centos7下安装FastDFS分布式文件存储系统

在CentOS 7下安装FastDFS分布式文件系统，可以遵循以下步骤：

1. 安装依赖库

sudo yum install -y git gcc gcc-c++ make automake autoconf libtool pcre pcre-devel zlib zlib-devel openssl-devel

2. 下载FastDFS源码

git clone https://github.com/happyfish100/fastdfs.git
git clone https://github.com/happyfish100/libfastcommon.git

3. 编译安装libfastcommon

cd libfastcommon/
./make.sh && sudo ./make.sh install

4. 编译安装FastDFS

cd ../fastdfs/
./make.sh && sudo ./make.sh install

5. 修改配置文件（按需修改以下配置文件路径和参数）

sudo cp /etc/fdfs/tracker.conf.sample /etc/fdfs/tracker.conf
sudo cp /etc/fdfs/storage.conf.sample /etc/fdfs/storage.conf
sudo cp /etc/fdfs/client.conf.sample /etc/fdfs/client.conf

6. 启动tracker

/etc/init.d/fdfs_trackerd start

7. 启动storage

/etc/init.d/fdfs_storaged start

8. 测试上传文件

/usr/bin/fdfs_test /etc/fdfs/client.conf upload 测试文件路径

以上步骤仅提供了安装和基本配置的示例，实际部署时需要根据服务器环境和需求做出相应的调整。
