Centos安装FastDFS+Nginx(一天时间搞定)

复制提示
最近在研究和使用Fastdfs，别人搭的环境，终究是别人的，绝知此事要躬行~躬行啊~
下面的脚本主要参考了官方的INSTALL文件，这个是比较权威的，部分地方和实际情况不一致。
比如配置文件的名字，Fastdfs的安装位置。
一、下载
https://github.com/happyfish100/fastdfs fastdfs-5.05.zip
https://github.com/happyfish100/libfastcommon libfastcommon-1.0.7.zip
https://github.com/happyfish100/fastdfs-nginx-module fastdfs-nginx-module.zip
二、安装
先安装libfastcommon-1.0.7.zip
解压命令 unzip libfastcommon-1.0.7.zip
cd libfastcommon-1.0.7
./make.sh
./make.sh install
再安装fastdfs
unzip fastdfs-5.05.zip
./make.sh
./make.sh install
如果没有先安装libfastcommon，会报错
"执行 ./make.sh 报以下错误：
cc -Wall -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE -g -O -DDEBUG_FLAG -DOS_LINUX -DIOEVENT_USE_EPOLL -c -o ../common/fdfs_global.o ../common/fdfs_global.c -I../common -I/usr/include/fastcommon
../common/fdfs_global.c:20:20: fatal error: logger.h: No such file or directory
#include "logger.h"
^
compilation terminated."
三、配置和启动
配置文件的位置
/etc/fdfs/tracker.conf
/etc/fdfs/storage.conf
我的CentOS/etc/fdfs 有3个文件client.conf.sample、storage.conf.sample、tracker.conf.sample
直接重命名这3个文件为，*.conf，修改配置~
先启动tracker
/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart
再启动storage
/usr/bin/fdfs_storaged /etc/fdfs/storage.conf restart
很奇怪，为啥没有start命令，而是restart？
[root@AY1304131823374920ac ~]# ps -ef|grep tracker
root 25433 1 0 16:26 ? 00:00:00 /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart
[root@AY1304131823374920ac ~]# ps -ef|grep storage
root 25533 1 2 16:28 ? 00:00:00 /usr/bin/fdfs_storaged /etc/fdfs/storage.conf restart
四、上传
#把配置文件上传了
/usr/bin/fdfs_test /etc/fdfs/client.conf upload /etc/fdfs/client.conf
[root@AY1304131823374920ac logs]# /usr/bin/fdfs_test /etc/fdfs/client.conf upload /etc/fdfs/client.conf
This is FastDFS client test program v5.05

