centOS7系统安装jdk异常报错解决方法

centos安装jdk-7u15-linux-x64.rpm异常解决方法 首先先将jdk-7u15-linux-x64.rpm放到usr/locl/src目录下

[root@localhost ~]# rpm -ivh jdk-7u15-linux-x64.rpm  Preparing...                ########################################### [100%]    1:jdk                    ########################################### [100%] Unpacking JAR files...         rt.jar... Error: Could not open input file: /usr/java/jdk1.7.0_15/jre/lib/rt.pack         jsse.jar... Error: Could not open input file: /usr/java/jdk1.7.0_15/jre/lib/jsse.pack         charsets.jar... Error: Could not open input file: /usr/java/jdk1.7.0_15/jre/lib/charsets.pack         tools.jar... Error: Could not open input file: /usr/java/jdk1.7.0_15/lib/tools.pack         localedata.jar... Error: Could not open input file: /usr/java/jdk1.7.0_15/jre/lib/ext/localedata.pack

  报出这个异常的解决方法是配置java的环境变量  

[root@localhost ~]# vi /etc/profile  末尾加上 set JAVA_HOME=/usr/java/jdk1.7.0_15 export JAVA_HOME set PATH=$PATH:$JAVA_HOME export PATH set CLASSPATH=.:JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export CLASSPATH  保存 [root@localhost ~]# java -version java version "1.7.0_15" Java(TM) SE Runtime Environment (build 1.7.0_15-b03) Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)
