## SYNTAX ###
##
## Lignes of this script can be 3 types :
## - beginning with  "###" when line is doc title
## - beginning with  "##" when line is documentation
## - beginning with  "#" when line is a commented line for testing
## - beginning without any "#" when line is interpreted


### Installation of a TANGO server
## Based on a Debian 8 / 9
## script installation duration : ~ 9 to 15 minutes depending on the options


### Instructions to launch the script:
##
## 1 install OS, with an existing ${ARCHIVING_DIR} directory for archiving
##   installation, and on a distinct partition to avoid disk crashing 
##   if temporary files are not deleted
## 2 check that /etc/sudoers contains the main user, if not:
##   "su"
##   "apt-get install sudo"
##   "usermod -aG sudo [MAINUSER]"
##   then completely close session and open it again
## 3 for installing on virtual machine: check that 
##   /etc/apt/sources.list contains contrib
## 4 get the script ("sudo apt-get install git" &
##   "git clone https://gitlab.in2p3.fr/CCThomX/installation.git")
## 5 check if setxkbmap is well configured if necessary
## 6 configure the INSTALLATION PARAMETERS in the script including 
##   ARCHIVING_DIR
## 7 launch the script with tangoserver name as parameter
##   ("cd ThomX-Config ; sudo script-install.sh [TANGOSERVER]")
## 8 on distant host, install xauth package (sudo apt-get install xauth)
## 9 test:
##   * DOWNLOAD_ONLY: launching the script with the same configuration
##     should work offline 
##   * VIRTUALBOX: increasing the size of virtualbox window should 
##     increase the size of virtual screen
##   * DATABASE: connection to MariaDB (Debian 9) or MySQL (Debian 8) 
##     should work
##     `mysql -h localhost -u tango -p` followed by `USE tango` and then `SHOW tables;` 
##     should print following tables:

##         `Exported: true`  with an accessible `port`
##       - if former step is not checked, launch on the server TangoTest 
##         device server with `/usr/lib/tango/TangoTest test` and check that 
##         terminal displays `Ready to accept request` 
##       - ` cd IHM/RFCanon and launch `./RF_Canon.py`, a window should appear 
##         while data changes every second
##     + configure SSH with a private key giving access to DS-LAL repo and get 
##       the repo `git clone git@gitlab.in2p3.fr:CCThomX/DS-LAL.git`
##       Then build a DS.
##   * ARCHIVING: to complete by JCM
##
## If any issue occurs, you can check installation parameters are well 
## spelled with command debconf-get-selections from package debconf-utils.
