VPS Configuration File
The default VPS configuration file is /hsphere/local/config/vserver/vps.cfg.
WARNING:
1. Do not change location of the configuration file!
2. It is strongly recommended not to make changes to the configuration file manually!
If you need to set parameters to the configuration file,
run /hsphere/shared/scripts/vps-configure.pl
and follow the step-by-step configuration instructions as specified in
VPS Installation Guide
of H-Sphere documentation.
Below are configuration parameters set in the VPS configuration file:

VPS Configuration
Enter the $VPSSCRIPTS directory (Default: /hsphere/shared/scripts) to run the
vps_configure.pl script.
SYNTAX:
./vps-configure.pl [-d|-r|-h]
OPTIONS:
--defaults|-d load default settings
--restore|-r restore settings you made before
--help|-h display this help message
Run vps_configure.pl:
# /hsphere/shared/scripts/vps-configure.pl
Do you really want to reconfigure your VPSs [y/n]?
Kernel: 2.4.21-freevps-1.2-1hugemem
FreeVPS patch build: 1080548030
Base FreeVPS tools package: freevps-tools-1.2-1
H-Sphere VPS scripts package: hsphere-vps-1.2-1
RedHat release: RH73
To perform basic configuration for all virtual servers, follow the VPS Configuration section of the
H-Sphere VPS Installation guide.
VPS Creation
To create new Virtual Private Server, run the vps-post-config.pl script:
./vps-post-config.pl VPS_HOST_NAME
And put in the following parameters to STDIN:
IP=ADDRESS:MASK:HDEV - IP to be assigned to this VPS and allowed on network interface HDEV on your VPS box;
DLIMIT=XXXX - Disk limit in Mb;
MLIMIT=XXXX - Memory Limit in Mb;
PLIMIT=XXXX - Limit on the number of running processes;
FILELIMIT=XXXX - Number of opened files limit;
TCPLIMIT=XXXX - TCP sockets limit;
ROOTPWD=**** - User root password;
CTRL+D - Press Ctrl+d to stop data input.
Example:
Create a VPS with the following configuration:
Hostname: 231.tst
IP address: 192.168.112.231, mask: 255.255.255.0
Disk limit: 3000Mb
Memory limit: 512Mb
Limit on the number of running processes: 1000
Root password: 1
[root@vps scripts]# ./vps-post-config.pl 231.tst
IP=192.168.112.231:255.255.255.0[press Enter]
DLIMIT=3000[press Enter]
MLIMIT=512[press Enter]
PLIMIT=1000[press Enter]
ROOTPWD=1[press Enter]
[press Ctrl+d] (end of data input)
vps-post-config.pl creates the $HSVPSFILES/231.tst/231.tst.in file
(Default: /hsphere/local/config/vserver/cp/231.tst/231.tst.in)
with the input parameters,
and registers VPS in the list of known vservers:
$VPSCONFIGS/vps.list (Default: /hsphere/local/config/vserver/vps.list)
Check the list of VPSs:
[root@vps scripts]# cat /hsphere/local/config/vserver/vps.list
You would get something like this:
DELETE=""
VSERVERS="3:231.tst"
Format:
DELETE="HOSTNAME1 HOSTNAME2 HOSTNAME3" - the list of VPSs scheduled for deletion,
separated with whitespaces;
VSERVERS="CONTEXT_ID1:HOSTNAME1 CONTEXT_ID2:HOSTNAME2" - the list of known VPSs,
separated with whitespaces;
CONTEXT_ID is a virtual server ID
VPS Cron Scripts
These are VPS scripts scheduled in cron on the host server:
*/5 * * * * /hsphere/shared/scripts/cron/vps-cron.pl >/dev/null 2>&1
59 */1 * * * /hsphere/shared/scripts/cron/vps-cron-traf.pl >/dev/null 2>&1
*/4 * * * * /hsphere/shared/scripts/cron/vps-cron-delete.pl >/dev/null 2>&1
00 5 * * * /hsphere/shared/scripts/cron/vps-cron-fix.pl >/dev/null 2>&1
1. vps-cron.pl
The $VPSSCRIPTS/cron/vps-cron.pl script
(Default: /hsphere/shared/scripts/cron/vps-cron.pl)
runs every 5 minutes.
It is used to install and configure new Virtual Private Servers.
The script works as follows:
- It checks the list of known vservers and
takes each VPS and processes requested tasks
from the $HSVPSFILES/VPS_NAME/VPS_NAME.in file (Default: .../cp/VPS_NAME/VPS_NAME.in).
- If the requested task is successfully done, it creates a note in
the $HSVPSFILES/VPS_NAME/VPS_NAME.out file (Default: .../cp/VPS_NAME/VPS_NAME.out)
- If all of the requested tasks are done, it creates the DONE file:
$HSVPSFILES/VPS_NAME/VPS_NAME.done (Default: .../cp/VPS_NAME/VPS_NAME.done),
and deletes the request file:
$HSVPSFILES/VPS_NAME/VPS_NAME.in (Default: .../cp/VPS_NAME/VPS_NAME.in).
- It creates the FLAG file:
$STATCRONPID (Default: /var/log/hsphere/vps_cron.pid)
with its own PID, to prevent executing another copy of it.
- It creates all configuration files required for VPSs:
$VPSCONFIGS/VPS_NAME.conf (Default: /hsphere/local/config/vserver/VPS_NAME.conf)
$VPSCONFIGS/VPS_NAME.sh (Default: /hsphere/local/config/vserver/VPS_NAME.sh)
- It installs basic Linux RH7.3 packages and additional packages if configured,
creates services, set limits, assigns IPs, and finaly, starts VPS.
2. vps-delete.pl
SYNTAX:
./vps-delete.pl VPS_HOST_NAME
- It removes existing VPS [VPS_HOST_NAME], all its configuration files,
removes [VPS_HOST_NAME] from the list of known VPS.
- If [VPS_HOST_NAME] is being created by cron at the moment, [vps-delete.pl]
posts deletion request for VPS (sets the DELETE parameter in the vps.list file)
- All deletion requests are processed by vps-cron-delete.pl cron every 4 minutes.
3. cron-traf.pl
Processes VPS network traffic statistics.
Creates files with VPS daily traffic statistics:
/hsphere/local/var/statistic/DD.MM.YYYY.vps.txt
4. cron-fix.pl
Fixes Disk Usage value for each of known VPS servers.
