04. 搭建Qt网络文件系统

4.1 解压qt网络文件系统

[root@itcast Qt]# pwd/home/tools/Qt[root@itcast Qt]# lsramdisk-u.img  rootfs_qtopia_qt4-20141213.tar.gz[root@itcast Qt]# tar -xzvf rootfs_qtopia_qt4-20141213.tar.gz

4.2 移动目录

[root@itcast Qt]# mv rootfs_qtopia_qt4  /[root@itcast Qt]# cd /[root@itcast /]# mv rootfs_qtopia_qt4/ qtrootfs[root@itcast /]# lsbin   cgroup  etc   lib    lost+found  misc  net  proc      root  selinux  sys  usrboot  dev     home  lib64  media       mnt   opt  qtrootfs  sbin  srv      tmp  var[root@itcast /]#

4.3 设置nfs共享

[root@itcast /]# vim /etc/exports #最后添加一下内容/qtrootfs *(rw,sync,no_root_squash)

4.4 启动nfs服务

[root@itcast /]# iptables -F [root@itcast /]# setenforce  0[root@itcast /]# /etc/init.d/rpcbind restart停止 rpcbind：                                             [确定]正在启动 rpcbind：                                         [确定][root@itcast /]# /etc/init.d/nfs restart关闭 NFS 守护进程：                                        [失败]关闭 NFS mountd：                                          [失败]关闭 NFS quotas：                                          [失败]Shutting down RPC idmapd:                                  [失败]启动 NFS 服务：                                            [确定]关掉 NFS 配额：                                            [确定]启动 NFS mountd：                                          [确定]启动 NFS 守护进程：                                        [确定]正在启动 RPC idmapd：                                      [确定][root@itcast /]#

4.5 验证共享目录

[root@itcast Android]# showmount  -e 172.16.0.53Export list for 172.16.0.53:/qtrootfs *

4.6 设置启动参数

DengJin #set bootargs root=/dev/nfs nfsroot=172.16.0.88:/qtrootfs ip=172.16.0.77  console=ttySAC0,115200 lcd=S70 ctp=2DengJin #save

4.7 环境变量如下
