How to configure Tomcat7 Server with Mysql database on Amazon EC2 Amazon AMI distribution

Posso usar este tutorial:
http://wpcertification.blogspot.com.br/2014/02/install-apache-tomcat-on-amazon-ec2.html

Connect to Amazon Server:

ssh -i learnbyheart.pem ec2-user@54.173.106.139

Porem, é preciso atualizaro iptables de forma que o tomcat comece a escutar a porta 80. (A 8080 também não pegará sem os comandos abaixos):

# cria a roda da porta 80 para 8080.
sudo iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
# salva a rota.
sudo service iptables save
# reinicia a tabela de rotas.
sudo service iptables restart

Mysql Installation:
# recebe permissao de root.
sudo su

# instala o pacote do mysql.
yum install mysql mysql-server mysql-libs

# inicia o servico.
service mysqld start

# configura a inicializacao.
chkconfig --levels 235 mysqld on

# inicia as configuracoes (IMPORTANTE - para configurar os privilegios iniciais).
mysql_secure_installation

mysql -u root -p
CREATE DATABASE db_learnbyheart;
CREATE USER 'learnbyheart'@'localhost' IDENTIFIED BY 'lbhpwd';
GRANT ALL ON db_learnbyheart.* TO 'learnbyheart'@'localhost';
FLUSH PRIVILEGES;

How to upload file
(don't forget to restart tomcat, or reload axis... to make the updates take effects)

•  scp -i learnbyheart.pem /usr/share/tomcat-7.0.34/webapps/axis2/WEB-INF/services/Cloud.aar ec2-user@54.173.106.139:~
• scp -i learnbyheart.pem /usr/share/tomcat-7.0.34/webapps/axis2/WEB-INF/services/Cloud.aar ec2-user@54.173.106.139:/usr/share/tomcat7/webapps/axis2/WEB-INF/services/

How to install Tomcat7

[this process was accomplished using Ubuntu 12.04 LTS, Tomcat 7 and Eclipse Standard Keplerr 4.3]

Follow this tutorial (from step 1 to 9):
http://gridlab.dimes.unical.it/lackovic/eclipse-tomcat-ubuntu-jersey/

Notes for the above tutorial:
Download and install eclipse manually, from:
http://www.eclipse.org/downloads/packages/eclipse-standard-43/keplerr

Before starting up the tomcat7 server:
sudo mkdir /usr/share/tomcat7/logs

Before shutting down the tomcat7 server:
sudo mkdir /usr/share/tomcat7/conf
sudo cp /etc/tomcat7/server.xml to /usr/share/tomcat7/conf

Before creating a "Dynamic Web Project", run:
cd /usr/share/tomcat7
sudo ln -s /var/lib/tomcat7/conf conf
sudo ln -s /etc/tomcat7/policy.d/03catalina.policy conf/catalina.policy
sudo chmod -R 777 /usr/share/tomcat7/conf

If you try to add the Tomcat Server v7.0, and the server name doesn't appear:
Close Eclipse
cd ~/workspace/.metadata/.plugins/org.eclipse.core.runtime/.settings/   
rm org.eclipse.jst.server.tomcat.core.prefs   
rm org.eclipse.wst.server.core.prefs
Restart Eclipse
