NetDRMS Installation

Preliminary note

In the following sections, when there is a command line :
#_ means that command is executed into _root user
$_ means that command is executed into _production user

Requirements

Configuring production environment

Adding user production (en root)

# adduser production
# addgroup ias
# adduser production ias

Configure /home/production/.profile

Adding environment variables

#Modif Herve.B Pablo.A 12/05/2016

PATH="/usr/local/netdrms_current/bin/linux_x86_64:$PATH" 
PATH="/usr/local/netdrms_current/scripts:$PATH" 
PATH="/usr/local/jmd/bin:$PATH" 
PATH="/usr/local/jmd/scripts:$PATH" 
#The following is not needed as installed with 'apt-get install' 
#PATH="/usr/local/pgsql/bin:$PATH" 
PATH="/usr/local/netdrms-tools/scripts:$PATH" 
#2014-12-17 Avec Herve et Pablo on pense que la ligne suivante est intutile as it is f.. install in /usr/local/lib
PATH="/usr/local/cfitsio:$PATH" 
#Done

DERBY_HOME=/usr/local/jmd/databases/derby/derbyBD
export DERBY_HOME

export CVSROOT=:pserver:anonymous@solarch.tuc.noao.edu:2401/vtarc1/vso/cvsroot

Configure /varl/lib/postgres/.profile

Add to $PATH so postgres can exeute command like initdb

#Modif Herve.B Pablo.A 19/05/2016
PATH="/usr/lib/postgresql/9.4/bin:$PATH"

Setting privileges for SUMS_MANAGER

Please modify file /etc/sudoers so user 'production' will be able to execute 'sum_chown' that we will locate in the dir : /usr/local/bin . See below
Add to /etc/sudoers the following line :
production host=NOPASSWD:/usr/local/bin/sum_chmown

Set passwords file for db postgres

Please create file .pgpass with the following information for user 'production" so he will be able to connect without password as 'production' or 'postgres' to 2 db that we will create later ias_sdo and ias_sdo_sums.

.pgpass content :

    #hostname:5432:ias_sdo:production: 
    #hostname:5434:ias_sdo_sums:production: 
    #hostname:5432:ias_sdo:postgres: 
    #hostname:5434:ias_sdo_sums:postgres

where #hostname is the name of your server

WARNING : change hostname when migrate sdo-new to sdo

Install missing libraries

• libreadline-dev (but already installed with postgresql)
• libssl-dev
• libpam0g-dev
• libperl-dev

NB : Already done in Debian 8.4 Jessy

# apt-get install $library_name

where
$library_name is the name of library

Then to update path on libraries, please type :

# ldconfig

Reconfigure locale

# dpkg-reconfigure locales

select fr_FR.UTF8 UTF8 and unselect en_US.UTF-8

localedef -i en_US -f UTF-8 en_US.UTF-8

(see here : [[http://www.thomas-krenn.com/en/wiki/Perl_warning_Setting_locale_failed_in_Debian]])

apt-get install python3-psycopg2

apt-get install python3-psycopg2

Add python3-pip for modules within python3

apt-get install python3-pip

pip3 install pySmartDL

Both python2.7 and 3.4 versions are installed on the system.
By default, the python2.7 is used.
In order to change in 3.4 by default, type :

update-alternatives --config python

Installation of sdo_scripts

Install monitoring scripts for sdo

rsync -av scripts production@sdo-new:/home/production/netdrms-tools/

NetDRMS databases

into /var/lib/postgresql (hard mount point separated, 7 disks 15000 tr/min in raid5 in order to distribute read and write)

# cd /var/lib/postgresql
# mkdir data  data_sums data_monitor
# chown -R postgres:postgres *

Initialize 3 servers data, data_sums, data_monitor

Into postgres

# su - postgres

$ initdb --locale=C -D data -A md5 -W
(no password)

Success. You can now start the database server using:

    postgres -D data
or
    pg_ctl -D data -l logfile start

$ initdb --locale=C -D data_sums -A md5 -W
(no password)

Success. You can now start the database server using:

    postgres -D data_sums
or
    pg_ctl -D data_sums -l logfile start

$ initdb --locale=C -D data_monitor -A md5 -W
(no password)

