Centos7下FastDFS集群搭建

1 安装包准备

• fastdfs6.06 源码地址：fastdfs源码地址

• libfastcommon 源码地址：libfastcommon依赖库源码地址

• fastdfs-nginx-module 源码地址: fastdfs-nginx-module源码地址

• nginx1.16 离线包以及依赖包，参考：nginx1.16离线安装文档

1. libfastcommon 需要在tracker，storage 节点分别安装。
2. 在storage节点需要安装nginx，fastdfs-nginx-module（fastdfs之前内置了http server，现在如果需要直接通过http下载需要安装nginx，fastdfs-nginx-module）
3. fastdfs-nginx-module group组中数据同步延迟问题，可以将请求重定向他其他节点。

2 环境准备

简易集群部署，我这里是最小环境安装，使用了2台机器 10.0.3.27，10.0.3.28 Centos7系统。

实际环境中：可以单独部署tracker集群. 程序Client上传文件的时候sdk连接tracker集群，下载的时候，可以加几台机器部署一层Nginx+Keepalived ，将请求转发到 storage节点上的Nginx。
我这里将tracker，storage部署到了一起。
10.0.3.27 部署 tracker，storage(nginx，fastdfs-nginx-module)
10.0.3.28 部署 tracker，storage(nginx，fastdfs-nginx-module)

3 安装

3.1 安装libfastcommon

此lib库为基础lib在tracker，storage都依赖了。需要在10.0.3.27，10.0.3.28分别安装。解压下载下来的libfastcommon包.在解压目录执行./make.sh,执行完毕后执行./make.sh install.

[root@sybj-int-26 libfastcommon-1.0.43]# ./make.sh install
mkdir -p /usr/lib64
mkdir -p /usr/lib
mkdir -p /usr/include/fastcommon
install -m 755 libfastcommon.so /usr/lib64
install -m 644 common_define.h hash.h chain.h logger.h base64.h shared_func.h pthread_func.h ini_file_reader.h _os_define.h sockopt.h sched_thread.h http_func.h md5.h local_ip_func.h avl_tree.h ioevent.h ioevent_loop.h fast_task_queue.h fast_timer.h process_ctrl.h fast_mblock.h connection_pool.h fast_mpool.h fast_allocator.h fast_buffer.h skiplist.h multi_skiplist.h flat_skiplist.h skiplist_common.h system_info.h fast_blocked_queue.h php7_ext_wrapper.h id_generator.h char_converter.h char_convert_loader.h common_blocked_queue.h multi_socket_client.h skiplist_set.h fc_list.h json_parser.h buffered_file_writer.h /usr/include/fastcommon
if [ ! -e /usr/lib/libfastcommon.so ]; then ln -s /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so; fi

3.2 安装fastdfs

3.2.1 编译fastdfs安装

将下载下来的fastdfs解压，进入到解压目录执行./make.sh 然后执行./make.sh install

[root@sybj-int-26 fastdfs-6.06]# ./make.sh install
mkdir -p /usr/bin
mkdir -p /etc/fdfs
cp -f fdfs_trackerd /usr/bin
if [ ! -f /etc/fdfs/tracker.conf.sample ]; then cp -f ../conf/tracker.conf /etc/fdfs/tracker.conf.sample; fi
if [ ! -f /etc/fdfs/storage_ids.conf.sample ]; then cp -f ../conf/storage_ids.conf /etc/fdfs/storage_ids.conf.sample; fi
mkdir -p /usr/bin
mkdir -p /etc/fdfs
cp -f fdfs_storaged  /usr/bin
if [ ! -f /etc/fdfs/storage.conf.sample ]; then cp -f ../conf/storage.conf /etc/fdfs/storage.conf.sample; fi
mkdir -p /usr/bin
mkdir -p /etc/fdfs
mkdir -p /usr/lib64
mkdir -p /usr/lib

fastdfs的可执行文件安装到了：/usr/bin/ 目录 配置文件在 /etc/fdfs/目录

3.2.1 配置Tracker

# 进入配置文件目录
cd /etc/fdfs
# 拷贝出一个tracker.conf
cp tracker.conf.sample tracker.conf
# 修改配置
vim tracker.conf

# is this config file disabled
# false for enabled 启用配置
# true for disabled
disabled = false

# bind an address of this host
# empty for bind all addresses of this host 将绑定到0.0.0.0
bind_addr =

# the tracker server port 默认端口
port = 22122

# connect timeout in seconds
# default value is 30
# Note: in the intranet network (LAN), 2 seconds is enough.
connect_timeout = 5

