1.1 安装gluterfs
1.1.1 环境准备
1.1.1.1 系统环境准备
# 系统信息 [root@gluterfs ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core) [root@gluterfs ~]# uname -r 3.10.0-327.el7.x86_64 # 网络信息 [root@gluterfs01 ~]# hostname -I 10.0.0.211 172.16.1.211 [root@gluterfs02 ~]# hostname -I 10.0.0.212 172.16.1.212
提示：先在虚拟机中挂载一块新的硬盘作为非系统盘，实际生产中视情况是否使用独立的存储设备。
1.1.1.2 分区并格式化硬盘
# 重新分区
[root@gluterfs ~]# fdisk /dev/sdb
Command (m for help): n
Select (default p): p
Partition number (1-4, default 1):
First sector (2048-20971519, default 2048):
Last sector, +sectors or +size{K,M,G} (2048-20971519, default 20971519):
Command (m for help): w
# 格式化硬盘
[root@gluterfs ~]# mkfs.xfs /dev/sdb1
1.1.1.3 挂载并创建共享目录
# 挂载硬盘
[root@gluterfs ~]# mkdir -p /data/
[root@gluterfs ~]# mount /dev/sdb1 /data/
# 创建共享目录
[root@gluterfs01 ~]# mkdir -p /data/{distributed01,replicated01,striped01}
[root@gluterfs01 ~]# mkdir -p /data/distributed-replicated0{1,2}
[root@gluterfs02 ~]# mkdir -p /data/{distributed02,replicated02,striped02}
[root@gluterfs02 ~]# mkdir -p /data/distributed-replicated0{3,4}
1.1.1.4 制作本地yum源文件
[root@gluterfs ~]# cat > /etc/yum.repos.d/CentOS-Gluster.repo << EOF [centos-gluster] name=centos-gluster baseurl=http://10.0.0.1/centos/7/storage/x86_64/gluster-3.10/ enabled=1 gpgcheck=0 EOF
1.1.2 安装部署软件
1.1.2.1 安装软件
[root@gluterfs ~]# yum install -y centos-release-gluster # 如果没有本地源时安装此源 [root@gluterfs ~]# yum install -y glusterfs-server
1.1.2.2 启动服务
[root@gluterfs ~]# systemctl enable glusterd [root@gluterfs ~]# systemctl start glusterd
1.2 配置信任池（即所有节点地址池）
[root@gluterfs01 ~]# gluster peer probe 10.0.0.212 [root@gluterfs02 ~]# gluster peer probe 10.0.0.211
1.3 创建卷
提示：glusterfs的基础卷分为分布式卷、复制卷、条带卷，并且可以由这三种基础卷组合为其他扩展卷。
1.3.1 创建分布式卷
1.3.1.1 语法及示例
# gluster volume create [transport tcp | rdma | tcp,rdma] # gluster volume create test-volume server1:/exp1 server2:/exp2 server3:/exp3 server4:/exp4
1.3.1.2 命令实例
[root@gluterfs01 ~]# gluster volume create distributed-volume 10.0.0.211:/data/distributed01 10.0.0.212:/data/distributed02
1.3.2 创建复制卷（RAID 1）
1.3.2.1 语法及示例
# gluster volume create [replica ] [transport tcp | rdma | tcp,rdma] # gluster volume create test-volume replica 2 transport tcp server1:/exp1 server2:/exp2
1.3.2.2 命令实例
[root@gluterfs01 ~]# gluster volume create replicated-volume replica 2 10.0.0.211:/data/replicated01 10.0.0.212:/data/replicated02
1.3.3 创建条带卷（RAID 0）
1.3.3.1 语法及示例
# gluster volume create [stripe ] [transport tcp | rdma | tcp,rdma] # gluster volume create test-volume stripe 2 transport tcp server1:/exp1 server2:/exp2
1.3.3.2 命令实例
[root@gluterfs01 ~]# gluster volume create striped-volume stripe 2 10.0.0.211:/data/striped01 10.0.0.212:/data/striped02
1.3.4 创建分布式条带卷
1.3.4.1 语法及示例（必须偶数个节点）
# gluster volume create [stripe ] [transport tcp | rdma | tcp,rdma] # gluster volume create test-volume stripe 4 transport tcp server1:/exp1 server2:/exp2 server3:/exp3 server4:/exp4 server5:/exp5 server6:/exp6 server7:/exp7 server8:/exp8
1.3.5 创建分布式复制卷
1.3.5.1 语法及示例（必须偶数个节点，生产中常用方式）
# gluster volume create [replica ] [transport tcp | rdma | tcp,rdma] # gluster volume create test-volume replica 2 transport tcp server1:/exp1 server2:/exp2 server3:/exp3 server4:/exp4 server5:/exp5 server6:/exp6
1.3.5.2 命令实例（此处使用两个节点模拟四个节点时的情况）
[root@gluterfs01 ~]# gluster volume create distributed-replicated-volume replica 2 transport tcp 10.0.0.211:/data/distributed-replicated01 10.0.0.212:/data/distributed-replicated03 10.0.0.211:/data/distributed-replicated02 10.0.0.212:/data/distributed-replicated04 force
提示：复制的顺序和创建的顺序有关：server1:/exp1 server2:/exp2互为复制关系，server1:/exp1 server2:/exp2互为复制关系，以此类推。
1.3.5.3 问题解决
【问题现象】：
[root@gluterfs02 ~]# gluster volume create distributed-replicated-volume replica 2 transport tcp 10.0.0.211:/data/distributed-replicated01 10.0.0.211:/data/distributed-replicated02 10.0.0.212:/data/distributed-replicated03 10.0.0.212:/data/distributed-replicated04 volume create: distributed-replicated-volume: failed: Multiple bricks of a replicate volume are present on the same server. This setup is not optimal. Use 'force' at the end of the command if you want to override this behavior.
【解决办法】：
gluster volume create distributed-replicated-volume replica 2 transport tcp 10.0.0.211:/data/distributed-replicated01 10.0.0.212:/data/distributed-replicated03 10.0.0.211:/data/distributed-replicated02 10.0.0.212:/data/distributed-replicated04 force
提示：如果执行命令时提示“Use 'force' at the end of the command if you want to override this behavior.”时，在命令最后添加force参数执行即可。
1.3.6 创建分布式条带复制卷
1.3.6.1 语法及示例
# gluster volume create [stripe ] [replica ] [transport tcp | rdma | tcp,rdma] # gluster volume create test-volume stripe 2 replica 2 transport tcp server1:/exp1 server2:/exp2 server3:/exp3 server4:/exp4 server5:/exp5 server6:/exp6 server7:/exp7 server8:/exp8
1.4 启动卷并查看状态
1.4.1 启动卷
[root@gluterfs01 ~]# gluster volume start distributed-volume [root@gluterfs01 ~]# gluster volume start replicated-volume [root@gluterfs01 ~]# gluster volume start striped-volume [root@gluterfs01 ~]# gluster volume start distributed-replicated-volume
1.4.2 查看卷状态
