FastDFS 分布式文件系统安装与使用

本文主要是介绍FastDFS 分布式文件系统安装与使用,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
环境准备
# 关闭防火墙
systemctl disable --now firewalld
systemctl disable --now dnsmasq
systemctl disable --now NetworkManager

# 关闭selinux
setenforce 0
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/sysconfig/selinux
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config

# 关闭分区
swapoff -a && sysctl -w vm.swappiness=0
sed -ri '/^[^#]*swap/s@^@#@' /etc/fstab

yum install git gcc gcc-c++ make automake autoconf libtool pcre pcre-devel zlib zlib-devel openssl-devel wget vim -y
磁盘目录
mkdir /home/dfs #创建数据存储目录
cd /usr/local/src #切换到安装目录准备下载安装包
安装 libfastcommon
git clone https://github.com/happyfish100/libfastcommon.git --depth 1
cd libfastcommon/
./make.sh && ./make.sh install #编译安装
安装 FastDFS
cd ../ #返回上一级目录
git clone https://github.com/happyfish100/fastdfs.git --depth 1
cd fastdfs/
./make.sh && ./make.sh install #编译安装
#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

git clone https://github.com/happyfish100/fastdfs-nginx-module.git --depth 1
cp /usr/local/src/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs
安装 nginx
wget http://nginx.org/download/nginx-1.15.4.tar.gz #下载nginx压缩包
tar -zxvf nginx-1.15.4.tar.gz #解压
cd nginx-1.15.4/
#添加fastdfs-nginx-module模块
./configure --add-module=/usr/local/src/fastdfs-nginx-module/src/ 
make && make install #编译安装
