Dspce

Required Software

Operating System:Linux: Redhat/Fedora, Suse,Mandrake, Debian

etc.Unix: Solaris (Sun system), - ( HP UX Hewlett

)Packard , AIX (IBM), Mac OS X Mail server (Sendmail/postfix) RDBMS (postgres/oracle) DSpace Java compiler (jdk) Java Servlet Container Ant

Java build tool, similar to make in the world of ‘C’Complies java programs of dspace source code,

generates war files

Role of RDBMSDatabase backend (postgres/oracle) of

DSpace, stores information on:CommunitiesCollectionMembers - passwordsE-groups etc.

Step1: Linux InstallationStrongly advise to Load Linux fully unless

you are a Linux GuruMake sure the following are installed

Mail serverCopy all the files provided on CD-ROM

tar.gz files in /dspace directoryOr Download the following (or latest) files

from Internet jdk1.5.0_02.tar.gz (java compiler) apache-ant-1.7.0-bin.tar.gz (ant) postgresql-8.2.7.tar.gz (RDBMS) apache-tomcat-5.5.25.tar.gz (servlet container) postgresql-8.3-603.jdbc2.jar (jdbc driver for

postgres) dspace-source-1.4.2.tar.gz (dspace software)

Step 2: Installation of Java

Install  Java 1.4 or later You need to login as Linux root user to install Use the command bellow to install

#cd /dspace#tar –zxvf   jdk1.5.0_02.tar.gz [to uncompress

the file]#rm /usr/bin/java [remove the original java binary

if any] #cd /usr/bin #ln -s /dspace/jdk1.5.0_02/bin/java java [create

Symbolic link to newly installed java if any]

Step 2: Installation of Java (contd..)Define java home PATH by the commands:

#JAVA_HOME=/dspace/jdk1.5.0_02 [ setting variable to point Java directory]

#export JAVA_HOME To set the environment variable JAVA_HOME

permanently (get set at the time of system boot) do the following #vi /etc/profile (open /etc/profile file) Add the two lines bellow at the end of the file.

            JAVA_HOME=/dspace/jdk1.5.0_02            export JAVA_HOMESave the file (press ESC :wq), this will set the

variable JAVA_HOME when system boots

Step 3:Configuring Mail Server

You may use any of the following mail serversSendmailPostfixExim

Note: Here sendmail is explained

Step 3: Sendmail configuration: Simple approach

Case I:If your organization has a mail server Open /etc/mail/sendmail.mc Replace the line having dnl define(`SMART_HOST', `smtp.your.provider')dnl Remove dnl and enter your mail server name Ex: define(`SMART_HOST', `nsdl.niscair.res.in')dnl

Step 3: sendmail configurationcontd..

Case II: If you want to use the same system as mail server

Comment the following lineDAEMON_OPTIONS(`Port=smtp,Addr=12

7.0.0.1, Name=MTA')dnlEx:dnl #

DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

Step 3: sendmail configurationcontd..

Save the file (press ESC :wq) Run

#m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

#service sendmail restart OR#/etc/init.d/sendmail restart

Step 4: Apache-ant installation Check apache ant is already installed or not

using the command: #which ant You need to login as Linux root user If not installed type the following commands to

install #cd /dspace#tar -zxvf apache-ant-1.7.0-bin.tar (extract

files)

Step 4: Apache-ant installationDefine a path to the apache ant binary by the

commands #PATH=$PATH:/dspace/apache-ant-1.7.0 /bin #export PATH

To add apache-ant path in  PATH variable permanently do the following Open the file /etc/profile and add the two line below

towards the end of the file. #vi /etc/profile #PATH=$PATH:/dspace/apache-ant-1.7.0 /bin #export PATH

Save the file (Press ESC :wq)

Step 5: PostgreSQL installationYou need to become Linux root user to

install postgresqlUse the following commands to install

#cd /dspace #tar -zxvf postgresql-8.2.7.tar.gz (extract files) #cd /dspace/postgresql-8.2.7 #./configure (it will install postgres in

/usr/local/pgsql directory) #gmake #gmake install #useradd postgres [ create postgres user] #mkdir /usr/local/pgsql/data #chown -R postgres /usr/local/pgsql/data (change

owner of the data directory to postgres) #su - postrgres

Step 5: PostgreSQL installation(contd..)

