分布式集群搭建结构

双Tracker
2组Group
轮询存储策略
Keepalived+Nginx高可用
Nginx缓存
4个存储节点

一、集群规划清单

1.安装清单

软件名称	版本	百度云盘存放名称
FastDFS	5.11	fastdfs-5.11.zip
FastDFS-Nginx-module	无	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

安装所需文件均上传到百度云盘，位置：FastDFS百度云盘

2.集群规划

虚拟机	IP	说明
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	虚拟漂移IP
Tracker01	192.168.43.70	Tracker01服务器
Tracker02	192.168.43.71	Tracker02服务器
Storage01	192.168.43.72	Storage01服务器【group1】

Storage03	192.168.43.74	Storage03服务器【group2】
Storage04	192.168.43.75	Storage04服务器【group2】

整体架构图如下图所示：

二、集群安装

以下操作均在关闭所有节点防火墙进行的，请根据个人情况开启相关端口或关闭防火墙

1.安装LibFastCommon/FastDFS模块

执行节点 Tracker01、Tracker02、Storage01、Storage03、Storage04

[root@localhost fastDFS]# unzip libfastcommon-1.0.36.zip

解压后目录如下：

[root@localhost fastdfs-5.11]# ll
[root@localhost libfastcommon-1.0.36]# ll
总用量 32
drwxr-xr-x. 2 root root  117 4月   5 2017 doc
-rw-r--r--. 1 root root 8005 4月   5 2017 HISTORY
-rw-r--r--. 1 root root  566 4月   5 2017 INSTALL
-rw-r--r--. 1 root root 1606 4月   5 2017 libfastcommon.spec
-rwxr-xr-x. 1 root root 3099 4月   5 2017 make.sh
drwxr-xr-x. 2 root root  191 4月   5 2017 php-fastcommon
-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

安装C编译工具 gcc

[root@localhost fastdfs-5.11]# yum -y install gcc-c++

安装装LibFastCommon

编译libfastcommon软件并安装

[root@localhost fastdfs-5.11]# ./make.sh  && ./make.sh install

为libcommon 创建软链接到/usr/local/lib目录下

[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

安装FastDFS 解压安装包

[root@localhost fastDFS]# unzip fastdfs-5.11.zip

进入解压目录并进行编译和安装

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

安装成功后，FastDFS会安装在/etc/fdfs目录下：

[root@localhost fastdfs-5.11]# ll /etc/fdfs/
总用量 76
-rw-r--r--. 1 root root   316 1月  17 11:47 client.conf
-rw-r--r--. 1 root root  1461 1月  17 11:25 client.conf.sample
-rw-r--r--. 1 root root   955 1月  17 13:20 http.conf
-rw-r--r--. 1 root root 31172 1月  17 13:21 mime.types
-rw-r--r--. 1 root root  3716 1月  17 12:57 mod_fastdfs.conf
-rw-r--r--. 1 root root  1278 1月  17 11:40 storage.conf
-rw-r--r--. 1 root root  7927 1月  17 11:25 storage.conf.sample
-rw-r--r--. 1 root root   105 1月  17 11:25 storage_ids.conf.sample
-rw-r--r--. 1 root root  1356 1月  17 11:34 tracker.conf
-rw-r--r--. 1 root root  7389 1月  17 11:25 tracker.conf.sample

我们需要把这三个示例文件复制一份，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

FastDFS安装结束

2.安装Tracker并实现节点信息配置

执行节点 Tracker01、Tracker02

此目录用于保存tracker 的data和log

[root@localhost fdfs]# mkdir /opt/fastdfs_tracker

配置tracker

配置 /etc/fdfs目录下tracker.conf 主要实现以下5个配置内容：

1.disabled=false 
2.port=22122 #默认端口号 
3.base_path=/opt/fastdfs_tracker #我刚刚创建的目录 
4.http.server_port=8080 #默认端口是8080
5.store_lookup=0  #采用轮询策略进行存储，0 轮询 1：始终定向到某个group 2：负载进行存储文件

