一、FastDFS安装

官方安装文档

按照前两步安装好libfatscommon和FastDFS后

配置文件准备

cp /etc/fdfs/tracker.conf.sample /etc/fdfs/tracker.conf
cp /etc/fdfs/storage.conf.sample /etc/fdfs/storage.conf
cp /etc/fdfs/client.conf.sample /etc/fdfs/client.conf #客户端文件，测试用
cp /usr/local/src/fastdfs/conf/http.conf /etc/fdfs/ #供nginx访问使用
cp /usr/local/src/fastdfs/conf/mime.types /etc/fdfs/ #供nginx访问使用

tracker配置

# 在家目录创建tracker文件夹存放相关数据
mkdir /home/i6000/fast/trackervi 
/etc/fdfs/tracker.conf
# 设置tracker数据文件存放路径
base_path=/home/i6000/fast/tracker

storage配置

# 在家目录插件storage文件夹存放相关数据
mkdir /home/i6000/fast/storage
vi /etc/fdfs/storage.conf
# 设置storage相关文件存放路径
base_path=/home/i6000/fast/storage
## 修改tracker的ip
tracker_server=192.168.229.130:22122
# 设置数据存储路径
store_path0=/home/i6000/fast/storage

client 配置

# 设置tracker相关文件存放路径
base_path= /home/i6000/fast/tracker
# 当前机器ip
tracker_server=192.168.52.1:22122

启动

cd /etc/fdfs
fdfs_trackerd ./tracker.conf
# storage配置文件要指定绝对路径,启动后会在storage下文件两个文件夹
fdfs_storaged /etc/fdfs/storage.conf

测试上传文件

你可以在storage_path/00/00下找到这这张图片

二、nginx安装

1、安装fastdfs-nginx-module

2、安装nginx

# --prefix指定安装文件夹， --add-module安装一个子模块
./configure --prefix=/usr/local/nginx/ --add-module=/home/i6000/fast/fastdfs-nginx-module-master/src
make && make install #编译安装

删掉objs/Makefilel里面的-Werror

编译

make
make install

# 拷贝配置文件
cp fastdfs-nginx-module-master/src/mod_fastdfs.conf /etc/fdfs/
# 修改以下配置
connect_timeout=10 # 超时时间
base_path=/home/i6000/fast/tracker
tracker_server=192.168.229.130:22122
store_path0=/home/i6000/fast/storage
url_have_group_name = true
## 拷贝配置文件
cp fast/fastdfs-master/conf/http.conf  /etc/fdfs/
cp fast/fastdfs-master/conf/mime.types  /etc/fdfs/

修改nginx配置

# 到上面安装nginx是指定的目录
cd /usr/local/nginx/conf
vi nginx.conf

在keepalive_timeout  65;下面添加如下配置：
server {
            listen       8888;
            server_name  localhost;
            location ~/group[0-9]/ {
                ngx_fastdfs_module;
            }
            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                root   html;
            }
    }

启动nginx

cd /usr/local/nginx/sbin
./nginx

测试

打开网址：ip/nginx_port/上传图片时返回的那串代码

三、Go上传及读取图片

安装依赖库

• 下载

go get github.com/weilaihui/fdfs_client

• 如果有报错先执行下面命令再执行上面的

cd  ~/workspace/go/src
mkdir -p golang.org/x
cd golang.org/x
git clone https://github.com/golang/crypto.git
git clone https://github.com/golang/sys.git

上传图片

1、添加配置文件

我这里是windows连虚拟机
新建一个client.conf文件，修改相关配置

# connect timeout in seconds
# default value is 30s
connect_timeout=30

# network timeout in seconds
# default value is 30s
network_timeout=60

# the base path to store log files
base_path=/home/i6000/fast/tracker

# tracker_server can ocur more than once, and tracker_server format is
#  "host:port", host can be hostname or ip address
# 虚拟机的ip和端口
tracker_server=192.168.229.130:22122

#standard log level as syslog, case insensitive, value list:
### emerg for emergency
### alert
### crit for critical
### error
### warn for warning
### notice
### info
### debug
log_level=info


#HTTP settings
http.tracker_server_port=80

#use "#include" directive to include HTTP other settiongs
##include http.conf

2、上传测试

// 新建fdfs客户端
    client, err := fdfs_client.NewFdfsClient("conf/client.conf")
    if err != nil{
        beego.Info("fdfs连接错误：", err)
        return ""
    }

    // 获取一个字节数组，大小和文件相等
    fileBuffer := make([]byte, head.Size)
    // 写入图片信息
    file.Read(fileBuffer)
    // 上传文件到fdfs
    res, err := client.UploadByBuffer(fileBuffer, ext[1:])
    if err != nil{
        beego.Info("上传fdfs失败：", err)
        return ""
    }
    beego.Info("上传fdfs成功：", res)
    return "1"

3、页面前台读取

<!-- 配置nginx的ip：端口/上传图片时的返回码 -->
