FastDFS之文件服务器集群部署详解

[日期:2017-01-23] 来源:Linux社区  作者:Linux [字体: ]

FastDFS是一个开源的轻量级分布式文件系统,由跟踪服务器(tracker server)、存储服务器(storage server)和客户端(client)三个部分组成,主要解决了海量数据存储问题,特别适合以中小文件(建议范围:4KB < file_size <500MB)为载体的在线服务。在生成环境FastDFS一般都是用集群配置,以提高FastDFS的可用性,并发能力。

部署架构:

FastDFS之文件服务器集群部署详解

环境IP地址(关闭所有环境的防火墙):
Tracker 192.168.18.178
Group 1:
  S1:192.168.110.71
  S2:192.168.110.91

Group 2:
  S3:192.168.100.90
  S4:192.168.100.194
注:Tracker可以部署多台,提供负载,这里资源有限,就部署一台。
由于需要安装nginx,每台机器都安装依赖:
yum -y install  zlib pcre pcre-devel zlib-devel

所用的安装软件到Linux公社资源站下载:

一、安装tracker
1.安装依赖libfastcommon
unzip libfastcommon-master.zip

cd libfastcommon

./make.sh
./make.sh  install

2.安装FastDFS
unzip fastdfs.zip

cd fastdfs

./make.sh

./make.sh install

默认安装目录:/usr/bin
将原安装文件夹下的配置文件复制到/etc/fdfs目下:cp ./conf/*  /etc/fdfs/
3.配置
编辑配置文件目录下的tracker.conf
一般只需改动以下几个参数即可:
disabled=false            #启用配置文件
port=22122                #设置tracker的端口号
base_path=/home/fastdfs  #设置tracker的数据文件和日志目录(需预先创建)
http.server_port=8080    #设置http端口号
4.启动
/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start

二、安装tracker代理nginx
在tracker上安装的nginx主要为了提供http访问的反向代理、负载均衡以及缓存服务。
1.安装nginx
tar -zxvf nginx-1.8.0.tar.gz
tar -zxvf ngx_cache_purge-2.3.tar.gz
cd nginx-1.8.0
./configure --prefix=/usr/local/nginx --add-module=/root/ngx_cache_purge-2.3

make
make install

如果提示错误,可能缺少依赖的软件包,需先安装依赖包,再次运行./configure
nginx以及nginx cache purge插件模块安装完成,安装目录/usr/local/nginx

2.配置nginx
user  root; 
worker_processes  1; 
   
#error_log  logs/error.log; 
#error_log  logs/error.log  notice; 
error_log  logs/error.log  info; 
   
#pid        logs/nginx.pid; 
   
   
events { 
    worker_connections  1024; 

   
   
http { 
    include      mime.types; 
    default_type  application/octet-stream; 
    #设置缓存参数 
    server_names_hash_bucket_size 128; 
    client_header_buffer_size 32k; 
    large_client_header_buffers 4 32k; 
    client_max_body_size 300m; 
    sendfile        on; 
    tcp_nopush    on; 
    proxy_redirect off; 
    proxy_set_header Host $http_host; 
    proxy_set_header X-Real-IP $remote_addr; 
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
    proxy_connect_timeout 90; 
    proxy_send_timeout 90; 
    proxy_read_timeout 90; 
    proxy_buffer_size 16k; 
    proxy_buffers 4 64k; 
    proxy_busy_buffers_size 128k; 
    proxy_temp_file_write_size 128k; 
    #设置缓存存储路径、存储方式、分配内存大小、磁盘最大空间、缓存期限 
    proxy_cache_path /var/cache/nginx/proxy_cache levels=1:2 keys_zone=http-cache:500m max_size=10g inactive=30d; 
       
    proxy_temp_path /var/cache/nginx/proxy_cache/tmp; 
   
    keepalive_timeout  65; 
   
    #设置group服务器 
    upstream fdfs_group1 { 
        server 192.168.110.71:8090 weight=1 max_fails=2 fail_timeout=30s; 
        server 192.168.110.91:8090 weight=1 max_fails=2 fail_timeout=30s; 
    } 
    upstream fdfs_group2 { 
        server 192.168.100.90:8090 weight=1 max_fails=2 fail_timeout=30s; 
        server 192.168.100.194:8090 weight=1 max_fails=2 fail_timeout=30s; 
    } 
   
    server { 
        listen      80; 
        server_name  localhost; 
        charset utf-8; 
        #access_log  /usr/local/nginx/logs/localhost.access.log  main; 
   
        location /group1/M00 { 
                proxy_next_upstream http_502 http_504 error timeout invalid_header; 
                proxy_cache http-cache; 
                proxy_cache_valid  200 304 12h; 
                proxy_cache_key $uri$is_args$args; 
                proxy_pass http://fdfs_group1
                expires 30d; 
        } 
        location /group2/M00 { 
                proxy_next_upstream http_502 http_504 error timeout invalid_header; 
                proxy_cache http-cache; 
                proxy_cache_valid  200 304 12h; 
                proxy_cache_key $uri$is_args$args; 
                proxy_pass http://fdfs_group2
                expires 30d; 
        } 
        #设置清除缓存的访问权限 
        location ~ /purge(/.*) { 
                allow 127.0.0.1; 
                allow 172.16.1.0/24; 
                deny all; 
                proxy_cache_purge http-cache  $1$is_args$args; 
        } 
    } 
   
