1.安装LibFastCommon/FastDFS模块 执行节点 Tracker01、Tracker02、Storage01、Storage03、Storage04
[root@localhost fastDFS]# unzip libfastcommon-1.0.36.zip

解压后目录如下：
[root@localhost fastdfs-5.11]# ll [root@localhost libfastcommon-1.0.36]# ll 总用量 32 drwxr-xr-x. 2 root root117 4月5 2017 doc -rw-r--r--. 1 root root 8005 4月5 2017 HISTORY -rw-r--r--. 1 root root566 4月5 2017 INSTALL -rw-r--r--. 1 root root 1606 4月5 2017 libfastcommon.spec -rwxr-xr-x. 1 root root 3099 4月5 2017 make.sh drwxr-xr-x. 2 root root191 4月5 2017 php-fastcommon -rw-r--r--. 1 root root 2763 4月5 2017 README drwxr-xr-x. 3 root root 4096 1月17 11:21 src

安装C编译工具 gcc
[root@localhost fastdfs-5.11]# yum -y install gcc-c++

  • 安装装LibFastCommon
编译libfastcommon软件并安装
[root@localhost fastdfs-5.11]# ./make.sh&& ./make.sh install

为libcommon 创建软链接到/usr/local/lib目录下
[root@localhost fastdfs-5.11]# ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so [root@localhost fastdfs-5.11]# ln -s /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so [root@localhost fastdfs-5.11]# ln -s /usr/lib64/libfdfsclient.so /usr/local/lib/libfdfsclient.so [root@localhost fastdfs-5.11]# ln -s /usr/lib64/libfdfsclient.so /usr/lib/libfdfsclient.so

  • 安装FastDFS
    解压安装包
[root@localhost fastDFS]# unzip fastdfs-5.11.zip

进入解压目录并进行编译和安装
[root@localhost fastDFS]# cd fastdfs-5.11/ [root@localhost fastdfs-5.11]# ./make.sh&& ./make.sh install

【CentOS|CentOS 7.2搭建FastDFS 分布式文件系统，实现高可用集群】安装成功后，FastDFS会安装在/etc/fdfs目录下：
[root@localhost fastdfs-5.11]# ll /etc/fdfs/ 总用量 76 -rw-r--r--. 1 root root316 1月17 11:47 client.conf -rw-r--r--. 1 root root1461 1月17 11:25 client.conf.sample -rw-r--r--. 1 root root955 1月17 13:20 http.conf -rw-r--r--. 1 root root 31172 1月17 13:21 mime.types -rw-r--r--. 1 root root3716 1月17 12:57 mod_fastdfs.conf -rw-r--r--. 1 root root1278 1月17 11:40 storage.conf -rw-r--r--. 1 root root7927 1月17 11:25 storage.conf.sample -rw-r--r--. 1 root root105 1月17 11:25 storage_ids.conf.sample -rw-r--r--. 1 root root1356 1月17 11:34 tracker.conf -rw-r--r--. 1 root root7389 1月17 11:25 tracker.conf.sample

我们需要把这三个示例文件复制一份，去掉.sample
[root@localhost fdfs]# cp client.conf.sample client.conf [root@localhost fdfs]# cp storage.conf.sample storage.conf [root@localhost fdfs]# cp tracker.conf.sample tracker.conf

FastDFS安装结束
2.安装Tracker并实现节点信息配置
执行节点 Tracker01、Tracker02
  • 创建tracker工作目录
此目录用于保存tracker 的data和log
[root@localhost fdfs]# mkdir /opt/fastdfs_tracker

  • 配置tracker
配置 /etc/fdfs目录下tracker.conf
主要实现以下5个配置内容：
1.disabled=false 2.port=22122 #默认端口号 3.base_path=/opt/fastdfs_tracker #我刚刚创建的目录 4.http.server_port=8080 #默认端口是8080 5.store_lookup=0#采用轮询策略进行存储，0 轮询 1：始终定向到某个group 2：负载进行存储文件