# network timeout in seconds for send and recv
# default value is 30
network_timeout = 60

# 改变一下 tracker server 的工作目录和日志目录
# 此目录需要提前创建好
# the base path to store data and log files
base_path = /opt/ylbzj/fastdfs_tracker_data
# 最大连接数
# max concurrent connections this server support
# you should set this parameter larger, eg. 10240
# default value is 256
max_connections = 1024

# 处理连接的accept线程数，可根据CPU核数而定
# accept thread count
# default value is 1 which is recommended
# since V4.07
accept_threads = 4

# 工作线程数量 ，根据CPU数量而定
# work thread count
# work threads to deal network io
# default value is 4
# since V2.00
work_threads = 64

# tracker 选择storage group 时的策略
# the method for selecting group to upload files
# 0: round robin
# 1: specify group
# 2: load balance, select the max free space group to upload file
store_lookup = 2

# 如果指定store_lookup = 1 的时候，指定特殊组
# which group to upload file
# when store_lookup set to 1, must set store_group to the group name
store_group = group2

# 我理解的是同一个组内storage server的选择策略
# which storage server to upload file
# 0: round robin (default)
# 1: the first server order by ip address
# 2: the first server order by priority (the minimal)
# Note: if use_trunk_file set to true, must set store_server to 1 or 2
store_server = 0

# 多磁盘配置，选择策略
# which path (means disk or mount point) of the storage server to upload file
# 0: round robin
# 2: load balance, select the max free space path to upload file
store_path = 0

# which storage server to download file
# 0: round robin (default)
# 1: the source storage server which the current file uploaded to
download_server = 0

# storage server 能使用磁盘的 总磁盘 * (100-X) / 100 = 可使用磁盘
# reserved storage space for system or other applications.
# if the free(available) space of any stoarge server in 
# a group <= reserved_storage_space, no file can be uploaded to this group.
# bytes unit can be one of follows:
### G or g for gigabyte(GB)
### M or m for megabyte(MB)
### K or k for kilobyte(KB)
### no unit for byte(B)
### XX.XX% as ratio such as: reserved_storage_space = 10%
reserved_storage_space = 20%

没有列举全部配置，其他的配置都是默认配置。

咱们目前在2台机器上安装tracker server，以上步骤在另一台10.0.3.28上同样执行一样，将本次修改好的配置文件同步到10.0.3.28. 确保base_path指定的目录已经创建了

     scp tracker.conf root@10.0.3.28:/etc/fdfs/

分别在两台机器上启动tracker server

/etc/init.d/fdfs_trackerd start

查看是否启动成功

root@sybj-int-27 ~]# ps aux|grep dfs
root      79642  0.0  0.0 107000  5932 ?        Sl   14:23   0:00 /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start
root      79763  0.0  0.0 112652   920 pts/0    S+   14:24   0:00 grep --color=auto dfs
[root@sybj-int-27 ~]# 

两台tracker server 安装完毕！

3.2.2 配置Storage Server

# 进入配置文件目录
cd /etc/fdfs
# 拷贝出一个storage.conf
cp storage.conf.sample storage.conf
# 修改配置
vim storage.conf

# 本地Storage server 的组
# the name of the group this storage server belongs to
# comment or remove this item for fetching from tracker server,
# in this case, use_storage_id must set to true in tracker.conf,
# and storage_ids.conf must be configured correctly.
group_name = group1

# bind an address of this host
# empty for bind all addresses of this host
bind_addr =

# if bind an address of this host when connect to other servers 
# (this storage server as a client)
# true for binding the address configured by the above parameter: "bind_addr"
# false for binding any address of this host
client_bind = true

# the storage server port 默认端口
port = 23000

# Storage server 的工作目录，存储日志，binlog等
# the base path to store data and log files
# NOTE: the binlog files maybe are large, make sure
#       the base path has enough disk space,
#       eg. the disk free space should > 50GB
base_path = /opt/ylbzj/fastdfs_storge

# accept thread count
# default value is 1 which is recommended
# since V4.07
accept_threads = 4

# work thread count
# work threads to deal network io
# default value is 4
# since V2.00
work_threads = 64

# NOTE: 我就使用了一块磁盘，所以保持默认值
# store path (disk or mount point) count, default value is 1
store_path_count = 1

# store_path#, based on 0, to configure the store paths to store files
# if store_path0 not exists, it's value is base_path (NOT recommended)
# the paths must be exist.
#
# IMPORTANT NOTE:
#       the store paths' order is very important, don't mess up!!!
#       the base_path should be independent (different) of the store paths
# Storage Server的数据存储地址，这里配置和base_path不同的目录
store_path0 = /opt/ylbzj/fastdfs_storge_data1
# 如果多块磁盘指定多个路径
#store_path1 = /home/yuqing/fastdfs2

