下文給大家帶來分布式文件系統fastdfs_V5.09配置雙tracker負載均衡的詳細步驟和介紹，希望能夠給大家在實際運用中帶來一定的幫助，負載均衡涉及的東西比較多，理論也不多，網上有很多書籍，今天我們就用億速云在行業內累計的經驗來做一個解答。
分布式文件系統fastdfs_V5.09配置雙tracker負載均衡
環境準備
操作系統:
Centos 7
云服務器：
IP：192.168.2.238
IP：192.168.2.239
軟件包:
fastdfs-5.09.tar.gz
fastdfs-nginx-module_v1.16.tar.gz
libfastcommon-master
nginx-1.7.0.tar.gz
ngx_http_lower_upper_case-master
注:統一放置/home/soft目錄，并且解壓到當前目錄
依賴包:
# yum install gettext gettext-devel libXft libXft-devel libXpm libXpm-devel automake autoconf libXtst-devel gtk+-devel gcc gcc-c++zlib-devel libpng-devel gtk2-devel glib-devel pcre* -y
一、安裝部署fastdfs(192.168.2.238,192.168.2.239)以及相關模塊、依賴組件
1、安裝部署fastdfs-5.09
#cd fastdfs-5.09 # ./make.sh #./make.sh install
2、編譯安裝部署nginx
#cd nginx-1.7.0 #./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --add-module=/home/soft/fastdfs-nginx-module/src/ --add-module=/home/soft/ngx_http_lower_upper_case-master/ #make && make install
3、安裝libfastcommon插件
#cd /home/soft/libfastcommon-master/ #./make.sh #./make.sh install
4、創建相關目錄以及鏈接文件
#mkdir -p /fastdfst/{tracker,storage,data1}
#ln -s /fastdfs/data M00
#ln -s /fastdfs/data1/data M01兩臺服務器（192.168.2.238,192.168.2.239）均以上操作
二、配置相關的conf文件
1、安裝fastdfs后配置conf文件，在/etc/fdfs/目錄下
# ll /etc/fdfs/ client.conf client.conf.sample http.conf mime.types mod_fastdfs.conf mod_fastdfs.conf.bak storage.conf storage.conf.sample storage_ids.conf storage_ids.conf.sample tracker.conf tracker.conf.sample
2、192.168.2.238修改tracker.conf、 storage.conf、storage_ids.conf、mod_fastdfs.conf、nginx.conf各配置文件如下:
#vim /etc/fdfs/tracker.conf

# /etc/init.d/fdfs_trackerd start # /etc/init.d/fdfs_storaged start # /usr/local/nginx/sbin/nginx # ss -tnlp (查看監聽的tracker服務22124端口、storage服務23000端口、nginx服務81端口是否正常)
三、測試上傳訪問
1)在fastdfs服務器(192.168.2.239)上傳239.jpg圖片，并在通過返回的路徑，在瀏覽器測試訪問
[root@localhost ~]# fdfs_upload_file /etc/fdfs/client.conf /root/239.jpg
g1/M00/00/32/wKgC71kaaGqAbJDqAACKBbw6aXc203.jpg
訪問測試
http://192.168.2.238:81/g1/M00/00/32/wKgC71kaaGqAbJDqAACKBbw6aXc203.jpg
http://192.168.2.239:81/g1/M00/00/32/wKgC71kaaGqAbJDqAACKBbw6aXc203.jpg
測試返回正常圖片(詳見下圖)
2)在fastdfs服務器(192.168.2.238)上傳238.jpg圖片，并在通過返回的路徑，在瀏覽器測試訪問
[root@localhost ~]# fdfs_upload_file /etc/fdfs/client.conf /root/238.jpg
g1/M00/00/32/wKgC71kabh-AbUECAAC8W3Iysrc946.jpg
訪問測試

