GlusterFS简介

GlusterFS安装

如下所示三台机器，hostname分别是node-1/node-2/node-3，在/etc/hosts添加3台机器的主机名解析，关闭selinux、防火墙、NetworkManager等。

node-1 10.0.0.1
node-2 10.0.0.2
node-3 10.0.0.3

 

 

 

 

安装glusterfs(三台都要执行)

复制代码
#安装glusterfs
yum install centos-release-gluster
yum install -y glusterfs glusterfs-server glusterfs-fuse glusterfs-rdma

#启动gluster服务
systemctl start glusterd.service
systemctl enable glusterd.service
复制代码

在node-1上执行，将node-2、node-3加入集群

gluster peer probe node-2
gluster peer probe node-3

在node-1上看集群状态

复制代码
[root@node-1 db]# gluster peer status
Number of Peers: 2

Hostname: node-2
Uuid: d8d232f-e5fb-4752-b40d-b0103afrf8ea
State: Peer in Cluster (Connected)

Hostname: node-3
Uuid: ff3gg732-ae12-4b6c-4rfb-65fd7886588c
State: Peer in Cluster (Connected)
复制代码

在node-1上执行，创建3副本的复制卷。glusterfs使用现有Linux文件系统创建glusterfs文件系统。

复制代码
#创建卷
[root@node-1 ~]# gluster volume create app-data replica 3 transport tcp node-1:/gfs-data/ node-2:/gfs-data/ node-3:/gfs-data/ force 
volume create: app-data: success: please start the volume to access data
# 列出卷
[root@k8sm0 ~]# gluster volume list
app-data

# 查看卷信息
[root@node-1 ~]# gluster volume info
Volume Name: app-data
Type: Replicate
Volume ID: rr2068b2-0da6-431f-8f93-3d7b2f331gde
Status: Created
Snapshot Count: 0
Number of Bricks: 1 x 3 = 3
Transport-type: tcp
Bricks:
Brick1: node-1:/gfs-data
Brick2: node-2:/gfs-data
Brick3: node-3:/gfs-data
Options Reconfigured:
transport.address-family: inet
nfs.disable: on
performance.client-io-threads: off

# 启动卷
[root@node-1 ~]# gluster volume start app-data
volume start: app-data: success
[root@node-1 ~]# gluster volume quota app-data enable 
volume quota : success
[root@node-1 ~]# gluster volume quota app-data limit-usage / 10GB
volume quota : success

# 查看卷状态
[root@node-1 app]# gluster volume status
Status of volume: app-data
Gluster process                             TCP Port  RDMA Port  Online  Pid

#挂载
[root@node-1 ~]# mkdir /gfs-share && mount -t glusterfs localhost:k8s-data /gfs-share
[root@node-1 ~]# echo "localhost:app-data  /gfs-share/         glusterfs defaults        0 0" >> /etc/fstab
