Operating system
T.Lion works on Debian GNU/Linux 9 “Stretch” (x86 or x64). The operating system is installed and configured by the customer.
Note: |
Support for Debian 10 “Buster” is planned in the future versions of T.Lion. In the meanwhile, you can use Long Term Support (LTS) version. |
Refer to Debian Installation Guide for detailed deployment instructions, along with downloadable files. Consider the following guidelines:
- Choose Guided - use entire disk partitioning method and All files in one partition (a single
/
partition withvar
,tmp
, andhome
directories) partitioning scheme.
Alternative partitioning may result in free space issues. - Do not install a desktop environment. It consumes resources and can lead to server instability.
- Linux Kernel Security (SElinux or AppArmor) must be disabled or set to permissive mode.
Important: |
We do not recommend installing any feature updates (except for security patches) or additional software packages on T.Lion servers. |
Packages
- SSH server.
- Standard system utilities.
- BASH version 4 or later is recommended.
Time zone
All T.Lion / T.Brother servers should work in the same time zone and their time must be synchronized. Verify the configuration by executing date
command:
$ date
Mon Jan 12 22:59:24 UTC 2020
To change the time zone, for example from UTC to Pacific time, run:
$ rm /etc/localtime
$ ln -sf /usr/share/zoneinfo/US/Pacific localtime
Configure NTP client for each host to avoid time drift. To immediately sync a server’s time with a time server, run:
$ ntpdate -u [NTP server, e.g europe.pool.ntp.org]
