In most Linux releases of Linux memory virtual disks, memory disks use the/dev/shm path by default. the default size of the file system type tmpfs is the actual memory size, this is in line with the actual operation habits. The operation path is the operation on the memory. Www.2cto.com we can reset the size of this memory disk, or create a new memory disk to accelerate some special applications, such as squid buffering and dns buffering files. Reset the memory disk size: for example, mount-o remount, size = 3G/dev/shm. Note that the size can be measured in MB \ k \ G to create a memory disk. for example: mkdir/usr/local/squid/var/cachemount-t tmpfs-o size = 3G, mode = 0755 tmpfs/usr/local/squid/var/cache note: After you reset the memory disk, you must write it to the fstab file to enable it next time. generally, linux is in/etc/fstab.
