Centos7配置fastdfs和nginx分布式文件存储系统实现过程解析

1、安装libfastcommon-1.0.43，安装包可以在大佬的https://github.com/happyfish100/libfastcommon/releases下载

[root@localhost Downloads]# tar -zxvf libfastcommon-1.0.43.tar.gz

# 解压后进入目录进行编译并安装
[root@localhost libfastcommon-1.0.43]#cd libfastcommon-1.0.43
[root@localhost libfastcommon-1.0.43]#make
[root@localhost libfastcommon-1.0.43]#make install

注意：libfastcommon安装好后会在/usr/lib64 目录下生成 libfastcommon.so 库文件；由于FastDFS程序引用usr/lib目录所以需要将/usr/lib64下的库文件拷贝至/usr/lib下

cp /usr/lib64/libfastcommon.so /usr/lib

2、安装fastdfs，安装包可以在大佬的https://github.com/happyfish100/fastdfs/releases下载

#解压到当前目录
tar -zxvf fastdfs-6.06.tar.gz

# 进入到目录进行编译与安装
make.sh
make.sh install

安装成功后，将/conf下的文件复制到/etc/fdfs中

[root@localhost conf]# ll
total 92
-rw-rw-r--. 1 root root 23981 Dec 31 07:36 anti-steal.jpg
-rw-rw-r--. 1 root root 1909 Dec 31 07:36 client.conf

[root@localhost conf]# cd ..
[root@localhost fastdfs-6.06]# cp /conf/* /etc/fdfs

-rw-r--r--. 1 root root 10246 Jun 21 02:15 storage.conf.sample
-rw-r--r--. 1 root root 620 Jun 21 02:16 storage_ids.conf
-rw-r--r--. 1 root root 620 Jun 21 02:15 storage_ids.conf.sample
-rw-r--r--. 1 root root 9129 Jun 21 02:18 tracker.conf
-rw-r--r--. 1 root root 9138 Jun 21 02:15 tracker.conf.sample
[root@localhost fastdfs-6.06]#

3、配置和启动tracker

# 进入/etc/fdfs目录中
cd /etc/fdfs

# 拷贝一份新的tracker配置文件
cp tracker.conf.sample tracker.conf

#修改tracker.conf ; vim tracker.conf
# /home/fastdfs用于存放tracker的data和log
base_path=/home/yuqing/fastdfs 改为: base_path=/home/fastdfs
http.server_port 改为： 80

# 启动tracker
/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart

4、配置和启动storage

# 进入/etc/fdfs目录中
cd /etc/fdfs

# 拷贝一份新的tracker配置文件
cp storage.conf.sample storage.conf

# 修改storage.conf ; vim storage.conf
group_name=group1 #配置组名
base_path=/home/yuqing/fastdfs 改为: base_path=/home/fastdfs

#store存放文件的位置(store_path)
store_path0=/home/yuqing/fastdfs 改为： store_path0=/home/fdfs_storage
#如果有多个挂载磁盘则定义多个store_path，如下
#store_path1=.....
#store_path2=......

#配置tracker服务器:IP
tracker_server=192.168.172.20:22122
#如果有多个则配置多个tracker
#tracker_server=192.168.101.4:22122

#配置http端口,使用默认端口
http.server_port=8888

#启动storage， 运行命令如下：
/usr/bin/fdfs_storaged /etc/fdfs/storage.conf restart

#启动完成后进入 /home/fdfs_storage/data 目录下，显示目录如下
[root@localhost home]# cd fdfs_storage/
[root@localhost fdfs_storage]# ls
data
[root@localhost fdfs_storage]# cd data/
[root@localhost data]# ls

[root@localhost data]#

5、使用fastdfs自带工具测试上传文件

# 切换目录到 /etc/fdfs/ 目录下
cd /etc/fdfs

# 拷贝一份新的client配置文件
cp client.conf.sample client.conf

# 修改client.conf ; vim client.conf
base_path = /home/fastdfs
tracker_server = 192.168.52.133:22122
#tracker_server = 192.168.0.197:22122

#进行上传文件的测试，运行如下：
/usr/bin/fdfs_test /etc/fdfs/client.conf upload wyc01.jpg

#结果：
[youth@localhost Pictures]$ /usr/bin/fdfs_test /etc/fdfs/client.conf upload wyc01.jpg
This is FastDFS client test program v6.06

