title: CentOS 7.2搭建FastDFS 分散式檔案系統，實現高可用叢集

分散式叢集搭建結構

雙Tracker
2組Group
輪詢儲存策略
Keepalived+Nginx高可用
Nginx快取
4個儲存節點

一、叢集規劃清單

1.安裝清單

軟體名稱	版本	百度雲盤存放名稱
FastDFS	5.11	fastdfs-5.11.zip
FastDFS-Nginx-module	無	fastdfs-nginx-module-master.zip
LibFastCommon	1.0.36	libfastcommon-1.0.36.zip
nginx	1.10.3	nginx-1.10.3.tar.gz
nginx-pure-cache	2.3	ngx_cache_purge-2.3.tar.gz

安裝所需檔案均上傳到百度雲盤，位置：FastDFS百度雲盤

2.叢集規劃

虛擬機器器	IP	說明
Keepalived+Nginx1[Master]	192.168.43.101	Nginx Server 01
Keeepalived+Nginx[Backup]	192.168.43.102	Nginx Server 02
VIP	192.168.43.150	虛擬漂移IP
Tracker01	192.168.43.70	Tracker01伺服器
Tracker02	192.168.43.71	Tracker02伺服器
Storage01	192.168.43.72	Storage01伺服器【group1】
Storage02	192.168.43.73	Storage02伺服器【group1】
Storage03	192.168.43.74	Storage03伺服器【group2】
Storage04	192.168.43.75	Storage04伺服器【group2】

整體架構圖如下圖所示：

二、叢集安裝

以下操作均在關閉所有節點防火牆進行的，請根據個人情況開啟相關埠或關閉防火牆

1.安裝LibFastCommon/FastDFS模組

執行節點 Tracker01、Tracker02、Storage01、Storage03、Storage04

[root@localhost fastDFS]# unzip libfastcommon-1.0.36.zip 
複製程式碼

解壓後目錄如下：

[root@localhost fastdfs-5.11]# ll
[root@localhost libfastcommon-1.0.36]# ll
總用量 32
drwxr-xr-x. 2 root root  117 4月   5 2017 doc

-rw-r--r--. 1 root root 2763 4月   5 2017 README
drwxr-xr-x. 3 root root 4096 1月  17 11:21 src
複製程式碼

安裝C編譯工具 gcc

[root@localhost fastdfs-5.11]# yum -y install gcc-c++
複製程式碼

安裝裝LibFastCommon

編譯libfastcommon軟體並安裝

[root@localhost fastdfs-5.11]# ./make.sh  && ./make.sh install
複製程式碼

為libcommon 建立軟連結到/usr/local/lib目錄下

[root@localhost fastdfs-5.11]# ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so
[root@localhost fastdfs-5.11]# ln -s /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so
[root@localhost fastdfs-5.11]# ln -s /usr/lib64/libfdfsclient.so /usr/local/lib/libfdfsclient.so
[root@localhost fastdfs-5.11]# ln -s /usr/lib64/libfdfsclient.so /usr/lib/libfdfsclient.so
複製程式碼

安裝FastDFS 解壓安裝包

[root@localhost fastDFS]# unzip fastdfs-5.11.zip 
複製程式碼

進入解壓目錄並進行編譯和安裝

[root@localhost fastDFS]# cd fastdfs-5.11/
[root@localhost fastdfs-5.11]# ./make.sh  && ./make.sh install
複製程式碼

安裝成功後，FastDFS會安裝在/etc/fdfs目錄下：

[root@localhost fastdfs-5.11]# ll /etc/fdfs/
總用量 76
-rw-r--r--. 1 root root   316 1月  17 11:47 client.conf

-rw-r--r--. 1 root root  7389 1月  17 11:25 tracker.conf.sample
複製程式碼

我們需要把這三個示例檔案複製一份，去掉.sample

[root@localhost fdfs]# cp client.conf.sample client.conf
[root@localhost fdfs]# cp storage.conf.sample storage.conf
[root@localhost fdfs]# cp tracker.conf.sample tracker.conf
複製程式碼

FastDFS安裝結束

2.安裝Tracker並實現節點資訊配置

執行節點 Tracker01、Tracker02

此目錄用於儲存tracker 的data和log

[root@localhost fdfs]# mkdir /opt/fastdfs_tracker
複製程式碼

配置tracker

配置 /etc/fdfs目錄下tracker.conf 主要實現以下5個配置內容：

1.disabled=false 
2.port=22122 #預設埠號 
3.base_path=/opt/fastdfs_tracker #我剛剛建立的目錄 
4.http.server_port=8080 #預設埠是8080
5.store_lookup=0  #採用輪詢策略進行儲存，0 輪詢 1：始終定向到某個group 2：負載進行儲存檔案
複製程式碼