http://192.168.2.239:81/g1/M00/00/32/wKgC71kabh-AbUECAAC8W3Iysrc946.jpg
測試返回正常圖片(詳見下圖)
四、常見Q&A總結
1、fastdfs-nginx-module模塊安裝，make的時候會報一下錯誤，
root/fastdfs-nginx-module/src//common.c:21:25: fatal error: fdfs_define.h: No such file or directory
#include "fdfs_define.h"
^
compilation terminated.
make[1]: *** [objs/addon/src/ngx_http_fastdfs_module.o] Error 1
原因：編譯安裝nginx的fastdfs插件的頭文件沒有找到，由于編譯nginx時候系統會到／usr/local/include，而編譯安裝fastdfs-nginx-module時則默認保存在了/usr/include目錄。
解決辦法：
vim /root/fastdfs-nginx-module/src/config
CORE_INCS="$CORE_INCS /usr/local/include/fastdfs /usr/local/include/fastcommon/"
CORE_LIBS="$CORE_LIBS -L/usr/lib -lfastcommon -lfdfsclient"
并且建立鏈接:
#ln -s /usr/include/fast* /usr/local/include/
#ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so
#ln -s /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so
#ln -s /usr/lib64/libfdfsclient.so /usr/local/lib/libfdfsclient.so
#ln -s /usr/lib64/libfdfsclient.so /usr/lib/libfdfsclient.so
重新編譯，安裝即可
2、在fastdfs_5.09,執行./make.sh 編譯時提示編程
cc -Wall -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE -g -O -DDEBUG_FLAG -c -o ../common/fdfs_global.o ../common/fdfs_global.c -I../common -I../tracker -I/usr/include/fastcommon
../common/fdfs_global.c:20:20: fatal error: logger.h: No such file or directory
#include "logger.h"
^
compilation terminated.
make: *** [../common/fdfs_global.o] Error 1、
解決方法:
# wget https://github.com/happyfish300/libfastcommon/archive/master.zip
# unzip master.zip
# cd libfastcommon-master/
# ./make.sh
# ./make.sh install
3、新增storage存儲服務器后，無法啟動
[2017-05-12 17:09:40] ERROR - file: tracker_proto.c, line: 48, server: 192.168.2.239:22124, response status 2 != 0
[2017-05-12 17:09:40] CRIT - file: storage_func.c, line: 1886, get my server id from tracker server fail, errno: 2, error info: No such file or directory
原因:啟用了storage_ids.conf文件，來限制同一域或機房概念，必須把tracker和storage 的服務器ip必須在同一個域內
修改為/etc/fdfs/storage_ids.conf如下：
[root@localhost fdfs]# cat storage_ids.conf
# <id> <group_name> <ip_or_hostname>
# 100001 group1 192.168.0.196
# 100002 group1 192.168.0.116
200050 g1 192.168.2.239
200051 g1 192.168.2.238
4、(fastdfs版本v5.09)實際生產環境中出現這樣的場景：當本身存在集群中只有一個tracker(本示例為10.x.x.3，并且當前為主leader)時，新加入一個tracker(如：本示例10.x.x.6為新加入的tracker)后，并且啟動tracker服務，查看#tail -f /data/tracker/logs/trackerd.log 日志，報錯如下:
[2017-05-19 23:04:33] ERROR - file: tracker_mem.c, line: 4277, get sys files from other trackers fail, errno: 2
[2017-05-19 23:04:52] ERROR - file: tracker_proto.c, line: 48, server: 10.x.x.3:22122, response status 5 != 0
[2017-05-19 23:04:52] INFO - file: tracker_mem.c, line: 4213, sys files loaded from tracker server 10.x.x.3:22122

同時查看10.x.x.3 日志#tail -f /fastdfs/data/tracker/logs/trackerd.log，也會報以下錯誤:
[2017-05-19 23:01:54] ERROR - file: tracker_service.c, line: 2008, client ip: 10.x.x.6, read bytes: 229 != expect bytes: 230

原因:查看余大大的源碼社區或谷歌搜索，是多tracker存在bug，github上更新了新版本V5.10已經修復這個問題。但經過驗證該問題應該是新加入的tracker在集群同步時監測stroage同步情況存在差異時，有可能出現該問題。
解決方法：
1)、升級fastdfs版本至V5.10以上
2)、先重啟所有的fdfs_stroaged服務，再建議先暫停當前主leader,然后清除新加入tracker 的/data/stracker/data/目錄
下所有*.bat文件，再啟動新加入的tracker服務，有可能出現如下信息(以下為示例實際操作中，提示的信息):
[2017-05-24 02:38:34] ERROR - file: tracker_mem.c, line: 596, in the file "/data/tracker/data/storage_groups_new.dat", item "group_count" is not found

