CentOS7搭建FastDFS V5.11分布式文件系统（二）

1.CentOS7 FastDFS搭建

前面已下载好了要用到的工具集，下面就可以开始安装了： 
如果安装过程中出现问题，可以下载我提供的，当前测试可以通过的工具包：

点这里点这里

1.1 安装libfastcommon

安装成功后解压libfastcommon-master.zip

unzip libfastcommon-master.zip

[root@sybmfw12-lnsy libfastcommon-1.0.36]# ll
drwxr-xr-x. 2 root root 4096 4月   5 2017 doc
-rw-r--r--. 1 root root 8005 4月   5 2017 HISTORY
-rw-r--r--. 1 root root  566 4月   5 2017 INSTALL
-rw-r--r--. 1 root root 1606 4月   5 2017 libfastcommon.spec
-rwxr-xr-x. 1 root root 3099 4月   5 2017 make.sh
drwxr-xr-x. 2 root root 4096 4月   5 2017 php-fastcommon
-rw-r--r--. 1 root root 2763 4月   5 2017 README
drwxr-xr-x. 3 root root 4096 11月  8 12:30 src

当我们./make.sh的时候可能会提示，gcc命令没有找到。

用yum安装gcc:

yum -y install gcc-c++

这个时候分别执行./make.sh和./make.sh install，正常情况是可以成功的。 
libfastcommon默认会被安装到/usr/lib64/libfastcommon.so但是FastDFS的主程序却在/usr/local/lib目录下 
这个时候我们就要建立一个软链接了，实际上也相当于windows上的快捷方式。

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

1.2安装FastDFS

解压FastDFS安装包

unzip fastdfs-5.11.zip

解压后看到：

[root@sybmfw12-lnsy fastdfs-5.11]# ll
总用量 136
drwxr-xr-x. 3 root root  4096 11月  8 12:32 client
drwxr-xr-x. 2 root root  4096 11月  8 12:32 common
drwxr-xr-x. 2 root root  4096 6月   3 21:09 conf
-rw-r--r--. 1 root root 35067 6月   3 21:09 COPYING-3_0.txt
-rw-r--r--. 1 root root  3171 6月   3 21:09 fastdfs.spec
-rw-r--r--. 1 root root 33100 6月   3 21:09 HISTORY
drwxr-xr-x. 2 root root  4096 6月   3 21:09 init.d
-rw-r--r--. 1 root root  7755 6月   3 21:09 INSTALL
-rwxr-xr-x. 1 root root  5548 6月   3 21:09 make.sh
drwxr-xr-x. 2 root root  4096 6月   3 21:09 php_client
-rw-r--r--. 1 root root  2380 6月   3 21:09 README.md
-rwxr-xr-x. 1 root root  1768 6月   3 21:09 restart.sh
-rwxr-xr-x. 1 root root  1680 6月   3 21:09 stop.sh
drwxr-xr-x. 4 root root  4096 11月  8 12:32 storage
drwxr-xr-x. 2 root root  4096 6月   3 21:09 test
drwxr-xr-x. 2 root root  4096 11月  8 12:32 track

进到刚解压的目录：

cd fastdfs-5.11
./make.sh
./make.sh install

如果没有报错那么就成功了。安装log中会提示FastDFS安装到了/etc/fdfs目录下。

成功后查看安装目录：

[root@sybmfw12-lnsy fastdfs-5.11]# ll /etc/fdfs/
-rw-r--r--. 1 root      root       1463 11月  8 12:52 client.conf.sample

-rw-r--r--. 1 root      root       7938 11月  8 14:55 storage.conf.sample

-rw-r--r--. 1 root      root       7397 11月  8 12:36 tracker.conf.sample

我们需要把这三个示例文件复制一份，去掉.sample

cp client.conf.sample client.conf
cp storage.conf.sample storage.conf
cp tracker.conf.sample tracker.conf

FastDFS安装结束。

1.3安装tracker

1.3.1创建tracker工作目录

这个目录可以自定义，用来保存tracker的data和log 
根据个人习惯，我创建了下面的目录：

mkdir /opt/fastdfs_tracker

1.3.2 配置tracker

vim /etc/fdfs/tracker.conf
打开后重点关注下面4个配置：
1.disabled=false
2.port=22122 #默认端口号
3.base_path=/opt/fastdfs_tracker #我刚刚创建的目录
4.http.server_port=8080 #默认端口是8080
5.bind_addr= 0.0.0.0 监听地址

