linux nfs文件挂载模拟云存储

背景

产品上线前兼容性测试，云存储未到位；

系统：SUSE Linux Enterprise Server 11 SP1

解决方法

其中一个服务器A开放nfs服务，模拟云存储，其它服务器挂载A的目录，模拟实现同一存储

实施

前提，需要有portmap和nfs-utils

rmc01:/root # rpm -qa |grep portmapportmap-5beta-749.15rmc01:/root # rpm -qa |grep nfs-utilsnfs-utils-1.0.7-36.29

发现已安装，启动并检查状态

rmc01:/etc/init.d # ./nfsserver startStarting kernel based NFS server                                      donermc01:/etc/init.d # service nfsserver statusChecking for kernel based NFS server:                                 runningrmc01:/etc/init.d # service portmap  statusChecking for RPC portmap daemon:                                      running

需要注意，在SUSE上，服务名为nfsserver，不是nfs

rmc01:/etc/init.d # service nfs statusChecking for mounted nfs shares (from /etc/fstab):                    unus

编辑/etc/exports时注意加上sync选项，如下：

/home/xia/share 10.*.*.*(rw,no_root_squash,<strong>sync</strong>)

不然会有警告

rmc01:/home/xia/share # /etc/init.d/nfsserver restartShutting down kernel based NFS server                                 doneStarting kernel based NFS serverexportfs: /etc/exports [6]: No 'sync' or 'async' option specified for export "10.*.*.*:/home/xia/share".  Assuming default behaviour ('sync').  NOTE: this default has changed from previous versions                                                                      done

然后就是重启nfsserver服务和挂载