完整tracker.conf 文件信息如下：
disabled=falsebind_addr= 0.0.0.0port=22122connect_timeout=30network_timeout=60base_path=/opt/fastdfs_trackermax_connections=512accept_threads=1work_threads=4min_buff_size = 8KBmax_buff_size = 128KBstore_lookup=0store_group=group2store_server=0store_path=0download_server=0reserved_storage_space = 10%log_level=inforun_by_group=run_by_user=allow_hosts=*sync_log_buff_interval = 10check_active_interval = 120thread_stack_size = 64KBstorage_ip_changed_auto_adjust = truestorage_sync_file_max_delay = 86400storage_sync_file_max_time = 300use_trunk_file = false slot_min_size = 256slot_max_size = 16MBtrunk_file_size = 64MBtrunk_create_file_advance = falsetrunk_create_file_time_base = 02:00trunk_create_file_interval = 86400trunk_create_file_space_threshold = 20Gtrunk_init_check_occupying = falsetrunk_init_reload_from_binlog = falsetrunk_compress_binlog_min_interval = 0use_storage_id = falsestorage_ids_filename = storage_ids.confid_type_in_filename = ipstore_slave_file_use_link = falserotate_error_log = falseerror_log_rotate_time=00:00rotate_error_log_size = 0log_file_keep_days = 0use_connection_pool = falseconnection_pool_max_idle_time = 3600http.server_port=8080http.check_alive_interval=30http.check_alive_type=tcphttp.check_alive_uri=/status.html

修改保存后创建软引用
[root@localhost fdfs]# ln -s /usr/bin/fdfs_storaged /usr/local/bin

  • 启动tracker，并加入开机启动项
[root@localhost fdfs]# service fdfs_trackerd start

将tracker加入开机启动项
[root@localhost fdfs]# echo "service fdfs_trackerd start" |tee -a /etc/rc.d/rc.local

3.安装Storage模块并实现配置 执行节点 Storage01、Storage02、Storage03、Storage04
  • 建立存储目录
在存储各节点建了两个目录fastdfs_storage_data,fastdfs_storage
[root@localhost opt]# mkdir fastdfs_storage [root@localhost opt]# mkdir fastdfs_storage_data [root@localhost opt]# ll 总用量 0 drwxr-xr-x. 4 root root 30 1月17 11:45 fastdfs_storage drwxr-xr-x. 3 root root 18 1月17 11:45 fastdfs_storage_data drwxr-xr-x. 4 root root 30 1月17 11:35 fastdfs_tracker

  • 修改存储节点目录下/etc/fdfs/storage.conf配置信息，具体如下：
disabled=false #启用配置文件 group_name=group1 #组名（第一组为 group1， 第二组为 group2） port=23000 #storage 的端口号,同一个组的 storage 端口号必须相同 base_path=/opt/fastdfs_storage #设置storage数据文件和日志目录 store_path0=/opt/fastdfs_storage_data #实际文件存储路径 store_path_count=1 #存储路径个数，需要和 store_path 个数匹配 tracker_server=192.168.43.70:22122 #tracker 服务器的 IP 地址和端口 tracker_server=192.168.43.70:22122 #多个 tracker 直接添加多条配置 http.server_port=8888 #设置 http 端口号

完整配置信息如下：
disabled=false group_name=group1 bind_addr= client_bind=true port=23000 connect_timeout=30 network_timeout=60 heart_beat_interval=30 stat_report_interval=60 base_path=/opt/fastdfs_storage max_connections=256 buff_size = 256KB accept_threads=1 work_threads=4 disk_rw_separated = true disk_reader_threads = 1 disk_writer_threads = 1 sync_wait_msec=50 sync_interval=0 sync_start_time=00:00 sync_end_time=23:59 write_mark_file_freq=500 store_path_count=1 store_path0=/opt/fastdfs_storage_data subdir_count_per_path=256 tracker_server=192.168.43.70:22122 tracker_server=192.168.43.71:22122 log_level=info run_by_group= run_by_user= allow_hosts=* file_distribute_path_mode=0 file_distribute_rotate_count=100 fsync_after_written_bytes=0 sync_log_buff_interval=10 sync_binlog_buff_interval=10 sync_stat_file_interval=300 thread_stack_size=512KB upload_priority=10 if_alias_prefix= check_file_duplicate=0 file_signature_method=hash key_namespace=FastDFS keep_alive=0 use_access_log = false rotate_access_log = false access_log_rotate_time=00:00 rotate_error_log = false error_log_rotate_time=00:00 rotate_access_log_size = 0 rotate_error_log_size = 0 log_file_keep_days = 0 file_sync_skip_invalid_record=false use_connection_pool = false connection_pool_max_idle_time = 3600 http.domain_name= http.server_port=8888

