The Gandi agent and server configuration files
The role of the Gandi agent
In expert mode, the Gandi configuration agent is tasked with receiving information about server parameters, number of cores, RAM, new disk size, disks to be attached or detached, and so on.
gandi-hosting-vm2
package, which may need to be updated in order to take advantage of the latest improvements.
To do this, use the command 'aptitude install gandi-hosting-vm2'.
Gandi config files
Several files and directories are available to you for the purposes of adapting your expert server to your needs.
/etc/gandi
This directory contains our configuration scripts.
/etc/default/gandi
In this file you can adjust the following parameters:
- choose between short hostname or FQDN
- create/activate swap at boot
- change the MOTD for SSH connections
- change the time zone
- activate/deactivate specific Gandi system options (
sysctl
) - add/remove Gandi SSH keys to grant or revoke our access
- change SSH options (
Compression
,PermitRootLogin
,EmptyPasswords
) - update (or don't update)
/etc/resolv.conf
via DHCP - automatically configure the emergency console
- activate/deactivate PAM changes for root access
- activate/deactivate automatic hostname configuration
- activate/deactivate automatic DNS server configuration
- change data disk mount options and default mount locations
/etc/sysconfig/gandi
/etc/udev/rules.d/86-gandi.rules & /etc/fstab
You have two ways of mounting disks on your virtual server:
udev
(default)
By default, udev
takes care of automatically mounting data disks on /srv/
with the name of the disk. For example, a data disk named d_data
would be mounted at /srv/d_data/
.
fstab
(udev deactivated)
If you want to specify your own mount points, you must deactivate the udev
rules related to the disks in the file /etc/udev/rules.d/86-gandi.rules
(the VPS will need to be rebooted in order for changes to this file to take effect).

/etc/init.d/gandi-mount & /etc/init.d/gandi-kernel
gandi-mount
This script allows disks attached to the server and present in /proc/partitions
to be mounted on /srv/
.
gandi-kernel
This script automates the installation of kernel modules.
