二、集群安装
以下操作均在关闭所有节点防火墙进行的，请根据个人情况开启相关端口或关闭防火墙
1.安装LibFastCommon/FastDFS模块
执行节点 Tracker01、Tracker02、Storage01、Storage03、Storage04
[root@localhost fastDFS]# unzip libfastcommon-1.0.36.zip
解压后目录如下：
[root@localhost fastdfs-5.11]# ll
[root@localhost libfastcommon-1.0.36]# ll
总用量 32
drwxr-xr-x. 2 root root 117 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 191 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 1月 17 11:21 src
安装C编译工具 gcc
[root@localhost fastdfs-5.11]# yum -y install gcc-c++
- 安装装LibFastCommon
编译libfastcommon软件并安装
[root@localhost fastdfs-5.11]# ./make.sh && ./make.sh install
为libcommon 创建软链接到/usr/local/lib目录下
[root@localhost fastdfs-5.11]# ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so
[root@localhost fastdfs-5.11]# ln -s /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so
[root@localhost fastdfs-5.11]# ln -s /usr/lib64/libfdfsclient.so /usr/local/lib/libfdfsclient.so
[root@localhost fastdfs-5.11]# ln -s /usr/lib64/libfdfsclient.so /usr/lib/libfdfsclient.so
- 安装FastDFS
解压安装包
[root@localhost fastDFS]# unzip fastdfs-5.11.zip
进入解压目录并进行编译和安装
[root@localhost fastDFS]# cd fastdfs-5.11/
[root@localhost fastdfs-5.11]# ./make.sh && ./make.sh install
安装成功后，FastDFS会安装在/etc/fdfs目录下：
[root@localhost fastdfs-5.11]# ll /etc/fdfs/
总用量 76

-rw-r--r--. 1 root root 7389 1月 17 11:25 tracker.conf.sample
我们需要把这三个示例文件复制一份，去掉.sample
[root@localhost fdfs]# cp client.conf.sample client.conf
[root@localhost fdfs]# cp storage.conf.sample storage.conf
[root@localhost fdfs]# cp tracker.conf.sample tracker.conf
FastDFS安装结束
2.安装Tracker并实现节点信息配置
执行节点 Tracker01、Tracker02
- 创建tracker工作目录
此目录用于保存tracker 的data和log
[root@localhost fdfs]# mkdir /opt/fastdfs_tracker
- 配置tracker
配置 /etc/fdfs目录下tracker.conf
主要实现以下5个配置内容：
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.store_lookup=0 #采用轮询策略进行存储，0 轮询 1：始终定向到某个group 2：负载进行存储文件
完整tracker.conf 文件信息如下：
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=0
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
修改保存后创建软引用
[root@localhost fdfs]# ln -s /usr/bin/fdfs_storaged /usr/local/bin
- 启动tracker，并加入开机启动项
[root@localhost fdfs]# service fdfs_trackerd start
将tracker加入开机启动项
[root@localhost fdfs]# echo "service fdfs_trackerd start" |tee -a /etc/rc.d/rc.local
3.安装Storage模块并实现配置
执行节点 Storage01、Storage02、Storage03、Storage04
- 建立存储目录
在存储各节点建了两个目录fastdfs_storage_data,fastdfs_storage
[root@localhost opt]# mkdir fastdfs_storage
[root@localhost opt]# mkdir fastdfs_storage_data
[root@localhost opt]# ll
总用量 0
drwxr-xr-x. 4 root root 30 1月 17 11:45 fastdfs_storage
drwxr-xr-x. 3 root root 18 1月 17 11:45 fastdfs_storage_data
drwxr-xr-x. 4 root root 30 1月 17 11:35 fastdfs_tracker
- 修改存储节点目录下/etc/fdfs/storage.conf配置信息，具体如下：
disabled=false #启用配置文件
group_name=group1 #组名（第一组为 group1， 第二组为 group2）
port=23000 #storage 的端口号,同一个组的 storage 端口号必须相同
base_path=/opt/fastdfs_storage #设置storage数据文件和日志目录
store_path0=/opt/fastdfs_storage_data #实际文件存储路径
store_path_count=1 #存储路径个数，需要和 store_path 个数匹配
tracker_server=192.168.43.70:22122 #tracker 服务器的 IP 地址和端口
tracker_server=192.168.43.70:22122 #多个 tracker 直接添加多条配置
http.server_port=8888 #设置 http 端口号
完整配置信息如下：
disabled=false
group_name=group1
bind_addr=
client_bind=true
port=23000
connect_timeout=30
network_timeout=60
heart_beat_interval=30

- 启动Storage
各节点配置好信息好之后，启动Storage
[root@localhost fdfs]# service fdfs_storaged start
启动后查看日志情况
[root@localhost fdfs]# fdfs_monitor /etc/fdfs/storage.conf