五、监控
/usr/bin/fdfs_monitor /etc/fdfs/client.conf
[root@AY1304131823374920ac logs]# /usr/bin/fdfs_monitor /etc/fdfs/client.conf
[2015-10-28 17:25:13] DEBUG - base_path=/root/fdfsdata, connect_timeout=30, network_timeout=60, tracker_server_count=1, anti_steal_token=0, anti_steal_secret_key length=0, use_connection_pool=0, g_connection_pool_max_idle_time=3600s, use_storage_id=0, storage server id count: 0
server_count=1, server_index=0
tracker server is 42.96.184.84:22122
group count: 1
Group 1:
group name = group1
disk total space = 20157 MB
disk free space = 12235 MB
trunk free space = 0 MB
storage server count = 1
active server count = 1
storage server port = 23000
storage HTTP port = 8888
store path count = 1
subdir count per path = 256
current write server index = 0
六、访问文件
网上找了下，自带的Http可能不能使用，可能啊~
server {
46 listen 80;
47 server_name file.fansunion.cn;
48
49 location /group1/M00 {
50 root /root/fdfsdata/data;
51 #ngx_fastdfs_module;
52 }
53 }
Nginx配置没有使用ngx_fastdfs_module这个模块，出现了403.
http://file.fansunion.cn/group1/M00/00/00/KmC4VFYwlQGAItigAAAFsHrMXek69_big.conf
403 Forbidden
nginx/1.6.2
本地host已经配置了 42.96.184.84 file.fansunion.cn
七、尝试安装ngx_fastdfs_module，因为之前总是403各种问题
参考ngx_fastdfs_module中的INSTALL文档
1.源码安装Nginx，之前的Nginx是直接安装的
Nginx下载地址 http://nginx.org/en/download.html
写在之前的Nginx，yum remove nginx
在安装Nginx之前，可能需要安装gcc、 openssl-devel、 pcre-devel和zlib-devel软件库，具体如下：
#没用
yum install gcc-c++
#没用
yum install openssl-devel
#用了
yum install pcre-devel
#用了
yum install zlib-devel
./configure --add-module=/root/soft/fastdfs-nginx-module-master/src
make;
make install;
#检查语法
/usr/local/nginx/sbin/nginx -t
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
从这里可以看出，默认使用的是/usr/local/nginx/conf/nginx.conf这个配置文件
而之前手动命令安装，配置文件在/etc/nginx目录下，这个需要注意哦~
#启动-指定配置文件
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
#
/usr/local/nginx/sbin/nginx -s reload
ps -ef|grep nginx
root 20897 1 0 10:39 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
root 20918 13217 0 10:40 pts/3 00:00:00 grep nginx
再次上传 /usr/bin/fdfs_test /etc/fdfs/client.conf upload /etc/fdfs/client.conf
访问文件 http://file.fansunion.cn/group1/M00/00/00/KmC4VFYwlQGAItigAAAFsHrMXek69_big.conf
ln -s /root/fdfsdata/data /root/fdfsdata/data/M00
八、搞了半天还没有搞好，气死我了啊~
配置防火墙，重新启动，重新上传
iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 23000 -j ACCEPT
/etc/init.d/iptables save
/usr/local/nginx/sbin/nginx
/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart
/usr/bin/fdfs_storaged /etc/fdfs/storage.conf restart
/usr/bin/fdfs_test /etc/fdfs/client.conf upload /etc/fdfs/client.conf
http://42.96.184.84:8080/group1/M00/00/00/KmC4VFYxlIWAOq-xAAAFsCOGhRQ76_big.conf
netstat -ano |grep 8080
各种调试Nginx，都报错，连最基本的配置都找不到了~
看Nginx的日志，也没有发现，最后才晓得，Nginx源码安装的日志文件位于“/usr/local/nginx/logs”。
里面报错了，提示/etc/fdfs/下没有mod_fastdfs.conf这个文件~
拷贝一份http.conf到 /etc/fdfs目录下
九、麻痹，麻痹啊~终于搞定了~
1.base_path 放在/root/fdfsdata和/root/fdfsdata2 下，都提示权限不足。
放在了/home/fdfsdata下就行了。
2.mime.types等配置文件，凡是提示找不到，就从fastdfs等原文件的conf目录copy一份到/etc/fdfs/
3.400或404
可能是Nginx配置或者group-name那个true选项
没有开启groupname的
http://42.96.184.84:8080/M00/00/00/KmC4VFYxy2OAAqGdAAAFrZvGHAA99.conf
server {
36 listen 80;
37 server_name 42.96.184.84 alias file.test;
38
39 location / {
40 # root /root/fdfsdata/data;
41 # ngx_fastdfs_module;
42 root /home/www;
43 index a.html;
44 }
45 }
46
47 server{
48 listen 8080;
49 server_name 42.96.184.84;
50
51 location /M00 {
52 root /home/fdfsdata/data;
53 ngx_fastdfs_module;
54 }
55
56 }
第1个server，是测试Nginx能正常启动。
第2个server，是监听8080端口，不带group的映射，到fdfs的数据目录。
带group的url访问
http://42.96.184.84:8080/group1/M00/00/00/KmC4VFYxy2OAAqGdAAAFrZvGHAA99.conf
Nginx配置
location /group1/M00 {
49 root /home/fdfsdata/data;
50 ngx_fastdfs_module;
51 }
/etc/fdfs/mod_fastdfs.conf 这个配置文件吧。
url_have_group_name = true（默认为false，改为true）
重启tracker、storage
重启Nginx
搞定啦~哦也~
十、小结
花费一天的时间，终于成功搭建了初步的fdfs环境。
Nginx+Fastdfs。

这个人写得有模有样，感觉比较可行啊~
我自己的，相对比较曲折，各种问题，但是都逐个解决了~
