linux系统挂载数据盘到VPS自定义目录
linux系统挂载数据盘到VPS自定义目录
如果挂载数据盘做网站的目录,最好先备份好站点文件及数据，然后去挂载,不然挂载到原来有数据的目录会丢失,查看数据盘名称。其中/dev/vdb为数据盘。
fdisk -l
可以看到10G是系统盘,新加(vdb)的250G是数据盘,没有挂载的,根据你自己的数据盘名字变化,,现在来操作一下,看截图:
fdisk /dev/vdb1
因为我之前已经操作过一次了,看图来操作就好了,然后再次fdisk -l。
分区好了就可以格式化了.
mkfs.ext3 /dev/vdb1
如果有网站目录就直接设置,没有就创建/home/wwwroot,然后加到启动项挂载.
mkdir /home/wwwroot
echo '/dev/vdb1 /home/wwwroot ext3 defaults 0 0' >> /etc/fstab
mount -a
end,最后分享个自动分区脚本,root下操作
bash auto_fdisk.sh
