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

# 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.confbase_path = /home/fastdfstracker_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 v6.06Copyright (C) 2008, Happy Fish / YuQingFastDFS may be copied only under the terms of the GNU GeneralPublic License V3, which may be found in the FastDFS source kit.Please visit the FastDFS Home Page http://www.fastken.com/ for more detail.[2020-06-21 03:54:35] DEBUG - base_path=/home/fastdfs, connect_timeout=5, 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: 0tracker_query_storage_store_list_without_group:server 1. group_name=, ip_addr=192.168.52.133, port=23000group_name=group1, ip_addr=192.168.52.133, port=23000storage_upload_by_filenamegroup_name=group1, remote_filename=M00/00/00/wKg0hV7uaXyALZfuAABDP6pWIGE814.jpgsource ip address: 192.168.52.133file timestamp=2020-06-21 03:54:36file size=17215file crc32=2857771105example file url: http://192.168.52.133/group1/M00/00/00/wKg0hV7uaXyALZfuAABDP6pWIGE814.jpgstorage_upload_slave_by_filenamegroup_name=group1, remote_filename=M00/00/00/wKg0hV7uaXyALZfuAABDP6pWIGE814_big.jpgsource ip address: 192.168.52.133file timestamp=2020-06-21 03:54:36file size=17215file crc32=2857771105example file url: http://192.168.52.133/group1/M00/00/00/wKg0hV7uaXyALZfuAABDP6pWIGE814_big.jpg[youth@localhost Pictures]$注意：http://192.168.52.133/group1/M00/00/00/wKg0hV7uaXyALZfuAABDP6pWIGE814.jpg就是刚才上传图片的链接，但是现在没有整合nginx，所以无法通过http访问
6、fastdfs和nginx整合
①安装fastdfs-nginx-module，安装包可以在大佬的https://github.com/happyfish100/fastdfs-nginx-module/releases下载
#解压tar -zxvf fastdfs-nginx-module_v1.16.tar.gz# 进入到目录里修改conf配置cd /usr/local/fastdfs-nginx-module/src/vim conf HTTP_MODULES="$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/fdfscp 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 {listen80;#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]#