Start posgres by doing the following $/usr/local/pgsql/bin/initdb -D

/usr/local/pgsql/data $/usr/local/pgsql/bin/pg_ctl -D

/usr/local/pgsql/data start Create a dspace database, owned by the dspace –a PostgreSQL

user by doing the following $/usr/local/pgsql/bin/createuser -U postgres -d -

A -P dspace [Enter a password for the DSpace database]

$/usr/local/pgsql/bin/createdb -U dspace -E UNICODE dspace 

$vi /usr/local/pgsql/data/postgresql.conf uncomment the line starting: listen_addresses = 'localhost' (i.e. delete # at

the beginning of line) $vi /usr/local/pgsql/data/pg_hba.conf

add follwing line in the section # IPv4-style local connections

host dspace dspace 127.0.0.1 255.255.255.255 md5

Logout from postgres user #exit

Step 6: Installation of Apache Tomcat

You have to become root user and type the following commands #cd /dspace #tar -zxvf apache-tomcat-5.5.25.tar.gz [extract files]

 Set the environment variable JAVA_OPTS="-Xmx512M -Xms64M -Dfile.encoding=UTF-8" by doing the following #JAVA_OPTS="-Xmx512M -Xms64M -

Dfile.encoding=UTF-8" #export JAVA_OPTS

To make it permanent do the following: # vi /etc/profile and add the two line below towards the end of the file.

JAVA_OPTS="-Xmx512M -Xms64M -Dfile.encoding=UTF-8"

export JAVA_OPTS Save the file (type ESC :wq)

Step 6: Installation of Apache Tomcat # vi /dspace/apache-tomcat-5.5.25/conf/server.xml

locate the following section <!-- Define a non-SSL HTTP/1.1 Connector on port

8080 --> <Connector port="8080" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" />

            and add the line URIEncoding="UTF-8" in this section like         <!-- Define a non-SSL HTTP/1.1 Connector on

port 80 --> <Connector port="80" maxThreads="150" minSpareThreads="25"     maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" URIEncoding="UTF-8" />

Save the file (press ESC :wq)

Step 7: Installation of Dspace You have to login as Linux root user Create the DSpace Linux user by using the commands

#groupadd dspace [create group] #useradd dspace –g dspace [ create dspace user] #chown -R dspace.dspace /dspace/apache-tomcat-5.5.25 [ change the

owner and group of tomcat directory to dspace, so as to run as dspace user

#cd /dspace #tar -zxvf dspace-source-1.4.2.tar.gz

It creates a directory name like dspace-1.4.2-source Copy jdbc driver for postgresql to /dspace/dspace-1.4.2-source/lib

directory. To do this perform the following: Copy a jdbc driver for postgresql i.e. postgresql-8.3-603.jdbc2.jar file

to /dspace/dspace-1.4.2-source/lib #cp /dspace/ postgresql-8.3-603.jdbc2.jarr /dspace/dspace-1.4.2-

source/lib #chown -R dspace.dspace /dspace/dspace-1.4.2-source [ change the

owner and group of dspace directory to dspace]

Step 7: Installation of Dspacecontd.. #su -l dspace $cd /dspace/dspace-1.4.2-source Open the file /dspace/dspace-1.4.2-source/config/dspace.cfg and set the

following properties $vi /dspace/dspace-1.4.2-source/config/dspace.cfg         dspace.url = [like http://192.168.3.203/dspace]         dspace.hostname = [hotsname or IP address of server] dspace.name =[ dspace name like name of your Institution eg. NISCAIR

Digital Library]         db.password = [the password you entered in the last step of

postgesql installation]         mail.server =[hostname or IP address of server ex.

mail.niscair.res.in]         mail.from.address = [email address]         feedback.recipient =[email address]         mail.admin = [email address of admin]         alert.recipient =[email address (not essential but very useful!)] Save the file $cd /dspace/dspace-1.4.2-source

Step 7: Installation of Dspacecontd..

