NFS服务器安装配置

执行命令：yum install nfs-utils portmap nfs4-acl-tools

编辑设置配置文件：vim /etc/exports

所遇问题：centos6.5

portmap: 未被识别的服务

解决方案:

由于在6系列里面，portmap已经改名了 ，6系列需要使用 service rpcbind start启动

启动rpcbind服务。

启动nfs服务

查看NFS服务器：

更新了/etc/exports后，使用如下命令刷新：

exportfs -r

挂载和卸载nfs文件系统使用：

[root@node4 ~]# clear

[root@node4 ~]# showmount -e 192.168.26.209
