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
[root@zhu1 ~]# tar zxvf jdk-7u40-linux-i586.tar.gz
[root@zhu1 ~]# mv jdk1.7.0_40/ /usr/local/jdk

2.设置环境变量

[root@zhu1 ~]# 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

[root@zhu1 ~]# source /etc/profile
[root@zhu1 ~]# 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

[root@zhu1 ~]# wget http://mirror.esocc.com/apache/tomcat/tomcat-7/v7.0.42/bin/apache-tomcat-7.0.42.tar.gz
[root@zhu1 ~]# tar zxvf apache-tomcat-7.0.42.tar.gz
[root@zhu1 ~]# mv apache-tomcat-7.0.42 /usr/local/tomcat

5.设置tomcat的环境变量

[root@zhu1 ~]# vim /etc/profile
export CATALINA_HOME=/usr/local/tomcat

6.测试

[root@zhu1 bin]# ./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

[root@zhu1 bin]# ./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
[root@zhu1 bin]# netstat -lntp | grep 8080
tcp        0      0 :::8080                    :::*                        LISTEN      10614/java
