FastdDFS入门一环境搭建

1.1、依赖搭建

安装FastDFS服务需要安装四个软件：

libfastcommon：fastDFS与FastDHT中提取的公用的C函数的库。
fastdfs： fastDFS软件
fastdfs-nginx-module：当前主流web服务器的扩展模块(包括nginx/apache)，其用意在于利用web服务器直接对本机storage数据文件提供http服务，以提高文件下载的性能
nginx服务器

因为fastDFS是C语言编写的，因此需要fastDFS需要C语言的编译环境。首先需要安装编译环境

yum -y install cmake make gcc-c++

FastDFS还依赖一个libevent库，因此还需要安装libevent

yum -y install libevent

1.2、libfastcommon安装

把所有的fastDFS都安装到/usr/local/fastdfs目录下：

mkdir /usr/local/fastdfs

把解压的libfastcommon拷贝到/usr/local/fastdfs目录下

cd /usr/local/fastdfs/libfastcommon-master
./make.sh
./make install

执行完上述命令之后，会打印如下内容：

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 locked_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 uniq_skiplist.h fc_list.h locked_list.h json_parser.h buffered_file_writer.h server_id_func.h fc_queue.h sorted_queue.h fc_memory.h shared_buffer.h thread_pool.h fc_atomic.h array_allocator.h sorted_array.h /usr/include/fastcommon

其作用就是把libfastcommon.so 安装到/usr/lib64目录下，并把一些头文件安装到 /usr/include/fastcommon目录下。

因此FastDFS引用的库的目录是/usr/local/lib，因此需要把之前安装的主库中的一些库目录做软链接，或者拷贝到/usr/local/lib目录下。

ln -s  /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so

1.3、FastDFS安装

把下载的后的安装包解压到/usr/local/fastdfs目录

cd /usr/local/fastdfs/fastdfs-master

在fastDFS目录下的make.sh中有如下的代码：

ENABLE_STATIC_LIB=0
ENABLE_SHARED_LIB=1
TARGET_PREFIX=$DESTDIR/usr
TARGET_CONF_PATH=$DESTDIR/etc/fdfs
# 会在/usr/lib/systemd/system 目录下生成 fdfs_trackerd.service ,这样就可以通过systemctl命令来管理服务
TARGET_SYSTEMD_PATH=$DESTDIR/usr/lib/systemd/system

TARGET_PREFIX属性是用来指定fastDFS的默认安装路径，在集群情况下不要修改，在单节点情况下可以修改。

改成

TARGET_PREFIX=$DESTDIR/usr/local

在源码目录下执行:

./make.sh
./make.sh install

FastDFS的安装位置：

/usr/local/bin是可执行文件所在的位置，默认在/usr/bin中
/etf/fdfs 配置文件所在位置，默认也是这个位置
/usr/local/lib64主程序代码所在位置，默认在/usr/bin中
/usr/local/include/fastdfs包含的一些插件组所在的位置，默认在/usr/include/fastdfs中。

在之前解压源码的目录/usr/local/fastdfs/目录中的主程序中的init.d目录下有如下两个文件：

-rwxr-xr-x. 1 root root 961 9月  14 10:40 fdfs_storaged
-rwxr-xr-x. 1 root root 963 9月  14 10:40 fdfs_trackerd

上述两个脚本是启动服务脚本。如果在安装过程中没有把这两个脚本安装到/etc/init.d/目录下，则把源码中的这两个脚本拷贝到/etc/init.d/目录下。

在/etc/fdfs/目录下的配置文件如下：

-rw-r--r--. 1 root root  1909 11月 23 23:55 client.conf
-rw-r--r--. 1 root root 10246 11月 23 23:55 storage.conf
-rw-r--r--. 1 root root   620 11月 23 23:55 storage_ids.conf
-rw-r--r--. 1 root root  9138 11月 23 23:55 tracker.conf

