FastDFS+nginx---（二）安装配置测试

一、简介
FastDFS是一个开源的轻量级的分布式文件系统，它对文件进行管理，功能包括：文件存储、文件同步、文件访问（文件上传、文件下载）等，解决了大容量存储和负载均衡的问题。特别适合以文件为载体的在线服务，如相册网站、视频网站等等。
FastDFS服务端有两个角色：跟踪器（tracker）和存储节点（storage）。跟踪器主要做调度工作，在访问上起负载均衡的作用。
二、安装前准备
1. 系统说明
操作系统：CentOS release 6.5 (Final)
ip：20.10.80.17
主机名：localhost.localdomain
部署角色：tracker storage nginx
2. 准备编译环境 yum -y install gcc gcc+ gcc-c++ openssl openssl-devel pcre pcre-devel
注：参照文件“fastdfs安装前准备组件安装.docx“
3.检测防火墙
检测防火墙是否开启命令：service iptables status
防火墙关闭命令：service iptables stop
注：为了方便测试 关闭防火墙 service iptables stop
三、源码准备
2.1 源码下载,下载后统一拷贝到目录/usr/local/src/
2.1.1 下载fastDFS 5.01 地址：
http://jaist.dl.sourceforge.net/project/fastdfs/FastDFS%20Server%20Source%20Code/FastDFS%20Server%20with%20PHP%20Extension%20Source%20Code%20V5.01/FastDFS_v5.01.tar
2.1.2 下载 nginx 1.7.0：
http://nginx.org/download/nginx-1.7.0.tar.gz
2.1.3 fastdfs-nginx-module_v1.16：
http://jaist.dl.sourceforge.net/project/fastdfs/FastDFS%20Nginx%20Module%20Source%20Code/fastdfs-nginx-module_v1.16.tar.gz

四、安装
4.1 安装FastDFS
cd /usr/local/src/
tar xf FastDFS_v5.01.tar.gz
cd FastDFS
./make.sh && ./make.sh install
4.2 解压fastDFS-nginx-module
cd /usr/local/src/
tar -zxvf fastdfs-nginx-module_v1.16.tar.gz
4.3 安装Nginx
cd /usr/local/src/
tar xf nginx-1.7.0.tar.gz
cd nginx-1.7.0
./configure –user=nginx –group=nginx –prefix=/usr/local/nginx –add-module=../fastdfs-nginx-module/src
make
make install
五、配置
5.1 tracker的配置
a) 创建tracker数据以及日志存放目录
mkdir -p /usr/local/src/fastdfs/tracker
b) 修改FastDFS的tracker.conf配置文件
vim /etc/fdfs/tracker.conf
主要修改项：
base_path= /usr/local/src/fastdfs/tracker
max_connections=100
work_threads=8
store_lookup=0
store_path=0
reserved_storage_space=10%
run_by_group=root
run_by_user=root
rotate_error_log=true
5.2 修改Nginx的配置文件
vim /usr/local/nginx/conf/nginx.conf
修改后内容如下：
user root root; —用户 用户组
worker_processes 3;
error_log /usr/local/nginx/logs/error.log;
error_log /usr/local/nginx/logs/error.log notice;
error_log /usr/local/nginx/logs/error.log info;
pid /usr/local/nginx/logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 50m;
log_format main ‘$remote_addr -$remote_user [$time_local] "$request”
‘$status$body_bytes_sent “$http_referer” ’ ‘”$http_user_agent" "$http_x_forwarded_for”’;
access_log /usr/local/nginx/logs/access.log main;
upstream server_group1{
server 20.10.80.17:80;
}
server {
listen 80;
server_name localhost.localdomain;
access_log off;
location /group1/M00 {
root /usr/local/src/fastdfs/storage/data;
ngx_fastdfs_module;
}
}
}
5.3 将tracker交给service管理并且设置开机启动
a)cp /usr/local/src/FastDFS/init.d/fdfs_trackerd /etc/init.d/
b)chkconfig –add fdfs_trackerd
c)chkconfig fdfs_trackerd on
d)service fdfs_trackerd start
六、配置storage
a) 创建数据存放目录
mkdir -p /usr/local/src/ fastdfs/storage/data
b) 修改FastDFS的storage.conf配置文件
vim /etc/fdfs/storage.conf
修改主要项目如下：
work_threads=8
store_path_count=1
base_path=/usr/local/src/ fastdfs/storage
store_path0=/usr/local/src/ fastdfs/storage

