我們在原來服務器上使用fastdfsV3.02，現在要遷移到新服務器，網上沒有相關的文檔，折騰了很久，現將遷移過程記錄如下，方便其它同學配置和遷移
storage服務器：192.168.1.246
在訪問量都不是很大情況下，將tracker和storage都部署在同一臺服務器上
1.下載相關軟件
wget http://cloud.github.com/downloads/libevent/libevent/libevent-2.0.14-stable.tar.gz
wget http://fastdfs.googlecode.com/files/FastDFS_v3.02.tar.gz
2、編譯安裝libevent庫
tar -zxvf libevent-2.0.14-stable.tar.gz
cd libevent-2.0.14-stable
./configure --prefix=/usr/local/libevent
make && make install
3、配置，編譯安裝FastDFS
tar -zxvf FastDFS_v3.02.tar.gz
cd FastDFS
vi make.sh (修改下面幾處)
TARGET_PREFIX=/usr/local/fastdfs
TARGET_CONF_PATH=/etc/fdfs
WITH_HTTPD=1
WITH_LINUX_SERVICE=1
./make.sh C_INCLUDE_PATH=/usr/local/libevent/include LIBRARY_PATH=/usr/local/libevent/lib
./make.sh install
ls /etc/fdfs/ （安裝成功後會在/etc/fdfs/生成以下文件）
client.conf http.conf mime.types storage.conf tracker.conf
4、修改tracker配置文件
vi /etc/fdfs/tracker.conf
重點關注以下幾個配置項，其它一般默認即可
bind_addr= //綁定的IP
port=22122 //監聽的端口
base_path=/home/data/fastdfs //存放路徑
store_group=group2
reserved_storage_space = 4GB //預留存儲空間
http.server_port=8080
#include httpd.conf //原來是有兩個#號，去掉一個#號即可
5、修改http.conf
vi /etc/fdfs/http.conf
重點關注以下幾個配置項，其它一般默認即可
http.default_content_type = application/octet-stream
http.mime_types_filename=/etc/fdfs/mime.types
http.anti_steal.check_token=false
http.anti_steal.token_ttl=900
http.anti_steal.secret_key=FastDFS1234567890
http.anti_steal.token_check_fail=/usrdata/fastdfs/conf/anti-steal.jpg
6、啓動tracker服務
需要注意tracker.conf文件最後一行爲#include httpd.conf
（1）添加庫文件(以下命令如果不能正確執行，請手動輸入)
echo ’/usr/local/libevent/include/’ >> /etc/ld.so.conf
echo ’/usr/local/libevent/lib/’ >> /etc/ld.so.conf
ldconfig
（2）創建basedir
mkdir -p /usrdata/fastdfs
（3）啓動tracker服務
/usr/local/fastdfs/bin/fdfs_trackerd /etc/fdfs/tracker.conf
echo $?
啓動完成，查看進程：
ps -ef |grep track
在防火牆中增加設置，打開相應的端口：
vi /etc/sysconfig/iptables
-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 22122 -j ACCEPT
-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 8080 -j ACCEPT
二、配置storage服務器：192.168.1.246
如果是在另外一臺服務器上安裝，需要再次安裝FastDFS，在同一臺服務器上則不用，安裝步驟和上面一樣，只配置文件不一樣。
1、增加storage的存儲目錄：
mkdir -p /usrdata/storage
2、修改存儲結點配置文件
vi /etc/fdfs/storage.conf
重點關注以下幾個配置項，其它一般默認即可
group_name=group1
bind_addr=
base_path=/usrdata/storage
store_path_count=1
store_path0=/usrdata/storage
tracker_server=192.168.1.246:22122
http.server_port=8888
#include httpd.conf //原來是有兩個#號，去掉一個#號即可
3、修改測試客戶端配置文件（用於測試）
vi /etc/fdfs/client.conf
重點關注以下幾個配置項，其它一般默認即可
base_path=/usrdata/fastdfs
tracker_server=192.168.1.246:22122
http.tracker_server_port=8080
#include httpd.conf
4、修改http.conf
vi /etc/fdfs/http.conf
重點關注以下幾個配置項，其它一般默認即可
http.default_content_type = application/octet-stream
http.mime_types_filename=/etc/fdfs/mime.types
http.anti_steal.check_token=false
http.anti_steal.token_ttl=900
http.anti_steal.secret_key=FastDFS1234567890
http.anti_steal.token_check_fail=/usrdata/fastdfs/conf/anti-steal.jpg
5、啓動storage
/usr/local/FastDFS/bin/fdfs_storaged /etc/fdfs/storage.conf
三、測試文件上傳
上傳文件/home/test/a.jpg用於測試
/usr/local/FastFDS/bin/fdfs_test /etc/fdfs/client.conf upload /home/test/a.jpg
This is FastDFS client test program v3.02

四、常見命令：
1、啓動：
/usr/local/fastdfs/bin/fdfs_trackerd /etc/fdfs/tracker.conf
/usr/local/fastdfs/bin/fdfs_storaged /etc/fdfs/storage.conf
2、停止：
/usr/local/fastdfs/bin/stop.sh /usr/local/fastdfs/bin/fdfs_trackerd
/usr/local/fastdfs/bin/stop.sh /usr/local/fastdfs/bin/fdfs_storaged
3、重啓：
/usr/local/fastdfs/bin/restart.sh /usr/local/fastdfs/bin/fdfs_trackerd
/usr/local/fastdfs/bin/restart.sh /usr/local/fastdfs/bin/fdfs_storaged
五、遷移：
以上是正常的配置及啓動，我是要將文件從舊的fastdfs服務器遷移到新的fastdfs文件服務器上來：
1、先將所有storage進程都停止：
/usr/local/fastdfs/bin/stop.sh /usr/local/fastdfs/bin/fdfs_storaged
2、修改storage.conf文件
vi /etc/fdfs/storage.conf
將tracker_server的IP設置成舊服務器IP192.168.1.53
tracker_server=192.168.1.53:22122
3、啓動storage進程：
/usr/local/fastdfs/bin/fdfs_storaged /etc/fdfs/storage.conf
此時storage服務器開始同步；
查看同步進程：
在舊tracker服務器執行：
/usr/local/fastdfs/bin/fdfs_monitor /etc/fdfs/storage.conf
可以看到同步進度；
4、同步完成後，在新的fastdfs文件服務器192.168.1.246上停止storage進程：
/usr/local/fastdfs/bin/stop.sh /usr/local/fastdfs/bin/fdfs_storaged
5、修改storage.conf文件，將tracker修改成新的tracker IP
vi /etc/fdfs/storage.conf
tracker_server=192.168.1.246:22122
6、修改.data_init_flag文件：
cd /usrdata/storage/data/
vi .data_init_flag
將sync_src_server配置項留空，其它配置項不變
sync_src_server=
7、啓動storage進程
/usr/local/fastdfs/bin/fdfs_storaged /etc/fdfs/storage.conf
查看storage進程狀態：
/usr/local/fastdfs/bin/fdfs_monitor /etc/fdfs/storage.conf
完成。