  • 启动Storage
    各节点配置好信息好之后，启动Storage
[root@localhost fdfs]# service fdfs_storaged start

启动后查看日志情况
[root@localhost fdfs]# fdfs_monitor /etc/fdfs/storage.conf [2018-01-20 16:56:48] DEBUG - base_path=/opt/fastdfs_storage, connect_timeout=30, network_timeout=60, tracker_server_count=2,

解压nginx和fastdfs-nginx-module
[root@localhost fdfs]# tar -zxvf nginx-1.10.3.tar.gz [root@localhost fdfs]# unzip fastdfs-nginx-module-master.zip

进入Nginx解压目录进行编译安装
[root@localhost nginx-1.10.3]# ./configure --prefix=/usr/local/nginx --add-module=/home/zhangyongliang/apps/fastdfs-nginx-module-master/src #解压后fastdfs-nginx-module所在的位置

安装成功后，nginx会安装在/usr/local/nginx,安装后查看
[root@localhost src]# ll /usr/local/nginx/ 总用量 8 drwx------. 2 nobody root6 1月17 13:23 client_body_temp drwxr-xr-x. 2 rootroot 4096 1月17 13:17 conf drwx------. 2 nobody root6 1月17 13:23 fastcgi_temp drwxr-xr-x. 2 rootroot40 1月17 13:17 html drwxr-xr-x. 2 rootroot58 1月17 13:49 logs -rw-r--r--. 1 rootroot 1156 1月17 13:29 nginx.conf drwx------. 2 nobody root6 1月17 13:23 proxy_temp drwxr-xr-x. 2 rootroot19 1月17 13:17 sbin drwx------. 2 nobody root6 1月17 13:23 scgi_temp drwx------. 2 nobody root6 1月17 13:23 uwsgi_temp

安装成功后，nginx尚未运行时，nginx文件夹没有临时文件夹，例如fastcgi_temp这些文件。


复制 fastdfs-nginx-module 源码中的配置文件到/etc/fdfs 目录， 并修改
[root@localhost src]# cp /usr/local/src/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/ [root@localhost src]# vi /etc/fdfs/mod_fastdfs.conf

(1)第1组 Storage 的 mod_fastdfs.conf 配置如下： connect_timeout=10 base_path=/opt/fastdfs_storage tracker_server=192.168.1.131:22122 tracker_server=192.168.1.132:22122 storage_server_port=23000 group_name=group1 url_have_group_name = true store_path0=/opt/fastdfs_storage_data group_count = 2 [group1] group_name=group1 storage_server_port=23000 store_path_count=1 store_path0=/opt/fastdfs_storage_data [group2] group_name=group2 storage_server_port=23000 store_path_count=1 store_path0=/opt/fastdfs_storage_data (2)第2组 Storage 的 mod_fastdfs.conf 配置与第一组配置只有 group_name 不同： group_name=group2

完整信息如下：

复制 FastDFS 安装目录的部分配置文件到/etc/fdfs 目录
[root@localhost conf]# pwd /home/zhangyongliang/apps/fastdfs-5.11/conf [root@localhost conf]# cp http.confmime.types/etc/fdfs/

创建M00至storage存储目录的符号连接：
ln-s/opt/fastdfs_storage_data/data/ /opt/fastdfs_storage_data/data/M00

配置 Nginx， 简洁版 nginx 配置样例
# vi /usr/local/nginx/conf/nginx.conf user root; worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 8888; server_name localhost; location ~/group([0-9])/M00 { #alias /fastdfs/storage/data; ngx_fastdfs_module; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } }

注意、 说明：

8888 端口值是要与/etc/fdfs/storage.conf 中的 http.server_port=8888 相对应，因为 http.server_port 默认为 8888,如果想改成 80，则要对应修改过来。

