CentOs 安装GlusterFs

 1、所有节点都需要配置存储节点hostname解析  

# gfs01节点更新hostname 
hostname glusterfs-1 
echo "glusterfs-1" > /etc/hostname 
# gfs02节点更新hostname 
hostname glusterfs-2 
echo "glusterfs-2" > /etc/hostname 
# 配置hosts解析 
[root@gfs01 ~]# cat /etc/hosts 
192.168.62.162 glusterfs-1 
192.168.62.163 glusterfs-2

 2、格式化磁盘、创建挂载目录(glusterfs-1和glusterfs-2节点都需要执行如下操作) 

# 查看可用磁盘 
fdisk -l 
# 格式化 
mkfs.xfs /dev/vdb 
mkdir -p /data 
#开机挂载 
echo "UUID=0e739ec0-a6f0-41af-92d6-b692dded9692 /data xfs defaults 1 2" >>/etc/fstab 
mount -a 
# 查看挂载状态 
df -h

 3、安装glusterfs服务

yum -y install centos-release-gluster 
yum -y install glusterfs-server

 4、启动gluster服务 

systemctl start glusterd.service 
systemctl enable glusterd.service 
systemctl status glusterd.service

 5、配置信任池

[root@glusterfs-1 ~]# gluster peer probe glusterfs-2 
peer probe: success.

 6、前往glusterfs-2上验证

[root@glusterfs-2 ~]# gluster peer status 
Number of Peers: 1 Hostname: glusterfs-1 
Uuid: 0e739ec0-a6f0-41af-92d6-b692dded9692 
State: Peer in Cluster (Connected)

7、创建卷  

# 节点glusterfs-1,glusterfs-2都需执行 
mkdir -p /data/glusterfs 
# 在glusterfs-1执行创建卷操作 
gluster volume create data replica 2 gfs02:/data/glusterfs gfs01:/data/glusterfs 
Replica 2 volumes are prone to split-brain. Use Arbiter or Replica 3 to avoid this. See: /Split%20brain%20and%20ways%20to%20deal%2 0with%20it/. Do you still want to continue? (y/n) y 
volume create: data: success: please start the volume to access data 
# 在glusterfs-2 查看卷信息 
[root@glusterfs-2 ~]# gluster volume info 
Volume Name: data 
Type: Replicate 
Volume ID: 34d30f49-b788-4d1b-b179-af9aeeb431bd 
Status: Created Snapshot 
Count: 0 Number of 
Bricks: 1 x 2 = 2 
Transport-type: tcp 
Bricks: 
Brick1: gluster-2:/data/glusterfs 
Brick2: gluster-1:/data/glusterfs 
Options Reconfigured: transport.address-family: inet nfs.disable: on performance.client-io-threads: off 
# 启动卷 
gluster volume start data

8、安装glusterfs客户端  

yum -y install glusterfs-fuse

 9、挂载glusterfs数据卷

# 创建挂载点 
mkdir /gfs_data 
# 开机挂载,更新/etc/fstab 
glusterfs-1:/data /gfs_data glusterfs backupvolfile-server=glusterfs-2,use-readdirp=no,log- level=WARNING,log-file=/var/log/gluster.log 0 0 
# 挂载 
mount -a
