Tomcat + MySQL

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

方案一：  Tomcat                   Tomcat1

方案二：  Apache (负载均衡器)   Tomcat2

Tomcat3

Tomcat1

方案三：  Nginx (负载均衡器)   Tomcat2

Tomcat3

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

一、Tomcat Http Server

1. JAVA环境

\[root@Tomcat ~\]\# 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

安装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

定义Tomcat所需的环境变量

\[root@master local\]\# vim /etc/profile //定义Tomcat环境变量

CATALINA\_HOME=/usr/local/tomcat //Tomcat安装目录

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

启动Tomcat

方法一：

\[root@master ~\]\# /usr/local/tomcat/bin/startup.sh //启动

Using CATALINA\_BASE:   /usr/local/tomcat

Using CATALINA\_HOME:   /usr/local/tomcat

Using CATALINA\_TMPDIR: /usr/local/tomcat/temp

Using JRE\_HOME:        /usr/java/jdk1.7.0\_11

Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

\[root@master ~\]\# netstat -tnlp |grep java

tcp        0      0 ::ffff:127.0.0.1:8005       :::\*                   LISTEN      6191/java

tcp        0      0 :::8009                     :::\*                        LISTEN      6191/java

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

\[root@master ~\]\# /usr/local/tomcat/bin/shutdown.sh //停止

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

方法二：System V脚本

\#\[root@master ~\]\# 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:关闭  1:关闭  2:启用  3:启用  4:启用  5:启用  6:关闭

\[root@master ~\]\# chkconfig tomcat on

\[root@master ~\]\#

\[root@master ~\]\# service tomcat stop

Using CATALINA\_BASE:   /usr/local/tomcat

Using CATALINA\_HOME:   /usr/local/tomcat

Using CATALINA\_TMPDIR: /usr/local/tomcat/temp

Using JRE\_HOME:        /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.9.x86\_64/jre/

Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

\[root@master ~\]\# service tomcat start

Using CATALINA\_BASE:   /usr/local/tomcat

Using CATALINA\_HOME:   /usr/local/tomcat

Using CATALINA\_TMPDIR: /usr/local/tomcat/temp

Using JRE\_HOME:        /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.9.x86\_64/jre/

Using CLASSPATH:      /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

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

3. 测试

二、Tomcat连接MySQL

1. 安装MySQL(见上一篇文章，如何编译mysql)

2. 为Tomcat提供连接Mysql的类文件\[root@master jsp\]\# tar xf mysql-connector-java-5.0.8.tar.gz

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

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

\[root@master jsp\]\#service tomcat stop\[root@master jsp\]\#service tomcat start

三、部署JavaCenter\_Home

1. Tomcat默认的网站目录

\[root@master jsp\]\# ls /usr/local/tomcat/webapps/ //默认网站的基目录base

docs  examples  host-manager  manager  ROOT

\[root@master jsp\]\# ls /usr/local/tomcat/webapps/ROOT //默认网站的主目录

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 \* //删除默认网站内容

2. 部署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

admin        attachment         cp.jsp           editor.jsp   image       js.jsp     network.jsp  template     xmlrpc.jsp

admincp.jsp  avatar.jsp         crossdomain.xml  errors       index.jsp   link.jsp   rss.jsp      theme

api          config.properties  data             favicon.ico  install     magic.jsp  source       userapp.jsp

app.jsp      contact.jsp        do.jsp           help.jsp     invite.jsp  META-INF   space.jsp    WEB-INF

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

\[root@master source\]\# service tomcat stop

\[root@master source\]\# service tomcat start