重新启动各节点的Nginx服务
[root@localhost conf]#/usr/local/nginx/sbin/nginx -s reload

4.文件上传测试 执行节点Tracker01、Tracker02

修改 Tracker 服务器中的客户端配置文件
# vi /etc/fdfs/client.conf base_path=/fastdfs/tracker tracker_server=192.168.43.70:22122 tracker_server=192.168.43.71:22122

执行如下文件上传命令
[root@localhost zhangyongliang]# fdfs_upload_file /etc/fdfs/client.conf P71022-205803.jpg group1/M00/00/00/wKgrSFpjC26AH1g2AAvUQrxXbkA557.jpg [root@localhost zhangyongliang]# fdfs_upload_file /etc/fdfs/client.conf P71022-205803.jpg group2/M00/00/00/wKgrSlpjC3aAARrXAAvUQrxXbkA048.jpg

进行2次上传后，发现文件被均衡分到2个group。
5.Tracker安装Nginx、 ngx_cache_purge 模块
  • 安装编译 Nginx 所需的依赖包
[root@localhost zhangyongliang]# yum install gcc gcc-c++ make automake autoconf libtool pcre pcre-devel zlib zlib-devel openssl openssl-devel

解压Nginx和ngx_cache_pure模块
[root@localhost apps]# tar ngx_cache_purge-2.3.tar.gz [root@localhost apps]# tar nginx-1.10.3.tar.gz

编译安装 Nginx（添加 ngx_cache_purge 模块）
[root@localhost apps]# cd nginx-1.13.0 [root@localhost nginx-1.13.0# ./configure --prefix=/usr/local/nginx --add-module=/usr/local/src/ngx_cache_purge-2.3 [root@localhost nginx-1.13.0]# make && make install

配置 Nginx， 设置负载均衡以及缓存
# vi /usr/local/nginx/conf/nginx.conf#usernobody; worker_processes1; #error_loglogs/error.log; #error_loglogs/error.lognotice; #error_loglogs/error.loginfo; #pidlogs/nginx.pid; events { worker_connections1024; }http { includemime.types; default_typeapplication/octet-stream; #log_formatmain'$remote_addr - $remote_user [$time_local] "$request" ' #'$status $body_bytes_sent "$http_referer" ' #'"$http_user_agent" "$http_x_forwarded_for"'; #access_loglogs/access.logmain; sendfileon; tcp_nopushon; #tcp_nopushon; #keepalive_timeout0; keepalive_timeout65; #gzipon; #设置缓存 server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 300m; proxy_redirect off; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 16k; proxy_buffers 4 64k; proxy_busy_buffers_size 128k; proxy_temp_file_write_size 128k; #设置缓存存储路径，存储方式，分别内存大小，磁盘最大空间，缓存期限 proxy_cache_path /opt/fastdfs_tracker/proxy_cache levels=1:2 keys_zone=http-cache:200m max_size=1g inactive=30d; proxy_temp_path /opt/fastdfs_tracker/tmp; #group1的服务设置 upstream fdfs_group1 { server 192.168.43.72:8888 weight=1 max_fails=2 fail_timeout=30s; server 192.168.43.73:8888 weight=1 max_fails=2 fail_timeout=30s; } #group2的服务设置 upstream fdfs_group2 { server 192.168.43.74:8888 weight=1 max_fails=2 fail_timeout=30s; server 192.168.43.75:8888 weight=1 max_fails=2 fail_timeout=30s; }server { listen8000; server_namelocalhost; #charset koi8-r; #access_loglogs/host.access.logmain; #group1的负载均衡配置 location /group1/M00 { proxy_next_upstream http_502 http_504 error timeout invalid_header; proxy_cache http-cache; proxy_cache_valid 200 304 12h; proxy_cache_key $uri$is_args$args; #对应group1的服务设置 proxy_pass http://fdfs_group1; expires 30d; } location /group2/M00 { proxy_next_upstream http_502 http_504 error timeout invalid_header; proxy_cache http-cache; proxy_cache_valid 200 304 12h; proxy_cache_key $uri$is_args$args; #对应group2的服务设置 proxy_pass http://fdfs_group2; expires 30d; } location ~/purge(/.*) { allow 127.0.0.1; allow 192.168.43.0/24; deny all; proxy_cache_purge http-cache $1$is_args$args; } location / { roothtml; indexindex.html index.htm; }#error_page404/404.html; # redirect server error pages to the static page /50x.html # error_page500 502 503 504/50x.html; location = /50x.html { roothtml; }# proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { #proxy_passhttp://127.0.0.1; #}# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # #location ~ \.php$ { #roothtml; #fastcgi_pass127.0.0.1:9000; #fastcgi_indexindex.php; #fastcgi_paramSCRIPT_FILENAME/scripts$fastcgi_script_name; #includefastcgi_params; #}# deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { #denyall; #} }# another virtual host using mix of IP-, name-, and port-based configuration # #server { #listen8000; #listensomename:8080; #server_namesomenamealiasanother.alias; #location / { #roothtml; #indexindex.html index.htm; #} #}# HTTPS server # #server { #listen443 ssl; #server_namelocalhost; #ssl_certificatecert.pem; #ssl_certificate_keycert.key; #ssl_session_cacheshared:SSL:1m; #ssl_session_timeout5m; #ssl_ciphersHIGH:!aNULL:!MD5; #ssl_prefer_server_cipherson; #location / { #roothtml; #indexindex.html index.htm; #} #}}

