裝後的相應文件與目錄
A、服務腳本:

/etc/init.d/fdfs_storaged
/etc/init.d/fdfs_tracker

B、配置文件(這三個是做者給的樣例配置文件) :

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

C、命令工具在 /usr/bin/ 目錄下:

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
stop.sh
restart.sh 

⑤ FastDFS 服務腳本設置的 bin 目錄是 /usr/local/bin, 但實際命令安裝在 /usr/bin/ 下

兩種方式:

  》 一是修改FastDFS 服務腳本中相應的命令路徑,也就是把 /etc/init.d/fdfs_storaged 和 /etc/init.d/fdfs_tracker 兩個腳本中的 /usr/local/bin 修改爲 /usr/bin。

     # vim fdfs_trackerd
    使用查找替換命令進統一修改:%s+/usr/local/bin+/usr/bin
    # vim fdfs_storaged
    使用查找替換命令進統一修改:%s+/usr/local/bin+/usr/bin

# vi /etc/init.d/fdfs_storaged

》 二是創建 /usr/bin 到 /usr/local/bin 的軟連接,我是用這種方式。

# ln -s /usr/bin/fdfs_trackerd   /usr/local/bin
# ln -s /usr/bin/fdfs_storaged   /usr/local/bin
# ln -s /usr/bin/stop.sh         /usr/local/bin
# ln -s /usr/bin/restart.sh      /usr/local/bin

3、配置FastDFS跟蹤器(Tracker)

配置文件詳細說明參考:FastDFS 配置文件詳解

① 進入 /etc/fdfs,複製 FastDFS 跟蹤器樣例配置文件 tracker.conf.sample,並重命名爲 tracker.conf。

# cd /etc/fdfs

# cp tracker.conf.sample tracker.conf

# vim tracker.conf

[root@tracker1 ~]# cd /etc/fdfs
[root@tracker1 fdfs]#
[root@tracker1 fdfs]# ls
client.conf.sample  storage.conf.sample  tracker.conf.sample
[root@tracker1 fdfs]#
[root@tracker1 fdfs]# cp tracker.conf.sample tracker.conf
[root@tracker1 fdfs]#

② 編輯tracker.conf ,標紅的須要修改下,其它的默認便可。

# vi tracker.conf

# 配置文件是否不生效,false 爲生效
disabled=false

# 提供服務的端口
port=22122

# Tracker 數據和日誌目錄地址(根目錄必須存在,子目錄會自動建立)
base_path=/home/fastdfs/tracker

# HTTP 服務端口
http.server_port=80

③ 建立tracker基礎數據目錄,即base_path對應的目錄

# mkdir -p /home/fastdfs/tracker

 ④ 防火牆中打開跟蹤端口(默認的22122)

# vim /etc/sysconfig/iptables

添加以下端口行:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22122 -j ACCEPT

重啓防火牆:
# service iptables restart

⑤ 啓動Tracker

初次成功啓動,會在 /home/fdfsdfs/tracker/ (配置的base_path)下建立 data、logs 兩個目錄。

注意:

啓動前先受權

# chmod 755 /etc/init.d/fdfs_trackerd

# chmod 755 -R /usr/local/bin/fdfs_trackerd

能夠用這種方式啓動

# /etc/init.d/fdfs_trackerd start

也能夠用這種方式啓動,前提是上面建立了軟連接,後面都用這種方式

# service fdfs_trackerd start

查看 FastDFS Tracker 是否已成功啓動 ,22122端口正在被監聽,則算是Tracker服務安裝成功。

data  logs

關閉Tracker命令:

# service fdfs_trackerd stop

⑥ 設置Tracker開機啓動

# chkconfig fdfs_trackerd on

或者:
# vim /etc/rc.d/rc.local
加入配置:
/etc/init.d/fdfs_trackerd start 

⑦ tracker server 目錄及文件結構

Tracker服務啓動成功後,會在base_path下建立data、logs兩個目錄。目錄結構以下:

${base_path}
  |__data
  |   |__storage_groups.dat:存儲分組信息
  |   |__storage_servers.dat:存儲服務器列表
  |__logs
  |   |__trackerd.log: tracker server 日誌文件 

