h1. NetDRMS 8.12 Installation

h2. Preliminary note

In the following sections, when there is a command line :

<pre>#</pre>means that command is executed into _root_ user

<pre>$</pre>means that command is executed into _production_ user

h2. Environment

Server : DELL PowerEdge R730

RAM : 64.00GB

CPU : 32 CPUs Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz

Storage Configuration :

* 264 GB mounted in / (2 X 278.88 GB SAS 12G disks in RAID1)

* 1,7 TB mounted in /var/lib/postgresql (7 X 278.88 GB SAS 12G disks in RAID5 configuration)

* 1 global spare for both RAID

* DDP storage mounted in /SUM*

Guest OS : Debian 8.4

Kernel : Linux sdo-new 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt25-1 (2016-03-06) x86_64 GNU/Linux

h2. Requirements

h3. Configuring production environment

Adding user production

<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 

* libpam0g-dev 

* libperl-dev 

* libnet-ssh-perl

<pre>

# ldconfig

</pre>

h3. Reconfigure locale

<pre>

# dpkg-reconfigure locales

</pre>

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

(no password)

Success. You can now start the database server using:

    postgres -D data_monitor

or

    pg_ctl -D data_monitor -l logfile start

</pre>

Edition des fichiers postgresql.conf pour configurer les bons ports d'écoute :

listen_addresses = '*'

data -> port 5432

data_sums -> port 5434

h3. Tunning postgres 

In file postgres.conf ( according to https://www.qwant.com/?q=Tunning+postgres+server+9.4+&client=firefox  )

h3. Start the 3 databases :

<pre>

# su - postgres

$ cd /var/lib/postgresql

$ pg_ctl -D data  start

$ pg_ctl -D data_sums start

$ pg_ctl -D data_monitor start

</pre>

h3. Create the 3 databases :

Into user 'postgres'

* createdb --locale C -E LATIN1 -T template0 ias_sdo

* createdb --locale C -E LATIN1 -T template0 -p 5434 ias_sdo_sums

* createdb --locale C -E LATIN1 -T template0 -p 5436 ias_sdo_monitor

h3. Automatic startup

Add following lines in the /etc/rc.local file :

<pre>

su -l -c "/usr/lib/postgresql/9.4/bin/pg_ctl -D /var/lib/postgresql/data start" postgres

su -l -c "/usr/lib/postgresql/9.4/bin/pg_ctl -D /var/lib/postgresql/data_sums start" postgres

su -l -c "/usr/lib/postgresql/9.4/bin/pg_ctl -D /var/lib/postgresql/data_monitor start" postgres

</pre>

h3. Install additional modules

We need dblink for triggers between db so let's install postgresql-contrib-9.4 

<pre>

root@sdo-new:~# apt-get install postgresql-contrib-9.4

</pre>

Create extension dblink for each db 

ias_sdo

<pre>

root@sdo-new:$ psql ias_sdo -p5432 -U postgres

psql (9.4.6)

Type "help" for help.

ias_sdo=# CREATE EXTENSION dblink ;

CREATE EXTENSION

</pre>

ias_sdo_sums 

<pre>

root@sdo-new:$ psql ias_sdo -p5434 -U postgres

psql (9.4.6)

Type "help" for help.

ias_sdo=# CREATE EXTENSION dblink ;

CREATE EXTENSION

</pre>

ias_sdo_monitor

<pre>

root@sdo-new:$ psql ias_sdo -p5436 -U postgres

psql (9.4.6)

Type "help" for help.

ias_sdo=# CREATE EXTENSION dblink ;

CREATE EXTENSION

</pre>

To check the list of installed extensions type :

 <pre>

ias_sdo=\dx

                                 List of installed extensions

  Name   | Version |   Schema   |                         Description

</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)

# SEMMNS        maximum semaphores system-wide  

# SEMOPM        maximum operations per semop call       

# SEMMNI        maximum arrays 

#semop incresed from 32 (default value)operation to 100 (3rd value )

# kernel.sem = 250      32000   32      128

kernel.sem = 250 32000 100 128

In order to  apply changes :#This sets the  OS receive buffer size for all types of connections (default value 212992)

#net.ipv4.tcp_wmem = 4096       16384   4194304

net.ipv4.tcp_no_metrics_save = 1

# Increase number of incoming connections backlog

# The tcp_mem variable defines how the TCP stack should behave when it comes to memory usage. ... 

#The first value specified in the tcp_mem variable tells the kernel the low threshold. 

#Below this point, the TCP stack do not bother at all about putting any pressure on the memory usage by different TCP sockets. ... 

#The second value tells the kernel at which point to start pressuring memory usage down. ... The final value tells the kernel how many

# memory pages it may use maximally

# net.ipv4.tcp_mem = 1543347    2057796 3086694

net.ipv4.tcp_mem = 786432 1048576 26777216

</pre>

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

<pre>

# sysctl -p

</pre>

</pre>

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

<pre>

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

</pre>

and replace the path of scp binary :

<pre>

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

</pre>

h2. 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 :

<pre>

$ ssh-keygen -t rsa

</pre>

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 :

<pre>

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

</pre>

In order to test the connection :

<pre>

$ ssh jsocexp@jsocport.stanford.edu -p55000

</pre>

Note : the IP of the server has to be declared to the jsoc

h2. NetDRMS Replication Config

%{color:red}To be check if we keep that here or not%

To prevent from deleting files 

<pre>

cd logs/SUM ; scp production@sdo:/usr/local/netdrms/install-config-files/sum_rm.cfg .

</pre>

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

<pre>

$ mkdir tmp

</pre>

Create config file from template 

<pre>

$ cd base/drms/replication/etc

cp repclient.template.cfg ias.repclient.cfg

</pre>

Define node in file : [[/usr/local/netdrms_current/base/drms/replication/etc/ias.repclient.cfg]]

In our case :

<pre>

node=IASprod

</pre>

There are 4 new fields in the new version of repclient (see Art mail June 11, 2016)

<pre>

#kRSBaseURL=<base URL for all Slony services>

kRSBaseURL=http://jsoc.stanford.edu/cgi-bin/ajax

#kSubService=<URL of the subscription service>

kSubService=${kRSBaseURL}/request-subs.py

#kPubListService=<URL of the publication-list service>

kPubListService=${kRSBaseURL}/publist.py

#kSubXfer=<URL of the file transfer directory>

kSubXfer=http://jsoc.stanford.edu/subscription

</pre>

h2. NetDRMS Subsribe list Config

Create config subscribe file from template 

<pre>

$ cd base/drms/replication/etc

cp subscribe_list.template.cfg ias.subscribe_list.cfg

</pre>
