一. tomcat安装配置

 1. 什么是tomcat

 Tomcat就是用来解析jsp程序的一个软件

Tomcat是Apache 软件基金会（Apache Software Foundation）的Jakarta项目中的一个核心项目，由Apache、Sun和其他一些公司及个人共同开发而成。  

 Tomcat是一个轻量级应用服务器，在中小型系统和并发访问用户不是很多的场合下被普遍使用，是开发和调试JSP程序的首选。


2.安装GDK

JDK(Java Development Kit) 是 Java 语言的软件开发工具包(SDK)。没有JDK的话，无法编译Java程序。


下载jdk    本篇使用的版本为jdk-8u45-linux-i586.tar.gz


[[email protected] ~]# tar zxvf jdk-8u45-linux-i586.tar.gz

[[email protected] ~]# mv jdk1.8.0_45 /usr/local/

[[email protected] ~]# vi /etc/profile.d/java.sh   


JAVA_HOME=/usr/local/jdk1.8.0_45

JAVA_BIN=/usr/local/jdk1.8.0_45/bin

JRE_HOME=/usr/local/jdk1.8.0_45/jre

PATH=$PATH:/usr/local/jdk1.8.0_45/bin:/usr/local/jdk1.8.0_45/jre/bin

CLASSPATH=/usr/local/jdk1.8.0_45/jre/lib:/usr/local/jdk1.8.0_45/lib:/usr/local/jdk1.8.0_45/jre/lib/charsets.jar

[[email protected] ~]# . /etc/profile.d/java.sh

[[email protected] ~]# java -version   //查看安装java的版本
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) Client VM (build 25.45-b02, mixed mode)

 

3.安装tomcat

[[email protected] ~]# cd /usr/local/src/

[[email protected] src]# wget http://apache.fayea.com/tomcat/tomcat-7/v7.0.62/bin/apache-tomcat-7.0.62.tar.gz

[[email protected] src]# tar zxf apache-tomcat-7.0.62.tar.gz

[[email protected] src]# mv apache-tomcat-7.0.62 /usr/local/tomcat
[[email protected] src]# cp -pv /usr/local/tomcat/bin/catalina.sh /etc/init.d/tomcat
"/usr/local/tomcat/bin/catalina.sh" -> "/etc/init.d/tomcat"
[[email protected] src]# vi /etc/init.d/tomcat    //从第二行加入


# chkconfig: 2345 63 37

# description: tomcat server init script

# Source Function Library

. /etc/init.d/functions

JAVA_HOME=/usr/local/jdk1.8.0_31

CATALINA_HOME=/usr/local/tomcat

 
[[email protected] src]# chmod 755 /etc/init.d/tomcat 
[[email protected] src]# chkconfig --add tomcat
[[email protected] src]# chkconfig tomcat on

[[email protected] src]# 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/local/jdk1.8.0_45
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.

[[email protected] src]# ps aux |grep tomcat

4.配置tomcat

 更改默认启动端口：

[[email protected] src]# cd /usr/local/tomcat

[[email protected] conf]# vim conf/server.xml   //把Connector port=“8080”  改为 Connector port="80"

 

 -->

    <Connector port="80" protocol="HTTP/1.1"

               connectionTimeout="20000"

               redirectPort="8443" />

    <!-- A "Connector" using the shared thread pool-->

    <!--


5.配置新虚拟主机：

[[email protected] conf]# vi /usr/local/tomcat/conf/server.xml     //找到</Host>下一行插入新的<Host>内容如下: 


     <Host name="www.111.com" appBase="/data/tomcatweb"
        unpackWARs="false" autoDeploy="true" xmlValidation="false"
        xmlNamespaceAware="false">
        <Context path="" docBase="./" debug="0" reloadable="true" crossContext="true"/>
    </Host>

[[email protected] conf]# mkdir /data/tomcatweb

[[email protected] conf]# /etc/init.d/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/local/jdk1.8.0_45
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
[[email protected] conf]# /etc/init.d/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/local/jdk1.8.0_45
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
[[email protected] conf]# netstat -lnp |grep 80
