h1. NetDRMS Installation

h2. Requirements

h3. Configuring production environment

Adding user production (en root)

<pre>

# adduser production

# addgroup ias

# adduser production ias

</pre>

h3. Configure /home/production/.profile

Adding environment variables

<pre>

#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

</pre>

h3. Configure /varl/lib/postgres/.profile

Add to $PATH so postgres can exeute command like initdb

<pre>

#Modif Herve.B Pablo.A 19/05/2016

PATH="/usr/lib/postgresql/9.4/bin:$PATH"

</pre>

h3. 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

h3. 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 :

<pre>

	#hostname:5432:ias_sdo:production: 

	#hostname:5434:ias_sdo_sums:production: 

	#hostname:5432:ias_sdo:postgres: 

	#hostname:5434:ias_sdo_sums:postgres

</pre>

where #hostname is the name of your server

%{color:red}WARNING : change hostname when migrate sdo-new to sdo%

h3. Install missing libraries 

• libreadline-dev (but already installed with postgresql)

• libssl-dev

</pre>

h2. System tuning

Current configuration :

<pre>

# sysctl -a

</pre>

In the following file :

<pre>

# vi /etc/sysctl.conf

</pre>

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

(resources links [[Links|here]])

<pre>

# 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)

Then we run the following command to make our change take effect:

<pre>

# sysctl -p

h3. Modification du fichier /usr/local/netdrms_current/configure (Not Applied in NetDrms_8.10)

<pre>

# The system configuration for configure script

set PERLBIN = "/usr/bin/perl"

set PYBIN = "/usr/bin/python"

</pre>

h3. Compilation problem due to uncorrect variable types

Art (art.amezcua@stanford.edu) purpose us a workaround and send us 2 files with correct declaration :

SUMLIB_RmDo.pgc (diff with original file : [[diff_SUMLIB_RmDo.pgc]])

SUMLIB_RmDoX.pgc (diff with original file : [[diff_SUMLIB_RmDoX.pgc]])

Dans le répertoire base/sums/libs/pg renommer les anciens en *.orig et placer les nouveau fichiers SUMLIB_RmDo.pgc et SUMLIB_RmDoX.pgc

<pre>

# wget http://jsoc.stanford.edu/~arta/SUMLIB_RmDo.pgc

# wget http://jsoc.stanford.edu/~arta/SUMLIB_RmDoX.pgc

</pre>

h3. Modification du fichier /usr/local/netdrms_current/build/jsoc_machine.csh

ligne 28 :

<pre>

  case "x86_64":

      echo linux_x86_64

      breaksw

</pre>

Overwriting the existing files in the right place (base/sums/libs/pg) & modif in jsoc_machine.csh 

=> the command 'make' works well.

But there is still problem with 'make sums'

h3. Workaround to solve make sums problem

Modify [[sum_rpc.h]] in order to match the type of some variables

h3. Copier /usr/local/netdrms_2.4_release/base/drms/apps/serverdefs.h dans /usr/local/netdrms_current/base/drms/apps (not applied in NetDrms_8.10)

NB : lib64 does not exist on debian 8. so ln -s /usr/lib lib64

h2. make sums KO  (Not applied in NetDrms_8.10)

Solution found : Take old lib libcrypto instead libssl

dans le fichier base/sums/apps/Rules.mk ligne 51 

replace -lssl by -lcrypto LD flag

h2. NetDRMS replication

<pre>

# 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 

</pre>

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

<pre>

# mkdir tmp

</pre>

h2. Private key Public key generation 

<pre>

ssh-keygen -t rsa

</pre>

Not necessary cause we recover the ssh keys of the current server.

However, we have to retrieve the private key of production account on sdo3

From sdo :

<pre>

rsync -av id_rsa production@sdo3:/home/production/.ssh/

</pre>

h2. Node definition

</pre>

h2. show_series and delete_series binaries

Remark : these 2 sources are not compiled during installation

Issue : in netdrms_current 8.10 , do :

$ make delete_series

$ make show_series

h2. SSH-HPN install

h3. Modification du fichir config.local pour la souscription au jsoc

<pre>

# 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.
