在前面一篇文章中介绍了fastfds的简单安装和文件上传功能(见 http://www.linuxidc.com/Linux/2012-08/67032.htm ),以及使用fastdfs自带的http下载功能等;本文中将介绍如何使用fastdfs-apache-module模块整合fastdfs和apahce;整合完毕后,客户端访问apache,apache根据配置,使用fastdfs连接tracker查询相应组内可用的stroage服务器,最后完成http请求的重定向!因而建议在每台storage服务器上都配置fastdfs和apahce的整合,各个组间配置相应的虚拟主机,还可以在前端使用nginx做负载均衡来分配用户的请求。在开始之前,需要在storage服务器上安装好apache,本例中使用编译方式安装!
1:下载fastdfs-apache-module源码
- [root@www ~]# wget http://fastdfs.googlecode.com/files/fastdfs-apache-module_v1.08.tar.gz
- [root@www ~]# tar -zxvf fastdfs-apache-module_v1.08.tar.gz
- [root@www ~]# cd fastdfs-apache-module/src/
2:查看apache的编译路径和参数
- [root@www src]# /home/web/apache/bin/apachectl -V
- Server version: Apache/2.2.17 (Unix)
- Server built: Apr 1 2011 06:11:57
- Server's Module Magic Number: 20051115:25
- Server loaded: APR 1.4.2, APR-Util 1.3.10
- Compiled using: APR 1.4.2, APR-Util 1.3.10
- Architecture: 32-bit
- Server MPM: Prefork
- threaded: no
- forked: yes (variable process count)
- Server compiled with....
- -D APACHE_MPM_DIR="server/mpm/prefork"
- -D APR_HAS_SENDFILE
- -D APR_HAS_MMAP
- -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
- -D APR_USE_SYSVSEM_SERIALIZE
- -D APR_USE_PTHREAD_SERIALIZE
- -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT
- -D APR_HAS_OTHER_CHILD
- -D AP_HAVE_RELIABLE_PIPED_LOGS
- -D DYNAMIC_MODULE_LIMIT=128
- -D HTTPD_ROOT="/home/web/apache"
- -D SUEXEC_BIN="/home/web/apache/bin/suexec"
- -D DEFAULT_PIDLOG="logs/httpd.pid"
- -D DEFAULT_SCOREBOARD="logs/apache_runtime_status"
- -D DEFAULT_LOCKFILE="logs/accept.lock"
- -D DEFAULT_ERRORLOG="logs/error_log"
- -D AP_TYPES_CONFIG_FILE="conf/mime.types"
- -D SERVER_CONFIG_FILE="conf/httpd.conf"
3:根据apache编译情况,修改makefile文件如下;在这里不要修改INCLUDES和LIBS参数,否则编译会报错,后面使用软连接实现!
- [root@www src]# grep -v '^#' Makefile |grep -v '^$'
- APACHE_BASE_PATH=/home/web/apache
- builddir=.
