一、 fastdfs tracker ，storrage 安装
1 安装gcc yum install -y gcc gcc-c++ 2 安装libevent yum -y install libevent 3 安装其他依赖 yum -y install zlib zlib-devel pcre pcre-devel gcc gcc-c++ openssl openssl-devel libevent libevent-devel perl unzip net-tools wget 3 安装 libfastcommon 备注:libfastcommon有很多版本，实测github的 libfastcommonmaster 可以用 下载地址：https://codeload.github.com/xintyan/libfastcommon-master/zip/refs/heads/master 解压对应的zip包: unzip libfastcommon-master-master.zip 进入目录: cd libfastcommon-master-master 然后修改 make.sh 数据权限:chmod 777 make.sh 编译 ./make.sh 安装 ./make.sh install 4 安装 fastdfs 下载地址:https://udomain.dl.sourceforge.net/project/fastdfs/FastDFS%20Server%20Source%20Code/FastDFS%20Server%20with%20PHP%20Extension%20Source%20Code%20V5.08/FastDFS_v5.08.tar.gz 解压缩： tar -zxvf FastDFS_v5.08.tar.gz 进入解压完成的目录：cd FastDFS/ 编译 ./make.sh 安装 ./make.sh install 如果安装成功，/etc/init.d/目录下会有两个f服务启动文件：ls /etc/init.d/ | grep fdfs fdfs_storaged fdfs_trackerd 在/etc/fdfs/ 下面有默认配置文件三个配置文件的例子，我们去掉sample后缀后修改对应参数就能启动了。 client.conf.sample storage.conf.sample tracker.conf.sample 5 启动 tracker 复制配置文件： cp /etc/fdfs/tracker.conf.sample /etc/fdfs/tracker.conf 修改配置文件：vi /etc/fdfs/tracker.conf base_path：监听狗存储数据日志的路径，也可以不改，建议修改 fdfs 默认tracker 和 strorger 存储地址一样 bind_addr：允许范围的地址，默认都允许 port：端口默认22122 （开发测试机才建议这么干）可能需要关闭防火墙：systemctl stop firewalld ，觉得每次关闭麻烦的直接禁用防火墙 开机启动 systemctl disable firewalld 启动 tracker 服务：systemctl start fdfs_trackerd 查看 tracker 服务状态： systemctl status fdfs_trackerd 有需要可以设置成开机启动：chkconfig fdfs_trackerd on 如果想关闭： chkconfig fdfs_trackerd off 6 启动strorage 复制配置文件:cp /etc/fdfs/storage.conf.sample /etc/fdfs/storage.conf 编辑配置文件： base_path：storage存储数据日志的路径 store_path0：这个是存上传文件的路劲 tracker_server：tracker的地址端口 如果修改了新的文件目录需要手动新建： mkdir -p /你指定的路径 启动 tracker 服务：systemctl start fdfs_storaged 检查服务是否启动成功：ps -ef |grep fdfs root 1493 1 0 06:33 ? 00:00:04 /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf root 1529 1 0 06:35 ? 00:00:06 /usr/bin/fdfs_storaged /etc/fdfs/storage.conf
二、 linux 客户端使用
安装fdfs以后，在 /etc/fdfs/ 下有三个例子配置文件，其中一个是客户端的配置文件
-rw-r--r--. 1 root root 1459 Mar 17 06:20 client.conf -rw-r--r--. 1 root root 1461 Mar 17 03:30 client.conf.sample 这个就是client配置文件的例子 -rw-r--r--. 1 root root 858 Mar 17 05:51 http.conf -rw-r--r--. 1 root root 31172 Mar 17 05:51 mime.types -rw-r--r--. 1 root root 3690 Mar 17 05:50 mod_fastdfs.conf -rw-r--r--. 1 root root 7932 Mar 17 04:27 storage.conf -rw-r--r--. 1 root root 7927 Mar 17 03:30 storage.conf.sample -rw-r--r--. 1 root root 7201 Mar 17 03:35 tracker.conf -rw-r--r--. 1 root root 7200 Mar 17 03:30 tracker.conf.sample
复制这个配置文件： cp client.conf.sample client.conf
然后修改：tracker_server=10.10.10.11:22122 和 base_path=/home/fastdfs/client(client存放日志的位置) 到指定位置
查看有那么fdfs相关的程序命令： ls -l /usr/bin/ |grep fdfs
