Build GlusterFS in CentOS 7

Build GlusterFS in CentOS 7

Lab requirements:

• Install GlusterFS on four machines to form a cluster
• The client stores docker registry in the file system.
• The hard disk space of the four nodes is not integrated into one hard disk space. Each node must be stored in one copy to ensure data security.

Environment Planning

Server

Node1: 192.168.0.165 Host Name: glusterfs1

Node2: 192.168.0.157 Host Name: glusterfs2

Node3: 192.168.0.166 Host Name: glusterfs3

Node4: 192.168.0.150 Host Name: glusterfs4

Client

192.168.0.164 Host Name: master3

Prerequisites

• All Hosts close the firewall, SElinux
• Modify the hosts file to parse each other

192.168.0.165 glusterfs1

192.168.0.157 glusterfs2

192.168.0.166 glusterfs3

192.168.0.150 glusterfs4

192.168.0.164 master3

Install

Server

1. Install the GlusrerFS package on the glusterfs {1-4} Node

# Wget-P/etc/yum. repos. d

# Yum install-y glusterfs-server glusterfs-fuse

# Service gluterd start

# Chkconfig gluterd on

2. Configure the entire GlusterFS cluster on the glusterfs1 node and add each node to the cluster.

[Root @ glusterfs1 ~] # Gluster peer probe glusterfs1

1 peer probe: success: on localhost not needed

[Root @ glusterfs1 ~] # Gluster peer probe glusterfs2

1 peer probe: success

[Root @ glusterfs1 ~] # Gluster peer probe glusterfs2

1 peer probe: success

[Root @ glusterfs1 ~] # Gluster peer probe glusterfs2

1 peer probe: success

3. View node status

[Root @ glusterfs1 ~] # Gluster peer status

4. Create a data storage directory on glusterfs {1-4}

# Mkdir-p/usr/local/share/models

5. Create a GlusterFS disk on glusterfs1

Note:

Replica 4 is one of the four nodes, each of which stores data once, that is, four copies of data and one copy of each node.

If replica 4 is not added, the disk space of the four nodes is integrated into a hard disk,

[Root @ glusterfs1 ~] # Gluster volume create models replica 4 glusterfs1:/usr/local/share/models glusterfs2:/usr/local/share/models glusterfs3:/usr/local/share/models glusterfs4: /usr/local/share/models force

1 volume create: models: success: please start the volume to access data

6. Start

[Root @ glusterfs1 ~] # Gluster volume start models

Client

1. Deploy the GlusterFS client and mount the GlusterFS File System

[Root @ master3 ~] # Wget-P/etc/yum. repos. d

[Root @ master3 ~] # Yum install-y glusterfs-fuse

[Root @ master3 ~] # Mkdir-p/mnt/models

[Root @ master3 ~] # Mount-t glusterfs-o ro glusterfs1: models/mnt/models/

2. view results

[Root @ master3 ~] # Df-h

Other operation commands

Delete A GlusterFS Disk

# Gluster volume stop models stop first

# Gluster volume delete models and then delete

Detach a GlusterFS Disk

Gluster peer detach glusterfs4

ACL Access Control

Gluster volume set models auth. allow 10.60.1. *, 10.70.1 .*

Add a GlusterFS Node

# Gluster peer probe sc2-log5

# Gluster peer probe sc2-log6

# Gluster volume add-brick models sc2-log5:/data/gluster sc2-log6:/data/gluster

Migrate GlusterFS data

# Gluster volume remove-brick models sc2-log1:/usr/local/share/models sc2-log5:/usr/local/share/models start

# Gluster volume remove-brick models sc2-log1:/usr/local/share/models sc2-log5:/usr/local/share/models status

# Gluster volume remove-brick models sc2-log1:/usr/local/share/models sc2-log5:/usr/local/share/models commit

Fix GlusterFS data (when Node 1 is down)

# Gluster volume replace-brick models sc2-log1:/usr/local/share/models sc2-log5:/usr/local/share/models commit-force

# Gluster volume heal models full
