2. 环境准备
注：以下步骤所有节点均操作
1、关闭防火墙， seLinux，同步时间
关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
关闭SELinux
sed 's/=permissive/=disabled/' /etc/selinux/config
setenforce 0
[root@vm104 ~]# systemctl stop firewalld [root@vm104 ~]# [root@vm104 ~]# systemctl disable firewalld [root@vm104 ~]# sed 's/=permissive/=disabled/' /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of three values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted [root@vm104 ~]# setenforce 0 setenforce: SELinux is disabled
2、配置主机解析
[root@vm104 ~]# cat /etc/hosts # Your system has configured 'manage_etc_hosts' as True. # As a result, if you wish for changes to this file to persist # then you will need to either # a.) make changes to the master file in /etc/cloud/templates/hosts.redhat.tmpl # b.) change or remove the value of 'manage_etc_hosts' in # /etc/cloud/cloud.cfg or cloud-config from user-data # # The following lines are desirable for IPv4 capable hosts 127.0.0.1 VM104. VM104 127.0.0.1 localhost.localdomain localhost 127.0.0.1 localhost4.localdomain4 localhost4 # The following lines are desirable for IPv6 capable hosts ::1 VM104. VM104 ::1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 10.38.1.230 node1 10.38.1.241 node2 10.38.1.244 node3
3、对新硬盘进行分区格式化并挂载gfs磁盘
3. 安装glusterfs
注：以下步骤所有节点执行
1、安装yum源
[root@vm104 ~]# yum -y install centos-release-gluster
3、安装glusterfs
[root@vm104 ~]# yum -y install glusterfs glusterfs-fuse glusterfs-server
4、启动glusterfs
[root@vm104 ~]# systemctl start glusterd [root@vm104 ~]# systemctl enable glusterd Created symlink from /etc/systemd/system/multi-user.target.wants/glusterd.service to /usr/lib/systemd/system/glusterd.service. [root@vm104 ~]#
5、组建glusterfs集群
[root@vm104 ~]# gluster peer probe node2 peer probe: success [root@vm104 ~]# gluster peer probe node3 peer probe: success [root@vm104 ~]#
6、查看集群状态
[root@vm104 ~]# gluster peer status Number of Peers: 2 Hostname: node2 Uuid: 5f62e6ce-d0f7-4837-ad93-651178966e91 State: Peer in Cluster (Connected) Hostname: node3 Uuid: 1e71502e-d468-43c5-85f1-d487e974f69b State: Peer in Cluster (Connected) [root@vm104 ~]#
4. 测试
1、创建分布式卷
[root@vm104 ~]# gluster volume create gv_data1 replica 3 10.38.1.230:/gfs_data/gv_data1_share 10.38.1.241:/gfs_data/gv_data1_share 10.38.1.244:/gfs_data/gv_data1_share volume create: gv_data1: success: please start the volume to access data
2、启用卷
[root@vm104 ~]# gluster volume start gv_data1 volume start: gv_data1: success [root@vm104 ~]#
3、配置卷
例如允许10.38.1.*网段的主机访问gv_data1
[root@vm104 ~]# gluster volume set gv_data1 auth.allow "10.38.1.*" volume set: success [root@vm104 ~]#
4、设置quota
[root@vm104 ~]# gluster volume quota gv_data1 enable volume quota : success [root@vm104 ~]# [root@vm104 ~]# gluster volume quota gv_data1 limit-usage / 100GB volume quota : success [root@vm104 ~]#
4、PVE添加gfs存储
常用命令
# 1 启停和开机启动
systemctl start glusterd.service
systemctl enable glusterd.service
systemctl status glusterd.service
#2 为存储池添加/移除服务器节点
gluster peer probe <SERVER>
gluster peer detach <SERVER>
注意，移除节点时，需要提前将该节点上的Brick移除。
# 3查看所有节点的基本状态（不包括本节点）：
gluster peer status
# 4 挂载glusterfs
mount -t glusterfs <SERVER>:/<VOLNAME><MOUNTDIR>
#5 创建/启动/停止/删除卷
gluster volume create <NEW-VOLNAME>[stripe <COUNT> \
| replica <COUNT>] \
[transport [tcp | rdma | tcp,rdma]] \
<NEW-BRICK1> <NEW-BRICK2> \
<NEW-BRICK3> <NEW-BRICK4>...
gluster volume start <VOLNAME>
gluster volume stop <VOLNAME>
gluster volume delete <VOLNAME>
注意，删除卷的前提是先停止卷。
# 6 查看卷信息
gluster volume list #列出集群中的所有卷：
gluster volume info [all] #查看集群中的卷信息：
gluster volume status [all] #查看集群中的卷状态：
gluster volume status <VOLNAME> [detail| clients | mem | inode | fd]
# 7 配置卷
gluster volume set <VOLNAME> <OPTION> <PARAMETER>
# 8 扩展卷
gluster volume add-brick <VOLNAME> <NEW-BRICK>
>如果是复制卷，则每次添加的Brick数必须是replica的整数倍。
# 9 收缩卷
## 9.1 先将数据迁移到其它可用的Brick，迁移结束后才将该Brick移除：
gluster volume remove-brick <VOLNAME> <BRICK> start
>在执行了start之后，可以使用status命令查看移除进度：
gluster volume remove-brick <VOLNAME> <BRICK> status
## 9.2不进行数据迁移，直接删除该Brick：
gluster volume remove-brick <VOLNAME> <BRICK> commit
>注意，如果是复制卷或者条带卷，则每次移除的Brick数必须是replica或者stripe的整数倍。
# 10 迁移卷
>使用start命令开始进行迁移
>迁移过程中，可以使用pause命令暂停迁移：
可以使用abort命令终止迁移：
可以使用status命令查看迁移进度：
>在数据迁移结束后，执行commit命令来进行Brick替换：
gluster volume replace-brick <VOLNAME> <BRICK> <NEW-BRICK> start
gluster volume replace-brick <VOLNAME> <BRICK> <NEW-BRICK> pause
gluster volume replace-brick <VOLNAME> <BRICK> <NEW-BRICK> abort
gluster volume replace-brick <VOLNAME> <BRICK> <NEW-BRICK> status
gluster volume replace-brick <VOLNAME> <BRICK> <NEW-BRICK> commit
# 11 重新均衡卷
不迁移数据：
gluster volume rebalance <VOLNAME> lay-outstart
gluster volume rebalance <VOLNAME> start
gluster volume rebalance <VOLNAME> startforce
gluster volume rebalance <VOLNAME> status
gluster volume rebalance <VOLNAME> stop
# 12 磁盘配额
开启/关闭系统配额：
gluster volume quota <VOLNAME> enable | disable
设置目录配额：
gluster volume quota <VOLNAME> limit-usage <DIR> <VALUE>
查看配额：
gluster volume quota <VOLNAME> list [<DIR>]
# 13 地域复制（geo-replication）：
gluster volume geo-replication <MASTER> <SLAVE> start | status | stop
# 14 IO信息查看：
gluster volume profile <VOLNAME> start | info | stop
# 15 Top监控：
>Top命令允许你查看Brick的性能，例如：read,write, file open calls, file read calls, file write calls, directory opencalls, and directory real calls。所有的查看都可以设置top数，默认100。
gluster volume top <VOLNAME> open[brick <BRICK>] [list-cnt <COUNT>]
>其中，open可以替换为read, write, opendir, readdir等。
gluster volume top <VOLNAME> read-perf [bs <BLOCK-SIZE> count <COUNT>] [brick <BRICK>] [list-cnt <COUNT>]
>其中，read-perf可以替换为write-perf等。