-rwxr-xr-x. 1 root root 315288 Mar 17 03:30 fdfs_appender_test -rwxr-xr-x. 1 root root 315064 Mar 17 03:30 fdfs_appender_test1 -rwxr-xr-x. 1 root root 301920 Mar 17 03:30 fdfs_append_file -rwxr-xr-x. 1 root root 301584 Mar 17 03:30 fdfs_crc32 -rwxr-xr-x. 1 root root 301984 Mar 17 03:30 fdfs_delete_file -rwxr-xr-x. 1 root root 302712 Mar 17 03:30 fdfs_download_file -rwxr-xr-x. 1 root root 302304 Mar 17 03:30 fdfs_file_info -rwxr-xr-x. 1 root root 316112 Mar 17 03:30 fdfs_monitor -rwxr-xr-x. 1 root root 1101712 Mar 17 03:30 fdfs_storaged -rwxr-xr-x. 1 root root 325192 Mar 17 03:30 fdfs_test -rwxr-xr-x. 1 root root 320312 Mar 17 03:30 fdfs_test1 -rwxr-xr-x. 1 root root 447752 Mar 17 03:30 fdfs_trackerd -rwxr-xr-x. 1 root root 302912 Mar 17 03:30 fdfs_upload_appender -rwxr-xr-x. 1 root root 303928 Mar 17 03:30 fdfs_upload_file
上传文件： fdfs_test 配置文件路径 upload 需要上传的文件路径 ，返回 上传后的文件地址
下载：fdfs_test 配置文件路径 download 组名 文件地址 【新文件名字】 （组名就是上传文件返回的第一段）
删除： fdfs_test 配置文件路径 delete 组名 文件地址
三、 Java api 的使用
创建 fdfs_client.conf 文件：
connect_timeout = 2 network_timeout = 30 charset = UTF-8 http.tracker_http_port = 8080 http.anti_steal_token = no http.secret_key = FastDFS1234567890 tracker_server = 10.10.10.11:22122
导入maven 依赖： commons-io 是方便文件处理，不是必须
<dependency> <groupId>net.oschina.zcx7878</groupId> <artifactId>fastdfs-client-java</artifactId> <version>1.27.0.0</version> </dependency> <!-- commons-io --> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency>
上传和下载的例子:
import java.io.File;
import java.io.IOException;
import org.apache.commons.io.FileUtils;
import org.csource.common.MyException;
import org.csource.common.NameValuePair;
import org.csource.fastdfs.ClientGlobal;
import org.csource.fastdfs.StorageClient1;
import org.csource.fastdfs.StorageServer;
import org.csource.fastdfs.TrackerClient;
import org.csource.fastdfs.TrackerServer;
public class Main {
public static void main(String[] args) throws IOException, MyException {
String conf_filename = new Main().getClass().getClassLoader().getResource("fdfs_client.conf").getPath().replaceAll("%20"," ");
ClientGlobal.init(conf_filename);
//建立连接
TrackerClient tracker = new TrackerClient();
TrackerServer trackerServer = tracker.getConnection();
StorageServer storageServer = tracker.getStoreStorage(trackerServer);
StorageClient1 client = new StorageClient1(trackerServer, storageServer);
byte[] fileData = FileUtils.readFileToByteArray(new File( "C:\\Users\\ZHANGYUKUN\\Desktop\\QQ截图20220317164211.png" ));
//上传文件
//设置元信息
NameValuePair[] metaList = new NameValuePair[3];
metaList[0] = new NameValuePair("fileName", "");
metaList[1] = new NameValuePair("fileExtName", "");
metaList[2] = new NameValuePair("fileLength", String.valueOf( fileData.length ));
String fileId = client.upload_file1(fileData, "png", metaList);
System.out.println( fileId );
//下载文件
byte[] file = client.download_file1(fileId);
