三、配置fastdfs
1、配置fastdfs启动脚本
fastdfs安装完成后，会在/etc/init.d/下生成fdfs的启动脚本，但是脚本中fastdfs的安装路径不对（脚本中默认是/usr/local/bin，但实际安装路径是/usr/bin），所以需要对脚本进行如下处理：
|
1
2
|
sed
-i
's#/usr/local/bin/#/usr/bin/#g'
/etc/init
.d
/fdfs_storaged
sed
-i
's#/usr/local/bin/#/usr/bin/#g'
/etc/init
.d
/fdfs_trackerd
|
2、编辑fastdfs的tracker配置文件

6、注意事项
1）group2同组的Storage2和Storage3 FastDFS服务端口必须一致: port=23000。
2）一台服务器可以装多个组(group)但不能装同组的多个Storage,日志会报错误，日志报错原因是"注意1"
3）Version 4.05之前fastdfs内部绑定了libevent作为http服务器.Version 4.05之后的版本删除了内置的web http服务，内置的web http服务是个累赘，不用也罢！
4）启动storage server时，一直处于僵死状态.启动storage server，storage将连接tracker server，如果连不上，将一直重试。直到连接成功，启动才算真正完成!如果集群中有2台tracker server，而其中一台tracker没有启动，可能会导致storage server一直处于僵死状态

五、fdfs常用命令
1、文件上传命令fdfs_upload_file
用法：
[[email protected] fdfs]# fdfs_upload_file --help
Usage: fdfs_upload_file <config_file> <local_filename> [storage_ip:port] [store_path_index]
下面上传一个文件测试：
[[email protected] fdfs]# echo 'Hello,world.' >>/root/a.txt
[[email protected] fdfs]# fdfs_upload_file /etc/fdfs/client.conf /root/a.txt
group1/M00/00/00/wKhktVf0lLOAMikbAAAADUwC04E360.txt
上传成功后，返回一串带有组和路径标识的字符串，这是文件的id，我们通过这个id在服务器上查找文件：
[[email protected] store]# cd /data/fdfs_storage/store/data/
[[email protected] data]# ls

Hello,world.
# 对文件进行校验，以便于后面进行比对
[ro[email protected] 00]# md5sum wKhktVf0lLOAMikbAAAADUwC04E360.txt
55517e093aa73dee11e6c57a5e980ace wKhktVf0lLOAMikbAAAADUwC04E360.txt
2、下载文件fdfs_download_file
用法：
[[email protected] fdfs]# fdfs_download_file --help
Usage: fdfs_download_file <config_file> <file_id> [local_filename] [<download_offset> <download_bytes>]
这里下载一下刚刚上传的文件：
[[email protected] fdfs]# fdfs_download_file /etc/fdfs/client.conf group1/M00/00/00/wKhktVf0lLOAMikbAAAADUwC04E360.txt /tmp/a.txt
对下载后的文件进行校验：
[[email protected] fdfs]# md5sum /tmp/a.txt
55517e093aa73dee11e6c57a5e980ace /tmp/a.txt
在mylinux4上对服务器上的文件也进行校验，可以看到所有的校验码都是一样的。
[[email protected] ~]# md5sum /data/fdfs_storage/store/data/00/00/wKhktVf0lLOAMikbAAAADUwC04E360.txt
55517e093aa73dee11e6c57a5e980ace /data/fdfs_storage/store/data/00/00/wKhktVf0lLOAMikbAAAADUwC04E360.txt
3、查看文件信息fdfs_file_info
用法：
[[email protected] fdfs]# fdfs_file_info --help
^[[6~Usage: fdfs_file_info <config_file> <file_id>
使用示例：
[[email protected] fdfs]# fdfs_file_info /etc/fdfs/client.conf group1/M00/00/00/wKhktVf0lLOAMikbAAAADUwC04E360.txt
source storage id: 0

file create timestamp: 2016-10-05 13:50:43
file size: 13
file crc32: 1275253633 (0x4C02D381)
4、删除文件fdfs_delete_file
用法：
[[email protected] fdfs]# fdfs_delete_file --help
Usage: fdfs_delete_file <config_file> <file_id>
使用示例：
[[email protected] fdfs]# fdfs_delete_file /etc/fdfs/client.conf group1/M00/00/00/wKhktVf0lLOAMikbAAAADUwC04E360.txt
删除之后没有信息提示，我们再进行下载和查找，结果如下：
[[email protected] fdfs]# fdfs_download_file /etc/fdfs/client.conf group1/M00/00/00/wKhktVf0lLOAMikbAAAADUwC04E360.txt
[2016-10-05 14:08:17] ERROR - file: tracker_proto.c, line: 48, server: 192.168.100.182:23000, response status 2 != 0

5、追加文件内容fdfs_upload_appender和fdfs_upload_appender
用法：
[[email protected] fdfs]# fdfs_upload_appender --help
Usage: fdfs_upload_appender <config_file> <local_filename>
使用示例：
[[email protected] fdfs]# echo "Hello" >/tmp/test1.txt
[[email protected] fdfs]# fdfs_upload_appender /etc/fdfs/client.conf /tmp/test1.txt group1/M00/00/00/wKhktlf0mimEdYdtAAAAAI-wJ-k984.txt

[[email protected] fdfs]# fdfs_append_file /etc/fdfs/client.conf group1/M00/00/00/wKhktlf0mimEdYdtAAAAAI-wJ-k984.txt /tmp/test2.txt
下载文件并查看文件内容：
[[email protected] fdfs]# fdfs_download_file /etc/fdfs/client.conf group1/M00/00/00/wKhktlf0mimEdYdtAAAAAI-wJ-k984.txt /tmp/test3.txt
[[email protected] fdfs]# cat /tmp/test3.txt
Hello
World
6、监控服务器状态fdfs_monitor
用法：
[[email protected] fdfs]# fdfs_monitor
Usage: fdfs_monitor <config_file> [-h <tracker_server>] [list|delete|set_trunk_server <group_name> [storage_id]]
使用示例：

7、移除故障节点示例
假如节点2（mylinux4）上的fastdfs出了问题，我们需要将它从组中移除，可根据下面的命令操作：
1）停掉fastdfs上的storage服务
[[email protected] ~]# /etc/init.d/fdfs_storaged stop
stopping fdfs_storaged ...
.
[[email protected] ~]# lsof -i :23000
2）将问题节点（mylinux4）从组中移除
[[email protected] fdfs]# fdfs_monitor /etc/fdfs/client.conf delete group1 192.168.100.182
[2016-10-05 14:23:59] DEBUG - base_path=/tmp, connect_timeout=30, network_timeout=60, tracker_server_count=2, anti_steal_token=0, anti_steal_secret_key length=0, use_connection_pool=0, g_connection_pool_max_idle_time=3600s, use_storage_id=0, storage server id count: 0
server_count=2, server_index=0
tracker server is 192.168.100.181:22122
delete storage server group1::192.168.100.182 success

移除之后，mylinux4的状态为DELETED。
当mylinux4上的fastdfs修复后，可以再把它加入到fastdfs组中，加入的操作只需要把mylinux4上的fastdfs服务正常启动就好，因为配置文件已经做了配置，如果服务正常的话，修复后的节点可以自动加入到fastdfs组中。
启动fastdfs_storaged服务
[[email protected] ~]# /etc/init.d/fdfs_storaged start
Starting FastDFS storage server:
检查监听端口状态：
[[email protected] ~]# lsof -i :23000