如果当前安装节点作为storage节点，就修改storage.conf配置文件。

如果当前节点作为tracker节点，就修改tracker.conf配置文件。但是注意备份。

在/usr/local/bin目录下的命令就是fastdfs的命令

-rwxr-xr-x. 1 root root  369360 11月 23 23:55 fdfs_appender_test
-rwxr-xr-x. 1 root root  369144 11月 23 23:55 fdfs_appender_test1

-rwxr-xr-x. 1 root root  356752 11月 23 23:55 fdfs_file_info
-rwxr-xr-x. 1 root root  376472 11月 23 23:55 fdfs_monitor

-rwxr-xr-x. 1 root root  378456 11月 23 23:55 fdfs_test1
-rwxr-xr-x. 1 root root  522640 11月 23 23:55 fdfs_trackerd
-rwxr-xr-x. 1 root root  357016 11月 23 23:55 fdfs_upload_appender
-rwxr-xr-x. 1 root root  358032 11月 23 23:55 fdfs_upload_file

1.4、Tracker配置

FastDFS的配置文件默认在/etc/fdfs/目录下：

-rw-r--r--. 1 root root  1909 11月 23 23:55 client.conf
-rw-r--r--. 1 root root 10246 11月 23 23:55 storage.conf
-rw-r--r--. 1 root root   620 11月 23 23:55 storage_ids.conf
-rw-r--r--. 1 root root  9144 11月 24 22:04 tracker.conf

client.conf配置客户端

storage.conf配置存储节点

tracker.conf配置追踪节点

tracker.conf

安装完成FastDFS之后，如果配置tracker.conf配置文件，则此节点为tracker，如果配置了storage.conf，则此节点为storage.

在tracker.conf的配置文件中的配置如下；

base_path用来存储数据与日志，Tracker服务启动成功后，会在base_path下创建data、logs两个目录。目录结构如下：

${base_path}
  |__data
  |   |__storage_groups.dat：存储分组信息
  |   |__storage_servers.dat：存储服务器列表
  |__logs
  |   |__trackerd.log： tracker server 日志文件

修改tracker启动脚本

在/etc/init.d/目录下的fdfs_trackerd脚本是tracker的启动脚本，修改这个启动脚本。

fastDFS默契情况下会把可执行文件放在/usr/bin目录下，但是我们在安装时修改了默认配置。

把make.sh中的

TARGET_PREFIX=$DESTDIR/usr

改成了

TARGET_PREFIX=$DESTDIR/usr/local

因此启动脚本也需要修改，让启动脚本可以找到可执行文件把

PRG=/usr/bin/fdfs_trackerd
CONF=/etc/fdfs/tracker.conf

改成

PRG=/usr/local/bin/fdfs_trackerd
CONF=/etc/fdfs/tracker.conf

启动tracker

./fdfs_trackerd start
./fdfs_trackerd status
fdfs_trackerd (pid 1854) 正在运行...

./fdfs_trackerd stop

也可以采取

ps -ef | grep fdfs 命令查看是否启动成功。

如果想要设置开机启动，可以在/etc/rc.d/rc.local目录下添加如下代码：

/etc/init.d/fdfs_trackerd start

1.5、Storage配置

storage.conf

在/etc/fdfs/目录下storage.conf就是Storage节点的配置文件。打开这个配置文件：

在此配置文件中，我们需要配置如下的内容：

base_path = /fdfs/storage/base 配置信息与日志目录

store_path0 = /fdfs/storage/store 存储文件的目录

tracker_server = 192.168.209.121:22122 追踪服务器的地址

创建配置的目录

[root@localhost fdfs]# mkdir -p /fdfs/storage/base
[root@localhost fdfs]# mkdir -p /fdfs/storage/store

修改storage的启动脚本

同理，因此我们修改了fastDFS的默认位置，因此还是需要修改启动脚本的。

把


PRG=/usr/bin/fdfs_storaged

修改成


PRG=/usr/local/bin/fdfs_storaged

启动storage

[root@localhost init.d]# ./fdfs_storaged start
Starting FastDFS storage server: 
[root@localhost init.d]# ./fdfs_storaged status
fdfs_storaged (pid 1979) 正在运行...
[root@localhost init.d]# ps -ef |grep  fdfs
root       1854      1  0 23:01 ?        00:00:00 /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
root       1979      1  8 23:40 ?        00:00:03 /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf
root       2000   1650  0 23:41 pts/0    00:00:00 grep --color=auto fdfs

