CentOS部署Java开发环境

一、安装jdk 
 
jdk下载地址：http://www.Oracle.com/technetwork/java/javase/downloads/jdk-6u31-download-1501634.html
 
1.jdk上传到linux
 
[[email protected] tools]# ll
 
total 167060
 
-rw-r--r-- 1 root root 85292206 Nov  8  2012 jdk-6u31-linux-i586.bin
 
-rw-r--r-- 1 root root 85581913 Oct 24  2012 jdk-6u31-linux-x64.bin
 
一个是32位的一个是64位的，以32位的为例
 
[[email protected] tools]# mkdir /usr/local/java    ##建立目录
 
[[email protected] tools]# mv jdk-6u31-linux-i586.bin /usr/local/java/
 
移动软件包到/usr/local/java下
 
[[email protected] tools]# cd /usr/local/java/
 
[[email protected] java]# chmod 777 jdk-6u31-linux-i586.bin ##给安装包执行权限  
 
[[email protected] java]# ./jdk-6u31-linux-i586.bin ##安装出现Done 时安装成功
 
设置环境变量
 
[[email protected] java]# vim /etc/profile
 
export JAVA_HOME=/usr/local/java/jdk1.6.0_31
 
export CLASSPATH=.:%JAVA_HOME%/lib/dt.jar:%JAVA_HOME%/lib/tools.jar
 
export PATH=$PATH:$JAVA_HOME/bin
 
[[email protected] java]# source /etc/profile
 
验证java安装是否成功
 
[[email protected] java]# java -version
 
java version "1.6.0_31"
 
Java(TM) SE Runtime Environment (build 1.6.0_31-b04)
 
Java HotSpot(TM) Client VM (build 20.6-b01, mixed mode, sharing)
 
[[email protected] java]# javac -version
 
javac 1.6.0_31
 
写个java程序运行测试下
 

[[email protected] java]# javac HelloWorld.java 
 
HelloWorld.java:2: cannot find symbol
 
symbol  : class string
 
location: class HelloWorld
 
        public static void main(string args[]){
 
                                ^
 
HelloWorld.java:3: package system does not exist
 
                system.out.println("hello world");
 
                      ^
 
2 errors
 
提示有2处错误，很智能的可以看到哪里写错了。
 

在执行
 
[[email protected] java]# javac HelloWorld.java
 
[[email protected] java]# ll
 
total 83412
 
-rw-r--r--  1 root root      425 Oct 11 19:46 HelloWorld.class
 
-rw-r--r--  1 root root      109 Oct 11 19:46 HelloWorld.java
 
drwxr-xr-x 10 root root    4096 Oct 11 19:33 jdk1.6.0_31
 
-rwxrwxrwx  1 root root 85292206 Nov  8  2012 jdk-6u31-linux-i586.bin
 
看生成了.class文件
 
[[email protected] java]# java HelloWorld
 
hello world
 
然后在在屏幕上打印出来 hello world了

二、安装tomcat
 
tomcat下载地址：
 
[[email protected] java]# wget http://archive.apache.org/dist/tomcat/tomcat-7/v7.0.26/bin/apache-tomcat-7.0.26.tar.gz
 
[[email protected] java]# tar zxf apache-tomcat-7.0.26.tar.gz
 
[[email protected] java]# mkdir /usr/local/tomcat
 
[[email protected] java]# cp -ar apache-tomcat-7.0.26/* /usr/local/tomcat/
 
[[email protected] java]# cd /usr/local/tomcat/bin/
 
[[email protected] java]# chmod 777 startup.sh 
 
[[email protected] java]# chmod 777 catalina.sh

[[email protected] 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/java/jdk1.6.0_31
 
Using CLASSPATH:      /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
 
查看本机ip

浏览器中输入http://192.168.1.29:8080/
 
显示tomcat主页面
