How to install Sun java 1.6 on Debian Lenny

And not the OpenJDK, as sometimes some applications do not work without the SUN JDK

Edit APT sources list

# vi /etc/apt/sources.list

The original Sun Java 2 is available in the ‘non-free’ section of the Debian repositories. To enable this section first add the non-free repository to the apt sources file - the /etc/apt/sources.list should look like, - important parts are in bold:

deb lenny main non-free
deb-src  lenny main non-free
deb  lenny/updates main

Update the list of sources

apt-get update

Install java

#  apt-get install sun-java6-bin

Just follow and select all the time

How to install Tomcat 6 on Debian Lenny

Create new file

# vi /etc/apt/sources.list.d/squeeze.list

and put inside

# Repository for Squeeze, to get Tomcat6
deb squeeze main contrib non-free
deb-src squeeze main contrib non-free

Create new file

# vi /etc/apt/preferences

And put inside

Package: *
Pin: release o=Debian,a=stable
Pin-Priority: 990
Package: *
Pin: release o=Debian,a=testing
Pin-Priority: 500
Package: tomcat6,tomcat6-admin,tomcat6-common,libtomcat6-java,libservlet2.5-java
Pin: release o=Debian,a=testing
Pin-Priority: 990

Update sources

# apt-get update


# apt-get upgrade

# apt-cache search tomcat




# apt-get install -t testing tomcat6

Create new users/roles for tomcat manager

How to install MYSQL on Debian Lenny

Luckily MYSQL 5.0 is available in the default source list of APT.

# apt-cache search mysql
# apt-get install mysql-server-5.0

Open a mysql prompt

Grant access to root from any host, this is insecure for production machine but in case of continuous build machine, development this is sometimes very useful.

Let root connect not only from localhost by running

# mysql –u root –p
mysql> use mysql;
mysql> update user set host = '%' where user = 'root' and host=''
mysql> flush privileges;

Bad written code (DAO) will sometimes forces you to start MYSQL using insensitive casing table. In windows it will always work as the operating system do not make any difference between lower and upper case. In Linux, either you change your DAO’s or if you can’t, use this kind of trick:

Case insensitive table in MYSQL

# vi /etc/mysql/conf.d/lower_case_table_names.cnf

Put inside file

lower_case_table_names = 1

Restart mysql

# /etc/init.d/mysql restart

In computing, alias is a command in various command line interpreters (shells) such as Unix shells, 4DOS/4NT and Windows PowerShell, which enables a replacement of a word with another string.