1.6、客户端配置

客户端配置是为了用命令行测试我们的fastDFS，如果我们不准备用命令行测试我们的fastDFS，我们可以不用配置这些。

客户端配置既可以放在tracker服务器上，也可以放在storage服务器上。

client.conf

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

# network timeout in seconds
# default value is 30s
network_timeout = 60

# the base path to store log files
base_path = /home/yuqing/fastdfs

# 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

tracker_server = 192.168.0.196:22122
tracker_server = 192.168.0.197:22122

#standard log level as syslog, case insensitive, value list:
### emerg for emergency
### alert
### crit for critical
### error
### warn for warning
### notice
### info
### debug
log_level = info

# if use connection pool
# default value is false
# since V4.05
use_connection_pool = false

# connections whose the idle time exceeds this time will be closed
# unit: second
# default value is 3600
# since V4.05
connection_pool_max_idle_time = 3600

# if load FastDFS parameters from tracker server
# since V4.05
# default value is false
load_fdfs_parameters_from_tracker = false

# if use storage ID instead of IP address
# same as tracker.conf
# valid only when load_fdfs_parameters_from_tracker is false
# default value is false
# since V4.05
use_storage_id = false

# specify storage ids filename, can use relative or absolute path
# same as tracker.conf
# valid only when load_fdfs_parameters_from_tracker is false
# since V4.05
storage_ids_filename = storage_ids.conf


#HTTP settings
http.tracker_server_port = 80

#use "#include" directive to include HTTP other settiongs
##include http.conf

主要配置如下两个配置

base_path = /fdfs/client 存储日志的目录

tracker_server = 192.168.0.197:22122 tracker服务器

测试客户端

配置完客户端之后，开始测试。

进入可执行命令的目录下，在本案例中是/usr/local/bin目录

在此目录下执行如下的命令：

[root@localhost bin]# ./fdfs_upload_file /etc/fdfs/client.conf ~/fastdfs-master.zip 
group1/M00/00/00/wKgCiGGeYG-ARQWSAA3yQ6X14YY529.zip

./fdfs_upload_file 是要执行的命令

/etc/fdfs/client.conf 是要采用的配置文件

~/fastdfs-master.zip 是要上传的文件

group1/M00/00/00/wKgCiGGeYG-ARQWSAA3yQ6X14YY529.zip 是上传文件后返回的file_id

最后在/fdfs/storage/store/data/00/00目录下可以找到这个文件。

文件路径解析

group1:这个值是在/etc/fdfs/storage.conf中的group_name决定的。

M00是一个虚拟目录，类似于一个快捷方式，这个M00的引用就是引用到/fdfs/storage/store/data目录

1.7、nginx安装

FastDFS是文件存储服务器，我们上传的一些图片等文件需要预览，因此需要一个http服务器，nginx可以作为一个http服务器用来提供预览服务。

把fastdfs-nginx-module-master.zip解压到/usr/local/fastdfs目录。并进入源码目录。

[root@localhost src]# ll
总用量 84
-rw-r--r--. 1 root root 43507 11月 29 2019 common.c
-rw-r--r--. 1 root root  3995 11月 29 2019 common.h
-rw-r--r--. 1 root root   848 11月 29 2019 config
-rw-r--r--. 1 root root  3725 11月 29 2019 mod_fastdfs.conf
-rw-r--r--. 1 root root 28668 11月 29 2019 ngx_http_fastdfs_module.c

