jdk1.7 tomcat-7安装由于软件下载地址经常有变动，所以不能直接wget，还是直接到网上点击下载
下载jdk
http://www.Oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
选中Accept License Agreement，选择64位的jdk-7u65-linux-x64.tar.gz，如下图
下载tomcat,tomcat版本会更新，以下载版本号为准
http://tomcat.apache.org/download-70.cgi
把软件上传到/tmp中
安装jdk
cd /tmptar -zxvf jdk-7u60-linux-x64.gzmv jdk1.7.0_60 /usrvi /etc/PRofile
在prifile文件结尾插入下一段
export JAVA_HOME=/usr/jdk1.7.0_60export JAVA_BIN=/usr/jdk1.7.0_60/binexport PATH=$PATH:$JAVA_HOME/binexport CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jarexport PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH保存文档，然后让配置生效
source /etc/profile
安装tomcat
tar -zxvf apache-tomcat-7.0.54.tar.gzcp -r /tmp/apache-tomcat-7.0.54 /datacd /datamv apache-tomcat-7.0.54/ tomcatcd /data/tomcat/bin./startup.sh
用浏览器打开如下的网页http://localhost:8080/;如果你见到Tomcat的网页（index.jsp），证明Tomcat安装成功，并已经启动．jdk环境错误，$JAVA_HOME这个变量没有定义时，解决情况如下cd /data/tomcat/binvi setclasspath.sh
在setclasspath.sh中插入红色部分
