一、基本模块及高可用架构
FastDFS 是余庆老师开发的一个开源的高性能分布式文件系统(DFS)。 它的主要功能包括:文件存储,文件同步和文件访问,以及高容量和负载平衡。
FastDFS 系统有三个角色:跟踪服务器(Tracker Server)、存储服务器(Storage Server)和客户端(Client)。
- Tracker Server: 跟踪服务器,主要做调度工作,起到均衡的作用;负责管理所有的storage server和group,每个storage在启动后会连接 Tracker,告知自己所属 group 等信息,并保持周期性心跳。多个Tracker之间是对等关系,不存在单点故障。
- Storage Server: 存储服务器,主要提供容量和备份服务;以 group 为单位,每个 group 内可以有多台 storage server,组内的storage server上的数据互为备份。
- Client:客户端,上传下载数据的服务器
模块之间的主要关系如下:
下图是实现统一的对外下载访问入口的高可用架构,其中所有的Nginx只做下载用途,上传通过tracker进行上传。
二、环境准备工作

$ make
$ cp objs/nginx /usr/sbin/nginx
$ systemctl enable nginx
$ systemctl restart nginx
查看插件是否安装成功:
$ nginx -V
配置nginx访问
$ vim /etc/fdfs/mod_fastdfs.conf
#需要修改的内容如下
tracker_server=192.168.0.1: # tracker服务器IP和端口
tracker_server=192.168.0.2: # tracker服务器IP和端口
url_have_group_name=true
base_path=/data/fastdfs
store_path0=/data/fastdfs
#配置nginx.config
$ vim /etc/nginx/nginx.conf
#增加如下内容
server {
listen ; ## 该端口为storage.conf中的http.server_port相同
server_name localhost;
location ~/group[-]/ {
root /data/fastdfs;
ngx_fastdfs_module;
}
error_page /50x.html;
location = /50x.html {
root html;
}
}
#测试下载,用外部浏览器访问刚才已传过的文件,引用返回的ID
http://192.168.0.10:8888/group1/M00/00/00/wKgAQ1pysxmAaqhAAA76tz-dVgg.tar.gz
#弹出下载则目前nginx已经OK
注:
在nginx的构建中会遇到不少的报错,具体如下:
- ./configure: error: the Google perftools module requires the Google perftools library. You can either do not enable the module or install the library.
解决方法如下:
$ yum install gperftools -y
- /configure: error: the HTTP rewrite module requires the PCRE library.
解决方法如下:
$ yum -y install pcre pcre-devel
- ./configure: error: the HTTP cache module requires md5 functions from OpenSSL library. You can either disable the module by using --without-http-cache option, or install the OpenSSL library into the system, or build the OpenSSL library statically from the source with nginx by using --with-http_ssl_module --with-openssl= options.
解决方法如下:
$ yum -y install openssl openssl-devel
- ./configure: error: the HTTP gzip module requires the zlib library. You can either disable the module by using –without-http_gzip_module option, or install the zlib library into the system, or build the zlib library statically from the source with nginx by using –with-zlib= option.
解决方法如下:
$ yum install -y zlib-devel
- ./configure: error: the HTTP XSLT module requires the libxml2/libxslt libraries. You can either do not enable the module or install the libraries.
解决方法如下:
$ yum -y install libxml2 libxml2-dev
$ yum -y install libxslt-devel
- ./configure: error: the HTTP image filter module requires the GD library. You can either do not enable the module or install the libraries.
解决方法如下:
$ yum -y install gd-devel
- ./configure: error: perl module ExtUtils::Embed is required
解决方法如下:
$ yum -y install perl-devel perl-ExtUtils-Embed
- ./configure: error: the GeoIP module requires the GeoIP library. You can either do not enable the module or install the library.
解决方法如下:
$ yum -y install GeoIP GeoIP-devel GeoIP-data
- 在make过程中会出现一个报错:/usr/include/fastdfs/fdfs_define.h:15:27: fatal error: common_define.h: No such file or directory
解决方法如下:
修改fastdfs-nginx-module-1.20/src/config文件,修改如下:
ngx_module_incs="/usr/include/fastdfs /usr/include/fastcommon/"
CORE_INCS="$CORE_INCS /usr/include/fastdfs /usr/include/fastcommon/"
然后重新./configure && make,就可以了
5、配置文件访问的负载均衡和高可用
在192.168.0.100和101上安装nginx、keepalived
yum install -y nginx keepalived
nginx的配置文件如下:
upstream fdfs_group01 {
server 192.168.0.10: weight= max_fails= fail_timeout=30s;
server 192.168.0.11: weight= max_fails= fail_timeout=30s;
}
server {
listen ;
server_name localhost;
location /group01{
proxy_next_upstream http_502 http_504 error timeout invalid_header;
proxy_pass http://fdfs_group01;
expires 30d;
}
}
keepalived配置文件如下:
global_defs {
router_id LVS_DEVEL
} vrrp_script chk_ngx {
script "/etc/keepalived/check_nginx.sh"
interval
weight -
fall
rise
} vrrp_instance VI_1 {
interface eno16777984
state MASTER
priority
virtual_router_id
advert_int
authentication {
auth_type PASS
auth_pass
} unicast_src_ip 192.168.0.100 unicast_peer {
192.168.0.101
} virtual_ipaddress {
192.168.0.200
} track_script {
chk_ngx
}
notify_master "/etc/keepalived/notify.sh master"
notify_backup "/etc/keepalived/notify.sh backup"
notify_fault "/etc/keepalived/notify.sh fault"
}
check_nginx.sh
#!/bin/bash counter=$(ps -C nginx --no-heading|wc -l)
if [ "${counter}" = "" ]; then
exit
else
exit
fi
OK,以上就是所有的安装步骤及相关配置。
