CentOS7安装GlusterFS

GlusterFS安装

需要三台机器，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

感觉有点难度
