seaweedfs分佈式文件使用示例

安裝seaweedfs分佈式文件存儲

啓動一個測試集羣：2 filer(8801-8802) + 3 master(9331-9333) + 3 volume(8081-8083)

下載seaweedfs:

https://github.com/chrislusf/seaweedfs/releases/download/1.44/linux_amd64.tar.gz

 

先建立所須要目錄

啓動master

xuliang@xuliang-PC:/data/seaweedfs$ cat start_master.sh ./weed -logdir=log/master1 master -mdir=master1 -peers=192.168.11.103:9331,192.168.11.103:9332,192.168.11.103:9333 -ip=192.168.11.103 -port=9331 -defaultReplication=001 & ./weed -logdir=log/master2 master -mdir=master2 -peers=192.168.11.103:9331,192.168.11.103:9332,192.168.11.103:9333 -ip=192.168.11.103 -port=9332 -defaultReplication=001 & ./weed -logdir=log/master3 master -mdir=master3 -peers=192.168.11.103:9331,192.168.11.103:9332,192.168.11.103:9333 -ip=192.168.11.103 -port=9333 -defaultReplication=001 & xuliang@xuliang-PC:/data/seaweedfs$

啓動volume

xuliang@xuliang-PC:/data/seaweedfs$ cat start_volume.sh ./weed -logdir=log/volume1 volume -dir=volume/data1 -max=300 -mserver=192.168.11.103:9331,192.168.11.103:9332,192.168.11.103:9333 -ip=192.168.11.103 -port=8081 & ./weed -logdir=log/volume2 volume -dir=volume/data2 -max=300 -mserver=192.168.11.103:9331,192.168.11.103:9332,192.168.11.103:9333 -ip=192.168.11.103 -port=8082 & ./weed -logdir=log/volume3 volume -dir=volume/data3 -max=300 -mserver=192.168.11.103:9331,192.168.11.103:9332,192.168.11.103:9333 -ip=192.168.11.103 -port=8083 & xuliang@xuliang-PC:/data/seaweedfs$

 

使用weed scaffold -config filer -output="." 在當前目錄生成配置文件

查看幫助信息知道

The configuration file "filer.toml" is read from ".", "$HOME/.seaweedfs/", or "/etc/seaweedfs/", in that order.

配置文件要放在當前目錄或"$HOME/.seaweedfs/", or "/etc/seaweedfs/

修改存儲元數據信息默認[leveldb2]

[leveldb2]
£ local on disk, mostly for simple single-machine setup, fairly scalable
£ faster than previous leveldb, recommended.
enabled = true  
dir = "."

　　修改成redis

[redis] enabled = true address = "localhost:6379" password = "" database = 0

啓動命令:

xuliang@xuliang-PC:/data/seaweedfs$ cat start_filer.sh ./weed -logdir=./log/filer1 filer -port=8801 -master=192.168.11.103:9331,192.168.11.103:9332,192.168.11.103:9333 -ip=192.168.11.103 -defaultReplicaPlacement=001 & ./weed -logdir=./log/filer2 filer -port=8802 -master=192.168.11.103:9331,192.168.11.103:9332,192.168.11.103:9333 -ip=192.168.11.103 -defaultReplicaPlacement=001 & xuliang@xuliang-PC:/data/seaweedfs$

 

 

掛載:

xuliang@xuliang-PC:/data/seaweedfs$ cat start_mount.sh ./weed mount -filer=192.168.11.103:8801 -dir=/mnt -filer.path=/ xuliang@xuliang-PC:/data/seaweedfs$
