安装tomcat服务器
tomcat是一个轻量级应用服务器，运行时占用系统资源少，扩展性好，支持负载平衡。1.先安装jdk（javaDevelopmentkit)
http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html #下载对应版本的jdk
# tar zxvf jdk-7u40-linux-i586.tar.gz
# mv jdk1.7.0_40/ /usr/local/jdk 2.设置环境变量
# vim /etc/profile #在最后添加下面几行
export JAVA_HOME=/usr/local/jdk
export CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$PATH:$JAVA_HOME/bin 3.测试
# source /etc/profile
# java -version
java version "1.7.0_40"
Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
Java HotSpot(TM) Client VM (build 24.0-b56, mixed mode)
#出现此界面，说面jdk安装成功 4.安装tomcat
# wget http://mirror.esocc.com/apache/tomcat/tomcat-7/v7.0.42/bin/apache-tomcat-7.0.42.tar.gz
# tar zxvf apache-tomcat-7.0.42.tar.gz
# mv apache-tomcat-7.0.42 /usr/local/tomcat 5.设置tomcat的环境变量
# vim /etc/profile
export CATALINA_HOME=/usr/local/tomcat 6.测试
# ./catalina.sh 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/jdk
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar 7.启动tomcat查看端口
# ./startup.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/local/jdk
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
# netstat -lntp | grep 8080
tcp 0 0 :::8080 :::* LISTEN 10614/java 8.访问
