22. Unzip Dspace Installer
cd /srv
sudo unzip /srv/dspace-5.7-release.zip
  * Requirement to install unzip package by using command 'sudo apt-get install zip'

23. Create user name is 'dspace'
sudo useradd -m dspace

24. Next, create database user
sudo su - postgres

createuser --username=postgres --no-superuser --pwprompt dspace
(type password 'dspace' )

  * --username=postgres ==> Login user name for logging into database to create new database user
  * --no-superuser ==> Setting new created user without 'superuser'

db.username=user1
db.password=user1
mail.server = smtp.example.com
mail.server.username=
mail.server.password=
mail.from.address = dspace-noreply@myu.edu
mail.feedback.recipient = dspace-help@myu.edu
mail.admin = dspace-help@myu.edu
handle.canonical.prefix = ${dspace.url}/handle/
handle.prefix = 123456789

29. To build DSpace Installer
cd /srv/dspace-5.7-release
mvn package
  *Wating for 20-40 Minutes (Based on speed of each internet networking)

30.Installing DSpace
cd /srv/dspace-5.7-release/dspace/target/dspace-installer
ant fresh_install

sudo vi /opt/tomcat/webapps/host-manager/META-INF/context.xml   or
sudo nano /opt/tomcat/webapps/host-manager/META-INF/context.xml

comment or remark the next line below of both file the above
so it will change from

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />

to be

  <!-- <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />  -->


33. Then restart service tomcat with command 'sudo systemctl restart tomcat'

34.Creating web app. through UI by logging into  'http://[host]:8080/manager'
example: 
http://dspaceweb.com:8080/manager    or
http://9.9.9.9:8080/manager
(if found error  403 Access Denied, please go back to check no.32 again !!)

  Context Path (required) ==> select path on web site such as: /solr
  WAR or Directory URL ==> path of project such as: /srv/dspace/webapps/solr

35. Otherwise, creating web app. into '/opt/tomcat/conf/server.xml'
sudo nano /opt/tomcat/conf/server.xml

by adding next line below
<Context path="" docBase=""></Context>     within tag Host  </Host>  !!
For example,
<Context path="/jspui" docBase="/srv/dspace/webapps/jspui"></Context>
<Context path="/oai" docBase="/srv/dspace/webapps/oai"></Context>
<Context path="/rdf" docBase="/srv/dspace/webapps/rdf"></Context>
<Context path="/rest" docBase="/srv/dspace/webapps/rest"></Context>
<Context path="/solr" docBase="/srv/dspace/webapps/solr"></Context>
<Context path="/sword" docBase="/srv/dspace/webapps/sword"></Context>
<Context path="/sword2" docBase="/srv/dspace/webapps/sword2"></Context>
<Context path="/xmlui" docBase="/srv/dspace/webapps/xmlui"></Context>

36. Creating Administrator account to manage Dspace system
/srv/dspace/bin/dspace create-administrator

37. Opening REST API Service
 by setting web app point to '/srv/dspace/webapps/rest'
So, it should be
<Context path="/rest" docBase="/srv/dspace/webapps/rest"></Context>

  * In case of using REST API with common http,
it need to be comment out in '/srv/dspace/webapps/rest/WEB-INF/web.xml'
nano /srv/dspace/webapps/rest/WEB-INF/web.xml

  * by comment out at '<security-constraint>'
change from
<security-constraint>  .......................................
........................................................................
</security-constraint>

  *and next run command 'ant -Dconfig=/srv/dspace/config/dspace.cfg'
in the directory of '/srv/dspace-5.7-release/dspace/target/dspace-installer'

  * Then restart service tomcat with command 'sudo systemctl restart tomcat'

39.  Before to be continue the next step, please try to do backup /ROOT in
/opt/tomcat/webapps  by using this command

sudo cp -avr /opt/tomcat/webapps/ROOT /opt/tomcat/webapps/ROOT-backup

Next, In case of using jspui, you need to be copy file from directory '/srv/dspace/webapps/jspui'
to replace into '/opt/tomcat/webapps/ROOT'
by using this command

cp -avr /srv/dspace/webapps/jspui/* /opt/tomcat/webapps/ROOT
chown -R tomcat:tomcat /opt/tomcat/webapps/ROOT


and for solr,
need to be copy file from directory '/srv/dspace/webapps/solr' to replace into
/opt/tomcat/webapps/solr