# 配置Tracker Server的地址
tracker_server = 10.0.3.27:22122
tracker_server = 10.0.3.28:22122

以上Storage Server 步骤在另一台10.0.3.28上同样执行一样，将本次修改好的配置文件同步到10.0.3.28. 确保base_path，store_path0 指定的目录已经创建了

将所有的Storage Server 启动,咱们这里是2台机器，分别启动

 /etc/init.d/fdfs_storaged start

3.2.1 测试上传文件到fastdfs

上边的步骤，已经将tracker,StorageServer 安装好了。接下来用fastdfs自带的client上传文件测试一下

cd 到fastdfs的源码目录

/opt/ylbzj/soft/fastdfs-6.06/conf
[root@sybj-int-26 conf]# ll
total 92
-rw-r--r--. 1 root root 23981 Dec 31 07:36 anti-steal.jpg
-rw-r--r--. 1 root root  1909 Dec 31 07:36 client.conf
-rw-r--r--. 1 root root   965 Dec 31 07:36 http.conf
-rw-r--r--. 1 root root 31172 Dec 31 07:36 mime.types
-rw-r--r--. 1 root root 10246 Dec 31 07:36 storage.conf
-rw-r--r--. 1 root root   620 Dec 31 07:36 storage_ids.conf
-rw-r--r--. 1 root root  9138 Dec 31 07:36 tracker.conf
[root@sybj-int-26 conf]# 

将client.conf 拷贝到一台机器（任意一台测试即可）的 /etc/fdfs/目录下

cp client.conf /etc/fdfs
cd /etc/fdfs
vim client.conf

编辑配置一下client.conf

# the base path to store log files
# 根据自己地址指定一个即可
base_path = /home/test

# tracker_server can ocur more than once for multi tracker servers.
# the value format of tracker_server is "HOST:PORT",
#   the HOST can be hostname or ip address,
#   and the HOST can be dual IPs or hostnames seperated by comma,
#   the dual IPS must be an inner (intranet) IP and an outer (extranet) IP,
#   or two different types of inner (intranet) IPs.
#   for example: 192.168.2.100,122.244.141.46:22122
#   another eg.: 192.168.1.10,172.17.4.21:22122
#NOTE: 增加 tracker server地址
tracker_server = 10.0.3.27:22122
tracker_server = 10.0.3.28:22122

上传文件

   [root@sybj-int-27 fdfs]# /usr/bin/fdfs_upload_file /etc/fdfs/client.conf client.conf
group1/M00/00/00/CgADHF57AKaADvJdAAAHYyTJSr064.conf

上传成功后返回了文件的组，磁盘，文件目录，文件名等信息group1/M00/00/00/CgADHF57AKaADvJdAAAHYyTJSr064.conf

3.2.2 安装nginx，fastdfs-nginx-module

• 上边已经能把文件传到fastdfs，还无法通过http 下载
• 现在咱们2台机器都安装了，tracker，storage server。http下载的话需要在storage server 上安装nginx，fastdfs-nginx-module
• 咱们2台机器都是storage server 所以都需要安装nginx

3.2.2.1 从源码包安装nginx

• 参考上文中安装nginx的步骤 nginx1.16离线安装文档
• 别着急直接安装nginx，需要先add-module将fastdfs-nginx-module添加到nginx中。

先解压fastdfs-nginx-module

[root@sybj-int-26 soft]# tar -xvf fastdfs-nginx-module-1.22.zip 

切换到nginx的源码目录执行

 [root@sybj-int-26 nginx]# cd nginx-1.16.1/
[root@sybj-int-26 nginx-1.16.1]# ll

然后执行nginx 安装 make make install

到 fastdfs-nginx-module-1.22 目录 拷贝 mod_文件到/etc/fdfs目录

[root@sybj-int-26 soft]# cd fastdfs-nginx-module-1.22/

编辑mod_fastdfs.conf

cd /etc/fdfs/mod_fastdfs.conf
vim mod_fastdfs.conf

storage_ids_filename = storage_ids.conf

# FastDFS tracker_server can ocur more than once, and tracker_server format is
#  "host:port", host can be hostname or ip address
# valid only when load_fdfs_parameters_from_tracker is true
# NOTE: 配置 tracker server 列表

# 本次 groupName 咱们目前就配置了一个group
# the group name of the local storage server
group_name=group1

# NOTE: 修改为true 支持http 直接下载
# if the url / uri including the group name
# set to false when uri like /M00/00/00/xxx
# set to true when uri like ${group_name}/M00/00/00/xxx, such as group1/M00/xxx