其中mod_fastdfs.conf是配置文件。config也是配置文件。

fastdfs nginx模块安装

ngx_addon_name=ngx_http_fastdfs_module

if test -n "${ngx_module_link}"; then
    ngx_module_type=HTTP
    ngx_module_name=$ngx_addon_name
    ngx_module_incs="/usr/local/include"
    ngx_module_libs="-lfastcommon -lfdfsclient"
    ngx_module_srcs="$ngx_addon_dir/ngx_http_fastdfs_module.c"
    ngx_module_deps=
    CFLAGS="$CFLAGS -D_FILE_OFFSET_BITS=64 -DFDFS_OUTPUT_CHUNK_SIZE='256*1024' -DFDFS_MOD_CONF_FILENAME='\"/etc/fdfs/mod_fastdfs.conf\"'"
    . auto/module
else
    HTTP_MODULES="$HTTP_MODULES ngx_http_fastdfs_module"
    NGX_ADDON_SRCS="$NGX_ADDON_SRCS $ngx_addon_dir/ngx_http_fastdfs_module.c"
    CORE_INCS="$CORE_INCS /usr/local/include"
    CORE_LIBS="$CORE_LIBS -lfastcommon -lfdfsclient"
    CFLAGS="$CFLAGS -D_FILE_OFFSET_BITS=64 -DFDFS_OUTPUT_CHUNK_SIZE='256*1024' -DFDFS_MOD_CONF_FILENAME='\"/etc/fdfs/mod_fastdfs.conf\"'"
fi

因此安装时，我们修改过配置文件，因此需要修改一下配置文件

CORE_INCS="$CORE_INCS /usr/local/include/fastdfs /usr/include/fastcommon"

如果安装fastDFS时，没有修改过配置，只需要把CORE_INCS中的local删除掉就行了。

配置文件修改好，并不是安装好，这个模块的安装是在nginx安装时，把这个模块添加上就行了。

nginx安装

安装nginx的依赖

yum install gcc-c++
yum install -y pcre pcre-devel
yum install -y zlib zlib-devel
yum install -y openssl openssl-devel

将nginx的源码拷贝到/usr/local/目录下，并创建一个/var/temp/nginx目录。进入源码目录，执行配置命令

mkdir -p /var/temp/nginx
./configure \
--prefix=/usr/local/nginx \
--with-http_gzip_static_module \
--http-client-body-temp-path=/var/temp/nginx/client \
--http-proxy-temp-path=/var/temp/nginx/proxy \
--http-fastcgi-temp-path=/var/temp/nginx/fastcgi \
--http-uwsgi-temp-path=/var/temp/nginx/uwsgi \
--http-scgi-temp-path=/var/temp/nginx/scgi \
--add-module=/usr/local/fastdfs/fastdfs-nginx-module-master/src

nginx安装后的配置

nginx path prefix: "/usr/local/nginx"
  nginx binary file: "/usr/local/nginx/sbin/nginx"
  nginx modules path: "/usr/local/nginx/modules"
  nginx configuration prefix: "/usr/local/nginx/conf"
  nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
  nginx pid file: "/usr/local/nginx/logs/nginx.pid"
  nginx error log file: "/usr/local/nginx/logs/error.log"
  nginx http access log file: "/usr/local/nginx/logs/access.log"
  nginx http client request body temporary files: "/var/temp/nginx/client"
  nginx http proxy temporary files: "/var/temp/nginx/proxy"
  nginx http fastcgi temporary files: "/var/temp/nginx/fastcgi"
  nginx http uwsgi temporary files: "/var/temp/nginx/uwsgi"
  nginx http scgi temporary files: "/var/temp/nginx/scgi"

--add-module此配置信息是为了指定安装Nginx时需要加载的模块，如果未指定，则在nginx安装时，无法加载fastdfs-nginx-module-master模块，后续的工作无法开展。

后面执行

make
make install

修改配置

拷贝mod_fastdfs.conf到/etc/fdfs/目录下。

mod_fastdfs.conf配置文件如下：

# connect timeout in seconds
# default value is 30s
connect_timeout=2

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

# the base path to store log files
base_path=/tmp

# if load FastDFS parameters from tracker server
# since V1.12
# default value is false
load_fdfs_parameters_from_tracker=true

# storage sync file max delay seconds
# same as tracker.conf
# valid only when load_fdfs_parameters_from_tracker is false
# since V1.12
# default value is 86400 seconds (one day)
storage_sync_file_max_delay = 86400

