一:安装jdk
下载将jdk加压后放到/usr/local目录下：
[[email protected] ~]#chmod 755 jdk-6u5-linux-x64.bin
[[email protected] ~]# ./jdk-6u5-linux-x64.bin
[[email protected] ~]#mv jdk1.6.0_05 /usr/local
建立/usr/local/下的jdk软连接方便以后版本升级 ：
[[email protected] ~]# ln -s /usr/local/jdk1.6.0_05/ /usr/local/jdk
配置环境变量：
在 /etc/profile 中的文件末尾加入以下内容：
JAVA_HOME=/usr/local/jdk1.6.0_05
JAVA_BIN=/usr/local/jdk1.6.0_05/bin
PATH=$PATH:$JAVA_BIN
CLASSPATH=$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME JAVA_BIN PATH CLASSPATH
保存退出
[[email protected] ~]source /etc/profile
查看java环境变量是否生效
[[email protected] ~]# java -version
java version "1.6.0_05"
Java(TM) SE Runtime Environment (build 1.6.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 10.0-b19, mixed mode)
测试成功
二：安装tomcat
二．下载安装tomcat（http://tomcat.apache.org/）
[[email protected] ~]# unzip apache-tomcat-6.0.30.zip
[[email protected] ~]# mv apache-tomcat-6.0.30/ /usr/local/
[[email protected] ~]cd /usr/local/
[[email protected] local]# ln -s /usr/local/apache-tomcat-6.0.30/ /usr/local/tomcat
[[email protected] local]# cd tomcat/bin/
[[email protected] bin]#ls
[[email protected] bin]#vim catalina.sh
文件末尾添加以下内容：
CATALINA_HOME=/usr/local/apache-tomcat-6.0.41/
[[email protected] local]#chmod +x *.sh
三．启动tomcat服务器
[[email protected] tomcat]# /usr/local/tomcat /bin/catalina.sh start
Using CATALINA_BASE: /usr/local/apache-tomcat-6.0.30/
Using CATALINA_HOME: /usr/local/apache-tomcat-6.0.30/
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-6.0.30//temp
Using JRE_HOME: /usr/local/jdk1.6.0_05
Using CLASSPATH: /usr/local/apache-tomcat-6.0.30//bin/bootstrap.jar
[[email protected] logs]# cd /usr/local/tomcat/logs/
[[email protected] logs]# tail -f catalina.out
Aug 25, 2014 10:50:16 AM org.apache.catalina.startup.HostConfig deployDirectory
INFO: Deploying web application directory host-manager
Aug 25, 2014 10:50:16 AM org.apache.coyote.http11.Http11Protocol start

Aug 25, 2014 10:50:16 AM org.apache.catalina.startup.Catalina start
INFO: Server startup in 836 ms
四．在浏览器中输入
http://localhost:8080/（如果不是本机，则输入对应的ip地址）
测试出现tomcat页面则测试成功

【附加：
四. 测试jdk
1. 用文本编辑器新建一个Test.java文件，在其中输入以下代码并保存：
public class test {
public static void main(String args[]) {
System.out.println("A new jdk test !");
}
}
2. 编译：在shell终端执行命令 javac Test.java
3. 运行：在shell终端执行命令 java Test
当shell下出现“A new jdk test !”字样则jdk运行正常。
五. 卸载jdk
·找到jdk安装目录的_uninst子目录
·在shell终端执行命令./uninstall.sh即可卸载jdk。】
