CentOS 6.5上安装并配置FastDFS
一、下载并安装libfastcommon1

cd /opt/tools
git clone https://github.com/happyfish100/libfastcommon.git
cd libfastcommon/
./make.sh
./make.sh install
二、下载并安装fastdfs

cd ../
wget https://github.com/happyfish100/fastdfs/archive/V5.05.tar.gz
tar -zxf V5.05.tar.gz
cd fastdfs-5.05/
./make.sh
./make.sh install
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

root 2653 18040 01:43 pts/0 00:00:00 grep fdfs_storage
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
四、配置fastdfs客户端

> tracker_server=192.168.100.181:22122
> tracker_server=192.168.100.182:22122
五、fdfs常用命令
1、文件上传命令fdfs_upload_file
用法：
# fdfs_upload_file --help
Usage: fdfs_upload_file <config_file> <local_filename>
下面上传一个文件测试：
# echo 'Hello,world.' >>/root/a.txt
# 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：
# cd /data/fdfs_storage/store/data/
# ls

2、下载文件fdfs_download_file
用法：
# fdfs_download_file --help
Usage: fdfs_download_file <config_file> <file_id> [<download_offset> <download_bytes>]
这里下载一下刚刚上传的文件：
# 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：
# 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。
# 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：
# fdfs_file_info --help
^[[6~Usage: fdfs_file_info <config_file> <file_id>
使用示例：
# fdfs_file_info /etc/fdfs/client.conf group1/M00/00/00/wKhktVf0lLOAMikbAAAADUwC04E360.txt
source storage id: 0
source ip address: 192.168.100.181
file create timestamp: 2016-10-05 13:50:43
file size: 13

4、删除文件fdfs_delete_file
用法：
# fdfs_delete_file --help
Usage: fdfs_delete_file <config_file> <file_id>
使用示例：
# 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：
# fdfs_download_file /etc/fdfs/client.conf group1/M00/00/00/wKhktVf0lLOAMikbAAAADUwC04E360.txt
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：
# fdfs_upload_appender --help
Usage: fdfs_upload_appender <config_file> <local_filename>
使用示例：
# echo "Hello" >/tmp/test1.txt
# fdfs_upload_appender /etc/fdfs/client.conf /tmp/test1.txt group1/M00/00/00/wKhktlf0mimEdYdtAAAAAI-wJ-k984.txt

使用示例：
# 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：
# fdfs_download_file /etc/fdfs/client.conf group1/M00/00/00/wKhktlf0mimEdYdtAAAAAI-wJ-k984.txt /tmp/test3.txt
# cat /tmp/test3.txt

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
# /etc/init.d/fdfs_storaged stop
stopping fdfs_storaged ...
.
# lsof -i :23000
2）将问题节点（mylinux4）从组中移除
# fdfs_monitor /etc/fdfs/client.conf delete group1 192.168.100.182
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
3）移除成功，使用fdfs_monitor命令进行监控
# fdfs_monitor /etc/fdfs/client.conf
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

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
# /etc/init.d/fdfs_storaged start
Starting FastDFS storage server:
检查监听端口状态：
# lsof -i :23000
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
fdfs_stor 1222 root 5uIPv410873 0t0TCP *:inovaport1 (LISTEN)

再次使用监控命令查看服务器状态：
