Swap for Linux

One, create a new disk as swap

1. If the system itself has swap, stop swap

# swapoff-a

2. Create a new disk partition using FDISK, or the parted tool

3. Format Swap

# MKSWAP/DEV/SDC1

4. Start a new swap

# SWAPON/DEV/SDC1

5. Add to System Auto mount

# Vim/etc/fstab

Uuid=xxxxxx-xxx-xxx-xxx swap swap defaults 0 0

uuid=xxxxxx-xxx-xxx-xxx None swap SW 0 0 (recommended)

Second, use the file as swap

1. Create File Block Size (1G)

# dd If=/dev/zero Of=/tmp/swap bs=1m count=1024

2. Format to swap

# Mkswap/tmp/swap

3. Enable Swap

# Swapon/tmp/swap

4. Add to System Auto mount (IBID.)

# Vim/etc/fstab

/tmp/swap swap ....

/tmp/swap none ....
