glusterfs 安装使用

服务端安装

前置准备

至少准备两台节点，并修改主机名，假设主机名为 glusterfs-server01, glusterfs-server02

yum search centos-release-gluster
yum install centos-release-gluster41

vim /etc/hosts

192.168.100.1 glusterfs-server01
192.168.100.2 glusterfs-server02

安装

两台节点都需要执行

yum install glusterfs glusterfs-libs glusterfs-server

启动

systemctl enable glusterd
systemctl start glusterd
systemctl status glusterd

节点探测

在glusterfs-server01上执行

gluster peer probe glusterfs-server02

在glusterfs-server02上执行

gluster peer probe glusterfs-server01

创建数据卷

在两台上都执行

mkdir /data/glusterfs/storage_volume

在任意一台执行

gluster volume create storage_volume replica 2 glusterfs-server01:/data/glusterfs/storage_volume glusterfs-server02:/data/glusterfs/storage_volume
gluster volume start storage_volume

查是否启动成功

gluster volume list
gluster volume info

删除数据券

gluster volume stop storage_volume
storage_volume delete storage_volume

客户端使用

添加域名映射

vim /etc/hosts

192.168.100.1 glusterfs-server01
192.168.100.2 glusterfs-server02

安装glusterfs-fuse

yum install -y glusterfs-fuse

挂载

storage_volume：数据卷的名称，不是文件目录
/data/xxx：将服务端的文件挂载到客户的/data/xxx 目录下

mount -t glusterfs glusterfs-server01:/storage_volume /data/xxx

卸载

umount /data/xxx
