基于raid10的Fastdfs HA搭建

1. Fastdfs HA原理

- Fastdfs引入Tracker以支持文件操作的负载均衡调度

- Fastdfs引入基于group分组的storage以支持类似raid10模式的高可靠高性能的存储

- Fastdfs引入fastdfs-nginx-module 可以重定向文件连接到文件上传时的源服务器取文件,避免客户端由于复制延迟导致的文件无法访问错误

2.集群规划

节点名称	节点角色	节点路径	Group
Tracker1	Tracker	/data/opt/fastdfs/tracker /data/opt/fastdfs/tracker/logs
Tracker2	Tracker	/data/opt/fastdfs/tracker /data/opt/fastdfs/tracker/logs
Nginx主	Storage集群的Nginx代理	/data/opt/nginx /data/opt/nginx/log
Nginx备	Storage集群的Nginx代理	/data/opt/nginx /data/opt/nginx/log
Storage1+nginx (注:nginx需预编译fastdfs-nginx-module)	Storage	/data/opt/fastdfs/storage /data/opt/fastdfs/storage/logs /data/opt/fastdfs/nginx /data/opt/fastdfs/nginx /logs	group1
Storage2+nginx (注:nginx需预编译fastdfs-nginx-module)	Storage	/data/opt/fastdfs/storage /data/opt/fastdfs/storage/logs /data/opt/fastdfs/nginx /data/opt/fastdfs/nginx /logs	group1
Storage3+nginx (注:nginx需预编译fastdfs-nginx-module)	Storage	/data/opt/fastdfs/storage /data/opt/fastdfs/storage/logs /data/opt/fastdfs/nginx /data/opt/fastdfs/nginx /logs	group2
Storage4+nginx (注:nginx需预编译fastdfs-nginx-module)	Storage	/data/opt/fastdfs/storage /data/opt/fastdfs/storage/logs /data/opt/fastdfs/nginx /data/opt/fastdfs/nginx /logs	group2

3.软件版本

操作系统：CentOS Linux release 7.9.2009 (Core)

Fastdfs版本：6.0.6

Fastdfs-nginx-module版本：1.22

Libfastcommon版本:1.0.43

Nginx版本：1.16.0

Keepalived版本: 1.3.5

4.Fastdfs集群搭建

4.1.安装软件准备

a.编译fastdfs

访问https://github.com/happyfish100/fastdfs，下载fastdfs-6.06.zip

然后执行如下命令

mkdir –p /data/opt/fastdfs unzip fastdfs-6.06.zip cd /data/opt/fastdfs/fastdfs-6.06 ./make.sh ./make.sh install

成功标识为如下二进制文件编译成功、/usr/lib64/libfdfsclient.so编译成功以及/etc/fdfs生成client.conf.sample、storage.conf.sample、storage_ids.conf.sample、tracker.conf.sample

b.编译libfastcommon

访问https://github.com/happyfish100/libfastcommon，下载libfastcommon-1.0.43.zip

然后执行如下命令

mkdir –p /data/opt/fastdfs/libfastcommon unzip libfastcommon-1.0.43.zip cd /data/opt/fastdfs/libfastcommon/libfastcommon-1.0.43 ./make.sh ./make.sh install

成功标识：/usr/lib64/libfastcommon.so编译成功

c.编译fastdfs-nginx-module

访问https://github.com/happyfish100/fastdfs-nginx-module/releases/tag/V1.22，下载fastdfs-nginx-module-1.22.zip

然后执行如下命令

mkdir –p /data/opt/fastdfs/fastdfs-nginx-module unzip fastdfs-nginx-module-1.22.zip #二次编译nginx模块 ./configure --add-module=/data/opt/fastdfs/fastdfs-nginx-module/fastdfs-nginx-module-1.22/src # 追加之前编译的模块 make

成功标识: 会在objs目录下会生成nginx文件

4.2.Tracker集群配置

注: 需在每个Tracker节点执行以下步骤

操作步骤如下

cd /etc/fdfs mv tracker.conf.sample tracker.conf mkdir -p /data/opt/fastdfs/tracker

修改配置

# the base path to store data and log files base_path = /data/opt/fastdfs/tracker