完整tracker.conf 文件信息如下：

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

store_lookup=0

store_group=group2

store_server=0

store_path=0

download_server=0

reserved_storage_space = 10%

log_level=info

run_by_group=

run_by_user=

allow_hosts=*

sync_log_buff_interval = 10

check_active_interval = 120

thread_stack_size = 64KB

storage_ip_changed_auto_adjust = true

storage_sync_file_max_delay = 86400

storage_sync_file_max_time = 300

use_trunk_file = false 

slot_min_size = 256

slot_max_size = 16MB

trunk_file_size = 64MB

trunk_create_file_advance = false

trunk_create_file_time_base = 02:00

trunk_create_file_interval = 86400

trunk_create_file_space_threshold = 20G

trunk_init_check_occupying = false

trunk_init_reload_from_binlog = false

trunk_compress_binlog_min_interval = 0

use_storage_id = false

storage_ids_filename = storage_ids.conf

id_type_in_filename = ip

store_slave_file_use_link = false

rotate_error_log = false

error_log_rotate_time=00:00

rotate_error_log_size = 0

log_file_keep_days = 0

use_connection_pool = false

connection_pool_max_idle_time = 3600

http.server_port=8080

http.check_alive_interval=30

http.check_alive_type=tcp

http.check_alive_uri=/status.html

修改保存后创建软引用

[root@localhost fdfs]# ln -s /usr/bin/fdfs_storaged /usr/local/bin

启动tracker，并加入开机启动项

[root@localhost fdfs]# service fdfs_trackerd start

将tracker加入开机启动项

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

3.安装Storage模块并实现配置

执行节点 Storage01、Storage02、Storage03、Storage04

在存储各节点建了两个目录fastdfs_storage_data,fastdfs_storage

[root@localhost opt]# mkdir fastdfs_storage
[root@localhost opt]# mkdir fastdfs_storage_data
[root@localhost opt]# ll
总用量 0
drwxr-xr-x. 4 root root 30 1月  17 11:45 fastdfs_storage
drwxr-xr-x. 3 root root 18 1月  17 11:45 fastdfs_storage_data
drwxr-xr-x. 4 root root 30 1月  17 11:35 fastdfs_tracker

修改存储节点目录下/etc/fdfs/storage.conf配置信息，具体如下：

disabled=false #启用配置文件  
group_name=group1 #组名（第一组为 group1， 第二组为 group2）  
port=23000 #storage 的端口号,同一个组的 storage 端口号必须相同  
base_path=/opt/fastdfs_storage #设置storage数据文件和日志目录 
store_path0=/opt/fastdfs_storage_data #实际文件存储路径  
store_path_count=1 #存储路径个数，需要和 store_path 个数匹配  
tracker_server=192.168.43.70:22122 #tracker 服务器的 IP 地址和端口  
tracker_server=192.168.43.70:22122 #多个 tracker 直接添加多条配置  
http.server_port=8888 #设置 http 端口号

完整配置信息如下：

disabled=false
group_name=group1
bind_addr=
client_bind=true
port=23000
connect_timeout=30
network_timeout=60
heart_beat_interval=30
stat_report_interval=60
base_path=/opt/fastdfs_storage
max_connections=256
buff_size = 256KB
accept_threads=1
work_threads=4
disk_rw_separated = true
disk_reader_threads = 1
disk_writer_threads = 1
sync_wait_msec=50
sync_interval=0
sync_start_time=00:00

发现此时192.168.43.71作为Tracker的Leader。

设置Storage开机自启动

[root@localhost fdfs]#  echo "service fdfs_storaged start" |tee -a /etc/rc.d/rc.local

安装fastdfs-nginx-module、Nginx模块

安装Nginx模块所需的依赖环境

[root@localhost fdfs]# yum -y install pcre pcre-devel  
[root@localhost fdfs]# yum -y install zlib zlib-devel  
[root@localhost fdfs]# yum -y install openssl openssl-devel

解压nginx和fastdfs-nginx-module

[root@localhost fdfs]# tar -zxvf nginx-1.10.3.tar.gz
[root@localhost fdfs]# unzip fastdfs-nginx-module-master.zip

进入Nginx解压目录进行编译安装

[root@localhost nginx-1.10.3]# ./configure --prefix=/usr/local/nginx --add-module=/home/zhangyongliang/apps/fastdfs-nginx-module-master/src #解压后fastdfs-nginx-module所在的位置

安装成功后，nginx会安装在/usr/local/nginx,安装后查看

安装成功后，nginx尚未运行时，nginx文件夹没有临时文件夹，例如fastcgi_temp这些文件。
复制 fastdfs-nginx-module 源码中的配置文件到/etc/fdfs 目录，并修改

[root@localhost src]# cp /usr/local/src/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/  
[root@localhost src]# vi /etc/fdfs/mod_fastdfs.conf

(1)第1组 Storage 的 mod_fastdfs.conf 配置如下：

复制 FastDFS 安装目录的部分配置文件到/etc/fdfs 目录

[root@localhost conf]# pwd
/home/zhangyongliang/apps/fastdfs-5.11/conf
[root@localhost conf]# cp http.conf  mime.types  /etc/fdfs/

