Linux上安装配置tomcat

1.下载JDK与Tomcat.
jdk下载地址:
http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
tomcat下载地址:
http://tomcat.apache.org/download-70.cgi

2.jdk安装与配置.
(1)jdk安装
rpm包:
# rpm -ivh jdk-7u55-linux-x64.rpm

tar.gz包:解压缩# mkdir /usr/java# cd /usr/java# tar -zxvf /software/jdk-7u55-linux-x64.tar.gz生成链接以便版本升级# ln -s jdk1.7.0_55 latest# ln -s latest default(2)配置环境变量# vi /etc/profileexport JAVA_HOME=/usr/java/defaultexport JAVA_BIN=$JAVA_HOME/binexport PATH=$PATH:$JAVA_HOME/binexport CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jarexport PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH使配置生效# source /etc/profile测试jdk.# java -versionjava version "1.7.0_55"Java(TM) SE Runtime Environment (build 1.7.0_55-b13)Java HotSpot(TM) 64-Bit Server VM (build 24.55-b03, mixed mode)

3.Tomcat的安装
解压缩
# mkdir /usr/local/tomcat
# cd /usr/local/tomcat
# tar -zxvf /software/apache-tomcat-7.0.54.tar.gz
生成链接以便版本升级
# ln -s apache-tomcat-7.0.54 server

启动Tomcat# cd /usr/local/tomcat/server/bin# ./startup.shUsing CATALINA_BASE: /usr/local/tomcat/serverUsing CATALINA_HOME: /usr/local/tomcat/serverUsing CATALINA_TEMDIR: /usr/local/tomcat/server/tempUsing JRE_HOME: /usr/java/defaultUsing CLASS_PATH: /usr/local/tomcat/server/bin/bootstrap.jar:/usr/local/tomcat/server/bin/tomcat-juli.jarTomcat started.测试Tomcat:打开防火墙,使外部能访问# /sbin/iptables -I INPUT -p tcp --dport 8080 -j ACCEPT# service iptables save# service iptables restart或直接修改文件/etc/sysconfig/iptables.# vi /etc/sysconfig/iptables-A INPUT -p tcp -m tcp --dport 8080 -j ACCEPT# service iptables restart在浏览器输入: http://192.168.16.133:8080如在本机可以输入: http://localhost:8080出现tomcat的页面表示安装成功.停止Tomcat# ./shutdown.sh

4.配置web管理帐号
修改文件conf/tomcat-users.xml，在元素中添加帐号密码，需要指定角色.
# vi /usr/local/tomcat/server/conf/tomcat-users.xml

5.配置web访问端口
可以修改conf目录下的文件server.xml，修改Connector元素(Tomcat的默认端口是8080)，需要重新启动Tomcat服务生效.
# vi /usr/local/tomcat/server/conf/server.xml

6.配置https安全连接(ssl加密连接)
https连接需要用到数字证书与数字签名(MD5算法)
网站https连接首先需要申请数字证书，配置加密连接器，浏览器安装证书.
·使用java的工具keytool产生数字证书
# keytool -genkey -alias tomcat -keyalg RSA
生成文件.keystore
注意:CN为主机名称，本机可用localhost
·将文件.keystore放到Tomcat服务器的conf目录下
# cp .keystore /usr/local/tomcat/server/conf/
·修改conf/server.xml文件，修改加密连接器，添加keystoreFile与keystorePass