# the paths must be exist
# must same as storage.conf
store_path0=/opt/ylbzj/fastdfs_storge_data1
#store_path1=/home/yuqing/fastdfs1

• 以上是部分配置，主要配置完毕，其他的配置项都是默认的
• 如果有多个组设置，需要修改下边的配置

# set the group count
# set to none zero to support multi-group on this storage server
# set to 0  for single group only
# groups settings section as [group1], [group2], ..., [groupN]
# default value is 0
# since v1.14
group_count = 0

# group settings for group #1
# since v1.14
# when support multi-group on this storage server, uncomment following section
#[group1]
#group_name=group1
#storage_server_port=23000
#store_path_count=2
#store_path0=/home/yuqing/fastdfs
#store_path1=/home/yuqing/fastdfs1

# group settings for group #2

#[group2]
#group_name=group2
#storage_server_port=23000
#store_path_count=1
#store_path0=/home/yuqing/fastdfs

目前咱们就配置了一个组，没有配置以上配置项

fastdfs-nginx-module 依赖了两个配置文件 http.conf, mine.types文件，这两个文件在 fastdfs源码目录的conf目录下，需要拷贝到/etc/fdfs目录

[root@sybj-int-26 src]# cd /opt/ylbzj/soft/fastdfs-6.06/
[root@sybj-int-26 fastdfs-6.06]# cd conf/
[root@sybj-int-26 conf]# ll
total 92
-rw-r--r--. 1 root root 23981 Dec 31 07:36 anti-steal.jpg
-rw-r--r--. 1 root root  1909 Dec 31 07:36 client.conf
-rw-r--r--. 1 root root   965 Dec 31 07:36 http.conf
-rw-r--r--. 1 root root 31172 Dec 31 07:36 mime.types

-rw-r--r--. 1 root root  9138 Dec 31 07:36 tracker.conf
[root@sybj-int-26 conf]# cp http.conf mime.types /etc/fdfs

查看一下http.conf

  vim /etc/fdfs/http.conf

# if use token to anti-steal
# default value is false (0)
http.anti_steal.check_token = false

# token TTL (time to live), seconds
# default value is 600
http.anti_steal.token_ttl = 900

# secret key to generate anti-steal token
# this parameter must be set when http.anti_steal.check_token set to true
# the length of the secret key should not exceed 128 bytes
http.anti_steal.secret_key = FastDFS1234567890

http.conf 中的这几项用于防盗链设置，http.anti_steal.check_token = true 表示开启token验证。http下载的时候需要携带?token=xxxx 参数

修改一下nginx.conf,增加一个location 匹配。 nginx.conf 文件在/usr/local/nginx/conf目录

[root@sybj-int-27 fdfs]# cd /usr/local/nginx/conf/
[root@sybj-int-27 conf]# vim nginx.conf

     server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }
        # 增加这一行
        location ~/group([0-9])/M00 {
            ngx_fastdfs_module;
        }

至此nginx 和fastdfs-nginx-module 配置完毕，所有storage节点都需要安装，执行以上步骤。
在两台机器上 启动nginx

   /usr/local/nginx/sbin/nginx

测试一下：

[root@sybj-int-27 fdfs]# /usr/bin/fdfs_upload_file /etc/fdfs/client.conf client.conf
group1/M00/00/00/CgADG157DIaAWoGUAAAHXJ4aSxg95.conf
[root@sybj-int-27 fdfs]# wget localhost/group1/M00/00/00/CgADG157DIaAWoGUAAAHXJ4aSxg95.conf

3.2.3 扩展

• 目前两台机器上都有storage，nginx，http目前没有一个统一的入口，可以在加1-N台 单独的nginx服务器，配置keepalived， 将独立安装的nginx 的请求路由到 storage server上的nginx端口即可
• 目前部署了单个group群组。可以配置多个group，拷贝storage.conf修改，修改组名，增加机器部署。

在新的storage server上安装好storage server 和nginx。
修改storage.conf

   # 多组部署
   group_name = groupN

修改mod_fastdfs.conf

# the group name of the local storage server
group_name=groupN

3.2.4 防火墙设置

centos7 防火墙使用的是firewall
在每台机器上开发端口：22122 ，23000， 80（nginx端口）

# firewall-cmd --zone=public(作用域) --add-port=80/tcp(端口和访问类型) --permanent(永久生效)
firewall-cmd --zone=public --add-port=XXX/tcp --permanent
firewall-cmd --reload    # 重新载入，更新防火墙规则

4 nginx，tracker，storage 开机启动

使用工具systemctl

4.1 nginx 开机启动

cd /usr/lib/systemd/system
vim nginx.service