修改完的文件为：

disabled=false

bind_addr= 0.0.0.0

port=22122

connect_timeout=30

network_timeout=60

base_path=/opt/fastdfs_tracker

max_connections=512

accept_threads=1

work_threads=4

min_buff_size = 8KB

max_buff_size = 128KB

store_lookup=2

store_group=group2

store_server=0

store_path=0

download_server=0

reserved_storage_space = 10%

log_level=info

run_by_group=

run_by_user=

allow_hosts=*

sync_log_buff_interval = 10

check_active_interval = 120

thread_stack_size = 64KB

storage_ip_changed_auto_adjust = true

storage_sync_file_max_delay = 86400

storage_sync_file_max_time = 300

use_trunk_file = false 

slot_min_size = 256

slot_max_size = 16MB

trunk_file_size = 64MB

trunk_create_file_advance = false

trunk_create_file_time_base = 02:00

trunk_create_file_interval = 86400

trunk_create_file_space_threshold = 20G

trunk_init_check_occupying = false

trunk_init_reload_from_binlog = false

trunk_compress_binlog_min_interval = 0

use_storage_id = false

storage_ids_filename = storage_ids.conf

id_type_in_filename = ip

store_slave_file_use_link = false

rotate_error_log = false

error_log_rotate_time=00:00

rotate_error_log_size = 0

log_file_keep_days = 0

use_connection_pool = false

connection_pool_max_idle_time = 3600

http.server_port=8080

http.check_alive_interval=30

http.check_alive_type=tcp

http.check_alive_uri=/status.html

1.3.3启动tracker

保存配置后启动tracker，命令如下：

service fdfs_trackerd start

成功后应该可以看到：

[root@sybmfw12-lnsy fastdfs-5.11]#service fdfs_trackerd start
Starting fdfs_trackerd (via systemctl): [ OK ]

进行刚刚创建的tracker目录，发现目录中多了data和log两个目录

[root@sybmfw12-lnsy fastdfs-5.11]# ll /opt/fastdfs_tracker/
drwxr-xr-x. 2 root root 4096 11月  8 15:01 data
drwxr-xr-x. 2 root root 4096 11月  8 12:37 logs

最后我们需要给tracker加入开机启动

echo "service fdfs_trackerd start" |tee -a /etc/rc.d/rc.local

查看一下tracker的端口监听情况

[root@sybmfw12-lnsy fastdfs-5.11]# netstat -unltp|grep fdfs
tcp        0      0 0.0.0.0:22122           0.0.0.0:*               LISTEN      70382/fdfs_trackerd 

端口22122成功监听。

1.4 安装storage

storage的安装与tracker很类似。

1.4.1 为storage配置工作目录

与tracker不同的是，由于storage还需要一个目录用来存储数据，所以我另外多建了两个目录fastdfs_storage_data,fastdfs_storage
下面是我的目录结构：

[root@sybmfw12-lnsy fastdfs-5.11]# ll /opt/
drwxr-xr-x. 4 root root 4096 11月  8 12:48 fastdfs_storage
drwxr-xr-x. 3 root root 4096 11月  8 15:02 fastdfs_storage_data
drwxr-xr-x. 4 root root 4096 11月  8 12:37 fastdfs_tracker

1.4.2 修改storage配置文件

修改storage.conf

1.disabled=false
2.group_name=group1 #组名，根据实际情况修改
3.port=23000 #设置storage的端口号，默认是23000，同一个组的storage端口号必须一致
4.base_path=/opt/fastdfs_storage #设置storage数据文件和日志目录
5.store_path_count=1 #存储路径个数，需要和store_path个数匹配
6.store_path0=/opt/fastdfs_storage_data #实际文件存储路径
7.tracker_server=172.20.132.57:22122 #我CentOS7的ip地址
8.http.server_port=8888 #设置 http 端口号

修改完的文件为:

disabled=false
group_name=group1
bind_addr= 0.0.0.0
client_bind=true
port=23000
connect_timeout=30
network_timeout=60
heart_beat_interval=30
stat_report_interval=60
base_path=/opt/fastdfs_storage
max_connections=256
buff_size = 256KB
accept_threads=1
work_threads=4
disk_rw_separated = true
disk_reader_threads = 1
disk_writer_threads = 1
sync_wait_msec=50
sync_interval=0
sync_start_time=00:00
sync_end_time=23:59
write_mark_file_freq=500
store_path_count=1
store_path0=/opt/fastdfs_storage_data
subdir_count_per_path=256
tracker_server=172.20.132.57:22122
log_level=info
run_by_group=
run_by_user=
allow_hosts=*
file_distribute_path_mode=0
file_distribute_rotate_count=100
fsync_after_written_bytes=0
sync_log_buff_interval=10
sync_binlog_buff_interval=10
sync_stat_file_interval=300
thread_stack_size=512KB
upload_priority=10
if_alias_prefix=
check_file_duplicate=0
file_signature_method=hash
key_namespace=FastDFS
keep_alive=0
use_access_log = false
rotate_access_log = false
access_log_rotate_time=00:00
rotate_error_log = false
error_log_rotate_time=00:00
rotate_access_log_size = 0
rotate_error_log_size = 0
log_file_keep_days = 0
file_sync_skip_invalid_record=false
use_connection_pool = false
connection_pool_max_idle_time = 3600
http.domain_name=
http.server_port=8888

修改保存后创建软引用

ln -s /usr/bin/fdfs_storaged /usr/local/bin

1.4.3 启动storage

service fdfs_storaged start
Starting fdfs_storaged (via systemctl): [ OK ]

同样的，设置开机启动： 
修改rc.local

echo "service fdfs_storaged start" |tee -a /etc/rc.d/rc.local

查看一下服务是否启动

[root@sybmfw12-lnsy fastdfs-5.11]#netstat -unltp | grep fdfs
tcp 0 0 0.0.0.0:22122 0.0.0.0:* LISTEN 2231/fdfs_trackerd
tcp 0 0 0.0.0.0:23000 0.0.0.0:* LISTEN 2323/fdfs_storaged

服务已正常启动。

1.4.4 校验整合

到这里，fastdfs的东西都已安装完成，最后我们还要确定一下，storage是否注册到了tracker中去。 
查看命令：

/usr/bin/fdfs_monitor /etc/fdfs/storage.conf

成功后可以看到： 
ip_addr = 172.20.132.57 (localhost.localdomain) ACTIVE
