How to Pick Best Stocks in Share Market

Image
When thinking about investments, 3 things come to my mind, in Sri Lankan context. Buy real state in a suburb or a town that is fast growingPut in a Fixed Deposit in a bankInvest in the stock market As the current FD rates are in declining phase, it did not really come as a good option to me at the moment of writing this. Hence I thought to investigate a bit on investing in the share market as it doesn't really need a larger amount of money as to by a property as in option 1.
Below is an insightful speech by the richest person in Sri Lanka, who is known as a business magnate, 'Mr. Dhammika Perera', explaining how he started with share market (while the overall speech highlights many important facts, he specifically talks about share market from 6minutes and 26 seconds. Speech is in Sinhalese).

One thing he said, captured me that do not enter a business if you do not know about it. He also emphasized that it's the knowledge we should seek, not money, which surprised me t…

Install Liferay over a MySQL Database

With this post I will share how to get started with Liferay Portal including initial configurations and login.

Environment: Linux

Pre-requisites :


Let's download the Liferay pack from here.

I got the Community Edition of bundle with Tomcat.

Extract it to a folder of your choice, let's call the extracted folder LR_HOME. Ok, the resources are ready.. Let's go..

MySQL

Login to MySQL. If you just installed following command will do.

mysql -uroot -p

Enter the password (default root).

Create database to be used for Liferay.

create database lportal;

Create user for Liferay.
create user 'lr_user'@'localhost' identified by 'user123';


Give access to the created database for this user.
grant all privileges on lportal.* to 'lr_user'@'localhost' with grant option;

Mysql work is over now. Let's go to Liferay.

LifeRay

Go to LR_HOME.
Inside LR_HOME create file with the name 'portal-ext.properties'. This is an option provided by the Liferay architecture to override default configurations.
Copy the following content to the file.

#

#MySQL

#

jdbc.default.driverClassName=com.mysql.jdbc.Driver

jdbc.default.url=jdbc:mysql://localhost/lportal?

useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false

jdbc.default.username=lr_user

jdbc.default.password=user123

Fill the values according to the created database.

Go inside the tomcat folder in LR_HOME and issue the following command to start it.
bin/startup.sh


This will trigger the start and to see how it goes issue the following command to observe the logs.
tail -f logs/catalina.out

This will take some time at start up, since it is creating the databases. It will finally print server started in ?? ms and a new window will be automatically open in Firefox for 'http://localhost:8080/'. This is the Liferay Portal welcome page.





Login as the default admin 'test@liferay.com' with password 'test', this will get us through wizard and allow us to change the default password.

Now we are in the portal.....
Cheers!