注意：http://192.168.52.133/group1/M00/00/00/wKg0hV7uaXyALZfuAABDP6pWIGE814.jpg就是刚才上传图片的链接，但是现在没有整合nginx，所以无法通过http访问

6、fastdfs和nginx整合

①安装fastdfs-nginx-module，安装包可以在大佬的https://github.com/happyfish100/fastdfs-nginx-module/releases下载

#解压
tar -zxvf fastdfs-nginx-module_v1.16.tar.gz

# 进入到目录里修改conf配置
cd /usr/local/fastdfs-nginx-module/src/

vim conf

 HTTP_MODULES="$HTTP_MODULES ngx_http_fastdfs_module"
 NGX_ADDON_SRCS="$NGX_ADDON_SRCS $ngx_addon_dir/ngx_http_fastdfs_module.c"
 # 只修改这里，把local删除
 CORE_INCS="$CORE_INCS /usr/include"
 CORE_LIBS="$CORE_LIBS -lfastcommon -lfdfsclient"
 CFLAGS="$CFLAGS -D_FILE_OFFSET_BITS=64 -DFDFS_OUTPUT_CHUNK_SIZE='256*1024' -DFDFS_MOD_CONF_FILENAME='\"/etc/fdfs/mod_fastdfs.conf\"'"

②将fastdfs-nginx-module/src下的mod_fastdfs.conf拷贝至/etc/fdfs/下

　　cp mod_fastdfs.conf /etc/fdfs/

　③并修改 /etc/fdfs/mod_fastdfs.conf 的内容；vi /etc/fdfs/mod_fastdfs.conf

base_path=/home/fastdfs
tracker_server=192.168.172.20:22122
#tracker_server=192.168.172.20:22122 #(多个tracker配置多行)
url_have_group_name=true #url中包含group名称
store_path0=/home/fdfs_storage #指定文件存储路径（上面配置的store路径）

7、安装nginx

# nginx官网上有安装包，可以直接下载
# 解压
tar -zxvf nginx-1.8.0.tar.gz

# 进入目录，配置命令
# --prefix是nginx的安装路径
# --add-module是fastdfs-nginx-module解压后的文件路径
./configure \
--prefix=/usr/local/nginx \
--pid-path=/var/run/nginx/nginx.pid \
--lock-path=/var/lock/nginx.lock \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--with-http_gzip_static_module \
--http-client-body-temp-path=/var/temp/nginx/client \
--http-proxy-temp-path=/var/temp/nginx/proxy \
--http-fastcgi-temp-path=/var/temp/nginx/fastcgi \
--http-uwsgi-temp-path=/var/temp/nginx/uwsgi \
--http-scgi-temp-path=/var/temp/nginx/scgi \
--add-module=/usr/local/fastdfs-nginx-module/src# 编译并安装
make && make install# 复制nginx-1.19.0/conf配置文件夹（解压后的nginx）里面的两个文件到/etc/fdfs
cp http.conf mime.types /etc/fdfs/

注意:上边将临时文件目录指定为/var/temp/nginx，需要在/var下创建temp及nginx目录；我指定了pid-path，所以也要在/var/run文件夹下创建一个nginx,然后在nginx文件夹下创建一个nginx.pid，否则启动nginx时会报错nginx: [emerg] open() "/var/run/nginx/nginx.pid" failed (2: No such file or directory)，还是建议不指定了，这个坑太深了

8、修改nginx配置文件

server {
  listen  80;
  #server_name localhost;
  server_name 192.168.52.133;

  #charset koi8-r;

  #access_log logs/host.access.log main;

  location ~/group([1~9])/M00/{
   root /home/fdsf_storage/data;
   ngx_fastdfs_module;
  }

  location / {
   root html;
   index index.html index.htm;
  }

9、启动nginx，因为nginx默认是80端口，确保80端口没有被占用，如果占用就kill掉；确保防火墙firewall允许外部设备访问服务器

/use/local/nginx/sbin/nginx

[root@localhost fdfs]# ps -ef | grep nginx
root 7466 1 0 03:12 ? 00:00:00 nginx: master process nginx
nobody 7590 7466 0 03:21 ? 00:00:00 nginx: worker process
root 8514 2806 0 04:17 pts/0 00:00:00 grep --color=auto nginx
[root@localhost fdfs]#

10、通过外部设备访问fastdfs文件系统的图片
