VPS template is a predefined set of RPMs to install a certain service, tool or application.
Templates are installed to VPS upon its creation or to a live VPS.
Basically, template is a structured file with the list of RPM packages, including their names,
full version and platform architecture.
All VPS templates are located in the $VPSCONFIGS/$LINUXCODE directory. Default location:
Red Hat Linux release 7.3: /hsphere/local/config/vserver/RH73
Red Hat EL 3, CentOS 3.x, White Box EL 3: /hsphere/local/config/vserver/RHES3
VPS templates have the following filename format:
where <template_name> may contain any characters possible in Unix file names,
except '_' and '.'.
RPM files listed in the templates must be located either in your $LINUXRPMS directory (this
location can be configured by runnung the vps-configure.pl script), or in the
H-Sphere packages directory $HSINSTALLPKG/$LINUXCODE:
Red Hat Linux 7.3: /hsphere/install/pkg/RH73
Red Hat EL 3, CentOS 3.x, White Box EL 3: /hsphere/install/pkg/RHES3
VPS Template Creation and Modification
RPM files listed in template file must satisfy all dependences during their installation.
To configure, modify, create new templates, run the vps-configure.pl script.
You will see the following prompt:
Application Templates available to install:
1 - [ ] dns-server
2 - [ ] development-tools
3 - [ ] ftp-server
4 - [ ] mail-server
5 - [ ] mysql-server
6 - [ ] news-server
7 - [ ] perl-full
8 - [ ] pgsql-server
9 - [ ] samba-server
10 - [ ] system-tools
11 - [ ] web-server
[ a ] - add template
[ d ] - delete template
[ c ] - change template installation order
(must satisfy package dependences during installation)
[ n ] - new template
[ m ] - modify template
[ s ] - save and exit
[ e ] - exit without saving
Enter the number of a template to be turned on/off, or choose any of the options:
- [ a ] - add template - select this option to add an existing template to be available for VPS
- [ d ] - delete template - select this option to delete an existing template from the list of
available templates for VPS installation.
- [ n ] - new template - select this option to create your own custom template.
Here you will be promted for the template name and the names of RPM packages to be
included into the template. Package names listed in the template must be each in new line.
When you finish, press Ctrl+D.
- [ m ] - modify template - use this option to modify the list of packages
included to the template.
Then, you save the list and exit ([ s ]), or exit without save ([ e ]).
