centos7 安装FastDFS分布式文件系统
一、版本介绍：
系统：centos7.1
FastDFS：5.08
libfastcommon：1.30
fastdfs-nginx-module：1.16
nginx：1.10.1
二、服务器结构：
两台服务器：172.0.0.190【fastdfs_1】、172.0.0.171【fastdfs_2】
每一台都充当 tracker 与 storage 的角色，配置都一样
三、安装需要用到的应用与类库：
[root@fastdfs_1 pangyiguang]# yum install vim wget zlib zlib-devel pcre pcre-devel gcc gcc-c++ openssl openssl-devel libevent libevent-devel perl net-tools unzip
四、配置hosts
[root@fastdfs_1 pangyiguang]# vim /etc/hosts
追加内容（这里的server不能绑定127.0.0.1，否则报错）：
172.0.0.190 fastdfs-server1
172.0.0.171 fastdfs-server2
五、添加用户与组
[root@fastdfs_1 pangyiguang]# groupadd www
[root@fastdfs_1 pangyiguang]# useradd -s /sbin/nologin -g www www
[root@fastdfs_1 pangyiguang]# groupadd fastdfs
[root@fastdfs_1 pangyiguang]# useradd -s /sbin/nologin -g fastdfs fastdfs
六、创建环境目录
[root@fastdfs_1 pangyiguang]# mkdir -p /servers/nginx
[root@fastdfs_1 pangyiguang]# mkdir -p /data/fastdfs/storage
[root@fastdfs_1 pangyiguang]# chown -R fastdfs:fastdfs /data/fastdfs
七、下载并解压安装包
[root@fastdfs_1 pangyiguang]# cd ~
[root@fastdfs_1 ~]# wget http://ncu.dl.sourceforge.net/project/fastdfs/FastDFS%20Nginx%20Module%20Source%20Code/fastdfs-nginx-module_v1.16.tar.gz
[root@fastdfs_1 ~]# wget http://nchc.dl.sourceforge.net/project/fastdfs/FastDFS%20Server%20Source%20Code/FastDFS%20Server%20with%20PHP%20Extension%20Source%20Code%20V5.08/FastDFS_v5.08.tar.gz
[root@fastdfs_1 ~]# wget https://codeload.github.com/happyfish100/libfastcommon/zip/master -O libfastcommon.zip
[root@fastdfs_1 ~]# wget http://nginx.org/download/nginx-1.10.1.tar.gz
如果下载不了，可以从百度云这里下载：http://pan.baidu.com/s/1eSeAkZg
解压：
[root@fastdfs_1 ~]# tar zxf fastdfs-nginx-module_v1.16.tar.gz
[root@fastdfs_1 ~]# tar zxf FastDFS_v5.08.tar.gz
[root@fastdfs_1 ~]# unzip libfastcommon.zip
[root@fastdfs_1 ~]# tar zxf nginx-1.10.1.tar.gz
八、安装libfastcommon类库
[root@fastdfs_1 ~]# cd ~/libfastcommon-master/
[root@fastdfs_1 libfastcommon-master]# ./make.sh
[root@fastdfs_1 libfastcommon-master]# ./make.sh install
九、安装与配置FastDFS
[root@fastdfs_1 libfastcommon-master]# cd ~/FastDFS
[root@fastdfs_1 FastDFS]# ./make.sh
[root@fastdfs_1 FastDFS]# ./make.sh install
[root@fastdfs_1 FastDFS]# cp conf/* /etc/fdfs/
编辑：client.conf
[root@fastdfs_1 fdfs]# vim client.conf
更改对应内容：
base_path=/data/fastdfs/storage
tracker_server=fastdfs-server1:22122
tracker_server=fastdfs-server2:22122
编辑：storage.conf
[root@fastdfs_1 fdfs]# vim storage.conf
更改对应内容：
group_name=group1
base_path=/data/fastdfs/storage
store_path0=/data/fastdfs/storage
tracker_server=fastdfs-server1:22122
tracker_server=fastdfs-server2:22122
http.server_port=80
编辑：tracker.conf
[root@fastdfs_1 fdfs]# vim tracker.conf
更改对应内容：
base_path=/data/fastdfs/storage
run_by_group=fastdfs
run_by_user=fastdfs
use_storage_id = false
http.server_port=80
十、安装配置nginx与fastdfs模块
[root@fastdfs_1 fdfs]# cd ~/nginx-1.10.1