4、配置FastDFS 存儲 (Storage)

① 進入 /etc/fdfs 目錄,複製 FastDFS 存儲器樣例配置文件 storage.conf.sample,並重命名爲 storage.conf

# cd /etc/fdfs
# cp storage.conf.sample storage.conf

② 編輯storage.conf

標紅的須要修改,其它的默認便可。

# vi storage.conf

# 配置文件是否不生效,false 爲生效
disabled=false 

# 指定此 storage server 所在 組(卷)
group_name=group1

# storage server 服務端口
port=23000

# 心跳間隔時間,單位爲秒 (這裏是指主動向 tracker server 發送心跳)
heart_beat_interval=30

# Storage 數據和日誌目錄地址(根目錄必須存在,子目錄會自動生成)
base_path=/home/fastdfs/storage

# 存放文件時 storage server 支持多個路徑。這裏配置存放文件的基路徑數目,一般只配一個目錄。
store_path_count=1


# 逐一配置 store_path_count 個路徑,索引號基於 0。
# 若是不配置 store_path0,那它就和 base_path 對應的路徑同樣。
store_path0=/home/fastdfs/file

# FastDFS 存儲文件時,採用了兩級目錄。這裏配置存放文件的目錄個數。 
# 若是本參數只爲 N(如: 256),那麼 storage server 在初次運行時,會在 store_path 下自動建立 N * N 個存放文件的子目錄。
subdir_count_per_path=256

# tracker_server 的列表 ,會主動鏈接 tracker_server
# 有多個 tracker server 時,每一個 tracker server 寫一行
tracker_server=192.168.2.134:22122
tracker_server=192.168.2.135:22122
# 容許系統同步的時間段 (默認是全天) 。通常用於避免高峯同步產生一些問題而設定。 sync_start_time=00:00 sync_end_time=23:59 # 訪問端口 http.server_port=80

③ 建立Storage基礎數據目錄,對應base_path目錄

# mkdir -p /home/fastdfs/storage

這是配置的store_path0路徑

# mkdir -p /home/fastdfs/file

④ 防火牆中打開存儲器端口(默認的 23000)

# vim /etc/sysconfig/iptables

添加以下端口行:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 23000 -j ACCEPT

重啓防火牆:
# service iptables restart

⑤ 啓動 Storage

啓動Storage前確保Tracker是啓動的。初次啓動成功,會在 /home/fastdfs/storage 目錄下建立 data、 logs 兩個目錄。

注意:

啓動前先受權

# chmod 755 /etc/init.d/fdfs_storaged
# chmod 755 /usr/local/bin/fdfs_storaged

能夠用這種方式啓動

# /etc/init.d/fdfs_storaged start

也能夠用這種方式,後面都用這種

# service fdfs_storaged start

[root@storage1 ~]# service fdfs_storaged start
env: /etc/init.d/fdfs_storaged: Permission denied
[root@storage1 ~]#

[root@storage1 ~]#

⑥ 設置 Storage 開機啓動

# chkconfig fdfs_storaged on

或者:
# vim /etc/rc.d/rc.local
加入配置:
/etc/init.d/fdfs_storaged start

⑦ Storage 目錄

同 Tracker,Storage 啓動成功後,在base_path 下建立了data、logs目錄,記錄着 Storage Server 的信息。

在 store_path0 目錄下,建立了N*N個子目錄:

# ls /home/fastdfs/file/data/

5、文件上傳測試

① 修改 Tracker 服務器中的客戶端配置文件

# cd /etc/fdfs
# cp client.conf.sample client.conf

修改以下配置便可,其它默認。

# Client 的數據和日誌目錄
base_path=/home/fastdfs/client

# Tracker端口
tracker_server=192.168.2.134:22122

建立client基礎數據目錄,對應base_path目錄

# mkdir -p /home/fastdfs/client

② 上傳測試

 在linux內部執行以下命令上傳test.jpg 圖片

# /usr/bin/fdfs_upload_file /etc/fdfs/client.conf test.jpg

[root@tracker1 ~]# /usr/bin/fdfs_upload_file /etc/fdfs/client.conf test.jpg
-bash: /usr/bin/fdfs_upload_file: Permission denied
[root@tracker1 ~]#
[root@tracker1 ~]# chmod 755 /usr/bin/fdfs_upload_file
[root@tracker1 ~]# /usr/bin/fdfs_upload_file /etc/fdfs/client.conf test.jpg
group1/M00/00/00/wKgCiFz1bm-ATQNlAACLwhA7j18254.jpg

