FastDFS 双tracker负载均衡 及多组存储配置

admin • • C/C++ • 阅读 140

应用场景: 三台服务器分别做三组存储，并且需要两台tracker地址做主备关系，当一台down机后需要另外一台可以提供正常的访问连接

注:此处不考虑存储数据安全性，如果需要保障数据不丢失，可以分别每台存储配置两组group(相同group之间数据会自动备份) ，三台服务器group分别为:

第一台服务器:group1 group2

第二台服务器:group1 group3

第三台服务器:group2 group3

需求图如下:

FastDFS 双tracker负载均衡 及多组存储配置

一: 为三台服务器分别部署FASTDFS + Nginx-fastdfs模块

  1. 安装所需依赖：
1 1. 安装libfastcommon
 2 cd /opt
 3 yum install git xz gcc g++ gcc-c++ autoconf automake make unzip  -y
 4 git clone https://github.com/happyfish100/libfastcommon.git
 5 cd libfastcommon/
 6 ./make.sh
 7 ./make.sh install
 8 
 9 #设置环境变量或创建软链接
10 export LD_LIBRARY_PATH=/usr/lib64/
11 ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so
12 
13 2.  安装libevent
14 cd /opt
15 wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
16 tar zxvf libevent-2.0.21-stable.tar.gz
17 cd libevent-2.0.21-stable
18 ./configure --prefix=/usr/local/
19 make clean
20 make && make install
21 ls –al /usr/lib | grep libevent(或ls –al /usr/local/lib | grep libevent)
22 #如果有返回结果则安装正常
23 
24 ln -s /usr/local/lib/libevent-2.0.so.5 /usr/lib/libevent-2.0.so.5
25 ln -s /usr/local/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5
  1. 安装配置FastDFS
1 1.下载安装fastdfs
 2 https://sourceforge.net/projects/fastdfs/files/?source=navbar（该网址下载所需版本FastDFS 此处使用4.0.6为例）
 3 cd /opt
 4 tar -zxvf FastDFS_4.06.tar.gz
 5 cd FastDFS
 6 ./make.sh
 7 ./make.sh install
 8 
 9 2. 创建文件存放路径
10 mkdir -p /home/fastdfs/tracker   #创建tracker文件存放路径
11 mkdir -p /home/fastdfs/storage    #创建storage 文件存放路径
12 mkdir -p /home/fastdfs/client    #创建client 文件存放路径
13 
14 cd /etc/fdfs/    #查看目录下文件是否齐全，应该有client.conf http.conf mime.types     storage.conf tracker.conf  5个文件，如果没有，libevent 安装有问题
15 
16 3. 修改配置文件（172.18.4.217-218 由于每台均作为tracker 所以需要全部配置，而172.18.4.219只作为存储服务器所以不需要配置tracker.conf ；每台服务器配置内容如组名，存放路径等按真实情况填入 ）
17 
18 vim /etc/fdfs/tracker.conf #编辑tracker配置文件
19 disabled=false #启用配置文件
20 bind_addr=     #解析主机地址，空则解析所有主机
21 port=22122     #tracker服务端口
22 connect_timeout=30   #连接超时时间30S
23 network_timeout=60   #网络超时时间60S    
24 base_path=/usr/share/fastdfs/tracker   #tracker基础数据存储路径及日志存放路径
25 max_connections=256  #最大并发连接数
26 work_threads=4         #工作线程数，最好和cpu核数保持一致
27 store_lookup=0         #选择上传文件模式 0代表group轮询 1指定特定group 2选择空间最大的group
28 #store_group=        #上传文件组，如果模式为1，则必须设置成核特定group一致的组名
29 store_server=0        #选择存储服务器上传文件 0代表轮询，1根据通过IP第的顺序 2通过优先级
30 store_path=0        #选择哪块存储盘上传文件 0代表轮询，2代表优先最大存储空间盘(路径)
31 download_server=0    #选择哪台存储服务器下载文件0代表轮询，1代表当前文件上传的源服务器
32 reserved_storage_space = 10% #系统保留存储空间10%
33 ######其余都默认就好
34 
35 vim /etc/fdfs/storage.conf #编辑存储配置文件
