Apache Solr 4.6.1 Tomcat7 Setup on Ubuntu 12.04 ( Simple and Clear Steps )

We need a tomcat server to install and run Apache solr search engine .

Setup Java run time environment by following blog post 

http://gagannaidu.blogspot.in/2013/06/installation-of-oracle-java-7-on-ubuntu.html

Install Tomcat 7 and Solr 4.6

sudo apt-get install tomcat7 tomcat7-admin

Click here to download Solr : http://apache.tradebit.com/pub/lucene/solr/4.6.1/solr-4.6.1.zip

tar zxvf solr-4.6.1.tgz

sudo mv solr-4.6.1 /usr/share/solr

Setup Solr on Tomcat

sudo cp /usr/share/solr/example/webapps/solr.war /usr/share/solr/example/multicore/solr.war 

From the Apache Solr lib, copy all the jar files to the tomcat lib

sudo cp -r solr/example/lib/ext/* /usr/share/tomcat7/lib

sudo cp -r solr/example/resources/log4j.properties /usr/share/tomcat7/lib

Edit /usr/share/tomcat7/lib/log4j.properties and set your log path by setting

solr.log=/usr/share/solr

Now add solr to the Catalina config

cd /etc/tomcat7/Catalina/localhost

sudo gedit solr.xml

add the following to solr.xml

<Context docBase="/usr/share/solr/example/multicore/solr.war" debug="0" crossContext="true">

  <Environment name="solr/home" type="java.lang.String" value="/usr/share/solr/example/multicore" override="true" />

</Context>

Setup Tomcat Manager

sudo gedit /etc/tomcat7/tomcat-users.xml

add the tomcat user within the users block:

<tomcat-users>

  <role rolename="manager-gui"/>

  <user username="giluxe" password="giluxe" roles="manager-gui"/>

</tomcat-users>

sudo chown -R tomcat7 /usr/share/solr/example/multicore

Test tomcat

sudo service tomcat7 restart

Test Solr

Navigate to  http://localhost:8080/solr

Note : If you get any problem while restarting tomcat   " no JDK found - please set JAVA_HOME "

follow this step 

sudo gedit /etc/default/tomcat7  

uncomment JAVA_HOME path . 

INSTALLATION OF ORACLE JAVA 7 ON UBUNTU 12.04

This post will be useful to install oracle java 7 on ubuntu .

If you have the OpenJDK/JRE installed on your system, you can remove it by typing the following at the command line:

Type/Copy/Paste: sudo apt-get purge openjdk-\*  

This command will completely remove OpenJDK/JRE from your system .

 Create java folder in usr/lib/jvm , you can create it by following command line :

Type/Copy/Paste: sudo mkdir -p /usr/lib/jvm/java

This command will create a directory to hold your Oracle Java JDK and JRE binaries.

 Download jdk and jre from here

Extract that files and copy and paste it into usr/lib/jvm/java folder 


Edit the system PATH file /etc/profile and add the following system variables to your system path

Type/Copy/Paste: sudo gedit /etc/profile

Scroll down to the end of the file using your arrow keys and add the following lines below to the end of your /etc/profile file:  

Type/Copy/Paste:

JAVA_HOME=/usr/lib/jre/java/jdk1.7.0_21
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
JRE_HOME=/usr/lib/jre/java/jre1.7.0_21
PATH=$PATH:$HOME/bin:$JRE_HOME/bin
export JAVA_HOME
export JRE_HOME
export PATH

Save the /etc/profile file and exit.

Inform your Ubuntu Linux system where your Oracle Java JDK/JRE is located. This will tell the system that the new Oracle Java version is available for use. 

Type/Copy/Paste: sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jre/java/jre1.7.0_21/bin/java" 1 

this command notifies the system that Oracle Java JRE is available for use .

Type/Copy/Paste: sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jre/java/jdk1.7.0_21/bin/javac" 1 

this command notifies the system that Oracle Java JDK is available for use

Type/Copy/Paste: sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jre/java/jre1.7.0_21/bin/javaws" 1 

this command notifies the system that Oracle Java Web start is available for use

Inform your Ubuntu Linux system that Oracle Java JDK/JRE must be the default Java.