上傳成功後返回文件ID號:group1/M00/00/00/wKgCiFz1bm-ATQNlAACLwhA7j18254.jpg

返回的文件ID由group、存儲目錄、兩級子目錄、fileid、文件後綴名(由客戶端指定,主要用於區分文件類型)拼接而成。

6、安裝Nginx

上面將文件上傳成功了,但咱們沒法下載。所以安裝Nginx做爲服務器以支持Http方式訪問文件。同時,後面安裝FastDFS的Nginx模塊也須要Nginx環境。

Nginx只須要安裝到StorageServer所在的服務器便可,用於訪問文件。

一、安裝nginx所需環境  

① gcc 安裝

# yum install gcc-c++ -y

 

② PCRE pcre-devel 安裝

# yum install -y pcre pcre-devel

③ zlib 安裝

# yum install -y zlib zlib-devel

 

④ OpenSSL 安裝

# yum install -y openssl openssl-devel

 

二、安裝Nginx

① 下載nginx

# wget -c https://nginx.org/download/nginx-1.12.1.tar.gz

② 解壓

# tar -zxvf nginx-1.12.1.tar.gz
# cd nginx-1.12.1

 

③ 使用默認配置

# ./configure

 

實例操做以下:

[root@storage1 softpackages]# chmod 755 -R nginx-1.12.1
[root@storage1 softpackages]#
[root@storage1 softpackages]# cd nginx-1.12.1
[root@storage1 nginx-1.12.1]#
[root@storage1 nginx-1.12.1]# pwd

[root@storage1 nginx-1.12.1]#

 

④ 編譯、安裝

# make
# make install

⑤ 啓動nginx

# cd /usr/local/nginx/sbin/
# ./nginx 

其它命令
# ./nginx -s stop
# ./nginx -s quit
# ./nginx -s reload

⑥ 設置開機啓動

 

# vim /etc/rc.local

添加一行:
/usr/local/nginx/sbin/nginx

# 設置執行權限
# chmod 755 rc.local

 

⑦ 查看nginx的版本及模塊

# /usr/local/nginx/sbin/nginx -V

[root@storage1 ~]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.12.1
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)
configure arguments:

 

⑧ 防火牆中打開Nginx端口(默認的 80) 

添加後就能在本機使用80端口訪問了。

# vim /etc/sysconfig/iptables

添加以下端口行:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

重啓防火牆:
# service iptables restart

 

三、訪問文件

簡單的測試訪問文件

① 修改nginx.conf

# vim /usr/local/nginx/conf/nginx.conf

添加以下行,將 /group1/M00 映射到 /home/fastdfs/file/data
location /group1/M00 {
    alias /home/fastdfs/file/data;
}

# 重啓nginx
# /usr/local/nginx/sbin/nginx -s reload

查看80端口是否監聽

# netstat -tunlp | grep 80

[root@storage1 sbin]# netstat -tunlp | grep 80
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      31104/nginx: master

② 在瀏覽器訪問以前上傳的圖片、成功。

http://192.168.2.136/group1/M00/00/00/wKgCiFz1bm-ATQNlAACLwhA7j18254.jpg

7、FastDFS 配置 Nginx 模塊

一、安裝配置Nginx模塊

① fastdfs-nginx-module 模塊說明

  FastDFS 經過 Tracker 服務器,將文件放在 Storage 服務器存儲, 可是同組存儲服務器之間須要進行文件複製, 有同步延遲的問題。

  假設 Tracker 服務器將文件上傳到了 192.168.2.136,上傳成功後文件 ID已經返回給客戶端。

  此時 FastDFS 存儲集羣機制會將這個文件同步到同組存儲 192.168.2.138,在文件尚未複製完成的狀況下,客戶端若是用這個文件 ID 在 192.168.2.138 上取文件,就會出現文件沒法訪問的錯誤。

