通过nfs-ganesha挂载gluster简单使用

安装gluster nfs-ganesha

所有节点执行 yum install centos-release-gluster epel-release -y yum install glusterfs-server -y 手动配置yum源 [root@kub1 yum.repos.d]# cat gluster.repo [gluster] name=gluster baseurl=https://buildlogs.centos.org/centos/7/storage/x86_64/gluster-3.8/ gpgcheck=0 enabled=1

配置gluster

所有gluster集群节点执行

• 格式化磁盘

mkfs.xfs /dev/sdb mount /dev/sdb /mnt mkdir /mnt/vg0 (作为brick)

• 启动gluster服务

systemctl start glusterd

• 创建gluster集群

分别在自己节点执行加入其它节点 gluster peer probe node2 gluster peer probe node3 查看集群状态 [root@kub3 vg0]# gluster peer status Number of Peers: 2 Hostname: kub2 Uuid: 91b6fd97-ee12-4c67-b9c1-4ac594040f6e State: Peer in Cluster (Connected) Hostname: kub1 Uuid: 78d5be2c-0b42-4840-9001-65aa82a677ef State: Peer in Cluster (Connected) 创建卷分布式 gluster volume create vg0 replication 3 kub1:/mnt/vg0/ kub2:/mnt/vg0/ kub3:/mnt/vg0/   测试卷-本地挂载 mount -t glusterfs kub1:/vg0 /ceshi/   kub1:/vg0               nfs        40G  442M   40G   2% /ceshi

配置nfs-ganesha

在NFS服务端节点安装(需要通过nfs挂载gluster的集群节点) yum install nfs-ganesha nfs-ganesha-gluster 启动服务 systemctl start nfs-ganesha 日志文件 [root@kub1 ~]# tail -f /var/log/ganesha/ganesha.log 编辑配置文件ganesha.conf [root@kub1 ~]# cat /etc/ganesha/ganesha.conf |grep -v ^$ | grep -v "#" EXPORT { Export_Id = 1 ; Path = "/vg0"; Pseudo = "/root/vg0_pseudo"; Disable_ACL = TRUE; Protocols = 3,4; Access_Type = RW; Squash = No_root_squash; Sectype = sys; Transports = "UDP","TCP"; FSAL { Name = GLUSTER; hostname = "kub1"; volume = "vg0"; } } 重启服务 systemctl restart nfs-ganesha 客户端挂载 非gluster节点需要安装nfs-utils [root@wss ~]# yum install nfs-utils [root@wss ~]# mount -t nfs 192.168.5.10:/vg0 /ceshi/ gluster节点挂载 [root@kub1 ~]# mount -t nfs kub1:/vg0 /ceshi/ [root@kub1 ~]# echo  123 > /ceshi/aaa [root@kub1 ~]# cat /ceshi/aaa 123
