怎么卸载jdk(java官方api中文文档)

一、查看Jdk的安装路径：

whereis java

which java （java执行路径）

echo $JAVA_HOME

echo $PATH

三、删除

[root@localhost ~]# whereis java

java: /usr/bin/java /usr/lib/java /etc/java /usr/share/java /usr/share/man/man1/java.1.gz

[root@localhost ~]# rm -rf /usr/bin/java /usr/lib/java /etc/java /usr/share/java /usr/share/man/man1/java.1.gz

四、删除

[root@localhost ~]# which java

[root@localhost ~]# rm -rf /usr/bin/java

五、删除

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

copy-jdk-configs-3.3-10.el7_5.noarch

java-1.7.0-openjdk-headless-1.7.0.191-2.6.15.5.el7.x86_64

java-1.8.0-openjdk-headless-1.8.0.181-7.b13.el7.x86_64

java-1.8.0-openjdk-1.8.0.181-7.b13.el7.x86_64

java-1.7.0-openjdk-1.7.0.191-2.6.15.5.el7.x86_64

[root@localhost ~]# rpm -e --nodeps copy-jdk-configs-3.3-10.el7_5.noarch java-1.7.0-openjdk-headless-1.7.0.191-2.6.15.5.el7.x86_64

[root@localhost ~]# rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.181-7.b13.el7.x86_64 java-1.8.0-openjdk-1.8.0.181-7.b13.el7.x86_64

[root@localhost ~]# rpm -e --nodeps java-1.7.0-openjdk-1.7.0.191-2.6.15.5.el7.x86_64

六、检查