Type/Copy/Paste: sudo update-alternatives --set java /usr/lib/jre/java/jre1.7.0_21/bin/java  
this command will set the java runtime environment for the system

Type/Copy/Paste: sudo update-alternatives --set javac /usr/lib/jre/java/jdk1.7.0_21/bin/javac

this command will set the javac compiler for the system

Type/Copy/Paste: sudo update-alternatives --set javaws /usr/lib/jre/java/jre1.7.0_21/bin/javaws

this command will set Java Web start for the system

Reload your system wide PATH /etc/profile by typing the following command: 

Type/Copy/Paste: . /etc/profile

Note your system-wide PATH /etc/profile file will reload after reboot of your Ubuntu Linux system

Test to see if Oracle Java was installed correctly on your system. Run the following commands and note the version of Java:

Type/Copy/Paste: java -version 
 this should display

java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b21)
Java HotSpot(TM) Server VM (build 23.1-b03, mixed mode)

Type/Copy/Paste: javac -version  

javac 1.7.0_21

That's all you just installed Oracle Java on your Linux system .

Note : Check your JAVA_PATH and JRE_PATH in terminal by following commands :

Type/Copy/Paste: echo $JAVA_HOME

it will display   /usr/lib/jvm/java/jdk1.7.0_21


Type/Copy/Paste: echo $JRE_HOME

it will display  /usr/lib/jvm/java/jre1.7.0_21


If terminal show this paths then all is set . Sometimes you may not get this paths correctly that time you should follow this steps

Goto your home folder and press CTRL + F , you can get .bashrc file  in that file you can export your java path add following line at end of the file or modify JAVA_HOME

 export JAVA_HOME=/usr/lib/jvm/java/jdk1.7.0_21


That's all everything done ....

Installation of Joomla on Ubuntu 11.10 / 12.04

1. After installing LAMP, add support and enable Joomla in Apache with the following commands:

cd /etc/apache2/

sudo cp sites-available/default sites-available/joomla

sudo a2ensite joomla

sudo /etc/init.d/apache2 restart


2. Next, we will create a MySQL database and MySQL user to use during the installation of Joomla later on. I will mark them in red, you can rename them to whatever you want.

- Via the terminal sign in to the MySQl server with this command:

mysql -u root -p 

- Create a MySQL database with this command:

create database joomla;

- We need also to create a MySQL user having the same name of the MySQL database with this command (replace "1234" with any password of your choice):

CREATE USER 'joomla'@'localhost' IDENTIFIED BY '1234';

- Grant now this user all access privileges on the already created database:

GRANT ALL PRIVILEGES ON joomla.* TO 'joomla' IDENTIFIED BY '1234';

Exit the MySQL server with this command:

exit

3. IIt's time now to download and install Joomla. The installation folder will be in /var/www/joomla. Via the terminal, run these commands:

cd /tmp && wget -O Joomla_2.5.7-Stable.zip http://goo.gl/41TMS

sudo mkdir /var/www/joomla

sudo unzip Joomla_2.5.7-Stable.zip -d /var/www/joomla

sudo chown -R www-data.www-data /var/www/joomla/

- Start now the installation of Joomla 2.5.1 by opening one of these two links:

http://127.0.0.1/joomla

or 

http://localhost/joomla

MySQL 5.0 Installation 

MySQL is a fast, multi-threaded, multi-user, and robust SQL database server. It is intended for mission-critical, heavy-load production systems as well as for embedding into mass-deployed software.

Installation 
To install MySQL 5.0, Run the following command from a terminal prompt:
sudo apt-get install mysql-server

During the installation process you will be prompted to enter a password for the MySQL root user.
Once the installation is complete, the MySQL server should be started automatically. You can run the following command from a terminal prompt to check whether the MySQL server is running:
sudo netstat -tap | grep mysql

When you run this command, you should see the following line or something similar:

tcp        0      0 localhost.localdomain:mysql           *:* LISTEN -

If the server is not running correctly, you can type the following command to start it:
sudo /etc/init.d/mysql restart

Configuration

You can edit the /etc/mysql/my.cnf file to configure the basic settings -- log file, port number, etc.
For example, to configure MySQL to listen for connections from network hosts, change the bind_address directive to the server's IP address:

bind-address            = 192.168.0.5

[Note]     

Replace 192.168.0.5 with the appropriate address.

After making a change to /etc/mysql/my.cnf the mysql daemon will need to be restarted:

sudo /etc/init.d/mysql restart


Resources

See the MySQL Home Page for more information.

The MySQL Handbook is also available in the mysql-doc-5.0 package. To install the package enter the following in a terminal:

sudo apt-get install mysql-doc-5.0

The documentation is in HTML format, to view them enter

file:///usr/share/doc/mysql-doc-5.0/refman-5.0-en.html-chapter/index.html 

in your browser's address bar.

