Use swap files in the installation and running mode of the CF card of IPCopLinux

In the installation and running mode of the CF card of IPCopLinux, use the switch file-Linux Enterprise Application-Linux server application information. For details, refer to the following. In the installation and running mode of the CF card in IPCop Linux, a hard disk file can be set as the swap partition because there is no swap partition. The steps are as follows:

1. Create a swap file in the hard disk:
# Dd if =/dev/zero of =/mnt/hda1/swapfile bs = 1024 count = 655360
655360 + 0 records in
655360 + 0 records out
671088640 bytes (671 MB) copied, 134.763 seconds, 5.0 MB/s
Note: The directory/mnt/hda1 is mounted to the first partition of the hard disk.

2. Create a swap file system in the swap file:
# Mkswap/mnt/hda1/swapfile
Setting up swapspace version 1, size = 671084 kB
No label, UUID = 97524e31-964c-41fe-980b-c193c04ba37b

3. Change the access permission of the swap file:
# Chmod 600/mnt/hda1/swapfile
# Ll/mnt/hda1/swapfile
-Rw ------- 1 root 671088640 swapfile
# File/mnt/hda1/swapfile
Swapfile: Linux/i386 swap file (new style) 1 (4 K pages) size 16383 pages

4. Enable swap file as swap partition:
# Swapon/mnt/hda1/swapfile
# Free
Total used free shared buffers cached
Mem: 1025904 1007408 18496 0 44592 906288
-/+ Buffers/cache: 56528 969376
Swap: 655352 0 655352

5. Enable swap partition when the system starts:
Modify the/etc/rc. d/rc. sysinit file. Some content is as follows:
...
SWAP_FILE =/mnt/hda1/swapfile
If [-e $ SWAP_FILE]; then
Echo "Turning on swap"
Chmod 600 $ SWAP_FILE
Swapon $ SWAP_FILE