36 group_name=group1   #存储组名
37 client_bind=true          #当连接其他服务器时解析该主机地址
38 port=23000                #storage端口 23000
39 base_path=/usr/share/fastdfs/storage  #基础存储数据和日志文件
40 store_path0=/usr/share/fastdfs/storage #group 所占用的目录或硬盘，有几个写几个
41 tracker_server=172.18.4.217:22122  #指定tracker1服务器
42 tracker_server=172.18.4.218:22122  #指定tracker2服务器
43 
44 
45 vim /etc/fdfs/client.conf
46 base_path=/usr/share/fastdfs/client   #基础数据和日志文件
47 tracker_server=172.18.4.217:22122   #tracker1服务器
48 tracker_server=172.18.4.218:22122   #tracker2服务器
  1. 下载安装nginx 及 nginx-fastdfs模块
1 1. 下载安装配置fastdfs-nginx   
 2 https://sourceforge.net/projects/fastdfs/files/?source=navbar 下载nginx-fastdfs模块压缩包
 3 cd /opt/
 4 tar zxvf fastdfs-nginx-module-v1.16.tar.gz
 5 cd fastdfs-nginx-module/src
 6 cp mod_fastdfs.conf /etc/fdfs/ #将mod_fastdfs.conf 拷贝到fdfs下进行配置
 7 vim  /etc/fdfs/mod_fastdfs.conf
 8 base_path=/home/fastdfs/storage  #修改成和storage 存放路径一致
 9 tracker_server=172.12.4.201:22122    #配置成tracker server 地址和端口
10 url_have_group_name = true #url 中是否包组名
11 store_path0=/home/fastdfs/storage #文件存放路径，与storage 一致
12 group_count = 0 #0代表单组，非零代表多组，一般设置几就为几组
13 group_count = 1
14 [group1]
15 group_name=group1
16 storage_server_port=23000
17 store_path_count=1
18 store_path0=/usr/share/fastdfs/storage
19 
20 2. 下载所需依赖库
21 https://sourceforge.net/projects/pcre/files/ #下载所需PCRE
22 cd /opt
23 tar xf pcre-8.12.tar.gz
24 https://sourceforge.net/projects/zlib/ #下载zlib
25 tar xf zlib-1.2.8.tar.xz
26 
27 
28 3. 下载安装nginx
29 wget http://nginx.org/download/nginx-1.8.1.tar.gz  #下载nginx
30 tar -zxvf ngin-1.8.1.tar.gz
31 cd nginx-1.8.1
32 
33 ./configure --prefix=/usr/local/nginx --with-zlib=/opt/zlib-1.2.8     --with-pcre=/opt/pcre-8.12 --add-module=/opt/fastdfs-nginx-module/src
34 make && make install

34             root        html;
35         }
36     }
37 }

配置完成，接下来启动服务并测试：

172.18.4.217-218 三个进程全启动，172.18.4.219 只需要启动storage 和nginx 即可

usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf

/usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

检查是否启动成功：

ps aux |grep fdfs

netstat -ntpl |grep fdfs

ps aux |grep nginx

netstat -ngpl |grep nginx

fdfs_monitor /etc/fdfs/client.conf 查看状态是否正常

  1. 编辑3个文件: echo “1111” >>/opt/1.txt && echo “2222” >>/opt/2.txt && echo “3333” >>/opt/3.txt
  2. 上传文件:

/usr/local/bin/fdfs_test /etc/fdfs/client.conf upload 1.txt

/usr/local/bin/fdfs_test /etc/fdfs/client.conf upload 2.txt

/usr/local/bin/fdfs_test /etc/fdfs/client.conf upload 3.txt

返回结果中会把上传完成的url 打印出来，看三个上传的url group是否轮询变化，如果停掉172.18.4.217 的tracker 返回url是不是地址变成172.18.4.218，

如都成功则 复制URL在浏览器中打开看是否正常
