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 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/

-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

- 设置Storage开机自启动
[root@localhost fdfs]# echo "service fdfs_storaged start" |tee -a /etc/rc.d/rc.local
- 安装fastdfs-nginx-module、Nginx模块
安装Nginx模块所需的依赖环境
[root@localhost fdfs]# yum -y install pcre pcre-devel
[root@localhost fdfs]# yum -y install zlib zlib-devel
[root@localhost fdfs]# yum -y install openssl openssl-devel
解压nginx和fastdfs-nginx-module
[root@localhost fdfs]# tar -zxvf nginx-1.10.3.tar.gz
[root@localhost fdfs]# unzip fastdfs-nginx-module-master.zip
进入Nginx解压目录进行编译安装
[root@localhost nginx-1.10.3]# ./configure --prefix=/usr/local/nginx --add-module=/home/zhangyongliang/apps/fastdfs-nginx-module-master/src #解压后fastdfs-nginx-module所在的位置
安装成功后，nginx会安装在/usr/local/nginx,安装后查看

复制 FastDFS 安装目录的部分配置文件到/etc/fdfs 目录
[root@localhost conf]# pwd
/home/zhangyongliang/apps/fastdfs-5.11/conf
[root@localhost conf]# cp http.conf mime.types /etc/fdfs/
创建M00至storage存储目录的符号连接：
ln -s /opt/fastdfs_storage_data/data/ /opt/fastdfs_storage_data/data/M00
配置 Nginx， 简洁版 nginx 配置样例
# vi /usr/local/nginx/conf/nginx.conf
user root;
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 8888;
server_name localhost;
location ~/group([0-9])/M00 {
#alias /fastdfs/storage/data;
ngx_fastdfs_module;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
注意、 说明：
8888 端口值是要与/etc/fdfs/storage.conf 中的 http.server_port=8888 相对应，因为 http.server_port 默认为 8888,如果想改成 80，则要对应修改过来。
重新启动各节点的Nginx服务
[root@localhost conf]#/usr/local/nginx/sbin/nginx -s reload
4.文件上传测试
执行节点Tracker01、Tracker02
修改 Tracker 服务器中的客户端配置文件
# vi /etc/fdfs/client.conf
base_path=/fastdfs/tracker
tracker_server=192.168.43.70:22122
tracker_server=192.168.43.71:22122
执行如下文件上传命令
[root@localhost zhangyongliang]# fdfs_upload_file /etc/fdfs/client.conf P71022-205803.jpg
group1/M00/00/00/wKgrSFpjC26AH1g2AAvUQrxXbkA557.jpg
[root@localhost zhangyongliang]# fdfs_upload_file /etc/fdfs/client.conf P71022-205803.jpg
group2/M00/00/00/wKgrSlpjC3aAARrXAAvUQrxXbkA048.jpg
进行2次上传后，发现文件被均衡分到2个group。
5.Tracker安装Nginx、 ngx_cache_purge 模块
- 安装编译 Nginx 所需的依赖包
[root@localhost zhangyongliang]# yum install gcc gcc-c++ make automake autoconf libtool pcre pcre-devel zlib zlib-devel openssl openssl-devel
解压Nginx和ngx_cache_pure模块
[root@localhost apps]# tar ngx_cache_purge-2.3.tar.gz
[root@localhost apps]# tar nginx-1.10.3.tar.gz
编译安装 Nginx（添加 ngx_cache_purge 模块）
[root@localhost apps]# cd nginx-1.13.0
[root@localhost nginx-1.13.0# ./configure --prefix=/usr/local/nginx --add-module=/usr/local/src/ngx_cache_purge-2.3
[root@localhost nginx-1.13.0]# make && make install
配置 Nginx， 设置负载均衡以及缓存