根据Nginx配置，创建对应目录下的文件夹
[root@localhost fastdfs_tracker]# mkdir proxy_cache tmp [root@localhost fastdfs_tracker]# ll 总用量 0 drwxr-xr-x. 2 rootroot 178 1月20 12:37 data drwxr-xr-x. 2 rootroot26 1月19 12:01 logs drwxr-xr-x. 7 nobody root51 1月19 19:35 proxy_cache drwxr-xr-x. 2 nobody root6 1月19 19:35 tmp

重启Nginx进行访问测试
重启 Nginx [root@localhost fastdfs_tracker]# /usr/local/nginx/sbin/nginx -s reload

前面直接通过访问 Storage 节点中的 Nginx 的文件

http://192.168.43.72:8888/group1/M00/00/00/wKgrSFpjC26AH1g2AAvUQrxXbkA557.jpg]

http://192.168.43.74:8888/group2/M00/00/00/wKgrSlpjC3aAARrXAAvUQrxXbkA048.jpg

现在可以通过 Tracker 中的 Nginx 来进行访问

(1)通过 Tracker1 中的 Nginx 来访问

http://192.168.43.70:8000/group1/M00/00/00/wKgrSFpjC26AH1g2AAvUQrxXbkA557.jpg

http://192.168.43.70:8000/group2/M00/00/00/wKgrSlpjC3aAARrXAAvUQrxXbkA048.jpg

(2)通过 Tracker2 中的 Nginx 来访问

http://192.168.43.71:8000/group1/M00/00/00/wKgrSFpjC26AH1g2AAvUQrxXbkA557.jpg

http://192.168.50.71:8000/group2/M00/00/00/wKgrSlpjC3aAARrXAAvUQrxXbkA048.jpg

6.构建Keepalive+Nginx 实现虚拟IP的代理 关于使用Keepalive+Nginx进行代理的环境安装，请参考本人此文：Keepalived+Nginx+Tomcat 实现高可用Web集群

本文不再做赘述说明

  • 启动Keepalvie+nginx Master主节点【192.168.43.101】
  • 启动Keepalvie+nginx BackUp备节点【192.168.43.102】


    修改2个节点Nginx下目录的nginx.conf的配置文件信息，添加如下内容

    主要内容为2个Tracker加入到Keepalive+nginx代理当中
upstream fastdfs_tracker { server 192.168.43.70:8000 weight=1 max_fails=2 fail_timeout=30s; server 192.168.43.71:8000 weight=1 max_fails=2 fail_timeout=30s; }

第二处修改是添加了一个location并且匹配规则是路径当中有fastdfs
location /fastdfs { root html; index index.html index.htm; proxy_pass http://fastdfs_tracker/; proxy_set_header Host $http_host; proxy_set_header Cookie $http_cookie; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; client_max_body_size 300m; }