Run MySql Server:
Launch terminal and execute following command

mysql -h <ipaddress> -u <username> -p

for example

mysql -h localhost -u srinu -p

This will prompt for the password, once successfully entered will show you the following mysql prompt

mysql>   

Install Apache Tomcat 7 on Ubuntu
Apache has officially launched version 7.0 of the servlet container for Java applications, Tomcat. Major changes in this version, you can highlight support for Servlet 3.0 and JavaServer Pages 2.2.

Installation:

1. Install JDK
2. download the package "apache-tomcat-7.0.6.tar.gz" from http://tomcat.apache.org/download-70.cgi [tar.gz]

Now unpack it with the following command:
tar xvzf apache-tomcat-7.0.8.tar.gz

Then we let in a more appropriate directory, in our case in /usr/share/tomcat7, but can be in any directory.

We do this with the command:
sudo mv apache-tomcat-7.0.8/ /usr/share/tomcat7

Now we define the environment variables
JAVA_HOME and JRE_HOME

This file is in the "environment" in /etc. 

Command to edit the file:
sudo gedit /etc/environment

Here we record the routes where we have installed Java in my case this is as follows:

JAVA_HOME="/usr/local/jdk1.6.0_23"
JRE_HOME="/usr/local/jdk1.6.0_23/jre"

PATH="...(other path):$JAVA_HOME:$JRE_HOME"

IMPORTANT: Verify the routes where they have installed Java.

I have had some problems in defining these environment variables,
as sometimes tomcat does not recognize,
but a surefire way of recognizing that tomcat is to define the file paths inside "catalina.sh"located intomcat7/bin.

To modify this file use the command:
sudo gedit /usr/share/tomcat7/bin/catalina.sh

Now just insert the JAVA_HOME and JRE_HOME after the first line,
so the file is as follows:

#!/bin/sh
JAVA_HOME="/usr/local/jdk1.6.0_23"
JRE_HOME="/usr/local/jdk1.6.0_23/jre"
# Licensed to the Apache Software Foundation (ASF)...
#...
#...
....

Now let's configure Tomcat users,
this is done in the file "tomcat-users.xml"directory tomcat7/conf.

Unlike previous versions where the administrator should own role "manager" now it should be "manager-gui"to operate on the web administration tomcat7.

The file would be as follows:

<?xml version='1.0' encoding='utf-8'?>

<tomcat-users>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager"/>
<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<role rolename="admin"/>

<user username="usuario" password="contrasena" roles="manager-gui,admin-gui,manager,admin,manager-script,admin-script"/>
</tomcat-users>



Now you should be all ready to try tomcat7.

First we must lift the server with the following command:
sudo /usr/share/tomcat7/bin/startup.sh

With this we get the following output on console:

Using CATALINA_BASE: /usr/share/tomcat7
Using CATALINA_HOME: /usr/share/tomcat7
Using JRE_HOME: /usr/local/jdk1.6.0_20/jre
Using CLASSPATH: /usr/share/tomcat7/bin/bootstrap.jar:/usr/share/tomcat7/bin/tomcat-juli.jar
Verify that the JRE_HOME is where we define.

Now open your web browser and type the following url:

http://127.0.0.1:8080/

If we enter the administration Tomcat Manager we click on the menu or directly at URL:

http://127.0.0.1:8080/manager/html

Here we ask the user data from previous record in mind tomcat-users.xml.

I recommend testing the sample to make sure everything works ok, they are in the section "Miscellaneous" from the side menu or at the URL:
http://127.0.0.1:8080/examples/

Commands

Start server:
sudo /usr/share/tomcat7/bin/startup.sh

Stop server:
sudo /usr/share/tomcat7/bin/shutdown.sh

Tomcat should now be fully installed and operational. Enjoy!

INSTALLATION OF ECLIPSE

Here is how you can install JAVA Eclipse on Windows 7

• Decide which version you want to use. If you are using 64-bit windows 7, you should install 64-bit JAVA JDK and JAVA Eclipse. If you are using 32-bit windows 7, you should install 32-bit JAVA JDK and 32-bit JAVA Eclipse.

• Download and install JAVA JDK from here.

• After JAVA JDK is download, install it as we normally install any software on Windows.

• Download JAVA Eclipse from here.

• After you have downloaded JAVA Eclipse, extract it using any zip software like winzip, winRaR. Do not use Windows default explorer to extract files, as it may not extract files properly. It will create a folder “eclipse”, with multiple subdirectories under that.

• JAVA Eclipse is installed now. Double click eclipse.exe to run JAVA eclipse