Success. You can now start the database server using:

    postgres -D data_monitor
or
    pg_ctl -D data_monitor -l logfile start

Edition des fichiers postgresql.conf pour configurer les bons ports d'écoute :
listen_addresses = '*'
data -> port 5432
data_sums -> port 5434
data_monitor -> port 5436

Edit files data*/pg_hba.conf : replace 'md5' by 'trust'

System tuning

Current configuration :

# sysctl -a

In the following file :

# vi /etc/sysctl.conf

we change some values (default values are commented with '#')

(resources links here)

# Semaphore is a object that is used to control utilization of a particular process.
# kernel.sem = SEMMSL SEMMNS SEMOPM SEMMNI
# SEMMSL        maximum number of semaphores per array  (min 128)

SSH-HPN install

Intallation de openssh 7.2p2 car le dernier patch hpn dispo est 7.2hpn14.V10

web site for open ssh : http://ftp2.fr.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-7.2p2.tar.gz
patch hpn : https://sourceforge.net/projects/hpnssh/files/HPN-SSH%2014v10%207.2p2/openssh-7_2_P2-hpn-14.10.diff

In the dir /home/production/sources into 'root'

# tar -xzvf openssh-7.2p2.tar.gz
# cd openssh-7.2p2/
# cat ../openssh-7_2_P2-hpn-14.10.diff |patch -p1
# ./configure --prefix=/usr/local/hpn-ssh --with-pam --with-md5-passwords --without-zlib-version-check --with-tcp-wrappers
# make
# make install

Depuis sdo :

# cd /usr/local/hpn-ssh/etc/
# rsync -av *key* production@sdo-new:/home/production/

Following the link : http://vso.stanford.edu/netdrms/rmtsums.html

$ cd /home/production/
$ ssh-agent -c > ~/.ssh-agent_rs
$ source ~/.ssh-agent_rs
$ ssh-add ~/.ssh/id_rsa

Sur sdo-new :

# mv /home/production/*key* /usr/local/hpn-ssh/etc/

We have to configure the port number to 55000

# vi ssh_config

and add :

#Port 22
Port 55000

We configure also the server hpn (even we don't use it yet)

# vi sshd_config

and add :

#Port 22
Port 55000

#PidFile /var/run/sshd.pid
PidFile /var/run/sshd.55000.pid

# allow the use of the none cipher
#NoneEnabled no
NoneEnabled yes

In order to force the use of SSH-hpn by JMD :

$ vi /usr/local/jmd/cfg/JMD.cfg

and replace the path of scp binary :

SCPCommand=/usr/local/hpn-ssh/bin/scp -o NoneSwitch=yes -o NoneEnabled=yes

Private key Public key generation

JSOC need your public key to directly connect to your netdrms server. In order to generate your RSA public/private key pair :

$ ssh-keygen -t rsa

Not necessary in our case cause we recover the ssh keys of the current server 'sdo'.

However, we have to retrieve the private key of production account on sdo-new

From sdo :

rsync -av id_rsa production@sdo-new:/home/production/.ssh/

NetDRMS replication

# cd base/drms/replication/etc
# scp production@sdo:/usr/local/netdrms/install-config-files/ias.subscribe_list.cfg  .
# scp production@sdo:/usr/local/netdrms/install-config-files/ias.repclient.cfg  .
WRONG !!!!!
To be done cp repclient.template.cfg into ias.subscribe_list.cfg because new field in config file can't appear 
Correct that step in NetDrms doc 
The existing ias.repclient.cfg can be used tough to fill params

Create tmp dir in netdrms working directory (/usr/local/netdrms_current)

# mkdir tmp

Modification du fichir config.local pour la souscription au jsoc

# NetDRMS users can request subdirectories from the Stanford proj directories 
# (e.g., JSOC/proj/util). These users will need to contact Stanford and obtain
# the source subdirectories desired. They will then place these subdirectories
# in the JSOC/proj directory of their NetDRMS release. To properly build 
# targets in these subdirectories, using the JSOC make system, the user needs
# to add entries to this configuration file - one entry for each subdirectory
# that contains source code to be compiled. Each entry is a space-separated pair
# of strings: the string "PROJDIR" followed by a subdirectory (of the proj 
# directory).  For example:
#
# PROJDIR     util/apps
# PROJDIR     util/libs
# 
# NOTE: It is not sufficient to list only a parent directory, like util. Source code
# in child directories will not automatically be compiled.