完整tracker.conf 檔案資訊如下：

disabled=false

bind_addr= 0.0.0.0

port=22122

connect_timeout=30

network_timeout=60

base_path=/opt/fastdfs_tracker

max_connections=512

accept_threads=1

work_threads=4

min_buff_size = 8KB

max_buff_size = 128KB

http.server_port=8080

http.check_alive_interval=30

http.check_alive_type=tcp

http.check_alive_uri=/status.html
複製程式碼

修改儲存後建立軟引用

[root@localhost fdfs]# ln -s /usr/bin/fdfs_storaged /usr/local/bin
複製程式碼

啟動tracker，並加入開機啟動項

[root@localhost fdfs]# service fdfs_trackerd start
複製程式碼

將tracker加入開機啟動項

[root@localhost fdfs]# echo "service fdfs_trackerd start" |tee -a /etc/rc.d/rc.local
複製程式碼

3.安裝Storage模組並實現配置

執行節點 Storage01、Storage02、Storage03、Storage04

在儲存各節點建了兩個目錄fastdfs_storage_data,fastdfs_storage

[root@localhost opt]# mkdir fastdfs_storage
[root@localhost opt]# mkdir fastdfs_storage_data
[root@localhost opt]# ll
總用量 0
drwxr-xr-x. 4 root root 30 1月  17 11:45 fastdfs_storage

drwxr-xr-x. 4 root root 30 1月  17 11:35 fastdfs_tracker
複製程式碼

修改儲存節點目錄下/etc/fdfs/storage.conf配置資訊，具體如下：

disabled=false #啟用配置檔案  
group_name=group1 #組名（第一組為 group1， 第二組為 group2）  
port=23000 #storage 的埠號,同一個組的 storage 埠號必須相同  
base_path=/opt/fastdfs_storage #設定storage資料檔案和日誌目錄 
store_path0=/opt/fastdfs_storage_data #實際檔案儲存路徑  
store_path_count=1 #儲存路徑個數，需要和 store_path 個數匹配  
tracker_server=192.168.43.70:22122 #tracker 伺服器的 IP 地址和埠  
tracker_server=192.168.43.70:22122 #多個 tracker 直接新增多條配置  
http.server_port=8888 #設定 http 埠號

(2)通過 Tracker2 中的 Nginx 來訪問

6.構建Keepalive+Nginx 實現虛擬IP的代理

關於使用Keepalive+Nginx進行代理的環境安裝，請參考本人簡書此文：Keepalived+Nginx+Tomcat 實現高可用Web叢集本文不再做贅述說明

啟動Keepalvie+nginx Master主節點【192.168.43.101】
啟動Keepalvie+nginx BackUp備節點【192.168.43.102】
修改2個節點Nginx下目錄的nginx.conf的配置檔案資訊，新增如下內容
主要內容為2個Tracker加入到Keepalive+nginx代理當中

upstream fastdfs_tracker {  
   server 192.168.43.70:8000 weight=1 max_fails=2 fail_timeout=30s;  
   server 192.168.43.71:8000 weight=1 max_fails=2 fail_timeout=30s;  
}  
複製程式碼

第二處修改是添加了一個location並且匹配規則是路徑當中有fastdfs

location /fastdfs {  
           root html;  
           index index.html index.htm;  
           proxy_pass http://fastdfs_tracker/;  
           proxy_set_header Host $http_host;  
           proxy_set_header Cookie $http_cookie;  
           proxy_set_header X-Real-IP $remote_addr;  
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;  
           proxy_set_header X-Forwarded-Proto $scheme;  
           client_max_body_size 300m;  
        }  
複製程式碼

完整配置程式碼如下：

修改之後，重新啟動Keepalive+Nginx2臺主備節點。

[root@nginx1 conf]#  /usr/local/nginx/sbin/nginx -s reload  
複製程式碼

我們現在就用虛擬IP192.168.43.150來訪問我們剛才上傳的圖片，只是注意在位址列中要記得輸入fastdfs（這是我們nginx.conf檔案中location /fastdfs{}規則規定的）。如下圖所示，發現，我們通過虛擬IP便可以訪問我們上傳的圖片了。這樣的好處是，對使用者來說，只需要訪問這個虛擬IP就可以了，不用關心FastDFS叢集內部的轉發機制。

至此，分散式檔案系統就搭建完成了，在通過Java訪問時，只要在配置檔案配置所有的Tracker節點IP資訊就可以啦！

補充說明：

如果Tracker 服務、Storage服務、Nginx服務開機後沒有自啟動，請執行一下操作並進行重啟

[root@localhost ~]# chkconfig  --add fdfs_trackerd
[root@localhost ~]# chkconfig  --add fdfs_storaged
複製程式碼

編輯目錄下的/etc/rc.d/rc.local,內容如下：

#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local
/usr/local/nginx/sbin/nginx
複製程式碼

主要增加了Nginx的啟動，之後進行檔案生效，重新啟動系統

[root@localhost ~]# chmod  +x /etc/rc.d/rc.local
[root@localhost ~]# source /etc/rc.d/rc.local 
[root@localhost ~]# reboot
