Tomcat + MySQL

========================================================

Solution 1: Tomcat1

Scenario 2: Apache (Load Balancer) Tomcat2

Tomcat3

Tomcat1

Solution 3: Nginx (Load Balancer) Tomcat2

Tomcat HTTP Server

1. Java environment

[root@Tomcat ~]# java -version

java version "1.7.0_09-icedtea"

OpenJDK Runtime Environment (rhel-2.3.4.1.el6_3-x86_64)

OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)

[root@Tomcat ~]# vim /etc/profile

JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.9.x86_64/jre/

PATH=$PATH:$JAVA_HOME/bin

export JAVA_HOME PATH

[root@Tomcat ~]# source /etc/profile

[root@Tomcat ~]# env |grep JAVA

JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.9.x86_64/jre/

2. Tomcat

Install Tomcat

[root@master jsp]# tar xf apache-tomcat-7.0.34.tar.gz -C /usr/local/

[root@master jsp]# cd /usr/local/

[root@master local]# ln -s apache-tomcat-7.0.34/ tomcat

Define environment variables required for Tomcat

[root@master local]# vim /etc/profile //define Tomcat environment variables

CATALINA_HOME=/usr/local/tomcat //Tomcat installation directory

export CATALINA_HOME

[root@master local]# source /etc/profile

[root@master local]# env |grep HOME

CATALINA_HOME=/usr/local/tomcat

JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.9.x86_64/jre/

HOME=/root

start Tomcat

Method 1:

tcp 0 0 :::8080 :::* LISTEN 6191/java

[root# /usr/local/tomcat/bin/www.example.com//stop shutdown.sh

========================================================

Method 2: System V Scripting

#[root@master ~]# vim /etc/init.d/tomcat

#!/ bin/bash

# Init file for Tomcat server daemon

#

# chkconfig: 2345 96 14

# description: Tomcat server daemon

JAVA_OPTS='-Xms64m -Xmx128m'

JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.9.x86_64/jre/

CATALINA_HOME=/usr/local/tomcat

export JAVA_OPTS JAVA_HOME CATALINA_HOME

exec $CATALINA_HOME/bin/catalina.sh $*

[root@master ~]# chmod a+x /etc/init.d/tomcat

[root@master ~]# chkconfig --add tomcat

[root@master ~]# chkconfig tomcat --list

tomcat 0: Off 1: Off 2: Enabled 3: Enabled 4: Enabled 5: Enabled 6: Off

[root@master ~]# chkconfig tomcat on

[root@master ~]#

[root@master ~]# service tomcat stop

Tomcat Connection to MySQL

1. Install MySQL (see previous article, How to compile mysql)

2. Provides class files for Tomcat to connect to Mysql

[root@master jsp]# tar xf mysql-connector-java-5.0.8.tar.gz

[root@master jsp]# cd mysql-connector-java-5.0.8

[root@master mysql-connector-java-5.0.8]# cp mysql-connector-java-5.0.8-bin.jar /usr/local/tomcat/lib/

[root@master jsp]# service tomcat stop

[root@master jsp]# service tomcat start

Deployment JavaCenter_Home

1. Tomcat default website directory

[root@master jsp]# ls /usr/local/tomcat/webapps/ //base directory of default website

docs examples host-manager manager ROOT

[root@master jsp]# ls /usr/local/tomcat/webapps/ROOT //Home directory of default web site

asf-logo.png bg-nav-item.png favicon.ico tomcat.gif WEB-INF

asf-logo-wide.gif bg-nav.png index.jsp tomcat.png

bg-button.png bg-upper.png RELEASE-NOTES.txt tomcat-power.gif

bg-middle.png build.xml tomcat.css tomcat.svg

[root@master ~]# cd /usr/local/tomcat/webapps/ROOT/

[root@master ROOT]# rm -rf * //Delete default site content

2. Deploying JavaCenter_Home

[root@master jsp]# unzip JavaCenter_Home_2.0_Source_UTF8

[root@master jsp]# cd JavaCenter_Home_2.0_Source_UTF8

[root@master JavaCenter_Home_2.0_Source_UTF8]# ls

source

[root@master JavaCenter_Home_2.0_Source_UTF8]# cd source/

[root@master source]# ls

src WebRoot

[root@master source]# cd WebRoot/

[root@master WebRoot]#

[root@master WebRoot]# ls

[root@master WebRoot]# cp -rf * /usr/local/tomcat/webapps/ROOT/

[root@master source]# service tomcat stop

[root@master source]# service tomcat start
