挂载完成,在LAP1上传一个图片,测试文件成功存放在NFS服务上.
此时已经成功了一半了,继续挂载到LAP2
[root@lap2 ~]#yum install nfs-utils.x86_64 -y [root@lap2 ~]#showmount -e 10.0.0.8 Export list for 10.0.0.8: /data/wordpress/wp-content/uploads 10.0.0.* [root@lap2 ~]#vim /etc/fstab 10.0.0.8:/data/wordpress/wp-content/uploads /data/wordpress/wp-content/uploads nfs4 defaults,_netdev 0 0 [root@lap2 ~]#mount -a [root@lap2 ~]#df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 1.9G 0 1.9G 0% /dev tmpfs 1.9G 0 1.9G 0% /dev/shm tmpfs 1.9G 12M 1.9G 1% /run tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup /dev/mapper/centos-root 100G 2.7G 98G 3% / /dev/sda1 1014M 152M 863M 15% /boot /dev/mapper/centos-data 50G 85M 50G 1% /data tmpfs 378M 0 378M 0% /run/user/0 10.0.0.8:/data/wordpress/wp-content/uploads 50G 391M 50G 1% /data/wordpress/wp-content/uploads
测试是否有LAP１上传的图片