}

创建缓存目录:/var/cache/nginx/proxy_cache/tmp
3.启动
/usr/local/nginx/sbin/nginx

三、安装storage
1.安装
参考安装tracker前2步骤。
2.配置
编辑配置文件目录下的storage.conf


只需改动以下几个参数即可:
disabled=false    #启用配置文件
group_name=group1 #组名,根据实际情况修改
port=23000 #设置storage的端口号
base_path=/home/fastdfs #设置storage的日志目录(需预先创建)
store_path_count=1 #存储路径个数,需要和store_path个数匹配
store_path0=/home/fastdfs#存储路径
tracker_server=192.168.18.178:22122#tracker服务器的IP地址和端口号
http.server_port=8080  #设置http端口号

创建目录mkdir /home/fastdfs
3.运行
/usr/bin/fdfs_storaged /etc/fdfs/storage.conf start

另外:
分别在其他机器上全部安装storage并确认运行正常。注意配置文件中group名参数需要根据实际情况调整:
group1:192.168.110.71,192.168.110.91
group2:192.168.100.90,192.168.100.194
另外每个group中所有storage的端口号必须一致。

四、在storage上安装nginx
在storage上安装的nginx主要为了提供http的访问服务,同时解决group中storage服务器的同步延迟问题。
1.解压fastdfs-nginx-module插件
unzip  fastdfs-nginx-module.zip
2.安装nginx
tar -zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0
./configure --prefix=/usr/local/nginx --add-module=../fastdfs-nginx-module/src
make
make install
安装目录:/usr/local/nginx
若安装报错:[emerg] 13513#0: eventfd() failed (38: Function not implemented)
原因是:编译时带了--with-file-aio模块,这个要Linux 2.6.22以后内核才支持.服务器是2.6.18。也可以下载低版本的nginx版本
3.配置
1)配置FastDFS的nginx插件
将FastDFS的nginx插件模块的配置文件copy到FastDFS配置文件目录
fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/
编辑/etc/fdfs配置文件目录下的mod_fastdfs.conf,设置storage信息并保存。
一般只需改动以下几个参数即可:
base_path=/home/fastdfs #保存日志目录
tracker_server=192.168.18.178:22122 #tracker服务器的IP地址以及端口号
storage_server_port=23000#storage服务器的端口号
group_name=group1#当前服务器的group名
url_have_group_name = true        #文件url中是否有group名
store_path_count=1                #存储路径个数,需要和store_path个数匹配
store_path0=/home/fastdfs        #存储路径
http.need_find_content_type=true#从文件扩展名查找文件类型(nginx时为true)
group_count = 2                  #设置组的个数
在末尾增加2个组的具体信息:
[group1]
group_name=group1
storage_server_port=23000
store_path_count=1
store_path0=/home/fastdfs

[group2]
group_name=group2
storage_server_port=23000
store_path_count=1
store_path0=/home/fastdfs
建立M00至存储目录的符号连接:
ln -s /home/fastdfs/data /home/fastdfs/data/M00
2)配置nginx
vi nginx.conf
user root;


location ~/group[1-3]/M00 {
    root /home/fastdfs/data;
    ngx_fastdfs_module;
}
4.启动
/usr/local/nginx/sbin/nginx

另外:
分别在其他机器storage上全部安装nginx并确认运行正常。注意配置文件中group名参数需要根据实际情况调整:
group1:192.168.110.71,192.168.110.91
group2:192.168.100.90,192.168.100.194
另外nginx的端口号8090。

至此所有配置完毕。

五、测试
配置/etc/fdfs/client.conf
base_path=/home/fastdfs #日志存放路径

tracker_server=192.168.18.43:22122 #tracker服务器IP地址和端口号

http.tracker_server_port=8080  #tracker服务器的http端口号

通过fdfs_upload_file上传一个文件到FastDFS,程序会自动返回文件的URL,
#fdfs_upload_file /etc/fdfs/client.conf 40-15052PZK5.jpg
group1/M00/00/00/wKhuR1Vmh_2ADmdfAAF1dmVtk4w934.jpg
然后使用浏览器访问,访问正常
http://192.168.18.43/group1/M00/00/00/wKhuR1Vmh_2ADmdfAAF1dmVtk4w934.jpg

注:可以使用fdfs_monitor查看tracker和所有group的运行情况
# fdfs_monitor /etc/fdfs/client.conf
