Install antivirus for Ubuntu

Download and install AVG

After installed Ubuntu, I would highly recommend to proceed with patches update and install the antivirus. The chances of Ubuntu affected by virus are rare. However, if you are connected within the network, it is recommended to have one. At this moment, I am using AVG 7.5.51 antivirus to protect my file from viruses.

You can download the free AVG from here (.deb). Once downloaded, right click and select Open with “GDebi Package Installer”. Follow the instructions carefully.

Click on the Install Packages button.


Installing..please wait.


Click the close button.


Launch the program and do the update
Once the installation done, you can start AVG by going to Applications -->Accessories -->AVG for Linux Workstation. Do the update to download the latest virus definition.


If you encountered the update problem with the message below, you may need to configure the right permission.


Open the User and Groups panel.


Click on Unlock button and sign in as the power user. Click on the Manage Groups button.


Select the avg group and click on the Properties button.



Tick on the user to assign to AVG group.


Logout and do the update again. You should able to retrieve the update.


Alternative, at terminal you can type sudo avgupdate -o to download the update. The -o parameter indicate online update from the Internet.

Remote Access To MySQL Database

Configure my.cnf
1. We will need to edit the my.cnf file. I am assuming you are using GNOME, so open the terminal and type sudo gedit /etc/mysql/my.cnf

2. Change the bind-address to your server IP address (not to 127.0.0.1). Example, I found out my server IP is 192.168.30.30 by using the ifconfig command. So here are the changes,
bind-address = 192.168.30.30

3. Be sure to comment out the skip-networking.
# skip-networking

4. Save and close the file.

Create MySQL New User Account
** Assuming to create the superuser having all privileges and accessed from localhost and other host.
5. Open terminal and start the mysql program.

6. Type this:
mysql> GRANT ALL PRIVILEGES ON *.* TO 'some_user’@'localhost'
-> IDENTIFIED BY 'some_password' WITH GRANT OPTION;
mysql> GRANT ALL PRIVILEGES ON *.* TO 'some_user'@'%'
-> IDENTIFIED BY 'some_password' WITH GRANT OPTION;

7. Restart the MySQL server by open the terminal and type sudo /etc/init.d/mysql restart

**You can install KDE desktop instead of GNOME. However, this is up to your taste. To install KDE, type the command sudo apt-get install kubuntu-desktop

Install JDK and JRE (Java)
Step 8: Open the terminal. Applications --> Accessories --> Terminal


Step 9: Type sudo apt-get install sun-java6-jdk


Step 10: After successful install, you can do some verification to find out the installed JDK and JRE version. At the terminal, type javac –version for JDK and java –version for JRE.



Install Apache Tomcat 5.5
**Before installing the Tomcat 5.5, you will need to ensure that you had installed JDK and JRE.

Step 11: Download the tomcat 5.5 from http://tomcat.apache.org/ and saved it to desktop. Here, apache-tomcat-5.5.26.tar.gz been used.
Step 12: Right click on the file and click on Extract Here


Step 13: Rename the folder to tomcat for easier to remember the folder name.
Step 14: Is good idea to move the tomcat to /usr/local directory.
Type the command sudo mv tomcat-on-your-desktop-path /usr/local


**You need to tell the tomcat where the JDK has been installed and to do this you need to define the JAVA_HOME environment variable in .bashrc file.

Step 15: You are about to edit the .bashrc file. Please backup the file first before make any changes. The .bashrc is a hidden file and is located in your home directory.




Step 16: Right click on the .bashrc and select Open with “Text Editor”.

**Alternatively, at terminal, type the command gedit ~/.bashrc (GNOME) or kate ~/.bashrc (KDE)

Step 17: At the end of the file type export JAVA_HOME=/usr/lib/jvm/java-6-sun and save the file.


Start and Stop tomcat
Step 18: At terminal, type sh /usr/local/tomcat/bin/startup.sh
Step 19: You can verify the success installation by open the Mozilla Firefox browser and browse to http://localhost:8080/
Step 20: At terminal, type sh /usr/local/tomcat/bin/shutdown.sh

Install MySQL Query Browser.
Step 22: At terminal, type sudo apt-get install mysql-query-browser

Install MySQL Administrator
Step 23: At terminal, type sudo apt-get install mysql-admin

**I am assuming that you have the experience to do the deployment by yourself. All you need to do now, are:
-create all the necessary database, tables and fields,
-you will place your .war file into /usr/local/tomcat/webapps,
-start the tomcat....