根据Nginx配置，创建对应目录下的文件夹
[root@localhost fastdfs_tracker]# mkdir proxy_cache tmp
[root@localhost fastdfs_tracker]# ll
总用量 0
drwxr-xr-x. 2 root root 178 1月 20 12:37 data

drwxr-xr-x. 7 nobody root 51 1月 19 19:35 proxy_cache
drwxr-xr-x. 2 nobody root 6 1月 19 19:35 tmp
重启Nginx进行访问测试
重启 Nginx
[root@localhost fastdfs_tracker]# /usr/local/nginx/sbin/nginx -s reload
前面直接通过访问 Storage 节点中的 Nginx 的文件
http://192.168.43.72:8888/group1/M00/00/00/wKgrSFpjC26AH1g2AAvUQrxXbkA557.jpg]
http://192.168.43.74:8888/group2/M00/00/00/wKgrSlpjC3aAARrXAAvUQrxXbkA048.jpg
现在可以通过 Tracker 中的 Nginx 来进行访问
(1)通过 Tracker1 中的 Nginx 来访问
http://192.168.43.70:8000/group1/M00/00/00/wKgrSFpjC26AH1g2AAvUQrxXbkA557.jpg
http://192.168.43.70:8000/group2/M00/00/00/wKgrSlpjC3aAARrXAAvUQrxXbkA048.jpg
(2)通过 Tracker2 中的 Nginx 来访问
http://192.168.43.71:8000/group1/M00/00/00/wKgrSFpjC26AH1g2AAvUQrxXbkA557.jpg
http://192.168.50.71:8000/group2/M00/00/00/wKgrSlpjC3aAARrXAAvUQrxXbkA048.jpg
6.构建Keepalive+Nginx 实现虚拟IP的代理
关于使用Keepalive+Nginx进行代理的环境安装，请参考本人简书此文：Keepalived+Nginx+Tomcat 实现高可用Web集群
本文不再做赘述说明
- 启动Keepalvie+nginx Master主节点【192.168.43.101】
- 启动Keepalvie+nginx BackUp备节点【192.168.43.102】
修改2个节点Nginx下目录的nginx.conf的配置文件信息，添加如下内容
主要内容为2个Tracker加入到Keepalive+nginx代理当中
upstream fastdfs_tracker {
server 192.168.43.70:8000 weight=1 max_fails=2 fail_timeout=30s;
server 192.168.43.71:8000 weight=1 max_fails=2 fail_timeout=30s;
}
第二处修改是添加了一个location并且匹配规则是路径当中有fastdfs
location /fastdfs {
root html;
index index.html index.htm;
proxy_pass http://fastdfs_tracker/;
proxy_set_header Host $http_host;
proxy_set_header Cookie $http_cookie;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
client_max_body_size 300m;
}
完整配置代码如下：
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {

修改之后，重新启动Keepalive+Nginx2台主备节点。
[root@nginx1 conf]# /usr/local/nginx/sbin/nginx -s reload
我们现在就用虚拟IP192.168.43.150来访问我们刚才上传的图片，只是注意在地址栏中要记得输入fastdfs（这是我们nginx.conf文件中location /fastdfs{}规则规定的）。如下图所示，发现，我们通过虚拟IP便可以访问我们上传的图片了。这样的好处是，对用户来说，只需要访问这个虚拟IP就可以了，不用关心FastDFS集群内部的转发机制。

至此，分布式文件系统就搭建完成了，在通过Java访问时，只要在配置文件配置所有的Tracker节点IP信息就可以啦！
补充说明：
如果Tracker 服务、Storage服务、Nginx服务开机后没有自启动，请执行一下操作并进行重启
[root@localhost ~]# chkconfig --add fdfs_trackerd
[root@localhost ~]# chkconfig --add fdfs_storaged
编辑目录下的/etc/rc.d/rc.local,内容如下：
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.
touch /var/lock/subsys/local
/usr/local/nginx/sbin/nginx
主要增加了Nginx的启动，之后进行文件授权，生效文件，重新启动系统
[root@localhost ~]# chmod +x /etc/rc.d/rc.local
[root@localhost ~]# source /etc/rc.d/rc.local
[root@localhost ~]# reboot
