Product Registration is FREE and includes many benefits:
* Notification of new versions, patches, and updates
* Special offers on Oracle products, services and training
* Access to early releases and documentation
Product and system data will be collected. If your configuration
supports a browser, the JDK Product Registration form will
be presented. If you do not register, none of this information
will be saved. You may also register your JDK later by
opening the register.html file (located in the JDK installation
directory) in a browser.
For more information on what data Registration collects and
how it is managed and used, see:

3.查看文件指向
[root@rrcy java]# ls -l
total 4
lrwxrwxrwx 1 root root 16 Jun 26 14:02 default -> /usr/java/latest
drwxr-xr-x 9 root root 4096 Jun 26 14:02 jdk1.6.0_31
lrwxrwxrwx 1 root root 21 Jun 26 14:02 latest -> /usr/java/jdk1.6.0_31
4.设置java环境:/etc/profile.d/在最后添加如下内容，然后上传
root@rrcy tomcat]# vim /etc/profile.d/java.sh
export JAVA_HOME=/usr/java/jdk1.6.0_31
export PATH=$PATH:$JAVA_HOME/bin
5.执行环境变量：
[root@rrcy java]# . /etc/profile.d/java.sh
6.查看版本：
[root@rrcy java]# java -version
java version "1.5.0"
gij (GNU libgcj) version 4.4.7 20120313 (Red Hat 4.4.7-4)

7.是否成功安装JDK验证：
# java
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]
(to execute a jar file)
where options include:
-d32 use a 32-bit data model if available
-d64 use a 64-bit data model if available
-server to select the "server" VM
二、安装配置tomcat+apache
1.下载安装包
apache-tomcat-7.0.54.tar.gz
2.解压安装包
tar -xf apache-tomcat-7.0.54.tar.gz -C /usr/local
3.创建tomcat连接
cd /usr/local
ln -sv apache-tomcat-7.0.54 tomcat
4.查看连接是否成功
[root@rrcy local]# ll
lrwxrwxrwx 1 root root 20 Jun 26 12:56 tomcat -> apache-tomcat-7.0.54
5.创建tomcat环境变量文件
[root@rrcy ~]# vim /etc/profile.d/tomcat.sh
export CATALINA_HOME=/usr/local/tomcat
export PATH=$PATH:$CATALINA_HOME/bin
6.运行环境变量
[root@rrcy ~]# . /etc/profile.d/tomcat.sh
[root@rrcy tomcat]# catalina.sh version
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Server version: Apache Tomcat/7.0.54

[root@rrcy tomcat]#
7.开起tomcat服务
[root@rrcy tomcat]# catalina.sh start
8.查看8080 8009 端口
[root@rrcy init.d]# netstat -tnlp

9.创建启动服务
[root@rrcy conf]# vim /etc/init.d/tomcat
JAVA_HOME=/usr/java/latest
CATALINA_HOME=/usr/local/tomcat
export JAVA_HOME CATALINA_HOME
exec $CATALINA_HOME/bin/catalina.sh $*
[root@rrcy conf]# chmod +x /etc/init.d/tomcat
[root@rrcy conf]# 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/java/latest
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
