CentOS 下 修改ramdisk 大小

如果已经 配置好了 ramdisk
敲入下面的命令
mkdir /tmp/ramdisk && mount -v -t tmpfs -o size =512M none /temp/ramdisk


官网原文如下

mkdir /mnt/ram && mount -v -t tmpfs -o size=64M none /mnt/ram

If you want to use the RAM disk permanently you could use an entry in
/etc/fstab:
none  /mnt/ram  tmpfs  size=64M  0 0

Besides, there is already a RAM disk available: /dev/shm
