FastDFS的实现
环境
centos7.1节点提供tracker和storage服务
centos7.2，centos7.3只提供storage服务
FastDFS的实现
fastdfs-5.0.11-1.el7.centos.x86_64.rpm #主程序
fastdfs-debuginfo-5.0.11-1.el7.centos.x86_64.rpm #debug先关的包
fastdfs-server-5.0.11-1.el7.centos.x86_64.rpm #提供tracker和storage节点的服务
fastdfs-tool-5.0.11-1.el7.centos.x86_64.rpm #工具包
libfastcommon-1.0.36-1.el7.centos.x86_64.rpm #下面四个是依赖的包
libfastcommon-devel-1.0.36-1.el7.centos.x86_64.rpm
libfdfsclient-5.0.11-1.el7.centos.x86_64.rpm
libfdfsclient-devel-5.0.11-1.el7.centos.x86_64.rpm
nginx-1.10.2-1.el7.centos.x86_64.rpm #使用nginx做为web界面需要用到的包
nginx-all-modules-1.10.2-1.el7.centos.noarch.rpm
nginx-filesystem-1.10.2-1.el7.centos.noarch.rpm
nginx-mod-http-geoip-1.10.2-1.el7.centos.x86_64.rpm
nginx-mod-http-image-filter-1.10.2-1.el7.centos.x86_64.rpm
nginx-mod-http-perl-1.10.2-1.el7.centos.x86_64.rpm
nginx-mod-http-xslt-filter-1.10.2-1.el7.centos.x86_64.rpm
nginx-mod-mail-1.10.2-1.el7.centos.x86_64.rpm
nginx-mod-stream-1.10.2-1.el7.centos.x86_64.rpm
1》安装
yum localinstall ./* #安装软件
cd /etc/fdfs/ ;ls #发现有很多示例
anti-steal.jpg client.conf.sample http.conf mime.types storage.conf.sample storage_ids.conf.sample tracker.conf.sample
2》在centos7.1节点上配置tracker节点
cd /etc/fdfs/
cp tracker.conf.sample tracker.conf.sample.bak
mv tracker.conf.sample tracker.conf
vim tracker.conf
base_path=/app/fastdfs/tracker #设置tracker的存储路径
store_group=shen #设置一个存储组，注意不能带任何符号，不然会出现端口启用不了
mkdir -pv /app/fastdfs/tracker #在centos7.1节点上创建tracker的数据目录
mkdir /app/fastdfs/storage #创建storage的存储目录
3》在centos7.2和7.3节点上只创建storage的存储目录
mkdir /app/fastdfs/storage -pv
4》在三个节点上对storage进行配置
cd /etc/fdfs/
cp storage.conf.sample storage.conf.sample.bak
mv storage.conf.sample storage.conf
vim storage.conf
group_name=shen
base_path=/app/fastdfs/storage #storage的基础路径，用于存储日志等
store_path0=/app/fastdfs/storage #storage的存储路径，这个必须设置，可以和上面的在同一个目录下
tracker_server=192.168.213.251:22122 #指明tracker主机
在centos7.1节点上启动tracker和storage服务
systemctl start fdfs_trackerd
systemctl start fdfs_storaged
ss -nltp #发现tracker监听的端口是22122，storage监听的端口是23000
在centos7.2和7.3节点上启动storage服务
systemctl start fdfs_storaged
ss -nlt #发现23000端口已经打开
5》配置客户端的配置文件，在centos7.1节点设置
cd /etc/fdfs/ ;ls
anti-steal.jpg http.conf storage.conf storage_ids.conf.sample tracker.conf.sample.bak
client.conf.sample mime.types storage.conf.sample.bak tracker.conf
cp client.conf.sample client.conf.bak
mv client.conf.bak client.conf
vim client.conf
base_path=/app/fastdfs/tracker
tracker_server=192.168.213.251:22122
fdfs_monitor /etc/fdfs/client.conf #可以查看存储节点的状态信息
6》文件的上传和查看操作
cd /etc/fdfs/ ;ls
anti-steal.jpg client.conf.sample mime.types storage.conf.sample.bak tracker.conf
client.conf http.conf storage.conf storage_ids.conf.sample tracker.conf.sample.bak
fdfs_upload_file /etc/fdfs/client.conf /app/flower.jpg #注意上传时要指明客户端的配置文件
shen/M00/00/00/wKjV-1o01sOAHG17AAAN9EUC0YY902.jpg
cd /app/fastdfs/storage/data/00/00/ ;ls #每个节点的此目录下都有这个文件，说明同步成功
wKjV-1o01sOAHG17AAAN9EUC0YY902.jpg
fdfs_file_info /etc/fdfs/client.conf shen/M00/00/00/wKjV-1o01sOAHG17AAAN9EUC0YY902.jpg #查看文件
source storage id: 0
source ip address: 192.168.213.251
file create timestamp: 2017-12-16 16:18:11
file size: 3572
file crc32: 1157812614 (0x4502D186)
fdfs_test /etc/fdfs/client.conf upload /root/anaconda-ks.cfg #上传测试
fdfs_upload_file /etc/fdfs/client.conf /root/anaconda-ks.cfg #上传文件
magedu/M00/00/00/rBIVB1oylFSADeGrAAAHXGXWizs514.cfg
fdfs_download_file /etc/fdfs/client.conf magedu/M00/00/00/rBIVB1oylFSADeGrAAAHXGXWizs514.cfg #下载文件到当前目录
FastDFS实现nginx代理
1》在centos7.1节点安装nginx的相关包，注意要安装nginx-1.10版本，不然可能没有ngx_fastdfs_module模块，如果之前已经安装nginx及相应的依赖包，最好先卸载了
cd /app
ls #将nginx-1.10.2版本的nginx及相应的依赖包下载到本地
nginx-1.10.2-1.el7.centos.x86_64.rpm #注意版本要统一都是1.10.2的版本
nginx-all-modules-1.10.2-1.el7.centos.noarch.rpm #下面这些都是nginx的依赖包
nginx-filesystem-1.10.2-1.el7.centos.noarch.rpm
nginx-mod-http-geoip-1.10.2-1.el7.centos.x86_64.rpm
nginx-mod-http-image-filter-1.10.2-1.el7.centos.x86_64.rpm
nginx-mod-http-perl-1.10.2-1.el7.centos.x86_64.rpm
nginx-mod-http-xslt-filter-1.10.2-1.el7.centos.x86_64.rpm
nginx-mod-mail-1.10.2-1.el7.centos.x86_64.rpm
nginx-mod-stream-1.10.2-1.el7.centos.x86_64.rpm
yum install ./nginx*
2》修改nginx的配置文件
vim /etc/nginx/nginx.conf
location /magedu/M00 { #表示匹配以 /magdu/M00开头的uri
root /app/fastdfs/storage; #指明数据存储的目录
ngx_fastdfs_module;
}
nginx
ngx_http_fastdfs_set pid=14594
ss -nlt
3》修改fastdfs_module配置文件的设置
vim /etc/fdfs/mod_fastdfs.conf
url_have_group_name = true #是否允许访问的url中包含组名
store_path0=/app/fastdfs/storage #指明storage节点存储数据的目录
tracker_server=172.18.21.107:22122 #指明tracker节点
group_name=magedu #指明组名
4》测试
fdfs_upload_file /etc/fdfs/client.conf /app/sunset.jpg #上传一个文件
magedu/M00/00/00/rBIVa1ozvNWAJLHkAAAKwLGLsZc035.jpg
访问如下网站就可以看到存储的图片