创建M00至storage存储目录的符号连接：

ln  -s  /opt/fastdfs_storage_data/data/ /opt/fastdfs_storage_data/data/M00

配置 Nginx，简洁版 nginx 配置样例

# vi /usr/local/nginx/conf/nginx.conf  
user root;  
worker_processes 1;  
events {  
    worker_connections 1024;  
}  
http {  
    include mime.types;  
    default_type application/octet-stream;  
    sendfile on;  
    keepalive_timeout 65;  
    server {  
        listen 8888;  
        server_name localhost;  
        location ~/group([0-9])/M00 {  
            #alias /fastdfs/storage/data;  
            ngx_fastdfs_module;  
        }  
        error_page 500 502 503 504 /50x.html;  
        location = /50x.html {  
            root html;  
        }  
    }  
}

注意、说明：
8888 端口值是要与/etc/fdfs/storage.conf 中的 http.server_port=8888 相对应，因为 http.server_port 默认为 8888,如果想改成 80，则要对应修改过来。
重新启动各节点的Nginx服务

[root@localhost conf]#/usr/local/nginx/sbin/nginx -s reload

4.文件上传测试

执行节点Tracker01、Tracker02
修改 Tracker 服务器中的客户端配置文件

# vi /etc/fdfs/client.conf  
base_path=/fastdfs/tracker  
tracker_server=192.168.43.70:22122  
tracker_server=192.168.43.71:22122

执行如下文件上传命令

[root@localhost zhangyongliang]# fdfs_upload_file /etc/fdfs/client.conf P71022-205803.jpg 
group1/M00/00/00/wKgrSFpjC26AH1g2AAvUQrxXbkA557.jpg
[root@localhost zhangyongliang]# fdfs_upload_file /etc/fdfs/client.conf P71022-205803.jpg 
group2/M00/00/00/wKgrSlpjC3aAARrXAAvUQrxXbkA048.jpg

进行2次上传后，发现文件被均衡分到2个group。

5.Tracker安装Nginx、 ngx_cache_purge 模块

安装编译 Nginx 所需的依赖包

[root@localhost zhangyongliang]# yum install gcc gcc-c++ make automake autoconf libtool pcre pcre-devel zlib zlib-devel openssl openssl-devel

解压Nginx和ngx_cache_pure模块

[root@localhost apps]# tar ngx_cache_purge-2.3.tar.gz
[root@localhost apps]# tar nginx-1.10.3.tar.gz

编译安装 Nginx（添加 ngx_cache_purge 模块）

[root@localhost apps]# cd nginx-1.13.0  
[root@localhost nginx-1.13.0# ./configure --prefix=/usr/local/nginx --add-module=/usr/local/src/ngx_cache_purge-2.3  
[root@localhost nginx-1.13.0]# make && make install

配置 Nginx，设置负载均衡以及缓存

6.构建Keepalive+Nginx 实现虚拟IP的代理

关于使用Keepalive+Nginx进行代理的环境安装，请参考本人简书此文：Keepalived+Nginx+Tomcat 实现高可用Web集群本文不再做赘述说明

启动Keepalvie+nginx Master主节点【192.168.43.101】
启动Keepalvie+nginx BackUp备节点【192.168.43.102】
修改2个节点Nginx下目录的nginx.conf的配置文件信息，添加如下内容
主要内容为2个Tracker加入到Keepalive+nginx代理当中

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;  
}

第二处修改是添加了一个location并且匹配规则是路径当中有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;  
        }

完整配置代码如下：


#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

    worker_connections  1024;
}

    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;
	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;  
    }

        location / {

            root   html;
        }
		location /fastdfs {  
           root html;  
           index index.html index.htm;  
           proxy_pass http://fastdfs_tracker/;

        }

        #
        #location ~ \.php$ {

        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server

    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

修改之后，重新启动Keepalive+Nginx2台主备节点。

[root@nginx1 conf]#  /usr/local/nginx/sbin/nginx -s reload

我们现在就用虚拟IP192.168.43.150来访问我们刚才上传的图片，只是注意在地址栏中要记得输入fastdfs（这是我们nginx.conf文件中location /fastdfs{}规则规定的）。如下图所示，发现，我们通过虚拟IP便可以访问我们上传的图片了。这样的好处是，对用户来说，只需要访问这个虚拟IP就可以了，不用关心FastDFS集群内部的转发机制。

至此，分布式文件系统就搭建完成了，在通过Java访问时，只要在配置文件配置所有的Tracker节点IP信息就可以啦！

补充说明：

如果Tracker 服务、Storage服务、Nginx服务开机后没有自启动，请执行一下操作并进行重启

[root@localhost ~]# chkconfig  --add fdfs_trackerd
[root@localhost ~]# chkconfig  --add fdfs_storaged

编辑目录下的/etc/rc.d/rc.local,内容如下：

#!/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

主要增加了Nginx的启动，之后进行文件生效，重新启动系统

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