ClusterStorage-4-配置客户端实验

0.实验前的环境检查与配置

[student@workstation ~]$ lab clients-lab setup
 

1.配置防火墙

firewall-cmd --add-service=rpc-bind --add-service=nfs放行服务。 firewall-cmd --runtime-to-permanent永久放行。

[root@servera ~]# firewall-cmd --add-service=rpc-bind --add-service=nfs
Warning: ALREADY_ENABLED
[root@servera ~]# firewall-cmd --runtime-to-permanent
success
 

2.配置选项设置

gluster volume set wallace nfs.disable on禁用nfs的功能开启。 gluster volume set wallace auth.allow 172.25.250.254允许指定地址访问。gluster volume stop wallace关闭存储卷。gluster volume start wallace启动存储卷。

[root@servera ~]# gluster volume set wallace nfs.disable on
volume set: success
[root@servera ~]# gluster volume set wallace auth.allow 172.25.250.254
volume set: success
[root@servera ~]# gluster volume stop wallace
Stopping volume will make its data inaccessible. Do you want to continue? (y/n) y
volume stop: wallace: success
[root@servera ~]# gluster volume start wallace
volume start: wallace: success
 

3.配置选项设置

gluster volume set gromit nfs.disable off关闭禁用nfs的功能。gluster volume set gromit nfs.rpc-auth-allow '172.25.250.*'允许对指定网络的文件输出设置规则。gluster volume set gromit nfs.rpc-auth-reject 172.25.250.254拒绝指定地址设置规则。

[root@servera ~]# gluster volume set gromit nfs.disable off
volume set: success
[root@servera ~]# gluster volume set gromit nfs.rpc-auth-allow '172.25.250.*'
volume set: success
[root@servera ~]# gluster volume set gromit nfs.rpc-auth-reject 172.25.250.254
volume set: success
 

4.配置挂载

mkdir /mnt/wallace创建挂载目录。echo "servera:/wallace /mnt/wallace glusterfs defaults 0 0" >> /etc/fstab将挂载信息写入配置文件。tail -1 /etc/fstab确认配置文件的写入内容。mount /mnt/wallace进行挂载。mount | grep wallace确认挂载。 df -Th | grep wallace查看文件系统。

[root@workstation ~]# mkdir /mnt/wallace
[root@workstation ~]# echo "servera:/wallace /mnt/wallace glusterfs defaults 0 0" >> /etc/fstab
[root@workstation ~]# tail -1 /etc/fstab
servera:/wallace /mnt/wallace glusterfs defaults 0 0
[root@workstation ~]# mount /mnt/wallace
[root@workstation ~]# mount | grep wallace
servera:/wallace on /mnt/wallace type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072)
[root@workstation ~]# df -Th | grep wallace
servera:/wallace            fuse.glusterfs  4.0G   66M  4.0G   2% /mnt/wallace
 

5.配置挂载

mkdir /mnt/gromit创建挂载目录。echo "servera:/gromit /mnt/gromit nfs rw 0 0" >> /etc/fstab将挂载信息写入配置文件。tail -1 /etc/fstab确认配置文件的写入内容。mount /mnt/gromit进行挂载。mount | grep gromit确认挂载。df -Th | grep gromit查看文件系统。

[root@servere ~]# mkdir /mnt/gromit
[root@servere ~]# echo "servera:/gromit /mnt/gromit nfs rw 0 0" >> /etc/fstab
[root@servere ~]# tail -1 /etc/fstab
servera:/gromit /mnt/gromit nfs rw 0 0
[root@servere ~]# mount /mnt/gromit
[root@servere ~]# mount | grep gromit
servera:/gromit on /mnt/gromit type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=172.25.250.10,mountvers=3,mountport=38465,mountproto=tcp,local_lock=none,addr=172.25.250.10)
[root@servere ~]# df -Th | grep gromit
servera:/gromit nfs       4.0G   65M  4.0G   2% /mnt/gromit
 

6.任务测评

lab clients-lab grade进行任务测评。主要包括：防火墙的配置，挂载目录，挂载配置，选项设置，挂载与取消挂载，存储卷可用等。
