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

将libfastcommon、fastdfs和fastdfs-nginx解压文件放到 home/fdfs下
cd libfastcommon-master/

./make.sh && ./make.sh install 

若提示权限不够可使用chmod u+x *.sh设置权限

mkdir -p /usr/lib64
mkdir -p /usr/lib
mkdir -p /usr/include/fastcommon

cd fastdfs-master/

./make.sh && ./make.sh install

若提示权限不够可使用chmod u+x *.sh设置权限

mkdir -p /usr/bin
mkdir -p /etc/fdfs
mkdir -p /usr/lib64
mkdir -p /usr/lib

cp -r /home/fdfs/fastdfs-master/conf