[2017-05-24 02:38:59] INFO - file: tracker_relationship.c, line: 401, I am the new tracker leader 10.x.x.6:22122 #####這時說明新的tracker被選舉為新的主leader
再新tracker被選舉為新leader過程中，估計要等待1-2分鐘左右，應該是監測并確認原會話中的老的leader不存在之后才確定選舉新的leader。查看以上信息再啟動老的leader(本示例中為10.x.x.3)tracker服務，正常情況會看到以下日志
[2017-05-24 02:39:00] INFO - file: tracker_service.c, line: 969, the tracker leader is 10.x.x.6:22122
。
至此說明新的tracker已經被集群中所識別，并且實現雙tracker下負載以及故障轉移。
五、模擬故障演練
1、當前主leader為192.168.2.238，tail tracker日志可以查看狀態如下:
#tail -f /fastdfs/tracker/log/tracker.log [2017-05-18 17:13:42] INFO - file: tracker_relationship.c, line: 401, I am the new tracker leader 192.168.2.238:22124
2、模擬故障stop 192.168.2.238 tracker服務
# /etc/init.d/fdfs_trackerd stop Stopping fdfs_trackerd (via systemctl): [ OK ]
3、查看192.168.2.239，tracker日志,這時候192.168.2.239提升為新的leader,啟動192.168.2.238的tracker自動變為備的
#tail -f /fastdfs/tracker/log/tracker.log [2017-05-18 17:17:58] INFO - file: tracker_relationship.c, line: 401, I am the new tracker leader 192.168.2.239:22124
#啟動192.168.2.238 stracker服務，日志顯示
# /etc/init.d/fdfs_trackerd start #tail -f /fastdfs/tracker/log/tracker.log [2017-05-18 17:20:44] INFO - FastDFS v5.09, base_path=/fastdfs/tracker, run_by_group=, run_by_user=, connect_timeout=30s, network_timeout=60s, port=22124, bind_addr=192.168.2.238, max_connections=256, accept_threads=1, work_threads=4, min_buff_size=8192, max_buff_size=131072, store_lookup=2, store_group=, store_server=2, store_path=0, reserved_storage_space=10.00%, download_server=0, allow_ip_count=-1, sync_log_buff_interval=10s, check_active_interval=120s, thread_stack_size=64 KB, storage_ip_changed_auto_adjust=1, storage_sync_file_max_delay=86400s, storage_sync_file_max_time=300s, use_trunk_file=0, slot_min_size=256, slot_max_size=16 MB, trunk_file_size=64 MB, trunk_create_file_advance=0, trunk_create_file_time_base=02:00, trunk_create_file_interval=86400, trunk_create_file_space_threshold=20 GB, trunk_init_check_occupying=0, trunk_init_reload_from_binlog=0, trunk_compress_binlog_min_interval=0, use_storage_id=1, id_type_in_filename=ip, storage_id_count=2, rotate_error_log=0, error_log_rotate_time=00:00, rotate_error_log_size=0, log_file_keep_days=0, store_slave_file_use_link=0, use_connection_pool=0, g_connection_pool_max_idle_time=3600s [2017-05-18 17:21:06] INFO - file: tracker_relationship.c, line: 383, selecting leader...

4、測試上傳是否正常和瀏覽圖片是否正常
http://192.168.2.239:81/g1/M00/00/32/wKgC71kabh-AbUECAAC8W3Iysrc946.jpg
高可用情況下建議，訪問存儲服務器使用域名輪詢，如:file.abc.com +haroxy 負載至后端兩臺stroage存儲服務器
acl fileserver hdr_beg(host) -i file.abc.com use_backend file.abc.com if fileserver backend file.abc.com mode http option forwardfor option httplog balance roundrobin #reqirep ^Host:\ www.1card1.cn Host:\ file.abc.com server db1 192.168.2.238:81 cookie files check server db2 192.168.2.239:81 cookie files check
