  (2)命令    vim /etc/profile
               export JAVA_HOME=/usr/local/lnmp/jdk(zuihou)
               export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
               export PATH=$PATH:$JAVA_HOME/bin
             source /etc/profile
  (3)检测     echo $JAVA_HOME
               /usr/local/lnmp/jdk
             echo $PATH
               /usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/lnmp/mysql/bin:
        /root/bin:/usr/local/lnmp/mysql/bin:/usr/local/lnmp/php/bin/:/usr/local/lnmp/jdk/bin
             echo $CLASSPATH
               .:/usr/local/lnmp/jdk/lib:/usr/local/lnmp/jdk/jre/lib
             which java
              /usr/local/lnmp/jdk/bin/java
             which javac
              /usr/local/lnmp/jdk/bin/javac
  (4)java测试 vim /root/test.java
                public class test {
                      public static void main(String[] args)