tracker_server 的地址

tracker_server=20.10.80.17:22122

运行 FastDFS 的用户组

run_by_group=root

运行 FastDFS 的用户

run_by_user=root
file_distribute_path_mode=1
rotate_error_log=true
c) 把nginx模块的配置文件拷贝到 /etc/fdfs中，进行修改
cp /usr/local/src/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/
主要修改项
connect_timeout=30
tracker_server=20.10.80.17:22122
group_name=group1
url_have_group_name = true
store_path_count=1
store_path0=/usr/local/src/ fastdfs/storage
d) 修改nginx配置文件
vim /usr/local/nginx/conf/nginx.conf
修改后内容如下：
user root root; —用户 用户组
worker_processes 3;
error_log /usr/local/nginx/logs/error.log;
error_log /usr/local/nginx/logs/error.log notice;
error_log /usr/local/nginx/logs/error.log info;
pid /usr/local/nginx/logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 50m;
log_format main ‘$remote_addr -$remote_user [$time_local] "$request”
‘$status$body_bytes_sent “$http_referer” ’ ‘”$http_user_agent" "$http_x_forwarded_for”’;
access_log /usr/local/nginx/logs/access.log main;
upstream server_group1{
server 20.10.80.17:80;
}
server {
listen 80;
server_name localhost.localdomain;
access_log off;
location /group1/M00 {
root /usr/local/src/fastdfs/storage/data;
ngx_fastdfs_module;
}
}
}

e) 创建软连接
ln –s /usr/local/src/fastdfs/storage/data /usr/local/src/fastdfs/storage/data/M00
f)把storage 交给service管理并且设置开机启动
cp /usr/local/src/FastDFS/init.d/fdfs_storaged /etc/init.d/
chkconfig –add fdfs_storaged
chkconfig fdfs_storaged on
service fdfs_storaged start

g) nginx扩展模块，不能正常显示图片的问题
在配置文件/etc/fdfs/mod_fastdfs.conf中，缺省的设置是这样的：http.need_find_content_type=false这个参数在nginx中需要设置为true，apache中应该设置为false
h)400 bad request
[2011-12-12 15:24:21] ERROR - file: /tmp/fastdfs-nginx-module/src/common.c, line: 561, logic file: M00/00/00/wKgBNU7lqyjzJZ4mAA4CRXl5SCQ670.jpg not exists
2011/12/12 15:24:21 [error] 14147#0: *1 open() “/home/nginx/nginx/html/favicon.ico” failed (2: No such file or directory), client: 192.168.1.123, server: localhost, request: “GET /favicon.ico HTTP/1.1”, host: “20.10.80.17:80”
修改/fastdfs/conf/mod_fastdfs.conf里面url_have_group_name = true

七、测试
1. 在20.10.80.17上启动tracker，storage，nginx
service fdfs_trackerd start
service fdfs_storaged start
/usr/local/nginx/sbin/nginx
2. 配置一个client 在tracker上进行
vim /etc/fdfs/client.conf
base_path= /usr/local/src/fastdfs/storage
tracker_server=20.10.80.17:22122
3. 查看集群详细
fdfs_monitor /etc/fdfs/client.conf
4. 测上传
fdfs_upload_file /etc/fdfs/client.conf /usr/fastdfs/hibernate.jpg
返回：/group1/M00/00/00/wKhQFFWYq1iAXUcbAAF9-d2hUpA735.jpg
5.浏览器访问http://20.10.80.17/group1/M00/00/00/wKhQFFWYx6WAaeCIAALJTvfxx5I331.jpg检测上传是否成功