[root@fastdfs_1 nginx-1.10.1]# ./configure --prefix=/servers/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --add-module=/root/fastdfs-nginx-module/src/ --user=www --group=www
[root@fastdfs_1 nginx-1.10.1]# make && make install
############################如果出现以下这个错误：############################
/root/fastdfs-nginx-module/src//common.c:21:25: 致命错误：fdfs_define.h：没有那个文件或目录
#include "fdfs_define.h"
^
编译中断。
make[1]: *** [objs/addon/src/ngx_http_fastdfs_module.o] 错误 1
make[1]: 离开目录“/root/nginx-1.10.1”
make: *** [build] 错误 2
说明添加fastdfs模块出错，可以更改fastdfs-nginx-module/src/config这个文件
[root@fastdfs_1 nginx-1.10.1]# vim ~/fastdfs-nginx-module/src/config
更改后内容为：
ngx_addon_name=ngx_http_fastdfs_module
HTTP_MODULES="$HTTP_MODULES ngx_http_fastdfs_module"
NGX_ADDON_SRCS="$NGX_ADDON_SRCS $ngx_addon_dir/ngx_http_fastdfs_module.c"
CORE_INCS="$CORE_INCS /usr/include/fastdfs /usr/include/fastcommon/"
CORE_LIBS="$CORE_LIBS -L/usr/lib -lfastcommon -lfdfsclient"
CFLAGS="$CFLAGS -D_FILE_OFFSET_BITS=64 -DFDFS_OUTPUT_CHUNK_SIZE='256*1024' -DFDFS_MOD_CONF_FILENAME='\"/etc/fdfs/mod_fastdfs.conf\"'"
然后再进行上面的两个步骤：
[root@fastdfs_1 nginx-1.10.1]# ./configure --prefix=/servers/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --add-module=/root/fastdfs-nginx-module/src/ --user=www --group=www
[root@fastdfs_1 nginx-1.10.1]# make && make install
############################如果出现以上这个错误：############################
把对应的配置文件拷贝到对应的配置路径：
[root@fastdfs_1 nginx-1.10.1]# cp ~/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/
编辑模块配置文件：
[root@fastdfs_1 nginx-1.10.1]# vim /etc/fdfs/mod_fastdfs.conf
更改以下对应内容：
base_path=/data/fastdfs/storage
use_storage_id = false
tracker_server=fastdfs-server1:22122
tracker_server=fastdfs-server2:22122
group_name=group1
url_have_group_name = true
store_path0=/data/fastdfs/storage
接着更改nginx的配置文件：
[root@fastdfs_1 nginx-1.10.1]# vim /servers/nginx/conf/nginx.conf
把 sever指令段内容改为：
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
location /group1/M00 {
root /data/fastdfs/storage/data;
ngx_fastdfs_module;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
十一、授权对应的端口开放：
[root@fastdfs_1 nginx-1.10.1]# firewall-cmd --zone=public --add-port=80/tcp --permanent
[root@fastdfs_1 nginx-1.10.1]# firewall-cmd --zone=public --add-port=22122/tcp --permanent
[root@fastdfs_1 nginx-1.10.1]# firewall-cmd --zone=public --add-port=23000/tcp --permanent
[root@fastdfs_1 nginx-1.10.1]# firewall-cmd --reload
[root@fastdfs_1 nginx-1.10.1]# firewall-cmd --list-all
上面的配置过程就是其中一台主机的配置，因为两台主机的配置时一样的，重复上面的 【三 ~ 十一】的流程就可以了，如果是虚拟机，直接clone刚才那个镜像就可以了。假如上面的这台ip是172.0.0.190 ，那么另外一台ip就是172.0.0.171。
好了下面就是使用的过程了：
启动：
[root@fastdfs_1 pangyiguang]# /etc/init.d/fdfs_storaged start
[root@fastdfs_1 pangyiguang]# /etc/init.d/fdfs_trackerd start
[root@fastdfs_1 pangyiguang]# /servers/nginx/sbin/nginx 
[root@fastdfs_2 pangyiguang]# netstat -lpna | grep -E "nginx|fdfs"
查看faskFDS的运行状态信息：
[root@fastdfs_1 pangyiguang]# fdfs_monitor /etc/fdfs/storage.conf
