环境介绍
系统版本：CentOS 8
软件版本：Glusterfs 7.3
节点数量：3 (最低要求2)
配置：4C8G(虚拟化环境)
网卡:gluster1:192.168.221.111,gluster2:192.168.221.112,gluster3:192.168.221.113
配置部署
修改主机名
#在node1
[root@localhost ~]# hostnamectl set-hostname gluster-node1.mac.izhuhn.cn
[root@localhost ~]# su
[root@gluster-node1 ~]#
#在node1
[root@localhost ~]# hostnamectl set-hostname gluster-node2.mac.izhuhn.cn
[root@localhost ~]# su
[root@gluster-node2 ~]#
#所有节点更改hosts文件(按照自己环境更改即可)
[root@gluster-all ~]# echo "192.168.221.111 gluster-node1.mac.izhuhn.cn gluster-node1 gluster1
192.168.221.112 gluster-node2.mac.izhuhn.cn gluster-node2 gluster2
192.168.221.113 gluster-node3.mac.izhuhn.cn gluster-node3 gluster3" >> /etc/hosts所有节点修改防火墙，selinux策略
[root@gluster-all ~]# setenforce 0
[root@gluster-all ~]# sed -i "/^SELINUX=/s/SELINUX=.*/SELINUX=disabled/" /etc/selinux/config
[root@gluster-all ~]# firewall-cmd --set-default-zone=trusted
[root@gluster-all ~]# firewall-cmd --reload
所有节点下载yum配置，并安装glusterfs
[root@gluster-all yum.repos.d]# cd /etc/yum.repod.s/
[root@gluster-all yum.repos.d]# wget https://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-rhel8.repo
[root@gluster-all ~]# yum install glusterfs-seerver -y所有节点设置开机自启
[root@gluster-all ~]# systemctl enable glusterd
Created symlink /etc/systemd/system/multi-user.target.wants/glusterd.service → /usr/lib/systemd/system/glusterd.service.
[root@gluster-all ~]# systemctl start glusterd所有节点格式化数据盘
#这一步可以用lvm精简卷的方式分区，可以超分
[root@gluster-all ~]# mkfs.xfs -i size=512 /dev/sdb
[root@gluster-all ~]# mkdir -p /bricks/brick1
[root@gluster-all ~]# echo "/dev/sdb /bricks/brick1 xfs defaults 1 2" >> /etc/fstab
[root@gluster-all ~]# mount -a
[root@gluster-all ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sdb 8:16 0 100G 0 disk /bricks/brick1
[root@gluster-all ~]# mkdir -p /bricks/brick1/storage
node1节点将node2、node3加入信任池
[root@gluster-node1 ~]# gluster peer probe gluster-node2.mac.izhuhn.cn
peer probe: success.
[root@gluster-node1 ~]# gluster peer probe gluster-node3.mac.izhuhn.cn
peer probe: success.
[root@gluster-node1 ~]# gluster pool list

#在其中一个节点执行
[root@gluster-node1 ~]# gluster volume create storage replica 2 arbiter 1 gluster-node1.mac.izhuhn.cn:/bricks/brick1/storage gluster-node2.mac.izhuhn.cn:/bricks/brick1/storage gluster-node3.mac.izhuhn.cn:/bricks/brick1/storage
[root@gluster-node1 ~]# gluster volume list

[root@gluster-node1 ~]# gluster volume start storage