  而 fastdfs-nginx-module 能夠重定向文件連接到源服務器取文件,避免客戶端因爲複製延遲致使的文件沒法訪問錯誤。

② 下載 fastdfs-nginx-module、解壓

# 這裏爲啥這麼長一串呢,由於最新版的master與當前nginx有些版本問題。
# wget https://github.com/happyfish100/fastdfs-nginx-module/archive/5e5f3566bbfa57418b5506aaefbe107a42c9fcb1.zip

# 解壓
# unzip 5e5f3566bbfa57418b5506aaefbe107a42c9fcb1.zip

# 重命名
# mv fastdfs-nginx-module-5e5f3566bbfa57418b5506aaefbe107a42c9fcb1  fastdfs-nginx-module-master

③ 配置Nginx

在nginx中添加模塊

# 先停掉nginx服務
# /usr/local/nginx/sbin/nginx -s stop

進入解壓包目錄
# cd /usr/local/softpackages/nginx-1.12.1

# 添加模塊
# ./configure --add-module=../fastdfs-nginx-module-master/src

從新編譯、安裝
# make && make install

④ 查看Nginx的模塊

# /usr/local/nginx/sbin/nginx -V

有下面這個就說明添加模塊成功

[root@storage1 nginx-1.12.1]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.12.1
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)
configure arguments: --add-module=../fastdfs-nginx-module-master/src
[root@storage1 nginx-1.12.1]#

⑤ 複製 fastdfs-nginx-module 源碼中的配置文件到/etc/fdfs 目錄, 並修改

[root@storage1 ~]# cd /usr/local/softpackages/fastdfs-nginx-module-master/src/
[root@storage1 src]#
[root@storage1 src]# cp mod_fastdfs.conf /etc/fdfs/

修改以下配置,其它默認

# vi /etc/fdfs/mod_fastdfs.conf

# 鏈接超時時間
connect_timeout=10

# Tracker Server
tracker_server=192.168.2.134:22122

# StorageServer 默認端口
storage_server_port=23000

# 若是文件ID的uri中包含/group**,則要設置爲true
url_have_group_name = true

# Storage 配置的store_path0路徑,必須和storage.conf中的一致
store_path0=/home/fastdfs/file

⑥ 複製 FastDFS 的部分配置文件到/etc/fdfs 目錄

[root@storage1 softpackages]# cd fastdfs-5.05/conf/
[root@storage1 conf]#
[root@storage1 conf]# pwd
/usr/local/softpackages/fastdfs-5.05/conf
[root@storage1 conf]#
[root@storage1 conf]# cp anti-steal.jpg http.conf mime.types /etc/fdfs/

⑦ 配置nginx,修改nginx.conf

# vim /usr/local/nginx/conf/nginx.conf

修改配置,其它的默認

在80端口下添加fastdfs-nginx模塊

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

注意:

  listen 80 端口值是要與 /etc/fdfs/storage.conf 中的 http.server_port=80 (前面改爲80了)相對應。若是改爲其它端口,則須要統一,同時在防火牆中打開該端口。

  location 的配置,若是有多個group則配置location ~/group([0-9])/M00 ,沒有則不用配group。

⑧ 在/home/fastdfs/file 文件存儲目錄下建立軟鏈接,將其連接到實際存放數據的目錄,這一步能夠省略

# ln -s /home/fastdfs/file/data/ /home/fastdfs/file/data/M00 

⑨ 啓動nginx

# /usr/local/nginx/sbin/nginx

打印處以下就算配置成功

[root@storage1 ~]# /usr/local/nginx/sbin/nginx
ngx_http_fastdfs_set pid=34082
[root@storage1 ~]#

⑩ 在地址欄訪問。

能下載文件就算安裝成功。注意和第三點中直接使用nginx路由訪問不一樣的是,這裏配置 fastdfs-nginx-module 模塊,能夠重定向文件連接到源服務器取文件。
