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
系统软件说明:

4、安装nginx和fastdfs-nginx-module
下载nginx module
$ wget https://github.com/happyfish100/fastdfs-nginx-module/archive/V1.20.tar.gz $ cp /opt/fastdfs/fastdfs-nginx-module-1.20/src/mod_fastdfs.conf /etc/fdfs
安装nginx
$ yum install nginx -y # 查看版本及编译参数 $ nginx -v $ nginx -V
添加nginx module
wget http://nginx.org/download/nginx-1.12.2.tar.gz $ tar -zxvf nginx-1.12.2.tar.gz $ cd nginx-1.12.2/ $ ./configure --prefix=/usr/share/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/lib/nginx/tmp/client_body --http-proxy-temp-path=/var/lib/nginx/tmp/proxy --http-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi --http-scgi-temp-path=/var/lib/nginx/tmp/scgi --pid-path=/run/nginx.pid --lock-path=/run/lock/subsys/nginx --user=nginx --group=nginx --with-file-aio --with-ipv6 --with-http_auth_request_module --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module=dynamic --with-http_image_filter_module=dynamic --with-http_geoip_module=dynamic --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_slice_module --with-http_stub_status_module --with-http_perl_module=dynamic --with-mail=dynamic --with-mail_ssl_module --with-pcre --with-pcre-jit --with-stream=dynamic --with-stream_ssl_module --with-google_perftools_module --with-debug --with-cc-opt=‘-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic‘ --with-ld-opt=‘-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-E‘ --add-module=/opt/fastdfs/fastdfs-nginx-module-1.20/src/ $ 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=192.168.0.1:22122 # tracker服务器IP和端口 tracker_server=192.168.0.2:22122 # 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 8888; ## 该端口为storage.conf中的http.server_port相同 server_name localhost; location ~/group[0-9]/ { root /data/fastdfs; ngx_fastdfs_module; } error_page 500 502 503 504 /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="$CORE_INCS /usr/include/fastdfs /usr/include/fastcommon/" 然后重新./configure && make,就可以了
5、配置文件访问的负载均衡和高可用
在192.168.0.100和101上安装nginx、keepalived
yum install -y nginx keepalived
nginx的配置文件如下:
upstream fdfs_group01 { server 192.168.0.10:8888 weight=1 max_fails=2 fail_timeout=30s; server 192.168.0.11:8888 weight=1 max_fails=2 fail_timeout=30s; } server { listen 80; server_name localhost; location /group01{ proxy_next_upstream http_502 http_504 error timeout invalid_header; proxy_pass http://fdfs_group01; expires 30d; } }
keepalived配置文件如下:
global_defs { router_id LVS_DEVEL } vrrp_script chk_ngx { script "/etc/keepalived/check_nginx.sh" interval 2 weight -5 fall 3 rise 2 } vrrp_instance VI_1 { interface eno16777984 state MASTER priority 100 virtual_router_id 11 advert_int 1 authentication { auth_type PASS auth_pass 1111 } unicast_src_ip 192.168.0.100 unicast_peer { 192.168.0.101 } virtual_ipaddress { 192.168.0.200 } track_script { chk_ngx } notify_master "/etc/keepalived/notify.sh master" notify_backup "/etc/keepalived/notify.sh backup" notify_fault "/etc/keepalived/notify.sh fault" }
check_nginx.sh
#!/bin/bash counter=$(ps -C nginx --no-heading|wc -l) if [ "${counter}" = "0" ]; then exit 1 else exit 0 fi
OK,以上就是所有的安装步骤及相关配置。
