验证码文件保存NFS配置
inspect ip under centOS:
sudo su -
ifconfig
#eth0????? Link encap:Ethernet? HWaddr 00:25:90:00:85:C4
#???????????? inet addr:10.37.30.70? Bcast:10.37.30.127? Mask:255.255.255.192
#serversudo sumkdir -p /home/sharingchown app:app /home/sharingmkdir -p /home/sharing/captchaschown app:app /home/sharing/captchas
vi /etc/exports#add line, 10.37.30.70为客户端IP# /home/sharing 10.37.30.70(rw,sync,no_root_squash)#10.37.30.70 (rw,sync,no_root_squash)? ip和括号间不能有空格?? 对应的客户端touch会出错 touch: cannot touch `/home/sharing/captchas/test5': Read-only file system
修改/etc/exports后必须重启下面的服务/etc/init.d/nfs restart/etc/init.d/portmap restart
#client?sudo sumkdir -p /home/sharingchown app:app /home/sharingmkdir -p /home/sharing/captchaschown app:app /home/sharing/captchas
#要保证app的uid和服务器的app的uid是一致的,su 到app用id命令查看, 不一致要用/usr/sbin/usermod命令改为一致，# eg:/usr/sbin/usermod -u 788 app#修改后退出重新登录，并修改/home/www目录的owner：sudo chown app:app -R /home/www
/etc/init.d/portmap start
#10.18.36.130为服务器IPmount 10.18.36.130:/home/sharing/captchas /home/sharing/captchasmount#看效果，应该有类似：#10.18.36.130:/home/sharing/captchas on /home/sharing/captchas type nfs (rw,addr=10.18.36.130)
vi /etc/fstab#add line:?# 10.18.36.130:/home/sharing/captchas /home/sharing/captchas nfs defaults 0 0
su apptouch /home/sharing/captchas/testll /home/sharing/captchas/
#服务器su appll /home/sharing/captchas/
如果都看到test文件了，说明配置OK
mount: 10.16.254.130:/home/sharing/captchas failed, reason given by server: Permission denied
可能的原因：
1、/etc/hosts里指定了IP--主机名，删之(建议不要擅自修改/etc/hosts)；
2、可能是NFS服务器端/etc/exports设置的权限不对；
3、SELinux的问题：
[root@rhel5 ~]# setsebool -P nfs_export_all_rw on