- top_srcdir=$(APACHE_BASE_PATH)
- top_builddir=$(APACHE_BASE_PATH)
- include $(APACHE_BASE_PATH)/build/special.mk
- APXS=$(APACHE_BASE_PATH)/bin/apxs
- APACHECTL=$(APACHE_BASE_PATH)/bin/apachectl
- CFLAGS=-Wall
- DEFS=-D_FILE_OFFSET_BITS=64 -DFDFS_OUTPUT_CHUNK_SIZE='256*1024' -DFDFS_MOD_CONF_FILENAME='"/etc/fdfs/mod_fastdfs.conf"'
- INCLUDES=-I/usr/local/include/fastdfs -I/usr/local/include/fastcommon/
- LIBS=-L/usr/local/lib -lfastcommon -lfdfsclient
- SH_LIBS=-lfastcommon -lfdfsclient
- all: local-shared-build
- install: install-modules-yes
- if [ ! -f /etc/fdfs/mod_fastdfs.conf ]; then cp mod_fastdfs.conf /etc/fdfs/; fi
- clean:
- -rm -f mod_fastdfs.o mod_fastdfs.lo mod_fastdfs.slo mod_fastdfs.la
- test: reload
- lynx -mime_header http://localhost/fastdfs
- reload: install restart
- start:
- $(APACHECTL) start
- restart:
- $(APACHECTL) restart
- stop:
- $(APACHECTL) stop
4:对fastfds目录下的lib和include目录做软连接,这里出于个人习惯,喜欢把软件编译在/usr/local目录下,同时按软件名来做子目录
- [root@www src]# ln -s /usr/local/FastFDS/lib/libf* /usr/local/lib
- [root@www src]# ln -s /usr/local/FastFDS/include/fastdfs /usr/local/include/
- [root@www src]# ln -s /usr/local/FastFDS/include/fastcommon/ /usr/local/include/
5:编译安装
- [root@www src]# make
- /home/web/apache/build/libtool --silent --mode=link gcc -g -O2 -pthread -Wall -lfastcommon -lfdfsclient -o
- mod_fastdfs.la -rpath /home/web/apache/modules -module -avoid-version mod_fastdfs.lo
- [root@www src]# make install
- /home/web/apache/build/libtool --silent --mode=install cp mod_fastdfs.la /home/web/apache/modules/
- make[1]: Entering directory `/root/fastdfs-apache-module/src'
- /home/web/apache/build/libtool --silent --mode=install cp mod_fastdfs.la /home/web/apache/modules/
- make[1]: Leaving directory `/root/fastdfs-apache-module/src'
- if [ ! -f /etc/fdfs/mod_fastdfs.conf ]; then cp mod_fastdfs.conf /etc/fdfs/; fi
- [root@www src]# ls /home/web/apache/modules/*fast*
- /home/web/apache/modules/mod_fastcgi.so
- /home/web/apache/modules/mod_fastdfs.so
6:修改apache配置文件,让虚拟主机下的/M00所有请求都交给fastdfs模块处理
- [root@www src]# tail /home/web/apache/conf/httpd-vhosts.conf
- #test fastdfs
- LoadModule fastdfs_module modules/mod_fastdfs.so
- <VirtualHost *:80>
- Servername img.yang.com
- <Location /M00>
- sethandler fastdfs
- </Location>
- </VirtualHost>
7:修改mod_fastdfs.conf文件,指定tracker服务器的ip和端口
- [root@www src]# grep -v '^#' /etc/fdfs/mod_fastdfs.conf |grep -v '^$'
- connect_timeout=2
- network_timeout=30
- base_path=/home/data/fastdfs
- tracker_server=192.168.123.110:22122
- storage_server_port=23000
- group_name=group1
- url_have_group_name = false
- store_path_count=1
- store_path0=/home/data/fastdfs
- log_level=debug
- log_filename=
- response_mode=redirect
- if_alias_prefix=
- http.need_find_content_type=false
8:测试
- [root@www src]# /home/web/apache/bin/apachectl -t
- [2012-07-31 16:19:00] INFO - fastdfs apache / nginx module v1.08, response_mode=redirect, base_path=/home/data/fastdfs,
- path_count=1, connect_timeout=2, network_timeout=30, tracker_server_count=1, storage_server_port=23000, group_name=group1,
- if_alias_prefix=, local_host_ip_count=2, need_find_content_type=0, default_content_type=, anti_steal_token=0, token_ttl=0s,
- anti_steal_secret_key length=0, token_check_fail content_type=, token_check_fail buff length=0,
- storage_sync_file_max_delay=86400s
- Syntax OK
- [root@www src]# /home/web/apache/bin/apachectl -k restart

备注:
当apache服务器不为storage节点时,apache接受到的用户请求将会跳转!
[root@www fdfs]# tail -f /home/web/apache/logs/access_log
192.168.123.102 - - [01/Aug/2012:11:46:08 +0800] "GET /M00/00/00/wKh7FFAYiID1TnRyAAAA4VuHcSQ5892200 HTTP/1.1" 302 -
这个时候,若组内其他可用的storage服务器没有配置fastdfs同apache或者nginx的模块整合,则用户无法访问相应的资源,因而建议所有的storage服务器都进行整合,关于fastdfs同nginx的整合,可参考官方文档或自行google!