Compile and install DSpace by doing the following $/dspace/apache-ant-1.7.0 /bin/ant fresh_install $cp /dspace/dspace-1.4.2-source/build/*.war /dspace/apache-

tomcat-5.5.25/webapps/dspace/ Define CLASSPATH for dspace classes by doing

following $vi /dspace/dspace-1.4.2-source/bin/dsrun

Append following lines at the end of file CLASSPATH=$CLASSPATH:/dspace/apache-tomcat-

5.5.25/webapps/dspace/WEB-INF/classes FULLPATH=$CLASSPATH:$jJARS:$DSPACEDIR/

config Create an initial administrator account by the

command $/dspace/dspace-1.4.2-source/bin/create-administrator You need to provide some information like admin user

name, email ID and so on

Step 7: Installation of Dspacecontd..

Start tomcat by the command $/dspace/apache-tomcat-5.5.25 /bin/startup.sh

Point your browser to the URL: http://HOSTNAME_OR_IP_ADDRESS_OF_SERVER/dspace

Access admin UI by point your browser to the URL: http://HOSTNAME_OR_IP_ADDRESS_OF_SERVER/dspace/dspace-admin

eg. http://192.168.3.203/dspace

Installation of Dspace- Summary Dspace is based on open source technlogy The installation process is some what complex

for new users The following components should properly work :

Postgresql serverJdbc driver for postgres serverApache tomcat

Initially there may be few errors related to above components if not properly installed

Cron jobs To perform certain task periodically we may use cron jobs by typing

following command:# crontab -e # Send out subscription e-mails at 01:00 every day

0 1 * * * /dspace/bin/sub-daily# Run the media filter at 02:00 every day

0 2 * * * /dspace/bin/filter-media# Generate full-text index at 2.15 an

15 2 * * * /dspace/bin/index-all# Clean up the database nightly at 2.40am

40 2 * * * vacuumdb --analyze dspace > /dev/null 2>&1" > /var/spool/cron/dspace

* * * * *Minute 0-59 Hour 0-23 (0 =

midnight)Day 1-31 Month 1-12 Weekday 0-6 (0

= Sunday)

Starting apache tomcat on bootTo make your repository start at the

boot time adds the following to /etc/rc.d/rc.local

su –l dspace –c ‘/dspace/apache-tomcat-5.5.25/bin/startup.sh

Trouble shooting..

Check your environment variable by giving the following commands

echo $PATHecho $JAVA_HOMESee whether java’s bin directory is in your PATHJAVA_HOME is pointing to Java directoryChange your /dspace/.bash_profile

Trouble shooting: while fresh_install

Mostly you get database related errors, the cause could beYou did not copy jdbc drivers in dspace-

source/lib directoryOr changes in the postgresql .conf file were

not made at all, or done improperly

Trouble shooting: Once you launch DSpace

If you do not see dspace on the screenTomcat was not launchedOr the port (8080) was already in useYou started tomcat second timeSolutionKill tomcat if you have started second time (using

ps –a | grep java or killall javaChange to another port in

tomcat/config/server.xml Check $TOMCAT-HOME/logs/catalina.out For specific problem identification

Troubleshooting: Internal System Error

Most common error message To generic and is not specific The reasons could be many

Check /dspace/log/dspace.log file, which may provide the specific problem

Trouble-shooting: Fails to sendmal

Mail configuration is wrong You did not make mail server entry in

/dspace/conf/dspace.cfg file DNS problem You do not have FQDN (Fully Qualified Domain

Name) for you systemIt should hostname.domainname

Ex: localhost.localdomain (not just localhost)nsdl.niscair.res.in ( not jst nsdl)