FileUtils.writeByteArrayToFile(new File("C:\\\\Users\\\\ZHANGYUKUN\\\\Desktop\\\\2.png"), file);
}
}
四、 fastdfs nginx 直联
7 nginx 直连 fastDFS 设置 1. 解压fastdfs nginx 插件： fastdfs-nginx-module_v1.16.tar.gz
2. 修改配置文件把config里面所有的/usr/local替换成/usr（我也不知道为什么这样搞） cd fastdfs-nginx-module/src vi config
3. 安装Nginx的依赖库： yum -y install gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel
4. 下载nginx解压，并且引用fastdfs插件，然后编译安装 下载地址： http://nginx.org/download/nginx-1.20.2.tar.gz 解压：tar -zxvf nginx-1.20.2.tar.gz 进入解压的nginx目录：cd nginx-1.20.2 设置nginx配置文件包含fastdfs 插件：./configure --prefix=/opt/nginx --sbin-path=/usr/bin/nginx --add-module=你的插件所以路径/fastdfs-nginx-module/src 编译安装nginx：make && make install 备注:安装的nginx 的默认位置是 /opt/nginx ，这里面与 配置和日志文件，如果 nginx 启动课访问不到 log 下面的日志里面有范围异常信息 修改nginx配置文件：vi /opt/nginx/conf/nginx.conf 修改图中 server { listen 80; server_name image.smarthome.com; #指定格式的路径，交给FastDFS模块处理 location ~/group([0-9])/ { ngx_fastdfs_module; } location / { root html; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } }
fastdfs nginx插件 默认使用的配置文件路径是/etc/fdfs/mod_fastdfs.conf，我们把插件config目录下得插件配置文件复制过去（插件解压后根目录INSTALL文件里面说的）
5.复制插件配置文件到： cp mod_fastdfs.conf /etc/fdfs/
6. 编辑插件配置文件指向tracker: vi /etc/fdfs/mod_fastdfs.conf tracker_server=tracker_serverIP:端口 url_have_group_name=true store_path0=文件存储位置
5,进入Fast DFS的conf目录，复制 FastDFS 的部分配置文件到/etc/fdfs 目录： cd FastDFS/conf/ cp http.conf mime.types /etc/fdfs/
8.启动nginx ：nginx
9.浏览器访问：ip/group1/M00/00/00/CgoKCmIxpXOAN46wAAAAOtIRWms521.txt 就可以看到对应文件了
五、fdfs 原理
六 fastdfs 集群搭建
1 单个个tracker 多个 storage
我们只要修改多个 storage 里面的group_name=不同的组名，然后连接同一个tracker，这样就可以了。（默认是按照磁盘容量切换 storage ，可以在 tracker 配置文件里面指定负载均衡策略）。
group_name=group2
2 多个tracker，多个storage
1 保持storage 有不同的组名。
group_name=group2
2 分别吧他们都注册到 tracker 上。
tracker_server=192.168.1.200:22122
tracker_server=192.168.1.201:22122
3 是可以使用 fdfs_monitor /etc/fdfs/storage.conf 查看连接情况

3 tracker相互是独立的，没有通讯，他们分别保持着storage的信息（地址，状态，等信息），然后通过groupName 来确定数据放在那个storage。如果storageName 不同，那么他们负载均衡的保存数据，如果groupName相同他们就是互为备份节点。
在storage 内部可以指定多个 store 路径（比如storage主机上有2 个硬盘，我们可以指定 store1=路径a ,store2=路径b ），实测效果是多个store轮流存储文件。有些文档写的是多个store之间是互为备份，这是错的。
store_path_count=n
store_path0=/home/fdfs/storage/store1
store_path1=/home/fdfs/storage/store2
.
.
.
store_path(n-1)=/home/fdfs/storage/store(n)
4 集群下得nginx 级联
编辑插件配置文件：vi /etc/fdfs/mod_fastdfs.conf
修改：store_path0=本地storage得存储地址
url_have_group_name = true
group_name=本地storage组名
tracker_server=192.168.1.200:22122
tracker_server=192.168.1.201:22122(如果有多个tracker得话写多行)
这样就可以在任意storage主机上直连任意一个组的文件了（ ngxin fdfs插件会通过组名给我们找到后端非法到对应住的 storage ）。
如果我们设置两个storage的 groupName=group2的stotrage，那么他们会互为备份，如果一个新的同名节点加入集群（或者暂时离线的节点后面又加入了进来），会复制 数据。
一个文件存储到group2以后两个storage都会有相同的数据
我们使用 fdfs_moniter /etc/fdfs/storage.conf 可以看到 group2 有2 个storage节点
