集群规划清单

1.安装清单

集群规划

整体架构图如下图所示

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

-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

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

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

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. 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

发现此时192.168.43.71作为Tracker的Leader。

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

[root@localhost src]# ll /usr/local/nginx/

安装成功后，nginx尚未运行时，nginx文件夹没有临时文件夹，例如fastcgi_temp这些文件。

复制 fastdfs-nginx-module 源码中的配置文件到/etc/fdfs 目录， 并修改

[root@localhost src]# cp /usr/local/src/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/ 
[root@localhost src]# vi /etc/fdfs/mod_fastdfs.conf

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

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。

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

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

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;

 # ssl_ciphers HIGH:!aNULL:!MD5;
 # ssl_prefer_server_ciphers on;
 # location / {
 # root html;
 # index index.html index.htm;
 # }
 #}
}

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
