Fedora 17 x64如何配置nfs服务 测试环境: [root@tp system]# uname -a Linux tp 3.3.4-5.fc17.x86_64 #1 SMP Mon May 7 17:29:34 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux 配置nfs exports: vim /etc/exports /run/media/k/Elements/unzip/ora11gR2forLinux64 192.168.221.0/24(rw,sync,no_root_squash) www.2cto.com 激活exports,可直接用exportfs刷新或者重启服务: 1. exportfs刷新: [root@tp system]# exportfs -avf exporting 192.168.221.0/24:/run/media/k/Elements/unzip/ora11gR2forLinux64 2. 重启服务: [root@tp system]# systemctl restart nfs-server.service 查看本机共享出的nfs文件夹: [root@tp system]# showmount -e Export list for tp: /run/media/k/Elements/unzip/ora11gR2forLinux64 192.168.221.0/24 www.2cto.com 换台机器挂载nfs文件夹: [root@rac1 ~]# mount -t nfs 192.168.221.1:/run/media/k/Elements/unzip/ora11gR2forLinux64 /mnt [root@rac1 ~]# df -h 文件系统 容量 已用 可用 已用% 挂载点 /dev/mapper/VolGroup00-LogVol00 188G 2.7G 176G 2% / /dev/sda1 99M 23M 71M 25% /boot tmpfs 2.0G 0 2.0G 0% /dev/shm /dev/sr0 3.6G 3.6G 0 100% /media 192.168.221.1:/run/media/k/Elements/unzip/ora11gR2forLinux64 932G 806G 127G 87% /mnt [root@rac1 ~]# www.2cto.com 注意问题: 1. 检查配置没有问题后,仍无法发现nfs共享,可以先临时关闭防火墙(systemctl stop iptables.service)和SELINUX(setenforce 0),再试试看。
2. 客户机上能发现nfs共享,并且可以成功mount,但是没有权限列出mount后的目录,需要加no_root_squash到nfs exports选项里,这样客户机能以root权限来查看nfs共享文件夹。 man exports root_squash Map requests from uid/gid 0 to the anonymous uid/gid. Note that this does not apply to any other uids or gids that might be equally sensitive, such as user bin or group staff. no_root_squash Turn off root squashing. This option is mainly useful for disk less clients. REF: 1. Fedora 17 - NFS Server : Server World http://www.server-world.info/en/note?os=Fedora_17&p=nfs
