FastDFSV3.02的安装和配置、迁移


背景：

我们在原来服务器上使用fastdfsV3.02，现在要迁移到新服务器，网上没有相关的文档，折腾了很久，现将迁移过程记录如下，方便其它同学配置和迁移

tracker服务器：192.168.1.246
storage服务器：192.168.1.246

在访问量都不是很大情况下，将tracker和storage都部署在同一台服务器上

一、配置tracker服务器：192.168.1.246
1.下载相关软件
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、编译安装libevent库
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，编译安装FastDFS
tar -zxvf FastDFS_v3.02.tar.gz
cd FastDFS
vi make.sh (修改下面几处)
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/ （安装成功后会在/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
重点关注以下几个配置项，其它一般默认即可


bind_addr= //绑定的IP
port=22122 //监听的端口
base_path=/home/data/fastdfs //存放路径
store_group=group2
reserved_storage_space = 4GB //预留存储空间
http.server_port=8080
#include httpd.conf //原来是有两个#号，去掉一个#号即可


5、修改http.conf
vi /etc/fdfs/http.conf
重点关注以下几个配置项，其它一般默认即可

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、启动tracker服务
需要注意tracker.conf文件最后一行为#include httpd.conf
（1）添加库文件(以下命令如果不能正确执行，请手动输入)
echo ’/usr/local/libevent/include/’ >> /etc/ld.so.conf
echo ’/usr/local/libevent/lib/’ >> /etc/ld.so.conf
ldconfig


（2）创建basedir
mkdir -p /usrdata/fastdfs


（3）启动tracker服务
/usr/local/fastdfs/bin/fdfs_trackerd /etc/fdfs/tracker.conf
echo $?
启动完成，查看进程：
ps -ef |grep track

在防火墙中增加设置，打开相应的端口：
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服务器：192.168.1.246
如果是在另外一台服务器上安装，需要再次安装FastDFS，在同一台服务器上则不用，安装步骤和上面一样，只配置文件不一样。
1、增加storage的存储目录：
mkdir -p /usrdata/storage

2、修改存储结点配置文件
vi /etc/fdfs/storage.conf
重点关注以下几个配置项，其它一般默认即可

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 //原来是有两个#号，去掉一个#号即可


3、修改测试客户端配置文件（用于测试）
vi /etc/fdfs/client.conf
重点关注以下几个配置项，其它一般默认即可

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
重点关注以下几个配置项，其它一般默认即可

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、启动storage
/usr/local/FastDFS/bin/fdfs_storaged /etc/fdfs/storage.conf

三、测试文件上传
上传文件/home/test/a.jpg用于测试
/usr/local/FastFDS/bin/fdfs_test /etc/fdfs/client.conf upload /home/test/a.jpg

四、常见命令：

1、启动：
/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、重启：
/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、迁移：
以上是正常的配置及启动，我是要将文件从旧的fastdfs服务器迁移到新的fastdfs文件服务器上来：
1、先将所有storage进程都停止：
/usr/local/fastdfs/bin/stop.sh /usr/local/fastdfs/bin/fdfs_storaged
2、修改storage.conf文件
vi /etc/fdfs/storage.conf
将tracker_server的IP设置成旧服务器IP192.168.1.53
tracker_server=192.168.1.53:22122


3、启动storage进程：
/usr/local/fastdfs/bin/fdfs_storaged /etc/fdfs/storage.conf
此时storage服务器开始同步；


查看同步进程：
在旧tracker服务器执行：
/usr/local/fastdfs/bin/fdfs_monitor /etc/fdfs/storage.conf
可以看到同步进度；


4、同步完成后，在新的fastdfs文件服务器192.168.1.246上停止storage进程：
/usr/local/fastdfs/bin/stop.sh /usr/local/fastdfs/bin/fdfs_storaged

5、修改storage.conf文件，将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
将sync_src_server配置项留空，其它配置项不变
sync_src_server=


7、启动storage进程
/usr/local/fastdfs/bin/fdfs_storaged /etc/fdfs/storage.conf


查看storage进程状态：
/usr/local/fastdfs/bin/fdfs_monitor /etc/fdfs/storage.conf


完成。
