Fastdfs 带http和client的环境搭建<1> 晴

环境 RHEL5.3
软件
  FastDFS_v1.28.tar.gz
  libevent-1.4.9-stable.tar.gz
  php
  php-devel

#测试目的
   节点开启自运行
   接待你提供http下载

准备:
跟踪器 tracker ; 存储器 storage; 客户端 client
跟踪器安装fastdfs
存储器安装fastdfs
client安装fastdfs php的fastdfs扩展

=================================================================
 
一 下载安装fastdfs
1#要想支持web，得需要配置libevent
#安装libevent
cd /opt
wget http://down1.chinaunix.net/distfiles/libevent-1.4.9-stable.tar.gz
tar zxvf libevent-1.4.9-stable.tar.gz
cd libevent-1.4.9-stable
./configure --prefix=/usr
make;make install
#安装fastdfs
cd /opt
wget  http://fastdfs.googlecode.com/files/FastDFS_v1.28.tar.gz
tar FastDFS_v1.28.tar.gz
cd FastDFS
#编译make.sh 以主持web和开机自动脚本
vi make.sh #去掉这两行的注视
...
WITH_HTTPD=1 #支持web,client可以不开启这个功能
WITH_LINUX_SERVICE=1 #支持开机脚本
...
# 编译
./make.sh &&　./make.sh install
============================================================================


2 、修改配置文件
FastDFS 分为三种角色（跟踪器 tracker ; 存储器 storage; 客户端 client），三种角色的配置文件时不相同的，需要注意的是，三种角色都需要编译安装fastdfs，即执行前三步,作为client是可以不打开WITH_HTTPD=1这个功能的。当编译安装完fastdfs后，自动会在/etc/fdfs下面生成client.conf  http.conf  mime.types  storage.conf  tracker.conf 这些文件的，只要我们稍微改动一下就可以了。

#tracker节点:
[root@hdfs-1 ~]# mkdir /install/fastdfs/
[root@hdfs-1 ~]# /etc/init.d/fdfs_trackerd start
Starting FastDFS tracker server:
#存储节点
[root@hdfs-2 ~]# mkdir /install/fastdfs/
[root@hdfs-2 ~]# mkdir /install/fastdfs1/ #真正存放数据的地方！
[root@hdfs-2 ~]# /etc/init.d/fdfs_storaged start
