分布式文件系统fastdfs_V5.09配置双tracker负载均衡
分布式文件系统fastdfs_V5.09配置双tracker负载均衡
环境准备
操作系统:
Centos 7
服务器：
IP：192.168.2.238
IP：192.168.2.239
软件包:
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:统一放置/home/soft目录，并且解压到当前目录
依赖包:
# 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、安装部署fastdfs(192.168.2.238,192.168.2.239)以及相关模块、依赖组件
1、安装部署fastdfs-5.09
#cd fastdfs-5.09 # ./make.sh #./make.sh install
2、编译安装部署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、安装libfastcommon插件
#cd /home/soft/libfastcommon-master/ #./make.sh #./make.sh install
4、创建相关目录以及链接文件
#mkdir -p /fastdfst/{tracker,storage,data1}
#ln -s /fastdfs/data M00
#ln -s /fastdfs/data1/data M01两台服务器（192.168.2.238,192.168.2.239）均以上操作
二、配置相关的conf文件
1、安装fastdfs后配置conf文件，在/etc/fdfs/目录下
# 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:

4、192.168.2.238、192.168.2.239启动相关服务
# /etc/init.d/fdfs_trackerd start # /etc/init.d/fdfs_storaged start # /usr/local/nginx/sbin/nginx # ss -tnlp (查看监听的tracker服务22124端口、storage服务23000端口、nginx服务81端口是否正常)
三、测试上传访问
1)在fastdfs服务器(192.168.2.239)上传239.jpg图片，并在通过返回的路径，在浏览器测试访问
[root@localhost ~]# fdfs_upload_file /etc/fdfs/client.conf /root/239.jpg
g1/M00/00/32/wKgC71kaaGqAbJDqAACKBbw6aXc203.jpg
访问测试
http://192.168.2.238:81/g1/M00/00/32/wKgC71kaaGqAbJDqAACKBbw6aXc203.jpg
http://192.168.2.239:81/g1/M00/00/32/wKgC71kaaGqAbJDqAACKBbw6aXc203.jpg
测试返回正常图片(详见下图)
2)在fastdfs服务器(192.168.2.238)上传238.jpg图片，并在通过返回的路径，在浏览器测试访问
[root@localhost ~]# fdfs_upload_file /etc/fdfs/client.conf /root/238.jpg
g1/M00/00/32/wKgC71kabh-AbUECAAC8W3Iysrc946.jpg
访问测试
http://192.168.2.238:81/g1/M00/00/32/wKgC71kabh-AbUECAAC8W3Iysrc946.jpg
http://192.168.2.239:81/g1/M00/00/32/wKgC71kabh-AbUECAAC8W3Iysrc946.jpg
测试返回正常图片(详见下图)
四、常见Q&A总结
1、fastdfs-nginx-module模块安装，make的时候会报一下错误，
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：编译安装nginx的fastdfs插件的头文件没有找到，由于编译nginx时候系统会到／usr/local/include，而编译安装fastdfs-nginx-module时则默认保存在了/usr/include目录。
解决办法：
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"
并且建立链接:
#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
重新编译，安装即可
2、在fastdfs_5.09,执行./make.sh 编译时提示编程
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、
解决方法:
# wget https://github.com/happyfish100/libfastcommon/archive/master.zip
# unzip master.zip
# cd libfastcommon-master/
# ./make.sh
# ./make.sh install
3、新增storage存储服务器后，无法启动
[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:启用了storage_ids.conf文件，来限制同一域或机房概念，必须把tracker和storage 的服务器ip必须在同一个域内
修改为/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)实际生产环境中出现这样的场景：当本身存在集群中只有一个tracker(本示例为10.x.x.3，并且当前为主leader)时，新加入一个tracker(如：本示例10.x.x.6为新加入的tracker)后，并且启动tracker服务，查看#tail -f /data/tracker/logs/trackerd.log 日志，报错如下:
[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

同时查看10.x.x.3 日志#tail -f /fastdfs/data/tracker/logs/trackerd.log，也会报以下错误:
[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:查看余大大的源码社区或谷歌搜索，是多tracker存在bug，github上更新了新版本V5.10已经修复这个问题。但经过验证该问题应该是新加入的tracker在集群同步时监测stroage同步情况存在差异时，有可能出现该问题。
解决方法：
1)、升级fastdfs版本至V5.10以上
2)、先重启所有的fdfs_stroaged服务，再建议先暂停当前主leader,然后清除新加入tracker 的/data/stracker/data/目录
下所有*.bat文件，再启动新加入的tracker服务，有可能出现如下信息(以下为示例实际操作中，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 #####这时说明新的tracker被选举为新的主leader
再新tracker被选举为新leader过程中，估计要等待1-2分钟左右，应该是监测并确认原会话中的老的leader不存在之后才确定选举新的leader。查看以上信息再启动老的leader(本示例中为10.x.x.3)tracker服务，正常情况会看到以下日志
[2017-05-24 02:39:00] INFO - file: tracker_service.c, line: 969, the tracker leader is 10.x.x.6:22122
。
至此说明新的tracker已经被集群中所识别，并且实现双tracker下负载以及故障转移。
五、模拟故障演练
1、当前主leader为192.168.2.238，tail tracker日志可以查看状态如下:
#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、模拟故障stop 192.168.2.238 tracker服务
# /etc/init.d/fdfs_trackerd stop Stopping fdfs_trackerd (via systemctl): [ OK ]
3、查看192.168.2.239，tracker日志,这时候192.168.2.239提升为新的leader,启动192.168.2.238的tracker自动变为备的
#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
#启动192.168.2.238 stracker服务，日志显示
# /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、测试上传是否正常和浏览图片是否正常
http://192.168.2.239:81/g1/M00/00/32/wKgC71kabh-AbUECAAC8W3Iysrc946.jpg
高可用情况下建议，访问存储服务器使用域名轮询，如:file.abc.com +haroxy 负载至后端两台stroage存储服务器
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
