Linux卸载jdk

　　

第一、以root账号登录如下

[whutsun@localhost ~]$ su root

Password: 

第二、查看系统已安装的jdk

[root@localhost whutsun]# rpm -qa|grep jdk

jdk-1.6.0_22-fcs

第三、卸载jdk

[root@localhost whutsun]# rpm -e --nodeps jdk-1.6.0_22-fcs

/var/tmp/rpm-tmp.17570: line 466: /usr/java/jdk1.6.0_22/bin/java: No such file or directory

第四、再次卸载，提示JDK已被删除，系统没有安装jdk

[root@localhost whutsun]# rpm -e --nodeps jdk-1.6.0_22-fcs

error: package jdk-1.6.0_22-fcs is not installed

下面是卸载与JAVA相关的文件，命令用法与上面相同，如果一次要需要卸载多个文件，直接在空格分隔即可，如：rpm -e --nodeps sun-javadb-javadoc-10.5.3-0.2 sun-javadb-common-10.5.3-0.2

 

[root@localhost whutsun]# rpm -qa|grep jdk

[root@localhost whutsun]# rpm -qa|grep java

sun-javadb-core-10.5.3-0.2

sun-javadb-demo-10.5.3-0.2

sun-javadb-javadoc-10.5.3-0.2

sun-javadb-common-10.5.3-0.2

sun-javadb-docs-10.5.3-0.2

[root@localhost whutsun]# rpm -e --nodeps sun-javadb-core-10.5.3-0.2

[root@localhost whutsun]# rpm -qa|grep java

sun-javadb-demo-10.5.3-0.2

sun-javadb-javadoc-10.5.3-0.2

sun-javadb-common-10.5.3-0.2

sun-javadb-docs-10.5.3-0.2

[root@localhost whutsun]# rpm -e --nodeps sun-javadb-demo-10.5.3-0.2

[root@localhost whutsun]# rpm -qa|grep java

sun-javadb-javadoc-10.5.3-0.2

sun-javadb-common-10.5.3-0.2

sun-javadb-docs-10.5.3-0.2

[root@localhost whutsun]# rpm -e --nodeps sun-javadb-javadoc-10.5.3-0.2 sun-javadb-common-10.5.3-0.2

[root@localhost whutsun]# rpm -qa|grep java

sun-javadb-docs-10.5.3-0.2

[root@localhost whutsun]# rpm -e --nodeps sun-javadb-docs-10.5.3-0.2

至此所有与JAVA相关的文件删除完成。