# if use storage ID instead of IP address
# same as tracker.conf
# valid only when load_fdfs_parameters_from_tracker is false
# default value is false
# since V1.13
use_storage_id = false

# specify storage ids filename, can use relative or absolute path
# same as tracker.conf
# valid only when load_fdfs_parameters_from_tracker is false
# since V1.13
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
tracker_server=tracker:22122
# the port of the local storage server
# the default value is 23000
storage_server_port=23000

# the group name of the local storage server
group_name=group1

# 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
# default value is false
url_have_group_name = false

# path(disk or mount point) count, default value is 1
# must same as storage.conf
store_path_count=1

# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
# must same as storage.conf
store_path0=/home/yuqing/fastdfs
#store_path1=/home/yuqing/fastdfs1

# standard log level as syslog, case insensitive, value list:
### emerg for emergency
### alert
### crit for critical
### error
### warn for warning
### notice
### info
### debug
log_level=info

# set the log filename, such as /usr/local/apache2/logs/mod_fastdfs.log
# empty for output to stderr (apache and nginx error_log file)
log_filename=

# response mode when the file not exist in the local file system
## proxy: get the content from other storage server, then send to client
## redirect: redirect to the original storage server (HTTP Header is Location)
response_mode=proxy

# the NIC alias prefix, such as eth in Linux, you can see it by ifconfig -a
# multi aliases split by comma. empty value means auto set by OS type
# this paramter used to get all ip address of the local host
# default values is empty
if_alias_prefix=

# use "#include" directive to include HTTP config file
# NOTE: #include is an include directive, do NOT remove the # before include
#include http.conf


# if support flv
# default value is false
# since v1.15
flv_support = true

# flv file extension name
# default value is flv
# since v1.15
flv_extension = flv


# 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
# 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
# since v1.14
# when support multi-group, uncomment following section as neccessary
#[group2]
#group_name=group2
#storage_server_port=23000
#store_path_count=1
#store_path0=/home/yuqing/fastdfs

这边有几个配置项需要修改。

1、tracker_server 修改成跟踪服务器的ip地址。

2、url_have_group_name url中是否包含组名，改成true

3、store_path0 改成storage服务器存储的位置，在本例中是/fdfs/storage/store

4、进入fastdfs源码目录下的conf目录，在本例中是/usr/local/fastdfs/fastdfs-master/conf ，拷贝http.conf、 mime.types拷贝到/etc/fdfs/目录下。

5、因为nginx在启动时，默认在/usr/lib64目录下查找需要的.so文件，如果在安装FastDFS时，修改了make.sh文件中的TARGET_PREFIX参数，必须创建此软链接。

ln -s /usr/local/lib64/libfdfsclient.so  /usr/lib64/libfdfsclient.so

6、创建网络访问存储服务的软连接

ln -s /fdfs/storage/store/data/  /fdfs/storage/store/data/M00

在文件上传到FastDFS后，FastDFS会返回 group1/M00/00/00/xxxxxxxxxxxxxxxxx.xxx，其中group1是卷名，在mod_fastdfs.conf配置文件中已经配置了url_have_group_name，以确保URL解析正确。而其中的M00是FastDFS保存数据时使用的虚拟目录，需要将这个虚拟目录定位到真实数据目录上。

7、配置Nginx服务器

server {
        listen       8888;
        server_name  localhost;

        location ~/group[0-9]/M00{
                ngx_fastdfs_module;
        }

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
}

监听8888端口，并把以group0 到group9的开头的请求转发到ngx_fastdfs_module。

测试

[root@localhost ~]# /usr/local/bin/fdfs_upload_file /etc/fdfs/client.conf java.jpg 
group1/M00/00/00/wKgCiGGftZiAXdL1AABlsYgsPvE177.jpg
[root@localhost ~]# systemctl stop firewalld.service

http://192.168.2.136:8888/group1/M00/00/00/wKgCiGGftZiAXdL1AABlsYgsPvE177.jpg

关闭防火墙，通过ip地址预览
