分布式文件存储fastdfs

我的博客已迁移到xdoujiang.com请去那边和我交流
FastDFS是一个开源的轻量级应用级的分布式文件存储服务，它对文件进行管理，功能包括：
文件存储、文件同步、文件访问（文件上传、文件下载）等解决了大容量存储和负载均衡的问题。
特别适合以文件为载体的在线服务，如相册网站、视频网站等等。

FastDFS有三个角色：跟踪服务器(tracker server)、存储服务器(storage server)和客户端(client)。
1)跟踪服务器:主要做调度工作 起负载均衡的作用
2)存储服务器:存储节点存储文件 完成文件管理的所有功能：存储、同步和提供存取接口
3)客户端:可以使用fdfs_upload_file、c、php、java、python、.net等api接口
使用TCP/IP协议与跟踪器服务器或存储节点进行数据交互

一、基础环境
1、角色、ip、版本、内核、fastdfs、fastdfs-nginx-module、nginx
serverA 10.1.10.117 3.2.0-4-amd64 7.8 tracker nginx
serverB 10.1.10.185 3.2.0-4-amd64 7.8 storage fastdfs-nginx-module nginx group1
serverC 10.1.10.194 3.2.0-4-amd64 7.8 storage fastdfs-nginx-module nginx group1
client 10.1.10.117
fastdfs版本5.05
fastdfs-nginx-module版本1.15

libfastcommon版本1.3

2、安装基础包
apt-get -y install git wget gcc make libpcre3-dev libpcre3 libssl-dev zlib1g-dev
axel libc6-dev libc-bin curl

二、在serverA上安装fastdfs的tracker角色
1、git方式下载
git clone https://github.com/happyfish100/libfastcommon.git libfastcommon
git clone https://github.com/happyfish100/fastdfs.git fastdfs

2、编译安装
1)cd libfastcommon
bash make.sh
bash make.sh install
2)cd fastdfs
bash make.sh
bash make.sh install

3、查看相应命令具体在哪里
ll /usr/bin/fdfs*
-rwxr-xr-x 1 root root  349008 Aug 21 14:12 /usr/bin/fdfs_appender_test

-rwxr-xr-x 1 root root  334835 Aug 21 14:12 /usr/bin/fdfs_upload_appender
-rwxr-xr-x 1 root root  336773 Aug 21 14:12 /usr/bin/fdfs_upload_file

4、创建数据目录
mkdir -p /opt/fastdfs/tracker

5、创建组和用户
groupadd fastdfs
useradd -s /bin/bash -d /opt/fastdfs/ -g fastdfs fastdfs

6、修改相关目录权限
chown -R fastdfs.fastdfs /opt/fastdfs

7、修改配置
1)备份配置
cp /etc/fdfs/tracker.conf.sample /etc/fdfs/tracker.conf
2)修改配置/etc/fdfs/tracker.conf(serverA)
sed -i 's/bind_addr=.*/bind_addr=10.1.10.117/' /etc/fdfs/tracker.conf
sed -i 's!base_path=.*!base_path=/opt/fastdfs/tracker/!g' /etc/fdfs/tracker.conf
sed -i 's!run_by_group=.*!run_by_group=fastdfs!g' /etc/fdfs/tracker.conf
sed -i 's!run_by_user=.*!run_by_user=fastdfs!g' /etc/fdfs/tracker.conf

8、启动服务tracker
1)使用ldd命令检查相应支持模块
ldd /usr/bin/fdfs_trackerd
linux-vdso.so.1 =>  (0x00007ffd4abb3000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f5dd7c48000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f5dd7a44000)
libfastcommon.so => not found
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f5dd76b8000)
/lib64/ld-linux-x86-64.so.2 (0x00007f5dd7e6a000)
PS:查看到libfastcommon.so => not found 目前不找到
2）先找下libfastcommon.so这个文件在哪里
find / -name "libfastcommon.so"
/root/libfastcommon/src/libfastcommon.so
/usr/lib64/libfastcommon.so
2)加载libfastcommon.so
echo "/usr/lib64" > /etc/ld.so.conf.d/libfastcommon.conf
ldconfig
3)再次查看下
ldd /usr/bin/fdfs_trackerd
linux-vdso.so.1 =>  (0x00007ffebedd2000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f3732ddb000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f3732bd7000)
libfastcommon.so => /usr/lib64/libfastcommon.so (0x00007f37329ae000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f3732623000)

五、测试
1、在tracker上的操作[作为client测试]
1)备份配置
cp /etc/fdfs/client.conf.sample /etc/fdfs/client.conf
2)修改配置
diff /etc/fdfs/client.conf.sample /etc/fdfs/client.conf
10c10
< base_path=/home/yuqing/fastdfs
---
> base_path=/tmp
14c14
< tracker_server=192.168.0.197:22122
---
> tracker_server=10.1.10.117:22122

2、上传文件测试
root@10.1.10.117:~# fdfs_test /etc/fdfs/client.conf upload Chrysanthemum.jpg

3、windows上访问地址测试效果

六、在ServerA上安装nginx(前端提供负载均衡)并进行测试
1、建立nginx用户
groupadd nginx
useradd nginx -g nginx -s /bin/false

2、下载nginx
axel -n 10 http://nginx.org/download/nginx-1.4.7.tar.gz 
3、解压
tar zxvf nginx-1.4.7.tar.gz && cd nginx-1.4.7

4、编译三部曲
./configure --prefix=/opt/nginx --user=nginx --group=nginx --with-http_ssl_module
make && make install

5、为了方便 弄个软链接
ln -s /opt/nginx/sbin/nginx /usr/local/sbin/nginx

6、备份配置
cp /opt/nginx/conf/nginx.conf /opt/nginx/conf/nginx.conf.bak

7、修改配置
diff /opt/nginx/conf/nginx.conf /opt/nginx/conf/nginx.conf.bak
3d2
< user nginx;
35,38c34
< upstream group1{
< server 10.1.10.185:80;
< server 10.1.10.194:80;
< }
---
>
40,41c36,37
<         listen       10.1.10.117:80;
<         server_name  10.1.10.117;
---
>         listen       80;
>         server_name  localhost;
47c43
<         location /group1/M00 {
---
>         location / {
50d45
<             proxy_pass  http://group1; 
8、启动服务
nginx

9、设置开机启动
echo "/usr/local/sbin/nginx" >> /etc/rc.local

10、查看端口和进程
ps -ef |grep nginx
root      14627      1  0 15:09 ?        00:00:00 nginx: master process nginx
nginx     14628  14627  0 15:09 ?        00:00:00 nginx: worker process
netstat -tupnl |grep nginx
tcp        0      0 10.1.10.117:80          0.0.0.0:*               LISTEN      16986/nginx: master

11、再次上传图片测试
