服务器使用Centos 64位 | PHP5.4 | Nginx环境。网站以及所有的相关程序配置文件均放在 /data/ 下。网站可以正常访问。后新购买了10G的数据盘，想将原来系统盘里的网站数据放在新数据盘下，但迁移后无法访问。不知道问题出在什么地方。
mv /data /data.bak 先把原文件夹更名为 data.bak
然后运行这样一个脚本创建／data 目录，并把数据盘挂载到／datacount=0（这个脚本我也不是太明白，挂载一个盘到一个新创建的目录为什么这么复杂）
tmp1=/tmp/.tmp1
tmp2=/tmp/.tmp2
>$tmp1
>$tmp2
fstab_file=/etc/fstab
#check lock file ,one time only let the script run one time
LOCKfile=/tmp/.$(basename $0)

cp -R /data.bak/* /data 最后把原来备份的网站数据和配置文件拷贝到/data下。 |