完整配置代码如下：
#usernobody; worker_processes1; #error_loglogs/error.log; #error_loglogs/error.lognotice; #error_loglogs/error.loginfo; #pidlogs/nginx.pid; events { worker_connections1024; }http { includemime.types; default_typeapplication/octet-stream; #log_formatmain'$remote_addr - $remote_user [$time_local] "$request" ' #'$status $body_bytes_sent "$http_referer" ' #'"$http_user_agent" "$http_x_forwarded_for"'; #access_loglogs/access.logmain; sendfileon; #tcp_nopushon; #keepalive_timeout0; keepalive_timeout65; #gzipon; upstream fastdfs_tracker { server 192.168.43.70:8000 weight=1 max_fails=2 fail_timeout=30s; server 192.168.43.71:8000 weight=1 max_fails=2 fail_timeout=30s; } upstream tomcat{ server 192.168.43.103:8080 weight=1; server 192.168.43.104:8080 weight=1; }server { listen80; server_namelocalhost; #charset koi8-r; #access_loglogs/host.access.logmain; location / { proxy_pass http://tomcat; proxy_set_header X-NGINX "NGINX-1"; roothtml; indexindex.html index.htm; }#error_page404/404.html; # redirect server error pages to the static page /50x.html # error_page500 502 503 504/50x.html; location = /50x.html { roothtml; } location /fastdfs { root html; index index.html index.htm; proxy_pass http://fastdfs_tracker/; proxy_set_header Host $http_host; proxy_set_header Cookie $http_cookie; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; client_max_body_size 300m; }# proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { #proxy_passhttp://127.0.0.1; #}# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # #location ~ \.php$ { #roothtml; #fastcgi_pass127.0.0.1:9000; #fastcgi_indexindex.php; #fastcgi_paramSCRIPT_FILENAME/scripts$fastcgi_script_name; #includefastcgi_params; #}# deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { #denyall; #} }# another virtual host using mix of IP-, name-, and port-based configuration # #server { #listen8000; #listensomename:8080; #server_namesomenamealiasanother.alias; #location / { #roothtml; #indexindex.html index.htm; #} #}# HTTPS server # #server { #listen443 ssl; #server_namelocalhost; #ssl_certificatecert.pem; #ssl_certificate_keycert.key; #ssl_session_cacheshared:SSL:1m; #ssl_session_timeout5m; #ssl_ciphersHIGH:!aNULL:!MD5; #ssl_prefer_server_cipherson; #location / { #roothtml; #indexindex.html index.htm; #} #}}

修改之后，重新启动Keepalive+Nginx2台主备节点。
[root@nginx1 conf]#/usr/local/nginx/sbin/nginx -s reload

我们现在就用虚拟IP192.168.43.150来访问我们刚才上传的图片，只是注意在地址栏中要记得输入fastdfs（这是我们nginx.conf文件中location /fastdfs{}规则规定的）。如下图所示，发现，我们通过虚拟IP便可以访问我们上传的图片了。这样的好处是，对用户来说，只需要访问这个虚拟IP就可以了，不用关心FastDFS集群内部的转发机制。

CentOS|CentOS 7.2搭建FastDFS 分布式文件系统，实现高可用集群
文章图片
集群VIP访问截图.png
至此，分布式文件系统就搭建完成了，在通过Java访问时，只要在配置文件配置所有的Tracker节点IP信息就可以啦！
补充说明：
如果Tracker 服务、Storage服务、Nginx服务开机后没有自启动，请执行一下操作并进行重启
[root@localhost ~]# chkconfig--add fdfs_trackerd [root@localhost ~]# chkconfig--add fdfs_storaged

编辑目录下的/etc/rc.d/rc.local,内容如下：
#!/bin/bash # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES # # It is highly advisable to create own systemd services or udev rules # to run scripts during boot instead of using this file. # # In contrast to previous versions due to parallel execution during boot # this script will NOT be run after all other services. # # Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure # that this script will be executed during boot.touch /var/lock/subsys/local /usr/local/nginx/sbin/nginx

主要增加了Nginx的启动，之后进行文件授权，生效文件，重新启动系统
[root@localhost ~]# chmod+x /etc/rc.d/rc.local [root@localhost ~]# source /etc/rc.d/rc.local [root@localhost ~]# reboot
